An elementary school teacher asked a student why he was late.

He replied, "A nearby sign said 'School ahead, slow down，go slow,' so that's what I did."

Notes:

1. An elementary school teacher asked a student why he was late.

一个小学老师问一个学生为什么迟到。

表示“做什么事迟到”，可以直接在late的后面加动名词，如：I was very late getting home yesterday.我咋天很晚回家。也可以加上for，再加名词，如He was late for meeting. 他开会迟到了。

elementary [ˌelɪˈmentri] adj.初等的 elementary school 小学

2. He replied, "A nearby sign said 'School ahead, slow down，go slow,' so that's what I did."

他回答说：“附近有一个标志写着：‘前有学校，减速，慢行。’所以我就照做了。”

句中第一个slow是动同，表示“减速”，他后面的down是副阂，表示“减弱”;第二个slow是副词，表示“缓慢地”, slow放在动作动词后面当副同，是口语用法。

在美国.当你看到黄色菱形标志上面写着SCHOOL CROSSING,或是黄色长方形标志.上面有一个奔跑的孩子，上方写着SLOW.表示你将进人学校区。在美国的学校区内违规，驾驶执照可能会被吊销。

sign [saɪn] n.标志
