For several billion years after the "Big Bang", the earth was still just a cloud of dust.

But they are not looking after the earth very well. They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space. As a result of this, many scientists believe the earth may become too hot to live on. So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.
牛津译林版 高中英语必修第三册 第四单元课本内容
译林牛津英语第三册第四单元课本内容Extended reading, Project, Assessment & Further studyExtended readingRead the adapted version of a scientist’s public lecture about he importance of science.The value of scienceWhen i was younger, I thought science would make good things for everybody. It was obviously useful; it was good. But then during the war I worked on the atomic bomb. This result of science was obviously very serious---it represented the destruction of people of and it put our future at risk. I had to ask myself, “Is there some evil involved in science?”Put another way, what is the value of the science I had long devoted myself to----the thing I had loved----when I saw what terrible things it could do? I thought long and hard about this question, and I will try to answer it today.The first way in which science is of value is familiar to everyone: scientific knowledge enables us to do and make all kinds of things. Of course, if we make good things, it is not only to the credit of science; it is also to the credit of the moral choice which led us to good work. Scientific knowledge is an enabling power to do either good or bad----but it doe snot carry instructions on how to apply it. Such power has obvious value; however, the power is decided by what one does.Another value of science is the intellectual enjoyment it can provide us with.When we look at any problem deeply enough, we feel the excitement and mystery coming to us again and again. With more knowledge comes a deeper, more wonderful mystery, inspiring one to look deeper still. Never concerned that the answer may let us down, with pleasure and confidence we turn over each new stone to find unimagined strangeness leading on to more wonderful questions and mysteries. Thanks to the scientific effort. We have been led to imagine all sorts of things more fantastic than poets and dreamers of the past ever could.I would now like to turn to a third value that science has. The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of great importance. When a scientist doesn’t know the answer to a problem, he is ignorant. When he has an idea as to what the result is, he is uncertain. And when he is pretty sure of what the result is going to be, he is still in some doubt.Now, we scientists take it for granted that it is perfectly possible to live and not know. But our freedom to doubt was born out of a deep and strong struggle against authority in the early daysof science. In order to progress, we must not forget the importance of this struggle; we must recognize our ignorance and leave room for uncertainty. Permit us to question, to bout, to be unsure.It is our responsibility as scientists, knowing the great progress that is the fruit of freedom of thought, to declare the value of this freedom, to teach how doubt is not to be feared but to be welcomed and discussed, and to ensure this freedom for all coming generations.(Adapted from a public lecture by Richard Feynman, an American scientist who won the Nobel Prize in Physics in 1965).A Write a summary of Richard Feynman’s ideas on the value of science.B Feynman believes that “Of all its(science’s) many values, the greatest must be the freedom to doubt.” How do you understand this quote?Project:Making a fact file about a great scientistA: As a class, discuss some scientists that have changed the world. You can think of both Chinese and Western scientists in different fields. Then in groups of four, choose a great scientist to research.B: As a group, research your chosen scientist. Use the ideas below to help you.●Personal information(name, date of birth/death, nationality, childhood, education, etc)●Scientific research (research area and achievements, published works, etc.)●Influence●Interesting factsC As a group, put together your information to make your fact file. Use the example below to help you.
