初學者學語法難度較大，但是可以另闢蹊徑，通過觀察來學習語法也不失為一個好辦法，只要前面學過了一般現在時，現在進行時等語法知識，這樣就可以循序漸進，就會為後面進一步學習其它語法知識打下了一定的基礎。
今天學習一般過去時，這一時態比較複雜，因為涉及到太多的動詞變形，有規則動詞和不規則動詞，需要大量的記憶。不過只要掌握了一般過去時的結構特點，再去記憶一些細節也就只是時間的問題了。
通過比較來學習一般過去時，兩者之間形成對比，特點各異，就可以很快掌握這一時態的結構和特點，前提是要認真觀察，一起來學習新的內容。
先讀一組一般現在時，複習和總結這一時態的特點
01一般現在時
Group1 一般現在時
1. I workin a bank.
2. My brother worksin a shop.
3. Lucy livesin Beijing.
4 .His parentslive in Scotland.
5.It rainsa lot in summer.
總結：一般現在時人稱和動詞的變化，注意人稱三單和動詞三單情況
Group2 一般現在時
一般現在時經常用一些頻度副詞來表示經常性的行為
1.She alwaysgets up early.
2.I nevereat lunch.
3.We oftengo shopping at weekends.
4.Mike usuallyplays football on playground.
02一般過去時
Group3
5.I cleanmy teeth every morning.
This morning I cleanedmy teeth.
6.Ted workedin a bank last year.
7.Yesterdayit rained all morning.
8.We enjoyedthe party last night.
9.The party finishedat midnight.
10.I usually get upearly, but this morning I got up at 9 o 』clock.
11.We dida lot of work yesterday. do
12.She wentto the cinema last week. go
13.Jack cameinto the room, and sat down. Come sit
通過觀察可以發現動詞的變化，以及所跟的時間都是過去的某個時間，但是變化規則不一樣，這是難點。
總結1：過去時的陳述句中所有人稱後的動詞形式都一樣
總結2：規則動詞後直接加ed
dance —danced
stay —stayed
work —worked
clean — cleaned
start —started
need —needed
總結3:不規則動詞
練一練，請畫出下面句子的過去時
1.Last week, I went to Beijing. 上周，我和我的父母去了北京。
2. I stayed there for three days. 我在那裡待了三天。
3. I saw many places of interest. And I ate Beijing Duck, it was delicious!
我看到了許多名勝古蹟。並且我吃了北京烤鴨，它很好吃!
4. I had a good time. I'll go there again. 我玩得很開心。我還要去那裡。
5. Danny came to my house yesterday. Danny昨天來我家了。
03一般過去時句式變換
觀察變化，對比學習
1. They work hard. (將句子改為一般過去時)
They workedhard.
2. Does he practice the violin? (將句子改為一般過去時)
Didhe practice the violin?
3. Do you travel by air? (將句子改為一般過去時)

5. He loves his friend very much. (將句子改為一般過去時)

總結時態的句式變換
總結：過去時就是難在了動詞變過去式比較複雜，而且數量龐大，需要足夠的時間去記憶和消化吸收。
