问题描述：
Can it have been on the sportsground ,()you lost your watch yesterday?
a;that b;which c;where d;in that
选a,我选了c,
这两个答案还是不够清楚啊……
这样一换倒是懂了……
答
就是选that，这里的that引导的是个同位语从句，that后面的句子代指的是前面的it.
回答完毕，不知道你满意不？
答
强调句,强调地点,把它弄成肯定句就容易看了.,
前边的句子不对-it can have been on
it can have been on the sportsground that you lost your watch yesterday.
