3. Tom is always the first        (come) to school.

2. The meeting        (hold) yesterday was very important.

  I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true,they are practically impossible to prove scientifically. Still,I was struck by a report which concluded that today's children are significantly more anxious than chil?dren in the 1950s. In fact,the analysis showed,normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for men?tal illness 50 years ago.

  Why are America's kids so stressed? The report cites two main causes: increasing physical isolation (隔离) brought on by high divorce rates and less involvement in community,among other things and a growing perception that the world is a more dangerous place.

  Considering that we can't turn the clock back,adults can still do plenty to help the next generation.

  At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.

  To help kids build stronger connections with others,you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships,and they will get more sleep.

  Limit the amount of virtual (虚拟的) violence your children are exposed to. It's not just video games and movies;children see a lot of murder and crime on the local news.

  Keep your expectations for your children reasonable. Many highly suc?cessful people never attended Harvard or Yale.

  Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.

  A You know eating fruit and vegetables does good. But do you know it can also make you look good? People who increased their intake over just six weeks developed a healthy glow and appeared more attractive,researchers found. Scientists at St Andrews University found eating them slightly increased yellow and red pigments in the volunteers' skin. They monitored the food in?take of 35 people and took pictures of their faces,arms and hands using a sen?sitive camera at the start,and after three and six weeks. Increasing their in?take of greens by 2. 9 portions a day was found to make the person look more healthy and an extra 3. 3 portions could enhance their attractiveness,when their photographs were rated by others.

  Fruit and vegetables are rich in carotenoids (类胡萝卜素) ，which are known to protect against cell damage from pollution and UV rays,and can also prevent agerelated diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange,it was not known a small increase was perceptible (可察觉的) to others―and was seen as appealing.

  A camera measured changes to the skin's redness,yellowness and lightness,and found it significantly changed in people who naturally increased their intake. These changes were not evident in three weeks. Using light sensors,the researchers found these red and yellow hues were linked with the levels of ca?rotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene (番红素) 一which gives tomatoes and red peppers their red colour―and betacarotene found in carrots as well as broccoli,squash,and spinach. Skin colour is also affected by chemicals called polyphenols (多元酚) ，found in apples,blueberries and cherries,which cause blood to rush to the skin surface.

1. What do we know from the research?

   A. If you take in a little more fruit and vegetables,you will obviously look more attractive in three weeks.

   B. The researchers took pictures of the 35 people in the research at differ?ent stages.

   C. Increasing your intake of greens by 2. 9 portions a day can greatly im?prove your health.

   D. People who increased their intake of greens by 3. 3 portions a day were found the most attractive after six weeks.

2. Which of the following is NOT the function of carotenoids?

   A. They can protect against cell damage from pollution and UV rays.

   B. They can prevent heart disease and cancer.

   C. They can prevent agerelated diseases.

   D. They can keep you in good health.

3. Which of the statements is NOT true according to the passage?

   A. We've already known eating extreme amounts of carrots can turn skin orange.

   B. We knew in the past that eating a few more carrots could make us look appealing.

   C. The research showed the improvement in skin is linked with the levels of carotenoids in it.

   D. Among hundreds of carotenoids,lycopene is thought to have the most dramatic effect on skin.

4. We can infer from the passage that         .

   A. skin's redness,yellowness and lightness make a person look more healthy and attractive

   B. carotenoids have the same effect as lycopene

   C. it is carotenoids that give tomatoes and red peppers their red colour

   D. both betacarotene and polyphenols affect skin colour by causing blood to rush to the skin surface
