Rachel Carson,a wellknown nature author in America,was happiest writing about the strength and stability of natural systems.Her books mainly described the inter connectedness of nature and all living things.

Completing Silent Spring took Carson four years.First published in The New Yorker in June 1962,the book alarmed readers across America.It described how DDT entered the food chain and accumulated (堆积) in the fatty tissues of animals,including human beings,and caused cancer and genetic damage.

Carson begins by describing exactly these effects in the first chapter,creating strong images and drawing the readers in.As the book continues,she gives various examples of how insecticides(杀虫剂) are not only unsuccessful,but actually very costly and damaging.She also explains about the biological controls which are less expensive and much more efficient.

A single application on a crop,she wrote,killed insects for weeks and months,and not only the targeted insects but countless more,and remained poisonous in the environment even after it was washed out by rainwater.Carson concluded that DDT and other pesticides had definitely harmed birds and animals and had destroyed the entire world's food supply.The book's most famous chapter,A Fable for Tomorrow,described a nameless American town where all life—from fish to birds to apple blossoms to human children—had been “silenced” by the harmful effects of DDT.

The most important effect of Silent Spring,though,was a new public awareness that nature was so easily destroyed by human intervention(干预).Rachel Carson had made a brave proposal:that,at times,technological progress is so basically at odds with(与……不一致) natural processes that it must be prevented.

1.What are Rachel Carson's books mainly concerned about?

A.The relationship between man and nature.

B.The balance of natural systems.

C.The interconnection of nature and living things.

D.The pollution of the environment.

2.According to the text,Silent Spring________.

A.didn't draw the readers' attention when first published

B.mainly describes people's quiet lives in an American town

C.effectively tells people how to keep the balance of nature

D.showed the harmful effects of DDT on nature

3.Rachel Carson thinks that the more efficient way to kill insects is to use ________.

A.DDT

B.human controls

C.biological controls

D.technical progress

4.The publication of Silent Spring makes people ________.

A.understand the author's outstanding writing talent

B.realize the importance of technical progress

C.aware of the necessity of environmental protection

D.rethink the harmful effects of developing industry

What is critical thinking? To a certain degree, it's a matter of logic -- of being able to spot weakness in other people's arguments and to avoid them in your own. It also includes related skills such as distinguishing fact from opinion and assessing the soundness of evidence.

In the broad sense, critical thinking is focused, organized thinking -- the ability to see clearly the relationships among ideas. 1.__. The greatest thinkers, scientists, and inventors have often taken information that was really available and put it together differently to produce new ideas. That, too, is critical thinking.

_2._. As the class goes on, for example, you will probably spend a good deal of time organizing your speeches. While this may seem like a purely mechanical (机械的) exercise, it is closely connected with critical thinking. If the structure of your speech is loose and confused, chances are that your thinking is also disordered and confused. If, on the other hand, the structure is clear, there is a good chance your thinking is too. Organizing a speech is not just a matter of arranging your ideas you already have. 3.___.

What is true of organization is true of many aspects of public speaking. _4._. As you work on expressing your ideas in clear accurate language, you will improve your ability to think clearly and accurately. __5. As you learn to listen critically to speeches in class, you will be better able to assess the ideas of speakers in a variety of situations.

If you take full advantage of your speech class, you will be able to develop your skills as a critical thinker in many circumstances. This is one reason public speaking has been regarded as a vital part of education since the days of ancient Greece.

A.Rather, it is an important part of shaping the ideas themselves.

B.This may seem take a lot of time, but the rewards are well worth it.

C.It may also help you to know that there is no such thing as a perfect speech.

D.It has often been said that there are few new ideas in the world, only reorganized ideas.

E . If you are wondering what this has to do with your public speaking class, the answer is quite a lot.

F. The skills you learn in your speech class can help you become a more effective thinker in a number of ways.

G. As you study the role of evidence and reasoning in speechmaking, you will see how they can be used in other forms of communication as well.

More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine.

The prize for Dr Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a £900,000 cheque. The Nobel Assembly described IVF as a "milestone in modern medicine".

With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF - leading to the birth of the world's first test tube baby. Dr Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples.

It was a scientific breakthrough that transformed the lives of millions of couples. They said: "His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This condition has been afflicting a large percentage of mankind including more than 10% of all couples worldwide."

Louise Brown, the world's first test tube baby, made international headlines when she was born in Oldham, Gtr Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.

Ivf-in-vitro fertilisation is the process whereby egg cells are fertilised outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five — the same as healthy couples who conceive naturally.

Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955.He once said: "The most important thing in life is having a child. Nothing is more special than a child." With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn

Hall clinic in Cambridge shire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain now undergo IVF and 11,000 babies are born as a result of the treatment.

But his work attracted widespread criticism from some scientists and the Catholic Church who said it was "unethical and immoral".

Martin Johnson, professor of reproductive(生殖的) sciences at the University of Cambridge, said the award was "long overdue". He said: “We couldn't understand why the Nobel has come so late but he is delighted - this is the cherry on the cake for him.”

Professor Edwards was too ill to give interviews but a statement released by his family said he was "thrilled and delighted".

1.What is Robert Edwards‘ contribution to science?

A. Challenging a disease which stops human having a baby.

B. Seeing the wonder of the first tube baby growing

C. Enabling millions of couples to live a better life.

D. Helping couples with infertility to have tube babies.

2. What does the underlined word “afflicting”(Paragraph 4)most probably refer to?

A. Troubling B. Developing

C. Improving D. Confusing

3. Why did Professor Edwards begin his research on tube baby?

A. Because he thought it of great significance to have a child in life.

B. Because the birthrate around the world was unexpectedly low then.

C. Because a special child did make a difference to an ordinary family.

D. Because his fellow scientist wanted to give hope to the unlucky couples.

4.It can be inferred from Paragraph 8 and Paragraph 9 that ___________.

A. some people envied Professor Edwards for his being awarded.

B. different opinions were voiced on Professor Edwards‘ finding.

C. Professor Edwards deserved the prize for his breakthrough.

D. the prize was late because the finding was first considered immoral.

5. What might be the best title for the passage?

A. Life Stories of Robert Edwards

B. Preparations for Having a Baby

C. Nobel Prize for IVF Expert Edwards

D. Treatment of Infertility in a Lab

It was a weeknight. We were a half dozen guys in our late teens, hanging around “the flat” — as usual. The flat was poorly furnished, which, after some time, grew tiresome. We wanted action.

We got in a car, big enough for all of us to crowd into — and off we went, in search of adventure. We soon found ourselves at Blue Gum Corner, a place named after the huge old blue gum tree that stood by there, a well-known local landmark. It stands at a minor crossroad leading to our town. The trunk is tall and smooth with no handholds for climbing. About six metres from the ground the first branch sticks out over the road. We parked beneath the huge old tree and discussed what we might do. All of a sudden we hit upon an idea — a hanging! I was chosen as “hangee”.

The plan was quite simple. As I stood upon the roof of the car, the rope(绳子) was threaded down my jacket through my collar and down one leg of my jeans. I put my foot through the loop at the bottom. There I hung, still. The boys rolled about laughing until, a car, I hear a car! Before they ran to hide in the nearby field, they gave me a good push so that “the body” would swing as the car drove by.

To our disappointment, the car simply turned off for town without even slowing. The boys came out of their hiding places and we discussed the situation. Surely they had seen me, hadn’t they? Then we heard another car. The act was repeated, but still without any obvious reaction. We played the game about five or six times, but as no one seemed to notice, we abandoned the trick.

What we did not know was that every car that had passed had unquestionably seen “the body” and each one, too scared to stop, had driven directly to the local Police Station. Now at that time of the night, the local policeman was sound asleep in his bed, so the first person sent to the scene was the traffic officer that happened to be on duty that particular night. He had been informed that some person had been killed, by hanging, at Blue Gum Corner. When he arrived, the body was gone! And he was hearing “unnatural sounds” from the surrounding area. As far as he knew, some fierce animal was hiding in the field before him, possibly dragging a body behind him — and we thought we were scared!

He went to his radio and made a call that really began to worry us. I lay so close that I could hear every word. He called for the “armed police” and a “dog team, better make it two” and he had a “serious situation” at Blue Gum Corner. Then the police officer arrived. After a briefing from the traffic officer he decided not to go into the field until armed police and dog teams arrived. Now two spotlights were on the field and none of us could move.

As luck would have it, police cars cannot leave their spotlights on all night without charging their batteries. So, after a time, the two officers began lightening the field by turns, allowing us the opportunity to move on our fours for freedom. One by one, we all managed to steal away and make our way home. Behind us we left what must have looked like a small city of lights, police cars, roadblocks, barking dogs, armed officers and an old rope hanging from a tree.

When I think back to that night, to that tree, to what the drivers of the cars think happened, to what police believe happened, and to what I know happened, I am reminded of a simple truth — our eyes see darkness and light, color and movement, our ears hear only vibrations(振动) in the air. It is how we explain these vivid pictures that shapes our “reality”.

4.The boys managed to escape from the field when ______.

A. the two police cars were being charged

B. the police officer was taking over the duty
