a long line of people waiting to get in..如何分析waiting
自己会做.但是教别人就不知道怎么说了,这里wait 有其他时态的形式,waited wait being wait如何说明要用waiting

弄清现在分词与过去分词的关系就明了了!V-ING现在分词修饰PEOPLE表示“正在进行的动作”“正在等待,”动词加ED过去分词表示“被动,已经完成的动作”,因为“等待”这个词比较特殊一般不用被动式,用不定时代替这个’被‘的动作,如THEY WERE ASKED TO WAIT.如果有人问这个waited是指过去式啊过去在那排队等一定要是被动吗请区别下面两个句子:1,People waiting to get in became noisy. 等待插队的人们嘈杂起来。这里WAITING是现在分词.整个句子是一般过去时态,见BECAME. 2, People waited to get in. 人们等着插队。这里WAITED 是过去式。
