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.

Whether you live in Seattle or the Sahara desert, the time has come to invest in a good raincoat or umbrella, a new study suggests.
As global temperatures continue to rise, more “extreme rain” events—intense, cats-and-dogs downpours—can be expected, said the study, published Monday in the journal Nature Climate Change. And that, scientists said, means an increased flood risk, particularly for the world’s driest areas. The study challenges the idea that global warming is causing dry areas to become drier and wet areas wetter.
“In both wet and dry regions, we see these great increases in heavy precipitation（冰雹）,” lead author Markus Donat, a climate scientist at the University of New South Wales, told Nature.
Donat and his team collected data from 1951 to 2010 on extreme precipitation events from 11, 000 weather stations around the world, Nature reported.
In that time, the number of days with “extreme precipitation” increased 1 percent to 2 percent per decade. 
“We found a strong relationship between global warming and an increase in rainfall, particularly in areas outside of the tropics,” Donat said in a statement.
“Importantly, this research suggests we will see these extreme rainfall events increases at regional levels in dry areas, not just as an average across the globe,” Donat added.
Peter Stott, a senior climate scientist at Met Office, told Climate Central that the study’s findings are important, because more violent rainfall and flooding will “challenge our capability to adapt to a rapidly changing climate.”
As Nature reported, the research aligns（结盟）with a 2015 study that found global warming has led to a sharp increase in record-breaking precipitation events. Donat told Nature that his study should come as a warning to world governments.
 33. Which of the following is one of the study’s findings?
A. Global warming is causing dry areas to become drier and wet areas wetter.
   B. Extreme rain events can be expected at regional levels in dry areas.
   C. Extreme rainfall events increase at regional levels in wet areas.
   D. Rainfall increases particularly in the tropics areas.
34. Why does Scott think the findings are important?
   A. The research aligns with a 2015 study.
   B. They are about extreme precipitation events.
   C. They remind us to adjust to rapid climate changes.
   D. The study involves many famous climate scientists.
35. The purpose of the study is to ______.
   A. encourage investors to start business in Seattle or the Sahara desert
   B. persuade people to take a raincoat or an umbrella with them
   C. challenge the previous findings of research on climate
   D. warn world governments to focus on global warming

The Value of Tears
Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. They can leave you embarrassed and without energy. However, crying is a fact of life_，and tears are very useful. Even when you’re not crying, they make a film over the eye’s surface.    36  
When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “ People worry about showing their emotions, afraid that once they lose control they’ll never get it back.”    37     After we cry, the feelings that caused the tears often disappear,
Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling-shock, anger, fear, or sadness is being held back.
    But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry.     38    Patients practice crying just to become used to express emotions. She suggests safe, private places to cry, like under the bedcovers or in the car. Crying is a way of ease tension, but people don’t like it when others cry because it makes them tense.     39    And they’ll do just about anything to make you stop.
In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion. 高考英语模拟试题库  http://www.17xuexiba.com/yy/
