A: Recently, the word "clone" has appeared very often in the newspapers. Do you know its meaning?
B: Not exactly. I read a report in yesterday"s newspaper. It said a Scottish scientist had successfully cloned
a lamb named Dolly. It was the first time that a cloned lamb had been made from an adult sheep.
A: Actually, the word "clone" means to produce the "same" animal by taking cells (细胞) from an adult one.
I think, if we know how to do cloning, we need only keep a small number of sheep, cows and horses.
B: (A) It"s said that recently there have been some people who ever wanted to clone humans.
A: It seems interesting. (B)但你觉得那样做可能吗?
B: No, I don"t think so. First, I think we can"t clone a dead person because the cells in his body have been
dead already.
A: Then can we clone a living person?
B: Again no. You might clone yourself one after another, but it is only a copy, not a real you. It is only
something, not a human.
A: Well, you mean that a real human can speak, think and create, and these abilities(能力) can"t be cloned?
B: That"s right! I think the main purpose of Dr. Ian Wilmut, the "father" of Dolly, is to make better animals,
and it has nothing to do with human cloning.

A new school term begins. Is anything new at your school? Sichuan students are getting an extra (额外的) hour to sleep in the morning.
This year, Sichuan schools decided that students should start classes later. This should help them feel less
tired, For Junior high schools, the first classes will begin no earlier than 8:30 am.
The changes have made students happy.
Liu Xian, 15, said his class was excited by the news on the first day of school.
"It"s so good we can get up later!" said Liu.
Liu studies in Chengdu No.4 Middle School. He used to get up at 6:40 am. Now he can get up at 7:40 am
because class doesn"t start until 8:40 am.
Wu Hongli, 15, said the new timetable is good for her health. "I used to drink coffee every night or I would
feel too sleepy to finish my homework, "said Wu. "Now I can finish it without coffee." She used to get up at 6:30
am. Now she can get up at 7:30 am.
Wu Hongli"s mother was happy, too. She thought more sleep would help her daughter grow taller.
But some parents worried that more sleep would mean less learning. There used to be five classes in the
morning. Now there are only four.
Many teachers, though, say the changes will help students learn better.
"Students used to doze (瞌睡) for the first two classes in the morning," said Wu Zongping, an English
teacher at Chengdu No.12 Middle School. "But now they look fine and they learn much better than before." |

rays produce yellow, blue and green produce cyan, red and blue produce magenta. Red, green and blue mix to
create white (light). This colour model is used in computer monitors, television sets and theater.
