Want to lose weight? Try eating. That’s one of the ways being developed by scientists experimenting with foods that trick the body into feeling full.
At he Institute of Food Research in Norwich, England, food expert Peter Wilde and his colleagues are developing foods that slow down the digestive system, which then sends a signal to the brain that stops appetite. “That fools you into thinking you’ve eaten far too much when you really haven’t,” said Wilde. From his studies on fat digestion, he said it should be possible to make foods, from bread to yoghurt, that make it easier to diet. While the research is still in its early stages, Wilde’s approach to controlling appetite is one that some doctors say could be a key to solving the problem of obesity.
“Being able to switch off appetite would be a big help for people having trouble losing weight,” said Steve Bloom, a professor of investigative medicine at London’s Imperial College, who is not connected to Wilde’s research. Bloom said that regulating appetite through foods is theoretically possible. But Bloom warned that controlling appetite may be very challenging. “The body has lots of things to prevent its regulatory systems from being tricked,” he said.
Wilde’s research makes use of the body’s ways of digesting fat. Fat normally gets broken down in the first part of the small intestines (肠道). When you eat a high-fat meal, however, the body can only digest the fat entirely further down in the intestines, which then causes the body to produce a kind of chemical to stop the appetite.
Wilde’s approach copies what happens with a high-fat meal. He coats fat droplets (滴) in foods with modified proteins from plants, so it takes longer for the chemical that breaks down fat to reach it. That means that the fat isn’t digested until it hits the far reaches of the intestines. At that point, intestinal cells send a signal telling the brain it’s full. Even though the body hasn’t had a high-fat meal, it stops the appetite as if it has. If the fat had been digested earlier in the intestines, no such signal would be sent.

A. Eat more bread and yoghurt.                    B. Trick the body by eating nothing.

52. The underlined word “obesity” in Para. 2 most probably means “________”.
A. being too fat                            B. eating too much food       
C. stopping appetite                D. being unhealthy
53. What can be inferred about Professor Bloom’s opinion towards Wilde’s approach?
A. It won’t work since the body’s regulatory systems will never be tricked.
B. It is sure to switch off the appetite of people with a weight problem.
C. It sounds terrible because regulating appetite through foods is not practical at all.
D. It’s no that easy to trick the body so more research should be done.
54. Which of the following is TRUE about Wilde’s approach?
A. A kind of chemical is added to make a high-fat meal less fatty.
B. Fat is digested earlier and the body sends a signal telling the brain it’s full.
C. Fat won’t get broken down in the first part of the small intestines.
D. The chemical that breaks down fat will not reach the fat.
55. The passage is written to ________.

Here are six steps to better studying.
Pay attention in class
Do you have trouble paying attention in class? Are you sitting next to a loud person? Tell your teacher or parents about any problem that is preventing you from paying attention.
Take good notes
Write down facts that your teacher mentions or writes on the board. Try to use good handwriting so you can read your notes later. It’s a good idea to keep your notes organized by subject.
Plan ahead for tests and projects
Waiting until Thursday night to study for Friday’s test will make it hard to do your best. One of the best ways to make sure that doesn’t happen is to plan ahead. Write down your test dates. You can then plan how much to do after school each day, and how much time to spend on each topic.
Break it up
Ask for help
You can’t study effectively if you don’t understand the material. Be sure to ask your teacher for help. If you’re at home when the confusion occurs, your morn or dad might be able to help.
Sleep tight
So the test is tomorrow and you’ve followed your study plan—but suddenly you can’t remember anything! Don’t panic. Your brain needs time to digest all the information you’ve given it. Try to get a good night’s sleep and you’ll be surprised by what comes back to you in the morning.

I was in a crowded local in Mumbai. I was lucky to find a seat as I had got in at the first station. Soon, the seats were all  21  ,and most people had to stand.
In the middle of all this, I saw a girl about 10 years old. It was   22  that she was used to the crowd and the pushing, because she would silently change  23  to be just a little bit more comfortable. I felt a little sad sitting there  24  her standing nearby.
It struck me that this is the time to  25  an act of kindness. However, I had to overcome some internal barriers before I   26  an act of kindness. “World I look foolish trying to help her?” I wondered.

And then, I began to think—“Why hadn’t I offered it to her even  34  ?” “What was stopping me?” A complete about-face came from my previous thoughts.
35  , the gift of gratitude she had given me was far more that the ‘scat’ I had offered her! It was  36  to say who was doing the giving. She was so considerate as she sat at the sat at the very edge of my knee,   37  half her weight so as not to make my legs hurt. I told her that she could sit comfortably, and I wouldn’t   38  . I got one more pure expression of   39  ! And luckily, I was in the window seat, so the little grill had fun  40  the sights form the window! This simple give and take made the day beautiful!

Having finished her homework, Ma Li wants some music for relaxation^①. As usual, she starts her computer and goes to Baidu.com to download music files. But this time she is surprised when an announcement about protecting songs’ copyright bursts onto the screen. The age of free music and movie downloads may have come to an end as Web companies like Baidu are accused of pirating copyright. Lawsuits^② have been filed against four websites offering free downloads. In September 2005, a Beijing court ordered Baidu to pay recording company Shanghai Push compensation for their losses. Baidu was also told to block the links to the pirated music on the website. This caused a heated discussion on Interact file sharing.

“Baidu’s defeat in the lawsuit shows it is not right to get copyrighted songs without paying. Downloaders may face lawsuits or fines,” said an official.

Like many teens, Huang Ruoru, an 18-year-old girl from Puning in Guangdong Province, doesn’t think that getting music from websites is wrong. She always shares her favourite songs downloaded from Baidu with her friends. When told about the lawsuit, she began to feel a little guilty about obtaining others’ work without paying.

However, other teenagers have different ideas. Wang Yafei, a Senior 2 girl from Jinan, Shandong Province pointed out that file sharing is a good way to promote pop singers. “If I download a song and really like it, I will buy the CD,” she said. “So what the recording companies really should concentrate on is improving their music, rather than pursuing^③ file-sharers.”

relaxation  n. 娱乐
