【正确答案】 B

【答案解析】[听力原文]
Many animals recognise 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 eats only one particular type of bamboo. Other animals eat only one type of food even when given other choice. A kind of white butterfly 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. 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.

What can we infer about humans and animals from the passage?

[解析] 选项中的eat...different food, in similar ways和choosing food表明，本题可能与食物选择的异同有关。短文中提到熊和人一样也吃水果和鱼，故排除A；人类可以用眼睛、鼻子等来选择食物，并不是只依靠一种感官来选择食物，而有的动物就只用一种感官来选择食物，故排除D。短文之所以把动物和人类进行比较，是为了说明他们选择食物的方式很相似，故答案为B。

When do certain animals change their choice of food?

[解析] 选项中的When the season/food colour changes和When...move to different places表明，本题可能考查选择食物的条件。短文中提到The diet of these animals will be different depending on the season (这些动物选择的食物随着季节的变化而变化)，其中these animals指的是前面提到的熊和狐狸之类的杂食动物，故答案为A。A选项中when the season changes是对depending on the season的同义转述。

【正确答案】 D

What can we learn from the passage?

[解析] 由短文中提到的We often eat food because we like it and not because it is good for us可知，人们选择食物的标准是根据喜好而非食物本身对健康的影响，故答案为D。because后面的内容为常考点，是听音重点。
