I am Sergey Brin! I was born in Moscow. In 1979,when I was 5, my family immigrated to California, USA . I remember that on my 9th birthday, I got my first computer “Commodore 64”.

Later I graduated with honors in the University of Maryland in Mathematics and IT. The main field of my science research was the technologies used to collect data from unsystematic sources as well as large quantities of texts and science data. I was the author of dozens of articles in leading American academic magazines.

The greatest event in my life happened when in 1998 I was preparing for the defense(論文答辯) of my Doctor’s degree in the Stanford University. There the fate made me meet Larry Page—a young computer genius. Larry belonged to the intellectual society. I and Larry quickly became friends when we were working together.

We were searching day and night on the Internet. We were finding a lot of information but with the feeling we still couldn’t find enough of what we were looking for . Naturally the idea for a search engine that would allow specific information to be found in the endless pool of data was born like it came to us. It wasn’t our plans but we gave up the education at the university. You know the next part ,maybe—we managed to turn an ordinary garage in Peplo Park, California , the USA into our first office, in which Google was born. With excitement we typed the name of the thing which we created with love on September 14th,1998—www.Google.com. Now after those years we bought this garage. As a symbol it will always remind us that everything is possible.

Which of the following would be the best title for this passage?

   A. The Birth of Google            B. The Founder of Google

   C. The Importance of Cooperation   D. The Great Contribution to the Internet

From the passage we know that Larry Page________.

A. was born from a rich merchant family        

B. was once a student in the Stanford University

C. published some academic articles when young

D. was Brin’s important partner in starting Google

Why did they found Google ?

A. Because they loved working with the Internet so much.

B. Because they wanted to make a lot of money through the Internet

C. Because they hoped to make it easy to find specific information online

D. Because they believed everything is possible.  

Which is the right order of what happened ?

   a. My family moved from Russia to the USA

   b. I met Larry Page

   c. I was given a computer as a present on my 9th birthday.

   d. google was born in an ordinary garage in California.

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(壽命) can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.

What does “these two killers” in the second paragraph refer to ?

A. Gene technology and another treatment of the two diseases.

B. The two murderers who killed the cloned baby

C. The two diseases of cancer and heart disease

D. Hereditary diseases and cancer

What’s the main idea of the third paragraph?

A.  How gene technology can be applied in the field of treating hereditary diseases.

B.  Gene technology can be used to clone human babies.

C.  Gene technology can help people to give birth of a baby.

D.  Gene technology can help the English imperial family out

In what way gene technology can help to treat hereditary diseases?

A. Using gene technology, people with hereditary diseases can have more living days.

B. Using gene technology, scientist finds the wrong gene and corrects it.

C. Using gene technology, human babies can be cloned.

D. Doctors can cure cancer and heart disease with the help of gene technology.

What is the main purpose of writing this passage?

A. Expressing the writer’s idea that gene technology will benefit people

B. Telling people the advantages of gene technology

C. Telling the readers that gene technology will not benefit people

D. Explaining that gene technology will also do harm to the humanity
