Are you carrying too much on your back at school? You're not alone. Back experts in the USA were worried that young students are having back and neck problems because they are carrying too much in their backpacks （schoolbags）.
"It hurts my back when I run，" said Beeline Reyes, a student in Virginia. "It's hard to get up the stairs with my backpack because it's too heavy. "
Students have to carry heavy backpacks on their backs for a whole week's study. Beeline is one of them. They have regular back-packs with two straps （带子）to carry them, but a number of students with heavy loads have switched to rolling backpacks. The backpacks have wheels and can roll on the ground.
Shirley Park's backpack weighs 10 kilos, and she said，"I'll change to a rolling backpack because I am starting to have back pain. "
How much is too much? Experts say that students should carry no more than 10 to 15 percent of their own body weight. A few students have had a good idea to lighten the load ： Less homework.
Doctor's suggestions ：
•Lighten the load. Take home only the books the students need that night.
•Wide straps are better. They can send out weight over your shoulders and be sure to wear backpacks with two straps.
•The heaviest things should be packed closest to the back.
•Bend （弯曲）both knees when you pick up the pack, don't just bend the waist（腰）.The main idea of the text is __________.
| A．the problems made by rolling backpacks |

Air travel is such an everyday experience these days that we are not surprised when we read about a politician having talks with the Japanese Prime Minister one day, attending a meeting in Australia the following morning and having to be off at midday to sign a trade agreement in Hong Kong. But frequent long-distance flying can be so tiring that the traveler begins to feel his brain is in one country, his digestion in another and his powers of concentration nowhere---in short, he hardly knows where he is.
Air travel is so quick nowadays that we can leave London after breakfast and be in New York in eight hours, yet what really disturbs us most is that when we arrive it is lunch time while we have already had lunch on the plane and are expecting dinner.

Our eating habits are very important for good health and a strong body. There are times when most of us would have sweets and ice-cream rather than eat meat and rice. Sweets and ice-cream are not bad for the stomach if we eat at the end of a meal. If we drink beer at meals, it may take away our appetite. It is important for us to eat our meal at the same time each day. When we feel hungry, it is a sign that our body needs food. When we feel angry or excited, we may not want to eat. A long time ago, in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not swallow the bread, it was a sign that he was not telling the truth. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth.

After a day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs your eyeballs begin to move quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.A good title for this passage is _______.

Miss Popular
I was awkward in middle school: bony and athletic, with a high grade in science and a low one in self-esteem. Though I had a few friends, I wasn’t popular. I was picked last in football and I sometimes ate lunch by myself.
I remember the day Brittany came to our school. Her teeth were crooked(歪斜的), and she was a little overweight. Not that this mattered though, because she walked around like she was better than all of us. She was outspoken and incredibly frightening, making people lose confidence.
Around Brittany, I tried my best to go unnoticed. Standing out or stealing her spotlight could only result in one thing: conflict. Brittany was always the first girl picked for teams; I was lucky if I was picked at all. I was thrown the ball while she stood with the quarterback, chatting about the last party she’d gone to. I had never been to a party before or kissed a boy.
One day, a classmate asked me to the school dance. I was flattered. Then Brittany told me during science class that she had persuaded him to invite me. She asked in front of everyone, “Why would anyone even want you?” I went home and cried.
Although she was seemingly perfect in everyone’s eyes, I wanted to be everything that she wasn’t and yet a million times more perfect. Brittany was so frightening and violent, but I wanted to be calm and not at all aggressive.
I found Brittany’s online profile a few weeks ago. She still had the same chubby(圆胖脸) face and mocking（嘲笑的）simile, and had posted half-naked pictures of herself. But as I read on, I realized that Brittany had died in a drunken driving accident a year ago. She had been 16 and pregnant at the time. Suddenly my view of Brittany changed from a bad influence into a struggling little girl whose life was taken before she could understand right from wrong. My experience with Brittany taught me that though we are all innocent in our youth, the choices we make will have great effects on us forever. I will always remember Brittany as that loud, overconfident girl. As part of that shy insecure person I used to be will always keep me modest.From the first three passages we can conclude that .
| A．the author was trying to avoid conflict with Brittany |

| A．She didn’t mean to hurt the author. |
| B．She took delight in hurting others. |
| C．Her confidence came from her popularity. |
| D．Her overweight made her more outspoken. |
According to the passage we can learn that the author .
| A．was afraid of Brittany and followed her lead |
| B．saw the influence that low self-esteem can have |
| C．was determined to be better than Brittany |
| D．knew she was quietly different from Brittany |
The last passage is meant to .
| A．tell us the reason for Brittany’s death |
| B．present the changed attitude to Brittany |
| C．show the influences of the youth |
| D．stress the importance of behaviors |
