Many people often say there is more stress in today's society than in years past. In fact, these people are comparing our lives with that of the cave man, who didn't have to worry about the stock market or the atomic bomb. They forget that the cave man worried about being eaten by a hear while he was asleep, or about dying of hunger--things that few people worry much about today.
Actually stress is a normal state of affairs, and it's important that people understand what they are talking about when they speak about stress. Whenever anyone experiences something unpleasant, for lack of a better word they say they are under stress. Yet there is such a thing as pleasant stress--as in the case of the Olympic winner at the moment of his glory, or a conductor as his orchestra performs particularly well. They are just sending out excitement, and they are giving off all the stress hormones exactly the same as if they were in low spirits or had just heard of a death in the family. We call the pleasant or healthy kind "eustress” and the unpleasant or unhealthy kind "distress".
Then how can people deal with stress? The secret is not to avoid it but to "do your own thing". It implies doing what you like to do and what you are made to do at your own speed. For most people, it is really a matter of learning how to live and how to behave in various situations, to decide: “Do I really want to take my father's business or be a musician?” If you really want to be a musician, then be one.
64. What can be inferred from the first paragraph?
A. Modern people experiences more stress than the cave man.
B. The cave man experienced more stress than modern people.
C. People don't suffer more stress today; it's just that they think they do.
D. Modern people have the same worries as the cave man did.
65. In which of the following situations will you feel "eustress"?
A. Your favorite football team has lost an important game.
B. You have failed an important examination.
C. You are informed of an accident of your best friend.
D. You have won the first prize in an English competition.
66 The purpose of writing the passage is to let us know _________________________.
A. stress does not necessarily refer to unpleasant experience
B. distress is what people call the pleasant kind of stress
C. an Olympic winner feels the same stress as one who loses a family member
D. people will feel eustress and distress at the same time
67. According to the passage, how can people deal with stress?
A. Do things that you really want to do.    B. Do whatever you're expected to do.
C. Try to do things successfully.          D. Refuse to do whatever you're told to.

Is war unavoidable? Can war be prevented?

History tells that there were wars, great or small, in every century, in every decade. Throughout the ages, from the Stone age to the Atomic Age, men have been fighting, first with swords and shields(盾), then with guns and cannons, and now, hydrogen bombs and missiles are used for military purpose. But, in spite of all these, it is still my belief that war can be prevented and peace can be won, but it requires the effort of every one of us.

I am sure that we would not like to experience another world war. If it ever happens, two-thirds of the world and much of the civilization which men have gained through time, patience and effort will be destroyed. Will then the remaining one-third of the world be able to survive on its own?

Our task now is not to blame the past, but to plan for the future.

If there is peace in the world, men can use their rockets to explore the mystery of space, their submarines to explore the depth of the sea, their missiles to deliver mails and their fine equipment to penetrate(穿透) the jungles of Africa, instead of using them military.

Governments can use their money to build more schools, so that more children can be educated to be useful citizens. Scientists can use atomic energy to propel (推动) steamships and planes. They can also design new machines to increase the production of goods and thus improve the way of living of the people.

How can a peaceful world be achieved? It requires, in my opinion, the understanding and friendship between all people from all nations. Let no one suffer discrimination by reason of color, race, religion, or national origin. Let the rich support the poor and the strong help the weak.

We know that neither peace nor such a dream world can come true in a day or a month. It may even take decades or centuries. But let us plan and begin now.

1.The best title for this passage is _________.

A.The Past and the Future

B.To Die or To Survive

C.War and Peace

D.Understanding and Friendship

2.In the writer’s opinion, __________.

A.it is too difficult to achieve peace

B.peace can be won through the efforts of all human beings

C.another world war is inevitable

D.wars will always exist in the world

3.We can infer from the passage that __________.

A.wars were not expensive in the past

B.wars can promote the development of weapons

C.things for military use can be transformed to peaceful use

D.as long as there are wars, people’s way of living cannot be improved

4.What should we do to achieve peace?

A.Spend more money educating children.

B.Stop military exploration

C.Call on people to help each other

D.Act from right now on.

5.Which word can best describe the writer’s picture of the future of the world?

A.Optimistic

B.Pessimistic

C.Imaginative

D.Disappointing

A frightening example of the sea’s power saw 125,000 people die in 12 different countries last week. The terrible disaster was caused when a great earthquake sent tsunamis breaking into Indian Ocean coastlines. Various areas in Sri Lanka, Indonesia, Thailand, India, Malaysia and East Africa have been destroyed by the huge waves. Whole towns were simply swept aside by the power of the water. Cars, trains and buildings could not remain steady, not to say the people who stood in the way.

The earthquake measured 9.0 on the Richter scale and occurred off the coast of Indonesia. It was recorded as the fifth strongest since 1900. Scientists said the quake was as powerful as a million of the atomic bombs that were dropped on Japan during the World War II. “This may be the worst natural disaster in recent history because it is affecting so many heavily populated coastal areas.” said Jan Ege-land, a UN official.

Because such waves hardly happen in the Indian Ocean, there is no system in place to warn coastal people who are about to be hit. Tsunami is a Japanese word. They are usually caused by a sudden rise or fall of part of the Earth’s crust under the ocean. Tsunamis often happen in oceans and they are most common in the Pacific.

Tsunamis can be very long, as much as 100 kilometers. They are able to cross entire oceans without losing much energy. One of the most striking facts about tsunamis is that an earthquake on one side of the Pacific Ocean can cause huge waves on the other side.

When the ocean is deep, tsunamis can travel unnoticed at speeds of up to 800 kilometers per hour. They can cross the entire ocean in a day or less. The wave may only be a few meters high in the ocean, but when it is near the shore and reaches shallow water, the wave builds up very quickly in height.

61. How many countries were stricken by the terrible disaster?

         A. 6.                                      B. 12.                          C. 18.                          D. Not sure.

62. All of the following statements are true EXCEPT __________.

Tsunami is a word taken in from Japanese

Tsunamis are quite common in the Indian Ocean

The earthquake measured 9.0 on the Richter scale

No warning system has been set up to watch tsunamis there

63. We can know from this passage that __________.

the earthquake has been the strongest in the last century

the wave soon becomes higher when it reaches the shore

the atomic bombs were more powerful than the earthquake

tsunamis can cross entire oceans with almost the same energy

64. You’ll see the passage in __________ section of a newspaper most probably.

A. Sports                              B. Health                    C. News                      D. Culture

Linus Pauling,the only person who has won two undivided Nobel Prizes,was born in Portland,Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962,long after he had received his Bachelor’s degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it.

He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the “behavior” of molecules(分子) led him from physical chemistry to biological chemistry,especially of the human body. He began with proteins and their main parts,the amino acids(氨基酸),which are called the“building blocks of life”.In 1950,he constructed the first satisfactory model of a protein molecule,a discovery very important to the understanding of the living cell.

During World WarⅡ,Pauling was a member of the Research Board for National Security,for which he was awarded the Presidential Medal of Merit in 1948. However,the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules,he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures.

From then on,Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts,The Nuclear­Test­Ban Treaty,declaring all nuclear tests to be illegal except underground ones,came into effect on October 10,1963,the same day Linus Pauling was awarded the Nobel Peace.

1.From the first Paragraph,we learn that Linus Pauling________.

A.didn’t study hard while in Washington High School

B.is the only scientist who has won two Nobel Prizes

C.was once badly treated in Washington High School

D.chose to study chemical engineering to earn his living

2.Which of the following things did Pauling pay much attention to at first?

A.The “behavior” of molecules.

B.Physical chemistry.

C.Biological chemistry.

D.The human body.

3.Which of the following is legal according to The Nuclear­Test­Ban Treaty?

A.The use of nuclear weapons.

B.Testing hydrogen bomb on the ground.

C.Testing hydrogen bomb on underground.

D.The production of hydrogen bombs.

4.The main idea of the passage is to show________.

A.Linus Pauling’s attitude towards nuclear weapons

B.Linus Pauling’s contributions to the world

C.Linus Pauling’s research on the structure of molecules

D.Linus Pauling’s got the Nobel Prize for Peace
