【题目】Proper diet and regular exercise seem to be the only methods for losing weight.However,the importance of water should be added in the process.While medical science has proven the positive effects of water,most people still do not drink enough each day.
The reason why water is so important for weight loss has something to do with metabolism（新陈代谢）of fat. The liver（肝脏）is in charge of this process when it comes to turning stored fat in-to energy.However,the liver is also responsible for helping the kidneys（肾脏）that need enough water in order to function properly.The liver has to perform all the functions of the kidneys on its own when they are short of water.This means the liver doesn't have enough energy to metabolize fat.So,drinking water allows the kidneys to focus on their job and the liver to focus on its job.
Also,studies have shown that water can make us feel full when drunk before meals.Without even making an effort,most people who drink a glass of water before a meal will eat 33% less.This is due in part to the fact that they simply get fuller quicker because the water is taking up space.The other reason is that the food will expand as soon as it hits the water-filled stomach.
Water is important for every aspect of the health of the human body.By drinking more water and improving the health of the body,weight loss goals can be achieved with greater ease.
【1】Which of the following is not mentioned in the passage as a way to lose weight?
A. Regular exercise. B. Drinking water. C. Balanced diet. D. Medical care.
【2】The liver has to take over the job of the kidneys when .
A. the kidneys are lacking in water B. there is something wrong with the kidneys
C. the liver doesn't supply energy for the kidneys D. there is no fat for the liver to metabolize
【3】Why can we lose weight by drinking water before meals?
A. Because we don't feel thirsty any longer. B. Because we eat much less than normal.
C. Because the water takes up too much space. D. Because the food becomes larger and larger.
【4】Which of the following would be the best title for this passage?
A. The Liver Is Important to the Kidneys. B. How the Digestive System Works.
C. Water for a Healthy Life and Losing Weight. D. Several Tips for Losing Weight.
【答案】
【1】D

I used to be a physician at a hospital. I often treated children who had poisoned by medicine with older family members. The children didn’t know the medicine was danger; they just knew it tasted sweetly. Children easily open the bottle what we now use in China.
Some days before, I talked about medicines with an American. He showed me a sort of plastic bottle. The design was quite simple and I’m sure our Chinese factories can produce these bottles. The top of the bottle can be opened by pressing down on them while turning, which is difficult for most young children to do so, though grown-up can open these bottles very easily. I’m certain that the expense of making such tops would be very small. As a doctor, I’d love to see this doing. And most parents would be grateful.
Sincerely yours

Last summer holiday, I took part in a teaching project and volunteered(teach) in a countryside primary school for two weeks.
When we arrived at the school, though shocked by the poor living conditions, we quickly adapted to the life there. My good friend Tom and I were in charge of the third year students, (consist) of just 18 boys and girls. We not only taught them English and maths, but also organized some after-school (activity) for them. Gradually, I found that many of the students were actually quite 6(talent). But some had to leave school early, which is(large) because their families were under heavy financial pressure, and they had to find a job to support the family.
As well as giving lessons, we also helped set up a reading room in the school students hardly had any access good reading materials except textbooks. With the help of school staff and students, we cleaned out an abandoned classroom. When we placed the books students and teachers in my high school (donate) onto the shelves, I found the students were more than excited and (dive) into reading there.
Two weeks quickly passed and we had to leave. I did not know how much we had actually taught them, but for me I learned a great deal—cherish what I possess and study harder.

【题目】阅读理解How to Fill Your Empty Walls with Beautiful Art
If you've ever stared at an empty wall wondering what to put there, you're not alone. The idea of having the same museum print as everyone else doesn't seem that appealing.
But, many people who may be interested in purchasing art are at a loss on how to start. The amount of time taken to discover art and artists that you truly love, and the expense of purchasing art, keep many people from even considering it.
But now, TurningArt is solving this dilemma(困境). TurningArt is an online subscription(订阅 ) service that allows the average consumer to learn about art and be able to afford to own it. TurningArt offers art-lovers an online gallery of thousands of works, from highly accomplished and successful artists, to view in their homes and eventually buy if they want to.
Here's how it works
Visit TurningArt.com to browse through the work of hundreds of independent artists from across the country. Sorted by style, medium, color, price, artist, or even region, new art is added daily. You're sure to find several things you like.
Then, simply sign up for one of TurningArt's subscription plans. These start at just $10 per month. TurningArt will send you your first piece, framed and ready to hang right out of the box. The piece will not be the original, but rather a museum-quality print produced together with the artist. You can request the next piece at any time. New prints arrive in a mailer that you can use to send back your old prints.
You can enjoy each piece for one, two, or three months—however long you want. And, best of all, you never have to worry about taping, sizing, or centering your new print, because all prints are pre-sized to fit easily into the frame originally sent to you.

【题目】D
Would You Pay To Eat In A Dumpster(垃圾箱)?
Most of us don’t reach for that gnarled(多瘤的) carrot when selecting our produce at the local supermarket. That’s exactly why Americans waste up to 40% of edible food every year. This unbelievable number has sparked the ＂ugly food＂ movement, inspiring many companies to sell ugly fruit and vegetables to consumers, rather than throwing them in the trash.
One San Francisco organization is taking a unique approach. The Salvage Supperclub hosts fancy dinners inside dumpsters where they serve dishes entirely prepared with food that would have otherwise gone to waste.
Josh Treuhaft, founder of these ugly food dinners, originally came up with the idea to bring about the awareness of America’s food waste problem. ＂There is undeveloped potential in their food that for some reason, not to their own fault, is going to waste,＂ he told Seeker’s Laura Ling.
Treuhaft isn’t alone in his effort to reduce America’s food waste. A change.org petition last year called for Whole Foods to become part of the ugly food movement. They sold misshapen fruits and vegetables in Northern California stores.
Selling imperfect produce is still relatively rare right now, which can be partially attributed to a supply issue rather than a lack of willing participants. Raley’s, a Sacramento-based grocery chain, started an ugly food pilot program called ＂Real Good＂, but discontinued it after 90 days saying they had ＂some challenges sourcing the product＂. A grower might have large amounts of ugly produce one year due to terrible weather, but much less the next year if the weather is better. Harvests constantly vary and retailers are more likely to buy ugly produce in large number rather than just a few pounds at a time.
This is why organizations like the Salvage Supperclub are playing an important role in the prevention of food waste. The Salvage Supperclub takes it a step further by not only buying the ugly produce, but turning it into a good dining experience as well.
【题文1】What does the underlined words ＂edible food＂ in Paragraph 1 refer to?
A. Healthy food. B. Expensive food.
C. Food suitable to eat. D. Food grown locally.
【题文2】Why does the Salvage Supperclub have dinners inside the dumpsters?
A. To share their fancy ideas. B. To warn people not to waste.
C. To show waste should be reused. D. To advise people not to throw dumpsters.
【题文3】What’s Josh Treuhaft’s advice to reduce America’s food waste?
A. People should make full use of ugly food.
B. People should join in the ugly food movement.
C. People should be more aware of food shortage.
D. People should develop their potential in producing food.
【题文4】What makes Raley’s stop its ＂Real Good＂ after 90 days of its operation?
A. Lack of sources of product. B. Retailers’ pursuing larger profit.
C. Bad harvests due to bad weather. D. People’s unwillingness to buy imperfect produce.

My grandfather and I enjoy fishing.
One Sunday morning we go fishing at a lake. We took ours fishing poles and headed for the lake. As soon as we arrived, so we dropped the lines into the water. Before waiting for about half an hour, I was beginning to get impatiently. I wanted to give up, and my grandfather told me to wait a little longer. Finally, there were a sudden pull at the pole and fish was caught. Within the next few minute, my grandfather also caught a fish.
Felt hungry, we built a fire by the lake and barbecued the fish. It was delicious.
