　　There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources (能源), such as coal,oil and gas. The trouble with these sources, however, is that they are not renewable.

　　Another way is energy conservation (节能), which means using energy more efficiently (有效地). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.

　　Finally, renewable energy sources are used even though they are often expensive to develop. One form of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometre down. At six kilometres, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped (压, 抽)down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.

(1)How many ways of dealing with the energy problem are discussed in the text?

[　　]

(2)From the text we learn that coal ________.

[　　]

A．is quite easy to produce

B．is not used most efficiently

C．is the most common source of energy

D．could be renewed only by new technology

(3)The writer tells about the “special houses” because they ________.

[　　]

A．show the excellent skills of the builders

B．serve as an example of energy conservation

C．are heated by different sources of energy

D．are warmer than other types of houses

(4)The underlined words geothermal energy in the third paragraph mean

______.

[　　]

A．renewable source

B．underground source

C．heat inside the earth

D．temperature of the earth

(5)Which of the following drawings shows the right way to get geothermal energy?

[　　]

(6)At a place where surface temperature is 15℃, how deep do you have to dig so as to get a temperature of 75℃?

China is working hard to deal with the contaminated(被污染的)milk products scandal（丑闻）, which has so far left four babies dead, a senior official with the World Health Organization (WHO) said on Sunday.
Dr Shigeru Omi, director of the WHO Western Pacific regional office, told a press conference that China is taking the issue "seriously".
"After admitting the problems, the Chinese government is very serious about the matter and I hope the situation will be brought under control as soon as possible," Omi said.
The WHO is assisting China in looking into the scandal but will not conduct its own investigations(调查), Omi said.
Globalization means the scandal that started in China is a problem for people around the world, he said.
"Every country can be affected, so the international community should work together to solve the problem," he said.
Since the scandal over the contaminated dairy products broke, 6,244 infants have fallen ill, 150 have been diagnosed with acute kidney failure(肾衰竭), and four have died.
Investigations have shown the babies were made sick by the presence of melamine （三聚氰胺）in milk formula（配方奶粉）. Anothony Hazzard, a food safety specialist at the WHO's Western Pacific regional office, said the decision by some countries to recall milk products imported from China was "reasonable".
"I think many countries decided on the recall, I think under this kind of situation when the picture is not yet clear, it a very reasonable position that countries take."

The beat generation mainly referred to the youth who were born and brought up around the Second World War. They showed their ignorance of almost everything traditional, such as government authority ,respect for parents, one’s duty, moral standards, and traditional customs. They developed a kind of absolute individualism and liberty. They preferred long hair, mini dresses or close fitting clothes to show off the figure. They advocated （倡导）freedom of sex and cohabitation (同居).Their influence could be seen from the fact that about one third of the American couples living together were not married by law. And the divorce rate was very high. The endless U.S wars abroad and sharp class struggle at home caused many American youths to develop a kind of cynicism. They doubted the existing social system, possibility of harmonious human relations, and the long honored standard for correct behavior. They felt society overlooked their needs. Therefore, they refused to do any duty that was required of them by society. They declared “Don’t believe anyone over thirty.” All this came from the sick society. It’s wrong to imagine they all fought against capitalism in support of revolutionary things. Some of their ideas were even more decadent (颓废的)and impractical. It was an abnormal phenomenon in an abnormal society.?

generation practiced cohabitation?

Can you remember a morning when you’ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven’t slept well, your hair is a mess. Worse, you can’t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(无意识的,不自觉的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds.
The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup（打嗝）, that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!
