1、that是主語(yǔ)從句.
斷句如下：
The two men quarrelled bitterly
and (遞進(jìn)）
it was clear
that （that后面內(nèi)容代替it部分的內(nèi)容）
the argument could only be settled by a fight.
2、狀語(yǔ)從句.
It was not until his third match in 1790
that
he finally beat Humphries and became Champion of England.A match was held at Stilton, where both men fought for an hour.這里的where是狀從嗎第二個(gè)句子不是定從嗎？？Despite this, he was so extravagant that he was always in debt.這里的that呢1.是狀從。2.不是定從。是時(shí)間狀語(yǔ)從句的強(qiáng)調(diào)結(jié)構(gòu)。可轉(zhuǎn)換為he……，until……格式。3.be so……that，強(qiáng)調(diào)結(jié)構(gòu)，引導(dǎo)目的。也屬于狀語(yǔ)從句。順便說(shuō)一句，1、如果不是為了應(yīng)付考試，不要去研究這些。2、即便為了考試，也不要去深究。3、即便深究了，也不要太當(dāng)回事。過(guò)去就忘了吧，否則太難受……
