英语中表达“如果”除了能用if,without,provided,presumably之外，还能有什么方式？最好能有例句。多谢

MS 有很多啊
用词来带动的 比如
in case
In case she comes back, let me know immediately.
on condition (that)
You can use the bicycle on condition that you return it tomorrow.
以上例句来自网络
还有在句子里自然形成的
比如 No pains, no gains. 可以翻译成 “如果不努力，就不会有收获。”

虚拟语气中的should
Let me know if you should hear more news.万一听到更多消息，请告诉我。

in case of
In case of rain they can't go.万一下雨，他们就不能去了。

provided （that）
Provided that circumstances permit, we shall hold the meeting next week.只要情况允许，我们下周将举行会议。

on condition that
I will go abroad on condition that my husband goes with me.如果我丈夫能和我一起去, 我就出国。

in case，on condition that.用法和if一样啊，不用举例了吧。
