teaching aim: grasp the usages of the present perfect passive voice and use them freely
important and difficult points:
the usages of the present perfect passive voice
the present perfect passive voice
现在完成时被动语态由”has/have + been + 及物动词的过去分词”构成。使用现在完成时被动语态要注意以下几点:
1. 只带有一个宾语的动词变为被动语态时,将主动语态的宾语变为被动语态的主语。例如:
we have built many houses in the past ten years.
→many houses have been built in the past ten years.
2. 带有双宾语的动词,如give, send, bring, take, teach, show, tell, make, sing, write, read, sell, buy, tell, pay, lend, pass, promise等,变为被动语态时,可将其中一个宾语变为主语,另一个保留不动。例如:
we have given him the book.
→he has been given the book.
→the book has been given to him.
3. 带有复合宾语的动词变为被动语态时,只能将宾语变为主语,原来的宾补改为主语补足语。原来省略to的不定式作宾补的,被动语态中要用带to的不定式。例如:
i have told them to help you.→they have been told to help you.
i have made her work hard.→she has been made to work hard.
4. 短语动词变为被动语态时,要注意保持短语的完整性,动词后原有的介词或副词不可遗漏。例如:
they have referred to the books.→the books have been referred to (by them).
he has thought of a way of dong it.→a way of doing it has been thought of.
1.hundreds of jobs ________ if the factory closes.(XX全国春招)
a. lose b. will be lost c. are lost d. will lose
[解析]本句的意思是:如果工厂倒闭,那么将失去数百个工作岗位。lose a job意为”失业”。工作将被失去,要用将来时态的被动语态,因此排除答案a、c和d,答案选b。
2.the mayor of beijing says that all construction work for the beijing olympics ________ by XX. (XX北京)

1. in small groups, discuss what they have in common? 分小组,讨论它们的共同点。
[要点导航] in common 共有,公用(常与have,own等动词连用,在句中多作状语)。例如:
the two brothers own the company in common.
兄弟俩共有这家公司。
the two cultures ________________________.这两种文化具有许多相同之处。

(2)we just had nothing in common and i couldn't communicate with his dull business friends.
(3)i suddenly felt we had a lot in common.
tom and i have nothing in common.= i

common, ordinary和usual的区别:
common 指“共有的,公共的;共同的;常见的”。例如:
he is their common enemy.他是他们共同的敌人。
the problems are common to all societies.这些问题是所有社会的通病。
common作“普通的”讲可与ordinary换用。如“普通人”也可说成common people。
ordinary 意为“普通的,平淡无奇的”,指没有什么特别的地方。例如:
we are all ordinary people.我们都是普通人。
he is in ordinary clothes.他穿着平常的衣服。
usual 意思是“平常的,通常的,一向的”,含有遵循常规的、习惯性的、一贯如此的意思。例如:
tea is considered to be the usual drink of the british people.
茶被认为是英国人的日常饮料。
he made the usual mistakes that all beginners make.
他犯的就是那些初学这老犯的错误。
2. anyway, let’s go back to my history. 无论如何,让我们追溯一下我的历史。
anyway adv. 无论如何,反正(句子副词,等于anyhow。用于转换话题或回到原话题时)。例如:
a/an + adj. + 单数可数名词 + that-clause
such + adj.+ 复数名词 + that-clause
