what was it ( )made them so busy ( ) they had zero time for outdoor sports a
A.which,that B.that ,that C.that,which D.which,which
我主要是不懂第一个空为什么要用that,怎么不能使用which,也就是说我的疑问是为什么它一定是个强调句,而不是定语从句

相信你已经知道强调句的用法了吧,我就不多说了.而从内容上说which引导的非限制性定语从句,which在句中会充当一定的成分,what was it本身就不是一个确定的事物,用which指代同样的不能使句意明确.而且语法上which指代句子时,which一般用“,”与前面的隔开.
再问：你这么说有一点问题，which不仅仅可以引导非限制性定语从句，它还可以引导限制性定语从句
再答：限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。在这里你如果理解为限制性定语从句，暂时去掉后，读一下，句意已经不明确了。所以不是限制性定语从句的相关内容。
