過去常常……(現(xiàn)在已不這樣)(expressing a frequent or continuous action in the past)：They～play football， didn't they?他們過去常踢足球，對(duì)嗎?U～you to know him? 你過去對(duì)他了解嗎?Didn't there use(d) to be a church at the corner of the street?在大街拐角處不是曾有一座教堂嗎?It～to be said that... 過去常說…… I don't go to see the film so often as I～(to). 我不像過去那樣常看電影了。

【說明】used to 的否定式是used not to，did not use to， use(d)n't to;不用did引起的否定式、疑問式比較陳舊而且正式，如：I usedn't to like her. Used you to work there? There used to be a theatre， use(d)n't there?

【用法】used to和would都可用來表示過去的習(xí)慣和狀況。used to 有“但現(xiàn)在已不……”之意，可用于故事敘述的開始，而would則不能用于敘述的開始，如：We used to swim every day when we were children. We would run down to the river and jump in... (我們小時(shí)候每天下午都游泳。我們往往跑到下面河邊縱身一跳……)此外，would另含“意愿”在內(nèi)，因此表示過去的習(xí)慣和狀況時(shí)，往往有“主觀的意愿”，如：He used to catch cold in early winter. (他過去初冬時(shí)節(jié)常感冒。)這里如果用would就不妥了。
