随着报名AEAS考试的人数逐年增加，AEAS培训竞争也越来越激烈。AEAS模拟真题成了制胜的法宝。AEAS考试网为大家介绍的是to是介词还是不定式符号。

AEAS考试模拟真题：【题目】

We are looking forward to ________ from Mary.

A. hear

B. hearing

C. heard

D. have heard

【分析】

此题应选B。容易误选A，认为其前的to是不定式符号。

to有时是不定式符号，有时是介词。用作介词时，注意以下常见搭配：

look forward to 盼望

devote……to 致力于，献身于

pay attention to 注意 stick to 坚持

be used to 习惯于(但used to表示过去经常，to为不定式符号;be used to 表示“被用来……”时，to 也是不定式符号)

on the way to 即将成为 (但表示“在做某事的路上”时to是不定式符号)
