6、态中，主语是动作的执行者。如：The student wrote a song. 被动语态(Passive Voice): 在被动语态中，主语是动作的承受者。如：A song was written by the student. 主动语态变被动语态三步骤：1. 原来的主语变为宾语，其前加“by”；2. 原来的(直接)宾语提前作主语；3. 动词变为被动 be 过去分词(be要变化)如： Millions_of_people will watch the_final_match_on TV.

8、动表被动，如：look, sound, smell, taste, prove, feel。 This kind of cloth feels soft. My advice proved to be wrong. (2)当open, close, shut, lock, move等用作不及物动词且表示主语的某种属性时，通常用主动形式表示被动意义。他们通常与cant, wont等连用。 The door wont shut. (3)当read, write, wash, sell, clean, cook, burn, draw, cut, wear等词与well, easily, quick
9、ly 等副词连用时，常用主动表被动。 The cloth washes well. The poem reads smoothly. (4)某些表示开始和结束的动作(begin, start, finish, end, etc. )，当主语是物且不强调动作的执行者时，可用主动表被动。 The play ended at ten oclock. 4. 非谓语动词主动表被动的情况。 (1)不定式to blame, to let用作表语时，通常用主动表被动。 Who is to blame? 该怪谁呢？ The house is to let. 此屋出租。 (2)在“be 形容词to do”结构中的不定式通常用主动表被动。 The question is difficult to answer. (3)不定式用于某些动词的(have, have got, get, want, need)宾语后作定语时，当不定式逻辑主语和句子的主语一致时就用主动表被动，若不一致，则需用被动。 I have a letter to post. (自己寄) I have a letter to be posted. (请别人寄)
