1、一否定句1，句子中有联系动词be或情态动词can ，may ，must或助动词will， have， had等词的，应在其后加not.*句中有some , already的，将其变为any, yet 如：There are some people in the garden.-There are not(或arent) any people in the garden. We have already learned English for three years. -We have not (或havent) learned English for three years yet.*alre
2、ady变否定用yet，同时一般放句后。注意have是助动词,还是实义动词。如果是实义动词，要用助动词do的否定式。例：She has supper at six in the evening.-She does not have supper at six in the evening. 2，句子中的谓语动词为实义动词时，则在动词前加dont(doesnt, didnt), 原来的动词恢复原形(分词除外)。这类句子经常考的谓语动词是have和do 。应掌握以下技巧：如：She does (did) her homework everyday(yesterday).-She doesnt( di
3、dnt) do her homework everyday (yesterday).注意：在上句中，原谓语动词(即，实意动词does)前加否定助动词doesnt, 原谓语动词does 变为原形 doShe has (had) a meeting today (yesterday).-She doesnt (didnt) have a meeting today (yesterday). 注意：这里的has或 had 要变为原形have3，had better句型是考试的重点内容之一。它常与主语缩写，如youd ,这种缩写只要看后面有没有better, 即为had, 切忌误认为wouldhad
4、better句型意思为“最好-， 还是-好”，常有告诫、劝告、催促之意，其后接不带to 的不定式，即动词原形。它的否定形式， 一定要把not放在better后面。*had better +动词原形-（肯定式）had better not +动词原形-（否定式）如：Youd better catch a bus.你最好赶得上车子（赶快啊！）Youd better not take these seats.你还是不要做这些位置（座位）此句型的反义疑问句是：Youd better do it now, hadnt you?二祈使句改否定句在前面直接加Dont，而不要管祈使句是以什么动词开始。如：Lo
5、ok out of the window.-Dont look out of the window.考试中常出现以do, have, be开头的祈使句变为否定句。改写这样的句子，应在do (或have和 be) 前加助动词dont， 切忌在do (have, be) 后面直接加not如：Do it after class.-Dont do it after class.三复合句改否定句1，复合句改否定句应掌握think、believe和 feel这三个主句谓语动词后接宾语从句时整个句子的否定形式。这类句子改为否定句时，要对上述主句谓语动词进行否定，但否定意思转移到后面的宾语从句。如：I thi
6、nk he will go there tomorrow.- I dont think he will go there tomorrow. 汉语的意思是“我想他明天不会去那里”，千万不要译“我不想他明天去那里”。更不要把英语句子改成 I think he wont（*严重错误） go there tomorrow.大错特错。2，含有both词语的句子改否定句陈述句含有both+名词或者both of +名词或代词宾格作主语时，改写否定句要用neither 替代both，注意把谓语动词复数形式改写为单数形式。如：Both of them learn English in that school
7、.- Neither of them learns English in that school.句中含有 both A and B改否定句时，要将其改为 neither A nor B, 其谓语动词根据nor后面的名词的数做相应变化。both A and B变否定 neither A nor B如：Both Mary and Jim are students.- Neither Mary nor Jim is a student.四陈述句改写成一般疑问句除遵循be、 will、 情态动词（can、 may、 must）提前以及实义动词前加do (does, did) 以外，还要注意以下技巧：
8、1.陈述句有some, something的，应改为any, anything 。*但是，some与其它词构成的固定搭配不要变化，如：do some shopping/ cooking/ listening/ washing/ reading等。例：There is some oil on the plate.- Is there any oil on the plate?Alice does some reading every night.- Does Alice do some reading every night?2,陈述句主语为第三人称单数 时，且谓语动词是has 或had（不表示
9、“有”的含义，而属其它含义时），或者谓语动词是does或did （表示“做，干”的含义），则句前需要加助动词does (did) 构成一般疑问句，并且实义动词应变为原形 have、do 或者其他动词原形 。如：He usually has lunch at 11:30.- Does he usually have lunch at 11:30 ?Mary sang a beautiful song in the last party.- Did Mary sing the beautiful song in the last party?五改写成特殊疑问句。特殊疑问句由“疑问句 + 一般疑问句
10、”构成，改写这种句子应把握两个关键，一是选准疑问词；二是将疑问词后的句子变成一般疑问句。注意以下技巧：1. 对于时间划线用what time （具体时间，如at 9:00）how long (一段时间，如since 2000, for two days) how often（ 频率时间，如once a year） how soon( 将来时间，如in a month)。如：We have lived here since 1986.-How long have you lived here?2, 对于职业划线用what.如：Henry is an English teacher.-What i
11、s Henry?3, 对距离划线用how far，对长度划线用how long，注意二者不能互换。如：He travelled nearly ten thousand kilometers. -How far did he travel ?The Yellow River is 5464 kilometres long. -How long is the Yellow River?4, 对数量划线用how many （后面跟可数名词复数），how much（后面可跟不可数名词，也可单独作句子成份）如：There are four persons in our office.-How many
12、persons are there in your office?This book is six dollars.-How much is this book?5, 对其它部分划线的见以下的例子：对日期提问：Its December 31 today.-Whats the date today?对颜色提问：The tree is green.-What colour is the tree?对年龄提问：My nephew is about four.-How old is your nephew?对姓名提问：My name is Helen.-Whats your name?对事物、事情提问
13、：They are going to visit the Great wall next week.-What are they going to do next week?对班级提问：Were in Class One, Grade Three.-What class(grade) are you in?或Which class(或grade) are you in ?对重量提问：I want a kilo of meat.-How much meat do you want?对地点提问：He works in a school.-Where does he work?对星期提问：Its W
14、ednesday today.-What day is it today?对方式提问：I usually come to school on foot.-How do you usually come to school?对原因提问：My face turned red because I told my teacher a lie.-Why did your face turn red?六.改写成反意疑问句。反意疑问句由“陈述句 + 简略问句”构成，当陈述句为肯定句时，简略问句为否定形式，反之亦然。关键抓住三点：1）是简略问句的动词应与陈述句的动词相对应，并采用一般疑问句的助动词或情态动词的
15、形式2）是简略问句的主语一般用代词，不再重复陈述句的名词3）是陈述句中如存在某些具有否定意义的词（ hardly, few、little、seldom等），简略问句应为肯定形式。这是改写反意疑问句的一般技巧。另外除需熟悉一般情况外，更应掌握特殊情况。特殊情况 ：简单句的附加简略问句1)陈述句部分为there be结构，附加的简略问句为be (not) there?例：There are not any people living here , is there? 绝不能因为any people为主语而用are they等。2)陈述句为I am ,附加的简略问句为arent I .例：I m taller than you, arent I. 不能用am not I .这是特殊用法。3)陈述句主语为everybody , everyone , somebody
