than we realize. It is said that we share 40 percent of our genetic (遗传的) structure with the simple worm.
But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder
of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human
genome (染色体组).
To help them do this, they turned to the worm. The nematode (线虫类的) worm is one of the earliest
creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life
digging holes through sand. But it still has lots to say about human life, and what can be done to make it
better.
What the worm told Sir John and his colleagues was that each of the cells in the human body is
programmed like a computer. They grow, develop and die according to a set of instructions that are coded
in our genetic make-up.
Many of the diseases that humans suffer from happen when these instructions go wrong or are not
obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and
diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John
was the first scientist to prove the existence of programmed cell death.

B. They are not seen from the outside.

words. One example is the word " mouse". A computer mouse is not a small animal that lives in buildings
and open fields. It is a small device (装置) that you move around on a flat surface in front of a computer.
The mouse moves the cursor (光标) on the computer screen.
Computer expert Douglas Engelbart developed the idea for the mouse in the early nineteen-sixties. The
first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because
it had a tail at one end. The tail was the wire that connected it to the computer.
Using a computer takes some training. People who are experts are sometimes called hackers. A hacker
is usually a person who writes software programs in a special computer language. But the word" hacker"
is also used to describe a person who tries to steal information from computer systems.
Another well known computer word is Google. It is the name of a popular search engine for the Internet.
People use the search engine to find information about almost any subject on the Internet. The people who
started the company named it Google because in mathematics, googol, spelled g-o-o-g-o-l,is an extremely
large number. It is the number one followed by one hundred zeros.
When you "Google" a subject, you can get a large amount of information about it. Some people like to
Google their friends or themselves to see how many times their name appears on the Internet.
If you Google someone, you might find that persons name on a blog. A blog is the shortened name for
a Web log. A blog is a personal Web page. It may contain stories, comments, pictures and links to other
websites. Some people add information to their blogs every day. People who have blogs are called bloggers.
B. The first mouse was made from wood.
C. How the first computer mouse was invented.
D. Why the mouse has a tail.
B. he is skilled at computer technology
C. he always loads the newest softwares
D. he always stays at home developing softwares
B. is a company"s Web page
C. is linked to all search engines
D. usually contains information about personal experiences
B. It can help people communicate with each other.
C. It is used to do mathematical analysis.
D. It is the largest number in mathematics.
B. Acting: repetition of fixed words and movements
C. Teaching: a student-centered creative process
D. Similarities between teaching and acting
E. ( = AB) Differences between teaching and acting
F. ( = AC) A good teacher, not necessarily a good actor
1 To be a good teacher, you need some of the gifts of a good actor: you must be able to hold the
attention and interest of your audience; you must be a clear speaker, with a good, strong, pleasing voice
which is fully under your control; and you must be a- ble to act what you are teaching, In order to make
its meaning clear.
2 Watch a good teacher, and you will see that he does not sit unmoved before his class: he stands
the whole time he is teaching; he walks about, using his arms, his hands and fingers to help him in his
explanations, and his face to express feeling. Listen to him, and you will hear the loudness, the quality and
the musical note if his voice always changing according to what he is talking a- bout.
3 The fact that a good teacher has some of the gifts of a good actor doesn"t mean that he will indeed
be able to act well in the stage, for there are very important differences between the teacher"s work and the
actor"s. The actor has to speak words which he has learnt by heart; he has to repeat exactly the same words
each time he plays a certain part, even his movements and the ways in which he uses his voice are usually
fixed beforehand. What he has to do is to make all these carefully learnt words and actions seem natural on
the stage.
4 A good teacher works in quite a different way. His audience takes an active part in his play: they
ask questions, they obey orders, and if they don"t understand something, they say so, the teacher therefore
has to suit his act to the needs of his audience. He cannot learn his part by heart, but must invent it as he
goes along.
5 As a good teacher presently, you must take your au- dience as your friends, take care of them, help
them and give them enough freedom and space. I have known many teachers who were fine actors in class
but were unable to take part in a stage play be- cause their brains wouldn"t keep discipline: they could not
keep strictly to what another had written.

and international health experts say a new study makes the most convincing case for the benefits of children
being active. They say the research may lead to new guidelines saying youngsters aged between 5 and 16 need
to be active up to 1.5 hours a day.
[2] Experts said the study doesn"t mean children need to be on treadmills (跑步机) or in a soccer
leagues-they just need to be able to run around and play physically, even for short bursts of time.
[3] The study looked at 1,732 9-year-olds and 15-year-olds from Denmark, Estonia and Portugal. Physical
activity was observed for four continuous days. Despite differences among the three coun- tries where children were observed, the benefits of physical activity were the same.
[4] About 40 percent of those observed were reasonably ac- tive, while the rest were sedentary, researchers said. The study found that the benefits of physical activity applied to all children- not just to obese ( 肥胖的)
children normally thought to be at a higher risk.
[5] While much attention has been paid to children"s bad eat- ing habits,this study calls for equal weight to
be placed on activity levels.
[6] "We don"t need to be getting kids running on treadmills in the gym." said Cavil."We need to encourage
kids to play." One of the study"s key findings, he explained, is that it proves the benefit of short bursts of activity, rather than a need for continuous exercises.
[7] But _____ perhaps the greatest factor in children"s physical activ- ity will be the parents themselves."It"s
not just that children should be more active,it"s the whole family," said Weiss."Parents should be role models."

geography, economics, and culture of South America, all without leaving their classroom.
They"re using the Internet to follow the one road South team of adventures on a 14-month bicycle trip
around the continent. Through a program called Reach the World, kids at 60 of the city"s elementary and
middle schools are getting a taste of global citizenship by following the One Road South bikers, a family
traveling in Europe, a bike trek (艰苦跋涉) in Africa, and a Harlem teacher working with scientists in
Antarctica through online videos, journals, and field notes.
Sometimes, students even get to meet the travelers they are following online. Three of the four One
Road South bicyclists recently visited Paulino"s classes present a slide show about the places they plan to
visit.
The students jumped in with questions, asking if the travelers were afraid of wild animals, running out
of food, or going for 14 months without having a girlfriend.
But Reach the World isn"t just for fun. The program aims to integrate technology into the classroom,
to bring subjects like science and social studies to life, and to encourage students to think of them- selves
as global citizens, according to administrators.
Their teacher, Tony Paulino, said his students are beside them-selves with excitement about following
the One Road South bikers. "I believe it speaks to the core desire we all share, to dream, to travel and to
explore," he said.
