In our daily life，we dislike mistakes，and sometimes we're even afraid of them.But in fact，mistakes are really good in some ways. ①Here are               reasons.
   Firstly，when we make mistakes，we're growing.It is clear that we are trying new things. ②If we never try            ，how can we improve and develop？The simple answer is "We can't".Almost everything we see in our real world is the result of someone trying something new.
   ③Secondly，when we make mistakes，              .Edison failed 10，000 times before he invented the light bulb，but he himself didn't think so.He said he just learned 10，000 things.
   At last，when we make a mistake，we are much closer to success.Because we will try many times before we succeed.Every time we make a mistake，we'll have one more chance to succeed next time.There is an old saying："If you're not making mistakes，you're not trying hard enough."
   Let's go ahead and face mistakes，then we can grow，learn and succeed.
