試題分析：考查冠詞。本題第一空是固定搭配make a difference起作用，有影響；第二空中的success本來(lái)是一個(gè)抽象名詞，在本句中具體化成為一個(gè)可數(shù)名詞指一個(gè)成功的人或者一件成功的事情。句意：如果這個(gè)實(shí)驗(yàn)成為一個(gè)成功的實(shí)驗(yàn)，那么它會(huì)起很大的作用。故A正確。
考點(diǎn)：考查冠詞
點(diǎn)評(píng)：本題著重理解定冠詞和不定冠詞的區(qū)別，對(duì)于冠詞特指和泛指的考察是歷年來(lái)高考的必考點(diǎn)，平時(shí)的學(xué)習(xí)要多進(jìn)行積累，仔細(xì)分析特指還是泛指。同時(shí)，更為重要的是要多去積累習(xí)慣表達(dá)，特殊表達(dá)，這也是近幾年高考習(xí)慣考的地方。總而言之，多解題、多理解、多積累才是制勝的法寶。

In some countries in which there is very little rain at any time, the farmers have to irrigate their fields. Irrigation is easy enough if there is a great river near the crops, and if there is plenty of water in it. Canals carry the river water to the fields when necessary. In some seasons there may be too much water in the river, and the water may flood all the land near it. At other times the river water may not be enough for all the farmers, and then it will be difficult to irrigate the fields.
To prevent these difficulties, a dam may be built across the river. This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land. A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water. Most people will accept that and will be ready to move to other places. Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.
Dams have been built for centuries in different parts of the world. Modern dame are usually built of concrete（混凝土）but earth dams were used in India and Sri Lanka about 2500 years ago. There was another across the River Tigris very long ago, and large numbers of irrigation canals were made in Iraq to irrigate the land. The Romans were great dam-builders and there was also a famous dam at Ma’ rubin Arabia.
We cannot use sea water for irrigation; the salt will not allow the crops to grow. Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water. This is done in a few countries, but the fresh water is for drinking. There is not enough at present for irrigation. Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea.
【小題1】The first paragraph mainly talks about         .

A．the problems caused by river water
B．the necessity to irrigate the field
C．the water shortage in some countries
D．the canals carrying water to fields
【小題2】A dam is usually built         .
A．to cover the houses and fields
B．for people to have the right amount of water at all times
C．to grow crops better
D．to form a large lake
【小題3】The underlined word“that”means        .
A．a(chǎn) dam will be built across the river
B．a(chǎn) dam will store water for dry seasons
C．in wet seasons a dam will prevent the flooding of the land
D．houses and fields will be covered will water
【小題4】The third paragraph suggests that        .
A．modern dams are made of concrete
B．Romans once built many great dams
C．there was too much water in 1rap in the past
D．modern dams are better than early dams

For millions of Chinese Internet users, the penguin is more than a flightless bird from the Antarctic. To them it is the symbol of QQ, the instant-messaging service marking its 10th anniversary.

QQ’s creator, Ma Huateng, 38, is a lover of stargazing, and describes himself as a combination of idealist and realist. “ I’m introverted. My friends believed I was too shy to find a girlfriend,” Ma said. He found a girlfriend, now his wife, through chatting online on QQ. Born in Hainan province, Ma loved watching stars and dreamed of becoming an astronomer. He moved to Shenzhen, along with his parents, in southern Guangdong province when he was in his teens. Ma was impressed by the slogan “ Time is money, efficiency is life” found all over the city. It was the most famous slogan born in Shenzhen, representing China’s reform and opening. The pioneering city provided chances for Ma to watch burgeoning reforms. He saw people carry big bags of cash to buy stocks after China launched a capital market in Shenzhen and Shanghai in the late 1980s. When he graduated from Shenzhen University in 1993, Ma designed a stock exchange software system and sold it for 50,000 yuan ($ 7,3000). He then worked as an IT engineer for five years.

It was in 1998 that Ma realized Internet would transform China and the world, and launched his own company, Shenzhen Tencent Inc. A unit of Tencent, Tencent Holdings Ltd, went public on the main board of the Hong Kong Stock Exchange in 2004. “ China’s reform and opening provided me with a chance to grow the company,” Ma said. The country had only 3 million Internet users when QQ made its debut in 1999, but now China has around 300 million Internet users, Ma said. Hu Qiheng, chairwomen of the Internet Society of China(ISC), said reform and opening not only improved people’s living standards, but also gave them a chance to explore the outside world and a chance for the Internet to boom in the country.

It was in the late 1990s that China’s major Web portals mushroomed, including Sina, Sohu, 163, Tencent and Alibaba. That boom came to sa sudden halt when the internet bubble burst in 2000. “We were under great pressure when the Internet bubble burst. Things have only recovered since 2005,” Ma said. The IT sector was among the first batch of industries in China to experience zero-tariff treatment, meaning that the nation’s Internet sector had to face challenges from international peers.

QQ, with around 450 million users, provides services such as chatting, music, games and QQ currency-an indispensable currency in china’s virtual community. “ Chinese websites have survived the competition with foreign peers over the past ten years, but it will be the next ten years that decide Chinese Internet enterprises’ fate,” Ma said. Domestic enterprises have to compete with international companies on services, innovation and core technology, he said. One of Ma’s favorite films is March of the Penguins-a French documentary directed by Luc Jacquet. He said: “Penguin is a lovely animal to me. It is a combination of love, courage and adventurism.”

1.Which of the following is true about the founder of QQ?

A．Creating an IT company of his own had always been his dream since childhood.

B．He constantly moved from place to place when he was in his teens.

C．The instant-messaging service he created brought him not only money but also a family.

D．He worked for the Shenzhen Stock Exchange after graduation.

2.China’s reform and opening led to the following results EXCEPT_________.

A．a(chǎn) rise in the living standards of Chinese people

B．a(chǎn)n opportunity for IT companies to grow

C．potential industrial competition from other countries

D．a(chǎn) chance for people to invest in overseas stock market

3.Which of the following events did actually take place?

A．QQ suffered from a sudden decrease in  the number of users when the Internet bubble burst in 2000.

B．QQ heped China’s Internet take flight.

C．QQ was equipped with the most advanced technology in the world when it made its debut in 1999.

D．QQ went public on the main board of the Shenzhen Stock Exchange in the late 1980s.

4.What can be inferred from the passage?

A．Sina and Sohu will develop services like chatting, music and games in order to survive the future international competition.

B．For the sake of domestic enterprises, the tariff needs to be adjusted to a higher value.

C．Ma Huateng views penguin as a lovely animal because it processes the characteristics that he does not.

D．The 50,000 yuan Ma earned from selling the stock exchange software system might be a part of his initial investment in Tencent.
