学语法不求人 一看就懂（一般过去时）
初学者学语法难度较大，但是可以另辟蹊径，通过观察来学习语法也不失为一个好办法，只要前面学过了一般现在时，现在进行时等语法知识，这样就可以循序渐进，就会为后面进一步学习其它语法知识打下了一定的基础。
今天学习一般过去时，这一时态比较复杂，因为涉及到太多的动词变形，有规则动词和不规则动词，需要大量的记忆。不过只要掌握了一般过去时的结构特点，再去记忆一些细节也就只是时间的问题了。
通过比较来学习一般过去时，两者之间形成对比，特点各异，就可以很快掌握这一时态的结构和特点，前提是要认真观察，一起来学习新的内容。
先读一组一般现在时，复习和总结这一时态的特点
Group1 一般现在时
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.
总结：一般现在时人称和动词的变化，注意人称三单和动词三单情况
Group2 一般现在时
一般现在时经常用一些频度副词来表示经常性的行为
1.She alwaysgets up early.
2.I nevereat lunch.
3.We oftengo shopping at weekends.
4.Mike usuallyplays football on playground.
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
通过观察可以发现动词的变化，以及所跟的时间都是过去的某个时间，但是变化规则不一样，这是难点。
总结1：过去时的陈述句中所有人称后的动词形式都一样
总结2：规则动词后直接加ed
dance —danced
stay —stayed
work —worked
clean — cleaned
start —started
need —needed
总结3:不规则动词
练一练，请画出下面句子的过去时
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. 我在那里待了三天。
3. I saw many places of interest. And I ate Beijing Duck, it was delicious!
我看到了许多名胜古迹。并且我吃了北京烤鸭，它很好吃!
4. I had a good time. I"ll go there again. 我玩得很开心。我还要去那里。
5. Danny came to my house yesterday. Danny昨天来我家了。
观察变化，对比学习
1. They work hard. (将句子改为一般过去时)
They workedhard.
2. Does he practice the violin? (将句子改为一般过去时)
Didhe practice the violin?
3. Do you travel by air? (将句子改为一般过去时)

4. The boy doesn"t try his best. (将句子改为一般过去时)

5. He loves his friend very much. (将句子改为一般过去时)

总结时态的句式变换
总结：过去时就是难在了动词变过去式比较复杂，而且数量庞大，需要足够的时间去记忆和消化吸收。
