Humans have observed and explored the oceans since ancient times.But it wasn’t until the 19th century that the scientific study of oceans began.The first major scientific expedition,and the one that firmly established the field of oceanography,was the around-the-world voyage of H.M.S.  Challenger.Setting out from England in 1872,the Challenger spent almost three and a half years gathering a wealth of information about seawater,sea life,and the ocean floor.Major oceanographic expeditions since then have included the South Atlantic voyage of the German ship Meteor in 1926 and the Deep-Sea Drilling Project from 1968 to 1983.Many individuals also have played important roles in advancing our understanding of oceans,beginning with Matthew Fontaine Maury in the mid-1800s;his work on oceanography and navigation led to a uniform system of weather reporting at sea.Since Maury’s time,oceanography has progressed rapidly.Early oceanographers had to contend themselves with tossing buckets overboard to see what they might haul in.Today’s oceanographers are equipped with space images,supercomputer models,and deep-sea robots that can crawl along the seafloor.As they set goals for the future,some oceanographers even dream of doing research in permanently manned stations on the bottom of the oceans.

Which of the following statements is true?

A.Humans didn’t explore the oceans until the 19th century.

B.Maury first established the field of oceanography.

C.Maury spent a lot of time in studying seawater,sea life,and the bottom of the ocean.

D.Many individuals also plays a very important part in advancing our understanding of oceans,such as Maury.

How many expeditions are mentioned in this passage?

A.Four.                       B.Three.                            C.Five.                       D.Two.

What can we infer from the passage?

A.The process of the oceanography has stopped at one time.

B.Maury’s work on oceanography contributes a lot to weather reporting at sea.

C.Nowadays the equipment for studying the oceans needs improving,because it is out of date.

Despite rising education levels, Americans of every age are reading less and less for pleasure these days, according to an analysis by the National Endowment for the Arts. The decline(下降) could have bad effects as people tune out books, tune in popular culture and become less socially engaged.
"We've got a public culture which is almost entirely commercial(商业化)and novelty - driven (追新)," says NEA chairman Dana Gioia. "I think it's letting the nation down."
The study gathers years of data on Americans' reading habits and finds that, at every age group, we're reading less.
Most of the data have appeared in private, government and university surveys, but today's report is the first to combine them into a single portrait. It suggests that the demands of school, work and family and the decisive advantage of other forms of entertainment have caused the decline in reading for millions of Americans.
·Only 38% of adults in 2006 said they had spent time reading a book for pleasure.
·65% of college freshmen in 2005 said they read little or nothing for pleasure.
·30% of 13 - year - olds in 2004 said they read for fun "almost every day," down from 35% in 1984.
According to Gioia, a poet, they decline is probably the single most important social issue in the United States today. The findings should be a wake - up call to educators to change the way they teach literature at every level. It was once believed that if someone went to college, they would become a lifelong reader. What we're seeing right now is that we're no longer producing readers. We're producing B. A. s and M. A. s and Ph. D. s.
Cioia also wants main media to wake up to how they can promote good books in many ways. He notes that when a character in the 1994 film Four Weddings and a Funeral recited a few lines of W. H. Auden's poem Funeral Blues, the poet briefly became a best seller.
65.The underlined phrase "tune out" in the first paragraph probably means________.
A.close    B.publish C.prove   D.read
66.According to Dana Gioia, the change of Americans' reading habit________.
A.is positive and valuable      B.does harm to the nation
C.is caused only by popular culture      D.can make poets best sellers
67.Which of the following is NOT the cause for the change in reading habit?
A.Demands of getting a B. A., M. A. or Ph. D.
B.Demands of family, school and work.
C.The change in the way the literature is taught.
D.Advantages of the entertainment.
68.We can infer that the number of teenagers reading for pleasure reduced by________in 20 years.
A.30%    B.38%    C.65%    D.5%

When I was growing up, 16 was always a magical age, a symbol of maturity, responsibility and of course more independence and freedom.  I sat through the hours of Driver’s Ed classes eager to get out on the road. I couldn’t wait to get my driver’s license.

But it’s a different story for today’s teens. In January, the U.S. Department Transportation released 2012 data that showed only 30.7 percent of U.S. teens got their license at age 16, Twenty years before, that number was almost 45 percent.

There are numbers of reasons for the fall – off. The growing responsibilities like paying for insurance and high gas prices discourage teens from getting behind the wheel. Plus, many teens today are so busy with homework, endless hours of activities and part-time jobs, that finding the time for Driver’s Ed classes may be more difficult that ever.

In addition, many states have raised the driving age, or restricted when teens can drive and who they can have in the car. Parents may also be making their own personal restrictions until they feel their teens are responsible enough to drive safely.

Driving is part of the American culture, but it’s not the central focus like it was 25 years ago. They have so many other things to do now. One of the more interesting factors delaying teens driving might be the change of their social life. Today, teens need to look no further than Face book or other social networking sites to connect with their friends. There is simply less need, maybe less desire, to be able to grab the keys and go.

Michelle Wei got her license as a senior in high school because her digital social life made it easy no to drive. “If I couldn’t get a ride to see my friend who lives a town over,” the 19-year-old said, “I could talk on IM or Skype.”

Research has shown that these online relationships can lead to higher quality friendships, so it isn’t necessarily a bad thing. However, it’s important to find a balance. If old face-to-face friendships are good, why not drive to find them?

1.We can infer from the first paragraph that         .

A.Driver’s Ed classes allowed teens to know what maturity was

B.getting a driving license at 16 was a must for American teens

C.16 was considered an age when one could get his driver’s license

D.teens could drive on the road without taking Driver’s Ed classes

2.What does the passage mainly talk about?

A.Desire to drive on the road declines among American teens.

B.Getting a license costs much more than ever before.

C.Social networking sites are changing the life of American teens.

D.American teens are becoming more responsible than ever.

3.Michelle’s Wei’s example is used to explain ________.

A.why American teens are crazy about digital social life

B.what social networking websites are bringing to American teens

C.to what degree the Internet is affecting the American car culture

D.what the Internet does to help teens to get a driving license

4.The last paragraph is reminding the readers that        .

A.the Internet h as a bad effect on the teen’s social life

B.teens should keep a balance in choosing their lifestyle

C.actual contacts can be replaced by talking on line

D.face-to-face friendship is always the best choice
