Question

初三英语求解

Is this the factory __that___ you visited the other day?
Is this research center ___the one ___ foregin guest last week？

我觉得这两道题的结构差不多 但是为什么答案不一样？
这个答案可能不太对 求高手讲解 谢谢了

Answer 1

Is this research center ___the one ___ foregin guest visits last week？
这个句子变成陈述句就是，this research center is the one (that) foreign guest visits last week.
is后面缺少句子成分（表语），所以用 the one 作先行词；
the one (that) foreign guest visits last week.
这又是一个独立的宾语从句，that可以省略
Is this the factory __that___ you visited the other day?
陈述句形式是：this is the factory that you visited the other day.
this is the factory 成分完整，所以后面只是一个宾语从句

不知道这样你懂了没有

追问

Is this research center 变回陈述句是this research center is
Is this the factory 变回陈述句是this is the factory

请问这两个为什么不一样呢

追答

Is this research center 照你的想法是，你想变成 this is research center
但是你把research center作先行词，后面的部分the one (that) foreign guest visits last week.
是定语，也就是说research center是一个特指的地方，那就要用定冠词the了
Is this research center
Is this the factory
这两句的差别只在于这个the

Answer 2

第一个变成this is the factory that you visted the other day.
第二个变成this research center is the one foregin guest last week.
这下就很容易知道缺少的部分是什么了 第一个定语从句 第二个少先行词

追问

“第二个变成this research center is the one foregin guest last week.”

请问为什么是少先行词呢 先行词不是research center 吗

this is research center that foregin guest last week 不可以吗

追答

主语是this research center 第一句的主语是 the factory 主语不一样啊

追问

Is this “ the factory ”
Is this “research center ”
既然第一个主语是the factory ”
那么第二个不应该是“research center ”吗

Answer 3

第一句相信你明白，就不解释了。
第二句实际省略了the one(that). 这句先用了同位语the one, 来对the research center起强调作用，语气更强。后面的that可以省略，引导出定语从句。
