Key:D devote oneself to(=be devoted to)献身于,;stick to坚持;referto提及;参考;它们都不合句意。lead to中的to为介词,该句为强调句型,即Sleeping late in the morning leads to being late for work的强调形式。

从属连词before最基本的意思是“在……之前”。但在具体的句子中,译法多种多样,可译为“……才……”;“……就……”;“还没有……就……”;“没等……就……”。before引导的状语从句中不能使用表示将来的will。
四、词馁辨析
17.common/usual/ordinary/normal
这四个词(特别是前三个)有时有通用的情况,但各自还是有各自的侧重点:
common意为“普遍的、常见的、共有的”,具有时常发生、出现频率高、范围广的含义; ’
usual意为“通常的、一贯的、平常的”,指在某一地方、某一时间或某人身上平时常见的;
ordinary意为“普遍的,平凡的”,主要指人平凡或事物合乎常规,并不特殊,没有什么突出特点;
normal意为“正常的,常规的”,指在正常范围之内。
解题警示
common强调“普遍性”和“范围”,usual强调“常规性”,表达“时间”方面的概念。
18.no longer/not...any longer/no more/not…any more
no longer=not…any longer不再(现在与以前不同)
no more=not…any more二者都有“不再”的含义
解题警示:
在表示“(时间上、动作或状态持续上)不再”时,常用no longer,较少使用no more
在表示“(数量上、动作反复上)不再”时,常用no more.
五、语法要点
19.直接引语和间接引语(复习)(略)(见第1讲和第2讲)
六、交际用语
20.原因和结果(Causes and effects):
Why…? Because/As/Since….

As a result of.… It follows that….
It will use…. It will lead to…. ’
