Im the best student in my class.不规则变化的形容词、副词的比较等级要记牢。 He plays the piano worst. 动词不定式 跟动词不定式作宾语的常用动词要记牢。如：agree (同意)； offer (提出)； intend， plan (打算，计划)； demand， ask (要求)； promise (答应)； help (帮忙)； prepare (准备)； decide (决定)； refuse (拒绝)；dare (敢于)； choose (选择)； wish，hope，want， expect ,would like (希望，想要)； fail ；（不能；忘记）； pretend (假装)； manage (设法)； determine （决心）。 记忆口诀：同意提出做计划， 要求答应来帮忙。 准备决定遭拒绝， 敢于选择有希望。 不能做到莫假装， 设法做成决心坚。 He would like to go with you.要注意区分某些动词跟动词不定式和动名词所表达的不同意义，如 stop doing 和 stop to do 的区别。 既能接不定式，又能接动词-ing 形式，但意思不同的动词或词组： 即“四记”“力争”“不、后悔”。四“记”指“记得、记住（remember）”；“忘记（forget）”“计划、打算（mean）”；“继续（go on)”；力争指“try”；“不”“后悔”指stop与regret。 He was too tired and stopped to have a rest.一般将来时 要注意一般将来时的构成：be going to do 和 will do.

I have to .含有if 引导的条件状语从句的主从复合句。在使用含有if 引导的条件状语从句的主从复合句时，要注意时态问题，记住：当主句是一般将来时或是含有情态动词的句子或祈使句时，if 从句用一般现在时。Ill help you if you tell me. / If you work hard, you may do better. / If you want to open the door, pree the red button. 重点句型：How often 引导的特殊疑问句及其答语 How often do you exercise?
