【題目】下圖是“南水北調(diào)中線干線工程路線示意圖”，在輸水工程中，輸水道采用明渠和暗渠兩種方式，明渠輸水采用與沿線河流立交方式，不與地表水發(fā)生水體交換，暗渠則采用地下涵管輸水方式。完成下面小題。

【1】在南水北調(diào)中線工程中，明渠、暗渠輸水道如此設(shè)計(jì)主要目的是（ ）

A. 避免水分蒸發(fā)B. 節(jié)約耕地資源

C. 確保水質(zhì)良好D. 保障水量供應(yīng)

【2】圖中黃河以北部分地區(qū)將生產(chǎn)冬小麥的土地季節(jié)性休耕，種植雨熱同季的春玉米。該做法可以( )

A. 提高太陽(yáng)輻射利用率B. 緩解地下水緊張狀況

C. 增強(qiáng)農(nóng)作物抗旱能力D. 改善土壤肥力和性狀

【答案】

【1】C

【2】B

【解析】

【1】本題主要考查明渠、暗渠輸水道的主要目的。讀圖分析可知，南水北調(diào)的線路較長(zhǎng)沿線所經(jīng)地區(qū)經(jīng)濟(jì)發(fā)達(dá)，排污量較大，因此為了保護(hù)水質(zhì)，采用名曲和暗渠方式，故選C。

【2】黃河以北屬于溫帶季風(fēng)氣候，雨熱同期，年降水量較小，冬小麥在春季處于返青季節(jié)，需水量較大，引水灌溉會(huì)導(dǎo)致地下水位下降，從而產(chǎn)生地下漏斗等問(wèn)題，因此種植雨熱同季的春玉米，可以減少在旱季時(shí)水資源的用量，減少地下水緊張狀況，B正確。故選B。

【題目】(E)

The World Wide Web（www.萬(wàn)維網(wǎng)）turned 25 years old on March 12th. It has become a very important part in our daily lives. We can’t imagine living without the web, the short form of the World Wide Web.

In 1989, a British engineer named Tim Berners-Lee came up with the idea of the Web. It is a group of “pages” of information that are connected to each other around the world. That is the very beginning of the Web. Since then, the Web has greatly changed the way people live. With a click(點(diǎn)擊)of a mouse we can read news, buy things, make friends and learn anything we’re interested in.

Now, 25 years after its birth, how will the Web influence life in the future? Scientists believe there are both advantages and disadvantages. w W w .x K b 1.c o M

A growing Web will help build “better relationships” between different cultures. Also in the future, everyday items could be connected to the Web. We could share plenty of information to make our daily lives more convenient(方便的). So one day in the future, your front door could send you a message. “Dear sir, everyone has left the house, but I’ m still open!”

But scientists warn（警告）us that if we share personal information on the Internet it could get into the wrong hands.

“It’s not wise to spend a whole day in front of the screen. People need to get close to nature and enjoy the sun. Never be controlled by the Internet.” said Berners-Lee.

【1】How old is the World Wide Web?

【2】Who came up with the idea of the Web?

【3】What can we do by clicking a mouse according to the passage?

【4】Will the Web influence life in the future?

【5】What could happen if we share personal information on the Internet?

【題目】 Learning about the environment is very important. There are many good books that will help you learn. To get started, ask your teacher or a librarian for some suggestions. You can also look at some good websites with information about the environment and climate change. Climate change may be a big problem, but there are many little things we can do to make a difference.

Driving a car or using electricity is not wrong. We just have to be smart about it. Some people use less energy by carpooling . For example, four people can ride together in one car instead of driving four cars to work. Whenever we use electricity, we put greenhouse gases (氣體)into the air. By turning off lights, the television, and the computer when they aren't needed, you can help a lot.

Don't buy products that use too much energy. Some products, like certain cars, are made specially to save energy. These cars can travel longer on a smaller amount of gasoline. They don't pollute as much, either. Products like computers, TVs, and VCRs with the ENERGY STAR label (標(biāo)簽) are made to save energy. Buying products with these labels will help protect the environment. Buy recyclable products instead of non-recyclable ones. Recyclable products are usually made out of things that have already been used. It usually takes less energy to make recyclable products than to make new ones. So when you go shopping, look for the recycle mark on the package-three arrows that make a circle. The less energy we use, the better.

【1】The passage is mainly written for .

A. car producersB. school studentsC. parents

【2】The underlined word “carpooling” in Paragraph 2 most probably means .

A. sharing a carB. pulling a car C. selling a car

【3】From the passage, we can learn that .

A. turning off the electricity when it isn't needed can save a lot of energy

B. electricity will cause great trouble to our environment

C. cars using less energy will not put greenhouse gases into the air

【4】If you use recyclable products instead of new ones, you can spend .

A. more moneyB. less energyC. more energy

【5】Which of the following can be the writer's opinion?

A. No pains, no gains.

B. Rome was not built in one day.

C. Little things can make a big difference.
