The Summary Of Grammar
The attributive clause（定语从句）
定语从句做题步骤
1.判断句子是否为定语从句 2.若句子是定语从句，找到先行词，判断是人还是
物 3.分析句子是否缺少成分，然后选择关系代词或关
系副词 4.介词加which就相当于某些关系副词 5.What 一定不能用于定语从句中
e.g. There goes the bell and class is over. Here you are.
3.表示地点的词置于句首时 e.g. On the ground lay a sick person.
4.直接引语置于句首时 e.g. “Help” shouted the boy.
5.现在分词，过去分词，形容词+系动词+主语 e.g. Gone are the days when women were looked down upon. Present at the meeting was Mr Wang.
That 在名词性从句中不充当任何句子成分，只起连接作用， 引导主语从句时常用it作形式主语；引导宾语从句时，常 被省略。
e.g. That she will refuse the offer seems unlikely.
只用whether不用if的场合
1.引导主语从句且置于句首时 e.g. Whether he will go there or not is not clear.
★现在完成时（对现在造成一定影响，要特别注意for, since引导的时间状语从 句以及第几次做某事）
★过去完成时（过去的过去）
动词的语态
• 用主动表示被动的情况
1.表示主语的某种特征的动词，如read, write, wash, dry, sell, wear… e.g. The coat dries easily.
• Doubt用于否定句或疑问句时，后面的名词 性从句的连接词常用that
• Sure用于肯定句时，后面的名词性从句的 连接词常用that
• Sure用于否定句或疑问句时，后面的名词 性从句的连接词常用whether或if
That 在定语从句和同位语从句中的 区别
• That作为关系代词引导定语从句，在从句中可充 当主语宾语和表语，作宾语时常可被省略
• That引导同位语从句时，起连词作用，不充当任 何成分，一般不能省略也不能与which互换。
动词的时态和语态

★一般过去时 （要特别注意过去某一段时间经常或反复的动作）
★一般将来时 （要特别注意be to表示按计划或安排要做的事，be about to 表 示即将发生的动作）
★现在进行时（要特别注意动词加be动词的情况，它有一种故意如此的意思， e.g. You are stupid.(你很糊涂）You are being stupid.(你在装糊涂）） 有一些词不用于进行时态： 短暂动作类：finish, marry… 感官类：see, hear, smell, taste, feel, seem, sound… 感觉类：hate, like, love, wish… 存在类：be, exist, remain, stay… 占有从属类：have, possess, own, belong… 认知类：understand, know, think, remember…
