Snow falls in the Earth’s extreme North and South throughout the year. However， the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道)，but only on the highest mountains.
Snow contains much less water than rain, but much of the water the world uses comes from snow. Melting snow provides water for rivers, electric power stations and agricultural crops. In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.
Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. Snow also influences the movement of sound waves. The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow’s surface will help to send back sound waves.
Snow may be beautiful, but it can be deadly. It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. Others die from heart attacks caused by too much physical activity out in the cold.
People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. These include food，emergency medical supplies，and extra clothing to stay warm and dry.. Mountain snowfall _____.

NEW YORK (AP) — The investigation into the disappearance of 6-year-old Etan Patz has gone through decades and countries, from basements to rooftops and seemingly everywhere in between.
No one has ever been charged criminally — and the little boy with sandy brown hair and a toothy grin was declared dead in 2001.
This week, the six-year-old boy who went missing from the Soho area of New York City in 1979 is back in the news. Police and the FBI are investigating a possible lead into the 33-year-old case of Etan Patz, the first missing child to appear on the side of a milk box.
The child disappeared on the way to school on the morning of May 25, 1979. It was the first time he was allowed to walk the two blocks to the bus stop alone.
A tip seemed to have led officials to the basement of a building on the corner of Prince and Wooster streets, about a block and a half from where Etan had lived with his family.
The name Etan Patz has become a hot topic on Twitter as people weigh in on the case. Shirley Brady noted: “As mom to a 6 years old in Soho, it’s still held out by locals as cautionary tale (警示故事).” Another wrote, “Boy who disappeared on his way to school in 1979 has been REOPENED! Crazy.” One wondered, “Why is FBI and NYPD searching for a kid that disappeared in 1979?”
Good question. This is a case that Stuart Gra Bois, as an assistant U.S. lawyer under Rudolph Giuliani, followed for years. It became the most famous missing-person case in New York City, turned a nationwide spotlight on missing children, and created headlines around the globe. No one was ever stated guilty of the crime.
The case led to the creation of National Missing Children’s Day, marked on May 25, the day the blond-haired, blue-eyed child went missing.
The case has even pointed to a suspect, charged with child molester (猥亵者) Julio Antonio Ramos, who is currently in prison. Patz’s babysitter had been dating the man, and Ramos did know the kid, but has denied taking him away.
New evidence in the case suggests another suspect who lived in the apartment at the time: a local handyman named Othniel Miller, who gave Etan $1 for helping him the night before the disappearance.
The man’s name had come up in an earlier investigation, but he was a friend of the Patz family, and the NYPD did not follow the lead.
Investigators plan to be at the site, 127 B Prince St.,which is now a Lucky Brand jeans store, for the next two to three days to search for human remains. The Associated Press reports that the excavation (挖掘) has been the result of a recently ordered review of the case by Manhattan’s police.We can learn from the first three paragraphs that ________.
| A．The 6-year-old missing boy was found by the side of a milk box |
| B．Police and the FBI have not been following the case of Etan Patz for 33 years |
| C．The investigation into the disappearance of boy has worked fruitlessly for decades |
| D．Etan Patz went missing from the Soho area of New York city in 1979 and died in 2001 |
What does the underlined phrase “weigh in on the case” mean?
| A．ignore the case | B．feel stressed on the case |
| C．reopen the case | D．begin to discuss the case |
What was a possible cause of reopening the case of Etan Patz?
| A．Local lawyers strongly demanded the reopening of the case. |
| B．The Associated Press reported the result of the review of the case. |
| C．New evidence appeared which led officials to the basement of a building. |
| D．Local people realized the importance of the case without criminal being charged. |
Which of the following statements is true in the text?
| A．The National Missing Children’s Day was created on May 25, 1979. |
| B．The search for human remains will be carried out at 127 B Prince Street. |
| C．The NYPD didn’t follow the lead of Julio Antonio for he had been dating Patz’ babysitter. |
| D．Othniel Miller, a local handyman assisted Etan and gave him $1 before the disappearance. |
We can learn from the passage that ________.
| A．People air the same view about the case on the Internet |
| B．People reject the reopening of the case of the missing boy |
| C．The missing-person case still has a long-lasting influence on people |
| D．Twitter is the only place for people to discuss about missing-person cases |

The second theory to become popular was Carl Jung’s compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer. _____ Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.
Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans. ______ Until they reach age five, they can not express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ.

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations.
Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects(前景) of a commercial return, and Lee’s is one of them.
The impact of a salary cut is probably less serious for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual(智力的) opportunities.
Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary(包括各种学科的) team, manage budgets and negotiate(谈判) contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”By “a one-way street” in the first paragraph, the author means ________.
| A．university researchers know little about the commercial world |
| B．there is little exchange between industry and academia |
| C．few industrial scientists would quit to work in a university |
| D．few university professors are willing to do industrial research |
The word “deterrent” most probably refers to something that _____.
| A．keeps someone from taking action |
| B．helps to move the traffic |
| C．attracts people’s attention |
| D．brings someone a financial burden |
What was Helen Lee’s major consideration when she changed her job in the middle of her career?
| A．Flexible work hours. |
| B．Her research interests. |
| C．Her preference for the lifestyle on campus. |
| D．Prospects of academic accomplishments. |
Guy Grant chose to work as a researcher at Cambridge in order to ________.
| A．do financially more rewarding work |
| B．raise his status in the academic world |
| C．enrich his experience in medical research |
| D．have better intellectual opportunities |
What contribution can industrial scientists make when they come to teach in a university?
| A．Increase its graduates’ competitiveness in the job market |
| B．Develop its students’ potential in research. |
| C．Help it to obtain financial support from industry. |
| D．Adapt its research to practical applications. |
Drunken driving—sometimes called America's socially accepted form of murder—has become a national epidemic(流行病). Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years.
A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or several glasses of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were serious in most courts, but the drunken slaughter(屠宰) has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21, reversing(使翻转) a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the state recently upped it back to 21.
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop “responsible attitudes” about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests and, in many areas already, to a marked decline in accidents, some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who “obviously drunk” and later drove off the road, killing a nine-year-old boy.
As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition(禁止) of alcohol that began in 1919, what President Hoover called the “noble experiment”. They forgot that legal prohibition didn’t stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.From the first paragraph, we can know that _________.
| A．most Americans like drinking |
| B．heavy drinking is hard to avoid |
| C．many Americans are killed by drunk drivers |
| D．Americans are not shocked by traffic accidents |
In America, public opinion about drunken driving has changed because ________.
| A．judges are no longer serious |
| B．new laws are introduced in some states |
| C．the problem has attracted public attention |
| D．drivers do not appreciate their manly image |
What can be inferred from the fact of the traffic accidents in New Jersey?
| A．The legal drinking age should be raised. |
| B．Young drivers were usually bad. |
| C．Most drivers hoped to raise the legal drinking age. |
| D．Drivers should not be allowed to drink. |
Laws recently introduced in some states have _________.
| A．reduced the number of deaths. |
| B．resulted in fewer serious accidents. |
| C．prevented bars from serving drunken customers. |
| D．specified the amount drivers can drink. |
Which of the following best shows the writer’s opinion of drunken driving?
| A．It may lead to organized crime. |
| B．It is difficult to solve this problem. |
| C．The new laws can stop heavy drinking. |
| D．There should be no bars to serve drink. |
