英語四級閱讀關(guān)鍵句：252. A graduated license requires th

252. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving with night or passenger restrictions, before graduating to full driving privileges.

譯文

畢業(yè)證需要青少年首先證明自己可以在一位成年人在場的情況下駕駛，并在完全獲得駕駛特權(quán)之前，經(jīng)歷一段時間的夜間或乘客限制駕駛。

點睛

本句的主干是license requires that。that引導(dǎo)的是requires的賓語從句，in the presence of an adult為狀語，followed by a period of driving with night or passenger restrictions和before graduating to full driving privileges皆為時間狀語。

capable of doing sth.的意思是“有能力做某事”，也可直接用做capable of sth.。如：

She is capable of better work than this. 她有能力把工作做得更好。

in the presence of sb.的意思是“在……面前，有……在場”，也可用作in sb.'s presence。如：

You never seem at ease in my presence. 你在我面前總是顯得不自在。

graduate to的意思是“逐步發(fā)展到，升級到”。如：

She finally graduated to having a role in a movie. 她終于能在電影里扮演角色了。
