The professor talked to American and Brazilian students about lateness in both an informal and a formal situation: at a lunch with a friend and in a university class. He found that if they had a lunch appointment with a friend, the average American student defined lateness as 19 minutes after the agreed time. However, the average Brazilian student felt the friend was late after 33 minutes.
In an American university, classes not only begin at the scheduled time in the United States, but also end at the scheduled time. In the Brazilian class, only a few students left the class at 12: 00; many remained past 12: 30 to discuss the class and ask more questions. While arriving late may not be very important in Brazil, neither is staying late.
The word "punctual' most probably means______.
A．leaving soon after class
B．coming early
C．arriving a few minutes late
D．being on time
Rather than taking the final then, what they did was to find Professor Aldric after the final and explain to him why they missed the final. They told him that they went up to UVA for the weekend, and had planned to come back in time to study，but they had a flat tire (爆胎）on the way back and didn’t have a spare and couldn’t get help for a long time and so were late getting back to campus.
Aldric thought this over and then agreed that they could make up the final on the following day. The two guys were overjoyed and relieved. So, they studied that night and went in the next day at the time that Aldric had told them. He placed them in separate rooms and handed each of them a test booklet and told them to begin.
They looked at the first problem, which was something simple about free radical formation and was worth 5 points. “Cool，" they thought, “this is going to be easy. " They did that problem and then turned the page. They were unprepared, however, for what they saw on the next page. It said: (95 points) Which tire was flat？

A youngster"s social development has a profound effect on his academic progress．Kids who have trouble getting along with their classmates can end up behind academically as well and have a higher chance of dropping out（退学）．In the early grades especially，experts say，youngsters should be encouraged to work in groups rather than individually so that teachers can spot children who may be having problems making friends．“When children work on a pro-ject，”says Lillian Kate，an educational professor at the University of Illinois，“they learn to work together，to disagree，to think to take turns and lighten tensions．These skims can’t be learned through lecture．We all know people who have wonderful technical skills but don’t have any social skills．Relationships should be the first R．”At a certain age，children are also learning to judge themselves in relation to others．For most children，school marks the first time that their goals are not set by an internal clock but by the outside world．Just as the l-year-old struggling to walk the 6-year-old is struggling to meet adult expectations．“Young kids don’t know how to distinguish early-childhood education for the state of New Jersey，if they try hard to do something and fail，they may conclude that they will never be able to accomplish a particular task．The effects is serious，”says Hills，“a child who has had his confidence really damaged needs a rescue operation．”

Generations of Americans have been brought up to believe that a good breakfast is one life’s essentials. Eating
breakfast at the start of the day, we have all been told, and told again, is as necessary as putting gasoline in the
family car before starting a trip.
But for many people the thought of food first thing in the morning is by no means a pleasure. So despite all the
efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures are available, the
number of people who didn’t have breakfast, increased by 33 percent.
For those who feel pain of guilt about not eating breakfast, however, there is some good news. Several studies
in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast.
“Going without breakfast does not affect performance,” said Arrold E. Bender, former professor of the nutrition
at Queen Elizabeth College in London, “nor does giving people breakfast improve performance.”
Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most
of the recent work involves children, not adults, “The literature”, says one researcher, Dr. Erresto at the University
of Texas, “is poor”.
The latest year for which figures could be obtained is _______.
A. the year the author wrote the article
B. 1977
C. any year between 1997 and 1983
D. 1983
In many modem countries it has for some time been fashionable to think that, by free education for all-whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider" low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, We can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.
Education is ______.
A．a means
B．a purpose
C．fashionable
D．the first system
“The find is of 16 scientific meaning,” said Konrad Spindler, professor of Early and Primeval History at the University of Innsbruck, who is investigating the 17 .Skeletal remains of buried corpses have been excavated before in Bronze Age graves.But “the iceman,” as Austrian newspapers dubbed him, was going about the normal course of life when he died 18 the ages of 20 and 40, which means he should yield a treasure-trove of information about conditions 4,000 years ago.Scientists plan to 19 the contents of his stomach and intestine for clues to the Bronze Age diet, illnesses, and parasites.They also hoped to 20 the glacier site further for companions.

In 2015, the US Forest Service for the first time spent more than half of its $5.5 billion annualbudget fighting fires－nearly double the percentage it spent on such efforts 20 years ago. In effect,fewer federal funds today are going towards the agency&39;s other work－such as forest conservation,watershed and cultural resources management, and infrastructure upkeep －that affect the lives of all Americans. Another nationwide concern is whether public funds from other agencies are going into constructionin fire-prone districts. As Moritz puts it, how often are federal dollars building homes that are likelyto be lost to a wildfire？
“It’s already a huge problem from a public expenditure perspective for the whole country, We need to take a magnifying glass to that. Like, “Wait a minute, is this OK ？”“Do we want insteadto redirect those funds to concentrate on lower-hazard parts of the landscape？ ” Such a view would require a corresponding shift in the way US society today views fire, researcherssay.
For one thing, conversations about wildfires need to be more inclusive. Over the past decade, thefocus has been on climate change－how the warming of the Earth from greenhouse gases is leadingto conditions that worsen fires. While climate is a key element, Moritz says, it shouldn’t come at the expense of the rest of theequation.
“The human systems and the landscapes we live on are linked, and the interactions go both ways,"he says. Failing to recognize that, he notes, leads to "an overly simplified view of what the solutionsmight be. Our perception of the problem and of what the solution is becomes very limited. At the same time, people continue to treat fire as an event that needs to be wholly controlled andunleashed only out of necessity, says Professor Balch at the University of Colorado. But macknowledging fire&39;s inevitable presence in human life is an attitude crucial to developing the laws,policies, and practices that make it as safe as possible, she says.
“We’ve disconnected ourselves from living with fire, ” Balch says. “It is really important tounderstand and try and tease out what is the human connection with fire today. ”
36.More frequent wildfires have become a national concern because in 2015 they_____.
A.exhausted unprecedented management efforts
B.consumed a record-high percentage of budget
C.severely damaged the ecology of western states
D.caused a huge rise of infrastructure expenditure
While admitting that climate is a key element, Moritz notes that _____.A.public debates have not settled yet
B.fire-fighting conditions are improving
C.other factors should not be overlooked
D.a shift in the view of fire has taken place
The overly simplified view Moritz mentions is a result of failing to _____.A.discover the fundamental makeup of nature
B.explore the mechanism of the human systems
C.maximize the role of landscape in human life
D.understand the interrelations of man and nature
Moritz calls for the use of "a magnifying glass" to _____.A.raise more funds for fire-prone areas
B.avoid the redirection of federal money
C.find wildfire-free parts of the landscape
D.guarantee safer spending of public funds
Professor Balch points out that fire is something man should _____.A.do away with
B.come to terms with
C.pay a price for
D.keep away from

The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations. But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents' son. In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two rapes and murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples(样本). The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person's privacy. That includes a person's medical history, racial origin or psychological profile. "There is the long-term risk that people can get into these samples and start getting additional information about a person's paternity or risk of disease," Jeffrey said.
DNA testing is not an unfailing proof of identity. Till, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey's estimates(估计) the probability of two individuals' DNA profiles matching in the most commonly used tests at between one in a billion or one in a trillion.
The passage is mainly about ______.
A．the discovery of fingerprinting by Jeffery
B．the practice of fingerprinting in court
C．the fingerprinting in the present situation
D．the merits and demerits of fingerprinting
