根据以下资料,回答106-110题。
据初步统计,2008年我国全年水资源总量25567亿立方米,比上年减少8.9%,比常年减少7.7%;人均水资源量1945立方米,比上年减少9.3%;全年平均降水量615.5毫米,较上年减少4.5%,比常年减少4.2%。年末全国465座大型水库蓄水总量2109亿立方米,比年初减少 128亿立方米。
全年总供水量5716亿立方米,其中地表水源占81.4%,地下水源占18.2%,其它水源占0.4%。全年总用水量5716亿立方米,比上年增加83亿立方米,其中,居民生活用水 472亿立方米,生产用水5150亿立方米,生态与环境用水94亿立方米。与上年比较,生活用水增加2.2%,生产用水增加1.4%,生态与环境用水增加1.0%。在生产用水中,第一产业用水3720亿立方米,第二产业用水1335亿立方米,第三产业用水95亿立方米。全国人均用水量为435立方米,比上年略有增长。万元GDP(当年价)用水量273立方米,按可比价计算比上年减少8.3%;万元工业增加值(当年价)用水量144立方米,按可比价计算比上年减少9.8%。

下列说法中,正确的一项是( )。

A.2007年全年平均降水量比常年平均降水量高出3%

B.2008年全年总供水量中,地下水源比其他水源多1017亿立方米

C.每年生产用水占总用水量的比例超过九成

D.2008年全国人均每月生活用水量大约为36立方米

答案

参考答案:B

解析: 2007年全年平均降水量为615.5÷(1-4.5%)毫米,常年平均降水量为615.5÷(1-4.2%)毫米,则全年平均降水量比常年平均降水量高出[615.5÷(1-4.5%)÷[615.5÷(1-4.2%)]-1=(1-4.2%)÷(1-4.5%)-1≈0.3%,A项错。 2008年全年总供水量中,地下水源比其他水源多5716×(18.2%-0.4%)=1017亿立方米,B项正确。 2008年生产用水占总用水量的比例为5150÷5716=90.1%,从上题的分析可知2007年该比例也大于90%,但不能确定每一年的比例都大于90%,C项无法确定。 按人均用水量计算,2008年全国人均每月用水量大约为472÷(5716÷435)÷12=3立方米,D项错误。

     Ed Viesturs grew up in Rockford, Illinois, where the tallest thing on the horizon was the water tower.

But on Thursday, Viesturs became the only American to climb to the top of the world's 14 highest mountains.

     His last hike was up Mount Annapurna, in Asia's snowcapped Himalayas. At 26,545 feet, its peak is the

10th highest in the world. It is the mountain that inspired him to start climbing.

     "It tends to be the trickiest, the most dangerous," said Viesturs. "There's no simple way to climb it. There

are threatening avalanches (雪崩) and ice falls that protect the mountain."

     In high school, Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna. Herzog's

story was of frostbite (冻伤) and difficulty and near-death experiences. Viesturs was hooked right away.

     Viesturs got his start on Washington's Mount Rainier in 1977, guiding hikes in the summer. Fifteen years

ago, he set out to walk up to the world's highest peaks. Finally, he's done.

     The pioneering climber talks about mountains as if they were living creatures that should be treated with

respect. "You have to use all of your senses, all of your abilities to see if the mountain will let you climb it,"

said Viesturs. "If we have the patience and the respect, and if we're here at the right time, under the right

circumstances, they allow us to go up, and allow us to come down."

     What's next for a man who can't stop climbing? "I'm going to hug my wife and kids and kind of kick back

and enjoy the summer," says Viesturs. But for a man who's climbed the world's 14 tallest mountains, he will

probably soon set off on yet another adventure.

1. What record has Ed Viesturs set? [ ]

A. He has succeeded in climbing to the world's 14th highest mountain.

B. He has been to the top of the world's 14 highest mountains.

C. He has become the first to climb to the height of 26,545feet.

D. He has become the first man to climb to the top of 14 highest mountains in the world.

2. The underlined word "hooked" in Paragraph 4 can be replaced by "_____". [ ]

A. frightened

B. discouraged

C. interested

D. upset

3. The author used Viestures' words in Paragraph 6 to support a view that _____. [ ]

A. mountain climbing is a dangerous sport

B. mountains should be regarded as living creatures

C. mountain climbing needs more skills than physical energy

D. those who like mountain climbing won't stop climbing

4. What's the next probably plan of Viestures? [ ]

A. Stopping climbing and staying with his family.

B. Climbing to the top of the world's 14 tallest mountains again.

C. Climbing another one of the highest mountains.

D. Writing down the experiences about his adventure.
