题型:完形填空

Ideally speaking, criticism(批评) is the act of making comments on someone or something with the purpose of improving products or service. However in daily life, you will meet some people criticizing with the negative purposes,

What should you do when you are being criticized? Actually, you should take it positively. It is possible that the person who criticizes you has rightly drawn your attention to something which needs improving. If this is the case, be thankful to the person because he is helping you to know where to improve.

However, there is also a chance that the criticism is being done just to make you sad. So if necessary, ask one of your friends or workmates what he thinks of this criticism. If the criticism is really meant to hurt you, pay no attention to it and don’t allow it to disturb your peace of mind.

When you are criticizing someone or something, always remember that negative criticism causes negative energy, so try to criticize in a positive manner. Do not become the “full stop” for someone’s creativity

Whenever you are about to criticize, ask yourself whether your purpose is to help the person or if you are just going to spread negativity which will damage someone’s creative skills.

If you really want to criticize someone, do it in an encouraging way. Try to give your comments in this way so that he can put your suggestions into corrective(改正的) actions. What’s more, you should remember the fact that complaining is taking criticism to the next level which is even more damaging and dangerous. So try to remain inside the limits of criticism instead of complaining.
