1. Li Lei put his book down and help me pick up my pen.
2. I get up late this morning,so I missed the NBA game on TV.
3. Sorry,Mr. Yang,I forget to do my homework yesterday.
4. My grandfather often tell us stories under the tree when we were young.

8. The man run away when he saw the policeman.

2. got
3. forgot
4. told
5. stayed
6. showed
7. taught
8. ran
9. arrived; set
10. goes; went

本题主要考查一般过去时和一般现在时的动词形式运用。一般过去时用于描述过去发生的动作，常搭配yesterday, last Friday, last year, this morning等过去时间标志词，或根据语境判断动作发生在过去；一般现在时用于经常性、习惯性动作，常搭配usually等标志词，主语为第三人称单数时动词需变第三人称单数形式。具体如下：
1. 前半句put为过去式，and连接并列动作，故用help的过去式helped；
2. this morning和后半句missed提示用一般过去时，get的过去式为got；
3. yesterday提示用一般过去时，forget的过去式为forgot；
4. when we were young提示用一般过去时，tell的过去式为told；
5. 对话语境为过去的中秋节，wasn't提示用一般过去时，stay的过去式为stayed；
6. last Friday提示用一般过去时，show的过去式为showed；
7. last year提示用一般过去时，teach的过去式为taught；
8. saw提示用一般过去时，run的过去式为ran；
9. yesterday afternoon提示用一般过去时，arrive的过去式为arrived，set的过去式与原形一致为set；
10. usually提示第一空用一般现在时，主语my uncle是第三人称单数，故go变goes；last month提示第二空用一般过去时，go的过去式为went。

三、句型转换,每空一词。
1. Li Mei did her homework at home last weekend.改为否定句
Li Mei her homework at home last weekend.
2. The girl took the sick cat to the animal centre.改为一般疑问句并作肯定回答
— the girl the sick cat to the animal centre?
—,she .
3. I went to Jiuzhaigou with my family last summer.对画线部分提问
you to Jiuzhaigou with your family?
4. I worked in Hangzhou ten years ago.对画线部分提问
you ten years ago?
5. Chen Lan's mother watches TV every evening.用last night改写句子
Chen Lan's mother last night.

1. didn't; do
2. Did; take; Yes; did
3. When; did; go
4. Where; did; work
5. watched; TV

本题考查一般过去时的句型转换，需掌握一般过去时的否定句、一般疑问句、特殊疑问句的变法，以及时态转换：
1. 一般过去时实义动词作谓语的句子变否定句，需借助助动词didn't，后面动词用原形，原句中did是do的过去式，所以填didn't do。
2. 一般过去时实义动词作谓语的句子变一般疑问句，需借助助动词Did放句首，动词还原为原形；肯定回答用Yes, 主语+did。
3. 对时间状语提问用When，一般过去时需借助助动词did，动词还原为原形go。
4. 对地点状语提问用Where，一般过去时需借助助动词did，动词还原为原形work。
5. last night是过去时间，句子要变为一般过去时，watches的过去式是watched，所以填watched TV。
