简单句
Step 9 Language pints
Mr Jiang did nt knw what t d with the rbt.
江先生不知道怎样处理这个机器人。
(1) 此句包含“疑问词+动词不定式”。
此结构中的疑问词包括疑问代词wh、whm、what、which和whse以及疑问副词when、where和hw。此外,连接词whether也适用,但疑问副词why后不直接跟动词不定式。“疑问词+动词不定式”主要在句中作主语、宾语、表语、宾语补足语、同位语等。
When t hld the meeting has nt yet been decided.
何时开会还没有定下来。(作主语)
We must knw what t say at the meeting.
我们必须知道在会上说什么。(作宾语)
Tm had n idea which bk t read first.
汤姆不知道先读哪本书。(作同位语)
(2)“特殊疑问词+动词不定式”结构可以改写成相应的从句。
The dctr tld him when t take the medicine.
=The dctr tld him when he shuld take the medicine.
医生告诉他何时吃药。
—It’s imprtant fr us t knw ________ all the subjects.
—Yeah, grup wrk is my favrite.
A. hw t studyB. when t study
C. which t study D. what t study
解析:hw t study如何学习;when t study何时学习;which t study要学习哪一门;what t study学习什么。根据答语中的grup wrk可知小组合作是学习的方式,用hw。故选A。句意:“对我们来说知道怎样学习所有课程是重要的。”“是的,小组合作是我最喜欢的(学习方式)。”
