New research suggests that speaking more than one language may delay different kinds of dementia(痴呆), that is the loss of mental ability. In fact, researchers say, speaking two languages appears to be more important than the level of education in defending against dementias.
A study in India examined the effect of knowing more than one language in delaying the first signs of several dementias. Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, the most common form of mental decline(下降). 391 of the subjects spoke two or more languages. Researchers found the dementias began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language. The level of education had no effect on the age at the first sign of dementia.
Thomas Bak, from the Center of Cognitive Aging at the University of Edinburgh in Scotland, who helped to organize the study, suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions. He also believes this effort improves what scientists called executive(执行的) functioning, which often weakens in people with dementias. He states that researchers found there was no extra gain in speaking more than two languages.
Mr Bak says it does not appear important whether you learn another language at a young age or later in life. It's not something that “you missed the boat when you do not do it as a baby.” It is something that is still quite useful and powerful when you do it as an adult. The finding of the study is that________.
| A．learning more than one language can cure dementias |
| B．speaking two languages may delay kinds of dementias |
| C．the level of education matters in defending against dementias |
| D．people who suffer from dementias will lose mental ability |
The underlined word “subjects” refers to________.
| A．people who were studied in the study |
| B．notices that were put on about the study |
| C．questions that were asked in the study |
| D．methods that were used in the study |
According to Mr Bak, ________.
| A．the more languages one speaks, the less chance of getting dementias |
| B．people’s executive functioning often strengthens with age |
| C．when you learn one more language makes no difference |
| D．it is much easier to learn one more language at a young age |
This passage may probably be seen in________.

Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir (知识库) which may be called experience, and the college students will find that every craftsman (工匠) has something he can teach and will generally teach gladly to any college student who does not look down upon them. The information from them differs from that in textbooks and papers chiefly in that its theoretical (理论的) part -- the explanations of why things happen -- is frequently quite fantastic (神奇的) . But the demonstration (示范) and report of what happens, and how it happens are correct even if the reports are in completely unscientific terms. Presently the college students will learn, in this case also, what to accept and what to reject. One important thing for a college student to remember is that if Aristotle could talk to the fisherman, so can he.
Another source of knowledge is the vast store of traditional practices handed down from father to son , or mother to daughter, of old country customs ,of folklore (风俗). All this is very difficult for a college student to examine, for much knowledge and personal experience is needed here to separate good plants from wild grass.The college students should learn to realize and remember how much of real value science has found in this wide, confused wilderness and how often scientific discoveries of what had existed in this area long age. In the last paragraph the phrase "this wide, confused wilderness" refers to _____.
| A．personal experience |
| B．wild weeds among good plants |
| C．the information from the parents |
| D．the vast store of traditional practices |
Which of the following statements is supported by the passage?
| A．The college students have trouble separating good plants from wild grass |
| B．Craftsman’s experience is usually unscientific |
| C．The contemptuous (傲慢的) college students will receive nothing from craftsmen |

| A．be contemptuous to the craftsman |
| B．be patient in helping the craftsman with scientific terms |

Thirty years ago not many people would have dreamed of doing the repairs and decorations in their own homes. In those days labor was fairly cheap and most people would have thought it worthwhile to employ a professional painter and decorator, unless of course they were either very hand up or were in the trade themselves. Today, however, it is quite a different story. Men and women in all walks of life turn their hands to all sorts of jobs round the house including painting, papering, putting up shelves and wall units, and tiling walls and floors. Some people with no professional training of any kind have even successfully built their own houses. These jobs have been made easier today by the introduction of prepared materials, which require the minimum amount of skill to use. In every high street throughout Britain nowadays there is at least one “Do-it-Yourself” shop containing a vast range of timber, tiles, paints, wallpapers and floor coverings besides tools of every description including power drills and many accessories. “Do-it-Yourself” is a booming business; all these shops do a roaring trade and look like continuing to do so. Probably the main reason for the craze is the high cost of present-day labor and the shortage of building firms willing to do small jobs. Why did people employ professional workers to decorate homes thirty years ago?
| A．Because they could not do it themselves. |
| B．Because professional workers were very cheap. |
| C．Because they had no time. |
| D．Because professional workers could do much better. |
Thirty years later what changes took place?
| A．People could do everything themselves. |
| B．Few people chose to be a professional worker |

Internet dating has become one of the biggest and most successful business ventures on the Internet. Basically, Internet dating is a way to meet people for either friendship or dating without actually having to meet them in person first.
The first thing to do if you decide to try Internet dating is to build your profile(简介) which can include your hobbies, hopes for the future, and so on.

Many Internet dating sites will charge a one-time registration(注册) fee to use their services.
Internet dating makes it possible to meet people from all over the world. You can even narrow the search down to your area by zip code. Another advantage is that you can communicate by email before you meet in person. Thousands of people have met, fallen in love, and married through Internet dating.

Just as in conventional(传统的) dating and love, there are some pitfalls to be aware of in Internet dating. The person you have been talking to on the net may not be who they say they are.

They call him at six in the morning, after breakfast his father takes him to school in a car and in the afternoon, as soon as the young man comes back, the supper is ready. Of course, he never washes his clothes or goes to buy something in the shops.
Once, Harry’s father was sent to London on business. He would stay there for half a year. Leaving, he told his wife to take good care of their son.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质), like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
