3．辨析more than, no more than, more… than, not more than
请翻译下列句子:
1．The speed is more than 80 miles per hour.
2．The villagers were more than glad to help those tourists.
3．All his education added up to no more than one year.
4．There were not more than a hundred people at the meeting.
5．She is more thoughtless than stupid.
Key：1．时速超过了80英里。（more than 多于，超过）
2． 乡亲们很愿意帮助那些游客。（more than 不只是）
3． 他所受的教育加起来不到一年。（no more than 仅仅，只有，少于）
4． 大概不到一百人参加了会议。（not more than 不超过，不多于）
5． 与其说她笨，倒不如说她粗心大意。（ more．．． than 与其说．．．倒不如说．．．）
三、重点句型
1．There did not seem much point in working on my PhD ---- I did not expect to survive that long.
There is no point （in） doing sth. “做某事没有作用或意义”, 类似的句型有: There is no sense （in） doing sth.
例如:
There seems little point protesting; it won’t help.
There was no sense in making a child suffer like that.
2．What if…如果…将会怎样; 即使…又有什么要紧。
例如：
What if he finds out that you have lost her book?
What if…还可以用来表示建议、邀请、要求等。例如：
What if you go instead of me?
3．Experienced editors and reporters make informed decisions about what events to report, how to report them, and why.
What events to report 是“疑问词+不定式”结构，在句中作宾语。此结构中的不定式与前面的疑问代词有动宾关系，但不定式要用主动形式。
例如：
I really don’t know what to write at the moment.
4．The result is a better understanding of the world on all sides, leading to a future world where people from all countries are respected and different views and opinions are tolerated.
Leading to…. 是现在分词短语作状语，表示结果。
例如：
Her father died in 1979, leaving her with four younger sisters.
四、语法复习
（一）动词不定式
动词不定形式：to+动词原形；或者省略to.
没有人称和数量的变化，具有名词、形容词和副词的特征，在句子中作谓语以外的成分。
1．作主语：What does it mean to be a scientist?
2．作宾语：People who listen to Hawking’s lecture find it difficult to understand him.
3．作表语：Nothing in life is to be feared. It is only to be understood.
4．作宾语补足语: He told me to bring some books for you.
5．作定语：The doctor told him he might not have more than twelve months to live.
6．作结果状语：Readers were pleased and surprised to find that a scientist could write about this work in a way that ordinary people could understand.
7．目的状语：In order to get married, I needed a job, and in order to get a job, I needed a PhD.
8．某些固定的形容词搭配用于口语中，例如：Glad to meet you. Sorry to trouble you.
9．和常见的疑问词搭配作动词的宾语，相当于宾语从句（宾语从句的主语和主句的主语要一致）。
例如：
I don’t know what to say/what I should say. Could you tell me when to start/when I should start?
（二）过去分词作定语和表语
过去分词在句子中可以作定语、状语、表语和补足语，通常与句子中的某个名词有逻辑上的被动关系，有时还表示动作的完成或者状态。
1．作定语：单个的过去分词作定语放在名词的前面，过去分词词组作定语放在名词的后面，有时相当于非限制性定语从句。
例如：
a broken glass, the used books, in an organized way, experienced editor
Chen wrote about the efforts to bring stolen cultural relics to China.
I want to wrote about people addicted to drugs/who are addicted to drugs.
过去分词作后置定语时，有时有时态的区别，
例如：
Do you live in the building built last year?
I will live in the building being built now.
The building to be built will be for teaching.
过去分词作定语表示被动的和已经发生的动作；现在分词作定语表示主动和的和正在发生的动作。
例如：
fallen leaves, falling leaves, fading flowers, faded flowers, boiling water, boiled water
1．作表语：表示事物或人所处的状态:
We were all surprised at his arrival.
This cup is broken.
My sister feels very interested in cooking.
过去分词作表语表示主语的状态是由于外界而引起，而现在分词作表语表示主语是动作的发出者，“令人……的”，
例如：
This snake is so frightening that the bravest boys are frightened at it.
He is interested in this interesting game.
This climbing is tiring and they are all tired now.
过去分词作表语表示状态，而被动语态表示动作。
例如：
This cup is broken.
This cup was broken by a careless boy.
He is well educated.
He was well educated in a famous college.

What does a policeman actually do? It is not 3 job to describe. After all, a policeman has a number of jobs in 4 . A policeman often has to control traffic, either 5 foot in the center 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 6 up and down main roads and motorways. A traffic policeman has to help keep the traffic moving, stop 7 motorists and help when there is an accident.
A policeman has to help keep the 8 , too. If there is a fight or some other disturbance, we 9 the police to come and restore order. And they often have to 10 situation at great risk to their own 11 .
We expect the police to solve crimes, of course, so an ordinary policeman, 12 he is not a detective (侦探), will often have to help 13 and arrest criminals.
And 14 do we call when there is an emergency – an air crash, a 15 , a road accident, or a robbery? We call the police. 16 policeman has to be 17 to face any unpleasant emergency that may happen in the 18 world.
The police do an absolutely necessary job, they do it 19 well and I support them, but I do not envy policemen, I do not think that I could 20 do the job of a policeman.

能力拓展
1—5 CADBA 6—10 BCADC 11—15 ADCDB 16—20 DCBAC
1．C 根据下文作者的观点可以排除A、B项，作者非常“欣赏”警察的工作，而不是“羡慕”。
2．A should此处的意思是“应该”，此句的意思是“有一些人认为警察不应该有他们所拥有的权力”。
3．D 根据下文的描述，警察的工作种类很多，又充满危险，所以选an easy。
4．B 根据下文的叙述，警察要做的工作有很多，所以“ a number of jobs in one”。 这里的jobs的意思是“pieces of work, tasks（多种工作，任务）”。
5．A　此处“on foot”为固定词组。
6．B　在motorway上不能步行，只能开车，所以要用driving。
7．C　此处“speeding motorists”指的是超速行驶的机动车辆。选项“drunken”的意思是“喝醉酒的”，警察不可能一下子就判断出来哪个司机是喝醉酒的。
8．A　下文“there is a fight”告诉我们，警察的任务是要维护和平。
9． D此题考察动词及词组的意义。 wait for 意思是“等待某人”；call意思是“打电话”； expect somebody to do something表示“期待某人做某事”；think of意思是“想起，想到”。D项最符合文中的意思“一旦有打架或者骚乱，人们就期待警察出现并维护秩序。”
10．C　面对的情况是需要处理的，所以选择词组deal with；动词treat的意思是“对待、治疗”。
11．A　警察在工作时会有危险，对他们的安全造成威胁。所以此处选safety。
12．D　这里的“although、 even if”都可以引导让步状语从句，但是even if是一种不是事实的假设，而although与主句的关系为转折，此处警察不是侦探，所以选even if。
13．C 此题考察词组的意义区别。look for表示“寻找”；get rid of表示“摆脱，除掉”；question意思是“质问”；sentence作为动词意思是“判处，宣判”。此处的意思是“警察寻找并追捕犯罪分子。
14．D 根据下文的“we call the police”，选择疑问词who，指人。
15．B 根据前文的emergency（紧急情况），可以看出只有选项a fire（火灾）属于“紧急情况”。
16．D 由前文可以知道，当我们面对紧急情况时总是会找警察，所以按照意思顺下来，就应该用so表示“因此，结果 …”。
17．C 根据上文，面对emergency，警察随时随地都要“prepared”。另外，要注意词组“be prepared do to something”。
18．B 　in the modern world：在现代社会里。
19．A “extremely”在此处意思是“非常，极端”，此处是赞扬警察的工作非常好。
20．C 本句的否定前移了。当主句主语为第一人称、动词为think等词时，常用此否定前移结构，翻译成汉语应该是“我认为我不 …”。A、D项都是否定词，与not构成双重否定，意思不对；forever不合此语境。
