“吸毒一口,落入虎口”.青少年对待毒品应持有的态度是(    )

A.坚决拒绝,绝不沾染

B.少量吸毒,无关紧要

C.朋友要吸毒,不加劝阻

D.仅吸一口,绝不再吸

答案

答案:A

题目分析:毒品对中枢神经系统和周围神经系统都有很大的损害,可产生异常的兴奋、抑制等作用,出现一系列神经、精神症状,如失眠、烦躁、惊厥、麻痹、记忆力下降、主动性降低、性格孤僻、意志消沉、周围神经炎等,对心血管系统、呼吸系统、消化系统和生殖系统等都会造成严重的危害,毒品具有很强的成瘾性,一旦沾染,很难戒除,严重危害人体身心健康,危害社会,一而再、再而三地吸毒形成了对毒品的依赖性之后,吸毒后的快感会不断递减,因此,为了达到与原来同样的刺激强度,吸毒者必须加大剂量,如果毒品用量过度会引起吸食者猝死,后果不堪设想,因此我们都要杜绝毒品,尤其是青少年,要坚决远离毒品,坚决杜绝“第一口”,吸毒往往是从第一口开始的,一旦开始,就会成瘾,故选A。

An awkward-looking character such as Cyrano de Bergerac might sniff at the suggestion, but recent scientific research shows beauty, brains and brawn may in fact all be allied, writes Dr Raj Persaud.

(46) Psychologists have concluded that we may be drawn to the stereotypically attractive because of what their faces reveal about their intelligence and success in later life. In American, research led by Professor Leslie Zebrowitz, of Brandeis University, has shown an association between facial attractive and IQ. Strangers briefly exposed to a target’s face were able to correctly judge intelligence at levels significantly better than chance.

The same team also researched how a person’s attractiveness might bear relation to their intelligence. They found that good-looking people did better in IQ tests as they aged. (47) Their research sought to prove that how a person perceived himself and was perceived by others predicted how intelligent he apparently became more accurately than his past intelligence. (48) Perhaps because the more attractive people were treated as more intelligent, they ended up having more stimulating and, therefore, intelligence-enhancing lives.

Does this mean that your face really could be your destiny Sociologists Dr Ulrich Mueller and Dr Allan Mazur, of the University of Marburg in Germany, recently analyzed the final year photographs of the 1950 graduates of West Point in the United States. Dominant facial appearances turned out to be a consistent predictor of later-rank attainment:

Again, they believed there could be a self-fulfilling effect. (49) Because some men looked more authoritative, they naturally drew respect and obedience from others which, in turn, assisted their rise through the ranks.

A team at the Royal College of Surgeons in Dublin has been investigating the sensitive subject of links between physical and mental abnormalities. Led by Doctors Robin Hennessy and John Waddington, the team used a new laser surface-scanning technique to make a 3-D analysis of how facial shape might vary with brain structure. Their findings showed that in early fetal life, brain and face development are intimately connected. From this they concluded that abnormalities in brain elaboration probably also affect face development.

This, according to them, explains the striking facial features of some one with Down’s syndrome. (50) Using similar techniques, the team also demonstrated how other disorders linked to brain aberrations could be associated with facial alterations.

So the very latest scientific research suggests that nobody should try to look too obviously different from average.
