求主语从句的解析和答案4,
9.It worried her a bit ______________ her hair was turning gray.
A.whether B.that
C.what D.when
10.What I say and think ___ none of your business.
A.is B.are C.has D have
答
9.这是主语从句,it是形式主语,而后面的从句her hair was turning gray
是真正的主语,而这个从句是完整的,所以只需要连接词that即可.
10.What I say and think 是主语从句,主语是一句话的话,系动词用单数,none of your business意思是和你无关,整句话的意思：我所说的和想得都和你无关.
