Last Saturday on the way to the mall, two children, a boy and a girl, came running towards me with bottles on their hands, asking if I wanted bottled water. It was a surprising gesture. I was wondering if they were doing fund-raising. I knelt and asked them where their parents were and how much a bottle of water cost. Then two adult women came up to me explaining what the children were doing. “We are teaching the children to give without anything in return. We are teaching people to accept without giving in return. ”
Two mothers had bought bottled water and placed a sticker(小贴纸)on all bottles with five different quotes(引述):
1. Smile at everyone. You’ll never know when someone may need it.
2. If Plan A does not work, there are 25 more letters in the alphabets.
3. Have a thirst for life. Every day is filled with possibilities.
4. In your thirst for knowledge, be sure you don’t drown in all the information.
5. Dig your well before you’re thirsty.
The bottle I have has quoted No.5. A sudden change of attitude opened up between me, the mothers and the children. We are no longer strangers to each other. We were having such a great time chatting and I ended up helping them give away the rest of the bottled water.
One young lady was so thankful that she happily accepted the water and said it was the best thing that happened to her all day since she had a bad day at work. A man refused and walked away saying “no thanks”. A couple kept on bowing to us in gratitude. When it was all done, the children and I were giving each other high-five. It was so much fun. I think I had more fun doing this than the mothers and the children.How did the author feel when he was offered bottled water?

| C．Excited | D．Disappointed |
Different quotes were placed on the bottles to ________.
| A．inspire others to think positively. |
| B．show how rich and colorful our life is. |
| C．encourage people to get more bottled water. |
| D．explain why at times abandonment is necessary facing trouble. |
What did the author do after chatting with them?
| A．Buy the rest of the bottled water. |
| B．Give away some money for charity. |
| C．Decide to meet with them regularly. |
| D．Join them in being kind to strangers. |
What do we know from the last paragraph?
| A．Children had more fun from this than adults. |
| B．This random act of kindness is warmly welcomed. |
| C．People responded quite differently to this activity. |
| D．The author learned a lot from this random act of kindness. |

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
A. what stem cells were B. whether they would grow back
C. how long it would take to re-grow D. how they would re-grow
41. A newt will re-grow its leg if _____.
A. its ankle was cut off but the nerve bundle was good
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle were cut off
42. What do the underlined words “these materials” refer to?
A. Nerve bundles and proteins. B. Proteins similar to n-AG.
C. Stem cells and proteins. D. Stem cells and nerve bundles.
43. The first sentence of the passage _____.
A. acts as a lead–in B. shows where researchers got their new ideas
C. states the author’s opinion D. describes the result of researchers’ studies
三、阅读理解(共20小题;每小题2分，满分40分)
A
China news, Beijing, Feb. 9 --- Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.
Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.
The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people's average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?
At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.
36．According to the passage, what is the average housing price per square meter in China?
A．8000 yuan B．10000 yuan C．7000 yuan D．It's not mentioned here
37．Which of the following does NOT support the idea that the average housing price in China is even higher than in the United States?

environment and supporting facilities.
B．American people's average income is several dozen times higher than that of Chinese
people.
C．The houses in US are not sold in terms of building area, as most Chinese property
developers do when they sell their houses.
D．There are more people who need houses in China.
38．What is the main idea of this passage?
A．The housing price in China is so high that the government should do something useful to prevent it.
B．There are some bubbles in Chinese real estate market.
C．The average housing price in China is even higher than in the United States.
D．Chinese government issued a set of policies that aimed to benefit the public.
39．How many measures are mentioned in the last paragraph in order to reduce the high
housing prices?

You can love them or hate them, but no matter which tourist destination you visit, chances are you’ll see someone
with their head buried in a Lonely Planet guidebook.
Lonely Planet is one of the world’s largest travel guide brands, publishing more than 500 different guides in eight languages. The popular brand also produces television shows, websites and podcasts(播客)all devoted to travel.
Some people praise Lonely Planet books because they make traveling easy and affordable. They also save time and make sure you don’t miss the best things.
They also provide the reviews of hostels(旅店), hotels, restaurants and ticket information about your destination.
This can be great if you’re a nervous traveler, or if you haven’t traveled by yourself before. If you’re in a country where you don’t speak the language, sometimes there’s nothing better than getting into a taxi and opening up a guidebook. You simply point to a map that directs the taxi driver to a hostel that’s cheap and clean, with friendly staff and cold beer.
But others criticize Lonely Planet and other travel guide publishers like them. They say guidebooks take the fun and spontaneity(自发性)out of traveling, and that part of the enjoyment of travel comes from the fact that anything can happen. They also regret that if you follow a guidebook, you’ll end up doing the same thing and having the same experience as everyone else. You might end up seeing the same group of people over and over, because everyone is reading the same book and following the same route.
Another criticism of travel guides is that they have a large impact on local communities. For example, some locals devote their lives to behaving in ways that attract tourists. They pretend to live a traditional lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.
67. The Lonely Planet guidebook can bring you the following advantages EXCEPT that __________.
A. you can speak a foreign language when opening a guidebook
B. you can easily find a nice place to stay in a strange city
C. it provides lots of useful information about your destination
D. it can help you save time and money when traveling
68. People criticize the guidebook because __________.
A. it is not as useful as most travelers expect
B. tourist destinations will be crowded if everyone follows the same route
C. travelers may not get the chance to have unexpected adventures
D. local people keep modern lifestyles under its influence
69. What do we know about the Lonely Planet guidebook from the text?
A. It’s a world-famous brand only producing guidebooks for travelers.
B. It’s very useful to a person who’s nervous about touring an unfamiliar place.
C. It’s very useful to a tourist who likes to repeat others’ experiences.
D. It is loved by all travelers because of the convenience it brings to travelers.
70. Which of the following best shows the structure of the text? (①—⑦ stand for Paragraph 1
—Paragraph 7 )
A. ① B. ① C. ① D. ①

Live Earth Announces 2010 Global Event!
This is the web version of the October 15, 2009 Live Earth email to members. Click here to join and receive bi-weekly updates from Live Earth.
Live Earth is pleased to announce the largest worldwide water initia
tive(倡议)in history to help fight the global water crisis. The Dow Live Earth Run for Water—to take place on April 18, 2010—will consist of a series of 6 km run/walks (the average distance many women and children walk every day to get water) taking place over the course of 24 hours in countries around the world, featuring concerts and water education activities, raising awareness and funds to help solve the water crisis. Jessica Biel, Alexandra Cousteau, Pete Wentz, Angelique Kidjo and Jenny Fletcher will lend their names and their time in support of this global event.
Water shortage is a major issue affecting countries, communities and families all over the world. One in eight people doesn’t have access to safe, clean drinking water. Communities in Africa, Latin America and Asia suffer 1.8 million deaths every year from diarrheal(腹泻）diseases and the death of 5,000 children each day due to inadequate water infrastructure(基础设施). In these areas, women and children are forced to walk 6 km (3.7 miles) each day to get water that is likely unsuitable for drinking. However, the water crisis is not only limited to developing nations. Adding to these existing issues, the effects of climate change are increasingly impacting both supply and quality of available fresh water throughout the world.
In 60% of European cities with populations greater than 100,000, groundwater is being used faster than it can be replenished(补充). By 2025, two-thirds of the world’s population could be living under water-stressed conditions.
You can help solve the water crisis by participating in the April 18th event. Run/walk registration is now officially open! Sign up now at http://liveearth.org/run.

The New York Times, the Wall Street Journal, Financial Times and some other newspapers have published articles indicating that cyber attacks targeting Google and several other U.S. companies were from China. Such accusations are biased(有偏见的).
These articles take as evidence that hackers’ IP addresses could be traced back to two schools in China. However, it is common sense that hackers can attack by controlling computers from anywhere in the world. This fact also explains why hackers are hard to be tracked down.
Computers in China are easy to be controlled by hackers as the majority of Chinese Internet users lack security awareness and adequate protection measures.
The hackers’ IP addresses could by no means vindicate(证明正确)the newspapers’ accusations that the attacks were carried out by Chinese citizens or from within China.
The New York Times says one of the schools from which the cyber attacks were said to originate has military support. Another school “has received financing from a high-level government science and technology project.”
The New York Times went to great lengths to mention that “graduates of one of the school’s computer science department are employed by the local military each year.” The paper, however, did not care to tell its readers that a school in China does not need to have any special relationship with the military to have its graduates in uniform. It is also true in the United States, where the New York Times is based.
China’s attitude toward cyber attacks has been unequivocal and has adopted laws against such crimes, as China is one of the countries that suffer from cyber attacks.
The U.S. government, on the other hand, takes an uncertain attitude toward cyber attacks. According to media reports, the U.S. Homeland Security and Defense departments have both openly employed hackers.
People with a “blackhat perspective” and knowing how to “do threat modeling” are the best choices, said Philip Reitinger, Department of Homeland Security deputy undersecretary, at an information security conference last October.
Cyber crimes could cause immense losses to individuals, companies and nations. Effective supervision(监督) and closer international cooperation are ways to improve cyber security. Finger pointing is not.
