从句在复习从句时,特别要理清时态在从句中的用法,如状语从句(这里主要谈时间状语从句和条件状语从句)时态的用法是,当主句是一般现在时、一般将来时、祈使句时,从句要用现在时。当主句是过去时时,从句则要用过去时态。如:I won't take part in the party if I'm not invited.When the weather is fine,many families go out for a walk.All the students went out when the bell rang.而since引导的从句比较特殊,它的主句一般用现在完成时或一般现在时,从句则用一般过去时。 形容词的用法(1)形容词在句中作定语, 表语, 宾语补足语。例如:Our country is a beautiful country.(作定语)The fish went bad.(作表语)We keep our classroom clean and tidy.(作宾语补足语)(2)形容词修饰something, anything, nothing, everything等不定代词时,形容词放在名词后面。I have something important to tell you.Is there anything interesting in the film.(3)用and 或or 连接起来的两个形容词作定语时一般把它们放在人人好公,则天下太平;人人营私,则天下大乱。 副词的用法1.时间副词时间副词通常用来表示动作的时间。常见的时间副词有:now today, tomorrow, yesterday, before,late, early, never, seldom, sometimes, often, usually, always等。例如:He often comes to school late.He is never been to Beijing.2.地点副词地点副词通常用来表示动作发生的地点。常见的地点副词有:here, there, inside, outside, home,upstairs, downstairs, anywhere, e 语法一致的原则1.以单数名词或代词,动词不定式短语作主语时,谓语动词要用单数;主语为复数时,谓语用复数,例如:He goes to school early every morning.The children are playing outside.To work hard is necessary for a student.2.由and或bothand连接的并列成分作主语时,谓语动词用复数。例如:Both he and I are right.Mr Black and Mrs Black have a son called Tom.但并列主语如果指的是同一人,同一事物或同一概念,谓语动词用单数。 短语动词的分类1.动词+介词常见的有look for, look after, ask for, laugh at, hear of 等。这类短语动词的宾语只能放在介词后。如:Dont laugh at others.Tom asked his parents for a bike.2.动词+副词人人好公,则天下太平;人人营私,则天下大乱。刘鹗常见的有give up, pick up, think over, find out, hand in,等。这类短语动词的宾语如果是名词,既可放在副词前边,又可放在副词后边;宾语如果是人称代词或反身代词,则要放在副词前边。如:Youll hand in your homework tomorrow.
