that在从句中的用法和表示什么

that可以引导名词性从句、定语从句,其具体用法如下：

一、that引导名词性从句时(即主语从句、宾语从句、表语从句、同位语从句),在从句中无具体含义,只起连接作用,而且在从句中也不作任何句子成分.它所引导的从句的句子结构和意义是完整的,而且从句一般是陈述一个事实.

例如:

①Th来自atshewasabl360问答etocomemadeusveryhappy.

她能来使我们很高兴.

②Thenewsthatourteamhaswonthematchistrue.

我们队赢了这场比赛的消息是真的.

③Thereasonhedidn'tcomewasthathewasill.

他没来的原因是他病了.

当that引导的主语从句或宾引子称岩语从句太长时,常用it作形式主语或宾语而把that从句放在后面.如:

①It婷声洲伯草友纸具外色五iswell—knownthattheea校身张rthisroun半字却合d.

众所周知,地球是圆的.

②基弦动种混帮矿曾喜Wefinditnece刚效少云音争写兰析阶ssarytha在换导族由显由凯合商twepractisespokenEnglisheveryday.

我们发现每举角关假天练习英语口语很有考决从源协赶杆远露必要.

注意：

that引导的主语从句,表语从句以及同位语中,that不能省略.that引导的宾语从句,一般可以省去that,但在下面场照事块写良住们情况中不能省略——

1.在s凯千uggest,o于rder等表示命令、请求、建议等动词后的宾语从句中,不能省；

2.由and或but所连接的两个引导的宾语从句时,第一个从句中的that可以省,第二个从句中的that不能省；

3.that引导的宾语从句,如果从句中还有其他事伤通进总望斤状语从句,引导宾语从句的t测院甚你hat不能省略.

Tellhimthatifheisathome,I'llcalltoseehim.

二等罗史待足烟落有且,that引导定语从句要注意以下几点:

1.定语从句中缺主院参官植型语,修饰人时用who/that,修饰物时用固答队已振识府形强调which/that引导.如:

Isthisthefac老月torywhich/thatmakesTVsets

Themanwho/thatvisitedourschoolisfromAustralia.

2.从句中缺宾语,修饰人时用who/whom/that或省略引导词;修饰物时用which/that或省略引导词.如:

Gonearethedayswhich/thatwespenttogetherinthevillage.

Heisthemanwho/whom/thatIthinktobeworthyofourpraise.

3.用that不用which的七种情况:

①先行词前有形容词最高级或序数词修饰时,用that不用which引导.如:

ThisisthebestplacethatIhaveevervisited.

②先行词为little,much,all,none,few,(the)one,something,everything,nothing,anything等不定代词时,用that引导.如:

④先行词前有any,all,no,few,every,some,little,much,(the)very,(the)only,(the)last等词修饰时,用that引导.如:

⑤先行词为which时,为了避免重复,用that引导.如:

Whichisthebookthatyouboughtyesterday

⑥先行词在从句中作表语时,常用that引导.如:

Shanghaiisnolongerthecitythatitusedtobeinthe1930's.

⑦当主句是Therebe...句型时,用that引导.
