表示某种必然的趋势。
过去进行时的用法
2. 过去进行时常和always等表示频率的副词连用，表示过去频繁发生的习惯性动作，此时的过去进行时带有一定的感彩。

I wrote a letter last night.
我昨晚写了封信。
I was writing a letter last night.
我昨晚正在写一封信。
过去进行时的判断
1. 时间状语：

即当从句动作发生时，主句动作正在进行。此时从句常用非延续性动词，主句用延续性动词。
When the teacher came in, the students were talking. 老师进来的时候，学生正在交谈。
也可以表示为：
主句（一般过去时）+when/while从句（过去进行时）
The teacher came in, when/while the students were talking.
老师进来的时候，学生正在交谈。
过去进行时的句式
2. 过去进行时+when+一般过去时
即一个动作正在进行，这时发生了另外一个动作。此时when相当于at that moment,表示“就在那时”。
The students were talking when the teacher came in.
学生正在交谈，就在那时，老师进来了。
过去进行时的句式
3.主句（过去进行时）+while从句（过去进行时）
表示两个延续性动作在过去某一时刻同时进行, 不考虑动作的先后顺序, 主句和从句的谓语动词都用过去进行时, 连词常用while。例如:

一般现在时的被动语态
被动语态的构成
语态是动词的一种形式，表示主语和谓语的关系。当主语是动作的执行者时用主动语态（某人做某事）; 当主语是动作的承受者时，用被动语态（某事被人做）。
被动语态的结构为“助动词be+及物动词的过去分词(p. p. )”。被动语态的不同时态是通过be的时态变化来表示的, 其人称和数方面应与主语保持一致。
各种时态的被动语态
结构 例句
一般现在时：
主语+am/is/are+过去分词 The classroom is cleaned every day.
教室每天都被打扫。
一般过去时：
主语+was/were+过去分词 Our school was built in 1998.
我们的学校是在1998年建造的。
一般将来时：
主语+shall/will+过去分词 The sports meeting will be held tomorrow. 明天举行运动会。
现在进行时：
主语+am/is/are +being+过去分词 The car is being repaired.
车正在修理中。
各种时态的被动语态
过去进行时：
主语+was/were +being+过去分词 The machine was being painted then. 那时机器正在上油漆。
现在完成时：
主语+has/have +been+过去分词 The bank has been built.
银行已经建成了。
过去完成时：
主语+had +been+过去分词 I had been invited to visit Japan before I came here. 在来这儿之前我已经被邀请访问日本了。
过去将来时：
主语+should/would+过去分词 Ann told me she would be sent to America.安告诉我她将被派往美国。
含有情态动词的被动语态：
主语+情态动词+be+过去分词 The bike can’t be put here.
这辆自行车不能被放在这里。
含有情态动词的被动语态
含有情态动词的被动语态结构为：
主语+情态动词+be+过去分词
注意否定形式一般是在情态动词后加not,而不是在be动词后加not.
Anything here can't be touched.
这里的任何东西都不能碰。
被动语态的用法
1.不知道动作的执行者是谁。
This watch is made in China.
这块手表是中国制造的。
2. 没有必要指出动作的执行者是谁。
More trees must be planted every year.
每年都必须种更多的树。
被动语态的用法

世界上越来越多的人说汉语。
4. 句子的主语是物。

被动语态的特殊形式
1. 主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式作宾语补足语时, 变为被动语态时应加上不定式符号to。
We saw an alien get out of the UFO.
→An alien was seen to get out of the UFO.
2. 句中谓语是动词短语时, 变为被动语态时要注意其完整性。
Jack turned on the TV just now.
→The TV was turned on by Jack just now.
被动语态的特殊形式
3．主动表被动。
(1)feel, look, sound, smell, taste等系动词的主动语态表示被动含义。

(2)有些动词, 如sell, cut, drive, wash, clean, write, open, lock等, 作为不及物动词，与副词连用常用主动形式表示被动意义。This kind of cloth washes well．
这种布料很好洗。
被动语态的特殊形式
3．主动表被动。
(3)be worth doing的主动语态表示被动含义。
This book is worth reading. 这本书值得一读。
(4)want/ need+doing结构相当于“want/ need + to be done”,即不定式的被动结构。

我的自行车需要修理。
主动语态变为被动语态
1.在主动句变为被动句时，要注意主动句和被动句中时态应该一致，同时还应该注意被动句中主语的人称和数要与谓语动词保持一致。主动语态和被动语态的转换形式主要方法：
第一步：把主动语态中的宾语变为被动语态的主语，或宾格变成主格。
第二步：把主动语态的谓语变为be+过去分词。
第三步：把主动语态的主语放在介词by之后，或变宾格，用来说明动作的执行者，有时可以省略。
We asked him to sing a song.
He was asked to sing a song by us.
主动语态变为被动语态
2.双宾语及物动词变成被动语态时，将间接宾语变为主语。动词有：give，send， take， bring， teach， show， tell， make， buy， pass。
They gave the children many good books.
他们给了孩子们很多好书。
→The children were given many good books.
或将直接宾语变为主语，并在间接宾语前加介词to。
→Many good books were given to the children.
主动语态变为被动语态

当及物动词后找不到宾语时，往往是vt. sb. to do sth.结构，常用被动语态。

被动语态与系表结构
“be + p. p. ”表示动作时是被动语态; “be + p. p. ”表示主语所处的状态时是系表结构。
(1)含有“by +宾语”结构强调动作执行者, 此时为被动语态。
The window is broken.
窗户坏了。(系表结构)

我对这个消息真的感到很惊讶。
(5)系表结构通常只有一般现在时和一般过去时, 而被动语态可用于多种时态。
判断动作的执行者还是承受者
考查被动语态的题目，解题的关键是找出动作的执行者或承受者，这就要根据句子的意思进行判断，然后根据句子的时间，正确选择。

Computer in my life
The computer has become an important part of my life. Usually I use the computer to search for information and do some further reading. With the help of computer，I can get more knowledge easily in my free time. I not only communicate with my teachers and classmates by email，but also discuss questions with them online. What’s more，I can enjoy the music online and shopping on the Internet makes my life much easier. Sometimes CD-ROMs help me learn English and make me relaxed. Moreover，I can take part in some kinds of activities online.
In a word，the computer is really of great help to me. It brings me a more meaningful and colourful life.
