问题 单项选择题

硫氮酮的作用是()

A.扩张小静脉

B.扩张小动脉

C.二者均有

D.二者均无

答案

参考答案:B

解析:

6版内科学P174(5版P165)《慢性心衰的治疗》中强调硝酸甘油、硝酸异山梨酯(消心痛)的作用机理是扩张小静脉、降低前负荷。但在6版内科学P279(5版P290)《心绞痛》治疗中,又强调其作用机理为扩张小动、静脉,减低前后负荷及扩张冠状血管。且该知识点经常考。查阅新版《7年制内科学教材》,该书中作用机理为扩张小动脉和静脉,但扩静脉的作用超过扩动脉。129题给出的答案为C (既能扩张小静脉,又能扩张小动脉),答案请略酌。

Much meaning can be conveyed, clearly, with our eyes, so it is often said that eyes can speak.

Do you have such kind of experience? In a bus you may look at a stranger, but not too long. And if he is sensing that he is being stared at, he may feel uncomfortable.

The same is in daily life. If you are looked at for more than necessary, you will look at yourself up and down to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward other’s stare at you that way. Eyes do speak, right?

Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to stare at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to avert his gaze, his intentions are obvious. That is, he wishes to attract her attention, to make her understand that he is admiring her.

However, the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time; in order to make sure that the listener does pay attention to hat the former is speaking, to tell him that he is attentive. 

If a speaker looks at you continuously when speaking, as if he tries to dominate you, you will feel disconcerted. A poor liar usually expose s himself by looking too long at the victim, since he believes the false ides that to look straight in the eye is a sign of honest communication.

In fact, continuous eye contact is confined to lovers only, who will enjoy looking at each other tenderly for a long time, to show affection that words cannot express.

Evidently, eye contact should be done according to the relationship between two people and specific situation.
