参考答案:
1.A 答案解析:看第2题的四个选项可以断定这里指食人鱼是什么样的杀手。应当选择具有“作为”含义的词。选项A是正确的:作为可怕的杀手。
2.B答案解析:Killer杀手,murderer凶手。二者的区别在于前者泛指杀人,后者强调有预谋的行凶。故,B答案正确
3.D答案解析:Tell告诉,say说,describe描述,portray描绘。文中have been表明是被动语态,应选择过去分词;根据上下文,这种鱼已被描绘成致命的食肉动物。选项D是正确的。
4.C答案解析:表示“来自于哪儿”应用介词from。此处意为来自圣安德鲁斯大学的老师。选项c是正确的
5.B答案解析:解析:根据上下文:食人鱼组成巨大的群体并不是为了猎取,而是为了自我保护以抵御其他的捕猎者。因此,这里应选用具有“它们自己”含义的词。选项B是正确的。
6.D答案解析:Able能够,应与be连用;be able能;enable使能够;enabled是enable的过去式。根据上下文,这里讲的是以前人们对食人鱼的看法,应用过去时。食人鱼的群体活动可以赋予它们合作捕猎的能力。选项D
7.B答案解析:从“我们发现……”一句看出,与以前人们的看法不同,食人鱼的群体活动只是为了保护自己。应选择表示与前句意义相反的转折词。选项B
8.C答案解析:食人鱼会受到其他动物的攻击。这里列举几种动物,应用like,或such as。选项C是正确的。
9.D答案解析:食人鱼群体活动的目的是避免被杀戮(being killed)。Prevent sb.from doing sth.防止某人做某事,该词通常与from连用,排除选项A和B。of是介词,后跟名词性的词。所以,选项D是正确的。
10.B答案解析:由此往后连起来看,大意是食人鱼的群体组合是根据所面临的危险,根据水的深浅。并且,处于繁殖期的鱼处于鱼群的中央,以获得保护。of后应跟名词性词组,age前应有形容词修饰。Reproduce是动词,reproductive是形容词,reproduction是名词,reproductively是副词。选项B是正确的。Reproductive age繁殖期。
11.A答案解析:把处于繁殖期的鱼围在中间的目的是为了保护它们。For是介词,后用名词形式。选项A是正确的。For protection为了保护。
12.B答案解析:把处于繁殖期的鱼围在中间的目的是为了保护它们。For是介词,后用名词形式。选项A是正确的。For protection为了保护。
13.C解析:鱼群的大小组合肯定是根据可能面临危险的大小。Fate命运,destiny命运,risk危险,chance机会。选项C是正确的。
14.A答案解析:根据下一句:如果水位下降。说明这里应该是指水位比较高的时候。选项A是正确的。
15.B答案解析:For支持,against反对,without没有,towards朝、关于。根据原文,食人鱼组成大的鱼群作为保护以抵御捕食者。选项B是正确的。
答案解析:For支持,against反对,without没有,towards朝、关于。根据原文,食人鱼组成大的鱼群作为保护以抵御捕食者。选项B是正确的。
