青少年应在消除废旧电池（重金属）对人类的危害中做些什么？

答案

废电池的危害：废电池里含有大量重金属汞、镉、锰、铅等．当废电池日晒雨淋表面皮层锈蚀了，其中的成分就会渗透到土壤和地下水，人们一旦食用受污染的土地生产的农作物或是喝了受污染了的水，这些有毒的重金属就会进入人的体内，慢慢的沉积下来，对人类健康造成极大的威胁．据测量一节一号电池烂在土壤里，可以使 一平方米 土地失去利用价值；一个扣钮电池可以污染 60 万升水，相当于一个人一生的饮水量．控制废电池危害的根本措施是禁止生产和销售危害性大的电池，特别是含汞或 镉的电池，大力开展无公害的环保型电池电池，对于废旧电池，则应当及时回收，集中进行安全处理．

故答案为：（1）认识废旧电池的危害；

（2）从我做起，从身边事做起，不乱扔废旧电池；

（3）向周围的人宣传将废旧电池放入专门的收集箱内．

In the following passage, there are 25 blanks representing words that are missing from the context. You are to put back in each of the blanks with the missing word. Write your answers on the ANSWER SHEET. The time for this section is 25 minutes.

The decision which faces (2) is not one of practical action: of course he will try to throw this (3) into the scale, and that weight, if he is a writer or (4) a painter of genius, may have its effect. For the novelist—in our society the only artist who has a mass audience and at the same time effective economic control of the means of addressing (5) —the hope of some decisive influence is a reasonable (6) . For him, since he takes of all artists (7) is probably the largest portion of his culture as material, there is no (8) escape from the necessity for treating the content of his work seriously than (9) is for the social psychologist he is coming so closely to resemble. The dichotomy which people have tried to establish between artistic proficiency and (10) content is becoming unbearable to almost all sensitive minds. I doubt if it has ever been real— we might have admired Shelley as (11) if he had been indifferent to such things as war and tyranny, though I doubt it; certainly (12) he been indifferent we should never have been led by (13) .
There is no Hippocratic oath in literature, and I am not attempting to draw (14) up. As far as I am concerned, the artist is a human being writ large and his (15) are the ethics of any human being. Perhaps I can best illustrate (16) seems to me the new (17) of those duties of assertion and refusal from one writer, and I do not (18) it is without significance that this (19) projects the whole situation of choice into a scientific parable, the (20) of a pestilence: a (21) many human (22) are called to fight against, called not by any supernatural (23) but by the simple fact that the fight against a plague is (24) like a biological human (25) .
