Question

英语语法问题求解。。。谢谢了？

Good speakers change the way they speak in different situations.
请问大家此句话里的 they speak in different situations是一个省略了that或in which的定语从句吗？那这里的that又在从句中作什么成分呢？是宾语吗？但是我怎么感觉把that放在宾语的位置后带进去那么别扭呢。 they speak (the way) in different situations ? 难道关系"代词"that在从句中充当的是“状语”吗？不是只有关系副词才能作状语吗.
请大家指点说明谢谢了。

我认为你的分析是正确的，其他问题回答如下：

1.because是从属连词，表示因果关系，可以引导原因状语从句，表语从句和主语从句。

2.it此处是普通代词，指代前文that。

it作为形式主语只是为满足语法上的需要，避免句子头重脚轻，它代替的是句子的逻辑主语，概括起来会有三种情况：不定式作主语、动名词作主语 和 名词从句作主语。

典型的句型如下：

从句作逻辑主语

It is so happened that the tickets were sold out.

It is extremely obvious that she has been lying about her identity.

It suddenly occurred to me that the message must have been hidden between the layers of the briefcase.

不定式作逻辑主语

It is very kind of you to give me a hand in time.

It is my pleasure to address the meeting.

It was pretty hard for him to bring up the child on his own.

动名词短语作逻辑主语

这类句子远不如前面两种出现率高，主要在（no good,waste,useless,no use,dangerous）等词语的后面用

It is no use reasoning with him.

It is no good reading in dim light.

也就是说，如果是在主从复合句中，it做形式主语一般出现在主句部分，后面带that或者of和for等介词。

此处并无此特征，判断为普通代词。

以上~~~

在英语定语从句中，若先行词是表时间的词语、表理由的reason和表方式的way时，同时定语从句里又缺状语，这是引导定语从句的关系词分别是：when/prep+which/(that); why/for which/ (that); in which/ (that), 这里面的that都是作状语，并且都可以省略。这种用法是语言在发展过程中演变而来的。甚至有时间名词引导时间状语从句的现象，其实就是省去了关系词that的定语从句。如：
Every time he comes to see me, he always gives me presents.
= Every time (that/when) he comes to see me, he always gives me presents.
By the time he was four, he had played the piano very well.
=By the time (that/ when) he was four, he had……
所以， 关系词that可以指人、指物、指时间、原因和方式；可以作主语、表语和状语； 作状语和作前面没有介词的宾语时都可以省略。
Good speakers change the way （that/in which）they speak in different situations.（that是作状语）
希望对你有帮助。

这是一个定语从句，当先行词way在从句中做状语时可以有三种情况，一个是用that引导，一个是用in which还可以省略引导词。这是一个特殊情况，that已经不同于关系代词了，不能把它和其他情况中的that同等看。

Answer 4

是定语从句，但不是省略了that，而是省略了by which或者with which，在句子里做方式状语。
意思是，优秀的演说家改变了在不同场合演讲的方式。
