后鼻腔出血可用__________________________做后鼻腔填塞术，术

In an American classroom, a Chinese girl was asked to answer a question. She stood up and smiled, without making any sound. The American teacher looked at himself and didn’t see anything funny. So he asked her the question again. The girl just smiled but said nothing. The teacher was angry. He didn’t know that the girl smiled to cover her embarrassment（尴尬）because she wasn’t able to answer the question.

In a dining room in Beijing, an Englishman was careless and dropped a plate. The Chinese who had seen this began to laugh. The Englishman felt uncomfortable and even got angry. “They are laughing at me,” he thought. In fact the Chinese laughed not at the Englishman or his bad luck—whether he is a foreigner or a Chinese. The smile or laughter has several feelings: don’t take it so seriously; laugh it off, it’s nothing; such things can happen to any of us.

Do you have any special ways you use to help you do better on a test? How well you do is often a matter of how well prepared you are. Here are some ways to make sure you’re at your best on test days.

Go to bed early. The night before a test is not the time to stay up watching TV. You have tio be awake for the test day.

小题2:Make sure you have two pencils and anything else you were asked to bring.

小题3:Make sure that the number on your answer sheet matches the number of the question.

小题5:Make sure you allow yourself enough time to answer every question and go back and check your answers. Don’t spend too much time on any difficult question. Pass it and come back to it later.
