六、经典引文
七、词语用法
adv.(副词)- ago是表示时间的副词,其基本意思是“以前”,表示事情发生在“从此刻算起若干时间以前”,也可以表示“事情发生距现在有多长时间”。简言之, ago的时间参照点是现在。
- ago在句中一般不单独使用,须与表示时间的名词或副词搭配使用,且要放在它所修饰词的后面。
- ago短语在句中修饰谓语动词时,该动词一般须用过去时态。但在某些固定短语或人们意识到所涉及的事情是过去发生的时刻, ago也可用于一般现在时,着重表示“到现在已有多长时间了”。当不仅表示动作发生,而且强调动作的后果时, ago可和过去完成时连用。在强调句型中,如强调ago短语,谓语动词be可用于一般现在时,也可用于一般过去时。long ago用于加强语气时,也可与现在完成时连用。
- ago短语在句中修饰非谓语动词或者句中有情态动词时,除可与一般时连用外,也可和完成时连用。
- 在文学作品中为了叙述生动, ago可与现在完成时连用,也可用于一般现在时,这是因为作者与读者都沉浸在故事情节之中,而把作品中的人物与现实生活融合到一起了。
- ago短语通常在句中作状语,但有时它在句中也可作介词of的宾语、后置修饰语或表语。
- ago可用于疑问句。
- ago不用于比较等级。
- ago所适用的时态：通常来说，ago用于过去时态，不能用于完成时态，如不能说She has seen him a week ago，只能说She saw him a week ago。ago只有在有助动词或分词、动名词或不定式的形式中才能用完成时态。有时当语气强调“早已……”时，也可用完成时态。
She must have seen him a week ago.
She seems to have seen him a week ago.
I have long ago given up that habit.
- ago与before的比较：表示“早于现在多少时间前”，用ago。表示“早于过去某时多少时间前”，通常用before。不过英美人也有用ago，觉得语气比较生动。表示“早于将来某时多少时间前”，也用before。表示“早于任何某时（不是现在、过去或将来的某时）多少时间前”，仍用before。
He started five minutes ago.
He told me he had seen her a few minutes before.
When you call at the shop again this afternoon, you may be told that the book has been sold only a few minutes before.
He often forgets what he has heard only a few minutes before.
- ago后面带从句时，可以接that 引导的从句，而不可以用since。
He died 20years ago.(不带从句）
It was 20 years ago that he died.(带从句)
- 注意在as long ago as 18等表达方式中，第二个as后面没有in。通常说as long as forty years，不说as long ago as forty years；
- 句子She died three years ago next Monday指“她在3年前的下周一去世”，而句子It happened a fortnight ago tomorrow指“这事发生在13天以前”。“刚过去的第二个晚上”常用 two evenings ago来表示。
