2. Mr Smith said, “John is a good student.”

→Mr Smith said that John was a good student.

1. Mary often says, “I want to be a doctor when I grow up.”

→Mary often says that she wants to be a doctor when she grows up.

2. -----time, he will make a first-class tennis player.

A. Having given B. To give C. Giving D. Given

该题的三个关键点：主语he，谓语动作make，非谓语动作give：he与give之间同样是被动关系，而ABC均为主动，所以选D。该题如果增加难度，可以加入一个迷惑选项：被动完成式having been given，此项也不可选，因为完成式必须表示动作已发生过;本题中动作只是一种假设，尚未发生。

本文将对高中英语语法专项复习之情态动词进行详细介绍，希望对大家的英语学习有所帮助：

情态动词的语法特征

1) 情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。

2) 情态动词 除ought 和have 外，后面只能接不带to 的不定式。

3) 情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。

4) 情态动词没有非谓语形式，即没有不定式，分词，等形式。

比较can 和be able to

1)cancould 表示能力;可能 (过去时用could),

只用于现在式和过去式(could)。be able to可以用于各种时态。

They will be able to tell you the news soon. 他很快就能告诉你消息了。

2)只用be able to

a. 位于助动词后。

b. 情态动词后。

c. 表示过去某时刻动作时。

d. 用于句首表示条件。

e. 表示成功地做了某事时，只能用was/were able to， 不能用could。

He was able to flee Europe before the war broke out.

= He managed to flee Europe before the war broke out.

注意：could不表示时态

1)提出委婉的请求，(注意在回答中不可用could)。

--- Could I have the television on?

--- Yes, you can. / No, you can't.

2)在否定，疑问句中表示推测或怀疑。

He couldn't be a bad man.

他不大可能是坏人。

比较may和might

1) 表示允许或请求;表示没有把握的推测;may 放在句首，表示祝愿。

May God bless you!

He might be at home.

注意： might 表示推测时，不表示时态。只是可能性比may 小。

2) 成语： may/might as well，后面接不带to 的不定式，意为"不妨"。

If that is the case, we may as well try.

典型例题

Peter ___come with us tonight, but he isn't very sure yet.

A. mustB. mayC. canD. will

答案B. 表可能性只能用may.此句意可从后半句推出。

比较have to和must

1)两词都是'必须'的意思，have to 表示客观的需要， must 表示说话人主观上的看法，既主观上的必要。

My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事)

He said that they must work hard. 他说他们必须努力工作。(主观上要做这件事)

2)have to有人称、数、时态的变化，而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。

He had to look after his sister yesterday.

3) 在否定结构中： don't have to表示"不必"

mustn't表示"禁止"，

You don't have to tell him about it.你不一定要把此事告诉他。

You mustn't tell him about it.你一定不要把这件事告诉他。

must表示推测

1) must用在肯定句中表示较有把握的推测，意为"一定"。

2) must表对现在的状态或现在正发生的事情的推测时， must 后面通常接系动词be 的原形或行为动词的进行式。

You have worked hard all day.You must be tired.你辛苦干一整天，一定累了。(对现在情况的推测判断)

He must be working in his office. 他一定在办公室工作呢。

比较：

He must be staying there.

他现在肯定呆在那里。

He must stay there.

他必须呆在那。

3) must 表示对已发生的事情的推测时，must 要接完成式。

I didn't hear the phone. I must have been asleep.我刚才没有听到电话，我想必是睡着了。

4) must表示对过去某时正发生的事情的推测，must 后面要接不定式的完成进行式。

---Why didn't you answer my phone call?

---Well, I must have been sleeping, so I didn't hear it.

5) 否定推测用can't。

If Tom didn't leave here until five o'clock, he can't be home yet.如果汤姆五点才离开这儿，他此时一定还未到家。

表示推测的用法

can, could, may, might, must 皆可表示推测，其用法如下：

1)情态动词+动词原形。

表示对现在或将来的情况的推测，此时动词通常为系动词。

I don't know where she is, she may be in Wuhan.

2)情态动词+动词现在进行时。

表示对现在或将来正在进行的情况进行推测。

At this moment, our teacher must be correcting our exam papers.

这时，我们老师想必在批改试卷。

3)情态动词+动词完成时。

表示对过去情况的推测。

We would have finished this work by the end of next December.

明年十二月底前我们很可能已完成这项工作了。

The road is wet. It must have rained last night.

地是湿的，昨天晚上一定下雨了。

4)情态动词+动词的现在完成进行时。

表示对过去正在发生事情的推测。

Your mother must have been looking for you.

你妈妈一定一直在找你。

5)推测的否定形式，疑问形式用can't, couldn't表示。

Mike can't have found his car, for he came to work by bus this morning.

迈克一定还没有找回他的车，因为早上他是坐公共汽车来上班的。

注意：could, might表示推测时不表示时态，其推测的程度不如can, may。

情态动词+have+过去分词

1) may(might) have + done sth, can (could) have + done sth表示过去，推测过去时间里可能发生的事情。

Philip may (might) have been hurt seriously in the car accident.

Philip can (could) have been hurt seriously in the car accident.

2)must have +done sth，对过去时间里可能发生的事情的推测，语气较强，具有"肯定"，"谅必"的意思。

---Linda has gone to work, but her bicycle is still here.

---She must have gone by bus.

3) ought to have done sth, should have done sth

本应该做某事，而事实上并没有做。否定句表示"不该做某事而做了"。

You ought to (should) have been more careful in this experiment.

He ought not to have thrown the old clothes away.(事实上已扔了。)

ought to 在语气上比should 要强。

4) needn't have done sth本没必要做某事

I dressed very warmly for the trip, but Ineedn't have done so. The weather was hot.

5) would like to have done sth本打算做某事

I would like to have read the article, but I was very busy then.

should和ought to

should 和ought to 都为"应该"的意思，可用于各种人称。

---Ought he to go?

---Yes. I think he ought to.

表示要求，命令时，语气由 should(应该)、had better最好)、must(必须)渐强。

had better表示最好

had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。

had better do sth

had better not do sth

It is pretty cold. You'd better put on my coat.

She'd better not play with the dog.

had better have done sth表示与事实相反的结果，意为"本来最好"。

You had better have come earlier.

would rather表示"宁愿"

would rather do

would rather not do

would rather… than…宁愿……而不愿。

还有would sooner, had rather, had sooner都表示"宁愿"、"宁可"的意思。

If I have a choice, I had sooner not continue my studies at this school.

I would rather stay here than go home. = I would stay here rather than go home.

高中英语语法专项复习之独立主格

本文将对高中英语语法专项复习之独立主格进行详细介绍，希望对大家的英语学习有所帮助：

(一)： 独立主格结构的构成：

名词(代词)+现在分词、过去分词;

名词(代词)+形容词;

名词(代词)+副词;

名词(代词)+不定式;

名词(代词) +介词短语构成。

分词使我们中国学生最头疼的语法点知识。很多学生读了研究生后依然搞不清楚现在分词和过去分词。其实，只要适当的加以分类和记忆，便能迅速地理情头绪，并彻底掌握它。

1. -----such a good chance, he planed to learn more.

A. To be given B. Having been given C. Having given D. Giving

该题有三个关键点：主语he，谓语动作plan，非谓语动作give;he与give之间很显然是被动关系，所以排除表主动的现在分词C和D;give这个动作明显在谓语动作plan之前，所以选择完成式B

对于从句的把握，不仅对语法题目意义重大，对写作也大有裨益。要弄明白名词性从句、状语从句、定语从句三者的区别和联系，要了解各自的引导词以及引导的句子种类，从本质上把握它们。

1. A modern city has been set up in____ was a wasteland ten years ago.(2004 天津)

A. what B. which

C .that D. where

此题解答时，易把汉语的习惯移植进去：十年前曾是一片废墟的地方，从而误选D。本题中，空格及空格后面的部分共同做介词in的宾语。而在这个宾语从句中，空格部分又要做主语。毫无疑问，where是副词的性质，从来只能做状语，决不可能做主语。同时本题有没有给定一个供选择的范围，所以排除了which。正确答案是A

2. It is said in the book that Thomas Edison (1847-1931)____the world leading inventor for sixty years.(2004辽宁)

A. would be B. has been

C. had been D. was

此题难度较大，无数考生拜倒在其脚下。错误的原因是：看到for sixty years，再加上前面用了一般现在时的动词is，便以为是现在完成时，所以选择B。殊不知题目中给出的是一段过去的时间(1847-1931)，而一般过去时也可以用以描述过去的一段时间的事实。所以答案是D：爱迪生过去曾经连续60年是世界上发明创造界的领袖。

动词的时态依然是亘古不变的重点。时态的考查也不再局限于过去时，过去完成进行时等也开始出现在考卷上。这一类题目中，理解其所给的语境成为答对题目的关键。另外，试题中还故意设计出了一些陷阱：如经常出现在某一种时态中的时间状语放在另一种时态里。考生极易犯思维定式的错误，所以，务必认真审题也变得非常重要。

1. The crazy fans____ patiently for two hours, and they would wait till the movie star arrived .( 2004重庆)

A were waiting B. had been waiting

C. had waited D. would wait

这道时态题难度不小，从题目中的场景可知，空格处的“等待”动作应发生在“arrived”之前，即过去的过去，所以应用过去完成时;同时“for two hours”这个时间状语告诉我们该句强调的是动作在过去一直持续进行。综合二者，我们选择一个最佳答案：过去完成进行时。答案为：B

2. ----Do you like____ here?

----Oh , yes. The air, the weather, the way of life. Everything is so nice. (2004 全国一)

A. this B. these

C. that D. it

很多同学看到The air, the weather, the way of life，以为这么多东西，当然应该是these了，从而误选了B。此处it指代这些东西，同时对应了Everything。正确答案是D

词法方面，词语的辨析成为现今高考命题的重点，对考生来说也是一大难点。其综合性越来越强，很多题目要根据上下文，反复比较才能做出正确判断。这也提醒我们学习词语时，要关注它的多个意思，同时不要死记硬背，要在具体的语言环境里灵活地学习和掌握。

1. ____ two exams to worry about, I have to work really hard this weekend.(2004 北京)

A. With B. Besides

C. As for D. Because of

本题说的是：因为担心两门考试，这个周末我不得不拼命学习。句意很简单明了，besides“除了”，as for“至于”两个选项很容易排除，因此许多同学根据字面意思选择了错误选项D。错误的原因是because of后边不能接复合宾语，而正确答案A项构成的with独立结构也可表原因。所谓with独立结构是指with+名词(或代词)+分词/不定式/形容词/副词/介词短语
