Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圓木),and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.
【小題1】Scientists think animals can help people to do something _____ .
A.if they know they will get food after doing something.
B.because animals are so clever.
C.if they know the work is easy enough
D.because most animals are friendly to man
【小題2】_______ can do some heavy work because they are so strong.
A.TigersB.ElephantsC.MonkeysD.Dogs
【小題3】What does the underlined word “apes”   mean in Chinese?
A.獵豹B.猿猴C.孔雀D.獅子
【小題4】Scientists are planning to make big monkeys to________.
A.make trainsB.carry logsC.drive trainsD.work at school
【小題5】If we teach animals carefully, ________.
A.some animals can do the same things as man does.
B.all the animals can work for us.
C.many animals can do all the work as we do.
D.we may get many animals to work without giving them food.

A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸張), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (開夜車). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.
Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.
【小題1】What does the underlined sentence “it’s close to the truth” mean?
A.It doesn’t tell the truth. B.It is quite true.
C.It is impossible.D.I don’t think it’s right.
【小題2】Why do most of the teens have to stay up late?
A.They play computer games.B.They watch videos late.
C.They have to do a lot of housework.D.They have to do a lot of homework.
【小題3】When do students in most American high schools have to get up?
A.At 7:30 am.B.At 6:00 am.C.At 9:00 am.D.At about 7:00 am.
【小題4】Which of the following is TRUE according to the reading?
A.The writer usually stays up past 1:30 am.
B.The writer usually goes to bed around midnight.
C.The writer usually does a survey.
D.Many American students don’t get enough sleep, so they can have high grades.
【小題5】What’s the main idea of the passage?
A.Something has to be done to solve the problem of students’ lack of sleep.
B.Many American high school students are sleepy in class.
C.Many kids have too much homework to do.
D.Students can’t play computer games.

Do you have any foreign friends? Do you know their characteristics(特征)?
The Germans are very quiet and they always keep calm. They don’t like to speak more words. They look very serious. They like different kinds of amusements. The Germans are very hard—working. They like tidiness, especially the women, who always keep their home clean.
In some ways, the Englishmen look the same as the Germans. They are very quiet and never talk too much with the strangers. They are really polite, so we often hear they say “Thank you.” Or “Sorry.” The gentlemen are also the Englishmen.
The French’s holidays are very long. They like traveling and usually spend their long time staying in other countries. The Frenchmen are more outgoing than the Germans. It is very easy to make friends with them.
Compared to the Frenchmen, the Americans are more outgoing. And they are even opener than all of the Europeans. They don’t like to depend on others. So it is very common that the students do part-time jobs in their free time. And in Americans’ eyes, success is an important part in their life.

Do you know that it is your own immune system working against the virus that makes you uncomfortable when getting a cold, but not the virus itself? So when you have got a strong immune system and the virus is strong enough too, you will possibly get terrible cold symptoms( 癥狀) ?
Vitamin C won't stop a cold
It is claimed that Vitamin C helps by increasing white blood cells. However, many tests have shown that it does not prevent colds. At best, it only slightly reduces the rime of symptoms.
Staying indoors won't protect you
One of the most likely sources of cold viruses is your computer mouse or desk. A study of the cold virus in offices found that 47% of desktops, 46% of computer mice and 45% of telephones had cold viruses on them.
Wrapping up warm won't protect you
Colds are more common in autumn and winter. That's because the cool, wet and cold weather drives people indoors, where viruses may more easily jump from one person to another. And the distinct peak in colds(感冒高峰) is in September and early January, which is likely due to the return of students to schools and colleges after the summer and winter vacation.
Old granny's chicken soup is right
Granny's chicken soup is an old cure for colds since a long time ago. Scientists say it is true. Chicken soup does help cure a cold. Many canned soups are just efficient as homemade ones.
【小題1】 It is ______ that makes you uncomfortable when getting a cold.

A very old lady won a million dollars in a lottery(彩票). Her son and her husband heard the news on the radio.
“How are we going to tell your mother?” the man asked. “The news might kill her!”
“That’s true,” the son said. “Perhaps we’d better speak to her doctor about it. He’ll know how to bring her the news gently.”
They told the old lady’s doctor about this.
“I’m glad you told me, ” he said “A shock(震驚), even a happy one, could give her a heart attack, leave it to me. I’ll find a way of bringing the news to her.”
The doctor thought about the problem for several days, then decided what he would say.
He called on the old lady and sat by her. He took her hand in his.
“Let’s play a game, my dear,” he said. “‘Let’s pretend(假裝)’ game.”
“Oh, yes, ” the old lady said. “I love ‘Let’s pretend’ game.”
“Good, I’ll ask you a question first, ” the doctor said, “Then you can ask me one.”
He pretended to think for a few minutes. Then he said, “Tell me, what would you do if you won a million dollars in the lottery?”
