总述: 谓语动词的变化形式取决于时态和语态: 英语的时态有十六种, 中学英语中有十二种常见的时态; 语态有两种, 即主动语态和被动语态
1.在主动语态中, 各种时态的谓语动词的一般形式如下:
一般 进行 完成 完成进行
现在 do / does am / is / are doing have / has done have / has been doing
过去 did was / were doing had done had been doing
将来 shall / will do shall / will be doing shall / will have done X
如果谓语是be动词, 则可用be动词的适当形式( be / am / is / are / was / were / been)代替以上表格中的黑体字部分. 此外, 过去将来时的形式是: should / would do或should / would be
2.在被动语态中, 各种时态的谓语动词的一般形式如下:
一般 进行 完成 完成进行
现在 am / is / are done am / is / are being done have / has been done X
过去 was / were done was / were being done had been done X
将来 shall / will be done X shall / will have been done X
另外, 过去将来时的被动语态形式是should / would be done
主动语态

d. By the middle of last month I had lived in Beijing for five years.

被动语态

带有情态动词的被动语态的构成: 情态动词 + be +过去分词

三.主动句变被动句:

→I was given ten minutes to decide whether I should accept the offer.
2.带有宾语从句的主动句变被动句时, 宾语从句变成主语从句, 通常不位于句首, 句首用形式主语it

a. My brother gave me a birthday present.
→I was given a birthday present. / A birthday present was given to me.
4.带有复合宾语 (即宾语+宾补) 的主动句变被动句时, 宾补的形式一般不变, 只是名称变成了主补, 但当宾补是不带to的不定式时, 要变成带to的不定式
a. I saw him play near the river. He was seen to play near the river.
5.含有短语动词的主动句变成被动句时, 不要遗漏短语动词中的介词或副词
a. The children must be taken good care of. / Good care must be taken of the children.
四.应注意的问题:
1.“be+过去分词”不一定是被动语态, 也可能是系表结构
a. The children were excited at the news.
b. We are interested in the English novel.
c. The mother was worried about her son’s absence.
2.有些动词形式上用主动语态时含有被动意思

c. This pen writes quite smoothly.这支笔很好使
d. This dish tastes good.这道菜味道不错
e. This kind of cloth feels smooth and soft.这料子摸起光滑柔软
3.不是所有的及物动词都有被动语态, 某些表示状态或关系的动词或短语动词只有主动语态, 而无相对应的被动语态. 常见的这类动词有: cost花费, fit适合, have有, hold容纳, lack缺乏, own拥有, suit适合, fail失败, belong to属于, agree with同意
