So difficult did I find ___ to work out the problem that I decided to ask my partner for help.
A. myself
B. us
C. it
D. that

Answer 1

答案C
考察代词用法,myself我自己,us我们的宾格形式,这两个代词都是指人. It时它的意思,一般只代某一事物（即句子中的宾语）或作形式主语或宾语，that时那个的意思,可指代一整句话。根据题意find的实际宾语是work out the problem，故用it做形式宾语，选C。我发现解决这个问题太难了，因此我决定向我的伙伴请求帮助。"
