We use if t talk abut the result f a pssible actin. We make sentences with if like this:
Presentatin
Tips: We put a cmma after the if-clause when it is the first part f a sentence.
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 hme.如果下雨我们就待在家里。
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 ging t表示将来，而应该用shall, will。e.g. If yu leave nw, yu 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。e.g. If it rains tmrrw, 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 cmes 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。
