Don’t use water to put out the fire if oil catches fire. As is known, oil ____ float on water. |
答案
D |
解析
试题分析:考查情态动词用法。本题中的will表示倾向性,如The door will not open。门无法打开。句意:如果油着火了,请不要用水来灭火,众所周知,油是会漂浮在水的上面的。故D正确。 点评:在平时的学习中既要注意情态动词的基本含义,也要注意情态动词的特殊意义,如will表示倾向性;should竟然;mustn’t禁止,千万不能;等等。情态动词Shall用于所有人称,表示命令,警告,允诺;以及法律规定中要做的事情。 |
