四、阅读理解
In nature, you may see many insects and
animals of different colours. Have you ever wondered why
Locusts are super delicious food for birds,
but it is not always an easy job for birds to catch them. It is neither because
locusts are good jumpers or runners nor because they are smarter than their
enemies. The reason is that the colours of locusts change with the colours of
crops. When crops are young, locusts look green. But when autumn comes, locusts
change to the yellow and brown colour as crops do.
Brown bears, tigers and other animals move
quietly through forests. They can't be seen easily by their enemies. This is
because they have colours similar to the trees. For the same reason, polar
bears that live on a land of snow and ice are white. Butterflies and bees
living among the flowers are colourful like flowers. Soil insects are mostly
dark coloured and they live under the soil in a dark and wet environment.
However, insects with colours different from plants can easily be found and eaten
by others. So in order to survive, they have to hide themselves in the
daytime and appear only at night.
Have you ever noticed some even stranger
acts The ink fish in the sea can send out some very black ink when it faces
danger. As the ink spreads over, its enemies will find themselves suddenly in a
dark world. At the same time the ink fish immediately swims away. That is how
it keeps itself safe though it is not strong at all.
（31）It is not easy for birds to catch locusts because___________.
A．locusts are good runners B．locusts can jump very high
C．locusts are smarter than birds D．locusts can change their colours
（32）According to the passage, most soil insects___________.
A．do not have bright colours
B．change their colours with the soil
C．do not live in a dark or wet environment
D．eat colourful insects like butterflies and bees
（33）What's the meaning of the underlined word "survive" in the passage
A．繁殖 B．产卵 C．觅食 D．生存
（34）The ink fish __________so that its enemies will not see it.
A．changes its colour B．makes the water around it black
C．appears only at night D．hides itself in the sea rocks
（35）What is the main idea of this passage
A．Some insects and animals have different skills.
B．Some insects and animals are cleverer than we think.
C．Some insects and animals use colours to protect themselves.
D．Some insects and animals can get used to the environment easily.
五．阅读下面短文，按照句子结构的语法性和上下文连贯的要求，在空格处填入一个适当的词或使用括号中词语的正确形式填空。
Have you ever heard of friendships among animals At a zoo in Germany, an unusual friendship developed 　 36 　a cat and a bear.
No one is quite sure how the friendship first began. One day, some 　 37 　 (worker) in the zoo noticed a black cat was in the bear's cage, and the two animals were playing together peacefully. They were surprised 　 38 　well the small cat seemed to get along with the large bear. The bear keeper allowed the cat 　 39 　 (stay) with the bear. And later the pair and their unusual friendship 　 40 　 (become) a hot topic at the zoo.
After several years, a new cage 　 41 　 (build) for the bear. However, the cat was still in the same cage, so it walked around 　 42 　 (angry) and cried to be with the bear.
