1课文 We looked for them,but we could not find them all.
我们虽然找了,但没有把它们全部找到.
我写的we had looked for ,but couldn't find them all.不是说在过去中最早发生的一个行为要用过去完成时吗?为什么课文没有用
2课文We both tried to get the coins,but it was too late.
我们俩都试图把这两枚硬币拿出来,但太迟了.
我写的we tried to get the two coins,but too late可以吗
3课文'Tommy's been to the toilet three times this morning,
“今天上午汤米去了3次厕所了,
我写的tommy went to toliet three times this morning可以吗,用过去式不好吗,为什么要用完成时?

1、不可以 .因为本句表达的是“我们找了”,接下来强调look for 动作发生的结果是“没有全部找到”,很显然两个动作是连贯的.所以,不用过去完成时.又如：I looked at the blackboard, but I could see nothing.
2、不可以 .因为but前后连接的是两个表达完整的句子,but前面是指出“我们俩试图把硬币拿出来”,后面是对“‘拿硬币’这件事太迟了”作出说明,况且主语不同,所以不能省略.例如：He wanted to cross the road, but it was too late, the traffic light turned red.
3、用完成时.强调动作的反复发生.例如：He has been to Beijing three times.
