Surveillance (监视) is a fact of life. Your boss is monitoring your performance at work. Supermarkets are collecting data on your grocery shopping. 1.
In a few months, European Union law-makers are due to approve proposals that will make driver assistance systems mandatory (强制的) in cars within three years. All new models of car will come with black boxes (event data recorders), intelligent speed assistance, lane-keeping assistance and more besides.
A large number of technologies will soon be monitoring a driver’s every move. Are we prepared for devices that watch how we drive and try to help us do it better?
2. In a report published in April 2018, it found that the suite of changes could save at least 7,300 lives by 2030, and reduce the number of serious injuries from car crashes by 38,900. “We can have the same kind of impact as when safety belts were first introduced,” says Oliver Carsten, who studies transport safety at the University of Leeds, UK.
3. The black box is the most controversial (有争议的) tech because of fears that the tech encourages surveillance. It would be easy to worry about being watched in your car. But the EU rules say the system is only checked in the event of an accident to help with insurance claims and police investigation. The point is to provide for a fair allocation (分配) of responsibility when a crash occurs. Some people choose to have a black box because it can reduce their individual insurance premium (保险费). 4. What’s more, the data collected in human-driven cars will help train automated driving systems to the point that they could be ready for large-scale deployment in the future.
5. Drivers should think of it as an extra layer of protection, rather than the vehicle trying to take over driving from you.
A. Now there is a new field: the automobile.
B. There is concern about these technologies, however.
C. The tech is reducing costs because it’s reducing the number of crashes.
D. Safety isn't much discussed, principally because cars are already very safe.
E. While the EU is taking the boldest steps, these technologies aren't far behind in other parts of the world.
F. As a result, what may at first glance seem like a surveillance technology is actually a benefit for society.
G. The European Commission says that introducing these advanced driver assistance systems will make driving safer.

For most of us, work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, traveling to and from work. What we do there largely determines our standard of living and our status to a considerable extent. It is sometimes said that because leisure has become more important, the injustices of work can be pushed into a corner, and that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustrations and humiliations by concentrating their hopes on the other parts of their lives. For the foreseeable future, however, the material and psychological rewards which work can provide will continue to play a vital part in determining the satisfaction that life can offer.
Yet only a small minority can control the pace at which they work or the conditions where their work is done; only for a small minority does work offer scope for creativity, imagination or initiative.
Inequality at work is still one of the most glaring (明显的) forms of inequality in our society. We cannot hope to solve the more obvious problems of industrial life, many of which arise from the frustrations created by inequality at work, unless we handle it determinedly.
The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are constantly learning. They are able to exercise responsibility. They have a considerable degree of control over their own and others’ working lives. Most important of all, they have opportunities to initiate. By contrast, for most manual workers, work is a boring, dull, even painful experience. They spend all their working lives in intolerable conditions. The majority have little control over their work. It provides them with no opportunity for personal development. Many jobs are so routine that workers feel themselves to be mere cogs (齿轮) in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated (疏远) from their work and their firm.
1.In the writer’s opinion, people judge others mainly by ________.
A.the type of work they do B.the place where they work
C.the time they spend at work D.the amount of money they earn
2.According to the writer, to solve problems in an industrial society, we ________.
A.should create more working opportunities for the poor
B.have to get rid of the unequal aspects in work
C.had better cancel all managing positions in a company
D.should encourage the manual workers to promote efficiency
3.What advantage does the writer say managers have over workers?
A.They won’t be out of work.
B.They get time off to learn constantly.
C.They can work at what interests them.
D.They have complete control over themselves.

Fear is a fact of life everyone faces from time to time. In most cases fear is a healthy reaction to a dangerous situation. But sometimes fear can be so extreme that it interferes with normal living. That is what happened to me driving cross-country last summer.
I’d agreed to help my brother, Mac, move from the East Coast to California. He would drive a rental truck loaded with his belongings and I would follow him in his car, then fly back. We figured it would be a simple trip, with four or five motel (motorists’ hotel) stops along the way.
Living and working in coastal Georgia for most of my life, I did not have a great deal of long-distance driving experience. Looking back on it today, I can see that I’d always felt a sudden, sharp pain of fear when driving over small bridges and along hilly highways. And as I was getting ready for the trip I had an unclear concern about the steep mountain roads that lay ahead. But I thought I would get used to them.
As we crossed some high bridges near the Blue Ridge Mountains on the first leg of our trip, a kind of breathlessness gripped me, a sinking, rolling feeling in the pit of my stomach. I tended to move slightly away from the edge of the roadway and the drop-off beyond. My knuckles (指关节) whitened from my tense grip on the steering wheel. At the end of each bridge, a great rush of relief would come over me, only to be replaced in short order by fear of the next obstacle.
When we stopped in Nashville the first night, I mentioned my feelings lo Mac, who is the practical sort. “Oh, that’s nothing.” he said cheerfully. “Lots of people hale driving on mountain roads and high bridges. Just turn up the music on your radio and focus on that. Keep your mind occupied.”
1.Which is NOT the author’s attitude towards fear?
A. Fear can sometimes disturb your life.
B. It is natural to feel fear in everyday life.
C. In dangerous situations, fear may do good to your body.
D. Whenever you feel fear, you are likely to make a wrong decision.
2.How did the author and his brother go to California?
A. They rented a truck and drove it in turn.
B. The author and his brother drove different vehicles.
C. The author drove while his brother flew to California.
D. The author drove a rented car while his brother drove the truck.
3.To the author the trip is .
A. frightening B. pleasant
C. exciting D. exhausting
4.Mac asked his brother to turn on the radio and focus on that in order to let him .
A. keep using his brains
B. kill time during the long trip
C. think of other things instead of fear
D. enjoy the beautiful music along the way

For most of us, dieting is an annoying fact life. With so much information available, it can be difficult to tell which weight-loss strategies really work. Let’s start by taking a look at some confusing myths (荒谬)。
1.All calories are created equal.
What you eat, not how much, is the main factor behind weight gain. In fact, the body burns many more calories digesting carbohydrates than it does digesting fat ,For every 100 calories of carbohydrates we consume in excess (超过)of our daily requirement ,only 75 are turned into body fat .But 97 of every 100 excess fat calories are turned into body fat .
2.Desserts and fast foods are forbidden.
Some experts advise against describing foods as “ good ”and “bad ”.Even cakes ,pies ,and ice cream can be worked into a diet, Moderation is the key. Besides ,a plain hamburger on a bun is still a healthful choice ,So is baked chicken or a green salad with low –cal,dressing. But watch out for French fries, and fried chicken of fish .
3.It makes no difference whether you’re top or bottom –heavy.
In fact ,where weight is distributed makes all the difference. Recent studies suggest that people who store fat on the upper body (apple shape )rather than on hips and thighs (大腿)脚(pear shape )may have an increased rick of heart disease.There is probably little you can do to change how your body is genetically programmed to store fat ,But you can lost excess weight overall .
4.Fasting is the fastest diet .
Some studies suggest that suddenly reducing calorie intake puts the body into “starvation mode ”,which causes it to conserve calories and decreases the rate of digestion .The more often you deprive yourself of food ,the better your body may get at storing calories ,So ,in the long run ,repeated fasting may actually weaken your weight –loss efforts.
5.To keep weight off ,simply watch what you eat
According to studies ,exercise combined with dieting ensures weight loss better than dieting alone does. Experts also agree that having regular, moderate exercise is more important than occasional exercises. Researchers encourage patients to take the stairs instead of the elevator and park the car far from where you are going and walking.
6.It’s all your fault that you’re fat
Research at the University of Pennsylvania, School of Medicine indicates that body shape and size are in large part decided by a person’s genes. In short ,some people are naturally more likely to be fat than other.Moreover, someone who was fat in childhood will have more fat cells than a person of average weight. Once made, the cells may enlarge or shrink (缩小),but they never disappear.
Yet genes don’t have to control your shape ,The size of your fat cells depends on you ---- on your eating habits and lifestyle ,Most important ,before getting caught up in dietary myths ,let good sense shape your eating habits ,Your body will thank you for it .
1.Whci of the following statements is true?
A. All calories are created equal .
B. You can decide whether fat will be stored on your upper body or lower body.
C. While you are on a diet never eat desserts and fast food
D. The size of fat cells is decided by our eating habits and lifestyle
2.Which of the following statements is true about fat cells and genes?
A. Everyone has the same amount of fat cells .
B. The size of fat cells is fixed ,They won’t become bigger or smaller
C. Genes have nothing to do with obesity.
D. Where you store your fat is genetically decided
3.The main reason why the author writes this article is to ___________
A. give new ideas B. correct certain misunderstandings
C. encourage the readers to keep fit D. explain the concept of calories ,fat cells ,and genes
4.This article is ____________
A. descriptive B. creative C. persuasive D. educative

The fact that your hair turns grey because of stress is nothing more than an old wives' tale. It's true that stress isn't good for you, but it's not going to turn you into a silver fox just yet. In fact, the answer comes from the cells in your hair. These are what decide the color and, eventually, the fade to grey.
Most of us start to notice our first grey hairs by the time we hit our thirties. A general rule to go by is that by the age of 50,half of the population will have lost the color in 50 percent of their hair.
But why does it happen? Firstly, we need to understand how hair gets its color.
Your hair is made up of cells called melanocytes(黑色素细胞) which produce pigments(色素) as they grow into the hair fiber. There are two different types of melanins: eumelanins and pheomelanins. The former produces black and brown pigments, while the latter produces red and yellow pigments. The exact amount of these pigments decides whether a person has black, brown, blonde or red hair.
As we age, the ability of the melanocytes to produce more pigments weakens. That's because our hair grows in different periods.
The growing period lasts between three and five years, after which our follicles(毛囊) turn off for about three months to rest and get ready to grow more hairs. This goes round and round and, after a time, our bodies aren't as good at producing new hairs.
Scientists are continuing to try and find ways to prevent greying hair. A team of scientists in France is working to try and stop the melanocytes from being damaged at the end of each hair cycle. They are trying to use a special enzyme(酶) to protect the cells from damage. If successful, it could lead the way for new products that keep our hair full of color for years to come.
1.The phrase “an old wives' tale” in Paragraph 1 probably mean________?
A.a wrong belief B.useful talk
C.a scientific rule D.helpful experience
2.What do we know about red hair?
A.It doesn't turn grey as people get older.
B.It contains more pheomelanin’s than eumelanin’s.
C.The amount of pigments in it doesn't change over time.
D.People with red hair have weaker ability to produce pigments.
3.What do the French scientists aim to do?
A.To repair damaged hair follicles.
B.To protect hair cells against damage.
C.To shorten the hair cycle to protect the hair.
D.To study the relationship between health and hair color.
4.What can we infer from the article?
A.Grey hair has nothing to do with stress.
B.Grey hair is a symbol of declining health.
C.It takes three months for new hair to grow.
D.The growth and color change of hair depend on cells.
