After a busy 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 day. The rest that you get while sleeping makes it possible for 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 body relaxes little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts(变换) back and forth from one level to the other.
Although your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more 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(建议) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
49. During REM, ______
A. you move restless B. you start dreaming
C. your mind stops working D. your eyeballs move quickly
50. A good title for this text might be_________
A. Dreams B. Sleep C. Good Health D. Work and Rest
Compared to the other parts of the body, our ears don’t ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones.
Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from your parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.
If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life.
So don’t wear your earphones too long. Use them less than one hour a day.
Want sharp hearing? Don’t forget to do the following:
Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs.
When swimming, remember to put earplugs into your ears to stop water from getting in.
Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.
Keep these things in mind! Then you won't be saying "WHAT???" when you are older.Which is the topic paragraph of the article?

Do dogs understand us?
Be careful what you say around your dog. It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also
appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee.
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of ten tests, suggesting that the dog had worked
out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its m
ental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return! From paragraph 2 we know that __.
| A．animals are as clever as human beings |
| B．chimpanzees have very good word-learning skills |
| C．dogs are smarter than parrots and chimpanzees |
| D．dogs have similar learning abilities as 3-year-old children |
Both experiments show that.
| A．Rico is smart enough to get all commands right |
| B．Rico can recognize different things including toys |
| C．Rico has developed the ability of learning mathematics |
| D．Rico won't forget the names of objects once recognizing them |
Which of the following statements is true?
| A．Rico has a better memory partly because of its proper early training. |
| B．The purpose of the experiments is to show the border collie's mental abilities. |
| C．The border collie is world-famous for recognizing objects. |
| D．Rico is born to understand its owner's commands. |
What does the writer want to tell us?
| A．To train your dog. | B．To talk to your dog. |
| C．To be careful with your dog. | D．To be friendly to your dog. |
Parents should stop blaming themselves because there’s not a lot they can do about it. I mean the teenager problem. Whatever you do or however you choose to deal with it, at certain times a wonderful, reasonable and helpful child will turn into a terrible animal.
I’ve seen friends deal with it in all kinds of different ways. One strict mother insisted that her son, right from a child, should stand up whenever anyone entered the room, open doors and shake hands like a gentleman. I saw him last week when I called round. Sprawling himself (懒散地躺) on the sofa in full length, he made no attempt to turn off the loud TV he was watching as I walked in, and his greeting was no more than a quick glance at me. His mother was ashamed. “I don't know what to do with him these days,” she said. “He’s forgotten all the manners we taught him.”
He hasn’t forgotten them. He’s just decided that he’s not going to use them. She confessed (坦白) that she would like to come up behind him and throw him down from the sofa onto the floor.
Another good friend of mine let her two daughters climb all over the furniture, reach across the table, stare at me and say, “I don’t like your dress; it’s ugly.” One of the daughters has recently been driven out of school. The other has left home.
“Where did we go wrong?” her parents are now very sad. Probably nowhere much. At least, no more than the rest of that unfortunate race, parents.This text is most probably written by ______.
| A．a specialist（专家） in teenager studies | B．a headmaster of a middle school |
| C．a parent with teenage children | D．a doctor for mental health problems |
The underlined word “it” in the second paragraph refers to ______.
| A．the change from good to bad that’s seen in a child |
| B．the way that parents often blame themselves |
| C．the opinion that a child has of his parents |
| D．the advice that parents want their children to follow |
From the second example we can infer that the parents of the two daughters __.
| A．pay no attention to them | B．are too busy to look after them |
| C．have come to hate them | D．feel helpless to do much about them |
What is the author’s opinion about the sudden change in teenage children?
| A．Parents have no choice but to try to accept it. |
| B．Parents should pay still some attention to the change. |
| C．Parents should work more closely with school teachers. |
| D．Parents are at fault for the change in their children. |
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, 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 a 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 material, you aren’t expected to understand everything first 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!Why should one have himself recorded when practicing speaking?
| A．To improve his speaking. | B．To record his own progress. |
| C．To encourage others to start. | D．To compare himself with others. |
In the writer’s opinion, which of the following is the most important in leaning English?

Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships do not last very long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend treat you. Learning to be a good friend means learning three rules. Be honest; be generous; be understanding.
Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest you may lose your friends’ trust. Good friends always count on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money on your clothes of course. Instead you have to learn how to share things you enjoy, like your hobbies and your interest. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them you help your friend know you better.
Sooner or later every one needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so you can understand the problem better.
No two friendships are ever exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practise honesty, generosity, and understanding.Some friendships don’t last very long because ____.

| C．as important as money | D．more important than anything else |
The underlined word “generosity” means ___.
