Question

【題目】閱讀下面短文，從每題所給的四個選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。
How much do you know about the bird world?
Birds use three gaits: walking, running and hopping．
In walking, the left and the right feet move in turn (輪流)．Each foot is on the ground for more than half the time, so there are more times when both feet are on the ground．In running, each foot is on the ground for less than half the time, and there are more times when both feet are off the ground．In hopping, the feet move almost at the same time．This means that for much of the time both feet are off the ground．
Middle-sized and large birds walk at low speed and either run or hop at higher speed．Small birds, such as sparrows and swallows, usually do not walk, because walking may be too slow for them．It seems that the more time a bird spends in trees, the more likely it is to hop．Perhaps there is wide space in a tree between one thin branch (樹枝) and the next, so walking is not a good choice, while on each small branch there is enough room to set both feet down side by side, so hopping seems to make sense．
（1）How is the bird moving when both feet are on the ground for more than half the time?
A.By flying．
B.By running．
C.By walking．
D.By hopping．
（2）Which of the following shows a bird is hopping?
A.
B.
C.
D.
（3）Why do the birds in trees usually move by hopping?
A.Space between the two branches is wide．
B.The birds in trees are small in size．
C.There is little room to set the birds' feet on．
D.Branches are high in the air off the ground．
（4）Which of the following usually moves by hopping?
A.A duck．
B.A chicken．
C.A snake．
D.A sparrow．
（5）What does the underlined word "gaits" mean?
A.Directions of flying．
B.Speeds of moving．
C.Ways of moving．
D.Times of staying in trees．

（5）C
【解析】這篇文章主要就是講鳥移動的三種步法:慢步走,跑,和雙足跳躍(前進(jìn))。
（1）細(xì)節(jié)理解題。根據(jù)短文第三段中句子In walking, the left and the right feet move in turn (輪流) ．Each foot is on the ground for more than half the time, so there are more times when both feet are on the ground．In running, each foot is on the ground for less than half the time可知在走路的時候是左右腳交替輪流，每只腳在地上的時間都超過(走路)一半的時間,所以有兩只腳一起落地的時間。當(dāng)兩只腳在地上超過一半時，鳥是慢步走的，所以答案是C。
（2）細(xì)節(jié)理解題。根據(jù)第三段最后兩句In hopping, the feet move almost at the same time．This means that for much of the time both feet are off the ground．可知鳥在跳躍中，雙腳幾乎同時移動。所以答案是B。
（3）細(xì)節(jié)理解題。根據(jù)第四段中的句子Perhaps there is wide space in a tree between one thin branch (樹枝) and the next, so walking is not a good choice, while on each small branch there is enough room to set both feet down side by side, so hopping seems to make sense．可知先擇跳躍的方式移動是因?yàn)闃渲﹂g的空隙比較寬。所以答案是A。
（4）推理判斷題。hopping 的意思是雙腳跳，所以根據(jù)四個選項(xiàng)我們可以看出只有第四項(xiàng)麻雀才會雙腳跳。所以答案是D。
（5）詞義猜測題。通讀全文我們可以看出這篇文章主要就是講鳥移動的三種步法。所以答案是C。
