托福语法常见谓语动词的注意事项
一、短语动词中的被动语态
有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。
【例如】The meeting is to be put off till Friday. Women were looked down upon in the past in China. The out of date teaching method must be done away with. Don’t worry, everything will be attended to in good time. The poor child was laughed at by his classmates because he failed his exams. The children are taken good care of by the teacher.
这类可用被动语态的“动词＋介词/副词”词组还有：depend on, make use of, bring about, put forward, send for, talk about, bring up, put on, think over, call off等。
二、非谓语动词的被动语态
非谓语动词的各种形式也有被动语态，一般常用的是一般体和完成体的被动语态，例如: It is a great honor for him to have been elected a model worker. (不定式完成体的被动语态)This new teaching method has the advantage ofshavingsbeen tried a number of times by experienced teachers. (动名词完成体的被动语态）
三、不使用进行时态的动词
凡动词表示人的思想、感情、态度和愿望等时一般不能用进行时，除非强调短暂性或含义发生变化。如感觉动词：appear, feel, hear, perceive, see, seem, smell, taste等；如表示心理和感情的动词：choose, desire, doubt, hate, love, hope, intent, like, prefer, want, believe, mean, mind, think, remember等；如表示存在和所属关系的动词belong, comprise, contain, equal, have, cost, hold等。
【例如】I believed what he was saying.They love each other.The food tastes delicious.The soup contains too much salt.As we walked，she felt a joy she could not restrain.
