1. I will ask the teacher for help if I don’t understand.

you may feel sad about it

A We use if to talk about the result of a possible action. We make sentences with if like this:
If-clause (simple present tense) Main clause
(will/may/might/…+infinitive)
If you are a football fan, you will not want to miss this week’s programme.
If you are an animal-lover, you may feel sad about it.
If you enjoy solving mysteries, you might like this film.
TIP: We put a comma after the if-clause when it is the first part of
a sentence.
Using if
If hunters catch a giant panda, they will kill it for its fur.
The dangers that giant pandas are facing:
If farmers cut down trees and forests, giant pandas will have nowhere to live.
= They will kill it for its fur if hunters catch a giant panda.
= Giant pandas will have nowhere to live if farmers cut down trees and forests.

条件状语从句
条件状语从句主要由if或unless引导:
if条件句
1) if条件句:条件句用于陈述语气,表示
假设的情况可能发生,其中 if 是“如果”的意思。
e.g. If it rains, we will stay at home.
如果下雨我们就待在家里。
Grammar rules
2) 用法:
(1)条件状语从句通常由连词if引导,意为“如果、假如”,主句不能用be going to表示将来,而应该用shall, will。
e.g. If you leave now, you will never regret it.
如果你现在离开,你永远都不会后悔。
(2)if “如果”,引导条件状语从句,主句用一般将来时,从句则用一般现在时。(主将从现)
e.g. If it rains tomorrow, I shan’t climb the hills.
如果明天下雨,我就不爬山了。
(3)主句是祈使句或含有情态动词,从句也用一般现在时。
e.g. Please call me if he comes next Sunday.
如果他下周日过来请打电话给我。
注意: 宾语从句中的if与条件状语从句if的区别。宾语从句中的if “是否”相当于 whether, 引导宾语从句, 时态需根据语境确定。如果主句用一般现在时, 从句可以根据具体情况选用时态, 如果主句用一般过去时, 从句必须用过去时的某种形式。
if引导条件状语从句
主句 if 从句
①一般将来时
②情态动词 + 动词原形
③祈使句
一般现在时
(动词用原形或三单)
