为什么选B

复合句You’d better begin the preparations now and the most important thing is to checYou’d better begin the preparations now and the most important thing is to check ______ the laboratory can be used for the tests.A.where B.when C.what D.that
意思决定的.
不是A,因为where意思不对,这里主语是实验室,所以不能用where了
不是C,因为what在从句是做主宾表的,而句子结构完整了,所以,不能用what
不是D,要去查一下,不是确定的,所以,不用that.
“去查一下什么时候实验室可以用来做试验”
也可以说whether
“去查一下实验室是否可以用来做试验”
意思也对的.
如果把check换成be sure
答案就选D
