必考短语

(1)since then此后；自此；从那时以来

用法讲解

表示“（时间）持续”时，since和for都可与表示时间的词连用。 (1) for后跟一段时间，表示某事进行了多长时间， 例：She slept for eight hours. 她睡了8个小时。 (2) since后多接某一时间点，表示某事开始的时间。 例：She has been with the group since it began. 这个集团创建之初她就在那里工作。

表示“因为”时： since：当所述原因是已知的客观事实或被当作推断的理由时用since，语气略强于 as。 because：语气最强，表因果关系，通常用来回答由why引导的疑问句。由because引导的分句置于句首时，须用逗号与主句隔开，置于句末时则不用隔开。如所述理由是明显或已知的，则用as较because更为合适。 for：属于并列连词，由它引导的分句表示补充说明性的理由，通常只能置于句末，且必须用逗号与前面的分句隔开。
