20. 被动语态 1) 被动语态构成：助动词be + 及物动词的过去分词。

助动词be 必须与主语的人称和数量保持一致，并有时态的变化。

The man was fooled by the two boys. 2) 时态 ①一般现在时 助动词 be + 动词的过去分词 Spanish is spoken as the official language there. ②一般过去时 助动词 was/were + 动词的过去分词 The man was fooled by the two boys. ③一般将来时 will/ be going to do + be + 动词的过去分词 The 2008 Olympic Games will be held in Beijing. ④现在完成时 have /has + been + 动词的过去分词 The book has been translated into several languages. ⑤带有情态动词的被动语态 情态动词 + be + 动词的过去分词 More trees must be planted 21. 现在进行时表将来 用现在进行时的结构表示将来的意思(主要表计划安排好而不容改变的打算)。

作表语：The problem is what to do next. 问题是接下来该干什么。

作宾语：I don’t know how to get to the park. 我不知道怎样到达公园。

2) wh- +to do这一结构在实际运用中作宾语更常见，尤其是宾语复合句变为简单句。

She doesn’t know how she can finish the work. = She doesn’t know how to finish the work. Tom asked me where to go. = Tom asked me where I would go. 注意：由于“wh- +to do”这一结构中不定式的动作是个尚未发生，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。

I don’t know what to do next. 我不知道下一步该做什么。

= I don’t know what I should do next. I don’t know how to remember new words 我不知道怎么样记新单词。

= I don’t know how I can remember new words. I don’t know where to find a pen pal. 我不知道在哪里能找到一个笔友。

宾语补足语的结构形式：及物动词 + 宾语 + 宾语补足语（名词、形容词、不定式、分词或介词短语） We all make him a monitor in our class. (名词作宾补) Computers have made the work place safer and better. (形容词作宾补) I agreed her to send her to school. (不定式作宾补) They keep their hearts beating well. (现在分词作宾补) I found every student in good health. (介词短语作宾补) 2) 注意以下特殊结构： ①find it +形容词+to do sth. 此处it作形式宾语，真正的宾语是后面的不定式，形容词作宾补。

Some students found it easy to study English well. ②keep sb. /sth. + 形容词 We should keep our classroom clean. ③make sb. /sth. + 宾补（形容词、名词、省略to的不定式） We had better make our city move and more beautiful. She made him a superstar. 她让他成了巨星。
