【正确答案】 B

【答案解析】[名师解析] 本文节选白一则动物故事，从前有一只猫，“从前”用英语说应该是 once upon a time，他住在一幢小屋里，那里还有很多小老鼠。这些老鼠不仅靠房主生活，而且他们还见什么吃什么。一开始主人还什么都不知道，但是当老鼠越来越多的时候，他就开始担心了。这句话有个时间上的变化，应该看出后面有个later，所以这里就是开始at first，first是形容词，表示“第一”，不能表示开始，根据文章意思，应该是越来越多，所以应该是more and more。于是有一天，这只猫接到了一个命令，他必须去抓老鼠，否则他就得滚蛋。根据题意，既然是命令，这里就应该是must。因为这个原因，猫开始一只接一只地抓老鼠，这里，“因为这个原因”应该是for this reason，如果要用because的话，那就应该用because of this reason，“一只接一只”固定的说法应该是one by one。这之后，老鼠中年长的领导召开了个会议，“召开会议”应该说hold a meeting，这里是过去时，应该用 held a meeting。每只老鼠都同意不要和猫战斗，相反地，他们应该采取和平的解决方法：搬家。这句话空格前面和后面是完全相反的意思，所以这个空格肯定是表示相反的词或词组，选项里的since是“自从”的意思，不符，instead是副词，后面不能直接接代词that，而instead of则是介词词组，后面可接跟that。然而这个会议被猫听到了，这里应该有个转折的意味，应该用but，于是猫也开始想该做什么了，这里有个宾语从句，由what引导。
