一、被动语态的构成形式
被动语态由“be＋过去分词”构成，be动词有人称、数和时态的变化。被动语态的构成形式还有：get/become＋过去分词。各种时态的被动语态形式如下(以动词give为例)：

三、主动形式表示被动意义
1．“系动词feel，sound，taste，look，smell，appear，seem，turn，stay，become，get，grow，keep等＋形容词/名词”构成系表结构，常常以主动形式表示被动意义。
This kind of wool shirt feels soft and sells well.
这种羊毛衫摸起来很软，卖得很好。
2．当sell，read，cut，wash，write，open，wear，run，burn等不及物动词后带状语(well/easily等)修饰，用来表示主语内在的品质或性能时用主动形式表示被动含义。

3．在need，want，require，deserve，bear等动词、worth等形容词的后面，动名词主动形式表示被动意义，其含义相当于动词不定式的被动形式。

考点六 虚拟语气(高考不作要求，只作了解)
单句语法填空
1．(2019·浙江台州模拟考试)It's a pity that you were late, otherwise you ________(see) the star Rain from Korea.
would have seen [句意：很遗憾你迟到了，要不然你就会见到从韩国来的明星Rain了。主句中用的是过去时，otherwise表示句中的“你”并没有见到那位明星是客观事实，故此处是与过去事实相反的虚拟语气，故用would have done结构。]
2．I should not have laughed if I ________(think) you were serious.
had thought [句意：如果我(当时)认为你是认真的，我就不会笑了。主句中谓语动词使用should not have laughed，表明与过去的事实相反，从句谓语动词应该使用had done形式。]
3．(2019·西安九校联考)Don't handle the vase as if it ________(be) made of steel.
were [句意：不要把那个花瓶当作是钢做的那样搬运。as if引导的是与现在事实相反的虚拟语气，谓语动词应用一般过去时，be动词用were。]
4．(2019·湖北武昌区高三调考)If we ________(make) adequate preparations，the conference wouldn't have been so successful.
hadn't made [句意：如果我们没有做好充分准备的话，会议就不会如此成功。分析句子结构可知本句是一个虚拟语气句式，根据主句中的wouldn't have been可知是对过去事情的虚拟，因此if条件从句要用had done形式来表示对过去发生事情的虚拟。]
一、if条件句中的虚拟语气
虚拟条件句 虚拟情况 | 主句 | 从句 |
与现在事 实相反 | 主语＋should/would/ could/might＋do | if＋主语＋过去 式(be用were) |
与过去事 实相反 | 主语＋should/ would/could/might ＋have done | if＋主语＋had ＋过去分词 |
与将来事实 可能相反 | 主语＋should/would/ could/might＋do | if＋主语＋过去 式/were to do/ should＋do |

Grace doesn't want to move to New York because she thinks if she were to live there，she wouldn't be able to see her parents very often.
格蕾丝不想搬到纽约，因为她认为如果住在那里，她就不能经常看到她的父母了。
[易错提醒] 1如果在表示虚拟语气的if从句中含有were，had或should，可将if省略，然后将were，had或should移至主语之前。 2如果主句和从句是对不同时间的事实的虚拟，则被称为错综虚拟语气。此时主句常有明显的时间状语。 |
二、含蓄条件句的虚拟语气
有时假设的条件不通过条件状语从句表达出来，而是隐含在某些词或短语中，或隐含在上下文中，这叫含蓄虚拟语气。常用的这类词或短语有：without(要是)没有；but for要不是；otherwise/or否则等。
—Do you have Betty's phone number?
——你有贝蒂的电话号码吗？
—Yes.Otherwise，I wouldn't have been able to reach her yesterday.
——有，不然我昨天就联系不上她了。
Many of the things we now benefit from would not be around but for Thomas Edison.要不是托马斯·爱迪生，我们现在从中受益的很多东西就不会存在。

1．在名词性从句中的运用
(1)在表示要求、命令、建议、请求等动词后的宾语从句中，以及这些动词的名词形式后面的同位语或表语从句中的谓语动词用“(should＋)动词原形”。常见的此类动词：一坚持(insist)、二命令(order，command)、三要求(require，demand，request)、四建议(suggest，advise，propose，recommend)。
She suggested that Dale join the debating team，believing that practice in speaking could give him the confidence and recognition that he needed.

He insisted that the problem (should) be discussed at the meeting.他执意要求在会上讨论这个问题。
My desire is that we (should) not quarrel over such things again.
我的希望是我们不再为这样的事情争吵了。
[易错提醒] 当suggest作“暗示，表明”，insist作“坚持认为”讲时，从句要用陈述语气。 |
(2)在“It is/was＋adj./done＋that...”句型中，从句中的谓语动词用(should)＋动词原形。常见的形容词或过去分词有：important，necessary，strange，suggested，ordered，advised，requested，demanded 等。
It is necessary that we (should) clean the room every day.

我们宁愿女儿待在家，陪在我们身边，但是选择权在她手上，毕竟她不再是个孩子了。
2．三个固定句式中的虚拟语气
虚拟情况 句式 | 虚拟 现在 | 虚拟过去 | 虚拟将来 |
if only引导的条 件句及感叹句 | 过去式 | had＋ 过去分词 | would/could/might ＋动词原形 |
as if/though引 导的表语从句 及方式状语从句 | 过去式 | had＋ 过去分词 | would/could/might ＋动词原形 |
It is (high) time that... | 过去式或should＋动词原形 | ||

确实到了我们采取措施解决问题的时候了。
Look at the trouble we are in. If only we had taken our teacher's advice！看看我们所处的困境，要是我们当初听从老师的建议该多好！
[易错提醒] 当as if/though引导的句子所叙述的是真实的或极有可能发生或存在的事实时，从句要用陈述语气。 |
【技法点拨】
语法填空的一个完整句子中若没有别的谓语动词，或者虽然已有谓语动词，但需填的动词与之是并列关系时，所给动词就是谓语动词，就要考虑动词的时态和语态，还要注意主谓一致和虚拟语气。
