A conversation is not a business meeting at work or with your family. It is a personal or informal talk that takes place in the restaurant, in a car or walking on the street on your way to work.
It can make or break a relationship. It can make a career successful. It can make new friends. It can just brighten up another person’s life. It can change the world!
Here are some ways to make a conversation bring meaning to you and others.
Before starting a conversation, be clear about what you want to achieve. Knowing your purpose beforehand allows you to keep your conversation to the point and never get lost out of the way.
Start a topic that is very timely and appropriate. The starting point has to be depending on your relationship with the person you are talking to and the situation the person or both of you are going through. Starting the conversation with the right topic sets the tone that brings both sides at ease.
Come up with something that will make both of you interested. This allows the other person to be drawn more to speak up. Discovering common likes and dislikes opens up a bond (纽带) between two people.
Put yourself in the shoes of the other person. Think how the other person feels at that moment. Feeling how the other person feels helps you to be in his position.
One of the most difficult tasks to do in a conversation is really listening. Do not prepare for what to say while the other person is talking. Do not just keep quiet because you want to give the other person a time to talk. The proof that you really listen is to repeat your understanding of what was said in your own words.
After you have spoken, give the other person a time to talk. There are some people who like to talk about themselves. If you are one of them, try to be less selfish. A conversation is not a monologue (独角戏) or an interview.
Managing a conversation shows the kind of person you are. You do not have to wait for the other person to lead the discussion. You can do this. No matter who you are, if you lead a talk, you make a difference.

Scientists, doctors and mental health professionals have been studying the connection between colors and mood for years. Many now believe that colors can not only bring about emotional reactions, but can also correct mood. Colors behave in three basic ways: active, passive and neutral (中和的).
Active colors are warm colors, including yellow, orange and red. These colors bring confidence. Warm colors can also bring cheerful attitudes. Yellows and golden colors work well in offices, kitchens and study areas. Reds heat up a room. Passive colors or cool colors make people calm, quiet and satisfied. Bedrooms, private areas and bathrooms are great places for blues and greens. Beige, gray and white are thought of as neutral colors. They help to put the focus on other colors or serve to tone down colors that might otherwise be overpowering on their own.
You can easily change the look or feel of a room by making good use of different colors. Mixing and matching colors is an excellent way to balance color and emotion, and provide a welcoming feel for guests.
To create a feeling of warmth and comfort in a room, use bright, warm colors like yellow, orange and red. These colors are good choices for rooms that appear cool due to limited sunlight. Yellow adds cheerfulness to dull rooms. You can add yellows to rooms which are not closely related to happy thoughts, such as kitchens and laundry room. In rooms where there's plenty of sunshine, cool colors can provide a calming environment. Sage greens and sky blues are perfect for bedrooms, playrooms and activity areas. Neutral colors, such as pale gray, white and beige, send a peaceful message to your brain. It's not a coincidence that most doctor's offices, coffee shops and mental health centers are decorated in neutrals.
To make your wall color choices better, pick out furniture that will provide a visual contrast. Cool colors make a room seem larger than it is and warm colors make rooms feel smaller.

I used to be the messiest person alive. Over the years, through watching others and by trial and error, I have finally found ways to come up with plans, organize them and follow through with them.
Make an outline of everything you need to have and do to make your plan happen. Make a list of all of the steps that need to be accomplished and think about what needs to be done.
Detail everything thoroughly and read over it so you can start coming up with some mental solutions of how to carry out your plans.
You should ensure that if for some reason way one doesn’t work, you have way two and way three to lean back on. Therefore, different ways are needed at hand. It’s just a matter of being organized. Chances are that there is always more than one way of doing things, and chances are that if one of those ways doesn’t work, one of the other ones will.
Committing yourself to finishing at least part if not all of your plan at once is also necessary. It will show that you not only have initiative to get things rolling, but that you are interested in the results obtained with making the move to get everything done.
If you make a commitment to finish before a specific time, make sure that you carry that out, and be sure to do everything in the way you said you would, within the time-frame you set for yourself.
Don’t try to tackle more things all at a time. All that does is delay your progress, distract you and make you lose your interest, motivation and energy.
Carrying out an effective plan requires being as organized as possible. You will only achieve this by sticking to the order of the plan and not deviating or trying to do more at a time.
Last but not the least, you should never abandon things mid-project. It will only annoy everyone around you including yourself. Unfinished plans are a waste of time, energy and, in some cases, even money.
So, don’t be afraid of organization. The older we get, the more necessary it becomes to have the skills necessary to follow through with confidence and to be able to carry through plans in an organized and manageable way. It pays to be organized, after all.

The 2014 Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights. A big change in lighting efficiency is under way around the world.
Save and green
LEDs use less energy than other forms of lighting. A typical LED bulb(灯泡) can produce around 83 lumens per watt — a measure of how much brightness you can get from a unit of electrical power — much more efficient than other lighting facilities.
LEDs produce light by passing electric current through a semiconductor, while traditional bulbs pass current through a wire. The wasted heat energy is chiefly why traditional bulbs are so much less efficient.
LEDs also last about 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years if you used one for about four hours a day.
Lighting the world
The lighting application is not only in homes. LEDs are also being used for street lights, public holiday and decorative displays, commercial buildings, and other large energy users.
Car lighting is another application where LEDs are making progress. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for night-time use.
LEDs also hold promise for bringing light to the more than 1.5 billion people around the world without access to electricity, the Royal Swedish Academy of Sciences noted. Indeed, several proposed solutions to energy poverty include the distribution of LED lights, particularly solar-powered ones.
Digital displays
Without blue LEDs, the world wouldn’t have back-lit smart phones, TV and computer LCD screens, blu-ray(蓝光) players, many forms of lighting, and countless other products.
In the electronics industry, LEDs provide back lighting for the liquid crystal displays (LCDs) in many smart phones, laptops, and televisions. The LEDs are more energy efficient and allow for very thin displays.
Blu-ray players use blue LED lasers(激光) to read data off a digital optical disc. When these systems switched from using an infrared(红外线) laser to a blue LED laser, it became possible to store five to 10 times as much data.
LEDs are now being explored for their potential to transmit(传送) data from the Internet across open space, similar to WiFi. Such a system could transmit a lot more data than WiFi alone. This high bandwidth is possible because LEDs can turn on and off millions of times per second.
The rise of LED lighting came at a time when people were just starting to be concerned about global warming. Because of LEDs’ energy efficiency, using them for the world’s lighting would have “an extreme impact” on society.

Chinese parents are very generous when it comes to educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the US or Australia. They also want their children to take extra-course activities where they will either learn a musical instrument or ballet, or other classes that will give them a head start in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend unreasonable amount of money on education. Even poor couples will buy computers for their sons or daughters.
However, what most parents fail to see is that the best education they can give to their children is usually very cheap.
Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize though, is that today’s children lack self-respect and self-confidence.
The reasons are that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills: they need to be confident, happy and clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of confidence. These activities are not only teaching a child to work, but rather to think, and to use his mind. And that is more important.

A scientist once said that studying the stars from the earth is something like looking up at the sky from the bottom of a swimming pool. Even on the clearest night the earth’s dense atmosphere will dim stars in the sky as it screens out (遮挡) 30 percent of their light. Air turbulence (湍流) causes stars to winkle. Through a telescope, the stars seem to jump around dizzily.
Because the moon has no atmosphere, astronomers are looking forward to setting up an observatory there. On the moon, there will be no clouds to obscure the view. The sky will appear dark at all times, so astronomers can work twenty-four hours a day. Because there is not air turbulence, the stars will steady through a telescope.
Because the moon is relatively near the earth, moon-based astronomers will see the stars in familiar patterns known on earth. They will not need new star maps of the sky. Stars seen from the moon will appear to move very slowly. Because the earth rotates (自转) on its axis once every twenty-four hours, earth-based astronomers see the stars hurry across the sky each night. The moon rotates on its axis only once a month. To astronomers on the moon, the stars will appear to stand almost still. Moon-based astronomers will have much more time to focus their telescopes and take time ---exposure photographs.
On the earth, man-made radio noises jam the airwaves and interfere with the reception of radio signals from certain stars. A radio telescope located on the far side of the moon will be permanently protected from such interference.
It won’t be easy to put telescopes on the moon. However, astronomers are certain the job can be done. They are convinced that the moon is an ideal place to set up an observatory.

Some people believe that greed and selfishness has become the basis of modern society. We should return to the old traditions of family and community, and then we will have a better life. To what extent do you agree or disagree with the above opinion?
In this fast-paced world, many values are undergoing major changes. While people traditionally prioritize(区分优先次序) caring, sharing and generosity in life and work, modern people seem to be more self-absorbed and self-concerned.
Modern people act selfishly to survive the harsh competition of life. They say that it is a jungle out there. To survive, you have to fight with whatever means that come handy. Obviously greedy and selfishness go perfectly well with such ideas. In a company, employees do everything they can to get better pay and higher position, even at the cost of colleagues. We are in any way advocating any selfish conduct. It is just that people are pressured to act in a certain way due to outside influences.
In spite of common practice, it is hard to conclude that modern society is built on greed and selfishness, both of which are not newly invented vocabulary. In ancient times people also did greedy and selfish things though such behaviors were more condemned(谴责) then. But we cannot ignore the fact that people in the past lived a relatively more isolated life and faced less pressure compared with their modern twins.
Are we happier to share with others and be generous to them? There is no fixed answer either. Some people take great pleasure helping and giving to others while others feel happy doing the opposite. But I personally think that people should not be too selfish. Caring for others can actually encourage the development of a mutually beneficial relationship.
In conclusion, modern people appear to be more self-centered than those in the past due to strong outside pressure. However, we should encourage people to know the importance of being caring and generous and to build a mutually beneficial relationship with others.

Things You Should Insist on No Matter What People Say
Life can get pretty crazy at times． Happiness is dependent upon ourselves，and there are some things in life you should always insist on doing，no matter what others have to say about it．Here is a list of some things you should always do．
1．Learn from your mistakes
No matter what people say，you will make mistakes in your life．Life is a learning process in itself．Some people will make you feel bad about your mistakes，or insult you for making them． Accept your mistakes fully and really figure out what went wrong．
2．Embrace change and creativity
A popular proverb is，“You cannot solve a problem in the same state of consciences that created it．” Change and creativity are vital in today’s world．Things are always changing，so why should we be any different?
3．Appreciate what you have This can take away from our happiness．Sometimes you just need to sit back and be happy about where your life is right now，and what you have to show for it. Sure people might tell you it’s not good enough，but don’t listen to them．It is good enough，and it gives you a sense of pride when you can enjoy the things you already have in life．
4．Listen to your heart
Sometimes you just need to follow your instincts and do what your heart tells you. There are some situations，like relationships，that rely more on your heart than on your head．People will surely tell you differently，but you should always insist on listening to what you want and feel. Again，you are the one who lives with your choices，and you are the one that has to live with the“what ifs．”
More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons．Exercise strengthens the heart muscle，reduces blood pressure and help to prevent muscles from changing into fat．Physical exercise is just as important for children．
Exercise and food affect growing speed in young lab animals．Baby mice start running as soon as they are big enough to use an exercise wheel in their cage．If they get extra food and run a lot，they will grow as much as 1.5 times bigger than normal．
The same differences in growing speed might be found between active and inactive children．Physical exercise helps active children grow faster than inactive children．One experiment shows that the brains of the mice that had enough exercise weighed about 3％more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise．
The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected．
The good effects of physical exercise are not limited to children and middle-aged people．Exercise continues to be an important part of our lives after we grow old．For example，people over 50 years old begin to lose calcium(钙) from their bones，which get weaker and can break easily．Physical exercise，however，helps to strengthen the bones and to prevent them from losing calcium．Of course，old people can take medicines to prevent themselves from suffering from losing calcium．But the medicines they take increase the chance of developing some kind of cancer(癌)．So physical exercise is a much safer treatment(治疗)．

Cheating is common in various kinds of exams in college. Students don’t feel shame to cheat in exams. They know that if caught cheating in an exam, the punishment will not be serious. This leads to frequent cheating in exams.
At the University of Nevada, after students photographed test questions with their cellphone cameras, transmitted them to classmates outside the exam room and got the answers back in text messages, the university put in place a new monitoring system.
With their electronic tools, students these days find it easier to cheat. So college officials find themselves in a new game of cat and mouse, trying to gain an advantage over would-be cheats this exam season with a range of strategies—cutting off Internet access from laptops, or demanding the surrender of cellphones before tests.
Mr. Dapremont said technology had made cheating easier, but added that plagiarism（剽窃）in writing papers was probably a bigger problem because students can easily lift other people’s writings off the Internet.
Still, some students said they thought cheating these days was more a product of an attitude, not the tool at hand. Pressure to succeed sometimes clouds everything and makes people do things that they shouldn’t do. Students today feel more pressure to do well in order to graduate from school and secure a job.
Whatever the reasons for cheating, college officials say the battle against it is wearing them out. First, people who cheat in exams will lose interest in studying. Second, they believe studying isn’t meaningful. Even though they don’t do anything, they can still pass. Third, people who cheat in exams will influence others. Plenty of hardworking people will see that their results are lower than people who cheat in exams. Thus, we must prevent cheating in exams. We reduce the opportunities for cheating in exams.
The vast majority of Americans still believe that honesty is an important part of the American character. For that reason, there are numerous watchdog committees at all level of society. Although signs of dishonesty in school, business, and government seem much more numerous in recent years than in the past, could that because we are getting better at revealing such dishonesty?
Many educators feel that as students gain confidence in themselves and their abilities, they are less likely to cheat. Surprisingly, some efforts to prevent cheating may actually encourage cheating—a person may feel “ they don’t trust me anyway”, and be tempted to “ beat the system”. Distrust can be contagious（可传染的）. But, so can trust.

If you are worried about things and are under a lot of stress at work or school, then you are probably not sleeping well. Worry can keep you awake, tossing(翻来覆去) and turning in bed until the early hours of the morning when you eventually fall asleep. When you wake up, you don’t feel refreshed, but tired and worn out and unable to face a new day.
Dr. Henry Winkle, in a recent newspaper article entitled Stress and Sleep, indicates that . Dr. Winkle says, “The more we worry, the less we sleep, the more we are unable to deal with stress. If we can find a way to get a good night’s sleep,” he adds, “we can often find the energy to deal with what’s worrying us.”
So, what is a good night’s sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours is about average amount, though strangely enough, sleeping longer often gives you a headache instead of making you feel more refreshed.
Dr. Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help, but coffee or tea should be avoided as they contain caffeine and will keep you awake. “When you put the light out,” Dr. Winkle says, “concentrate on relaxing your muscles, working slowly up from your feet, and you’ll be asleep before you know it.”What is the best title of the passage? (Please answer within 5 words)
Which sentence in the passage can be replaced by the following one?
People shouldn’t go to sleep immediately but should take a break after working late in the night.
Please fill in the blank in the second paragraph with proper words or phrases to complete the sentence. (Please answer within 10 words)
Someone says that the longer you sleep, the better you feel. Try to find an argument from the passage against the idea. (Please answer within 15 words)

We all have goals that we are moving towards and making a great effort to achieve. This is a good thing. Or can it be bad? How many of us never reach our goals and yet we have tried so hard and really thought about nothing else? I believe the mistake most of us make is that we do not focus on our present situation.
Let me explain. Most of us see our present situation as a stepping stone that we use simply as a means of reaching our final destination. We don’t take time to truly appreciate where we are today and all the great things we already have in our lives. We should focus our attention on the journey and not on the destination, or we will miss the beautiful scenery along the way.
Let’s use our job as an example. Now most of us want a promotion. We have plans to become the manager or general manager in our companies. Unfortunately, most of us will never reach the goal, but will watch others achieve our goal instead.
What we should be doing is focusing on the job we are currently in now. Forget where we want to get to and just focus on the present. You see, what we can control is our performance in our current job. We can decide to be the best we possibly can in our current job. Now this may mean furthe
r education to have the skills we currently do not have. It may mean working harder to produce better results than our colleagues. It could simply be a change of attitude, such as stopping complaining and becoming a more devoted and supportive employee. By doing our current job to the best of our abilities, we in fact give ourselves the best chance of promotion.
So the best thing for all of us to do to achieve our go
als is to just focus on what we have and where we are now. Do the best and be the best we possibly can in our current situations
, and we will give ourselves the very best chance of reaching our goals in the future. We have heard the old sayings and they are true: “Rome wasn’t built in a day.”, “Patience is a virtue”, and so on.
Have patience, have appreciation of what we already have, and take time to help ourselves be the very best we can. Do these things and we will all reach our goals, but more importantly, we will enjoy our life every day.

Color use in nature
Nature is very colorful, full of different hues（色调）that delight the eye. What makes these colors and why do they exist?
Causes of Colors in Nature
Colors in nature are formed in two ways. Pigments, like the melanin in skin and many animal furs, produce most blacks, browns, reds and yellows. Most plants are green due to chlorophyll（叶绿素）. Other colors are caused by structure, like many greens, blues, and whites. Blue bird’s feathers actually contain black pigment, but their structure causes them to appear blue. The scattering of light by tiny dust particles in the air, viewed against the black background of space, makes the sky look blue too.
Color Use in Plants
Color has a great effect on the survival of plants and animals. Flowers have bright hues and patterns to attract insects. These insects move from one flower to another, making sure seeds are produced. Bees can see colors we cannot, i.e. ultraviolet, and follow these patterns of stripes or dots to the inside of the flower.
Not only flowers but also fruits use color for the good of the plant. An unripe fruit mixes in with the leaves, but ripe berries contrast, becoming more appealing to the creatures who eat them. Birds are especially drawn to red fruit, and in turn help the plant by broadcasting its seeds.
Camouflage（伪装）in Nature
Many colors and patterns camouflage animals who want to avoid enemies. Some animals have damaging shapes to break up their outline, so an enemy will not recognize them. The eye, a very recognizable animal characteristic, is often disguised by a black stripe or patch. Light color below makes up for the shadow on the underside of many fish, amphibians and mammals.
Some animals even change colors to better camouflage themselves, seasonally like the snowshoe hare.
Warning Coloration and Mimicry（动态伪装）
Warning colors make an animal more visible rather than hidden. These usually indicate a negative aspect of the animal, like the bad taste of a monarch butterfly, smelly smell or painful bite of a bee. Usually black and a contrasting color (white, yellow, orange or red) form a striking pattern in these creatures, and frighten their enemies away. Nature is tricky, though, and sometimes harmless creatures pretend the patterns of harmful ones to scare off animals living on meat too.
Social Coloration in Nature
Sometimes coloration is important socially. Male birds, typically more colorful, defend their territories and attract females. Eggs may use color and pattern to remain hidden. When they hatch, parents feed the nestlings when they see the bright pattern in their gaping mouths.
