there 還是 it　　

請(qǐng)看下面這道題：　　

_________ doesn’t seem to have been much difficulty in solving the problem.　　

A. It                        B. That                        C. There                        D. He　　

許多同學(xué)一看選項(xiàng)便想當(dāng)然地認(rèn)為，這是考查形式主語 it 的用法，所以便毫不猶豫地選了A。同學(xué)們仔細(xì)想想看，假若此題選形式主語 it，那么真正的主語在哪兒呢？沒有。其實(shí)，此題應(yīng)選C，屬 there be 句型一種比較復(fù)雜的表現(xiàn)形式，請(qǐng)看下面幾個(gè)句子，它們均屬there be 句型，但結(jié)構(gòu)一個(gè)比一個(gè)復(fù)雜：　　

There is much difficulty in solving the problem.　　

There seems to be much difficulty in solving the problem.　　

There seems to have been much difficulty in solving the problem.　　

There doesn’t seem to have been much difficulty in solving the problem.
