If there are a million technical civilizations in the Milky Way galaxy, the average separation from civilizations is about 300 light-years.Since a light year is the distance that light travels in one year(a little under 6 trillion miles), this implication that the one-way transit time for an
interstellar communication from the nearest civilization is some 300 years.The time for a query and a response would be 600 years.This is the reason why interstellar dialogues are much more likelythan interstellar monologues.In first sight，it seems
remarkably selfless that a civilization might broadcast radio messages with no hope of knowing, at least in the immediate future, they have been received and what the response to it might be.But human beings often perform very alike actions as, for example, burying time capsules to be covered by future generations, or even in writing books, composing music and create art intended for posterity.A civilization that had been aided by the receipt of such a message in its past might wish similarly benefit from other emerging technical societies.Unit 3

第二篇：大学英语四六级短文改错
Until the very latest moment of his existence, man has been bound to the planet on which he originated and
developed.Now he had the capability to leave that planet ___1___ and move out into the universe to those worlds which he has
known previously only directly.Men have explored parts of ___2___ the moon, put spaceships in orbit around another planet and
possibly within the decade will land into another planet and ___3___ explore it.Can we be too bold as to suggest that we may be ___4___ able to colonize other planet within the not—too—distant ___5___ future? Some have advocated such a procedure as a solution to the population problem.ship the excess people off to the
moon.But we must keep in head the billions of dollars we ___6___ might spend in carrying out the project.To maintain the earth’s population at its present level.we would have to blast off into space 7,500 people every hour of every day of the year.Why are we spending so little money on space ___7___ exploration? Consider the great need for improving many ___8___ aspects of the global environment, one is surely justified in
his concern for the money and resources that they are poured ___9___ into the space exploration efforts.But perhaps we should look at both sides of the coin before arriving hasty conclusions.___10___
答案：
1.had-> has
2.directly-> indirectly 3.into->onto / on 4.too-> so 5.planet-> planets 6.head-> mind 7.little-> much 8.Consider-> Considering 9.they-> / 10.arriving 后加at 或 arriving-> reaching
考点例析：
例1： If his aim is inaccurate and he scores a goal, enjoys S3.____ the hunter’s triumph of killing his prey.解析：这是由一个条件状语从句引导的复合句。但主句只有谓语动词enjoys，缺少主语，因此要步上主语。根据从句的his aim可推断应该加上主语he。
例2：Nuclear physicists who interested in the structure of 5._________ atoms cannot observe protons, electrons and neutrons
directly.解析：如果将who后面的部分作定语从句，那么它绝少谓语，故将who去掉，此时分词短语interested in直接作定语修饰前面的physicists。或在who后加are，补全定语从句。
例3：This alliance guarantees that all leprosy patients, even they S6.______ are poor, have a right to the most modern treatment.解析：even是副词，后面不能直接跟句子，根据句子的意思，应该在even后加if或though。
巩固与拓展
1.A student of music needs as long and as arduous a training
to become a performer a medical student needs to become __________ a doctor.2.This trip can be found in a booklet, Passport to the Pub:
The Tourists’ Guide to Pub Etiquette, a customers’ code of
conduct for those want to sample “a central part of British ________ life and culture.3.When a new robot is introduced to a small suburban
factory, a Shinto priest is invited to inaugurate._________
4.Since the law made easier to get a divorce, the number of __________ divorces has increased.5.Another changehas been caused by the fact people are _______ living longer nowadays, and many old people live alone
following the death of their partners
巩固与拓展：
1.在performer后加as
此处为同级比较，固定结构为as...as...，而原句比较的对象a medical student前缺少连词as。
2.want-> wanting或those后加who
for为介词，后面的宾语时代词those，不可再跟主谓结构。故将want改为wanting，用现在分词短语作定语修饰those，或者在want前加who构成定语从句修饰those.3.inaugurate后加it
4.made后加it
句子主语是law，谓语是made，easier是宾语补足语，逻辑宾语是to get a divorce，可见此句缺少形式宾语it.5.fact后加that
fact之后的部分是同位语从句，补充说明fact，其引导词不能省略。
综合训练
1.small-> smaller
该句后面有than，所以前面应该是smaller。
Many peolpe than ever are drinking coffee these days--but in small 1.____ quantities than they used to.Some manufacturers of coffee makers are
trying to make advantage of this trend by developing diminutive machines 2.___ that brew（煮）smaller amounts of coffee.Two U.S appliance companies---Black&Decker, basing in Twson, Maryland, and Toastmaster Inc.3.___
of Columbia, Missouri---has recently introduce ”drip" Coffee makers that 4.____ brew one or two cup servings of coffee.Neither of the products brew the 5._____ coffee directly into a cup or mug, eliminating the need for a separate
carafe.Since many people make a pot of coffee in the morning and drink 6.____ only a single cup, the new cofee makers should reduce the wasted coffee.Black&Decker’s Cup-at-a-Time spends $27, while Toastmaster’s Coffee 7.___ Break retails for $20.Black&Decker also makes a coffee maker drips coffee directly into a 8.____ carry-around thermal carafe.The carafe, a glass vacuum bottle, is supposed to keep the coffee fresh for hours.The product, called the Thermal Carafe coffee-maker, comes with a built-in lid that opens during the brewing
process, closes when it is completed.There are several models, including 9.____ one that firs under the counter, ranging from $60 to $110 at price.10
1.small-> smaller
该句后面有than，所以前面应该是smaller。
2.make-> take
take advantage of 为固定搭配，意思为“利用”，与其同样意思的词组还有make use of。
3.basing-> based
base和它的逻辑主语是被动关系。be based on sth 以什么为基础 base sth on sth …以…为基础
what are you basing this theory on ?你这种理论的根据是什么？
4.has-> have
句子的主语是two US appliance companies, 谓语动词要用复数。
做短文改错先找句子主干：判断时态，单复数
5.Neither-> Both
根据文章的中心观点，这里时说两种产品都如何。故要用both 先通读全文，了解文意
6.and-> but
本句的意思应该是：大部分人都是早上煮一壶咖啡 但却只喝一小杯。并列句前后应该是转折关系。
7.spends-> costs
spend的主语必须是人，此处主语是物，应该用cost表示 “该物花费了多少”。
8.maker 后加that或which
一个句子在没有连词的情况下不能带有两个谓语，本句的谓语是makes，而drips和之后的部分应该是定语从句修饰coffee maker，又由于先行词在从句中作主语，所以引导词不能省略。
9.closes前加and
在英语中，用逗号连接两个独立的主谓结构是不对的，所以要在closes前加and。
10.at-> in
表示“在...方面”，使用介词in．
1.有比较级than一定注意形容词为比较级
第三篇：英语改错问题
白话英语(Plain English)难字(big word)
过时的字眼(old-fashioned word)We hope to visualize world peace in the future.(我们希望将来看到世界和平)charitable organization 慈善机构 We are trying to make everyone equal.噜苏或绚丽的字眼（flowery or wordy）
At this point in time, we should pull together for our goal.(现在我们应该为我们的目标团结一致）at this point in time = now 意义的重复或用字的多余(redundant)Enclosed please find the report of the meeting(即：附上会议报告，请查收)Mankind are considered the smartest animals in the world Police officers should treat citizens with courtesy Stewardesses for international regions may get jet lag sometimes.（国际航线的空中小姐有时会有时差疲惫的现象）
侮辱的味道（insulting words 或 slur）
For your information, the word you just used is derogatory（或 inappropriate）to describe someone of my race.（只想让你知道：你刚刚所用的字，来描写我的族群，是很不合适的）英语改错问题
首先要说的是：每次改错要你指出错误的地方肯定有错，绝对不会没错，而且肯定在这行，不会到前面或者下面去！
然后要说的是：从革来看，改错的判卷方法改变了。找出错误0。5分，改对错误0。5分 有错的一句话，最多10个英语单词，大家首先按词性来划分一次 名词错误的可能（1）名词单复数
只有这1种可能，而且到现在的改错，我就记得就1次单复数没考，其他场次必考！形容词错误的可能
（1）意思颠倒，要改成反义词
这个错错每次改错题目都有，所以看到错的句子有形容词，先上下文看看，有没有意思反了（2）词性错误
2个形容词在一起，那肯定有一个是修饰另外一个的，所以要改成副词 介词错误的可能性
（1）固定短语的搭配问题，不如key to,answer to, be faced with等
这个错错每次改错题目都有，所以看到错的句子有介词，先看左右，有没有搭配错误 连词错误的可能性（1）承上启下的错误
有时候，表示递进的，但题目中给出even if，所以要把if去掉；有时表原因的，但题目中是therefore，所以要改成because。这样的错误也时常出现，但不是每次出现（2）非限制性宾语从句只能由which引导，题目中很会用that来误倒 代词错误的可能性
（1）代词与先行词不一致
前面说了是单数，后面用了them，所以要改成it。这类的错误也经常发生 动词错误的可能性（大头！）（1）时态错误
明明文章在说过去的事情，但用了个is，所以要改成was 这个错错每次改错题目都有，所以看到错的句子有动词，先看上下，有没有时态问题（2）主谓不一致
they was doing …… 这样的错误，找不出么，6级也别考了（3）非谓语动词提前形式的错误
viewed……，they were doing…… 像这样的情况，viewed就要改成viewing 如果后面是it,前面是ing形式，也要注意的（4）平行结构错误
前面连着2句都是to做什么，to做什么and do什么，这时候就要在这个do前加to 如果是to doing，就要改成to do
以上这些错误在考试中占6-7分左右，大家可以一定要抓住，后面的分数就难拿了 另类错误
（1）易混淆的词
比如：His persistence was awarded when the car finally started 中间的awarded是错误的，应该改成rewarded（2）从上下文来看，应该改动的词 一般发生在名词的身上！比如前面说美国人吃饭的习惯，后面写了chinese，那就要改成American（3）固定词组用错一个，造成意思完全改变
比如：It also takes rise to a blurring of the dis tinction between science and technology 要把takes 改成 gives 这样的难点错误，解决方法是，能改则改，不能改确定哪个词错，骗2个0。5分
总的评注：做改错题一定要具有一双“慧眼”。重要的不是自己会运用一个语法点或知识点，而是能够识别出错误的用法，以审查的眼光去面对每一个改错题。这就需要掌握必要的答题步骤和技巧。答题步骤：
1一般来说，做题时千万不要拿起来就改。先花
一、两分钟从头到尾通读全文，对文章大 致内容有所了解，做到心中有数。
2然后把重点放在有错误项的标题号行，寻找较容易辩认的语法错误，如主谓不一致、时态、语态使用错误、非谓语动词错误等等。
3如果错行中不存在上述明显错误，则应查看是否有词语搭配错误，易混词错误、词性错 误等等细节错误。
4如果错行中既不存在语法错误，也不存在词汇错误，则从整体上查看上下文意思是否连贯，连接词是否使用正确，是否有逻辑混乱的现象，如否定句误用成肯定句造成句意不通等。注意：有时没有错项的行对改错很有帮助。
5找到错误项之后，按要求形式进行改正、删去或增添，并设法找到一个正确项使句子在 语法、语义和逻辑上都成立
第四篇：英语单句改错
单句改错.（下列句子各有一处错误，请改正）

第五篇：大学英语四级单句改错例题解析（最终版）
单句改错例题解析
【例1】Sorry，I haven't got any small changes on me．
【解析】这里的“changes”应改为“change”，因为“change”作“零钱”解时为不可数名词。
【例2】Is the education free in all the countries？
【解析】这里“education”前面的“the”要去掉，因为抽象名词表示泛指意义时不用定冠词。
【例3】Peter is stronger than him．
【解析】在省略句或不完整的从句中，代词的格应跟没有省略、完整时的格一致。这一句完整的结构应该是“Peter is stronger than he is，因此不能用“him”。
【例4】The man bought 20 dozens socks．
【解析】象dozen，hundred，thousand等数量词被大于1的基数
词修饰时，仍用单数形式。所以这里的“dozens”应该改为“dozen”。
【例5】M illion of years ago，there lived a lot of huge animals on the earth．
【解析】“hundreds of”，“thousands of，“millions of等结构中，不可遗漏-s。
【例6】China is still a developed country．
【解析】过去分词作定语表示完成或被动之意，而现在分词作定语则表示进行或主动之意。而中国现在仍然是一个发展中国家，因此应把“developed”改为“developing”。
【例7】What a ashamed thing to do！
【解析】“ashamed”是“感觉羞耻的”，通常很少用在形容词前面作定语，一般只作表语，而“shameful”是“可耻的”，通常用在形容词前面作定语。所以该句的ashamed应该改为shameful。
【例8】We object to organize such an activity．
【解析】某些带有“to”的动词词组里的“to”是介词，而不是不定式符号，因此后面应跟名词、名词词组，如果后面是动词，就应把该动词变成动名词或与它相应的名词，这类词组有be used to，oppose ／object to，be accustomed to，relate to，look forward to，等。
【例9】Of all the sports，I like swimming mostly．
【解析】对，一般说来，实意动词都是由副词来修饰的，但有时也要看修饰动词的副词与它修饰的动词是否合意，如这句话里的 mostly就与swim不合意了，因为mostly是“主要地”，“大部分地”，所以应该改为most（“最”）才合整句之意：在所有运动中，我最喜欢游泳。
【例10】No matter who comes to work in our company is welcome．
【解析】“no matter who”只能引导让步状语从句，不能引导名词性从句。因此，此句应改为whoever（＝anyone who．．．）。
【例11】The jury found the defendant guiltily．
【解析】这里的“有罪”是修饰宾语“the defendant”，而并非谓语“found”，因此要用“有罪”的形容词形式“guilty”，而不是副词形式“guiltily”。
【例12】Everybody should be given the chance to reach their goals ／ aims．
【解析】要表达“达到目标”应该用动词achieve，而不是reach。【例13】He has so many skills，which surprise me so much．
【解析】这里引导定语从句的which前有一个逗号，表示这是一个非限制性定语从句。从这句话看，这里的which指前面整个句子，而不只是修饰它前面的skills，所以它后面的动词surprise要加－s。
【例14】The accident resulted from three deaths．
【解析】“result from”意为“是„„的结果，由„„而产生”，而“result in”意为“导致„„结果，结果造成”，而这句话的意思明显是“这一场事故造成三人死亡”，因此应把“result from”改为“result in”。
【例15】The United Nations are a world organization for peace．
【解析】“The United Nations”（联合国）和“the United States”（美国）等虽然形式上是复数，但它们是表示单个机构或国家，因此，如果是现在时，它们后面的动词要用第三人称单数形式。
【例16】More than one person have applied for the job．
【解析】主语由more than one．．．或many a构成，谓语要用单数形式。所以这里的have应改为has。
【例17】Anyone to Greece will see many sites about which they have read． 【解析】Anyone是单数的指称，而they是复数的指称，前后不一致，因此应把they必为he ／she，或者把anyone改为travelers或people。
【例18】Such mistakes can avoid if you are careful．
【解析】当谓语主语是谓语动词动作的承受者时，谓语动词必须用被动语态。所以这里的avoid应改为be avoided。
【例19】If they were careless，they would have lost the good chance．
【解析】在非真实条件句中，表示与过去事实相反，if从句的谓语动词必须用过去完成时形式had done。
【例20】He insisted that we discussed the matter at the meeting．
【解析】在suggest，order，demand，propose，request，insist，ad-vise，require等动词后的宾语从句，谓语动词用虚拟语气“（should）＋ 原形动词”。
【例21】Frightened by the huge explosion outside his window，his head dived under the covers．
【解析】该句中的分词短语Frightened by the huge explosion outside his window的逻辑主语不是the boy's head，而是the boy，因此应把his head改为the boy。
【例22】People of many difference nationalities together on the same block．
【解析】“together”并非动词，不能作谓语，因此根据句子的意思，必须加上谓语live。
【例23】Having not got his letter for a long time，I didn't know what had happened to him．
【解析】分词的否定结构为not ＋分词，所以这里的having not应该改为not having。
【例24】Only then I knew I was wrong．
【解析】在以only，often，many a time，never，seldom，等为首的句型中，要形成部分倒装。所以该句应该改为Only then did I know I was wrong。
【例25】Are you going aboard next year？
【解析】“aboard”意为“上船（车、飞机）”，而“abroad”则为“出国，到另一个国家”，该句的意思明显应为“你明年出国吗？”，所以应把 aboard改为abroad。
