发布时间:2014-01-25 09:56:10  

【亲爱的同学:All things in their being are good for something. 天生我才必有用!】

What were you doing when the UFO arrived?

【基础知识】

一、过去进行时

1)用法:表示在过去某一时刻或某段时间内正在进行的动作。

2)构成:was / were + 现在分词(其中was是am、is的过去式,were是are的过去式)

3)时间状语:at that time/moment

at +点钟+ yesterday/last night

from +点钟 + to +点钟 + yesterday

二、过去分词的构成方法

现在分词变化规则:

1 .一般情况下直接加ing

think---thinking sleep---sleeping

2 .以不发音的字母e结尾的单词,去掉字母e,再加ing

wake---waking make---making

3.以重读闭音节结尾,呈现“辅,元,辅”结构的动词,先双写末尾的辅音字母,再加ing stop---stopping sit---sitting

4. 以ie结尾的动词,把ie改为y ,再加ing lie---lying

【即时训练】

1.When I came in, Alice _________(eat)hamburgs.

【重点、难点】

一、过去进行时与一般过去时的区别;

过去进行时:表示正在进行的动作。

e.g. was reading a novel last night.昨晚我在看小说。

一般过去时:表示一个完成的动作。

e.g.I read a novel last night .昨晚我看了一本小说。

二、1.while与when的用法。

- 1 -

when可指时间点,又可指时间段,从句中可用延续性动词,也可用非延续性动词。 while总是指一个时间段,从句中必须用延续性动词。

1)延续性动词指动作可以延续一段时间,而不是瞬间结束。如:work,study,drink,eat等。

2)非延续性动词指动作极为短暂,瞬间结束。如:Die,start,begin,finish,borrow,knock等。 如:Mary was having dinner when I saw her .(当我看到玛丽的时候,她正在吃饭.)

如:The weather was fine while we were in Beijing .(当我们在北京的时候天气很好.)

【即时练习】

用while或when 填空

1).What did you do ________ the UFO landed?

2).He called to see me _________I was looking for my bag.

三、.experience当经历讲,是可数的.当经验讲,是不可数的.

四、.around大约,环绕

例如:I get up at around 6 o'clock every day. 大约

五、.arrive ,reach, get to 三者都有“到达”之意.

1)arrive +at 或in

2)reach+地点

3)get to+地点

例如: They _______Beijing last night.(大地方用in)

They _______school gate at 3 o'clock yesterday afternoon.(小地点用at) They _______ Beijing.

They _______ Beijing.

六、.surprise使吃惊,动词

be surprised at(某人)很吃惊,形容词主要修饰人

surprising令人吃惊的,主要修饰物.

I am very surprised at the Yaan earthquake .

The Yaan earthquake is a surprising news.

七、. in the tree与 on the tree 的区别。

in the tree表示 : 在树上 。 on the tree表示: 长在树上 。

1)表示“某人发生某事”常用sth. happened to sb.如:What happened to you? 2)表示“某地/某时发生了什么事”常用“sth.+happened+地点/时间”。如:

3)表示“某人碰巧做某事”用 “sb.+happened+to do sth.”,如:

I happened to meet a friend of mine in the street yesterday.

11. look for 寻找(强调找的“过程”) find 找到(强调找的“结果”) eg. He looked for his lost key everywhere but couldn’t find it.
