that在引導(dǎo)從句時的省略現(xiàn)象
一、that引導(dǎo)定語從句時,充當關(guān)系代詞.
A.that在定語從句中作賓語時,往往可省略.He is the man(that)I gave the money to.B.that在定語從句中作主語時,不可省略.He'is the man that lives next door.C.that在way,distance后面?？墒÷?I went out the same way(that)I'd got in.
二、that引導(dǎo)名詞性從句時,充當連詞,本身無實際意義.
A.that引導(dǎo)主語從句、同位語從句及表語從句時,正規(guī)語中,通常不可省略.It was known long ago that air has pressure.They all know the fact that Taiwan is part of China.Their suggestion is that should improve their working conditions.B.that在引導(dǎo)賓語從句時,通?？墒÷?We know(that)sound can travel through air.但：1）在介詞后的賓語從句中that常不可省略,且前面往往有個形式賓主it:You may depend on it that they will support your plan.See to it that you are not late again.Except that he speaks too fast,he is an excellent teacher.2)兩個賓語從句連用時,即使省略了第一個that,也不可省略第二個that.I believe(that)you've done your best and that things willimprove.
三、that引導(dǎo)狀語從句時,充當連詞,有時也可省略.
A（結(jié)果狀語從句）The sound is so weak(that)you can't hear it.B(結(jié)果狀語從句)Now(that)I have finished my lessons,I intend to go for a walk.C(賓主從句)We are delighted(that)you can come.D(某些邊際連詞)如：the monent that,the minute that,the instant中省略that.The monent(that)he spoke,we recognized his voice
