A moment's drilling by the dentist may make us nervous and upset. Many of us cannot stand pain.

To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle"— a shot of novocaine (奴佛卡因) -that deadens the nerves around the tooth.

Now it' s true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves— we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.

But there is a way to handle pain. Look at the Indian fakir(行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain; This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.

The big thing in withstanding pain is our attitude toward it. If the dentist says, "This will hurt a little, it helps us to accept the pain. By staying relaxed,' and by treating the pain as an interesting sensation, we' can handle the pain without falling apart. After all; although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.

26. The passage is mainly about______.

A) how to stiffer pain

B) how to avoid pain

C) how to handle pain

D) how to stop pain

参考答案和解析
正确答案:C
答案:C
[试题分析]文章主旨题。
[详细解答]文章从以牙医用奴佛卡因来帮助病人减轻疼痛来开头,接下来又用印度行僧在胳膊上插上针来镇痛的例子说了人类对付疼痛的历史,最后仍然是有关对付疼痛的,指出人感觉疼痛的程度与态度有关。可见,全篇的内容都与人类对付疼痛有关,正确答案应为C。

  • 第2题:

    收发两端之间的传输距离为1000km,信号在媒体上的传播速率为200000km/s,数据长度为1000bit,数据发送速率为1Gbit/s,其发送时延为(),传播时延为()。

    A.1us,5ms

    B.10us,5ms

    C.10us,50ms

    D.100us,50ms


    (1)发送时延为100s传播时延为5ms。(2)发送时延为lμs传播时延为5ms. 结论:若数据长度大而发送速率低则在总的时延中发送时延往往大于传播时延。但若数据长度短而发送速率高则传播时延又可能是总时延中的主要成分。 (1)发送时延=107bit/(100×103b/s)=100s(2)发送时延=103bit/(109b/s)=1μs两者传播时延都为=l000×103m/(2×108m/s)=5ms

    A.U=US?R×I
    B.U=US+R×I
    C.U=?US?R×I
    D.U=?US+R×I

    答案:B
    解析:
    电压与电流为非关联参考方向,在电压与电流的表达式中使用负号。因此,端口电压U=US?R×(?I)=US+R×I。该题还可以从电压、电流的的参考方向与实际方向的关系这一角度考查。出题陷阱:二端口的电压方向与电压方向一致,因此C、D错误;参考电流方向与参考电压方向不一致,因此A错误。部分同学误选择A,未能理解非关联参考方向的意义。
