感叹句
一、知识结构
二、知识点及考点分析
1.定义:感叹句是用来表达人的特殊情感的句子,可以表达人的喜、怒、哀、乐等强烈情感。感叹句可以是一个单词、一个短语,也可以是由what或how引导的句子,句末常用“!”。
2.感叹句句子结构分类:
what引导的感叹句
①What+a/an+名词单数形式+(主语+谓语)!
What a / an 常用来修饰单数可数名词,若其前面的形容词为元音开头,则用an;若其前面的形容词为辅音开头,则用a。
如:What an interesting story it is)!
What a lovely boy he is)!
②What+名词复数形式+(主语+谓语)!
如:What kind women they are!
③What+不可数名词+(主语+谓语)!
如:What nice music it is!
补充:
①what引导的感叹句主语和谓语通常可以省略;
②What常用来修饰复数可数名词和不可数名词。但有些不可数名词,如 rain, surprise, breakfast, lunch 等,当前面有形容词修饰,使抽象名词具体化时,则要用What a/an。
如:What a heavy rain it is)!
③★★★what引导的感叹句常与fun有关的句型放在一起考,属于感叹句易错点:
it's great fun to do sth.
做某事真的很有趣(这里的fun是不可数名词,表示有趣的事)
改为感叹句:What great fun it is to do sth.!
如:What great fun it is to play with dogs!
have fun doing sth. 做某事很开心
改为感叹句:What great fun we have playing with dogs!
tips:陈述句转化为感叹句只改变语序再加上对应的感叹句引导词what/how ,并不改变句子中原有的语法/句型功能。由此点我们可以很好区分两个带fun的感叹句用法。
how引导的感叹句
①How+形容词/副词+主语+谓语!
如:How hard the worker are working!
注意:
当how修饰动词时,动词不跟着感叹词提到主语之前。 如:How the runner runs!
what与how引导的感叹句,一般情况下可以相互转换,转换后意义不变。
如:What a clever girl she is!=How clever the girl is!
②How+形容词+a/an+可数名词单数形式+主语+谓语!
如:How interesting a book it is!
③How+主语+谓语!
如: How time flies!
关于感叹句引导词how和what的选择
第一步:找出句子主语和谓语
第二步:划掉主语和谓语
剩下为名词或名词词组 what
第三步:分析剩下的句子成分
剩下为形容词或副词 how
例子:________ difficult homework we had yesterday!
③ ①②
①找出主语谓语we had
②划掉主语谓语 we had
③剩余成分为名词词组difficult homework,故选择what;且homework为不可数名词,所以这个句子写为What difficult homework we had yesterday!

反义疑问句
一、知识结构
二、知识点及考点分析
1.定义:反意疑问句是提出情况或看法,问对方是否同意的句子。一般由陈述部分和反意疑问部分构成。
2.改写原则:前肯后否,前否后肯
①You can do it, can’t you
②They are not very late for the meeting, are they
3.具体考点:
反意疑问部分主语及谓语的确定
反意疑问部分主语与谓语,应根据陈述部分的主语和谓语进行选择,但是需要注意一些特殊的情况。而且,反意疑问部分的主语一般要用人称代词(一般不会用人名等),而动词若为否定形式则通常用缩写表达,且动词的形式及时态等必须保持一致。
①He has supper at home every week, doesn’t he 不能用hasn’t he )
②They have known the matter, haven’t they 不能用don’t they )
③They will go to school soon, won’t they 不能用don’t they 或 aren’t they )
④He works very hard, doesn’t he 不能用didn’t he 或won’t he )
情况分类:
①陈述部分带有little, few, never, hardly, seldom,nothing,nobody,none等否定意义的词时,问句部分用肯定式。
如:He never tells lies, does he 不用doesn’t he )
注意:当陈述部分谓语动词是含有un-, im-, in-, dis-等表否定意义的前缀的词时,陈述部分要视为肯定含义,反意疑问部分还是要用否定形式。
如:He dislikes playing football,doesn’t he
②陈述部分是there be结构时,用be there即可.
如:There is going to be a sports meeting next Wednesday, isn’t there
③当陈述部分的主语为指物的不定代词nothing,everything,something,anything等时,反义疑问主语部分用it进行指代。
如:Something is wrong with my phone,isn’t it
④当陈述部分的主语为指人的不定代词nobody,everybody,somebody,anybody等时,反义疑问主语部分可用he或they指代,但是不能用it进行指代。
如:Somebody wants to play with you,doesn’t he/they
⑤当陈述部分的主语为指示代词this/that时,反意疑问部分的主语应用单数形式it;若主语为指示代词these/those时,反意疑问部分的主语应用复数形式they。
如:This is necessary, isn’t it
These are your classmates Tommy and Jackie, aren’t they
⑥当陈述部分的动词是has/had/have时,我们需要进行判断具体含义及用法后才能确定反义疑问句怎么改写:
has/had/have表示“有”时,反义疑问部分可以用has/had/have或者does/did/do;
如: He has a new watch,hasn’t he/doesn’t he
has/had/have to表示半情态动词“不得不”时,反义疑问部分应用does/did/do;
如: He has to finish homework,doesn’t he
has/had/have to表示实义动词“吃,喝,玩等”时,反义疑问部分应用does/did/do;
如:They have a nice dinner,don’t they
had better表示“最好”时,反义疑问部分用had;
如:They had better stop laughing,hadn’t they
has/had/have在现在完成时中,反义疑问部分应用has/had/have
如:He has been to Shanghai,hasn’t he
★★★拓展:
1.'s是is还是has的辨析:has只有表示现在完成时的助动词时,才可以缩写为's。所以,我们可以得出:'s后面如果不是过去分词,那么一定是is,而不是has。
如果's后面是过去分词,我们还要区分主被动,如果是表达主动意,那么's是has的缩写,如果表达的是被动意,那么仍然是is的缩写。
eg. He's already back to China, isn't he
He's already been back to China, hasn't he
He's always made to do a lot of housework, isn't he
2.have/has是助动词还是行为动词:如果have/has表示的是助动词,那么后面要有过去分词;如果后面没有过去分词,那么have/has就是行为动词。
eg. He has gone to Hainan, hasn't he
He has a lot of things to do, doesn't he
⑦ 当陈述部分含有need时,如果need作实义动词,则反意疑问部分应用does/did/do,如果need作情态动词,则反意疑问部分应用need。
如:We need to have a rest,don’t we
We need have a rest,needn’t we
⑧当陈述部分出现I am时,反意疑问部分应用aren'tI。
如:I am right,aren’t I
⑨反义疑问句与祈使句结合:
1)肯定祈使句的反意疑问句反问部分用will you或won't you;
2)否定祈使句的反意疑问句反问部分只用will you;
3)以let's开头的祈使句反意疑问句反问部分用shall we;
<特别注意> 只有以let's开头的祈使句的反意疑问句的反问部分才用shall we,而let us 开头的祈使句的反意疑问句的反问部分应为will you或won't you。
如:Don't be late again, will you
Let's turn on the TV, shall we
Please open the door, will/ won't you
Let us have a try,will you
⑩当陈述部分含有情态动词must时,有下列两种情况:
情态动词must表示“必须”时,疑问部分用mustn’t。
如:I must answer the question, mustn’t I
但若表推测这层含义时,不能用must,而要根据陈述部分的不定式结构(即must之后的动词)以及含义采用相应的动词形式。
如:They must have watched the movie last week, didn’t they
He must be in the library, isn’t he
陈述部分用used to +主语时,问句部分用didn’t /usedn’t +主语形式。
如:She used to live in this countryside, didn’t she /usedn’t she
当陈述部分为主从复合句,且反意疑问句的陈述部分为非第一人称主语+ thinkbelieve, suppose, consider,said,told, reported, asked) + that从句时,问句部分的动词和主语与陈述部分的主句动词和主语保持一致。
如:They all think that English is very important, don’t they 不用isn’t it )
注意:若主句的主语是第一人称I/we,其谓语动词又是 think/suppose/believe等时,反意疑问部分的主语和谓语一般应与从句一致。(特别要注意否定转移)
如: I don't think they are good parents,are they
4.反义疑问句回答原则:
①去掉句子中否定词
②将句子变为一般疑问句
③根据实际情况作答,肯定回答用yes,否定回答用no,特别注意前后形式需一致
如:Yes, he isn’t./No,he is 这样写是错的,yes后必须用肯定,no后必须用否定。

二、考点及知识点分析
1.定义:情态动词是表示情态意义的动词,他表示说话人的语气和情态,它不能单独作谓语,必须与实义动词一起构成谓语,情态动词没有人称和数的变化,过去式通常表示更客气、更委婉。
2.情态动词有四个特征:
①不能单独做谓语,必须与其他动词一起构成谓语;
②没有人称和数的变化;
③情态动词后必须跟动词原形;
④具有助动词功能。
3.情态动词基本含义:

如:We must finish homework.
have to表客观需要,意为“不得不”。
如:We have to stay at home,because it’s raining outside.
②maybe与may be
may 为情态动词后接动词原形,may be一般位于句子中;

如:He may be tired.
Maybe he is tired.
③can与be able to
can只有现在和过去时(could),且can强调自身已具有的能力

You mustn’t go out.
三、情态动词具体用法分析:

e.g.Could you help me with my homework
3.may的用法:
①表示请求、许可,比can正式,语气更委婉。
e.g.May I use your dictionary
②表示推测,意为“可能,或许”,一般表示可能性不是很大,用于肯定句中。

④表示对某人的一种希望、祝愿,常可译为“祝愿、祝福某人...”。

The door needs painting. = The door needs to be painted.
6.shall的用法:shall表示征求对方意见(一般用于第一、三人称)。
e.g.Shall we go shopping 回答:Yes, please./All right./No, thank you.
7.should的用法:意为“应该”,表示劝告、建议、或表达某人的义务、责任等。
