一、现在完成时
语法探究
在上学期我们已经学习了有关现在完成时的相关知识,本单元在原来的基础上系统归纳,并学习have/has been to 和have/has gone to的区别。
1.用法
(1)现在完成时表示动作发生在________,对________造成了影响或产生了结果。不与表示过去的时间状语连用。例如:I've lived here for ten years. 我在这里住了10年了。(现在仍住在这里)
单元语法聚焦七
过去 现在
(2)现在完成时表示从过去开始一直________到现在的动作或保持的状态,强调的是________的情况,常与________和________引导的时间状语或so far, recently, in the past few years等时间状语连用。例如:
He has studied English for 5 years.
他学英语5年了。
2.have been, have gone 的用法
(1)“have been+________+地点名词”或“have been+地点副词”
单元语法聚焦七
延续
现在
for
since
in
的意思是“在某地待(多久)”,常与表示一段时间的状语连用。例如:
Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经三天了。
(2)“have been+________+地点名词”或“have been+地点副词”的意思是“曾经到过某地(多少次)”,表示现在已经不在那里了。可与just, ever, never等词连用。例如:
Miss Brown has just been to Japan twice.布朗小姐就去过日本两次。
(3)“have gone+________+地点名词”或“have gone+地点副词”
单元语法聚焦七
to
to
表示“到了某地或正在去某地的途中”。总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语。例如:
—Where is Tom? 汤姆在哪里?
—He has gone to the bookshop. 他去书店了。

二、被动语态
1.概述
语态是动词的一种形式,表示主语(动作的发出者或动作的承受者)和谓语之间的关系。语态分两种形式:________________和________________。主动语态表示主语是动作的执行者。被动语态表示主语是动作的________,即行为动作的对象。注意:不及物动词是没有被动语态的。
2.被动语态的构成和形式
单元语法聚焦七
主动语态
被动语态
语法探究
承受者
被动语态由“be动词+及物动词的过去分词”构成,be动词随着主语的人称、数、时态的变化而变化。各种时态的被动语态形式如下(以teach为例):
一般现在时: am/is/are+taught
一般过去时: was/were+taught
一般将来时: will/shall be+taught
过去将来时: would/should be+taught
现在进行时: am/is/are being+taught
单元语法聚焦七
过去进行时: was/were being+taught
现在完成时: have/has been+taught
过去完成时: had been+taught
含情态动词时: 情态动词+be+taught
3.被动语态的用法
(1)在没有必要指出动作的执行者时,“by+动作的执行者”可以省略。例如:I won't leave my office until my work is finished. 直到我的工作完成,我才会离开办公室。
单元语法聚焦七
(2)不知道动作的执行者是谁时,使用被动语态比较合适。例如:
Some new computers were stolen last night.
昨晚一些新电脑被偷了。(不知道电脑是谁偷的)
(3)短语动词是不可分割的整体,改为被动语态时要保持其完整性,介词或副词________(可以/不可以)遗漏。例如:
We must take good care of the young trees.
→ The young trees must be taken good care of.
(4)带双宾语的动词变为被动语态时,常有两种方法:把主动语态的
单元语法聚焦七
不可以
直接宾语变为被动语态的主语,间接宾语前通常加介词to或for; 或把主动语态的间接宾语变为被动语态的主语,直接宾语不变。例如:
My uncle sent me a Christmas present last year.
→ A Christmas present was sent to me by my uncle last year.
→ I was sent a Christmas present by my uncle last year.
(5)省略to的动词不定式在句中作宾语补足语时,若要改为被动语态,则要把省略的________还原。例如: They watched the children sing that morning. → The children were watched to sing that morning.
