写作题

阅读下面的短文,然后按照要求写一篇150个词左右的英语短文。

Happiness cannot last forever and it may be due to everything from the weather to the size of your bank account.

We’re not suggesting that you can reach a permanent state called “happiness” and remain there. But there are many ways to get out of the path of anxiety, anger and sadness into a state of happiness once or even several throughout the day.

Practice mindfulness. Be in the moment. Instead of worrying about your family, focus on the here and now----the food, the company, and the conversation.

Laugh out loud. Researchers at the University of California Irvine, tested 16 men who all agreed they thought a certain videotape was funny. Half were told three days in advance they would watch it. They started experiencing biological changes right away. When they actually watched the video, their levels of stress hormones (激素) dropped significantly.

Make a list. There’s nothing like writing down your tasks to help you organize your thoughts and calm your anxiety. Checking off each item provides a great sense of fulfillment.
