Work out the rule
When we use a conditional sentence to talk about something that will certainly happen, both verbs should be in( the simple present tense/the simple future tense).
Things to remember
We can also put the if-clause after the main clause.
Salt disappears if you put it into water.
Read these if-clauses and draw lines to match them with the results.
A1
Exercise on book
What happens if you take a fish out of water
Are you sure
It dies.
Of course I’m sure.
If you take a fish out of water, it dies.
In pairs, make conversations about the sentences in A1 on page 103.
A2
S1: What happens if you switch off the lamp
S2: The room becomes dark.
S1: Are you sure
S2: Of course, I’m sure. If you switch
off the lamp, the room becomes dark.

如果你不努力，你就不会成功。
= Unless you work hard, you will not succeed.
除非你努力工作，否则你不会成功。
unless意为“除非”，和if…not(如果……不……)的意思相近，且两个结构通常可以互换使用。
在unless引导的从句里，通常用现在时表示将来。
I’ll not attend the party unless he invites me.
除非他邀请我，否则我不会参加这个派对。
Unless you have good idea, I’ll take his advice.
除非你有更好的主意，否则我将采取他的建议。
注意：unless用于引出某事发生或成立所必需的条件。如：
除非你能做到，否则不要随便许诺。
You should not promise anything unless you can do it.
