D

The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap(间隙)with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic udner discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

Nurses and other care-geivers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be expericencing. Nurses should recognize their own personal and cultural construction of silence so that a patient’s silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

What does the author advise nurses to do about silence?()

A. Let it continue as the patient pleases.

B. Break it while treating patients.

C. Evaluate its harm to patients.

D. Make use of its healing effects.

阅读下列材料,然后回答问题.

物理学中把具有流动性的液体和气体统称为流体.当流体处于流动状态时,其内部各处的压强有什么规律呢?

小明同学将如图甲所示的玻璃管装置按到水流稳定的自来水管上,当水在玻璃管中流

动时,可看到两个竖直管中液面的高度并不相同.从图中可以看出在A、B两处管的粗细不同,因而A处流速小,B处流速大,可见流体的压强与流速之间有着一定的关系.

接着,小明又自制了一个飞机机翼模型(如图),将其固定在托盘测力计上,在机翼模型的正前方用电扇迎面吹风,来模拟飞机飞行时的气流,比较机翼上下方气流压强的大小,进一步验证了上面的关系.

(1)由图甲所示的实验,可以得出流体的压强与流速之间有什么关系?答:                  

(2)在图乙所示的实验中,电扇转动后,托盘测力计的示数发牛了什么变化?答:             

(3)下列四种情形中,哪几种情形能够运上述的实验规律进行解释        

A.乒乓球运动员拉出的弧圈球能急速旋转而下沉

B.将氢气球放手后,它会漂向空中

C.直升飞机能够停在空中一定高度处

D.船舶航行时应避免两艘靠近的船并排前进
