IV. Translation

A.(Refer to the relevant part of the Chinese translation)

B.In September 1995, anti-hydrogen atom—an anti-matter atom—was successfully developed in European Particle

Physics Laboratory in Switzerland. After the startling news spread out, scientists in the West who were indulged in the research of anti-matter were greatly excited. While they were attempting to produce and store anti-matter as the energy for spacecraft, they raised a new question: Many of the mysterious nuclear explosions in the recent one hundred years are connected with anti-matter. That is to say, these hard-to-explain explosions are tricks played by anti-matter. They are the ―destruction‖ phenomenon caused by the impact between matter and anti-matter.

WRITING?STRATEGY?DEFINITION

I. Complete the following definitions with the help of dictionaries.

1. To bribe means to influence the behavior or judgment of others (usually in positions of power) unfairly or illegally

by offering them favors or gifts.

2. Gravity is defined as the natural force by which objects are attracted to each other, especially that by which a large

mass pulls a smaller one to it.

3. The millennium bug refers to the computer glitch that arises from an inability of the software to deal correctly with

dates of January 2000 or later.

4. Globalization is understood as the development so as to make possible international influence or operation.

II. Write a one-paragraph definition of the following words.

1. hypothesis

A hypothesis is an idea which is suggested as a possible way of explaining facts, proving an argument, etc.

Through experiments, the hypothesis is either accepted as true (possibly with improvements) or cast off.

2. science

Science is defined as the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.

3. superstition

Superstition refers to a belief which is not based on reason or fact but on old ideas about luck, magic, etc. For example, it is a common superstition that black cats are unlucky.

4. pessimism

Pessimism is a tendency to give more attention to the bad side of a situation or to expect the worst possible result. A person with pessimism is a pessimist who thinks that whatever happens is bad.

5. individualism

Individualism is the idea that the rights and freedom of the individual are the most important rights in a society.

It has a bad sense in that little attention is paid to the rights of the collective or a good one in that independence is emphasized rather than dependence on others.

B. The Standard Model of particle physics is an unfinished poem. Most of the pieces are there, and even unfinished, it

is arguably the most brilliant opus in the literature of physics. With great precision, it describes all known matter –all the subatomic particles such as quarks and leptons – as well as the forces by which those particles interact with one another. These forces are electromagnetism, which describes how charged objects feel each other‘s influence: the weak force, which explains how particles can change their identities, and the strong force, which describes how quarks stick together to form protons and other composite particles. But as lovely as the Standard Model‘s description is, it is in pieces, and some of those pieces – those that describe gravity – are missing. It is a few shards of beauty that hint at something greater, like a few lines of Sappho on a fragment of papyrus.

B. The five scientists who won the 1996 Nobel Prize point out that the present prosperity and development are

based on the fruits of basic scientific research and the negligence of basic scientific research will threaten human development of the 21st century.

EU countries noticed that one of their weaknesses is ―insufficient investment in research and development.‖ Korea and Singapore do not hesitate to pour money into research and development. The developed countries in the West have used most of the scientific and technological development resources for the research and development of new and high technology. This has become an obvious trend at present. It is evident from the experiences of various countries that new and high technology can create and form new industries, open up and set up new markets. The innovation of traditional industries with new and high technology is a key method to strengthen the competitive competency of an enterprise.

VI. Grouping:

B. There are only two forms of human spiritual creation: science and poetry. The former gives us convenience; and

the latter gives us comfort. In more common words, the former enables us to have food to eat when we are hungry;

and the latter makes us aware that eating is something more than eating, and it is very interesting as well. To have science without poetry, atomic bomb will be detonated; to have poetry without science, poets will starve to death.

Scientists should not despise poets; and poets should not remain isolated from scientists. If the two fields conflict each other, human beings would be on the way to doom. In fact, the greatest scientists like Newton, Einstein and Mrs.

Currie were all endowed with poetic spirit. I assert that in observing the apple falling to the ground, Newton not only discovered the gravity of the earth, he also wrote a beautiful poem.

V. Grouping

A.Human reason:

guilty of hubris, cramped imagination, commonsense logic, an ignorant man

B.Differences between art and science:

different in their methods and in their ends, a scientific hypothesis can be proven, new combinations of old materials, transform the ordinary into extraordinary, a practical extension into technology, the sense of an ending

B. At present there exist two conflicting tendencies towards the development of science and technology. The

opponents of science hold that the development of modern science has not brought blessings to human beings, instead it has brought human beings to the very edge of disaster and peril. On the other hand, the proponents of scientific and technological progress maintains that the crises facing human beings today—such as environmental pollution, ecological unbalance, natural resource exhaustion—are the natural consequences of the development of science, and the solution to which lies in the further development of science. Both of the above tendencies are reasonable in a sense with their respective one-sided view. If we view the development of modern science and technology from the point of view of our times and with dialectic viewpoints, we can find out that the problem facing modern science and technology is not how to understand the progress of modern science and technology, but how to find out the theoretical basis for the further development of science and technology in order to meet the needs of the times.

V. Grouping

A.Attitudes toward science:

expect to be helped by science and only by science, the superstition of science, the hatred of science, the one great landmark on the road to truth

B. Human beings have long been attempting sending unmanned devices, called interstellar probes, into the outer

space to understand the changes of climates, geological structures and the living beings on the stars and planets out there. A probe is usually sent into the orbit of the earth by ―riding‖ a spacecraft or carrier rockets. After its orbital adjustments are made, the rocket engine is ignited and the probe continues its journey to the orbit of the other star or planet. With the rocket engine broken off, the probe immediately spreads its solar-cell sails and antenna, controlling its posture with sensors. When convinced that it is in the orbit of the targeted star, the probe starts its propeller and flies to the preset destination.

B. The energy released from nuclear fusion is much more than that from nuclear fission, and the radioactivity given

out from fusion is only one hundredth of that from fission. The major fuel used for nuclear fusion is hydrogen and

its isotopes, deuterium and tritium, among which deuterium could be directly extracted from sea water. The energy of deuterium contained in one liter of sea water is equal to 300 liters of petroleum. In the ocean there are about 35,000 billion tons of deuterium, which could be used for more than one billion years. Compared to the fission energy, the fusion energy on the earth is nearly limitless.

B. On December 14, 1985, the underwater robot ―Seaman I,‖ designed and manufactured independently by our

country, dived to the sea bottom in the Bay of Daliang. Equipped with several electric screw propellers, it could advance, retreat, make a turn, ―creep across‖ and stay in suspension at any depth in water. With a new type of microbeam TV, it was able to see clearly the target within 20 meters across the pitch-dark seafloor. The sonar ―ear‖ and the over-five-meter-long mechanical hand enabled the robot to perform underwater operation at will under the control of the computer.
