正如各位考生所了解的，非谓语动词仅有三类形式：to do，-ing和-ed三种形式，但是它们的用法却十分广泛，它向来都是各类英语考试的“宠儿”，无论是单项选择题，还是完型填空题、阅读理解题，甚至是在翻译题中也会有所涉及。为了更好地帮助各位参加教师招聘考试的考生更好地掌握非谓语动词的用法，笔者有意在接下来的内容中跟大家分享一下自己总结为出来的一些解题秘诀，并在秘诀后面附上相应的题目来解释这些秘诀的适用范围。根据这些秘诀，相信同学们应该能够更轻松地应对非谓语动词的出题套路!
秘诀七、be+-ed+介词结构常可把be去掉保留-ed+介词做状语。
例13.Michael’s new house is like a huge palace, ______with his old one.
A. comparing B. compares
C. to compare D. compared
【解析】“和……相比较”结构为be compared with，现在做句子的状语，所以只保留非谓语动词，把动词be去掉，答案为D。
例14._______with a difficult situation, Arnold decided to ask his boss for advice.
A. To face B. Having faced
C. Faced D. Facing
【解析】“面对”结构为be faced with, 现在做句子的状语，所以只保留非谓语动词，把动词be去掉，答案为C。
秘诀八、非谓语动词作状语，其逻辑主语必须和句子主语保持一致，和句子主语构成主谓关系时用-ing形式，构成动宾关系是用-ed形式。其逻辑主语和句子主语不一致时，要在非谓语动词前加逻辑主语，构成独立主格结构。
例15.____twice, the postman refused to deliver our letters unless we changed our dog.
A. Being bitten B. Bitten
C. Having bitten D. To be bitten
【解析】本题考查非谓语动词作状语，其逻辑主语应和句子主语the postman一致，the postman应该是被咬，所以答案为B。
例16._______ in the fields on a March afternoon, he could feel the warmth of spring.
A. To walk B. Walking
C. Walked D. Having walked
【解析】本题考查非谓语动词作状语，其逻辑主语应和句子主语he一致, he 和walk应该是主动关系，所以答案为B。
例17.While watching television, __________.
A. the doorbell rang B. the doorbell rings
C. we heard the doorbell ring D. we heard the doorbell rings
【解析】根据“非谓语动词作状语，其逻辑主语必须和句子主语保持一致”的原则，watching的逻辑主语应和后面句子主语一致，所以句子主语应为“we”，答案为C。
例18.The children went home from the grammar school, their lessons ____ for the day.
A. finishing B. finished
C. had finished D. were finished
【解析】本题没有连词，所以后面应用非谓语动词，the lessons是非谓语动词的逻辑主语，和非谓语动词构成独立主格结构。根据句意应是“被完成”，所以答案为B。
