The scientist's knowledge must be exact.There is no room for half right or right just half the time.He must be as nearly right as the conditions permit.What works under one set of conditions at one time must work under the same conditions at other times.If the conditions are different,any changes the scientist observes in a demonstration must be explained by the changes in the conditions.This is one reason that investigations are important in science.Albert Einstein,who developed the theory of relativity,arrived at this theory through mathematics.The accuracy of this mathematics was later tested through investigations,Einstein's ideas were shown to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.

For many years, doctors have been studying the way the brain works. We all know that the brain has two sides, the left and the right. The right side controls the senses (seeing, hearing, feeling, tasting and smelling), and is the creative and imaginative side. The left side of the brain controls our logical thinking. It processes the information which comes in, and puts it into order, We call the left side the "educated" side of the brain and generally, in western societies, people have developed this side of the brain more than the fight side.
Scientists believe that our brain will work much more efficiently if both the right side and the left side are developed equally. In many schools today, teachers try to educate the children in such a way that both sides of the brain are used. This can be done with logical subjects including mathematics and science as well as with creative subjects such as art and literature. The result achieved by students who are educated in this way is usually better than the result of students who are educated in a more traditional way. Traditional teaching tends to exercise the left side of the brain without paying very much attention to the development of the right side.
great thinkers such as Bertand Russell the Philosopher, and Albert Einstein, the scientist, only in their work, but also in creative and imaginative activities. It was because of their many different interests in life that they were able to achieve the full development of both sides of their brain.
As long as Einstein and Russell lived, their brains functioned efficiently. It was their bodies, finally, which could not go on any longer.
The body improves ______.
A．with age
B．with use
C．with memory
D．with development
Nowadays, especially in China, everything seems to favor social intercourse (社交), such as gatherings of friends, KTV, group travel, dining tighter, playing cards and Mahjong, plus the Chinese-style. “street-crossing group.” Back home, discussions can still be boisterously carried on within the “circle of friends” of WeChat.
However, these scenes cannot always ease a sense of loneliness. Zhu Ziqing, a well-known professor of Tsinghua University, signed with emotion: “My loneliness increases as scene becomes much busier.” One popular song today is also called “A lonely man in crowds.” Actually, engaging in social intercourse requires ability, while being alone involves the whole character. These days, it is not easy to calm down totally and return to one’s true self. Willpower, intellect and discipline are required. Einstein said: “It is not your working time but your spare time that determines the possibility of whether you will be successful or not.” The “spare time” he referred to could be taken as “spending time by yourself.”
Lonely life could be either dull, boring and tasteless or abundant, interesting and colorful, depending on one’s quality, ambition and inspiration.
Just as the body constantly requires energy, the mind and soul also demand never stopping inputs. However, information, processed and integrated (融入) into knowledge, thoughts and feelings, instead of bustle (忙碌) seems to be the right condition. Successful careers in all walks of life worldwide have proved that “the soul grows in peace and talent is nurtured in loneliness”. In a sense, it may be reasonable to say that “Happiness tends to be shallow while loneliness involves depth”.
Man, in fact, needs loneliness more than happy time, and only abundant loneliness can produce quality happiness.

What can we infer from the second paragraphA.Being alone marks people depressed.

C.One may feel lonely even when surrounded by people.
D.We should attend social intercourse to decrease our loneliness.
What can we know from Einstein’s wordsA.You should be successful if you spend all your time by yourself.
B.You should exercise more if you want to keep your minds healthy.
C.You will not become successful if you join in more social intercourse.
D.You will be more successful if you can make your lonely time meaningful.
