刚刚longman了一下,signal按LZ说的做verb的话, to make a sound or action in order to give information or tell someone to do something: signal at Mary signalled wildly at them, but they didn't notice. signal to The judge signaled to a police officer and the man was led away. signal for He pushed his plate away and signalled for coffee. signal (to) somebody to do something She signalled to the children to come inside. signal that The bell signaled that school was over. 不知道LZ说的是哪个~~哈哈,恭喜LZ啦!
