学好英语词汇量、语法、句法能力和逻辑思维能力等有密不可分的关系。下面星星乐小编就大家整理一下初二英语下册重点知识点汇总，仅供参考。
重点语法：宾语从句
结构：主语 + 谓语动词 + 宾语从句(主语 + 谓语动词 + 宾语/表语)
例句：----Im good at English. He says. (改为加宾语从句的复合句)
----He says Im good at English.
注意：①主句是一般现在时态，宾语从句的时态不受其影响。
例句：He says Im good at English now.
He says I was good at mathematics when I was young.
②主句是过去时态，宾语从句也要用过去时态。
例句：He said I was good at mathematics when I was young yesterday.
He said I was good at English now yesterday.
③宾语从句是客观真理时永远用一般现在时态。
例句：Our teacher says 24 hours make a day.
Our teacher said the sun gives us so many energy yesterday.
④动词原形不能作主语，必须用其 -ing 形式。
例句：She said helping others changed her life.
重点短语：direct speech 直接引语
reported speech = indirect speech 间接引语
first of all = at first 首先
pass on 传递
be supposed to do sth. 应该做某事
be good at = do well in 在某方面做得好
in good health 身体健康
get over 克服
open up 打开
care for = take care of = look after 照料;照顾
not any more = not any longer = no longer 不再
have a cold 感冒
end-of-year exam 年终考试
get nervous 变得紧张
forget to do sth. 忘记做某事(该事未做)
forget doing sth. 忘记做某事(该事已做)
its + adj. + [for sb.] + to do sth. 做某事[对某人来说](加形容词)
句型结构基本概念
句型结构基本概念：与汉语相似，英语句子是由主语(subject)，谓语动词(verb)，宾语(object)，表语(predicative)，状语(adverbial)，宾语补足语(objectcomplement)等成分组成，按照这些成分的组合方式英语句子可分为五种基本句型。
复合句
复合句(Complex Sentence)由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause)构成。
主句是全句的主体，通常可以独立存在;从句则是一个句子成分，不能独立存在。
从句不能单独成句，但它也有主语部分和谓语部分，就像一个句子一样。所不同在于，从句须由一个关联词(connective)引导。
