Oranges are grown on these hills .这些小山上种有橘子树.
2.一般过去时：
He was born in Shanghai .他是在上海出生的.
They were pleased by these words .听了这些话他们很高兴.
3.一般将来时：

Shall we be invitde to the party 要邀请我们参加晚吗?
4.现在进行时：

These problems are being discussed.这些问题正在讨论.
5.现在完成时：

Has anybody been hurt?有谁受伤了吗?
6.过去进行时：

A party was being held in the next room.隔壁房间正在开舞会.
7.过去完成时：

I didn't know he had been fired.我不知道他被解雇了.
条件句
一种是真实条件句,表示一个可能出现的情况：
I'll help him if he asks me.如果他向我提出,我可以帮助他.
另一种是虚拟条件句,表示一种假象的情况或实现的可能性不大的情况.
这种句子是虚拟语气条件句.
1.谈过去的情况：条件从句（had+过去分词）；主句（would have+过去分词）
If he had asked me,I would have helpde him.如果他向我提出了,我就帮助他.（但他没向我提出）
2.谈现在或将来情况：条件从句（过去式）；主句（would +动词原形）
If I had the money,I would travel round the world.(但我没有钱）
动词为be时,多用were这个形式：If I were you,I would accept the job.我要是你,就会接受这份工作.
有时if可以省略,这是后面要用倒装语序：Wewe I in your position,I would stay.我要是处在你的地位,我会留下.
