托福阅读干货主语从句

Hello大家好,今天我们来讲解一下在托福阅读中的主语从句吧!同学们对主语从句的了解有多少呢?让我们先来看一下主语从句的定义

主语从句即句子充当主语,或者it做形式主语:it+谓语+主语从句.

那我们如何识别主语从句呢?

当句子在充当主语的时候,常见从句关系词来开头,例如:where, when, why, where, whether, who, that...,一起来看一些例句:

一、that引导的主语从句

同学们来辨别一下下面两个句子的主语从句在哪里:

-- 首先先识别句子的that关系词,然后再来确认相对应的主语从句

👉1) That he is still alive is a wonder.

[主语从句]:that he is still alive -- 在句子中充当主语的成分

[整句翻译]:他仍然活着是一个奇迹

👉2)That he should have ignored the working class was natural.

[主语从句]:that he should have ignored the working class -- 在句子中充当主语的成分

[整句翻译]:他忽略工人阶级是很自然的

二、 whether引导的主语从句

同学们来辨别一下下面两个句子的主语从句在哪里:

-- 首先先识别句子的whether关系词,然后再来确认相对应的主语从句

👉1)Whether it will do us harm remains to be seen.

[主语从句]:whether it will do us harm

[整句翻译]:它是否对我们有害还有待观察

👉2)Whether they would support us was a problem.

[主语从句]:whether they would support us

[整句翻译]:他们是否会支持我们还是个问题

三、形式主语

形式主语出现时,句子会呈现it+谓语+主语从句的形式,而句子真正的主语会被移到句末

同学们来分析一下下面句子中的形式主语以及主语从句在哪里:

-- 首先先识别it引导的形式主语,然后再识别关系词引导的真正的主语从

👉1)It is appropriate that this tax be abolished.

[形式主语]:it is appropriate

[主语从句]:  that this tax be abolished

[整体翻译]:废除这个税是恰当的

👉2) It is a problem whether they would support us.

[形式主语]:it is a problem

[主语从句]:whether they would support us.

[整体翻译]:他们是否会支持我们还是个问题

了解清楚了之后我们来看几个长一些的句子练习一下吧:

👉1)It is unlikely that tuna can remain profitable while supplying so much expensive food for the tuna.

思考:这个句子中的主语从句在哪里呢?是否出现形式主语

[形式主语]:it is unlikely

[主语从句]:that tuna can remain profitable while supplying so much expensive food for the tuna.

[整体翻译]:给吞拿鱼昂贵食物的同时还保持高利润是不太可能的

👉2)It became clear that the sequences of rocks sometimes differed from region and that no rock type was going to become a reliable time marker throughout the world.

思考:这个句子中的主语从句在哪里呢?是否有出现形式主语

[形式主语]:it became clear

[主语从句]:that the sequences of rocks sometimes differed from region and that no rock type was going to become a reliable time marker throughout the world.

👉3)That you are coming to London is the best news I have heard this long time.

思考:这个句子的主语从句在哪里呢?是否有出现从句引导词来辅助判断?

[主语从句]:that you are coming to London -- 在句子中充当主语成分

[整体翻译]:你要来伦敦是我这么久以来听到的最好的消息
