重点语法
一般现在时的被动语态英语语态有主动语态和被动语态两种。
主语是动作的执行者，叫主动语态。如：We clean the classroom. 我们打扫教室。
主语是动作的承受者，叫被动语态。如：The classroom is cleaned (by us).教室被（我们）打扫。
1.被动语态的构成：助动词be+及物动词的过去分词+（by+宾语）其中by意为“被……；由……”，表动作的执行者。如：The glass is broken by that boy.玻璃杯是那个男孩打破的。
be有人称、数和时态的变化，其肯定式、否定式、疑问式的变化规则与be作为连系动词时完全一样。如：English 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 isn’t.
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 stolen.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.  Rice is grown (by people) in the south.(2)  She takes care of the baby.  The baby is taken care of (by her).

重点语法
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 don’t know what to do.=I don’t know what I should do.She can’t decide which to buy.=she can’t decide which she will 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 don’t know what I should do.=I don’t 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.)
