In 1997, Dolly the sheep was the first mammal to be cloned from a single cell. Since then scientists have been working to explore more possibilities in the cloning world. Recently Chinese scientists have also successfully cloned mammals such as an ox.

Cloning is making a genetic copy of something else. This might be copying just one cell, or it could be a whole animal. The biggest star of the cloning world is a sheep named Dolly. She is a copy of her mother. This means that she is the twin sister of her mother who was six years older and she did not have a father!

Our bodies are made up of cells, which hold information contained in DNA. Organisms(生物体) get their DNA from the mum and half from their dad.

We all grow from a single cell, which contains these two parts of DNA. It is called the egg cell. It divides millions of times to give rise to the millions of cells, which form our body.

Each cell has a copy of all the genetic information needed by the body. This means that each cell of our body has enough information to create other human beings like us. All we need is an egg cell.

In the process of cloning, the scientists take out the DNA from an animal cell and put it into an egg cell taken from another animal. Before implanting it, the DNA of the recipient(受体) cell is removed.

This is how Dolly’s life began-from a single cell taken from her mother. The DNA in her mother’s cell was taken out and put into the egg cell of another sheep. Five months later, Dolly was born.

68What is the best title for the passage?

A. A Sheep Named Dolly   B. DNA   C. How do We Grow Up? D. What is Cloning?

69Which one is necessary to cloning?

A. An egg cell.     B. Man’s DNA.    C. Two cells from an animal.    D.A sheep.

70What does the underlined word “It” mean in Paragraph 4?

A. Two parts of the DNA.    B. Our body   .C. The egg cell.     D. Dolly, the sheep.

71Which is the correct order?

a. remove the DNA from the recipient animal

b. take out the DNA from an animal cell

c. implant the egg cell into the recipient animal

d. put the DNA into an egg cell taken from another animal

A. a-b-c-d B. b-d-a-c C. a-c-d-b  D. b-c-a-d

 C

The word “death” is a word many Chinese friends tell me I should not say aloud. They advise me to avoid the word because only speaking of it may bring ill fortune. I deeply believe, however, that to know how to live, we must also know how to die. The problem is how do we talk about death?   

   Like everyone in Taiwan this week, I have had “Tomb Sweeping Day”. I am proud to be part of a people whose culture sends millions of families to cemeteries on this special day to share memories and endless love.

   Today, eight days after the death of Pope John Paul II, millions of people of all backgrounds still grieve(悲痛) his passing away. He was a deeply human person who knew how to laugh and show emotions, a writer with a gift for words a leader who appealed to us by the sheer light of his love for life.

   On the same day and only hours before the Holy Father left us, a friend of mine named Veronica McBride died of cancer in a small Wisconsin city. My friend Veronica was 52 years old. She was an attractive, humorous young woman who, as the saying goes, “never married”. She published several humor books with her mother, Mary McBride. She enjoyed traveling, and for years sent Christmas card photos of herself standing beside monuments or odd animals. She fought cancer for five years. She joked about her treatment keeping her pretty because it kept her thin, and told me she didn’t mind losing her hair because of chemo therapy. “I get to wear nice wigs!”

   The last time I saw Veronica was when I visited her family on a sunny day in August in 2003. When she burst into the front door later and saw me in the living room, she ignored me completely in her hurry to hug her newest baby nephew, leaving me shaking my head in laughter at her.

   As we look to the significance of the Holy Father and his life, surely we must also keep our eyes open to see the wonder and goodness in ordinary people who show us how to live and how to die.

64. The purpose of the article is ___________.

  A. to memorize his friend Veronica    B. to talk about the significance of life and death

  C. to teach us how to face life and death  D. to compare his friend and the Holy Father Pope John Paul II

65. The underlined phrase “chemo therapy” in Paragraph 4 probably means ______.

  A. a medical treatment   B. a kind of cancer   C. a kind of medicine   D. the newest machine

66. Why does the writer compare the Holly Father with his friend?

  A. Because they are both the persons he admires.  B. Because they have a lot in common.

  C. Because he wants to show that ordinary people can be great as well.

  D. Because he wants to memorize them both.

67. From the phrase “burst into”, we can see that Veronica is ____________.

 A. brave    B. sportive     C. humorous     D. energetic

A

The newspaper seller was a clean, neat man, of about forty with a rather serious, unsmiling face. He didn’t speak much to the customers or to his helpers, but when he did he spoke slowly and quietly, as if to himself. He believed in efficiency, not conversation. and this was how the office workers, rushing to catch their trains, preferred it.

     It had been a good day. Lunch-time had been warm and sunny, and many people had bought magazines to read outside with their sandwiches. Now it was cold rainy, and people wanted an evening paper for a cheerless joyless journey ahead and a dull evening indoors.

     At 6:30, with the main rush over, he started to collect the money together and count it. Then he left the stand and went home. It was the assistant’s turn this evening to look after it till eight o’clock, when it would be packed away for the night. His large white Mercedes was in the private car park of a large government building. He’d parked there for six months, pretending to be part of a heating firm working in the building. They would find out about him soon, and he’d have to park in a garage again, which was annoying. Their charges were far too high. A couple of junior clerks, regular customers, happened to see him getting into his car. “must be a lot of money in papers, eh?” one of them shouted. He just smiled coldly in reply, and got into the car, placing the bags of money on the floor.

     He thought about the clerks on the way home. Like the majority of his customers, despite their white shirts and dark suits, they probably made in a week as much as he could make in a good day.

56.It seems unlikely that the newspaper seller would be the sort of man who would ______.

    A.be a cheerful companion         B.try to cheat a customer

    C.earn a great deal of money        D.trust his assistant much

57.The assistant’s job that evening was to ______.

    A.sell papers until 8 o’clock          B.start selling magazines at 8 o’clock

    C. count the money taken that day      D.lock up the car park

58.If they realized that he was not a heating engineer he would have to _______.

     A.park his car in a government car park  B.look for another free parking place

     C.pay to park his car in a garage     D.pretend he was a government employee

59.When the newspaper seller thought about the two clerks he decided they were _______

     A.badly dressed         B. very well off 

C.not as rich as himself    D. not as hardworking as himself
