1. She mailed/mails the letter as soon as she bought/buys a stamp.
答案：
(答案→)1. She mailed/mails the letter as soon as she bought/buys a stamp.
解析：
1. 本题的含义为她一买到邮票，就把信件邮寄给我，as soon as后引导时间状语从句她买邮票she bought a stamp，主句为她把信件邮寄给我She mailed the letter ，故本句可连成She mailed/mails the letter as soon as she bought/buys a stamp.
2. 改为否定句，本题为一般动词使用didn’t后跟动词原形use构成否定句，故本题的答案为neg. They didn’t use to live in the countryside.
对地点提问的用where 后跟一般疑问句，故本题所写的问题可以为Q: Where did they use to live?
3. 对于做某事的方式提问的可用疑问词how，后跟一般疑问句，本题使用助动词did后跟动词原形improve，故本题的答案为How did he improve his English?
4. 含有助动词has改为否定句在其后加not，故本题的答案为She hasn’t finished that report yet.
5. 本句的含义为直到你告诉我发生了什么事我才离开这儿，主句应该写成我们将离开的否定形式We won’t leave here，until后跟的从句不变，故本题可写成We won’t leave here until you tell me what has happened.
6. would rather……than表示宁愿做什么，而不愿做什么的含义，两者后跟动词原形乘飞机take a plane和坐火车旅行travel by train，故本题可写成I would rather take a plane than travel by train.
7. 本题可以用if引导的条件句来写，如果工人们工资不上涨，他们将继续罢工，故本题可写成If the workers don’t get a pay rise, they will go on strike.
