专题九 复合句
考点梳理
考点1 宾语从句
1.语序:宾语从句的语序应为陈述语序。即:主语+谓语+宾语+其他。
·Can you tell me how many boy students there are in the class?
·Do you know where he works?
2.时态:“主现从不限”,即主句是一般现在时,宾语从句可以根据具体情况使用任何一种时态。
“主过从过”,即主句是一般过去时,宾语从句一般使用过去时间范畴的某种时态。
注意:当宾语从句表示的是客观事实或真理时,其时态不受主句限制,习惯上使用一般现在时。
·She said that there were many books on the desk.
·Our father said that he would buy a new computer next week.
3.否定转移:当主句的谓语动词是think,believe,expect,imagine,guess,suppose等,且宾语从句表示否定意义时,常常将否定词转移到主句中去,从句仍用肯定形式,这种现象叫“否定转移”。
·I don‘t believe they will wait to the last minute.
·I don’t think that he will come.
4.连接词
(1)that在宾语从句中无实际意义,可省略。
·He said (that) he would go to the movies.
(2)连接代词(what, which, who, whose, whom等),在从句中作一定的成分,如:作主语、宾语、定语等。
·I don‘t know what they are going to do.
(3)连接副词(when, where,why, how等),在从句中作状语。
·Please tell me how you go to school.
(4)当宾语从句由一般疑问句变化而来时,连接词用whether或if,表示“是否”;句尾有or not时用whether。
·Could you tell me if/whether it snows in winter in Australia?
考点2 定语从句
