20、nglish is widely spoken around the world. （肯定式）English is not widely spoken around the world. （否定式）Is English widely spoken around the world? （疑问式）Yes, it is./No, it isnt.2 被动语态的用法：（1）在没有指明动作的执行者或者不知道动作执行者的情况下可用被动语态。如：This coat is made of cotton.这件大衣是棉制的。（2）要强调动作的承受者而不是执行者时，用被动语态。如：Her bike is stole

21、n.她的自行车被偷了。 3 主、被动语态的转换：主动语态：主语+及物动词谓语动词+宾语（+其它） 被动语态：主语+be+及物动词的过去分词+by+宾语（+其它）注意：（1）主动、被动互转时，时态不变。（2）主动句的主语是代词的主格形式，变成被动态by的宾语时，要用宾格形式。如：(1) People grow rice in the south.

27、 语法学习wh- +to do wh-是指when, where, which, who(m)及how等连接词，它们和动词不定式连用，即为wh- +to do结构。这种结构在句中常作主语、表语和宾语，作宾语时可以转换为宾语从句。(对于谓语动词来说，wh- +to do这个不定式动词的动作是个尚未发生的动作，所以在转换成宾语从句时，通常须加情态动词或用将来时表示未来。)如：I dont know what to do.=I dont know what I should do.She cant decide which to buy.=she cant decide which she will

28、 buy.反之，如果主句中的主语与宾语从句中的主语一致时，宾语从句（由疑问词引导）通常可以与“疑问词+不定式”互相转换。如：I dont know what I should do.=I dont know what to do.如果不一致就不能转换。I want to know what Mary will do.(不能说:I want to know what to do.)
