初中英语学期动词不定式(to)的用法

要简单点的,好人,不要出现什么宾语什么动名词之类的,因为老师教我们还没有教语法。要简单点的,没学过语法的人能看得懂的,而且还能学得会的。谢谢了,我的大好人。帮帮我,我那天没学着动词不定式,因为我请假感冒了。如果你让我这点搞懂了我说不定可以得满分呢,就救救我吧,thanks.

七、省to 的动词不定式
  1) 情态动词 ( 除ought 外,ought to):   2) 使役动词 let, have, make:   3) 感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作宾补,省略to。   注意:在被动语态中则to 不能省掉。   I saw him dance.   =He was seen to dance.   The boss made them work the whole night.   =They were made to work the whole night.   4) would rather,had better:   5) Why… / why not…:   6) help 可带to,也可不带to, help sb (to) do sth:   7) but和except:but前是动词do时,后面出现的动词用不带to的动词不定式。   8) 由and, or和than连接的两个不定式,第二个to 可以省去:   9) 通常在discover, imagine, suppose, think, understand等词后,可以省去to be:    He is supposed (to be) nice. 他应该是个好人。   10)but作介词,后接不定式结构时,前面谓语动词部分若含有do的形式时,but后的不定式要省去to,否则要带to。    He wants to do nothing but go out.   He wants to believe anything but to take the medicine.   11)当两个或多个不定时短语由连词and,but或or连接时,后一个或几个不定式符号to常省略。但若表示对比、对照关系时,则不能省略。   He wants to move to France and marry the girl.   The purpose of new technologies is to make life easier,not to make it more difficult.   12)不定式做表语时,一般要带to,但若主语部分中含有do的各种形式时,符号to可省去。   We've missed the last bus.All we could do now is walk home.   举例:   He wants to move to France and marry the girl.   He wants to do nothing but go out.   比较:He wants to do nothing but go out.   He wants to believe anything but to take the medicine.

remember to do sth.记住未做的事
like to do sth喜欢做某事
stop to do sth.停下来做另一件事
decide (not)to sth.=make a decision(not) to do sth.决定做某事 (否定动词不定式)
be willing to do sth。乐意做某事
plan to do sth计划做某事
used to do sth。过去常常做某事
need to do sth需要某人做某事
can't wait to do sth迫不及待做某事
refuse to do sth拒绝做某事
wish (sb)to do sth希望某人做某事
以上常见动词不定式短语,to后跟动原。
初中的话就只有to后跟动原的,初三有to接动词ing形式的。大概是吧。
另外,副词前要省介词to(here,there,home)

根据楼主的情况,那就先简单的记几个句型就可以了。如:want to do sth
decide to do sth.
offer to do sth.
hope to do sth.

tell sb.. to do sth.
ask sb. to do sth.
像上面的这些类似的句型都属于动词不定式的句型。
