题目内容
Living in a modern society with more and more out-of-date but still useful computers, many people have to face such a troubling problem: How to deal with those old computers? Some old ones are put away in homes. Many more are just thrown out with the rubbish.
Don’t worry! Some companies are coming up with new ways to cut the number of old computers. Sony, Dell, Hewlett-Packard and other companies now agree to take back some old computers.
In some countries, there are laws about what to do with old computers. By law, computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.
While many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（组织）are working to solve this problem. They collect and repair old computers before sending them to schools, charities（慈善团体）and people who need them. In this way, we can turn one person's rubbish into someone else's useful things-and cut down on waste.

孟建平小学滚动测试系列答案Robert Frost was one of America’s best known and most honored serious writers. But his fame came late in his life.
He was born in San Francisco, California in 1874. He lived in California during his early childhood. He was named after the chief Southern general in America’s Civil War. The general’s name was Robert Edward Lee. The poet was named Robert Lee Frost, because his father wanted to honor the general.
Someone once asked another American writer, Ernest Hemingway, how to become a writer. The best thing, he said, was to have an unhappy childhood. If this is true, Robert Frost’s childhood was unhappy enough to make him a very good writer. Robert Frost’s father was a reporter who wanted to be a politician. He often drank too much wine and became angry. Robert was the victim (受害者) of his anger.
Robert Frost finished high school in 1891. After high school, Robert’s grandfather offered to pay his costs at Dartmouth College. But Robert left the school after a few months. He did not like it. He spent the next few years working at different jobs. At one time, he worked in a factory. Later, he repaired shoes. He was a teacher. He was a reporter. Always, he wrote poetry.
Robert Frost attended Harvard University for two years. After that, he returned to the many jobs he held before. For a while, Frost tried to take care of a farm in the state of New Hampshire. He was not a successful farmer. And he continued to write poetry. He said that until 1930, he earned only about ten dollars a year from writing.
In 1912, he decided to try to make a new start. He took his family to Britain. The cost of living was low. In Britain, Frost found a publisher for his first book of poems. The book was called A Boy’s Will. When it appeared in 1913. Frost received high praise from British readers. Praise was something he had not received in his own country.
Ezra Pound, another American poet living in Britain, read the poems and liked them very much. He wrote a magazine article about Frost. He also helped get Frost’s second book of poems published in America. That book was called North of Boston.

Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being very overweight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts （内脏）when you were a baby and the chance that you would become overweight?
Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.
You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.
Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.
So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.
【小题1】The “link” in Paragraph 2 refers to the relationship between _______.
| A．bacteria and the chance of being overweight | B．obesity and diabetes |

| B．analyze the influence of obesity on kids |
| C．give advice on how to lose weight quickly |
| D．explain the function of bacteria in foods |
A team of US psychologists have found that talking to another person for ten minutes a day helps with memory.
"Socializing is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement.
In one investigation, they analyzed data on 3610 people, aged 24 to 96.
They found that the higher their level of social interaction (交流), the better their cognitive (认知的) functioning. Social interaction includes getting together or having phone chats with relatives, freinds and neighbors.
In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests.
The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group (对照组) watched a 10-minute clip (电源片段) of the Seinfeld television show.
"We found that short-term social interaction lasting for just 10 minutes improved participants’ intellectual performance as much as engaging in so-called ’intellectual’ activities for the same amount of time," Ybarra said.
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin.
