问题 Notice how you can change MICE into CATS in four moves, changing only one letter at a time and always making a complete word:
MICE
MACE
MATE
MATS
CATS
This is called a ladder graph.
Now turn DUST into TANK in four steps, changing one letter at a time. These clues may help you:
DUST
______ (Evening)
______ (An elephant has two)
______ (A job of work)
TANK
选项
答案 DUSK TUSK TASK
解析 题干要求找到将MICE通过四个步骤转化为CATS的规律(每次只改变个字母)，再按照同样的规律，将DUST变成TANK，补充中间的三个单词。通过观察发现，DUST需要改变个字母，改变后的字母具有evening(夜晚)的含义，因此，这个词为DUSK；再改变一个字母，变后的单词意思是an elephant has two(象牙)，因此，这个词为TUSK，再改变一个字母，使单词意思变为a job of work(任务)，因此这个词为TASK。所以答案为dusk(黄昏)，tusk(象牙)和task(任务)。
