If you stay calm and say sorry, it will help.
If I go there, I will try all the delicious local food.
If I visit China this year, I’ll go to the park with you.
Match the two parts to make sentences.

If 条件句
if 从句是英语常用的句型，核心规则是 “主将从现” 。
基础规则：if 引导的条件状语从句用 一般现在时 ，主句用一般将来时（will + 动词原形 ） 。即“如果（现在/未来的条件）满足，就会（未来发生的结果）”
例如：If it rains, we will stay at home. 如果下雨，我们就会待在家。
（条件 “下雨” 是未来可能发生的，用一般现在时；结果 “待在家” 是条件满足后未来的动作，用 will + 动词原形）

2. difficulty n. 困难；难题
常用作可数名词，其复数形式是difficulties。
（1）have difficulty (in) doing sth. 意为“做某事有困难”，其中的介词in 可以省略，此时的difficulty 是不可数名词，不使用复数形式。
例句：She had great difficulty finding a job. 她找工作及其困难。
（2）difficulty 的形容词形式是difficult，意为“困难的”。
例句：The reading exercise was very difficult for most of the children. 这个阅读训练对很多孩子来说都很难。
3. If I have good news, I’ll call you right away. 如果我有好消息的话，我会立刻给你打电话。
right away “立刻、马上”
修饰动词，可放句末或句首。

例句：You should go to see a doctor right away. 你应该立马去看医生。
4. If you think you can come, drop me a line . 如果你认为你能来的话，给我留言。
