Many animals recognize their food because they see it. So do         . When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other          when you choose your food. You may          it because it smells good or because it          good. You may dislike some types of food because they do not look, smell or taste very nice.

Different          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          types of food, some animals spend their lives eating only one type. The giant panda eats only one         type of bamboo. Other animals eat only one type of food even when given the       . A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other         in the garden. However, most animals have a more          diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The          of these animals will be different depending on the season.

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

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.

Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.

The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr. Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents.  " Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends," he says.

If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use.  Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.

1. From the first two paragraphs, we can know________.

2.Cell phone addiction has caused the following effects EXCEPT________  .

3. The underlined word "curb" in Paragraph 2 means “________. ”

4.The example of a woman talking on the phone in the car supports the idea that________  .

5.Which of the following is the best title for the passage?

It has been argued that an infant under three who is cared for outside the home may suffer because of the separation from his parents．The British psychoanalyst John Bowlby believes that separation from the parents during the sensitive "attachment" period from birth to three may scar （留下疤痕） a child's personality and incline to emotional problems in later life．Some people have drawn the conclusion from Bowlby's work that children should not be sent to day care before the age of three, and many people do believe this．But there are also arguments against such a strong conclusion．

Firstly, anthropologists （人类学家） point out that the hidden love between children and parents found in modem societies does not usually exist in traditional societies．For example, we saw earlier that among the Ngonis the father and mother of a child did not raise their infant alone．But traditional societies are so different from modern societies that comparisons based on just one factor are hard to understand．

Secondly, common sense tells us that day care would not be so widespread today if parents and caretakers found that children had problems with it．But Bowlby's analysis raises the possibility that early day care has delayed effects．The possibility that such care might lead to more mental illness or crime 15 or 20 years later can only be noticed by the use of statistics．Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial．

Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have reported that day care had a neutral of slightly positive effect on children's development．But tests that have had to be used to measure this development are not widely enough accepted to settle the issue．
