It’s such a common event that you probably never asked yourself why you sleep. ___1____ In fact, for sleep researchers, it’s one of the biggest unanswered questions in the field.
Stop and think about it for a second. Why should we sleep? ____2_____ But we sleep every night, even when we have had plenty of rest. There are,no doubt,several different answers to this question, but let’s just consider one general purpose of sleep: ____3_____ Human beings are creatures that are normally active during daylight hours, when our senses function most effectively. ____4_____ We can’t see objects well, our color vision is entirely lost, and we don’t have the smelling or hearing sharpness of other animals. So it actually does make sense to have us stay where we are during the dangerous period when night-waking animals are walking here and there. And one sure way to make sure we don’t fall down everywhere and get lost or eaten is to have us not move for seven or eight hours, rising again only when the light is back and our survival chances are better.
It’s not the only reason we sleep. ____5____Perhaps even the most important one.
A.Is it because we get tired? |
B.Should that put human beings in a terrible situation? |
C.But from a scientific point of view, this is far from anordinarymatter. |
D.But in terms of evolution, it may have been one of the first reasons. |
F. Sleep as a survival approach.
G. At night, humans do rather poorly.
In the contrary, some other students think that the old buildings may hold back the development of economy and the process of modernization. It may affect the beauty of the city.
As far I’m concerned, I approve of(赞成) the former opinion. But if a building is worth of little, it may be proper to demolish(摧毁) it and make better use of that area. We should just weight the advantages and disadvantages.
What is happiness? 小题1: people have different ideas. Some people are rich; they think they are happy. 小题2: people have many friends, so they feel 小题3: . Still others are happy because their lives are meaningful. Happiness attracts everyone. For children, happiness often suggests eating something good or 小题4: with toys. 小题5: a stamp collector, stamps bring more delight than meals. And for a scientist, a discovery or an invention rather than 小题6: else gives him greatest satisfaction. As everything exists only because of its opposite, happiness exists only when 小题7: exists. Just as a person who does not know failure never knows success, a person, who has not experienced suffering or sadness never knows 小题8: happiness means. Cheer up and be happy. Happiness is not far from you. It’s just around you. Try to grasp it and enjoy it.
The World Bank, the United Nations and the London School Of Hygiene and Tropica1 Medicine did a study to urge hand-washing around the world. They found that one million lives could be saved each year if people washed their hands with soap often. They said that programs to increase hand-washing with soap could be among the most effective ways to reduce infectious disease.
Doctors say, many diseases can be prevented from spreading by hand-washing. These include pinworms (寄生虫), influenza (流行性感冒), the common cold, hepatitis (肝炎) A, meningitis (脑膜炎) and infectious diarrhea (腹泻).
Hand-washing destroys germs from other people, animals or objects a person has touched. When people get bacteria on their hands, they can infect themselves by touching their eyes, nose or mouth. Then these people can infect other people.
The experts say the easiest way to catch a cold is to touch your nose or eyes after someone nearby has sneezed or coughed. Another way to become sick is to eat food prepared by someone whose hands were not clean.
The experts say that hand-washing is especially important before and after preparing food, before eating and after using the toilet. People should wash their hands after handling animals or animal waste, and after cleaning a baby. The experts say it is also a good idea to wash your hands after handling money and after sneezing or coughing. And it is important to wash your hands often when someone in your home is sick. The experts say the most effective way to wash your hands is to rub them together while using soap and warm water.They say you do not have to use special antibacterial soap. Be sure to rub all areas of the hands for about ten to fifteen seconds. The rubbing action helps remove germs. Then rinse (冲洗) the hands with water and dry them.

As the United Nations climate change conference in Copenhagen enters the homestretch(最后阶段), government leaders, heads of international organizations, and academics gathered at a side event to debate China’s political and economic shift towards a low carbon model of growth. The event drew upon the previous results of China’s oncoming 2009/10 National Human Development Report (NHDR), entitled, China’s Pathway Towards a Low Carbon Economy and Society.
The China NHDR 2009/10 is developed by UNDP China and Renmin University. One of the many interesting findings of this report suggest that some of the more economically advanced provinces in China are the least carbon intensive (密集的) while those which have a lower income and lower human development indicators have higher carbon emissions (排放) patterns. This indicates that human development does not necessarily need to be accompanied by increases in greenhouse gas emissions. A more sustainable and low carbon development path, and one which is consistent with advancing human development goals, is indeed possible. While past economic and social progress in China and elsewhere has come at a certain cost, including to the environment, future developments can follow a different path.
Khalid Malik, UN Resident Coordinator and UNDP Resident Representative in China, stressed UNDP’s obligation to helping further China’s progress towards a low carbon model. “UNDP is cooperating with China in dealing with the challenges of climate change and working towards a green economy, a low-carbon economy, and a circular (循环的) economy. We are doing this by, for instance, promoting energy efficiency in industry and buildings, and supporting the fulfillment of the National Climate Change Policy at the local level,” said Malik.
“As it plays an ever more important part in global affairs, China can also play an increasingly important role in advancing sustainable development around the world. China also has the experience and technology available to address challenges in other developing countries, including those related to adapting to and reducing climate change,” commented Clark.
Following the discussions, panelists (与会者) participated in a bicycle ride to highlight the importance of using environmentally friendly transportation and advocate for simple solutions to low carbon development.
1. Why did the leaders and the academics gather on the homestretch in Copenhagen? (no more than 14 words)
2. Which places have higher carbon emissions? (no more than 7 words)
3. How is the role of China in Global affairs according to the text? (no more than 3 words)
4. What did the panelists do to advocate for simple solutions to low carbon development? (no more than 7 words)
