Which life forms are most likely to develop on a distant planet? Recent developments in astronomy have made it possible to detect planets in our won Milky Way and in other galaxies. This is a major achievement because, in relative terms, planets are very small and old not emit light. Finding planets is proving hard enough, but finding life on them will prove infinitely more difficult. The first question to answer is whether a planet can actually support life. In our won solar system, for example, Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions, and even here it has taken more than four billion years for plant and animal life to evolve.Whether a planet can support life depends on the size and brightness of its star, that is its 'sun'. Imagine a star up t twenty times larger, brighter, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life. Alternatively, if the star were small, the life-supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. But how would we find such a planet? At present, there is no telescope in existence that is capable of detecting the presence of life. The development of such a telescope will be one of the great astronomical projects of the twenty-first century.It is impossible to look for life on another planet using earth-based telescopes. Our own warm atmosphere and the heat generated by the telescope would make it impossible to detect objects as small as planets.Even a telescope in orbit round the earth, like the very successful Hubble telescope, would not be suitable because of the dust particles iron solar system. A telescope would have to be as far away as the planet Jupiter to look for life in outer space, because the dust becomes thinner the further we travel towards the outer edges of our own solar system. Once we detected a planet, we would have to find a way of blotting out the light from its star, so that we would be able to 'see' the planet properly and analyze its atmosphere. In the first instance, we would be looking for plant life, rather than 'little green men'. The life forms most likely to develop on a planet would be bacteria. It is bacteria that have generated the oxygen we breathe on earth. For most of the earth's history they have been the only form of life on our planet. As Earth-dwellers, we always cherish the hope that we will be visited by little green men and that we will be able to communicate with them. But this hope is always in the realms of science fiction. If we were able to discover lowly forms of life like bacteria on another planet, it would completely change our view of ourselves. As Daniel Goldin of NASA observed, 'Finding life elsewhere would change everything. No human endeavor or thought would be unchanged by it."参考译文天文学方面最新发展使得我们能够在银河系和其他星系发现行星。

新概念英语第三册 51-55 课后作文标准答案

Lesson 51 Predicting the futureKey to CompositionA possible answerflan and ideas for composition (a)Titles Computers in 20 years' time - Introduction: Predicting what computers will be like — guessing gameDevelopment: Development so fast — computers already smaller, more powerful, cheaper than ever — in 20 years, what? Let's speculate1 Everyday shopping by computer — virtual-reality shopping2 Education—computer-notebooks3 Travel- computer -driven aircraft, cars, lorries, etc.4 Medicine and health—brain surgery — computer-operated limbs Conclusion: Who knows? — wait and seeCompositionPredicting what computers will be like in 20 years' time or what they will be able to do is a guessing game. If Leon Bagrit could not predict everything, what chance have I got? However, because prediction is just a calculated guess, I will try!The development of the computer since the 1960s has been very fast. Prom large mainframe computers which filled whole rooms to small lap-top computers which you can carry in a shoulder bag or large handbag, it has taken only forty years. Computers are already smaller, more powerful and cheaper than they have ever been. So what might happen in the next twenty years? Let's speculate.In twenty years' time it's possible that many people will be doing their everyday shopping by computer. The "virtual-reality" shop will be available through your TV set. You will be able to "walk through" your supermarket on screen, click or tick what you want, and then order it — and it will be delivered. In education, most students could be using computer-notebooks which make notes for them as they listen to a lecture or watch a demonstration experiment. In the world of travel, aircraft already have computer systems that will con-trol auto-pilot In twenty years' time, computers could actually pilot aircraft — with no need for a real, live human pilot at all. Computers already help doctors diagnose disease and other health problems, and help in the control of body systems during opera-tions. What else might they do in the future? They might actually control certain kinds of surgery (brain surgery, for example) where the human hand cannot always keep still enough, and power computer-operated limbs.So there are some ideas. But who knows what might really happen? No one. No one can see into the future. We shall just have to wait and see. (307 words)Lesson 52 Mud is mudKey to CompositionA possible answerPlan and ideas for composition (a)Title: A day's shoppingIntroduction: Looking forward to day out — wanted to get new clothes — last Friday Development: Got up usual time —caught bus to centre of town —a list of purchases —something to wear to friend's wedding — pair of shoes to go with new clothes — within an hourhad most important things on list Then most difficult part of day — "Birthday present for Pat" —a book Spent 2 hours in one large book shop — failed — bought three for self!Conclusion: How I felt when I got home CompositionFor me, a day's shopping is the best way I think of to pass a day away from college or work. I have been looking forward to a day out shopping for weeks because I have wanted to get some new clothes for ages, so last Friday I took a day off.I got up at the usual time (as if I were going to work or college) because for me shopping is as serious as work. Before I left the house I made sure I put on a good pair of walking shoes and then caught the bus into the centre of the town.Some people visit all the shops in the hope that they will find what they want at the prices they want to pay. Not me: I'm one of those shoppers who has a list of purchases — and with a fairly good idea of how much I want to pay.The first thing 1 wanted was something to wear to a friend's wedding next month — and I didn't want to pay very much- I found just what f wanted in the second shop I visited. And in the second shoe shop I visited, I found a pair of shoes that would go with the new clothes and which I could wear to work afterwards. Within an hour I had bought the most important things on my shopping list. I was so pleased!But then came the most difficult part of the day. The third thing on my shopping list was "Birthday present for Pat". I like to give her a present but it is always so difficult. This year, I decided, I would buy her a book. Do you know how long I spent in one large book shop? Two hours! And even then I didn't get her a book — although I bought three for myself IBy the time I got home, it was six o'clock. I was absolutely exhausted, but pleased that I had managed to buy two things on my list.(337 word)Lesson 53 In the public interestKey to CompetitionA possible answerPlan and ideas for composition (6)Title: The work of a policemanIntroduction: In Britain —people —different attitudes to police —generally appreciate them (not criminals!)What do police do?Development: Number of jobs in one:Traffics ;keeping the peace; solving crime; helping to keep order in emergencies — air crashes, fires, road accidents, etc. Conclusion: Police do excellent job — don't envy them Composition In Britain, people have different attitudes to the police. Most people generally appreciate them and the job they do — although there. are certain people (including criminals, of course) who do not believe that the police should have the power that they do.What does a policeman actually do? It is not an easy job to describe. After all, a policeman has a number of jobs in one. A policeman often has to control traffic, either on foot in the centre of a town, or in a police car on the roads. Indeed, in Britain, he might be in the Traffic Police and spend all, or a lot of, his time driving up and down main roads and motorways. A traffic policeman has to help keep the traffic moving, stop speeding motorists and help when there is anaccident. 'A policeman has to help keep the peace, too. If there is a fight or some other disturbance, we expect the police to come and assess the situation and restore order. And they often have to deal with situations at great risk to themselves and their own safety.We expect the police to solve crimes, of course, so an ordinary policeman, even if he is not a detective, will often have to help look for and arrest criminals.And who do we call when there is an emergency —an air crash, a fire, a road accident, or a burglary? We call the police. So a po-liceman has to be prepared to face any unpleasant emergency that may happen in the modern world.The police do an absolutely necessary job, they do it extremely well and I support them, but I do not envy policemen. 1 do not think that 1 could ever do the job of a policeman. (296words)Lesson 54 Instinct or cleverness?Key to CompositionA possible answerPlan and ideas for composition (b)Title: Our efforts to control pestsIntroduction: What are "pests"? — see dictionary definition — always been difficult to control or exterminate themDevelopment: Insects: ants, wasps, locusts, (plague), beetles that damage woodwork. . . damage property, devour our crops, . . . —other pests —mice, rats —eat food —spread disease —efforts to control pests — insecticides and pesticides — poison —traps . . . . , . . . . , .For farmers, even certain birds are pests — gulls, pigeons, etc. — follow at sowing time and eat seeds —' scarecrows to frighten birdsConclusion: Tried almost everything — some pests held in check other still a major problem (e. g. locusts) . .CompositionAccording to my dictionary, "pests" are "small animals or. insects that harm or destroy food supplies". But, for me, they are more than that: they are insects and small animals that spread disease and damage property, too. Whatever they do and however you define them, pests have been a major problem to man throughout history. Man has tried to control or exterminate these creatures, but neverwith very much success.In some ways, insects are the worst pests. Ants, locusts and beetles damage property, woodwork, crops and harvest, and. in this century we have sprayed crops with insecticides and pesticides to protect them from insects. The problem now is that there are some in-sects that have become immune to pesticides. Rats and mice eat our food supplies too and spread disease, and people have tried to kill or catch them with poison or traps. But again, they are still with us- We. haven't managed to exterminate them.Let's not forget, however, that for farmers, certain birds are "pests" too. In Britain, seagulls, pigeons and other birds often fly down in their hundreds (or even thousands) to pick up seeds when farmers are planting crops. Years ago, fanners used to stand scare- crows in the fields to frighten away birds, but I'm not sure how effective they were.We have tried different things, then, to control pests, and we have managed to hold some pests in check. However, some are a big problem, both in the major industrial nations and in the Third World. While locusts are a terrible problem in countries like Sudan and Ethiopia, rats are still a problem in most large cities in the world. We might control pests to a certain extent, but we shall never get . rid of them. (292words)Lesson 55 From the earth: GreetingsKey to Composition.A possible answerPlan and ideas fair composition (a)Title: ExtraterrestrialsIntroduction: Remember "ET"? Ideas about extraterrestrialsDevelopment: But creatures with incredible intelligence and no form? How deal with them? Not benevolent? Stories of extraterrestrials aliens landing —have scientists studied them? Extraterrestrials helping scientists? Stories just rumours?Conclusion: Extraterrestrials out there in space? Perhaps one day we'll know: change our view of everything CompositionDo you remember ET in the Film ET, the Extraterrestrial'! If you do, you will know that the common picture of extraterrestrials is that they will look rather strange —for instance, they might have big eyes and funny feet and be a strange colour — but they will still somehow look like living creatures from earth. At the same time, of course, we believe that they will probably have incredible powers —like ET's power to heal injuries and to come alive again. Many science-fiction stories and films have shown aliens or extraterrestrials like this. They may somehow look like strange earth creatures, therefore, but they are benevolent.But what if extraterrestrials —beings from other planets —are creatures with incredible intelligence and with no form, that is, with no body form like earthly creatures? They might be almost "living thoughts''. How would we greet them? How would we deal with them? And what if they are not benevolent? In other words, what if they really want to take over the earth?There are stories that extraterrestrials or aliens have already crashed on earth m spacecraft (flying saucers) and that scientists have studied them. There are even more fantastic stories that scientists are already learning from extraterrestrials new knowledge which will help us build incredible spacecraft to fly to other planets and beyond. Stories like that must surely be just rumours.Perhaps one day we will know if there really are extraterrestrials out there in space, and if there are, we will know what they look like and what they think of us. Will they really be little green men? Or will they be giants? Or perhaps they will be so small that we can hardly see them? Will they be friendly? Or will they want to take over the earth? Who knows? One thing is certain. If we were ever to discover that there are extraterrestrials out there, the discovery would completely change our view of the universe and ourselves.(329 words)。

Which life forms are most likely to develop on a distant planet?Recent developments in astronomy have made it possible to detect planets in our own Milky Way and in other galaxies.天文学方面最新发展使得我们能够在银河系和其他星系发现行星。

This is a major achievement because, in relative terms, planets are very small and do not emit light.这是一个重要的成就，因为相对来说，行星很小，而且也不发光。

Finding planets is proving hard enough, but finding lifeon them will prove infinitely more difficult.寻找行星证明相当困难，但是要在行星上发现生命会变得无比艰难。

The first question to answer is whether a planet can actually support life.第一个需要解答的问题是一颗行星是否有能够维持生命的条件。

In our own solar system, for example, Venus is far toohot and Mars is far too cold to support life.举例来说，在我们的太阳系里，对于生命来说，金星的温度太高，而火星的温度则太低。

新概念第三册自学导读Lesson55

Excel如何实现局域网内共享工作簿协作Excel数据功能强大，非常好用，但平常用的时候大家总会觉得共享性比较差，不能像系统软件那样进行网络共同协作使用同一个文件。

其实，Excel也有提供局域网能共享协作的功能。

共享工作簿功能共享工作簿，可以为多用户编辑提供的现有工作簿。

但是共享工作簿并不支持所有功能，它支持以下功能：1）可以插入整行和列。

2）可以按数字、文本或日期进行排序或筛选，应用内置筛选器，然后通过使用“搜索”框进行筛选。

3）在单元格值发生变化时可以使用现有条件格式。

4）键入新值时可以使用数据验证。

5）可以查看现有图表和报表。

6）可以查看现有图片和对象。

7）可以使用现有超链接。

8）可以查看现有绘图和图形。

9）可以使用现有密码。

10）可以使用现有保护。

11）可以使用现有分级显示。

12）可以查看现有分类汇总。

13）可以查看现有模拟运算表。

14）可以查看现有报表。

15）工作簿中的现有切片器在共享工作簿后可见，但不得将其更改为独立切片器，或者重新应用于数据透视表数据或多维数据集函数。

应用于切片器的任何筛选保持不变，无论切片器在共享工作簿中是独立的还是用于数据透视表数据或多维数据集函数。

16）工作簿共享之后，工作簿中将显示现有的迷你图，并且将作出更改，以反映更新的数据。

但是，您不能创建新的迷你图、更改其数据源或修改其属性。

17）可以运行访问可用功能的现有宏。

可以将共享工作簿的操作记录到存储在其他非共享工作簿的宏中。

18）正确地计算现有数组公式。

设置共享文件夹在电脑里面设置一个共享文件夹，用来放置共享Excel文件，如建立一名为“20161024”的文件夹，然后鼠标右键菜单“属性”，进入文件夹属性设置，进行共享设置。

设置完成之后，我们就在“网络”中可以看见共享的文件夹“20161024”。

共享工作薄设置打开我们需要共享的工作薄，选择“审阅”——“共享工作薄”设置共享。

在“共享工作薄”对话框从勾选“允许多用户时编辑，同时允许工作簿合并（A）”，确定退出就好了。
