The Theory of Everything
If Stephen Hawking lives until the year 2017, he will have lived more than50 years longer than his doctors expected. When he was a college student,doctors discovered that he had a rare disease. This disease causes a gradual disintegration(分解)of the nerve cells in the brain cells that regulatevoluntary muscle activity. Death almost always occurs within two or threeyears.
Today Stephen Hawking cannot walk or speak. He cannot move his arms or hishead. He cannot taste or smell anything. And yet this man is Professor ofMathematics at Cambridge University, a position held by the famous scientistIsaac Newton in 1669.
Hawking is often described as the greatest scientist since Albert Einstein,but to the world outside science, he is also known as the man who madescientific theory understandable. His book, A Brief History of Time, has soldover eight million copies.
He says that since he does not have to think about his body or do any ofthe things other men have to worry about, such as washing the car or working inthe yard, he can dedicate all of his time to thinking. This puts him in theperfect position to find the answer to the question that he has dedicated hislife to. His question is: Is there a complete theory of the universe andeverything in it?
Despite his tremendous physical disabilities, he has already made some veryimportant discoveries about the origin of the universe, how the universe holdstogether, and how it will probably end. He has also been able to explain thesecrets of “black holes” in space. Now he is looking for a set ofrules that everything in our universe must obey. He calls it the Theory ofEverything. He thinks that someone will have found the answer within the next20 years.
If Stephen Hawking is able to find his Theory of Everything, he will havegiven the world the opportunity to understand things that will change the wholenature of science and probably also the way we live.

第一篇
Can you hear this?
When something creates a sound wave in a room or an auditorium (礼堂)listeners hear the sound wave directly from the source. They also hear the reflections as the sound bounces off the walls, floor, and ceiling . These are called the reflected wave or reverberant (反射的) sound, which can be heard even after the sound is no longer coming from the source .
The reverberation time of an auditorium is determined by thevolume or interior size of the auditorium .It is also determined by how well orhow poorly the walls, ceiling, floor, and contents of the room (including thepeople) absorb sound. There is no ideal reverberation time .The full-soundperformance of music such as Wagner operas or Mahler symphonies should have along reverberation time. The light, rapid musical passages of Bach or Mozartneed a reverberation time somewhere between.
Acoustic problems often are caused by poor auditorium design .Smooth , curved (弯曲的)reflectingsurfaces create large reflections . Parallel (平行的)walls reflect sound back andforth, creating a rapid ,repetitive pulsing(有节奏的跳动)effect. Large pillars (柱)andcorners can cause acoustic shadows as the sound waves try to pass around theobject . Some of these problems can be solved by using absorbers and relectorsto change the reverberation time of a room .For example , hanging largereflectors , called clouds , over the performers will allow some soundfrequencies to reflect and others to pass yo achieve a pleasing mixture ofsound.
1. This Passage is mainly about
A sound waves and their acoustic effect .
B the types of music orchestras play
C walls of an auditorium
D the design of an auditorium
2.Wagner operas and Mahler symphonies sound fuller in an auditorium with
A a short reverberation time
B a long reverberation time
C an intermediate reverberation time
D no reverberation time
3. Thispassage suggests that a good auditorium should
A achieve a pleasing mixture of sound
B get rid of all reflections
C not have absorbers.
D have smooth surfaces
4.Large pillars and corners may
A make sound rich and full
B be cures for sound problems
C be sources of sound problems
D function as well as clouds
5.The word “acoustic” in the last paragraph has something to do with
A performance B Music
C sound D noise

Outside-the-classroomLearning Makes a Big Difference
Puttinga bunch of college students in charge of a $300,000 Dance Marathon, fundraisersurely sounds a bit risky1.When you consider the fact that the money issupposed to be given to children in need of medical care, you might call theidea crazy.
Moststudent leaders don't want to spend a large amount of time on something theycare little about, said 22-year-old University of Florida student DarrenHeitner. He was the Dance Marathon's operations officer for two years.
YvonneFangmeyer, director of the student organization office at the University ofWisconsin, conducted a survey in February of students involved in campusorganizations2. She said the desire for friendship was the most frequentlycited reason for joining.
At largeuniversities like Fangmeyer's, which has more than 40,000 students, thestudents first of all want to find a way to "belong in their own corner ofcampus".
KatieRowley, a Wisconsin senior, confirms the survey's findings." I wanted tomake the campus feel smaller by joining an organization where I could not onlyget involved on campus but also find a group of friends."
All ofthis talk of friendship, however, does not mean that students aren't thinkingabout their resumes. "I think that a lot of people do join to 'fatten uptheir resume'", said Heitner."At the beginning of my college career,I joined a few of these organizations, hoping to get a start in my leadershiproles."
Butwithout passion student leaders can have a difficult time trying to weather thestorms that come. For example, in April, several student organizations atWisconsin teamed up3 for an event designed to educate students abouthomelessness and poverty. Student leaders had to face the problem of solvingdisagreements, moving the event because of rainy weather, and dealing with theuniversity's complicated bureaucracy.
"Outside-ofthe classroom learning really makes a big difference", Fangmeyer said.
1. Anextracurricular activity like raising a fund of $300,000 is risky because moststudent leaders_________.
A) arelazy
B) arestupid
C) arenot rich enough
D) will not take an interest in it
2.Atherican students join campus organizations mostly for_________.
A)making a difference
B)gaining experience
C) building friendship

3. Whois Katie Rowley? _________.
A) She'sa senior professor
B) She's a senior student
C) She'sa senior official
D) She'sa senior citizen
4. Whatdo student leaders need to carry an activity through to a successful end?_________.
A) Passion.
B)Money.
C) Power.

Covering the Coast All by Himself
University life is in no way cheap in Canada. It costs Peter Kemp, a computer science major at the British Columbia Institute of Technology in Vancouver, C$18,000 ayear.
Amazingly, the 21-year-old is covering the cost by himself.
For the past three years, Kemp has done a range of part-time jobs to pay for his tuition and living expenses. Last semester alone, he worked five jobs for 32-40hours a week. Life is busy, but Kemp enjoys it.
“Doing part-time jobs gives me economic independence,” said Kemp, who will begin his senior year this fall. “Having economic independence gives me the ability to take control of my life and make my own decisions,” said Kemp. “It has also helped me understand the value of money.
Among Kemp’s five jobs last semester, two were on campus. For one, he helped maintain the university’s computer labs. For the other, he worked at the IT service desk to help students and teachers solve their computer problems. He also worked for a small company that develops GPS systems. This job paid him well at C$27 an hours.
“These jobs made me put what I’ve learned in university to practical use,” Kemp said.“I accomplished creative and imaginative tasks by applying my abilities to the work. ”
Good time management skills help Kemp balance work and study. He’s a top student in his class. And he will be the student association chairman for his department beginning next semester. It’s a position that he has desired for a long time.“It will give me the opportunity to be the voice for my fellow students and make a difference,” says Kemp.
“I believe one of the key secrets to juggling(应付)everything is to avoid putting off tasks. This can leave you stressed and reduce the quality of your work and health,” he said.
“I often make a list of the things I need to do each day and rank them by their importance. The list helps me decide what task I should do first and when I should complete it. Remember to ask for help when you think you can’t finish something on time, or can’ t finish it by you
