企业短期供给曲线

答案

参考答案:

是指在AVC曲线以上的MC曲线部分。因为,在完全竞争条件下,企业为了追求最大利润,必定要按P=MC的条件决定自己的产量,这样,企业的产量总是随着市场价格的变化而沿着MC曲线而增减,直到市场价格低于AVC曲线的最低点时,企业就要停产。所以,在AVC曲线以上的MC曲线部分就是企业的短期供给曲线。

Too many people want others to be their friends, but they don’t give friendship back. This is why some friendships don’t last long .To have a friend, you must learn to be a good friend. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

Honesty is where good friendship starts. Friends must be able to trust(信任)one another. They should tell the truth. If you aren’t honest, you’ll lose your friend’s trust. (1)A study shows that those who often tell lies can’t get on well with the other people. Good friends always depend on one to speak and act honestly.

Generosity makes a friendship grow well. It means sharing. You do not have to give your lunch money or your clothes. Naturally you want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.

Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend, you must listen and understand.(2)Try to put yourself in your friend’s place, or you can’t understand the problem better.

Now, do you know what you should do if you want to be a good friend and keep your friends?
