Common indoor plants may prove to be a valuable weapon in the fight against risi

NASA have announced the finds of a 2-year study that suggested the common indoor plants may provide a natural way of helping fight against “Sick Building Syndrome(综合症)”.
Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wloverton, a senior research scientist at NASA.
Based on preliminary evaluations(初步评估) of the use of common indoor plants for indoor air purification(净化),NASA funded a study using about a dozen popular varieties of attractive plants to determine their effectiveness in removing several key pollutants linked with indoor air pollution. NASA research on indoor has found that living plants are so efficient at absorbing pollutants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations.
While more research is needed, Wolverton says the study has shown that common indoor plants can remove certain pollutants from the indoor environment. “We feel that future results will provide an even stronger argument that common indoor plants can be a very effective part of a system used to provide pollution free homes and work places,” he concludes.
“Combining nature with technology can increase the effectiveness of plants in removing air pollutants,” he said.
NASA research has always shown that living, green and flowering plants can remove several poisonous chemicals from the air inside buildings. You can use plant in your home or office to improve the quality of the air to make it a more pleasant place to live and work—where people feel better, perform better, and enjoy life more.

A few months later the doctor removed not only the tumour（肿瘤）, but also the entire lower left side of Betty’s gum（牙龈）and jawbone. Because Betty was so young, Martin was hopeful that her jawbone might regenerate.
Within three months, Betty’s tumour grew as large as an orange, changing the natural appearance of the left side of her small, delicate （ =" thin;" not strong）face. Soon she couldn’t even close her mouth, and as her eating problems worsened, Betty ‘s weight dropped from 20 kilos to 15. Martin knew from experience that it might invade the brain.
The only other possibility was thorough radiation therapy （放射疗法）. Night after night, Betty"s father gave her injection, but the tumour remained as big as ever. Then one evening. Morgan noticed that the tumour had begun to change. It was actually becoming smaller! For two months her tumour appeared to be going away for ever. In the coming months, Betty’s tumour continued to appear. She was able to eat solid food once again. Her jawbone was regenerating. The tumour was gone.

Some deep thought in us know that when 43 a small mistake has been made, your 44 will stay out of balance until the mistake is acknowledged and your regret is 45 .
I remember a doctor friend, 46 me about a man who came to him with 47 illnesses: headache, insomnia（失眠）,stomachaches and so on. No physical 48 could be found. Finally the doctor said to the man,“ 49 you tell me what’s on your conscience（良心）,I can’t help you.”
After a short silence, the man told the doctor that he 50 all the money that his father gave to his brother, who was 51 His father had died, so only he himself knew the matter.

A study of the effects of alcohol on the middle aged and elderly found the average IQ of men who drink wine (whether made from grapes or rice) was 3.3 points higher than that of men who do not imbibe.
Similarly,the IQ of women drinkers showed an improvement of 2.5 points over their teetotal sisters.The findings are part of an ongoing study by Japan’s National Institute for Longevity into the links between human intelligence and what we eat and drink.
The tests measured general knowledge,powers of judgment and concentration in drinkers and non-drinkers over 40,all living in Aichi prefecture,central Japan,and sharing the same income level-roughly￡50 000 a year—and educational background.All were university graduates.
But while wine-drinkers appeared to be brighter,the same was not true of those who drank deer,shochu (a local gin) and whisky.
“The benefits of wine and sake (rice wine) in raising IQ could be due to substances they contain,such as polyphenol,which are believed to slow the ageing process,” Hiroshi Shimokata,head of epidemiology research,said.
It was premature to conclude,he added,that drinking wine or sake slowed the deterioration of brain functions in the elderly,or warded off senility.The research does,however,suggest that this is one way to stay mentally alert longer.
But there is a sobering caveat:drinking too much may make you dimmer.“People who drink more than 540 milli-litres (a little over a pint) of sake or wine a day had lower intelligence quotients than those who did not drink at all,”Hiroshi Shimokata said.“Moderation is very important.”
小题1:Which one is the topic of the passage?
| A．Drinking wine in a large amount improves the IQ of old people. |
| B．Drinking wine in a reasonable amount raises the IQ of old people. |
| C．Drinking wine in moderation does good to any one. |
| D．Drinking wine helps improve the IQ of women. |
| A．Every wine drinker’s IQ is 3.3 points higher than that of men who don’t drink. |
| B．The IQ of women drinker is 2.5 points lower than that of the non-drinking women. |
| C．Drinking beer and whisky cannot improve one’s IQ. |
| D．Drinking wine can only do good to the IQ of rich old people. |
| A．wine and sake have special taste |
| B．wine and sake can make us excited |
| C．wine and sake contain substances considered to slow the ageing process |
| D．wine and sake contain something believed to prevent us from ageing |
| A．the more wine we drink,the brighter we are |
| B．the less wine we drink,the brighter we are |
| C．drinking wine less than 540ml a day,we’ll become dimmer |
| D．drinking wine in moderation,we’ll become brighter |
If you were to eat more than 1800 calories per day,the surplus turns into fat.It takes about 3600 excess calories to make a pound of fat.Let"s say that you were to eat,on average,2000 calories per day.That extra 200 calories per day is going to turn into fat.However,you will eventually hit a point of equilibrium(平衡，均衡) because as you gain weight,you need more calories to maintain that weight.So,a person eating an average of 2000 calories per day will hit equilibrium at (2000/12) 166.67 pounds.
So let"s say that you eat,on average,2000 calories per day and reach equilibrium at 166 pounds.Then you go on a crash diet where you eat only 1000 calories per day for 60 days.You lose 16 pounds and reach your target weight of 150 pounds.But then you go right back to eating 2000 calories per day again.The graph below shows your eating pattern before,during and after the diet:
Note that the graph assumes that you,like most people,eat a random number of calories per day.Some days you are “good” and eat less,and some days you are “bad” and eat more,but the assumption is that it averages out to 2000 calories per day over the long run.
This graph shows what happens to your weight before,during and after the diet:
The diet really takes the weight off.But the weight comes right back when you return to your “normal” eating pattern.The weight appears to come back so quickly because when you are at your lightest,you tend to gain more weight each day.The lighter you are,the fewer calories you need.If you only need 1500 calories per day and you"re eating 2000,you"re going to gain weight faster than if you need 1800 and you"re eating 2000.
小题1:The passage is mainly about_________.
| A．how to lose weight effectively |
| B．why the weight comes back so quickly once a person stops dieting |
| C．why a person puts on weight |
| D．how to keep a healthy diet |
| A．1440 | B．1800 | C．2000 | D．1000 |
| A．A person who weighs 200 pounds. | B．A person who weighs 180 pounds. |
| C．A person who weighs 150 pounds. | D．A person who weighs 100 pounds. |
| A．Ways to keep the weight off. | B．Ways to go on a diet. |
| C．Diseases caused by overweight. | D．Proper diet to keep healthy. |
