  • 第5题:

    C

    Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin. In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young. Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws. During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

    63.What is the text mainly about?

    A.Hoatzins in dry and rainy seasons.

    B.The relatives and enemies of hoatzins.

    C.Primitive birds and hoatzins of the Amazon.

    D.The appearance and living habits of hoatzins.

    题目要求:  In this part of the test, the examiner reads out a scenario and gives you some prompt material in the form of pictures or words. You have 30 seconds to look at the task prompt, an example of which is below, and then about two minutes to discuss the scenario with your partner. After that, the examiner will ask you more questions related to the topic.Practice 1  For two or three candidates  I’m going to describe a situation.  Your company is going to rent offices. Talk together about the topics you could include when you decide to rent offices. Decide which 3 topics you think are most important.  * three minutes for groups of three candidates  Prompt material  Topics to include  ●Location  ●Cost  ●Transportation  Follow-up questions:  (l) Are facilities important when renting office? (Why? / Why not? )  (2) Do you think security system should be safe? (Why? / Why not? )  (3) Why do big companies also choose big office buildings? (Why? / Why not? )

    正确答案: 【参考范例】
    A: You see. Our company is thinking about renting offices. What do you think should be taken into consideration before making a decision?
    B: I think first we should consider the location. The offices should be better in the commercial area of the city, for it is easier for our company to be found and to exchange information with other companies in the area.
    A: You are right. A good location will allow a company to do business more efficiently.
    B: Moreover, I think cost is another factor that we need to consider. If the location is in the commercial area, the cost of renting may be very high.
    A: That’s true. If the cost of the location is too high, it will certainly exceed the company’s budget. But if the price is reasonable, we can take it. After all, the cost should be on the average of the city.
    B: Absolutely. What about the transportation?
    A: The location should have good transport connection, and the transportation should be very convenient, linking the bus stop, subway, high way, the airport or the harbor. Then, the customers can get to our company without too much difficulty. .
