初中英语语法——动词的时态
动词的时态 一、考点解读 今天我们复习动词的时态，英语的时态是同学们学习英语的难点，在各地的中考题目中许多题型都会有对于动词时态的考查。出现较多的是在单选，完形填空，及其在第二卷中出现的根据汉语意思填词的题目，还包括翻译句子，书面表达。可以说中考题目中大部分都会涉及到动词的时态。既是难点也是重点。在今天的专题中我们复习初中阶段需要掌握的八个时态。 1．一般现在时 2．现在进行时 3．一般过去时 4．过去进行时 5．一般将来时 6．过去将来时 7．现在完成时 8．过去完成时 二、专题梳理 初中阶段所学的英语的时态有8种。英语的时态有很强的表达能力，能使句子的意思明确，能显示细微的差异，能使句子生动逼真。但它们不是相当灵活，在不同的时间中，要用不同的形式，这是与中文大不相同的地方。 1．一般现在时：一般现在时是描述经常性、反复性的动作、性质或状态的时态。 （1）一般现在时的时间状语通常有： ①often ②usually ③always
④seldom ⑤sometimes ⑥every＋时间 ⑦次数＋时间 ⑧on＋时间 ⑨in＋时间 ⑩没有时间，但表示客观存在的事实 （2）一般现在时动词的形式主要用动词原形表示，但如果主语是单数第三人称时，则在动词后加s或es，变成否定句和疑问句时，又将s、es去掉，还为原形。 ①be动词的一般现在时的构成 否定式和疑问否定式如下表所示： ②其他实义动词的一般现在时的构成
其他实义动词一般现在时的构成如下 表所示（以动词work为例） 特别提示： have(has)在表示“有”时，否定形式为haven’t(hasn’t)或have not(has not)，变为疑问句时可直接把have(has)放在句首也可借助于助动词do(does)。当不表示“有”的意思时，其否定句和疑问句只能加助动词do(does)构成。 e.g.Has she any experience in teaching piano lessons？(√) Does she have any experience in teaching piano lessons？(√) 她有教钢琴的经验吗？ Had you a good time going hiking yesterday？(×) Did you have a good time going hiking yesterday？(√) 你昨天徒步旅行玩得开心吗？
