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 (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.What do we know from the research?

You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their fists. But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes(撞击） through a window and falls thirty feet to the ground below. He is dead！Of course he isn't really dead. With any luck he isn't even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains, who crash cars and run out of them even when they catch fire, are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks. There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress（床垫）. Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar! But although their work depends on trick of this sort, it also requires a high degree of skill and training. Often a stuntman’s success depends on careful timing. For example, when he is "blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment.
Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff（悬崖）a thousand feet high. His parachute（降落伞）failed to open, and he was killed. In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous action. For nowadays there are stuntgirls too. Stuntmen are those who ______.
| A．often dress up as actors |
| B．prefer to lead dangerous lives |
| C．often perform seemingly dangerous actions |
| D．often fight each other for their lives |
Stuntmen earn their living by ______.
| A．playing their dirty tricks | B．selling their special skills |
| C．jumping out of high windows | D．jumping from fast moving trains |
When a stuntman falls from a high building, ______.
| A．he needs little protection | B．he will be covered with a mattress |
| C．his life is endangered | D．his safety is generally all right |
Which of the following is the main factor of a successful performance?
| A．Strength. | B．Exactness. | C．Speed. | D．Carefulness |
What can be inferred from the author’s example of the Norwegian stuntman?
| A．Sometimes an accident can occur to a stuntman. |
| B．The percentage of serious accidents is high. |
| C．Parachutes must be of good quality. |
| D．The cliff is too high. |
This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, ect. You know this because you’ve heard all the statistics on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statement is true, yet this chemical is necessary to all life on earth. The students made a mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave our information that is different from his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people die each year when skiing, while 897 die from lightening strikes, but which is really more dangerous? If you think more about it, you will realize far fewer people go skiing each year than the number of people in danger of a lightning strike. When you think about it again, skiing is more dangerous than you might at first think when looking at the statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. To be warned is just to be prepared.What’s the author’s attitude towards the growing trend of reporting only part of the
information?
Disapproving B. Positive C. Indifferent D. DangerousIn the first paragraph, what does the writer suggest?
| A．We are now living in a dangerous world. |
| B．We get a lot of false statistics from the media. |
| C．There are around us more and more murders diseases, ect. |
| D．Statistics alone without full background don’t give us an accurate picture of things. |
What’s the purpose of the writer’s using the two examples in the second paragraph?
| A．To argue that high school students are easily persuaded. |
| B．To prove what is necessary to us might be dangerous. |
| C．To show the danger of reporting only part of the information. |
| D．To warn us of the harmful substance around us. |
Relative information is often left out because ___________________.
| A．it is not important |
| B．the author is trying to show what he or she says is true |
| C．readers will consider other important information |
| D．readers are able to form an opinion with half-truths |
What can we learn from the passage?
| A．Some measures must be taken to protect our dangerous world. |
| B．The growing trend of reporting only half-truths is getting out of control. |
| C．Teenagers ought to improve their ability of telling right from wrong. |
| D．We should learn to think critically and look at problems from all sides. |
Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil（零）, many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne（升空的）.
● Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
● Choose larger aircraft.
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply（遵守）with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
● Pay attention to the pre-flight safety briefing
The information may seem repetitious（重复的）, but it's worth listening to the flight attendants. And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
● Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence（气流）.
● Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
● Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them. What is the overall reason for these air safety tips?
| A．What to do in the event of a crash. |
| B．How to avoid turbulence. |
| C．How to improve safety while you are flying. |
| D．How to avoid injury. |
The underlined word “those” in the second tip refers to ____
| A．smaller planes | B．passengers |
| C．larger aircraft | D．safety records |
The underlined phrase “The general rule” in the fifth tip refers to ____.
| A．anything the flight staff tell you to do | B．general safety advice |
| C．walking around the plane | D．pouring hot drinks |
Which of the following is NOT true?
| A．Larger planes have more safety checks and are safer in an accident. |
| B．Take-offs are safer on non-stop flights than landings. |
| C．Every aircraft is different, so the safety procedures may be different. |
| D．Seat belts should be worn to protect against turbulence. |
The best title of the passage should be____.
| A．The Safest Way to Travel | B．Air Safety Tips |
| C．Non-stop Routes | D．How to Fly a Plane |
I needed to get some money so, after Christmas, I took a job in the clothes department at Graham's for the first fortnight of the January sale．I can't say that I enjoyed it, but it was an experience I'll never forget．
I could never understand why there were so many things in the sales, where did they all come from? Now I know the secret! Firstly, there is the special winter stock （货物） and the stock that people buy all the year round; some of these things are slightly reduced．Secondly, there are the summer clothes they couldn't sell last year; these are heavily reduced to clear them．Thirdly, there are cheap clothes bought in specially for the sales; these are put out at high prices ten days before the sale begins and then are reduced by 60% in the sale．Clever! Lastly, they buy in “seconds”（clothes not in perfect condition） for the sale and they are sold very cheaply．
When I arrived half an hour before opening on the first day of the sale, there was already a queue around three sides of the building．This made me very nervous．
When the big moment arrived to open the doors, the security guards looking less confident than usual, came up to them, keys in hand．The moment they had unlocked the doors, they hid behind the doors for protection as the noisy crowd charged in．I couldn't believe my eyes; this wasn't shopping, it was a battlefield! One poor lady couldn't keep her feet and was knocked over by people pushing from behind．
Clothes were flying in all directions as people searched for the sizes, colours and styles they wanted．Quarrels broke out．Mothers were using their small children to crawl through people's legs and get hold of things they couldn't get near themselves．

The whole day continued like that, but I kept my temper81 was taking money hand over fist and began to realize why twice a year, Graham's were happy to turn their expensive store into a battlefield like this．
In the sale fever; people were spending money like water without thinking whether they needed what they were buying．As long as it was a bargain it was OK．You won't believe this．But as soon as I got home I crashed out for four hours．Then I had dinner and went back to bed, fearing the sound of the alarm which would tell me to get ready for the second day of the sale.

This brief book is aimed at high school students, but speaks to anyone learning at any stage of life.
Its formal, serious style closely matches its content, a school-masterly book on schooling. The author, W. H. Armstrong, starts with the basics: reading and writing. In his opinion, reading doesn’t just mean recognizing each word on the page; it means taking in the information, digesting it and incorporating it into oneself just as one digests a sandwich and makes it a part of himself. The goal is to bring the information back to life, not just to treat it as dead facts on paper from dead trees. Reading and writing cannot be completely separated from each other; in fact, the aim of reading is to express the information you have got from the text. I’ve seen it again and again: someone who can’t express an idea after reading a text is just as ineffective as someone who hasn’t read it at all.
Only a third of the book remains after that discussion, which Armstrong devotes to specific tips for studying languages, math, science and history. He generally handles these topics thoroughly and equally, except for some weakness in the science and math sections and a bit too much passion regarding history. Well, he was a history teacher —if conveyed only a tenth of his passion to his students, that was a hundred times more than my history teachers ever got across.
To my disappointment, in this part of the book he ignores the arts．As a matter of fact, they demand all the concentration, and study that math arid science do, though the study differs slightly in kind．Although it's commonly believed that the arts can only be naturally acquired, actually, learning the arts is no more natural than learning French or mathematics．
My other comment is that tke text aged．The first edition apparently dates to the 1960s—none of the references （参考文献） seem newer than the late 1950s．As a result, the discussion misses the entire computer age．
These are small points, though, and don't affect the main discussion．I recommend it to any student and any teacher, including the self-taught student．According to Armstrong, the goal of reading is to ____.
| A．gain knowledge and expand one's view |
| B．understand the meaning between the lines |
| C．express ideas based on what one has read |
| D．get information and keep it alive in memory |
The author of the passage insists that learning the arts___.
| A．requires great efforts | B．demands real passion |
| C．is less natural than learning maths | D．is as natural as learning a language |
What is a shortcoming of Armstrong's work．according to- the author?
| A．Some ideas are slightly contradictory． |
| B．There is too much discussion on studying science． |
| C．The style is too serious． |
| D．It lacks new information． |
This passage can be classified as ___．
| A．an advertisement | B．a book review |
| C．a feature story | D．a news report |
