to see some meateating plants. Take bladderworts (狸藻类植物), a kind of such plant, for example.
They appear so small and grow in a quiet pond. "But these are the fastestknown killers of the plant
kingdom, able to capture a small insect in 1/50 of a second using a trap door! "
Once the trap door closes on the victim, the enzymes (酶) similar to those in the human stomach
slowly digest the insect. When dinner is over, the plant opens the trap door and is ready to trap again.
Meateating plants grow mostly in wet areas with soil that doesn"t offer much food value. In such
conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands
of years. North America has more such plants than any other continents.
Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants,
which get their name because they look like beautiful pitchers (a container like a bottle) full of nectar
(花蜜).
The Asian pitcher plant, for example, has bright colors and an attractive halfclosed lid. Curious insects
are tempted to come close and take a sip, and then slide down the slippery (光滑的) slope to their
deaths.
Hairlike growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes
can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days.
Some of these pitchers are large enough to hold two gallons. Meateating plants only eat people in science
fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn"t a good
place to get a drink.

C. tempting insects to come close

Dear Reader,
Today I am going to ask you to support Wikipedia with a donation.
Wikipedia is built differently from almost every other top 50 website.We have a small number of paid
staff, just twentythree.Wikipedia content is free to use by anyone for any purpose.Our annual expenses are less than six million dollars.Wikipedia is run by the nonprofit Wikimedia Foundation, which I founded in
2003.
Wikipedia is driven by a global community of more than 1
50,000 volunteers-all devoted to sharing knowledge freely.Over almost eight years, these volunteers have contributed more than 11 million articles in 265 languages.More than 275 million people come to our website every month to access information,
free of charge and free of advertising.
But Wikipedia is more than a website.We share a common cause:Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge.That"s our commitment.
Your donation helps us in several ways.Most importantly, you will help us cover the increasing cost of managing global traffic to one of the most popular websites on the Internet.Funds also help us improve the software that runs Wikipedia-making it easier to search, ea
sier to read, and easier to write for.We are committed to increasing the free knowledge movement worldwide, by taking on new volunteers, and
building strategic partnerships with institutions of culture and learning.
Wikipedia is different.It"s the largest encyclopedia (百科全书) in history, written by volunteers.Like
a national park or a school, we don"t believe advertising should have a place in Wikipedia.We want to
keep it free and strong, but we need the support of thousands of people like you.
Thank you,
Jimmy Wales

| The breathless pace of everyday life made many people sleepless, said our reporter Wang Ling, when talking about the World Sleep Day (WSD)with sleep experts in order to find out how to get a better sleep. Cui Shuliang, founder of 51sleep.com, which provides online advice for those yearning for a sound sleep, found many of his workmates suffering badly from poor sleep quality, as an IT technician in earlier times. "Each morning, I would hear complaints from someone that kept waking up during the night, or someone else who had to spend all night fighting for sleep." Pressed by busy city life, more and more people are suffering from sleep problems ranging from insomnia to narcolepsy (嗜眠症). Some people may be able to fall asleep, but spend the whole time in fear. A survey conducted by the Sleep Research Society (SRS) shows that about 40% of the population is troubled by sleep disorders, which can result in lowered awareness and less productive days. Serious insomnia can even lead to psychiatric problems. Professor Zhang Xi, director of the organization, says the focus of this year"s World Sleep Day will be on scientific ways to sleep. Professor Zhang Xi explained that the causes of sleep disorders differ among cases, but more than 80% of his patients had trouble in sleeping because they always have a nervous worried feeling that makes it impossible for them to relax. "That"s why we keep suggesting people pay more attention to sleep problems, since there remains a hidden danger in the physical and mental condition. On the other hand, people with sleep problems should learn how to ease their mind and relax themselves. Staying mentally and physically healthy, plus having healthy habits, is the best way to realize a sound sleep." | |||

| In 2008 and 2009 I published two articles researching a lull (停歇)in solar activity. At the time, there appeared to be some disagreement among scientists as to what effect this might have on humancaused global warming. Now climate scientists agree a less active sun won"t have much of an effect. According to the reports from the IPCC, global climate is expected to warm between 4 and 10 degrees Fahrenheit by the year 2100. On the other hand, scientists show that the reduction in radioactive forcing due to low solar activity would reduce world temperature half a degree F if the lull in solar activity lasted until the end of the 21 century. It is highly unlikely the current lull in solar activity would have such a long period. "It is more likely that a new lull in solar activity would reduce the global temperature average of 0.2 Celsius by the end of 2100," commented Professor Stefan Rahmstorf, who was responsible for a study of a lull in solar activity effects on climate at the Institute for Research on the Impacts of Climate Change in Potsdam. In short, this small forcing is likely to have little, if any, observable effect on humancaused global warming,at most reducing the temperature increase to between 3.5 and 9.5 degrees F. The reason for the small effect on temperature is due to the fact that the difference between solar activity highs and lows changes solar output by less than one half of one percent. So the difference in the amount of energy coming out of the sun between solar highs and lows isn"t very large. The result is that the human forcing on climate is many times larger than that caused by any natural difference in the sun. Generally if humancaused climate_change isn"t controlled it can"t be stopped by natural changes in the sun. | |||
| 1. What once caused the argument among scientists? | |||
| A. The reduction in world temperature. B. That humans are responsible for global warming. C. That humans are stronger than nature. D. Whether the lull in solar activity has effect on humancaused global warming. | |||
| 2. According to scientists, world temperature would fall a little if ________. | |||
| A. less CO2 is given off B. more trees are planted C. redioactive forcing becomes strong D. the lull in solar activity lasts a long period | |||
| 3. What can we learn from the passage? | |||
| A. The author is expert at writing science fiction. B. The current lull in solar activity will last very long. C. The power of humans is stronger than the sun on global warming. D. The IPCC reported that world temperature would fall greatly. | |||
| 4. What do the underlined words "climate change" refer to? | |||
| A. The flood. B. Global warming. C. The earthquake. D. Global environmental change. | |||
| 5. What does the passage mainly talk about? | |||
| A. The effect of global warming. B. An argument among scientists. C. That humans are a cause of global warming. D. That a less active sun cannot stop global warming. | |||

Therefore, wine fatty dairy products, bread, junk food and red meat become an important diet in these countries. However, the blame cannot be entirely put on the unhealthy eating habits of the people. Technology allows them to import almost all the foods products that they do not grow. Although some healthy food are grown in the countries nowadays, the quantity is very limited. It is not enough to meet the demand. So when they are not available and fatty foods are cheaper, then people prefer to go for the eating habit that they have always been following. | |||
