Warm-up Questions

1) What are the major benefits science and technology have brought to us?

2) Have the development in science and technology also brought about some disasters? Give examples to support your answer.

3) In your opinion, is science mainly a monster or an angel? Explain your answer.

Sample

1) The major benefits science and technology have

brought to us include:

— more advanced facilities and equipment in offices;

— higher yields in agriculture;

— a greater variety of and more nutritious food;

— more effective medicine and better medical treatment;

— a greater variety of entertainment;

— a higher standard of living and easier life;

— longer lifespan for human beings.

2) The development of science and technology has also

brought about some disasters, including:

— more deadly weapons and thus more wars, more victims;

— pollution of nature;

— less communication and thus greater distance between people;

— more people suffering from mental problems;

— higher rate of unemployment;

— more high-tech crimes;

— juvenile delinquency;

— higher crime rate.

3) — I think science is mainly a monster. Science enables

people to develop weapons such as atomic bombs,

chemical weapons, etc. More people thus have become

the victims of wars. People constantly live in fear.

Science sometimes makes people crazy. Children are so

carried away by those wonderfully

made cartoons, computer

fames, etc. that they neglect

their studies.

— I think science is mainly an

angel. Science enables us to

experience and enjoy many things

that our forefathers didn’t even

dream of. Because of science, we

can know what is happening all over

the world without leaving home.

We can order food and other

things at home. We can even

receive education at home. It is

science that has enriched our lives

and improved our standard of

living.

AFTER-CLASS READING

Passage 1 True Love

Key words:

correlation, delicately, intimate, manipulation, measurement, resonance, resonate, a touch of (something), keep something to oneself, on (the) ground of, pick out

Summary of True Love

Mr. Milton Davidson is a computer programmer.

Nearly forty, he wanted to find a true love to marry.

He operates his computer Joe to match him to the

chosen girls. Everything seems all right. But at the

end, Milton was arrested on grounds of some illegal

actions in office, while Joe which was capable of

feeling the same emotions as Milton wanted to take

place of Milton to find the love for himself.

Today, it is very funny to imagine an emotionally

independent machine, but a lot of things we take for

granted now were once considered to be ridiculous.

Passage 2 Back for the Dead

Key words:

deterioration, dispose, equate, extension, facilitation, outline, skeptical, substitute, suspension, be short of, dispose of, equate…with…, in…condition

Summary of Back from the Dead

At the beginning of the passage, the author

gives us a vivid imagined picture of the progress

life scientists will have made.

Then cryonics is induced which is the technique

of deep-freezing a body in liquid nitrogen at the

moment of death in order that bodies can come

back to life.

Some people believe that liquid nitrogen holds

the key to the long-term preservation of the body.

These people look forward to waking up in the

distant future and often believe that death is

merely an illness, which science will eventually be

able to cure. But so far science proves it a wish.

There exists much more disputes concerning

whether this technique works among people.

HOMEWORK

3.3. 我的观点。我的观点。

Writing Practice

People’s Attitudes towards Cloning

To clone or not to clone? That is a

highly controversial question.

Some people assume that as an

amazing technological breakthrough in

science, cloning is helpful for solving

some problems. For instance, with the

help of cloning technology we could

breed and thus preserve (保护) such

endangered wild life as giant pandas (大熊猫) and golden monkeys (金丝猴) .

For another example, cloning may provide cures for many

deadly diseases and a key to prolonging human life (延年益寿) . Apart from these, scientists may increase the yield (产量) of grain crops (粮食作物) to eliminate (根除) world

hunger. Therefore they favor cloning.

However, some people are aware that the costs of

cloning can outweigh ( 胜 过 ) their benefits. They

argue that it may cause moral confusion, ethical issues,

legal problems, and social challenges. While we work

wonders, we may create monsters (怪物) away from

the moral course (道德航线) . People may sacrifice

(牺牲) more to gain little. What if evil (邪恶的) people conducted evil deeds (作恶) with cloning

technology? How could police identify a criminal from a

group of people with the same DNA? In a word, cloning

can have some strong negative influences on human

progress.

In my eyes, human beings should take a cautious attitude

towards cloning. Cloning, like many other inventions and

developments, is a double-edged sword (双刃剑) . The tool

is neutral, but our use of it is not. As a blessing (福音) , it

benefits us. As a curse (灾祸) , it harms us. If it isn’t a must

for diverse reasons, we should be extremely careful about

applying this technology. We can only hope that people, while

making the best use of cloning, will find a satisfactory solution

to the problems caused by it.
