① The house was very quiet, ____ as it was on the side of the
mountain.
A. isolated B. isolating C. being isolated D. having been isolated
② These surveys indicate that many crimes go _____ by the police,mainly because not all victims report them.
A. unrecorded B. to be unrecorded C. unrecording D. to have been unrecorded
分词做表语可以做系动词be的表语,也可以做其它系动词的表语,如go, feel,seem, look, remain等等。这些系动词后非谓语动词的饿用法规则是相同的。
7) to作为介词与作为不定式符号的选择
to可以是介词,也可以用来引导不定式,四级考试中对种类用法的考查也比较多。如:
① I have no objection _______ your story again.
A. to hear B. to hearing C. to having heard D. to have heard
② The traditional approach ____ with complex problems is to break down into smaller, more easily managed problems.
A. to dealing B. in dealing C. dealing D. to deal
③ The man in the corner confessed to _____ a lie to the manager
of the company.
A. have told B. be told C. being told D. having told
这类考题的考查方式有两种,一是四个选项中有两个相对的选项to do something 和 to doing something,这时考查的自然是to的性质;另一种是to在题干中,如③。
