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 healthier and an extra 3.3 portion could enhance their attractiveness, when their photographs were rated by others.

Fruit and vegetables are rich in carotenoids (類(lèi)胡蘿卜素)，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(被覺(jué)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(番茄紅素)-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?

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

B. The researchers took the pictures of the 35 people in the research at different stages.

C. Increasing your intake of greens by 2.9 portions a day can greatly improve 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 age-related 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 the 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 beta-carotene and polyphenols affect skin colour by causing blood rush to the skin surface.

5.Which can be the best title of the passage?

A. Eating fruit and vegetables does good .

B. Fruit and vegetables are rich in carotenoids.

C. How to become attractive.

D. Eating fruit and vegetables makes you look good

American researchers have discovered that human brains and sleep patterns are confused by devices(裝置) that give out bright lights. Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk of insomnia.

Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it.

A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone (荷爾蒙) called melatonin that makes us sleepy.

Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive (干擾的)during the night when the brain thinks it should be dark.

Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp(燈) light doesn't affect the brain as it does not look straight into a person's eyes.

“Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating (刺激) to the brain to make it more awake and delay your ability to sleep，” Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN.

“And I think more importantly, it could also be enough to affect your circadian (晝夜節(jié)律的) rhythm. This is the clock in your brain that determines when you sleep and when you wake up. ”

Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, “I wish people would just take a boring book — an oldfashioned book — and read by a lamp.”

1.The underlined word “insomnia” in the first paragraph probably means “________”．

A．being unable to eat properly

B．brain injury

C．being unable to fall sleep

D．lack of energy

2.Melatonin is the hormone that ________.

A．makes us sleepy

B．helps us relaxed

C．prevents us from waking up

D．makes us excited

3.The bedside lamp light doesn't affect the brain because ________.

A．it doesn't give out blue light

B．it's not as bright as your laptop

C．it doesn't enter your eyes directly

D．it is adjustable

4.We can conclude from the passage that ________.

A．one who uses his laptop often before bedtime can have his body clock disturbed

B．using a laptop before bedtime is more harmful than using an iPad

C．we'd better not do anything before going to bed

D．the best time to go to bed is before 9 pm
