Question

【題目】There are many kinds of animals that live in the forest, such as mice, rabbits, squirrels and 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 may be the best title of the passage?

A. Animals in the world B. Food chain C. Plants and man. D. Animals are in danger.

【4】B

【解析】

本文介紹了什么是食物鏈。以及如果食物鏈被破壞了，會產(chǎn)生什么后果。

【1】細節(jié)理解題。根據(jù)句子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，光合作用就是森林中的綠色植物利用太陽的能量為自己制造食物。故選B。

【2】細節(jié)理解題。題干的意思是：食物鏈中的第一個環(huán)節(jié)是什么？由句子A food chain begins with the sun. 食物鏈?zhǔn)菑奶�陽開始的�？芍�，食物鏈中的第一個環(huán)節(jié)是太陽。故選A。

【3】細節(jié)理解題。題干的意思是：動物有時找不到足夠的食物，因為什么。由句子A break（中斷）in any part of this food chain means some animals may not have enough food to eat. 可知，一些動物可能沒有足夠的食物吃是因為食物鏈有一個斷裂。故選D。

【4】推理判斷題。A. Animals in the world世界里的動物；B. Food chain食物鏈；C. Plants and man. 植物和人類；D. Animals are in danger. 動物處于危險之中。根據(jù)句子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. 森林里的動物依靠彼此來獲取食物。許多小的森林動物，比如老鼠，吃綠色植物作為食物，然后較大的動物吃它們。這就是所謂的食物鏈�？芍�，本文的主題是關(guān)于食物鏈的，故選B。

細節(jié)理解題的解題技巧：

一般針對某個特定的細節(jié)而提供，難度較小，屬表層信息理解，考生通讀短文后可直接找出答案依據(jù)。

解題技巧：通讀短文，領(lǐng)會文章大意，理解文章結(jié)構(gòu)層次及細節(jié)，特別注意：

1. 五個W（who, which, when, where, what）和一個H（how）；

2. 數(shù)字、日期、時間等；

3. 注意加強語氣的詞。然后運用排除法排除不符合原文細節(jié)的選項，剩下的就是要選擇的最佳答案。
