从以上的例子来看，我们可以归纳出以下的规则：

1.Verbtobe后面可以直接加not。

例如：

Heisnotagoodteacher.

Marywasnotveryhappywhenshewasyoung.

Theyarenotstrongboys.

Peterisnotcoming.

Johnisnotgoingtowork.

2.助动词后面可以直接加not。

Hehasnotwrittenanyletter.

Theywillnotcome.

Hecannotswim.

Theyshouldnotcryveryoften.

Tomhadnoteatenanythingbeforeyoucame.

Hemaynevereatcakesinthefuture.

Johnhasnotlivedhere.

3.一般句子的动词必须加入do或他的变形。

Hedoesnotsmoke.

Hedidnotgo.

Idonotlovesports.

Youdonotliketoeatfish.

Theydonotswimverywell.

Wedidnotseethatmovie.

在英文中，我们可以用haveto来代替must，以下是haveto的例子：

HehastogotoChicagotomorrow.（他明天应该去芝加哥）

Theyhadtobuythreeticketstogototheconcert.（他们必须买三张票去听音乐会）

Ihavetoworkveryhard.（我必须努力工作）

含有haveto的句子，如要改成否定句子，必须在haveto前面加do或它的变形，请看以下的例子：

Hehastoeatalotoffood.

Hedoesnothavetoeatalotoffood.

Hehadtoleave.

Hedidnothavetoleave.

Ihavetowritethatletter.

Idonothavetowritethatletter.

4.Theycanplayviolinverywell.

5.Mr.Changmustanswerthefollowingquestions.

9.Itrainedheavilylastnight.

10.Ihavelivedhereforthreeyears.

11.Hehastoseehismother.

12.Hehadtostayhereyesterday.

2No,Never和Any的用法

要达成否定的意思,有时我们也可以用no和never这些字，no必须跟一个名词，请看下面的例子：

1.Isawnostudentshere.

2.Therearenolakesinthiscountry.

3.Ihavenomoney.

4.Ihadnochoice.

5.Hehasnofriends.

以上这些例子也可以用not来表示否定的意思，如果用not，则以上的句子应该照下面的方式写；

1.Ididnotseeanystudenthere.

2.Wecannotfindanylakeinthiscountry.

3.Idonothaveanymoney.

4.Ididnothaveanychoice.

5.Hedoesnothaveanyfriends.

除以上not之外，never也可以表达否定的意思，以下都是never的例子，请注意never常用在完成式的句子里：

Ihavenevergonethere.

Hehasneverwrittenanysong.

Theyhaveneverwashedtheirclothes.
