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．

13．I've often wondered if I might do more good as a travel agent rather than as a psychologist．It seems that I have been more dramatically affected by certain kinds of travel experiences than I ever have．
My trip to Iceland is a fine example of that．The plan was to spend two days in a remote mountain hut in Iceland．I was working on a photographic book about winter in Iceland and needed to capture images of this amazing region of high mountain peaks，smoky volcanoes，and lakes with floating icebergs．
The moment after we arrived，the weather turned extreme making visibility impossible．It snowed so much and the wind blew so hard that we couldn't leave the tiny hut．To stay warm，we walked around in circles much of the day inside the tiny hut．We tried to call for help but the radio did not work．Day after day，we watched our supplies of food and fuel grow dangerously short．We got acute cabin fever （幽居病） and started going for walks and ski expeditions outside．Even when the weather finally broke，nobody came to get us even though it was three days beyond our scheduled pickup．By the time the rescue team came to pull us out，we had all given up hope．
From then on，the world looks different to me，as does my life．It would have taken me years of psychotherapy to get to the same point．
Almost everyone has a story to tell，and interestingly，most of these experiences were not altogether pleasant at the time．In fact，it appears that the most constructive life-changing journeys were those that involved some sorts of awful and uncomfortable events that forced the person to develop new resources，increase confidence，and solve problems in new ways．

A．enjoy the natural beautiful floating icebergs

A．were in despair before they were rescued
B．stayed in the hut for three days altogether
C．got sick because of going for ski outside
D．got rescued immediately the weather turned fine
24．Which of the following statements is true according to the passage？D
A．The writer is a travel agent who loves difficult challenges．
B．In Iceland the weather is always extreme and it snows a lot．
C．The travellers were so depressed that they needed psychotherapy．

15．Andy Steele lives just a few blocks from the campus of Black Hills State University in Spearfish，S．D．，so commuting（经常往返） 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 （协调人） 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．
