Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates (碳水化合物)一all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a high一protein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet.
Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.
It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”According to Wycherley’s analysis, dieters should take in more ______.
| A．fat | B．carbohydrates | C．protein | D．calories |
What can we learn from the studies?
| A．It bums more calories to deal with carbohydrates. |
| B．Protein helps keep muscle mass which bums calories. |
| C．Vegetables contain more protein than animals. |
| D．No more calories are burned while the body is resting. |
What is Levine’s attitude towards the conclusion of the studies?
| A．Doubtful. | B．Supportive. | C．Curious. | D．Agreeable. |
第三部分：阅读理解（共20小题；每小题2分，满分40分）
阅读下列短文，从各篇短文后所给各题的四个选项（A、B、C和D）中，选出最佳选项。
It was shortly before midnight, and Dr Patricia was getting ready for bed. The phone rang on the end of the line was a woman about to break a promise.
The woman was her mother’s neighbor. Flora Harris had made the neighbor swear she wouldn’t tell her daughter she’d had a heart attack and was in the hospital, for fear her daughter would worry. The neighbor wisely decided to disobey orders.
Harris desperately wanted to get to the hospital immediately, but she couldn’t. She lives in Washingt
on, D. C, and her mother lives in California.
For the past year a half, Harris has gone to Los Angeles every other month to take care of her mother. Flora Harris takes care of her husband, James, who’s 91 and has Alzheimer’s disease. They live in their own home, and a caregiver comes to help them a few hours a day.
Harris is one of many Americans facing the heartache of how to take care of aging parents from afar. She’s often worried, not to mention exrtemely busy with a demanding job, two teenage daughters and the frequent trips to California.
In some ways, Harris is lucky. She has the resources to make the trips to Los Angeles. Plus, Harris is a doctor who treats the elderly.
“But it’s still tough,” she says. “I can foresee what the next few years are going to look like, and it’s not a pretty picture. My father’s going to need diapers (尿布). There will come a time when he won’t recognize me and he’s easily excited. I worry he’s going to be violent and hurt my mother.”

I shall never forget the night, a few years ago, when Marion J. Douglas was a student in one of my calsses. (I have not used his real name for personal reasons. As he requested.) But here is his real story as he told it before one of our adult – education classes. He told us how tragedy had struck at his home, not once, but twice. The first time he had lost his five-old daughter, a child he adored. He and his wife thought they couldn’t bear that first loss; but, as he said:“Ten months later, God gave us another little girl and she died in five days.”
This double bereavement was almost too much to bear. “I couldn’t take it,” this father told us. “I couldn’t sleep, I couldn’t eat, I couldn’t rest or relax. My nerves were entirely shaken and my confidence gone.” At last he went to doctors; one recommended sleeping pills and another recommended a trip. He tried both, but neither helped. He said:“My body felt as if it was surrounded in a vice(大钳子), and the jaws of the vice were being drawn tighter and tighter.” The tension of grief(悲伤)——if you have ever been paralyzed(使瘫痪)by sorrow, you know what he meant.
But thank God, I had one child left ——a four —year— old son. He gave me the solution to my problem. One afternoon as I sat around feeling sorry for myself, he asked; ‘Daddy, will you build a boat for me?’ I was in no mood to build a boat; in fact, I was in no mood to do anything. But my son is a persistent little fellow! I had to give in.
Building that toy boat took me about three hours. By the time it was finished, I realized that those three hours spent building that boat were first hours of mental relaxation and peace that I had had in months! I realized that it is difficult to worry while you are busy doing something that requires planning and thinking. In my case, building the boat had knocked worry out of the ring. So I determined to keep busy.
The following night, I went from room to room in the house, making a list of jobs that ought to be done. Scores of items needed to be repaired: bookcase, stair steps, storm windows, window-shades, locks, leaky taps. Amazing as it seems, in the course of two weeks I had made a list of 242 items that needed attention.
“During the last two years I have completed most of them. I am busy now that I have no time for worry.”
No time for worry! That is exactly what Winston Churchill said when he was working eighteen hours a day at the height of the war. When he was asked if he worried about his huge responsibilities, he said :“I am too busy. I have no time for worry.”

on made a list of over 200 items that needed to be repaired because .

So much to do, so little time．So much information, so little time to read ．In this age there is more information than ever before．There is not enough time to read everything we want to read．However, you can take in and understand more information in shorter time through speed-reading．This article will not make you read 3 000 words per minute, but it will show you how to increase your speed greatly．You will also learn the basic techniques of speed reading, along with the dos and don'ts of speed-reading．
When you first learned to read, you would say the word out loud and sound it out．Then you might whisper the word because people can become annoyed when you read aloud．The stage you are now at is saying the word in your head．Most people tend to read this way．Saying the word in your head will cut your reading speed tremendou
sly (极大的)．
How do you calculate your reading speed? The speed is measured by how many words per minute you can read．Getsome reading material, preferably a book．Find out
how many words are on the page．Time yourself one minute．Start your timer and start reading．When the timer sounds, stop at once．If you counted 500 words on the page and you read half of the page, then you are probably reading at 250 words per minute．
The first thing about speed-reading is looking at the word and recognizing it．Don't say the word in your mind, just look at it and recognize its appearance．Later you will recognize groups of four words or more to increase your speed．This is the first and most important step in speed-reading．
The next step is technique．As with any other skill, speed-reading requires technique．You should first be sitting up straight with your book on a horizontal (水平的) surface, such as a table or desk．Next, should be able to see the entire page．This is necessary if you want to recognize clumps of words．Lastly, you should be focused．It's hard to read a lot of noise．Find a quiet place to read．This will help your understand of the text．You need something to guide your eyes while reading．Then right, you should use your hand, Remember when you were little, you would read using your finger．That is a great technique, only now you're using your hand to underline each line．Move your finger smoothly across page．No need to go rush , start our slow．Keep your eyes focused on words as you recognize them while using your hand as a guide．This will increase you speed．
The third step is practice．Practice makes perfect．Set time intervals(间歇)．Read using different techniques, but make sure you understand what you're reading．

Here are a few tips we’ve put together to help you learn English well .
Speak , speak , speak !
Practise speaking as often as you can —even speaking to yourself is good practice .
Try recording yourself whenever you can . Compare your pronunciation with the master version （版本）, see how you can do better and have another go . If you do this several times , you will find that each version is better than the last .
Why not learn with someone else ?
It helps if you can learn with someone else . If you can persuade a friend or family member to study with you , it will make you keep working .
Don’t get stuck by a word you don’t know .
Practise improvising （即兴的）ways of getting your meaning across when speaking spontaneously （本能地）, even if you don’t know the exact words or phrases . Think of things you might want to say whenever you
have spare time . Use facial expressions , hand movements , anything to get your meaning across .
Language learning is also about intuition （直觉）.
Guesswork is an important way to learn 
a new language . When listening to recorded materi
al , you aren’t 
expected to understand everything first time round . If you play the same piece several times , you will most probably understand something new each time .
Build up your vocabulary .
A wide vocabulary is the key to successful language learning but don’t try to learn too much at once. It’s best to study frequently , for short periods of time . Take at most six or seven items of vocabulary and learn them .Put them into sentences to fix them in your mind , then come back to them later .
And above all , have fun !
