After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll （死亡人数） could have been much worse．More than 60 people died in this earthquake．By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25,000 victims．
Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a．m．on a holiday, when traffic was light on the city's highways．In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes．
Despite the good news, civil engineers aren't resting on their successes．Pinned to their drawing boards are blueprints （蓝图） for improved quake-resistant buildings．The new designs should offer even greater security to cities where earthquakes often take place．
In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood that bend without breaking．Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations．The most recent designs give buildings brains as well as concrete and steel supports．Called smart buildings, the structures respond like living organisms to an earthquake's vibrations．When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction．
The new smart structures could be very expensive to build．However, they would save many lives and would be less likely to be damaged during earthquakes．
1.One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that __________．
A．new computers had been installed in the buildings
B．it occurred in the residential areas rather．than on the highways
C．large numbers of Los Angeles residents had gone for a holiday
D．improvements had been made in the construction of buildings and highways
2.The smart buildings discussed in the passage __________．
A．would cause serious financial problems
B．would be worthwhile though costly
C．would increase the complexity of architectural design
D．can reduce the ground vibrations caused by earthquakes
3.It can be inferred from the passage that in minimizing the damage caused by earthquakes attention should be focused on __________．
A．the increasing use of robber and steel in capital construction
B．the development of flexible building materials
C．the reduction of the impact of ground vibrations
D．early forecasts of earthquakes
4.The author's main purpose in writing the passage is to __________．
A．compare the consequences of the earthquakes that occurred in the U．S．
B．encourage civil engineers to make more extensive use of computers
C．outline the history of the development of quake-resistant building materials
D．report new developments in constructing quake- resistant buildings

Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
1.What is the passage mainly about?
A. NPCs are beneficial in treating human diseases.
B. Chinese scientists succeeded in making NPCs from human urine.
C. Chinese scientists have found cures for all diseases.
D. A new technique was used to study the use of human urine
2.Pei and his tean try their best to work hard in order to________.
A. make more contributions to medical study
B. discover another new technique
C. make the technique more perfect
D. treat more patients suffering from bad diseases
3.What is the challenge of making NPCs in the previous method?
A. The ethical comcerns and immune system refusal
B. The difificulties in getting cells from human.
C. The under-developed techniques in medical science.
D. The lack of financial support from the government.
4.From the last paragraph we can infer________.
A. the new technique will be developed in science
B. the results and methods will be applied to treating cancers
C. the study will give a major push to the stem cell field
D. the mew technique will bring great profis

People in the United States have many ways to get news, some of which are available 24 hours a day. In a recent survey（调查）, about 15 percent of American interviewees said that they spend less than one-half to two hours per day watching, listening to, or reading the news. News comes from every source, not only from printed ways, but from TV, radio, and the Internet as well.
With the increased availability of news, serious questions have been raised about the role of the news media in society. Should the media report every detail about every story, even when the information does not seem timely or valuable? Some researchers are concerned that by focusing on everything at once, the media increasingly ignore the more important social, political and economic problems that we face. We cannot concentrate on what’s important by reading about what is not. One extreme example of this is the type of information covered by the tabloid（小报）media, which focus on negative stories of violence and crime.
How can people deal with all the news that is available to them? Some become “news resisters” and choose to turn their backs on news, resisting their desire to turn on the TV and read the paper every day. They argue that although daily news reports may provide us with many facts, they do not include the background or some information that we need to understand news events. They suggest that, instead of daily reports, we look for information that has more in-depth analysis of the news, such as monthly magazines.
1.What percentage of the interviewees spend less than one half to two hours per day paying attention to the news? (within 3 words)
2.According to the researchers, what is the disadvantage of news media? (within 6 words)
3.How do you describe tabloid media? (within 5 words)
4.Who are “news resisters”? (within 9 words)

Animals are not always animals. Some of them will try to cheat or cow some others in the way the human beings often do. Here is a fairy tale from Aesop for you to enjoy.
An eagle（鹰）made her nest at the top of a high tree while a cat, having found a convenient hole, moved into the middle of the trunk, and at the same time a wild pig, with her young took shelter in a hollow at its foot. The cat then decided to make all serve her in her wise way.
To carry out her design, she climbed to the nest of the eagle, saying, "Destruction is preparing for you and for me too, unfortunately. The wild pig, whom you see daily digging up the earth, wishes to uproot the tree, so she may on its fall seize our families as food for her young."

Having filled these fears into the pig, she went and pretended to hide herself in the hollow of the tree. When night came she went out silently and obtained food for herself and her children, but pretending to be afraid, she kept a lookout all through the day. Meanwhile, the eagle, full of fear of the pig, sat still on the branches, and the pig, terrified by the eagle, did not dare to go out from her cave.
