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4部分:阅读理解(第31——45题,每题3分,共45分)
下面有3篇短文,每篇短文后有5道题。请根据短文内容,为每题确定1个最佳选项。
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 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 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 th , 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 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 .

D the design of an auditorium
er operas and Mahler symphonies sound fuller in an auditorium with
A a short reverberation time

A achieve a pleasing mixture of sound
B get rid of all reflections
C not have absorbers.
D have smooth surfaces
e pillars and corners may
A make sound rich and full
B be cures for sound problems
