九年级英语主语从句练习题50题(带答案)

九年级英语主语从句练习题50题(带答案)1. ______ we need is more time.A. ThatB. WhatC. WhichD. It答案解析:B。
本题考查主语从句。
在这个句子中,“______ we need”是主语从句部分,在主语从句中缺少宾语,表示“我们所需要的(东西)”,what可以在主语从句中充当主语、宾语或表语等成分,所以这里用what。
that在主语从句中不充当成分,which表示“哪一个”,it不能引导主语从句,所以A、C、D都不正确。
2. ______ he will come to the party is not certain.A. WhetherB. IfC. ThatD. What答案解析:A。

“______ he will come to the party”是主语从句,表示“他是否会来参加聚会”,在主语从句中表示“是否”且引导主语从句只能用whether,if不能引导主语从句,that在句中无意义且不充当成分,what在句中要充当成分,所以B、C、D不符合要求。
3. ______ makes this shop different is that it offers more personalservices.A. WhatB. WhoC. WhateverD. Whoever答案解析:A。
此句中“______ makes this shop different”是主语从句,在这个主语从句中缺少主语,表示“使这个商店不同的((东西)”,what可以在主语从句中充当主语等成分,who表示“谁”,主要用于指人,whatever表示“无论什么”,有让步的含义,whoever表示“无论是谁”,也是指人,所以B、C、D都不合适。
