　　Small-class teaching used to be accepted only in universities in China. But it has been very 1 in all schools abroad. Interestingly, it seem that it is finding 2 way into the primary schools(小学)in Shanghai.

　　Recently, 12 schools 3 Hetian Road Primary School held small-class lessons.

　　One day I 4 the classroom of class 4, Grade 1 of Siping Road Primary School, I found that they were 5 a Chinese lesson with the topic(话题) of " 6 ".The 24 pupils of the class were divided into six 7 .They were discussing the question 8 by teacher: Draw the scenery (风景) 9 in the spring. In a moment, four 10 of drawing were hung before the 11 .Then the children were 12 to explain the drawing in their own 13 :"The sun is smiling"; The little fish 14 out of the river to 15 the red flowers or green leaves in the spring"; "the little bird is playing a 16 in the sky"; "The grass is dancing by the river"…

　　The new teaching 17 greatly helped develop every child's 18 ability(能力) and thirst for 19 .

　　When asked about the good results brought about by the small-class teaching , Mr Yu, headmaster of Siping Road Primary School, said that new way of teaching 20 .It can help puplis work out problems on their own. 22 ,a teacher may have to pay more attention to each 23 ,even to some shy ones who are often neglected (忽视) by the teachers in a 24 class. This means that teachers should know each student quite well, Yu said.

　　It is said that, in the near future, the small-class teaching method will 25 to other primary schools in Shanghai.

The Internet will open up new vistas (前景), create the global village——you can make new friends all around the world. That, at least, is what it promised us. The difficulty is that it did not take the human mind into account. The reality is that we cannot keep relationships with more than a limited number of people. No matter how hard the Internet tries to put you in communication, its best efforts will be defeated by your mind.

The problem is twofold（双重的）. First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest in then. We invest a lot in a small number of people and then distribute what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline until eventually it dies into “someone I once knew”.

This is not, of course, to say that the Internet doesn’t serve a socially valuable function. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.

In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see them, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The Internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.

1.The number of friends we can keep relationships with is decided by__________.

A. the Internet   B. the time we have  C. the place we live  D. the mind

2.The underlined word “engagement” in the second paragraph probably means “__________”.

　A. appointment   B. connection   C. interview    D. agreement

3.The author holds the view that___________.

  A. the Internet helps to keep in touch with friends far away

B. the Internet determines the quality of social relationships

C. the Internet greatly increases the size of social circles

D. the Internet is of no value in social communication

4.What will the author encourage us to do?

　A. To keep in touch with old friends when we have moved away.

　B. To chat with friends often on the Internet.

　C. To make more new friends face to face.

　D. To stop using the Internet to make new friends.

5.What is the author’s attitude towards the use of the Internet to strengthen relationships?

　A. He thinks it useless           B. He is hopeful of it.

　C. He approves of it.            D. He doubts it.

Fish Ears Tell Fish Tales

　 Fish have ears. Really. They’re quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths (耳石).

　 As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate (碳酸钙). By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish’s age, just like the growth rings of a tree.

　 Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They’re examining the chemical elements (元素) of each otolith ring.

　 The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring.

　 Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history.

　 In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles.

　 This is important to managers in the fish industry, who know nearly nothing about the whereabouts of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears.

What can we learn about fish ears from the text?

　A. They are small soft rings.

　B. They are not seen from the outside.

　C. They are openings only on food fish.

　D. They are not used to receive sound.

Why does the writer compare the fish to trees?

　A. Trees gain a growth ring each day.

　B. Trees also have otoliths.

　C. Their growth rings are very small.

　D. They both have growth rings.

Why is it important to study the chemistry of otolith rings?

　A. The elements of the otoliths can tell the history of the sea.

　B. Chemical contents of otoliths can tell how fast fish can swim.

　C. We can know more about fish and their living environment.

　D. Scientists can know exactly how old a fish is.

How would you understand “fish scientists are now lending their ears”?

　A. They are very interested in Thorrold’s research findings.

　B. They want to know where they can find fish.

　C. They lend their fish for chemical studies.

　D. They wonder if Thorrold can find growth rings from their ears.
