Question

【題目】根據(jù)短文內(nèi)容選擇正確答案。
C
There are many kinds of animals that live in the forest, such as mice, rabbits, squirrels, bears.
Animals in the forest depend on（依靠）one another for food. Many small forest animals, such as mice, eat green plants for food, and then larger animals eat them. This is called food chain. A food chain begins with the sun. The green plants in the forest use the sun's energy to make food for themselves. It's called photosynthesis(光合作用). Mice eat flowers and seeds that forest plants produce(生產(chǎn)).The mice get their energy from the plants, and the mice become food for a larger animal, such as the hunting hawk. So the energy from the sun passes from the plants to the mice to the hawk. A break（中斷）in any part of this food chain means some animals may not have enough food to eat.
（1）Photosynthesis takes place when _____________.
A.larger animals eat small animals.
B.green plants use the sun's energy to make food.
C.Forest animals eat the food made by green plants.
D.The food chain is broken.
（2）What's the first link（環(huán)） in a food chain?
A.The sun
B.The earth
C.Green plants
D.Forests animals
（3）Animals sometimes cannot find enough food because _____________.
A.it's cloudy.
B.there is very little food in a forest.
C.Photosynthesis stops.
D.There is a break in the food chain.
（4）What does the food chain show about living things?
A.They depend on each other.
B.Large animals eat small animals.
C.Plants with flowers are the most important.
D.Plants are more than animals.
（5）What may be the best title of the passage?

（3）D
（4）A
（5）B
【解析】短文大意：森林中生活著各種各樣的動物，這些動物互相為食，小動物吃綠色的植物，大一些的動物吃小動物，這就形成了食物鏈。食物鏈?zhǔn)菑奶�陽開始的，綠色的植物需要用太陽來為它們自己獲得食物，這叫作“光合作用”。食物鏈中任何一個環(huán)節(jié)的中斷都會導(dǎo)致一些動物沒有足夠的食物吃。
（1）細(xì)節(jié)理解題。根據(jù)第二段內(nèi)容The green plants in the forest use the sun's energy to make food for themselves. It's called photosynthesis(光合作用). 可知“光合作用”的形成，故選B。
（2）細(xì)節(jié)理解題。根據(jù)文章中的句子A food chain begins with the sun. 可知“食物鏈”的第一個環(huán)節(jié)是太陽。故選A。
（3）細(xì)節(jié)理解題。根據(jù)文章最后一句A break（中斷）in any part of this food chain means some animals may not have enough food to eat.可知有時動物找不到食物吃是因?yàn)槭澄镦溨袛嗔恕９蔬x D。
（4）推理題。根據(jù)第二段內(nèi)容 Animals in the forest depend on（依靠）one another for food. Many small forest animals,……This is called food chain.可以推理“生物之間是互相依賴的”，故選A。
（5）主旨?xì)w納題。通讀全文，可知本文主要講述了食物鏈的形成，故標(biāo)題選B最合適。
