While drunken driving may be on the decline, traffic safety experts remain puzzled over how to deal with another alcohol related danger: drunken pedestrians(行人).
Pedestrians struck and killed by cars often are extremely drunk. In fact, they are intoxicated(喝醉的) more frequently and with higher blood alcohol levels than drunken drivers who are killed in accidents, various studies have shown. Forty percent of adult pedestrians involved in fatal crashes have a blood alcohol level of at least 0.10 which by law in most states signifies intoxication compared to only 25 percent of drivers in deadly accidents, according to recent federal data.
Some types of pedestrain accidents have been declining nationally, especially those involving children, but the number of adult pedestrians who are drunk when killed in traffic has remained relatively steady at 2500 a year. The total number of pedestrians killed annually in U.S. traffic accidents is at least 7000, or one of every seven highway accidents resulting in death.
“We’re dealing here, we think, with a very severe drinking problem that leads to a severe highway safety problem,” said Richard Blomberg, president of Dunlap and Associates Inc, in Norwalk, Coon.
Blomberg, whose consulting company found a very high rate of alcohol involvement in a controlled study of pedestrian accidents in New Orleans, was among several researchers who spoke on the topic at the annual meeting of the Research council’s Transportation Research Board(TRB) in Washington in January.
Pedestrian accidents have not received enough attention in the past, according to Kay Colpitts, who chairs the board’s committee on pedestrians. Few methods exist to monitor walking habits, she said, and researchers have been mystified（迷惑不解） about how to prevent disasters.

One would have to be a fool to overlook (忽视)the importance of using positive(积极的) thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little chemicals and good feelings which will reinforce the positive thoughts.
For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate (导致)thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.
It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.We can infer from the passage that .
| A．positive thinking can cure you of your diseases |
| B．positive thinking can easily be generated by anyone |
| C．a decline of hormone may cause you to be depressed |
| D．a specific chemical reaction is the cause of negative thinking |
According to the passage, which of the following is true?
| A．Feeling and thoughts can generate each other. |
| B．It's easier to control thoughts than to control feelings. |
| C．Your success depends wholly on your attitude. |
| D．Keeping smiling will surely make you successful. |
Just like a one-eyed man in the land of the blind, you should.
| A．control your feeling to what is happening to you |
| B．be king in your office |
| C．pay no attention to what is going on around you |
| D．take positive attitude in the office of militant negativism |
The best title to the passage is.
| A．The Bad Effect of Negative Thinking | B．Why Should People Think |
| C．Thinking: The Vital Way | D．Positive Thinking Benefits People |

Few people realize that there is a big difference between formal English and informal English. Formal English is used for most writing, and often in public speaking and formal meetings. It pays close attention to grammar rules, because if we use proper grammar, our meaning is often more precise. Also, on important occasions, we do not want to appear uneducated or to offend (冒犯) others, so we are very careful about how we speak. Informal English is used in speaking or writing to our friends and family. It often does not pay such close attention to grammar rules, because when we speak or write to them, we want our words to flow quickly. Also, with our friends and family, we are usually not so worried about appearing uneducated or about offending them by how we write or speak.
A big difference between formal and informal English is the use of contractions. A contraction is where we make a word shorter or where we put two words together and take away some of the letters. For example, instead of saying “do not”, many people say “don’t”. Using contractions in our speech is fine because it sounds natural, especially when we speak to our friends. In formal writing, however, contractions are usually avoided because people might think that you have made a mistake, or that you do not know proper grammar.
In the same way we might make words shorter, in informal English we often make sentences shorter as well. For example, if someone asks you your name, you will likely answer with one word: your first name. However, in formal English we usually use complete sentences. For example, we might write “My name is John”. In most speaking, we may not need to use every word in a sentence because the person we are speaking to will probably still understand us. In most writing, however, every word in a sentence must be written out in order to make sure that we can be understood.When we use formal English, _______.
| A．we will offend others |
| B．we will appear educated on important occasions |
| C．we needn’t pay more attention to grammar rules |
| D．we can express ourselves more directly and more quickly |
What’s the meaning of the underlined word “precise”?
| A．clear | B．direct | C．puzzling | D．simple |
Contractions are best used when we are _______.
| A．speaking at a formal meeting | B．speaking in public |
| C．speaking to our friends | D．writing an application (申请) letter |
In speaking, we do not always use complete sentences because ______.
| A．we do not care about grammar | B．we do not want to sound stupid |
| C．we can still be understood | D．we don’t want to waste time |
Why do some people flush when they drink alcohol? This effect is a common reaction to alcohol among East Asians. It affects about 36 percent of Japanese, Chinese and Koreans.
For many, even a small amount of alcohol can cause unpleasant effects. Most commonly, their face, neck and sometimes their whole body turn red. People might also feel uncomfortable and sick to their stomach. They might experience a burning sensation, increased heart rate, shortness of breath and headaches.
The cause is a genetic difference that they are born with called an ALDH2 deficiency (缺乏). It prevents their bodies from treating alcohol the way other people do. But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus (食道) from drinking alcohol.
The more alcohol people with this deficiency drink, the greater their risk is. In Japan and South Korea, for example, many people have the deficiency but still drink heavily. Researchers found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.
Esophageal cancer is one of the deadliest cancers. It can be treated when found early, but once it grows the chances of survival drop sharply. The researchers estimate that at least five hundred forty million people have the deficiency, about eight percent of the world’s population.
Philip Brooks is a researcher at the National Institute in the United States. He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer. He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol. Those with a history of it should be advised to limit their alcohol use. They should also be warned that cigarette smoking works with the alcohol in a way that further increases the risk of esophageal cancer.The underlined word “flush” in Paragraph 1 probably means “_________”.
| A．walk unsteadily | B．turn red in the face |
| C．appear unpleasant | D．talk more than usual |

Cell Phones Are the New Cigarettes
When you get in your car, you reach for it．When you’re at work, you take a break to have a moment alone with it．When you get into a lift, you play with it．
Cigarettes? Cup of coffee? No, it’s the third most addictive thing in modern life, the cell phone．And experts say it is becoming more difficult for many people to curbtheir longing to hug it more tightly than most of their personal relationships．
With its shiny surface, its smooth and satisfying touch, its air of complexity, the cell phone connects us to the world even as it disconnects us from people three feet away．In just the past couple of years, the cell phone has challenged individuals, employers, phone makers and counselors（顾问）in ways its inventors in the late 1940s never imagined．
The costs are becoming even more evident, and I don’t mean just the monthly bill．Dr．Chris Knippers, a counselor at the Betty Ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality．
Sounds extreme, but we’ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him．
Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?
Jim Williams, an industrial sociologist based in Massachusetts, notes that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation．He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with．Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don’t have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says．
If the cell phone has truly had these effects, it’s because it has become very widespread．Consider that in 1987, there were only 1 million cell phones in use．Today, something like 300 million Americans carry them．They far outnumber wired phones in the United States．Which of the following best explains the title of the passage?
| A．Cell phone users smoke less than they used to． |
| B．Cell phones have become as addictive as cigarettes． |
| C．More people use cell phones than smoke cigarettes． |
| D．Using cell phone is just as cool as smoking cigarettes． |
The underlined word “curb” in Paragraph 2 means ____．
| A．rescue | B．ignore | C．develop | D．control |
The example of a woman talking on the phone in the car supports the idea that ．
| A．women use cell phones more often than men |
| B．talking on the phone while driving is dangerous |
| C．cell phones do not necessarily bring people together |
| D．cell phones make one-on-one personal contact easy |
