Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, say, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease.Last week a report in the New England Journal of Medicine added strong new evidence in support of that theory.More important, the work provided the first solid indication of how alcohol works to protect the heart.
In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvad Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex.The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are.The apparent source of the protection: those who drank alcohol had higher blood levels of high density lipoproteins (脂蛋白), the so called good cholesterol (胆固醇), which is known to prevent heart disease.
As evidence has mounted (增长), some doctors have begun recommending a daily drink for patients of heart diseases.But most physicians are not ready to recommend a regular happy hour for everyone.The risks of teetotal ling (绝对戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles---not to mention violent behavior and traffic accident.Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer.Until there is evidence that the benefits of a daily dose(吸收剂量) of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighborhood bar or liquor store.
60.The report mentioned in the first paragraph indicates________.
A.the way in which alcohol can help the heart.
B.that a couple of cocktails daily can help stop heart problems
C.why alcoholic drinks are dangerous to one’s health
D.that reports on the advantages of alcohol were misled
61.Experiments showed that nondrinkers had___________.
A.larger amounts of good cholesterol   B.smaller amounts of good cholesterol
C.higher blood pressure              D.lower blood pressure
62.According to the passage, moderate drinking_______.
A.is recommended by most doctors for heart patients
B.should be allowed on prescription
C.is still not medically advisable
D.is not related to liver problems
63.The main theme of this passage is___________.
A.the change in recent drinking habits
B.the connection between cancer and alcohol
C.whether moderate drinkers outlive nondrinkers
D.whether alcohol may be good for one’s health

Each child has his individual(个人的)pattern of social, as well as physical, development. Some of it depends on his home life and his relationships with the people who love him. Children in large families learn how to get along with others through normal brother- sister play and tussles (打斗). An only child, on the other hand , may have to learn his lessons in social living through hard experiences on the playground or in the classroom. Twins who always have one another to lean on may be slow in responding to others because they do not need anyone else.
  A child who is constantly scolded and made to feel he does everything wrong may have a difficult time developing socially. He may be so afraid of displeasing the adults around him that he keeps to himself (where he can’t get into trouble)or he may take the opposite route and go out of his way to create trouble. Like the deserted child, he too may return to infantile (幼稚的)pleasures, developing habits that will satisfy him, but create barriers(障碍)toward social contact.
Which of the following may have effect on children’s paten of social development?

A.Age.      B.Education C.Home life.    D.Gender(性别)

The passage implies that which of the following may have the earliest time learning to get along with others?

A.An only child

A.Too much scolding of children may make their social development difficult.
B.All children developed in the same ways.
C.Children who are constantly scolded may learn to get along with others quickly.
D.Deserted children often exhibit quicker social development.

We can inferred from the passage that ________.

A.continual scolding is not harmful to the child.
B.continual scolding holds back healthy social development.
C.continual scolding has no effect on obeying orders.
D.continual scolding has no effect on physical development

-What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live, Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

-American office workers spend an average of 52 hours a week at their desks, according to a statistic survey. Some might argue that not all that time is spent working,but still all those hours in windowless offices with artificial light can have an influence.
A few green additions could have a large effect on worker happiness,according to the survey led by Tina Cade from Texas State University.
“We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job,” Cade told LiveScience. “We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like building a gym. Maybe for less investment they could put in a few plants in important places.”
The team surveyed 450 office workers in Texas and the Midwest,asking questions about job satisfaction and the work environments. When asked about their overall life quality,82 said they felt “content” or “very happy”. Only 69 percent of those who work with plants but without windows,and 60 percent of those who have windows but no plants, said they felt this way.
The group of people who work without plants or windows were the most dissatisfied,with only 58 percent of them saying that overall they were “content” or “very happy”. While no one who works with plants,windows,or both reported they felt “miserable”, 0.8 percent of those who work in offices without either said they were “miserable”. “I was really surprised that having a plant in your office appeared to be more beneficial than having a window in your office,” Cade said. “Everybody says, ‘I need a window!’ but actually it seemed like a plant could be a suitable alternative.”
What does the passage mainly tell us?

A.Green plants can increase job satisfaction.

-Without proper planning, tourism can cause problems.For example, too many tourists can crowd public places that are also enjoyed by the inhabitants(居民) of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people of a destination(目的地) country and how tourism affects them. Tourism should help a country, keep the customs and beauty that attract tourists.Tourism should also advance the wealth and happiness of local inhabitants.
  Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
  On the other hand, if there is not enough tourism,people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports,air terminals, first-class roads, and other support facilities(设施)needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
  Building a hotel is just a beginning.There must be many support facilities as well,including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.
Which of the following has most probably been discussed in the part that goes before this passage?

A.It is very important to develop tourism.
B.Building roads and hotels is necessary.
C.Support facilities are highly important.
D.Planning is very important to tourism.

Too much tourism can cause all these problems EXCEPT ________.

A.a bad effect on other industries
B.a change of tourists’ customs
C.over-crowdedness of places of interest
D.pressure on traffic

Not enough tourism can lead to ________.

A.an increase of unemployment (失业)
B.a decrease (减退) in tourist attractions.
C.the higher cost of support facilities
D.a rise in price and a fall in pay.

The underlined word “handle” in the last paragraph most probably means _________.

A.get in
B.pick up
C.carry away

-For five days, Edmonton's Downtown Park is transformed into one huge stage where artists are able to share their talents, and where people are able to celebrate(庆祝) and enjoy themselves. Since its beginning in 1980, the Edmonton Folk Music Festival has been commemorating (纪念) the true feeling of what folk music is all about and that's the traditional togetherness that is felt when people gather to share stories and feelings through song.
This year will be the sixth year when volunteer Riedel will be offering up her time to the festival. "People coming off a busy spring and summer have a moment of relaxation," Riedel said. "It's really easy to relax, and it's great seeing family and friends have fun together." These families and friends come from all different kinds of musical tastes. People who take pleasure in Blues are there, so are people who love Bluegrass. This festival does its best to develop everyone's musical interests.
With so many years of experience, the festival has become a well-oiled machine, and does whatever it can to make attendees feel as comfortable as possible. There are free water stations throughout the venue (举办地) for people to fill up their travel cups. When people buy food, reusable dishes are given a $2 plate fee, but that is returned when the plate is brought back.
The festival has completely sold out of tickets, and in record time. But with big names such as Van Morrison and Jakob Dylan, it's easy to see how that was going to happen. There is no parking area during the festival, so using the Park & Ride system or Edmonton Transit is highly recommended. A bike lock-up area is provided and will be available Thursday until Sunday one hour before the gates open until 45 minutes after the gates close.
The Edmonton Folk Music Festival begins on Wednesday, Aug. 4 with Van Morrison playing the special donation fund (基金) concert, and will finish up on Sunday, Aug. 8.
