自己写了一个英语句子，请高手帮忙看有什么语法错误没。或者有什么更好的表达方式。谢谢了~~

1.confront with把with去掉，它是及物动词

2.are very important改为is very important，how to do 是句子做主语了，单数。

3.honest建议改成honestly

4.touch应该是三单形式

感觉底线的翻译有点怪怪的感觉，直接bottom line 就可以了

5. you must bravely to beat back把to 去掉

修改一下：We may confront with all sorts of difficulties in our life, but it is very important to know
how to deal with social relations. 解释：all sorts of 后用复数； 后一句用it is 结构更通顺。
First, it must be very hurtful to cheat or betray your friends, so we should treat each other honestly.解释：honestly 修饰treat 应用副词形式。
Second, we should go to learn patience, but patience is not cowardice. If someone touches the bottom of your line, you must beat back bravely.解释：someone 应该用单数形式；bravely 修饰动词beat back 用副词形式。

We'll be challenged by various kinds of difficulties during our whole life, and how to maintain good social relationships with others is one of them.Following are my understandings.
On the one hand, we ought to be honest and faithful. People prefer to making friends with sincere persons; nobody will feel happy when being cheated or betrayed. Honesty and sincerity are of fundamental importance in social communication.
On the other hand, we should also be patient. A patient person may bring comfort and ease to others. It is helpful to promote social relations. However, patience doesn't mean weakness.When others reach beyond your bottom line, the only thing you need to do is to strike back bravely.
