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(大熊猫)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(多样化饮食). 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.

1.We can infer from the text that humans and animals _________.

   A. depend on one sense in choosing food     B.  are not satisfied with their food

   C. choose food in similar ways             D. eat entirely different food

2.Which of the following eats only one type of food?

   A. The white butterfly.                   B. The small bird.

   C. The bear.                            D. The fox.

3.Certain animals change their choice of food when ___________.

   A. the season changes                    B. the food color changes

   C. they move to different places            D. they are attracted by different smells

4.We can learn from the last paragraph that __________.

   A. food is chosen for a good reason         B. French and British food is good

   C. some people have few choices of food    D. some people care little about healthy diet

 

1.解析 选C。推理题。从文章第一段首句可以推出人和动物选择食物的方式是相同的。而这个观点也正式本文的主旨所在。 2.解析 选A。细节题.从文章第二段“…even though there are plenty of other vegetables in the garden.”可以知道,the white butterfly只吃一种食物,而the bear 和the fox是吃多种食物的。 3.解析 选A。 细节题。从文章第二段最后一句可以得出答案。 4.解析 选D。 推理题。本段介绍了人类饮食的定向性不是因为它们对人体有益,而是因为偏爱的缘故,所以由此可以判断出有些人并不是很在意有益于健康的饮食。

   It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.

   The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries(食品杂货),saving us from having to walk long distances from where we live.

   I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.

   People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity(人性)as a whole. And it has influenced(影响)us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.

1.Why was the bike so important to the couple?

   A. The man’s job was bike racing.           B. It was their only possession.

   C. It was a nice Kona 18 speed.             D. They used it for work and daily life.

2.We can infer from the text that ____________.

   A. the couple worked 60 hours a week.       B. people were busy before Christmas

   C. the stranger brought over the bike         D. life was hard for the young family.

3.How did people get to know the couple’s problem?

   A. From radio broadcasts.                 B. From a newspaper.

   C. From TV news.                       D. From a stranger.

4.What do the couple learn from their experience?

   A. Strangers are usually of little help.        B. One should take care of their bike.

   C. News reports make people famous.       D. An act of kindness can mean a lot.
