16．You're lost in the world of dreams and sleep．You roll over，smiling as you come across a swimming pool filled with chocolate．And then，your wonderful dream becomes a nightmare when someone is screaming，"Get up!"It's just what every teenager goes through each morning!
Now，there seems to be one school that finally understands that requiring teens to show up at 9am is not just cruel but also harmful to both the kids and the school．
The Monkseaton High School in North Tyneside，Britain，recently decided to experiment to see if there is any difference in student behavior if they just pushed back the start of their day by one hour，from 9am to 10am．And the results are surprising．
Since carrying out the later start，Monkseaton has seen a 28% drop in truancy，even hardly any lateness，and best of all，higher test scores．One of the reasons is that the teenagers are much happier to have the extra hour of sleep，but there is also a scientific reason behind why they need the extra sleep．
The school's decision to push back the time was based on the research done by Oxford Professor Russell Foster，who pointed out that teenagers and adults have different sleep cycles，explaining why teenagers go to bed late and wake up late．
While adults are wide awake and ready at 8am，teenagers are not fully awake until 10am，sometimes even noon．Teachers may argue that their students perform better in the morning，but in fact，it is because they are in the zone while their students are still sleepy，making the students easier to control．Memory tests prove that the more difficult classes should be in the afternoon when teenagers are most wide awake．
The Monkseaton school officials are encouraged by the results and plan on voting to make it a permanent change．

67．What's the best title of this passage？B
A．Get up early，teenagers!
B．Finally，a school understands teenagers．
C．Why do teenagers stay up late？
D．Difference between teens and adults．
68．What's the meaning of the underlined word"truancy"？C
A．grades     B．Subjects       C．Absence        D．classes
69．What can we learn from the passage？D
A．Teenagers and adults have the same sleep cycle．
B．Teenagers are fully awake at 10am．
C．Teenagers are much happier to sleep than study．
D．Teenagers need the extra sleep also for a scientific reason．
70．Which of the following statements is NOT true according to the passage？D
A．The Monkseaton school is satisfied with the result of experiments．
B．It is cruel for the teenagers to show up at 9am．
C．The Monkseaton school plans to change the school time forever．
D．Teenagers perform better in the morning than in the afternoon．

11．The Touchstone
    When the great library of Alexandria burned，the story goes，one book was saved．But it was not a valuable book； and so a poor man，who could read little，bought it for very little money．
The book wasn't very interesting，but between its pages there was something very interesting indeed．It was a thin strip of vellum on which was written the secret of the"Touchstone"!The touchstone was a small pebble that could turn any common metal into pure gold．
The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it．But the secret was this：The real stone would feel warm，while ordinary pebbles are cold．
So the man sold his few belongings，bought some simple supplies，camped on the seashore，and began testing pebbles．He knew that if he picked up ordinary pebbles and threw them down again because they were cold，he might pick up the same pebble hundreds of times．So，when he felt one that was cold，he threw it into the sea．He spent a whole day doing this but none of them was the touchstone．Yet he went on and on this way．Pick up a pebble．Cold-throw it into the sea．Pick up another．Throw it into the sea．Pick up another．Throw it into the sea．The days continued over a long period if time．
One day，however，about mid-afternoon，he picked up a pebble and it was warm．He threw it into the sea before he realized what he had done．He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away．
    So it is with opportunity．Unless we are cautious，it's easy to fail to recognize an opportunity when it is in hand and it's just as easy to throw it away．
59．The man bought the book because．A
A．he wanted to read it
B．it was very interesting
C．there was a secret in the book  
D．he wanted to find the touchstone
60．We can learn from the passage that the touchstone is．C
A．pure   B．cold C．magic    D．big
61．Why did the man throw the pebbles into the sea？A
A．Because he didn't want to get the same pebbles．
B．Because he didn't want others to pick them up．
C．Because he didn't like their ordinary looks．
D．Because he didn't like the cold feelings．
62．What does the author want to tell us in the passage？C
A．We about orate opportunities in our life．
B．We should seek for opportunities in the world．
C．We may seize opportunities when we are watchful
D．We may discover opportunities when forming habits．

15．Andy Steele lives just a few blocks from the campus of Black Hills State University in Spearfish，S．D．，so commuting（經(jīng)常往返） to class isn't the problem．But he doesn't like lectures much，isn't a morning person，and wants time during the day to restore motorcycles．
So Steele，a full-time senior business major，has been taking as many classes as he can from the South Dakota State system's online offerings．He gets better grades and learns more，he says，and insists he isn't missing out on the college experience．
"I still know a lot of people from my first two years living on campus，and I still meet a lot of people，"he says．But now，he sets his own schedule．
At least 2.3million people took some kind of online courses，according to a recent survey by the Sloan Consortium，an online education group，and two-thirds of colleges offering"face-to-face"courses also offer online ones．But what were once two different types of classes are looking more and more alike and often falling into the same pool of students．
At some schools，online courses originally intended for non-traditional students living far from campus have proved surprisingly popular with on-campus students．A recent study found 42percent of the students enrolled in its distance education courses were located on campus at the university that was hosting the online courses．
Numbers vary depending on the policies of particular colleges，but other schools also have students mixing and matching online and"face-to-face"credits．Motives range from lifestyle to adapting to a job schedule to getting into high-demand courses．
Washington State had about 325on-campus undergraduates taking one or more distance courses last year．As many as 9，000students took both distance and in-person classes at Arizona State last year．
"Business is really about providing choices to their customers，and that's really what we want to do，"said Sheila Aaker，extended services coordinator （協(xié)調(diào)人） at Black Hills State．
Many schools，such as Washington State and Arizona State，let departments and academic units decide who can take an online course．They say students with legitimate academic needs-a conflict with another class，a course they need to graduate that is full-often get permission，though they still must take some key classes in person．
21．What is the purpose of the passage？D
A．To introduce Steele to us，who prefers online courses．
B．To tell us about the development of campus courses．
C．To show the differences between campus courses and online courses．
D．To show more on-campus students are taking online courses．
22．We can learn from the passage that Andy SteeleC．
A．lives far from the campus   B．knows none of his classmates
C．wants to have his own lifestyleD．doesn't get good marks
23．Which of the following is NOT true according to the passage？B
A．The undergraduates attend the online courses for different purposes．
B．It is expected that distance education is popular with on-campus students．
C．About 325on-campus undergraduates took online courses in Washington last year．
D．Different colleges have different policies about online courses．
24．From what Sheila Aaker said in the passage，we can tellD．
A．business is the most popular major in universities
B．colleges should provide more majors for students
C．where the similarity between business and colleges lies
D．why colleges offer online courses to on-campus students．
