Question

--- What do you think of the young actress called Zhou Dongyu?
--- _______ lucky ______ her to play the lead role in the film called ‘ A Romance under the Hawthorn Tree’?(山楂树之恋)

A．It’s; of

B．That’s; of

C．It’s; or

D．That’s; for

Answer 1

A

试题分析：本句中it代替to play the lead role in the film做形式主语，that没有这个用法。It is+adj.+of sb.这里的形容词是用来描述主语的性格品质等特点；It is+adj.+for sb.是用来描述事物的，及能对主语造成何种影响。Or表示选择关系，前后结构要求一致。根据以上分析可知选A。她太幸运了……
点评：it可以替代句中的不定式或从句等, 充当形式主语或形式宾语，that则无此用法。另外形容词后表示主语的介词的选择也很重要，需多加联系。
