You know that pearls grow inside oysters(牡蠣), but would you ever think to look for diamonds inside an ostrich(鴕鳥)? Well, a hunter once shot
an ostrich and discovered, to his great surprise, that the big bird had swallowed a bunch of diamonds. How could such a strange thing happen?
Like many other birds, the ostrich swallows small stones that stay inside its “gizzard”. The gizzard is a bird’s second stomach. It is where the food is ground up. The small stones help to grind up the food so it can be digested. The small stones do the chewing because birds don’t have teeth. In that case of the ostrich with the diamonds, the bird simply had expensive taste in rocks. It used the diamonds to digest its dinner.
Diamonds and stones aren’t all that an ostrich will swallow. If there are no stones around, it will eat just about anything. Sadly for ostriches in zoos, this can be a fatal h
abit. The tendency to swallow anything it sees has caused the death of many an ostrich. Cruel or careless people often throw things into the bird’s living space. They throw keys, coins, and even large objects such as horseshoes. The ostrich swallows them without hesitation. Coins can be the worst. Inside the ostrich they wear down to a razor-sharp edge. They will cut open the bird’s gizzard from the inside. When one young zoo ostrich died, 484 coins weighing more than eight pounds were found in its gizzard.

Surveys of American teenagers find that about half of them do not get enough sleep on school nights. They get an average of 60 to 90 minutes less than experts say they need.
Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups. Yet many schools start classes as early as seven in the morning.
As a result，many students go to class feeling like Danny，16 years old. He plays two sports，lacrosse and football. He is an active teen—except in the morning. DANNY：“Getting up in the morning is pretty terrible. I’m just very out of it and tired. And through first and second period I can hardly stay awake.”
Michael Breus，a clinical psychologist with a specialty in sleep disorders says：“These aren’t a bunch of lazy kids—although，you know，teenagers can of course be lazy. These are children whose biological rhythms，more times than not，are off.”Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night. He says sleepy teens can experience a form of depression that could have big effects on their general well-being. It can affect not just their ability in the classroom but also on the sports field and on the road because any tired driver is dangerous，especially a teenager with a lack of experience.
So what can schools do about sleepy students？The psychologist says one thing they can do is start classes later in the morning.
Eric Peterson，head of St.George’s School in the northeastern state of Rhode Island，says，“In the end，schools ought to do what’s the right thing for their students，first and foremost.”And he wanted to see if a 30-minute delay would make a difference. It did.
According to the passage，which of the following is the chief cause of sleepy teenagers？
A. Persona haibits. B. Early school hours.
C. Sports activities. D. Too much home work.
According to Michael Breus， .
A. Teenagers are too lazy to get up early for school.
B. Teenagers should change their biological rhythms.
C. Lacking sleep can cause serious problems.
D. Sleepy teenagers shouldn’t drive to school.
What is Eric Peterson’s opinion on the issue？
A. Schools should try their best to help students.
B. Students should adjust to their school’s schedule.
C. Changing school schedule is their last choice.
D. Something has to change at the end of a school day.
What does the underlined word“It”in the last sentence might refer to？
A. St.George School. B. Rhode Island State.
C. Students in St.George School. D. 30-minute delay of school day.
What can you infer might follow the passage immediately？
A. Some positive changes in St.George’s school.
B. Some complaints from teachers and parents.
C. Some tips on how to help students foremost.
D. Some unexpected outcome of the delay.

In the United States, friendship can be close, constant, intense, generous, and real, yet it can fade away in a short time if circumstances(環(huán)境) change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while then no more. If the same two people meet again by chance, even years later, they pick up the friendship where it left out and are delighted.
In the United States, you can feel free to visit people's homes, share their holidays, enjoy their lives without fear that you are taking on a lasting obligation(負(fù)擔(dān)). Do not hesitate to accept hospitality(款待) because you can't give it in return. No one will expect you to do so for they know you are far from home. Americans will enjoy welcoming you and be pleased if you accept their hospitality easily.
Once you arrive there, the welcome will be full, warm and real. Most visitors find themselves readily incited into many homes there. In some countries it is considered inhospitable to entertain at home, offering what is felt as “merely” home cooked food, not “doing something” for your guest. It is felt that restaurant entertaining shows more respect and welcome. Or for various other reasons, such as crowded space, language difficulties, or family custom, outsiders are not invited into homes.
In the United States both methods are used, but it is often considered more friendly to invite a person to one's home than to go to a public place, except in purely business relationships. So, if your host or hostess brings you home, do not feel that you are being shown inferior(低級別的) treatment.
Don't feel neglected if you do not find flowers awaiting you in your hotel room either. Flowers are very expensive there, hotel delivery is uncertain, arrival times are delayed, changed, or canceled－so flowers are not customarily sent as a welcoming touch. Please do not feel unwanted! Outward signs vary in different lands; the inward welcome is what matters, and this will be real.
6. In the United States, you will find friendship ________ if circumstances change.
A. dies suddenly B. comes back
C. disappears gradually D. lasts forever
7. Americans ________ their foreign friends to make a return for their hospitality.
A. ask B. require C. never allow D. don't expect
8. In the United States, giving a dinner party at home is considered________ than in a restaurant.
A. less friendly B. less hospitable C. more friendly D. more popular
9. According to the passage, which of the following is NOT true in the United States?
A. Flowers are not customarily sent as a welcoming touch.
B. Flowers are expensive.
C. Flowers are sometimes signs of outward welcome.
D. Flowers must be sent to guests.
10. Which of the following is the BEST title for this passage?
A. Americans' Hospitality B. Americans' Friendship
C. Americans' Invitation D. Americans' Welcome

If you do not use your arms or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(過錯). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受責(zé)備), and few of us know that it is just his own fault. Have you ever found that some people can't read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
6. The main reason for one is poor memory is that ________.
A. his father or mother may have a poor memory
B. he does not use his arms or legs for some time
C. his memory is not often used
D. he can't read or write
7. If you do not use your arms or legs for some time ________.
A. you can't use them any more
B. they will become stronger
C. they become weak and won't become strong until you use them again
D. they will become neither stronger nor weaker
8. Which of the following is NOT true?
A. Your memory works in the same way as your arms or legs.
B. Your memory, like your arms or legs, becomes weak if you don't give it enough chance for practice.
C. Don't learn how to read and write if you want to have a better memory.
D. A good memory comes from more practice.
9. Some people can't read or write, but they usually have better memories, because ________.
A. they have save much trouble
B. they have saved much time to remember things
C. they have to use their memories all the time
D. they can't write everything in a little notebook
10. Which is the BEST title for this passage?

While getting ready for school today, my 16-year-old daughter came into my room to give me a big hug an

ch you are 39.”
I am so 40 by the capacity of love and understanding that 41 my children. My 15-year-old son asked me last night if there was a(n) 42 for him to get a summer job this year in order to help us to pay our bills. 43, in our area, he must be 16.
44 of my children depend on me so much because I am a 45 parent, but just when I pay the 46 that I will not be able to provide for them, they come up with ways to 47. I completely understand that I will 48 have to find a way to pay th
e bills as I do not want my children to take up anything. But for now the 49 that they have stepped up and 50 to help without anyone asking touches me.
