Last week she wasn't feeling very well.
An old lady was waiting for the bus.
The sun was setting.
Birds were singing in the trees.
When I saw him, he had been ill for a month.
He couldn't see anyone.The thieves had gone.
He showed me the books he had bought.
She explained what had happened.
He was eighteen. In two years he would be twenty.
I thought you would wait for me.
Did you know Mary would come?
He assured me that he would support us.
过去将来时除了使用would以外，还可以使用was/were going to表示：
I was going to the library when you called me.
a. He told me that he was writing a novel.
She said that she had got everything ready.
Mother asked when I would be back.
b. He said he was calling from the airport.(比较: I'm calling from the airport.)
She said she just got my fax.(比较: I've got your fax.)
I said I'd be with them right away.(比较: I'll be with you right away.)
Every Saturday they would go to the club.
Sometimes we would sit together chatting.
The door wouldn't open.
The car wouldn't start.
