Many parents watch the news or other shows as children play nearby. But new research shows that even when the television is just background noise，it may be disruptive to a child’s normal development.
It’s estimated that 75 percent of very young children in the United States live in homes where the television is on most of the time，even though the kids often aren’t watching it. The University of Massachusetts researchers recently studied how TV background noise might affect young children. The study looked at 50 1，2and 3yearolds. Each child came to a lab with a parent and was allowed to play for an hour with various toys. For half the time，a television was on in the room，showing the adult game show as well as advertisements. During the other half hour，the TV was turned off.
As expected，the children paid little attention to the adult television show，glancing at it for less than a few seconds at a time，and less than once a minute. Even so，the distraction (分心) of the background noise had a significant effect on how children at every age played. When the television was on，the children played with each toy for far shorter periods of time，and focused attention during play was also shorter compared to how they played when the TV was off.
Researchers said that even though the children aren’t interested in the show，background TV affects their ability to do various types of play. The finding is important because many wellmeaning parents who wouldn’t let their young children watch television may not realize that even adult programs that don’t interest children still can have an effect.
“Background TV is potentially a chronic (长期的) environmental risk factor affecting most American children，” said the lead author of the study. “Parents should limit their young children’s exposure (接触)．”We know from the passage that________.
| A．background TV noise has little effect on adults |
| B．most young children in America live in homes exposed to TV noise |
| C．the effect of background TV noise on children is immediate |
| D．most parents in America wouldn’t let their children watch TV |
The underlined word “disruptive” in Paragraph 1 is closest in meaning to________.
| A．harmful | B．important | C．similar | D．related |
In the study，the children________.
| A．were all 3yearolds | B．were asked to watch adult TV shows |
| C．played for an hour while the TV was on | D．played with more than one toy |
What does the study show?
| A．Children pay much attention to adult TV shows. |
| B．Children should be allowed to watch TV for kids only. |
| C．The background TV noise affects children’s ability to focus. |
| D．The more toys a child has，the shorter time he plays with each one. |
Every weekend, many Americans drive around looking for things to buy. They are taking part in an unusual kind of outdoor treasure hunt: the yard sale (旧货出售). In some parts of the country, such a sale might be called a garage sale or a moving sale. Whatever the name, the activity is the same. People sell things they no longer want.
The sellers put a paid announcement in a local newspaper. It tells when and where the yard sale will take place. It lists some of the things to be sold. Early in the morning, all the things to be sold are carried out of the house. Then they sit all day waiting for someone to take them home. Usually, the seller puts a price on each object at a yard sale. However, that price can almost always be negotiated (谈判).
Serious buyers also spend time getting ready for yard sales. They collect the newspaper announcements. Then they make lists of the sales they want to attend.
Most people who go to yard sales are not looking for anything special. They might buy an object simply because it costs so little. They enjoy bargaining over prices, even if they may hold their own yard sale to sell all the things they have bought.
To other people, yard sales are simply a way to have fun. In some communities, they are important social gatherings. Other people say yard sales help the environment. Old things are re-used instead of being thrown away.
In any case, yard sales are very popular in America. Hunting for unusual items is a sport for some people. For others, it is a way of life.

Several southwestern provinces in China are now experiencing the worst drought(旱灾) since the 1950s. The drought has left 18 million people and 11 million farm animals in Yunnan, Guangxi, Sichuan and Chongqing without enough water supplies. And it has affected 5 million hectares of crops in the provinces.
According to China’s Meteorological Administration (中国气象局), the average daily temperature in Yunnan over the past six months has been two degrees higher than normal. And the province has had only half the rainfall of an ordinary year. In Qinglong county, Guizhou, there had been no rain for 268 days until March 25, when it finally rained for three hours.
To ensure the safety of drinking water, local governments have taken emergency action. Workers in parts of Yunnan are drilling (钻空) daily in the hope of digging 1035 wells by mid-May. Among them, 52 have already started working and 288 are under way, providing 20 percent of the required drinking water. Meanwhile, Yunnan province intends to send more migrants (农民工) to work outside the province as the drought worsens. This will not only help to deal with the drinking water shortages, but also increase those farmers’ income. The government will offer free skill training and organize job fairs.

We can achieve knowledge either actively or passively（被动地）. We achieve it actively by direct experience, by testing and proving an idea, or by reasoning.
We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. Conditioned as we are to passive learning, it’s not surprising that we depend on it in our everyday communication with friends and co-workers.
Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is little more than hearsay and rumor(谣言).
Did you ever play the game Rumor? It begins when one person writes down a message but doesn’t show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn, whispers it to still another, and so on, through all the people playing the game. The last person writes down the message word for word as he or she hears it. Then the two written statements are compared. Typically, the original message has changed.
That’s what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a story, trying to improve on it, stamping（打上标记）it with their own personal style. Yet those who hear it think they know.
This process is also found among scholars and authors: A statement of opinion by one writer may be re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts.
57. According to the passage, passive learning may occur in _______.
A. doing a medical experiment B. solving a math problem
C. visiting an exhibition D. doing scientific reasoning

C. communication D. passive learning
59. The author mentions the game Rumor to show that _____.
A. a message may be changed when being passed on
B. a message should be delivered in different ways
C. people may have problems with their sense of hearing
D. people tend not to believe in what they know as rumor
60. What can we infer from the passage?
A. Active learning is less important.
B. Passive learning may not be reliable.
C. Active learning occurs more frequently.
D. Passive learning is not found among scholars.
Now more and more students become volunteers. The projects may be with their school, neighborhood, or town, but the work of all volunteers is important. Students find that there are many advantages to volunteering.
First, volunteering helps others. Many people complain about problems in our society. Volunteers are part of the solution to our problems! While it is easy to complain about things that are not right, the volunteer takes action rather than complaining. When a student spends time working at a retirement (退休) home, cleaning up a park, or teaching a younger student, the volunteer makes the world a better place.
Second, being a volunteer makes students feel good about themselves. When a student volunteer knows that his or her efforts have made someone else’s life better, the volunteer feels great. Students always hear people saying that everyone should care about other people. Volunteers make it happen. Although some volunteer work is long or tiring, student volunteers end the day knowing they did the right thing. Their parents, teachers, and the public are proud of them. Knowing they did the right thing makes them feel better, even if they are tired.
Finally, students learn that volunteering is fun. A group of students might volunteer to clean up a riverbed in early spring. It is fun to be with their friends, to enjoy the weather, and to picnic later in a beautiful, clean area. Other students might read to young children in a playgroup. It is fun to spend time with children and to have them smile and laugh. No matter what their ages or talents are, every student can be a volunteer. The work of student volunteers is a powerful force that makes the world a better place.

One morning a few years ago，Harvard President Neil Rudenstine overslept. For this busy man，it was a sort of alarm: after years of non-stop hard work，he might wear himself out and die an early death.
Only after a week's leave—during which he read novels, listened to music and walked with his wife on a beach—was Rudenstine able to return to work.
In our modern life, we have lost the rhythm between action and rest. Surprisingly, within this world there is a universal but silly saying:“I am so busy.”
We say this to one another as if our tireless efforts were a talent by nature and an ability to successfully deal with stress. The busier we are, the more important we seem to ourselves and, we imagine, to others. To be unavailable to our friends and family, and to be unable to find time to relax—this has become the model of a successful life.
Because we do not rest, we lose our way. We miss the guide telling us where to go, the food providing us with strength, the quiet giving us wisdom.
How have we allowed this to happen? I believe it is this: we have forgotten the Sabbath, the day of the week—for followers of some religions—for rest and praying. It is a day when we are not supposed to work, a time when we devote ourselves to enjoying and celebrating what is beautiful. It is a good time to bless our children and loved ones, give thanks, share meals，walk and sleep. It is a time for us to take a rest, to put our work aside, trusting that there are larger forces at work taking care of the world.
Rest is a spiritual and biological need；however，in our strong ambition to be successful and care for our many responsibilities，we may feel terribly guilty when we take time to rest. The Sabbath gives us permission to stop work. In fact, “Remember the Sabbath ”is more than simply permission to rest；it is a rule to obey and a principle to follow.
50. The “alarm” in the first paragraph refers to “______”.
A. a signal of stress B. a warning of danger
C. a sign of age D. a spread of disease
51. According to Paragraph 4,a successful person is one who is believed to ____.
A. be able to work without stress B. be more talented than other people
C. be more important than anyone else D. be busy working without time to rest
52. Some people feel guilty when taking time to rest because they ____.
A. think that taking a rest means lacking ambitions
B. fail to realize that rest is an essential part of life
C. fail to realize that religions force them to rest
D. think that taking a rest means being lazy
53. What is the main idea of this passage?
A. We should balance work with rest.
B. The Sabbath givers us permission to rest.
C. It is silly for anyone to say “I am so busy.”
D. We should be available to our family and friends.
