The Value of Tears

Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. Tears leave you embarrassed and without energy. Still, crying is a fact of life, and your tears are very useful. Even when you’re not crying, they make a film over the eye’s surface.  小题1:

When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “People worry about showing their emotions(情绪), afraid that once they lose control they’ll never get it back.”  小题2: After we cry, the  feelings that caused the tears often disappear.

Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling — shock, anger, fear, or sadness— is being held back.

But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry.  小题3: Patients practice crying just to become used to expressing emotions. She suggests safe, private places to cry, like under the bedcovers or in the car. Crying is a way of ease tension, but people don’t like it when others cry because it makes them tense.小题4: And they’ll do just about anything to make you stop.

In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion.  小题5:You should also act out the whole situation again and be as noisy and angry as you like. It will help you feel better. “And,” she adds, “Once your tears have taken away the stress, you can begin to think calmly of ways to deal with the problem.”

Tears are a sign of our ability to feel. If you find yourself near someone crying, deal with it. And never be afraid to cry yourself.

A.They too may be holding back a need to cry.

B.They cry for different reasons.

C.She gives crying exercises.

D.It contains a chemical against infection(炎症).E. The fact is no emotion lasts forever.

F. It forms in response to the stress on the surface of the eye.

G. But once you’re safely behind closed doors, don’t just cry.

若在一个正弦(或非正弦)信号周期内取若干个点的值,取点的多少以能恢复原信号为依据,再将每个点的值用若干位二进制数码表示,这就是用数字量表示模拟量的方法。将模拟量转换为数字信号的介质为模/数转换器(ADC)。数字影像则是将模拟影像分解成有限个小区域,每个小区域中影像密度的平均值用一个整数表示。也就是说,数字化图像是由许多不同密度的点组成的,每个点内的密度是一均值。图像矩阵是一个整数值的二维数组。图像矩阵的大小一般根据具体的应用和成像系统的容量决定,一幅图像中包含的像素数目等于图像矩阵行与列数的乘积。

512×512表示()

A.矩阵

B.像素值

C.图像的灰阶数
