一、重点难点讲解 1.动词的时态 在英语中,不同时间发生的动作或存在的状态,要用不同的动词形式来表示。 例如:他母亲1980年在工厂工作。 His mother worked in a factory in 1980. 这句话中,动词“工作”的形式要用“worked”; 而如:他母亲现在正在工厂工作。 His mother is working in a factory. 这句话中,动词“工作”的形式则要用“isworking”. First, focus on difficulties to explain 1. Tenses of verbs In English, the different actions or states of existence occur at different times, use different verb forms to express. For example: His mother worked in a factory in 1980. His mother worked in a factory in 1980. In this sentence, the form of the verb “work” was “worked”; for example, his mother was working in a factory. His mother is working in a factory. In this sentence, the form of the verb “work” is “isworking”.
