Question

 

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊貓）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多樣化飲食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

【答案】

1.解析 選C。推理題。從文章第一段首句可以推出人和動物選擇食物的方式是相同的。而這個觀點也正式本文的主旨所在。

2.解析 選A。細節(jié)題.從文章第二段“…even though there are plenty of other vegetables in the garden.”可以知道，the white butterfly只吃一種食物，而the bear 和the fox是吃多種食物的。

3.解析 選A。 細節(jié)題。從文章第二段最后一句可以得出答案。

4.解析 選D。 推理題。本段介紹了人類飲食的定向性不是因為它們對人體有益，而是因為偏愛的緣故，所以由此可以判斷出有些人并不是很在意有益于健康的飲食。
