英语表达中有时态之分，这与汉语完全不同。时态是表示谓语动作时间概念的动词形式，不同时间概念的谓语动作有不同的时态，每一个时态又有各自不同的动词形式，这是让学生常感困惑的地方，因此在进行时态教学时，，并准确理解其用法。 例如： 1．每个人都需要水和健康的饮食 Each person needs water and a diet of healthy food. 2．The moon travels round the earth once every month. 月亮绕地球每月转一次 3. When she was there, she often went to the supermarket. 她在那儿期间，经常去超市。 4.希望明天转晴。 We hope it will be fine tomorrow. ?Hopefully tomorrow will turn out fine. 5. 大火发生时500多人正在大楼工作。 Over 500 people were working in the building when the fire broke out on the 11th floor. 有学生这样翻译： Each person need water and a diet of healthy food. There are over 500 people were working in the building when the fire broke out on the 11th floor. There were over 500 people worked in the building when the fire broke out on the 11th floor. Over 500 people worked in the building when the fire broke out on the 11th floor. 通过此种练习发现学生学习起点不是很低， 对一般时态基本了解，但还存在几种障碍（动词错用；时态错误；句法混用等），也不能准确表达，结合此种情况进行指导，让他们教学小组讨论、合作探究解决问题，从而得出正确结论。 为了能够把学生所表现出来的问题和障碍及时有效的解决，下面以动词部分时态和语态教学设计几个步骤为例进行具体说明。 ?本节学习目标： 掌握一般现在时、一般过去时和一般将来时的结构和用法； 掌握现在进行时、过去进行时及过去将来时的结构和用法。 重点难点：一般过去时与过去进行时的异同；一般将来时与过去将来时的异同。 ?【小试身手】 （设计意图：通过此部分练习让学生对本节所掌握的时态有初步印象；同时让他们发现暴露出的问题并进行梳理。） 1. —Do you like the material? ?? —Yes, it______ very soft. ?A. is feeling????? ?B. felt????
