Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的) circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
It can be inferred from Para. 2 that __________.
A.foods with natural enzymes help people keep fit |

Researchers at the University of Bedforshire have developed a new technique for powering electronic device(装置). The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio(无线电) waves as power.
Believed to be a world first, the team claims it could eventually eliminate (or get rid of )the need for conventional batteries. The university has now filed a patent application to secure the only rights to the technique.
Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.
The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy―like light waves, sound waves or wind waves―then, in theory, these waves could be used to create power.
“The emerging(新兴的)area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”
The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working prototype(模型)and maybe partner up with the right people and take this to a full product in due course,” he said.
“Power harvesting has a really important part in our future, because, just in this country, we dispose of somewhere between 20,000 and 30,000 tonnes of batteries in landfill(垃圾填理)sites every single year-that is toxic chemicals going into the ground.”
He added that development of the product could also be “commercially beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.
Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple, said, “This type of work is a reflection of the university’s growing reputation and experience in conducting innovative(创新的)research.”

The teacher was handing out test papers when I walk into
the classroom. I was feeling nervously because I had not
prepared well for the exam. I went through the test several time,
but I still could answer the questions. Being afraid of failing the
exam, I put my book under the desk, opened it and started
looking for the answers. The teacher wasn’t looking at for me,
so I copied nothing. Suddenly I felt a hand on my shoulder!
The teacher caught me cheat. I felt too ashamed of myself
to say anything. Unfortunately, the teacher didn’t punish
me for cheating. Instead, he gave me the second chance.
To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't.
“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council.“The benefit was also seen regardless of whether or not people were fat and what social class they came from.”
Study participants(参与者)scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake.
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years.
“We can't say that any person could gain 14 years by doing these things, ”said Dr.Tim Armstrong, a physical activity expert at the World Health Organization.“The 14 years is an average across the population of what's theoretically(理论上地)possible.”
“Most people know that things like a good diet matter and that smoking isn't good for them, ” Susan Jebb said.“We need to work on providing people with much more practical support to help them change.”
Which of the following DOESN'T belong to the four healthy habits?
A.Eat five servings of fruits and vegetables a day. |
B.Do proper exercise in the morning every day. |
C.Drinking alcohol in the proper amount every day. |
D.Having a cigarette before going to bed every day. |
We can learn from the passage that .
A.Susan Jebb did not take part in the study. |
B.the study observed people as well as tested specific changes. |
C.there's no need for people under 45 to adopt these good habits. |
D.only those from first class can benefit from these healthy behaviors. |
What can be inferred from the passage?
A.All the people are well aware of the harm of their bad habits. |
B.People aged 45 to 70 have bad habits in the United Kingdom. |
C.Governments should take measures to help people change their bad habits. |
D.People have adopted the four healthy habits after knowing they're good. |
What would be the best title for this passage?
A.Smoking and Drinking Cuts You 14 Years |
B.How to Live a Much Healthier Life |
C.How to Make Your Life Longer Than Others |
D.Healthy Habits May Give Extra 14 Years |
From the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great effort into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.
The international space station (ISS) is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.
As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone,and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone’s effort and will benefit everyone.
Led by the U.S. and Russia, the ISS is a joint project between six space agencies involving 16 countries. Called the greatest achievement in human cooperation, the ISS has come to the end of a ten-year’s hard work in construction. China has applied for participation in (taking part in) the project many times. Unfortunately all the applications were rejected, which drove China onto the path of independent development. As the Long March Ⅱ-F/T1 carrier rocket blasted off (leave the ground) and successfully carried the Tiangong-1 into space on September 29, 2011, China takes a big step toward its Space Station Era.
Some West media suggested that the successful launch of Tiangong-1 would disturb the balance of global space power, raising concerns (关注) about “China threat”. China’s space project is not designed for military (军事的) purpose but for developing space technology to explore space resources and make use of them for mankind’s well-being.
From Paragraph 2 we learn that ________.
A.the necessity of building the international space station is not realized now |
B.many experiments have been done in the international space station |
C.the international space station is necessary for people to explore space more |
D.people have traveled to Mars from the international space station |
Which of the following is NOT a reason for countries’ cooperation in building the international space station?
A.That it requires a lot of money. |
B.That it needs everyone’s effort. |
C.That it will benefit every participating country. |
D.That it is too far away from the earth. |
The underlined word “aggregated” in Paragraph 3 can be replaced by “________”.
A.united | B.scolded | C.allowed | D.forbade |
China wants to build its space station in order to __________.
A.break the balance of global space power |
B.show that China can build space station alone |
C.raise international concerns about “China threat” |
D.make use of space peacefully for mankind’s well-being |
At Priya's wedding party, her mother gave her a newly opened bankbook and said, "Priya, keep it as a 21 of your marriage life.

GUATEMALA CITY(Reuters)— A fish that lives in mangrove swamps(红树沼泽)across the Americas can live out of water for months at a time, similar to how animals adapted(适应)to land millions of years ago, a new study shows.
The Mangrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.
The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out.” Taylor told Reuters in neighboring Guatemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡)from water onto land,” Wright said.
The Mangrove Rivulus is a type of fish that__________.
A.like eating nuts |
B.prefers living in dry places |
C.is the longest living fish on earth |
D.can stay alive for two months out of water |
Who will write up a report on Mangrove Rivulus?
A.Patricia Wright | B.Researchers in Guatemala |
C.Scientists from Belize | D.Scott Taylor |
According to the text, lungfish can__________.
A.breathe through its skin |
B.move freely on dry land |
C.remain alive out of water |
D.be as active on land as in waster |
What can we say about the discovery of Mangrove Rivulus?
A.It was made quite by accident |
B.It was based on a lab test of sea life |
C.It was supported by an American magazine |
D.It was helped by Patricia Wright |
The story happened on a hot heavy rainy day.
After class, I took a few bottles to go and 36 some water from the water room. Oh! There were so many people! I had to wait 37 the rain. My hair didn't get wet because I wore a hat, but my clothes 38 .
When at last it was my 39 , I filled the bottles as quickly as possible. I began making my way back when I saw a boy 40 towards me. He 41 two umbrellas in his hand. He shouted hello and as he came 42 , I recognized that it was Tom.
He 43 my classmate for nearly three years, but we never 44 more than ten sentences. He was silent, but I liked talking. We were quite 45 people and had nothing in common. I didn't 46 him and even didn't want to see him.
"Hey! What's wrong?" His words 47 me out of my thought. "I saw you 48 in the rain, so I brought you this umbrella. But it seems a little 49 , your clothes are already wet,"
On hearing this, I was so 50 that I couldn't say a single word.
"Don't just stand there. Let's go!" He said and held the umbrella for me. We walked towards 51 and this time we talked 52 .
"I know you don't like me, but I want to 53 with you." he said, "You may think I am silent, but it is because I can't find the right 54 to say."
The rain finally stopped and we saw a rainbow in the blue sky. I said to myself, "It is wrong to 55 someone only by his appearance.

As the summer time approaches, more and more commercials and advertisements can be seen on the mass media encouraging students to join English study tours abroad. The purpose of these tours is to provide students with an opportunity to learn English in a native speaking environment and use English in real situations. Parents always believe that their children will automatically speak good English after attending these study tours. However, for me, as an English major and former participant of many English study tours, I find these summer tours ineffective.
Parents who send their children abroad for a summer to study English usually believe that the native speaking environment, including the courses, teachers, and host families, can help their children to learn English better. This might be true if the students really study hard and they really get an all-English environment. But the fact is that, most of the time, the tour part is more important than the study part. Although these tours take place in foreign countries, students are rarely exposed in an all-English environment. You will find that, in the morning classes, Taiwanese students would like to stick together and speak Chinese with each other, even though there are some students from other countries. In the afternoon, the students go on a sightseeing excursion with their companions from Taiwan; they speak Chinese of course. In the evening, when students return to the host families, they would stay in their room and share the day with their roommate, another Taiwanese student. People who speak the same language with you is like a log(原木)in the ocean when living in a foreign country where you can not express yourself well, so that you would naturally stick with them. This is especially true with children.
Another unrealistic expectation parents have for these tours is that the experience of living abroad can make their children more independent and mature. However, maturity does not come overnight. It takes time and practice. The most important of all is that they need a good mentor(顾问). None of these exist in the study tours.
Which of the following is the most important thing for children who study in an English environment according to the writer?
A.Host families. | B.Hard work. | C.Courses. | D.Teachers. |
The underlined word “mature” in the last paragraph probably means .
A.active | B.free | C.outgoing | D.grown-up |
What’s the author’s attitude towards the English study tours abroad?
A.Doubtful. | B.Negative. | C.Positive. | D.Neutral. |
Last Friday my brother and I were driving home and had a fun conversation. So absorbed in our talk, my brother took a wrong turn.
Unfortunately, the wrong turn took us towards a 31 , and we had no way to turn 32 . __33 my brother paid the bridge fee and drove on. He was greatly 34 by his mistake and the needless 35 of $4.
We eventually reached an exit, and as we took it, my brother noticed a young fellow 36 over to the side. He came out of his car and tried to 37 someone. I was busy trying to 38 which way we would go next, but my brother stopped and asked the guy if he needed any 39 And he did. He had a flat tire and needed a tool to get it off.
My brother gave him a wrench(扳手), and then helped him 40 the flat. The young man said that this had been a 41 week for him: earlier he had gotten into a minor car 42 , and now this tire was flat on his way home from work. But he called us “a breath of fresh air’’ and kept 43 us because he really would have been 44 if we hadn’t come along.
After we had finished the job, he thanked us again and pulled out $20 to give us. “No,” my brother said. “We were never 45 to even get on that bridge. We took a wrong turn. But now we know 46 we did. It was to help you. Thank you for turning our mistake into a(n) 47 to serve.”
What I loved most was 48 my brother throughout this process. He was able to turn his mistake into 49 energy to help others even in a negative situation, which could only come from a calm mind and an open 50 .
