英语从句总让不少东谈主头疼:联结词混用、语序倒置、时态芜杂……
其实掌持规则就能冲突!
本文系统整理主语、宾语等 5 大从句的中枢常识点与使用章程,从界说到用法层层拆解,还配套专项熟谙实时自在。随着学、对着练,从句难点随和攻克!
一、主语从句
中枢常识点
界说:在句中充任主语因素的从句,实质尽头于名词,恢复 “什么事 / 什么情况”。
伸开剩余97%联结词:
that(无现实谈理,不行不详)
whether(表 “是否”)
what/when/where/why/how 等疑问词(表具体疑问含义)
that(无现实谈理,不行不详)
whether(表 “是否”)
what/when/where/why/how 等疑问词(表具体疑问含义)
句式秉性:径直位于句首时可能显为德不终,常用 “it 作花样主语 + 从句后置” 的结构。
使用章程
语序要求:从句必须用诠释语序(主语在前,谓语在后),不行用疑问语序。
造作:What is he doing is unclear.
正确:What he is doing is unclear.(他在作念什么还不明晰。)
花样主语用法:当从句较永劫,用 “it + 形容词 / 名词 + that/wh - 从句” 结构,it 无现实谈理。
例:It’s necessary that we practice English daily.(咱们每天熟谙英语是必要的。)
联结词选拔:
表详情诠释用 that;
表 “是否” 用 whether(不行用 if);
表具体疑问用对应 wh - 词。
表详情诠释用 that;
表 “是否” 用 whether(不行用 if);
表具体疑问用对应 wh - 词。
例:Whether she will attend the meeting is unknown.(她是否参会还不明晰。)
二、宾语从句
中枢常识点
界说:在句中充任宾语因素的从句,常位于及物动词、介词或某些形容词(如 sure/glad)后。
三大中枢考点:联结词选拔、从句语序、主从句时态呼应。
联结词分类:
that(率领诠释句,可不详)
whether/if(率领一般疑问句,表 “是否”)
wh - 疑问词(率领极度疑问句)
that(率领诠释句,可不详)
whether/if(率领一般疑问句,表 “是否”)
wh - 疑问词(率领极度疑问句)
使用章程
语序章程:不管主句是诠释句如故疑问句,从句一律用诠释语序。
造作:I don’t know where is he.
正确:I don’t know where he is.(我不知谈他在那处。)
时态呼应:
主句为一般当今时,从句可字据现实用放纵时态。例:She says she will go tomorrow.(她说她未来要走。)
主句为一般昔日时,从句需用相应昔日时态(客不雅真谛仍用一般当今时)。例:He told me the moon goes around the earth.(他告诉我月亮绕地球转。)

极度预防:
介词后表 “是否” 只用 whether,不必 if。例:I’m worried about whether he can arrive on time.(我惦记他能否准时到。)
主句谓语为 think/believe/suppose 等时,从句狡赖转机至主句。例:I don’t think he is wrong.(我合计他没错。)
