【分析】
这是一篇介绍饲养宠物鱼相关常识的完形填空题,解题时首先要通读全文,理清文章围绕鱼缸养鱼的各类注意事项展开的核心主旨,之后逐空结合上下文语境提示、词义辨析、固定搭配规则逐一筛选选项,遇到不确定的空可以先跳过,结合后文给出的线索反向推导,全部选完后代入全文通读验证逻辑是否通顺即可。
【解析】
1. 前文提到很多人把小鱼当宠物饲养,本句表达“他们把鱼养在装水的缸里”,keep有“饲养、存放”的含义,buy买、find找到、want想要均不符合语境,选A。
2. 本句表达“鱼缸是由透明玻璃制成的”,be made of是固定搭配,意为“由……制成(可直接看出原材料)”,其余选项语义均不符合,选B。
3. 后文提到人们可以看到鱼缸内部的鱼,说明是透过玻璃看,through表示从物体内部穿过,look through意为“透过……看”,look at看、look for寻找、look out of从……朝外看均不符合语义,选C。
4. 后文明确提到这些东西可以向水中释放氧气,后续也多次提到植物的作用,说明此处是往鱼缸里放对鱼有益的小植物,选B。
5. 本句表达“植物在其他方面也有作用”,other后接可数名词复数,other ways意为“其他方面”,another后需接单数名词,no不符合语义,else只能放在不定代词后,选A。
6. 此处表达鱼可以在植物间产卵,lay eggs是固定搭配,意为“产卵”,其余选项均不符合语义,选D。
7. 前文提到植物和鱼都需要光照,本句表达鱼缸可以放在窗户附近来获得光照,near意为“在……附近”,其余位置描述不符合逻辑,选C。
8. 后文提示“鱼缸里的水会变得太冷”,说明窗户会让冷空气进入,cold符合后文的冷的线索,选B。
9. 本句表示推测:水太冷的话鱼有可能会死,may表示“可能、也许”,用于不确定的推测,must必须、have to不得不、should应该均不符合推测的语气,选A。
10. 本句表达“热水也一样(也会杀死鱼)”,“so+助动词/情态动词+主语”是固定结构,意为“……也同样”,选A。
11. 根据常识鱼必须一直生活在水里,all the time意为“一直”,sometime某时、sometimes有时、some time一段时间均不符合语义,选C。
12. 后文提到鱼缸需要加盖子防止鱼跳出来,说明鱼可能跳出鱼缸,jump out of意为“从……跳出去”,选C。
13. 本句表达给鱼喂太多食物是不好的,food是不可数名词,too much用于修饰不可数名词,so many/too many修饰可数名词复数,much too意为“太”,选D。
14. 多余的食物沉到缸底会污染水质,让水变脏,dirty脏的符合逻辑,选A。
15. 前文提到要喂刚好足够的食物,标准就是鱼能在10分钟内吃完所有食物,finish意为“完成”,此处指吃完食物,选B。
