在形式众多的英语练习中,有关时态的练习一直是令广大学生深感头疼的一种。为什么时态会成为英语学习中的难点呢?最主要的原因即在于汉语中不存在时态形式。汉语中时态的表达是通过动词词形的变化,而是用特定的词汇来体现的。如表示时间的“现在”、“将来”、“过去”等和表示方式的“正在”、“将要”、“已经”等。而英语的时态则是通过动词词形的变 In many forms of English practice, the practice of the tense has always been a kind of headache for the majority of students. Why do tenses become difficult in English learning? The main reason is that there is no tense form in Chinese. The expression of tenses in Chinese is reflected by the change of verb morphology, but embodied in a specific vocabulary. For example, “current”, “future”, “past”, etc. indicating the time, “current”, “to be”, “already”, etc. of the expression. The tense of English is the change of verb form.
