The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colors in meats and other food additives (添加剂) caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin (青霉素) to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.According to this passage, we can know _____.
| A．perhaps most kinds of cancer are related to what people eat |
| B．perhaps most of human illness is caused by what we eat |
| C．cancer was discovered in 1945 |
| D．science has made food unfit to eat |

Why are so many people afraid to fail? Quite simply because we forget that failure is part of the human life and that every person has the right to fail. Every person is able to fight failure and finally succeed.
Most parents work hard at preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards(标准). When a child finishes making a table, the mother describes it as “perfect” even though it doesn’t stand still. Another way is to blame others. If John fails in science, his teacher is unfair or stupid.
There’s a problem with the two ways. It makes a child unprepared for life in the real world. Young children need to learn that no one can be best at everything, no one can win all the time, and that it’s possible to enjoy a game even when you don’t win. A child often feels terrible, of course, when he is not invited to a birthday party, or is not chosen into a football team. But parents should not say “It doesn’t matter.” quickly. The young should be allowed to experience failure and be helped to come out of it.
Failure never gives people pleasure. It hurts both adults and children. But it can be really good to your life when you learn to use it. You must learn to ask “Why did I fail?” Don’t blame anyone else. Ask yourself what you did wrong and how you can improve. If someone else can help, don’t be shy about asking them. Success just repeats what has been done. It is not as good a teacher as failure. You can learn how to give a good party from an unsuccessful one.How do most parents prevent their children from failure?
| A． They give them some presents. |
| B． They don’t tell them that they have failed. |
| C． They don’t blame others. |
| D． They help them to come out of failure. |
Which of the following does a person need to learn when he fails?
| A． It’s impossible to enjoy a game if he misses it. |
| B． He is the worst of all. |
| C． It’s natural not to win a game and no one can win all the time. |
| D． His teammates are not good enough. |
Which would be the best title for the passage?
| A． Learning from Failure |
| B． Ways of Preventing Failure |
| C． Reasons of Failure |
| D． Getting Pleasure from Failure |

Dolphins(海豚) live in a dark underwater world. It’s often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.
Only other dolphins understand what the sounds mean. Scientists haven’t uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins - and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.
Dolphins often hunt by themselves but still need to stay connected to the group. Since they can’t always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they’re a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.
What’s amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It’s creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother’s or group members’ whistles.
When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it.
Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins’ communication.Sound is important for dolphins because of ______.
| A．their poor sense of direction |
| B．their living environment |
| C．their strong enemies |
| D．their big groups |
The dolphin’s signature whistle ______.
| A．lasts along time |
| B．can travel long distances |
| C．is especially helpful in hunting |
| D．can be recognized by other animals |
The author writes the text mainly to _____.
| A．encourage readers to study dolphins |
| B．tell readers how dolphins communicate |
| C．show how lovely and clever dolphins are |
| D．introduce a special sound made by dolphins |
A baby dolphin gets its name ______.
| A．soon after it was born | B．according to its size |

Life is filled with challenges. As we get older, we come to realize that those challenges are the very things that shape us and make us who we are. It is the same with the challenges that come with friendship. When we are faced with a challenge, we usually have two choices. We can try to beat it off, or we can decide that the thing presenting the challenge isn't worth the trouble and call it quits. Although there are certainly times when calling it quits is the right thing to do, in most cases all that is needed is commitment and communication.
When we are committed to something, it means that no matter how painful or how uncomfortable something is, we will always choose to face it through instead of running away from it. Communication is making a space for discussion and talking about how you feel as opposed to just saying what the other person did wrong. If you can say to a friend, "I got my feelings hurt", rather than "You hurt my feelings", you are going to be able to solve the problem much faster.
In dealing with many challenges that friendship will bring to you, try to see them for what they are: small hurdles you need to jump or get through on your way through life. Nothing is so big that it is impossible to get over, and hurt only serves to make us stronger. It is all part of growing up, it happens to everyone, and some day you will look back on all of this and say, "Hard as it was, it made me who I am today. And that is a good thing."The writer believes that challenges ________.
| A．are always born with friendship |
| B．help build friendship |
| C．are never worth attention |
| D．help us grow |
If your friend hurts your feelings, you are advised to ____.
| A．point out your friend's mistake |
| B．calm yourself down |
| C．start a proper conversation |
| D．run away from it |
The whole passage is centered on the relationship（关系）between ___.
| A．friendship and challenges |
| B．commitment and friendship |
| C．friendship and growth |
| D．challenges and chances |
Many gardeners believe that “talking” to their plants helps them grow---it turns out that they may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language.
For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase(虫荧光素酶), which is what makes fireflies(萤火虫) glow in the dark.
When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”.
While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators(捕食者) like caterpillars(毛虫) away.
What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other.
However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!What’s the best title of the passage?
| A． Plants Can Send Some Gas |
| B． Plants Can Communicate with Each Other |
| C． The “Unseen” Language of Plants |
| D． Plants Can’t Feel Pain |
What does the underlined word “they” in Paragraph 1 mean?
| A． Gardeners | B． Plants |
| C． Scientists | D． Fireflies |
When the plant sent out methyl jasmonate, which of the following statements is NOT TRUE?

Every New Year brings renewed(更新的) expectation for a change, for a better life and for a better you. That’s a wonderful thing, because this fresh start gives us a chance to reinvent our lives and ourselves. Here’s how.
Let go
Many times we are held back by our previous failures,emotions and barriers(障碍). This is all old baggage. Let everything unhappy from the past go. Let go of failures. Let go of fears you’ve built up. Let go of your ideas about what your life has to be like. Let go of long-held beliefs and habits which seem to be burdens(负担) to you.
Clear away distractions(分心)
Clear away email, your favourite blogs and news websites. Clearaway the iPhone or Blackberry, and clear away all the chores that pull at your attention. In fact, if you can, shut off the Internet for a while. You can come back to it after you take a break.
Decide what matters most today
Forget about your goals for all of this year. Instead, decide what you want to do today. What matters most to you and your life? What are you most passionate(热情的) about right now? What excites you? What gives you the most fulfillment(满足感)? Often the answer would be in creating something, making something new, helping others, becoming a better person, and working on a project that you will be proud of. But whatever your answer, have it clear in your mind at the beginning of the day.
Reinvent yourself every day
Every day, you are reborn.Reinvent yourself and your life. Do what matters most to you. It might be the same thing that mattered most yesterday, or it might not be. That isn’t important. What’s important is today---right now! Be passionate, and be happy!
You’ll have a fresh start every single day---not just on January 1 of a new year.Writing this passage, the author seems to be ________.

| C．has been approved | D．is to approve |
Researchers Jose Cordova and Erich Astudillo have discovered a new molecule(分子) that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay(腐烂). The new molecule they call “Keep 32” has been found to kill the bacteria.
The two have applied for a patent(专利) on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep them at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year.
The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they’ve discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey’s. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved.
Over the years many products have come on the scene with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride(氟化物) into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks.The underlined word “them” in Para. 2 refers to _________.
| A．oral care products | B．food products |
| C．new molecules | D．the harmful bacteria |
The phrase “come on the scene” in Para. 4 is closest in meaning to __________.
| A．performed | B．occurred |
| C．existed | D．arrived |
What has been a way to reduce tooth decay and even the loss of teeth over the years?
| A．Using the molecule “Keep 32”. |
| B．Killing the bacteria Mutans. |
| C．Introducing fluoride into drinking water. |
| D．Cooperating with some big companies. |
This passage mainly tells us that ___________.
| A．many health problems are closely connected to tooth decay |
| B．the discovery of a new molecule will greatly benefit health care |
| C．two researchers are discussing their patent with companies |
| D．researchers discover a molecule that can kill tooth decay-causing bacteria |
______ is the ability to do the job______ matters, not where you come from or what you are.

My mother got divorced when I was 5 and was left to raise me and my two younger brothers. She didn’t have a formal education, so she had to work two full-time jobs to make ends meet.
One day several years later, I was determined to help. I told the manager of the Don Carlos Motel in Nana Point that I was 15, so I could get a work permit to work as a maid.
Since then, I’ve started to work alongside some of America’s top leaders, written books, and achieved financial independence. It took a lot of hard work and sacrifices.
But what if I was 15 years old today? Would I be able to accomplish the same things in this new, highly competitive world with so many global challenges? It seems hard work and sacrifices aren’t enough anymore.
Today, you need to be extremely adaptable. To progress in your career, it’s not enough to know one thing well. As my friend Sean Harvey, product manager at Google put it when we were speaking to students, “Today, companies aren’t hiring people for a specific position but rather people who are smart and flexible. The way you prove that is by showing you can do multiple things well.”
People need to take more risks to succeed now than ever. The combination of unemployment and slow wage growth means that we are not only at greater financial risk, but we have to take more risks to succeed.
Luckily, the new Internet world of all-the-time connectedness means that anyone with a hot idea, product or service can create a business out of almost nothing. And success can be quick and big. But that success demands more “out of the box” thinking.
And what about our kids? It makes me think a lot about the future that my 3-years-old daughter faces. But no matter what the future brings, I think the best message I’ll give her is to believe in herself. Life won’t get any easier, but the opportunities will come — as they always have — to those who work hard, adapt as they need to, and trust their abilities.We can infer that the author had _________.
| A．a difficult childhood | B．a lonely childhood |
| C．a normal childhood | D．a happy childhood |
The author achieved financial independence when she was 15 largely due to ______.
| A．her strong leadership |
| B．her boss’s help |
| C．her hard work |
| D．her competitive spirit |
Compared to the past, people who want to succeed now need __________.
| A．more time | B．more money |
| C．to work harder | D．to be more creative |
The author writes the text mainly to __________.
| A．describe her childhood |
| B．give some suggestions about success |
| C．tell a story about her mother |
| D．share some useful parenting skills |
Most nights I lie in bed, ready for an escape from myself, yet a streaming video of everything I ate, how I exercised, the activities of the day won’t stop playing in my mind.
I pause. I breathe. I try to relax once again, but it doesn’t work.
When I’m not exercising — even if I’ve already exercised that day — I’m consumed with anxiety about my next workout. Will something come up and make me miss the gym? What about holidays when the gym is closed?
Exercise has become a disease; it even disguises (伪装，假装) itself as the cure. If I don’t have it as an escape, then what’s left to hold me together? Working out feels like the only way to calm myself, but as soon as I leave the gym or finish a walk, the whole cycle starts over again.
As you might have guessed by now, I suffer from depression and OCD (强迫症). I’m a highly-educated adult woman who knows the risks of this behavior, and yet I can’t stop.
As a society, we’re told over and over that it’s important to exercise. That’s what makes it so easy to keep this addiction a secret; it’s not as obvious as lighting up a cigarette. You can continue to feed your addiction under the guise that you’re just being “healthy”. I not only have to fight the nonstop thoughts in my head but also the “more exercise is better” messages I receive from the media every day.
For me, exercise has become a drug, which is a way to numb the pain I might feel. I wonder what it would be like to “have the problem” of not wanting to go to the gym. It still feels very far away.
Yet I know I can be stronger than this. I can break the cycle I’m in. I can tell my story so as to give up a piece of the secrecy that keeps me sick.
Because no, you don’t want my problem. And finally, neither do I.When the author goes to bed, she___________.
| A．can’t breathe normally | B．can’t fall asleep |
| C．always feels hungry | D．always feels tired |
