Today a set of car keys caught WALL · E’s attention. Not knowing what they were, he went about inspecting them. He pushed the remote lock button, and somewhere deep in the trash heap a car alarm chirped. That was interesting.
今天一串汽车钥匙吸引了瓦力的注意力。他不知道它们是什么，就仔细地查看了它们。他按了一下遥控钥匙上的锁车键，垃圾堆深处就传来了汽车防盗报警器发出的“啾啾”声。这真有趣。
a set of keys意为”一串钥匙“，
作主语时谓语动词用单数形式is。a set of keys后加is,不能用are。
例如：A set of keys is on the desk。桌子上有一串钥匙。
catch one’s attention吸引某人的注意。catch的过去式为caught。
