題目列表(包括答案和解析)

 The hole in the earth's protective ozone layer(臭氧層)won't repair itself until about two decades later than had been expected, scientists announced.

The ozone layer blocks more than 90 percent of the sun's ultraviolet radiation(紫外線輻射), helping to make life on Earth possible. For many dacades, ozone was depleted(削減) by chlorine and bromine gas in the air. A hole in the ozone layer formed over the Southern Hemisphere.

Computer models had forecast that the hole would fill back in by 2050. An improved computer model forecasts the recovery won't occur until 2068. The model, fed with fresh data from statellites and airplanes, was supported by the fact that it accurately reproduced ozone levels in the Antarctic stratosphere(平流層)over the past 27 years.

The ozone hole is actually more of a broad region with less ozone than ought to occur naturally. It is not limited to Antarctica, as is often believed.

Over areas that are farther from the poles like Africa or the US, the levels of ozone are only three to six percent below natural levels. Over Antarctica, ozone levels are 70 percent lower in the spring. This new method allows us to more accurately estimate(估計)ozone-depleting gases over Antarctica, and how they will decrease over time, reducing the ozone hole area.

Paul Newman, a scientist,said that the ozone hole has not started to become smaller as quickly as expected. They figure it will not become much smaller until 2018, after which time the recovery should proceed more quickly. And the hole will not be filled in again until 2065.

1.According to the passage, the ozone layer _______

A.absorbs as much as sunlight as possible

B.protects man against ultraviolet radiation

C.controls the changes in temperature

D.prevents the production of carbon dioxide

2.The improved computer model is believable because _________

A.it was once proved by facts

B.it has been studied for 27 years

C.it was created by many scientists

D.it is related to satellites and airplanes

3.The underlined word “they” in the fifth paragraph refers to ________

A.the levels of ozone

B.ozone-depleting gases

C.the ozone holes

D.the areas far from the poles

You Mi, a lovely and confident 17-year-old student, is the first Chinese high school student to appear on the cover of the popular young adults’ fashion magazine Seventeen.

“You is IN,” said Wang Lihua,Editor-in-Chief of Seventeen. “She is active and mature (成熟) because of her knowledge on everything from academic studies,to books on art,to movies. We find she’s the very style we’re looking for to represent young people’s attitudes.”

You also impressed Wang with her fluent English when they first met last year. As the hostess of an English broadcasting program at the High School Affiliated to Renmin University(人大附中), You is always praised for speaking English almost like a native speaker. “I’ve built up my English by watching thousands of English DVDs since I was 10,” she explained.

But for You,watching isn’t enough. Last year,while in Senior 1, she met a talented (有才能的) boy who showed self-made DV movies at the English Corner in her school.

“I thought it was so cool and I knew that I should start making my own films,” she said. So she wrote a campus (校園) story, persuaded schoolmates to star in it and then began shooting a 30-minute DV movie,all in English. “I played one of the leading roles,actually I was everything in my film. I worked on it every day during the holidays,” she recalled. The movie finally became a big hit on campus,earning You a strong reputation(名氣) as a DV movie director.

But this is not the only field she wants to master. Though a science student, You likes art, literature and fashion design very much.

“There are people who can be artists,there are people who edit books, and there are people who become film producers. But I just hope to mix all the things up!” she said. “There is an old saying I believe:Chances favor only the prepared mind.”

1.You Mi was chosen to be a cover of Seventeen, mainly because she _____.

A.is beautiful

B.she is lovely and full of confidence

C.is active and mature

D.has rich knowledge

2.You Mi’s fluent English is based on _____.

B.the influence of her parents

C.her deep interest in it

D.her making DV movie

3.The author mentioned a talented boy to show _____.

A.the great influence he had on You Mi

B.he was admired by his schoolmates

C.the young can do things as well as the adults do

D.DV movies are popular at school

4.In the 30-minute DV movie,You Mi didn’t act as a(n) _____.

A.director

B.musician

C.actress

D.film-maker

5.We can learn from the passage that _____.
