八年级英语主语从句练习题40题1. ______ we need more practice is quite clear.A. WhatB. WhichC. ThatD. Whether答案：C。
解析：本题考查that引导的主语从句。
句子“we need more practice”是一个完整的句子，不缺成分，在句中作主语，表示“我们需要更多练习”这件事是很清楚的，这种情况下用that引导主语从句。
选项A“what”在主语从句中要充当主语、宾语等成分；选项B“which”表示“哪一个”，通常在从句中有选择意义；选项D“whether”表示“是否”，这里从句不表示疑问，所以这三个选项都不符合。

解析：“he will come to the party”是一个完整的陈述，在句中作主语，表示“他将来参加聚会”这件事让大家很兴奋，用that 引导。
选项B“what”在从句中要作成分；选项C“if”引导条件状语从句或宾语从句，不能引导这种主语从句；选项D“when”在从句中作时间状语，这里不需要，所以这三个选项错误。
3. ______ she likes reading books is known to us all.A. WhatB. ThatC. WhichD. Whether答案：B。
解析：“she likes reading books”句子完整，作主语表示“她喜欢读书”这件事是我们都知道的，用that引导。
选项A“what”在从句中需充当成分；选项C“which”有选择含义；选项D“whether”表示是否，这里不适用，所以这三个选项不正确。
