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作为连系动词完全一样。
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.
D yu remember hw we change active vice int passive vice?
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
Ftball is played by them n Sunday.
The trees are planted every year.
The hmewrk is dne every night.
English is spken every day.
D yu remember the passive vice predicative verbs谓语动词?
Lucy takes care f the cat .

He plays ftball n Sunday.
Ftball _______ (by him) n Sunday .
She waters flwers every day.
Flwers __________ (by her) every day .
are watered
He killed a hen yesterday.
A hen _________ (by him) yesterday .
Please change the active vice int the passive vice.
2)一般过去时被动语态谓语动词：
主语+was\were+ dne(及物动词的过去分词)+其他成分
Our classrm was cleaned just nw.
Tm made the new machine last week.
The new machine ______ ____ by Tm last week.
Thmas Edisn invented the electric bulb.
The electric bulb _____________ by Thmas Edisn.

The baby ate the biscuit.
The biscuit _________ the biscuit.
Smebdy stle my camera frm my htel.

7.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。
D yu understand the sentence?
I dn’t think sixteen-year-lds shuld be allwed t drive.
应该翻译为：我认为十六岁的孩子们不应该被允许开车。
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。
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。
