高一英语题目啦

(That )he will go to teach in a faraway village surprised us now.为什么用that，that用在这里是什么意思呢
After (what )seemed like several hours,he came out of the room without saying a word.为什么用what?

Answer 1

你可以看一下，一个句子的基本结构不外乎主谓宾，主系表，第一个句子可以分成两部分看
1.he will go to teach in a faraway village
主语 谓语 （宾语 省略）
2.。。。。 surprised us now
从1.看是一个完整的句子，什么成分都不缺，但是 1.又可以作为2.的主语 ，所以用that，引出一个从句，并无实际意义
第二个句子，
After (what )seemed like several hours,he came out of the room without saying a word.
主语 系 表
在填空处缺少一个主语，所以用what，翻译为在似乎看起来几个小时之后，他一句话没说走出了房间

Answer 2

that用来引导从句，‘he will go to teach in a faraway village ’在此用作主语，所以要加that。

’seemed like several hours‘ 是定语 ，所以前面加一个what代替主语。
