Grammar Focus 一、比较过去进行时与一般过去时 1. 强调动作的角度不同 一般过去时强调动作的发生或状态的存在。其时间状语主要有：yesterday (morning, afternoon, evening), last night (week, month, year), ago, the day before yesterday, in 2003, just now, long long ago, one day等；而过去进行时强调动作正在进行，其时间状语主要有：at this/that time yesterday, the whole evening, all day yesterday等。 如： 1) I got up at five the day before yesterday. 2) He was painting the lab the whole day yesterday. 2. 情感不同 一般过去时是对过去事实的客观描述，语气比较客观、肯定；过去进行时有时也可以表示埋怨、厌烦等情绪，带有描绘性和感情色彩。如： The plane took off late this morning. 这架飞机今天早上起飞晚了。 (说明客观事实) The plane was always taking off late. 这架飞机总是起飞晚。 (带有埋怨情绪，指责某事的发生) 二、比较现在完成时和现在完成进行时 1. 现在完成时以现在的时间为基点，强 调到目前为止动作的完成和结果，与现在的情况有联系，对现在也有影响。而现在完成进行时强调动作的延续性，可能还将继续下去。如： I have painted the house green. The house was white, but now it’s green. My hands are very dirty. I’ve been painting the house. 2. 现在完成进行时往往表示动作在重复，现在完成时则常常不带重复性。如： Have you been meeting her lately? 最近你经常见她吗？ Have you met her lately? 最近你见过她吗？ 3. 现在完成进行时比较生动，有时含有 明显的感情色彩，而现在完成时往往 只说明一个事实、一种影响或结果，平 铺直叙，没有什么感情色彩可言。 如： Have you been waiting long?(较生动) Have you waited long?(较口语化) I have been waiting to meet you for long.(更礼貌) I have long waited to meet you.
