35.英语时态无处不在
时间是大家共有的,时态是英语特有的。什么时间做什么事,中文里只需要使用一些辅助词,如经常,正在,即将,已经等就可以表达清楚了,而英语却要使用动词不同的时态或句式。这些时态和句式常常难住了不少人。所谓时态,就是关注什么时间做什么事。这个问题弄清楚了,许多事情就好办了。
英语时态,无处不在。出口提笔,不离不弃。英语里共有十六种时态。最常见的,也是高考常考的以前只有八种,现在已扩充到十二种。每年高考英语试卷十五个单选题就有两三分考时态,完形填空里也偶尔出现,25分书面表达法几乎是句句离不开时态。由此可见,时态学好了,优势就是你的了。
学习英语时态,首先要记住不同时态的构成,它们相当于数学公式。以write为例,列出英语里常见的十二种时态,供参考。一般现在时(write\/writes);一般过去时(wrote);一般将来时(will\/shall write);过去将来是(would\/should write);现在完成时(have\/has written);过去完成时(had written);现在进行时(is\/am\/are writing);过去进行时(was\/were writing);现在完成进行时(have\/has been writing);过去完成进行时(had been writing);将来完成时(will\/shall have written);将来进行时(will\/shall be writing)。
