I like eating fruit and vegetables what are of great benefit to our healthy. Not only do they prevent us from falling into ill, but they help us lose weight. I used to hate vegetables, but follow the doctor’s advice, I gradually kicked the bad habit. Just as an old saying going, “An apple a day keeps the doctor away”. However, there are still many children dislike fruit and vegetables. On contrary, influenced by this or that kind of advertisement, many were crazy about junk food. Consequently, they become weaker and weaker instead of getting strong. In my opinion, we must take action to change them.

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 intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. Increasing their intake 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 age-related 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(被觉察）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 showed these red and yellow hues were linked with the levels of carotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene(番茄红素)—which gives tomatoes and red peppers their red colour—and beta-carotene 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 rush to the skin surface.

1.What do we know from the research?

B. They can prevent heart disease and cancer.

C. They can keep you in good health.

D. They can prevent age-related diseases.

高三英语单项填空中等难度题查看答案及解析

Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered drivers to resist the temptation to take revenge (报复) on uncivilized behavior. On the other hand, a little politeness goes a long way towards reducing the tensions of driving. A friendly nod or a wave of appreciation in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions. But such appreciation of politeness is too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.

However, misplaced politeness can be dangerous. Typical example are the drivers who brakes violently to allow a car to came out of a side street at some danger to following traffic; or the man who wave a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they like to.

An experienced driver, whose manners are faultless, told me it would help if motorists learnt to move correctly into traffic streams one at a time without causing the total blockages that give rise to bad temper. Unfortunately, modern motorists can’t even learn to drive, let alone master the less obvious points of driving perfectly. Years ago the experts warned us that an explosion in car-ownership would demand a lot more give and take from all road users. It’s high time for all of us to take this message to heart.

1. According to the passage, the role of politeness can _______.

A. help us learn about traffic rules

B. reduce the pleasure of driving

C. make our life happier than others’

D. resist the temptation to take revenge on uncivilized behavior

2.By “good sense” in the first paragraph, the writer means ________.

A. the driver’s ability to understand politeness and react reasonably

B. the driver’s immediate response to terrible road conditions

C. the driver’s skill of controlling his or her car in extreme situations

D. the driver’s ability of driving safely in traffic jams

3.Which of the following is NOT misplaced politeness?

A. The driver lets old ladies cross the road when they want to.

B. The driver responses to an act of politeness in a friendly way.

C. The driver suddenly stops to permit a car to come from a side street.

D. The driver waves a child across a zebra crossing into the path of dangerous

oncoming vehicles.

4.In the writer’s opinion, ___________.

A. strict traffic regulations are badly needed

B. drivers should apply road politeness properly

C. rude drivers should be punished

D. drivers should avoid traffic jams
