Fill in the blanks accrding t grammar fcus.
在英语中，动词有两种语态，即主动语态和被动语态。被动语态的基本结构是“助动词 be + 及物动词的过去分词”，其中助动词be有人称、数和时态的变化,其变化规则与be作为连系动 完全一样。
1.主动语态变为被动语态的方法
第一步:将主动语态的宾语改为被动语态的主语；第二步:将主动语态的谓语改为“be+及物动词的过去 分词”结构；第三步:将主动语态的主语改为介词by的宾语，放在谓语之后(有时可省略)。如图示：
They (主语）grw (谓语）tea (宾语）in the suth-east f China.
Tea (主语）is grwn (谓语）by them in the suth-east f China.
2. 被动语态谓语动词的构成
主语+be+ dne(过去分词)+其他成分
其中be动词有人称、时态和数的变化
1)一般现在时被动语态谓语动词：
主语+am\is\are+ dne(过去分词)+其他
The classrm is cleaned every day.
Ftball is played by them n Sunday.
2) 一般过去式被动语态谓语动词：
Our classrm was cleaned just nw.
3.一般现在时被动语态的各种句式结构
4.一般过去时被动语态的各种句式结构
（1） 不知道谁是动作的执行者或没有必要知道谁是动作的执行者时。These bks are written fr children. I haven’t been tld abut it.（2） 需要强调动作的承受着即宾语时。Calculatr can't be used in the math exam. 计算器不能用于数学考试。The cup was brken by David.The bk is written by M Yan.（3）作客观说明时，常采用一种被动语态结构。It is\was said\believed\reprted +that … …
It is said that tea was invented by accident.
What did yu find ut?
探究一：含有情态动词的被动语态
结构为：情态动词(can, may, must, shuld\… +____+及物动词的_________。
be 过去分词
Many trees shuld be planted in the muntains. 应该在山上种许多树。
含有情态动词的被动语态谓语动词句型结构
肯定：情态动词+ be +动词的过去分词否定：情态动词+nt+ be +动词的过去分词一般疑问句：情态动词+主语+be+动词的过去分词？特殊疑问句：疑问词+情态动词+主语+be+动词的过去分词？
Teenagers shuld be allwed t g shpping.

(改为被动语态)Smart phnes t take pictures instead f cameras.
The wrk must be dne
shuldn’t be allwed

探究二：含有宾语从句的主从复合句中的否定转移的用法。
当动词think, believe, suppse, imagine, expect, feel的主语是第一人称、谓语动词为没有任何副词修饰的一般现在时，它们的否定式实际上是对宾语从句的否定。表示说话者提出一种委婉的看法或主张。
I think that he will help us. —I dn't think that he will help us. 我认为它不会帮助我们。I believe that he is right. —I dn't believe that he is right. 我认为他不对。I suppse that he likes it. —I dn't suppse that he likes it. 我想他不喜欢它。
I dn’t think sixteen-year-lds shuld be allwed t drive.
动词前有其他副词修饰时，否定不转移。如：I really dn't think it's necessary fr us t g there nw. 我的确不认为我们有必要去那儿。I feel strngly that he shuldn't d such a thing. 我强烈地认为他不应该做那样的事。
应该翻译为：我认为十六岁的孩子们不应该被允许开车。
