A senior official in charge of Internet security has claimed that the country has become the world' s biggest victim of cyber-attacks.
In an interview with Xinhua over the weekend, Zhou Yonglin, deputy chief of the operations department of China National Computer Network Emergency Response Technical Team ( CNCERT), also dismissed Google' s complaints that hackers traced to China had attacked its servers.
Google has not yet given CNCERT any report on the company' s complaints about the attacks, according to Zhou. "We have been hoping that Google will contact us so that we could have details on this issue and provide them help if necessary.”
Foreign firms such as eBay have turned to CNCERT for cyber security issues in the past year. Last year, the Internet security watchdog received 21,618 complaints from foreign companies, of which 1,095 cases were solved after combining similar cases. These cases included the trojan and phishing attacks (釣魚攻擊) against eBay /Paypal, JPMorgan Chase & Co and MarkMonitor Inc.
China has also sought other countries' help to clear web pages with malicious content. In November 2009, CNCERT reported to its US counterpart, the US-CERT, about two US-registered domain (域) names that were planting trojans on hundreds of Chinese websites. The domain names were shut down within two days of CNCERT’s requests.
With the number of Chinese netizens soaring but their Internet security awareness lagging, hackers have made China their primary target, Zhou said. He accused overseas hackers, especially those in the US, of illegally controlling computers in China by implanting malicious programs including trojans and zombie programs.
Compared with Interact security issues in the US, Japan and the Republic of Korea, it is very serious in China. Last year, 262,000 IP addresses in China were hit by trojans planted by nearly 165,000 overseas IP addresses. Those from the US ranked first, accounting for 16.61 percent.
60. What is the best title of the passage?
A. Google attacked by unknown hackers.                  
B. US legally responsible for Internet Security
C. Malicious Programs, an International Problem
D. China, the world' s biggest victim of cyber-attacks
61. Who does the underlined "a senior official" refer to?
A. An interviewer from Xinhua News Agency.
B. Deputy Chief of operation department of CNCERT.
C. A high official from Google Company.                 
D. A representative from foreign firms.
62. The author mentions eBay as an example of ________.
A. complaining for the cyber attacks                         B. seeking other countries for assistance
C. turning to CNCERT for cyber security                   D. taking USA as a counterpart
63. What does the writer intend to tell the readers in Paragraph 5?
A. The global cyber-attacks are mainly from the US.
B. International cooperation quickens steps to settle cyber issues.
C. The two US-registered domains are the counterparts of US-CERT.
D. CNCERT shut down the two US domain names within two days.

Though your parents probably meant to have your name last a lifetime, remember that when they picked it they’d hardly met you, and the hopes and dreams they cared for when they chose it may not match yours. If your name no longer seems to fit you, don’t lose heart. Film stars change their names, and with some determination, you can, too.
If you wish to pick up a new name, you don’t need to make the change official. Under common law, all that is necessary is to start using the name of your choice. Remember, though, that you must use it everywhere—even with your mother—for it to become your legal name.
Getting friends and fellow workers to call you Leach instead of Lola may be harder than any paperwork involved, but you’ll probably meet official resistance, too. Be sure that no law prevents you from using the name you have chosen, unless you use it for the purpose of cheating. If the gas company tells you that you cannot get your bill under a new name, they are wrong. You don’t have to show them any sort of court document. You have a right to be called by whatever name you choose.
By this time, you’ve probably realized that changing your name is more difficult than replacing your furniture or changing your hair color, though the effect can be unusually encouraging. Don’t care too much if you have to keep reminding others of your change of a new name—keep on, and your friends and lover will accept your new name. Good luck!
51.   You may wish to change your name because _____.
you are required to do so
you don’t mean to have your name last a lifetime
you like to follow what film stars often do
you may not like your parents’ choice
52.   If you wish to start using the name of your own choice, you _____.
must get friends to call your new name
don’t have to get permission from anybody
must use it with your mother first
need to be approved by the court
53.   No law keeps you from using whatever name you have chosen, if only ____.
you pick up a new name not for the purpose of wrong-doing
you can get your fellow workers to call you the new name
the gas company agrees to get your bill under your new name
some sort of court document is given to you
54.   You may realize that changing your name ____.
usually has good effect
is actually asking for trouble
is not as easy as rearranging your room
means you have to go through some trouble
55.   The purpose of the writer in writing this passage is to _____.
show you the need of changing your name
encourage you if you want to change your name
tell you how easy it is to change one’s name
list all the difficulties in changing one’s name

第一節(jié)  閱讀理解(共15小題,每小題2分,滿分30分)
閱讀下列三篇短文,從每題所給的四個選現(xiàn)(A、B、C和D)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
American like to visit the national parks. In 1996, over 250,000,000 people visited areas run by the National Park Service. Experts predict that by 2010, 500,000,000 people per year will visit the parks. As a result, people are trying to think of ways to protect the parks from the crowds.
The crowding of the parks has caused several problems. One is that there is not enough space for all of the people who want to use the parks. To cope with this problem, national parks may require reservations months in advance for some spots. The Park Service may also raise entrance fees at these places.
Another problem caused by increased park use is pollution. Some garbage and waste can be cleaned up, and the cleanup can be paid for by increased entrance fees. To cut down on noise pollution and air pollution, officials may decrease the number of cars allowed in parks. If this happens, people may use buses to travel around the parks. Officials may also limit the use of jet-skis, snowmobiles (摩托雪橇), motorboats, and sightseeing helicopters and planes.
The parks are also threatened by development that is going on around them. For example, around Yellow Stone Park, many motels (汽車旅館), golf courses, resorts, and other tourist attractions have been built. Some of these developments affect areas that are used by animals. People will have to learn to agree about ways to protect the parks. If they do not, there will soon be no reason to visit these national treasures.
1. By 2010, the number of visitors will rise by ______ per year.
A. 250 million              B. 500 million              C. 2.5 billion         D. 5 billion
2. If you want to visit the national parks, you may have to _____ in the future.
A. pay less than before                         B. stay there for months
C. book the ticket before months           D. fill in a form to apply for the ticket
3. Entrance fees may be increased _______.
A. just for the benefit of the National Park Service
B. either to limit the number of visitors or to pay for the cleaner
C. not only to protect the animals but to reduce the noise pollution
D. merely for the development of the national parks
4. What does the underlined sentence in the passage mean?
A. People are not supposed to visit the national parks for fear that they will harm the animals.
B. Only if more man-made tourist attractions are built will more people visit the parks.
C. It is reasonable to keep the balance between the development of the parks and the reserve.
D. People will not visit the national parks since there are no golf courses and resorts.
5. What can be inferred from the passage?
A. High fees may probably keep some people out of parks.
B. Helicopters and planes will not be used in parks any longer.
C. The bus will become the only toot in parks with the purpose of pollution reduction.
D. The National Park Service welcomes as many visitors as possible.

Some people think that all wild animals are dangerous. Actually, very few of them will attack a man if he leaves them alone. If you met a lion or an elephant, suppose, you would run away, but even a lion will keep away from a man unless it is very hungry. Lions and tigers only kill and eat men when they have grown too old and too weak to catch their usual food, such as deer and other small animals. If you saw a wild elephant, perhaps you would be frightened. Elephants usually run away at once unless you attack them. Some animals get very frightened if they only smell a man; some take no notice at all but quietly walk in another direction. Wild animals only attack hunters when they are afraid that the hunters mean to harm their young ones, or then the hunters shoot at them and make them angry.
60. The word attack is closest in meaning to ________.
A. hurt         B. catch             C. hit             D. follow
61. Lions and tigers will not kill or eat men ________.
A. unless men try to run away                 B. if they are too old and too weak
C. if they are able to get enough of their usual food  D. however men act towards them
62. Some animals run away when they smell a man probably because _________.
A. they dislike the smell               B. they think men are dangerous to them
C. they don't want to eat men           D. they want to eat weak men

A. how to protect wild animals              B. how animals look for their food
