Play games
Your brain is a muscle just like the ones in the rest of your body. If you don’t use it, you will lose it. For example, doing a crossword puzzle (纵横填字游戏) once a day is a good way to give the brain the exercise it needs. This kind of puzzle is good at training different areas of the brain. But remember that when doing this puzzle, you should gradually increase the complexity (复杂度); otherwise, it will become repetitive (重复乏味的) and stop being mentally challenging.
Talk aloud
Although it might sound strange to you, talking aloud is a great way to boost your memory. A good exercise to try is counting to 99 in threes as fast as you can.
Be a team leader
If you find you can do your work very easily, you should find a new task. It is important that your job should be mentally challenging. Complex jobs are often more challenging and make the brain work a little harder.
Learn a language
A study found that, compared with those who could speak only one language, the people who could speak two languages had a slower rate of cognitive (认知能力) decrease. Learning a new language is very challenging and it makes sure that different areas of the brain have their lights on.
小题1:What is the main idea of this passage?
| A．Why you should train your brain. |
| B．How to be a good team leader. |
| C．Training the brain is more important than training the body. |

举一反三
Once inside，the cow is rewarded with food．As the cow eats，a robotic arm cleans and connects the animal to the milking machine．A few minutes later，milking is complete．The gate is opened，the cow is released and the next cow enters．
The robotic systems are designed to operate 24 hours a day．The cows get to decide when they want to be milked．Cows are milked an average of about three times a day．Some are milked four to six times a day．
The cows wear collars around their necks that identify them to the system．A computer keeps records on their eating and milking．A cow is released from the station if the computer decides it should not be milked．
The automated system also measures the temperature and color of freshly produced milk．Milk is thrown away if it does not pass the tests．
Professor Plaut believes the systems will appeal（吸引） especially to the next generation of farmers．She means young people who are more interested in technology and less interested in working all the time on the farm．Still，she says the price of robotic milking systems will continue to limit their use．
Doug and Tina Suhr have more than 100 cows on their family farm．Last year it became the fourth farm in southeast Minnesota to get a robotic milking system．A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars．The second cost 150 000．
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot．He says the increase in milk production reaches a high of more than six kilograms per cow per day．
小题1:From the first paragraph，we can infer________．
| A．the robotic system is designed to reduce labor |
| B．cows can be raised by robots in the future |
| C．robots direct cows into milking stations |
| D．cows are kept clean by robots on some farms |
| A．adjust the temperature of milking stations |
| B．judge the quality of fresh milk |
| C．improve the appetite of cows |
| D．keep fresh milk for two weeks |
| A．Because young people have no interest in it． |
| B．Because it is difficult to learn how to use it． |
| C．Because people can’t afford to buy it． |
| D．Because it usually causes the waste of milk． |
| A．150 000～170 000． | B．750 000． |
| C．150 000～30 000． | D．30 000—32 000 |
| A．Letting robot milk your cow | B．Milking cows by hand |
| C．Improving the quality of milk | D．Drinking fresh milk every day |
LONDON (Reuters) ----- Dealing with the dissatisfaction of aging and unreliable office computers leads to workers" unhappiness and more sick leave, a survey showed on Wednesday.
A survey carried out by caro4free.net of over 2,700 European office workers from the UK, France and Germany found that workplace dissatisfaction increased greatly with the age of the computer equipment.
"We do know that job satisfaction is falling in Britain and most advanced nations," said Stephen White, a researcher from the Work Foundation. "The actual reasons for this are the subject of very heated discussion. It"s certainly one interesting theory that technology may be the cause of this in some way," White added.
A quarter of these using outdated computers in Britain said they were "quite" or "very dissatisfied" with their everyday job compared to the percent of those who had enjoyed an advantage from up-to-date technology.
The survey also said that among workers dealing with outdated equipment, there was a 35 percent greater probability they would take six or more days of sick leave per year compared with the average worker. In France, where more workers use old computers, the probability jumped to 55 percent.
Results also showed that women in the three countries were more likely to be using outdated equipment. In the UK, where more workers have up-to-date computers than in the other countries surveyed, the number of women using old equipment doubled that of men.
White pointed out that there were two sides to this problem, saying that continuously having to deal with new technology and equipment can also be a source of worry. "Old and faulty equipment is a major cause of office dissatisfaction. There is no question about it; but you also have to say that the frequent change of equipment is also, or could be, a main cause of dissatisfaction."
小题1:The underlined word "this" (paragraph 3) refers to ______.
| A．workplace dissatisfaction | B．computer use in most jobs |
| C．the aging off office computers | D．the survey by care4@ free. net |
| A．16% | B．25% | C． 35% | D．55% |
| A．Most office workers use old computers. |
| B．They do some of their work with computers. |
| C．Dealing with new equipment can cause anxiety. |
| D．They are easier to be satisfied with new technology. |
| A．Poor working conditions in offices |
| B．Research work of the Work Foundation |
| C．Influence of technology in the workplace. |
| D．Different attitudes to old computers. |
Show them the future. If your 13-year-old girl were to save $1.000,invest(投资)it at 8% and add $100 every month, by the time she"s 65,she would have $980,983!
Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history, but they must be used responsibly, which means paying off your debt in time. Explain to your children that when you buy something using a credit card, you can easily end up paying two or three times what you would have paid if you used cash.
Teach patience. Suppose your child wants a new bicycle that costs $150.Rather than paying the cash, give him some regular pocket money and explain that by putting aside,say,$15 each week, he will be able to buy it for himself in only ten weeks.
Provide incentive. Tell your children the importance of saving. "For every dollar he or she agrees to save and invest rather than spend, you agree to add another dollar to the pot, "says Cathy Pareto, expert in money planning.
Explain your values. Values and money are deeply intertwined(缠结在一起), says Eilleen Gallo, co-author of The Financially Intelligent Parent. When your child demands that you buy something, explain why you really don"t want to buy it. "You might say, "I"d rather save that money for your education,"" advises Gallo. Every time you spend or don"t spend money, you have a chance to share your values.

B. He wants to share his good ideas about money matters.
C .He thinks money management the most important for children.
D. Parents care little about their children"s management of money.
Textbook prices are traditionally high．Adding to that problem，many college teachers change textbooks year after year；they either upgrade to a new edition or switch to an entirely different textbook．This further hurts students because if an instructor no longer uses a particular textbook，that book has no resale value．
Dr．Jason decided to make lire a little easier and a lot cheaper for his students by writing his own book on public speaking．“Many books have an increased price because of CD-ROMs，lots of color photographs and pictures．I talked to my students，and many of them，like me，prefer to keep things simple! So，a few years ago，I wrote my own textbook．Compared to most other public speaking books，mine is half the number of pages，and one-third the price．That is，$30 instead of $90．When I wrote a second edition last year，students only had to buy the 35 new pages, For only $7．00，they had almost a new book. Now my loose-leaf textbook enjoys great popularity among the students．Maybe in the future more writers and publishers will try it．”

| C．To speak to his students. | D．To use old textbooks． |
| A．About 7 dollars. | B．About 30 dollars. |
| C．About 37 dollars． | D．About 90 dollars． |
| A．Dr Jason"s textbook has CD-ROMs and nice pictures. |
| B．More writers and publishers will write simpler textbooks． |
| C．Dr．Jason teaches public speaking at a college． |
| D．Dr-Jason’s textbook is not well received． |
Decibels(分贝) measured in water are different from those measured on land. A noise of 120 decibels on land causes pain to human ears. In water, a decible level of 195 would have the same effect.
Some scientists have suggested setting a noise limit of 120 decibles in oceans. They have observed that noises above that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing, which seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected(感染的).
Many researches whose work depends on ocean sounds disagree with a limit of 120 decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how many and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they previously believed. They want to prevent noises from harming creatures in the ocean.
小题1:The second paragraph mainly tells us that the noises on land and in water .
| A．are both from human activities. |
| B．both do harm to sea animals |
| C．are measured differently |
| D．have the same effect on humans |
| A．They are deaf to noises. |
| B．Noises at a certain level may hurt them. |
| C．They are easily confused by noises. |
| D．Noises will limit their ability to reproduce. |
| A．protect whales from noises |
| B．benefit them a lot in their research work |
| C．do good to their health |
| D．increase industrial output |
| A．Count the number of sea animals. |
| B．Stop their research on the ocean. |
| C．Study the effect of different noises. |
| D．Protect sea creatures from harmful noises. |
