5、n.如果你考试不及格，你会让他失望的。注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去 完成时。What would happen if there were no water?如果没有水会怎样？unless的意思是”如果不，除非o可与if. not互换。You will fail in English unless you work hard.你英语考试会不及格的，除非你更加努力。You will fail to arrive there in time unless you start earlier.如果你不早点动身，你就不能及时赶到那儿。Unless it

6、 rains, the game will be played.除非下雨，比赛将照常进行。3. as /so long as引导的条件状语从句as /so long as的意思是只要So long as youre happy, I will be happy.只要你高兴，我就高兴。You may borrow my book as long as you keep it clean.只要你保持书的清洁，你就可以把我的书借去。4. once引导的条件状语从句once引导的条件状语从句，意为“一旦就，从句可置于主句前或后。Once you begin, never stop. 一旦开始，就绝不要
