同學們，上次發了八下unit5的詞彙講解，你們掌握了嗎？今天我們繼續掌握中考必考語法點感嘆句，你們是不是每次糾結到底用what or how,糾結了半天是不是還是選錯，今天我們好好來學習吧以及過去進行時的用法。
一. 感嘆句.
英語感嘆句的開頭要怎麼區分使用 what 和 how？
1. what 引導的感嘆句
What 引導的感嘆句，有四種句子結構：
① What +a/an+adj+可數名詞單數+主語+謂語
如： What an intelliegnt boy he is!
What a beautiful girl (she is ) ! 多麼美的姑娘呀 !
What a clever boy ( he is ) ! 多麼聰明的男孩呀 !
② What+adj+可數名詞複數+主+謂
如： What good children they are!
What interesting pictures ( they are ) ! 多麼美的圖片呀 !
What tall buildings ( they are ) ! 多麼高的樓呀 !
③ What +adj+不可數名詞+主+謂
如：What fine weather it is today!
What delicious food ( it is ) ! 多麼可口的食物呀 !
What bad weather ( it is ) ! 多麼壞的天氣呀 !
④ What+n+主+謂
如：What noise they are making!
規律: what + ( a\ an ) + 形容詞+ 名詞 ( + 主語 + 謂語) + !
名詞為不可數名詞或複數名詞時, 形容詞前面不能有a\ an .
2. how 引導的感嘆句
How 引導的感嘆句，有三種句子結構：
① How+adj/adv+主+謂
如: How heavy the box is ! 多麼重的箱子呀!
How fast he runs ! 他跑得多快呀!
How fast he runs!
② How +adj+a/an +可數名詞單數+主+謂
如：How careful a girl is ! 多麼細心的姑娘呀!
③ How +主+謂
如：How time flies!
如果說明的是人或物, 兩種感嘆句可替換.
二、過去進行時:
1. 概念和用法：過去進行時
表示在過去某一時刻或某一段時間內進行或發生的動作。
其形式為was /were + V-ing。
常與表示過去的時間狀語連用，如：last night,last Saturday等；或者與when,while,as引導的過去時間狀語連用。
例如：We were watching TV from seven to nine last night.
昨天晚上七點到九點的時候我們在看電視。
2.過去進行時的用法：
（1）過去某一時刻正在進行的動作。
When I called him , he was havingdinner .
(2) 過去某段時間正在進行的動作。
I was reading the whole morning yesterday .
(3) when \ while 引導的時間狀語從句中，過去進行時的使用：
----- when \ while 當……的時候
While引導的從句中, 動詞用過去進行時或表示狀態的延續性動詞
when引導的從句中, 動詞用過去式
Mary was having dinner when I sawher .
The weather was fine while we were in Beijing.
While were talking, the teacher came into the classroom .
--------while 然而, 可是
Tom is very confident while Mary is shy and quiet .
Tom很自信可是Mary既靦腆又文靜.
3．過去進行時的構成：
構成過去進行時常由「助動詞be的過去時was/were+現在分詞」構成。was not常簡寫為wasn't, were not簡略為weren't。
（1）肯定句：主語 + was \ were +動詞ing形式 + 時間狀語。
Iwasworking in the office .
（2）否定句：主語 + was \ were + not + 動詞ing形式 + 時間狀語。
（3）疑問句：was \ were + 主語 + 動詞ing形式 + 時間狀語 ？
肯定回答：Yes , 主語 + was \ were .
否定回答：No, 主語 + was \ were + not .
Wereyou working in the office last night ?
Yes, Iwas . No , Iwasn’t .
（4）特殊疑問句：特殊疑問詞+was \ were + 主語 + 動詞ing形式 + 時間狀語 ？
What were youdoing last night ?
4.一般過去時與過去進行時用法比較
一般過去時表示在過去某個時間發生的動作或存在的狀態（強調一次性動作）；
而過去進行時則表示在過去某一時刻或某段時間正在進行的動作（強調反覆的動作）。
Mary wrote a letter to her friend last night.瑪麗昨晚給她的朋友寫了封信。（寫完了）
Mary was writing a letter to her friend last night.瑪麗昨晚一直在給她的朋友寫信。（不一定寫完）
We built a bridge last winter.去年冬天我們修了一座橋。（建成了）
We were building a bridge last winter.去年冬於我們在修一座橋。（一直在修，不涉及結果）
四、 通常不能用於過去進行時的動詞主要有：agree,is,am,are,believe,belong,care,forget,hate,have（擁有），hear,know,like,love,mean,mind,notice,own,remember,seem,
suppose,understand,want,wish等。
例如：
誤：I wasn『t understanding him.
正：I didn『t understand him. 我不明白他的意思。
三、八下unit5【話題寫作】
Susanna所在的城市昨天晚上發生了一場地震。很幸運，地震並不強烈，他們全家安然無恙。假如你是Susanna請描述一下地震發生時家裡人的活動情景，80詞左右。

My name is Susanna. In our city, there was an earthquake at 8:32 yesterday evening.
At that time, I was takinga shower in the bathroom. My mother was cleaning up the kitchen and my father was watching TV in the livingroom. My elder sister Alice was working on her computer in her room. We were very scared.
Luckily, the earthquake was not heavy and it didn’t last long. And we were all safe.
