口诀巧记两种时态同学们在初一已经学过“一般现在时”（the Simple Present Tense）和“现在进行时”（the Present Continuous Tense）两种时态，你们掌握得怎么样？下面的两则口诀将帮你们巩固它们。
口诀一：一般现在时一般现在时态中，动词一般用原形。
表述事实讲真理，习惯动作常发生。
动词词尾加－s(es)，只表单数三人称。
若变一般疑问句，得看句型是哪种。
系表结构和there be, be 放句首可完成；若遇实义动词句，do或does莫忘用！口诀二：现在进行时 Look, Listen 是标志，现在进行正发生；有时now在句现，“be＋v－ing”时态成。
若问be用何形式，须看主语数、人称。
He ／ She is, I am． We, you, they后are紧跟。
v－ing形式更好记，三种构成要分清。
一般问句be提前，be后加not否定成！英语中考复习时态系列之（三）一般过去时一般过去时主要表示过去某时发生的动作或情况。
可以从以下几个方面来理解：1）过去某个时间所发生的动作或存在的状态。
e.g. I bought a new shirt yesterday. He was a worker two years ago.2）过去一段时间内，经常性或习惯性的动作。
e.g. When I was a child,I often played with fire.Li Lei always walked to school last term.3）谈到已故人的情况时多用过去时。
e.g. Lu Xun was a great writer.4）有些发生时间不是很清楚的情况，实际是过去发生的，也应用过去时态。
e.g. What did you say?另外，还可用过去时表示委婉的语气。
e.g. Could you lend me your pen?其结构是“主语+动词的过去式”。
be 动词的过去式为was, were；行为动词的过去式有规则变化和不规则变化两种，规则变化有以下几种情况：1）直接在动词原形末尾加-ed. e.g. work--worked; ask--asked;2）以e 结尾的动词只加-d. e.g. arrive--arrived; like--liked.3) 末尾只有一个辅音字母的重读闭音节，应先双写这个辅音字母，再加-ed. e.g. shop--shopped;4) 以“辅音字母+ y”结尾的动词，先把y 变成i，再加-ed. e.g. carry--carried; study--studied.有些动词变过去式是不规则的,e.g. fly--flew; break--broke; teach--taught.这些需要象生单词一样记住。
其句式变化分为两种情况1) 含有be 动词的依然在be 上做文章。
e.g. I was born in 1980. I was not born in 1980. Were you born in 1980?2) 含有行为动词的变否定句要在行为动词前加助动词didn't，同时把动词变成原形；变一般疑问句,在句首加助动词did，同时把动词变成原形。
e.g. I bought a gift for my mum yesterday.I didn't buy a gift for my mum yesterday.Did you buy a gift for your mum yesterday?其时间状语为yesterday 或由其构成的短语，e.g. yesterday morning；由“last + 时间”构成的短语，e.g. last year;由“时间段+ ago”构成的短语, e.g. three days ago;另外,还有on the morning of Monday, just now 等，以及一些表示过去时态的从句。
注意，在宾语从句中主句为过去，一般从句也为过去。
常见错误如下:一、把动词变成过去式易出错例: 1. They stoped (stop) talking just now.2. They plaied (play) football yesterday.答案: 1. stopped 2. played解析: 我们可以记住下面的口诀:“动词变成过去式,双写规律要牢记；y 前若是辅音字，y 变i 加-ed; y 前若是元音字，只须直接加-ed.”二、忘记把动词变成过去式例: I fly (fly) kites on the afternoon of Sunday.答案: flew解析: 我们可以记住下面的口诀:“一般过去时态里，过去形式莫忘记”。
三、在句式变换时易出错例: 1. We didn't went (not go) out last Friday.2. Did you had (have) a good time yesterday?答案: 1. didn't go 2. Did have解析: 请记住口诀“见助动, 用原形。
”四、易与单三人称作主语的一般现在时弄混例: He taughts (teach) me English last year.答案: taught解析: 行为动词的过去式无人称和数的变化。
即使主语是单三人称，也和其它人称所用动词的形式一样。
五、易与现在完成时弄混例: 我看过这部电影I saw(see) the film.答案: I have seen (see) the film.解析:“我看过这部电影”说明我了解这部电影的内容，强调现在的情况，应用现在完成时；一般过去时态的句子只是说明我看了这场电影，与现在无关。
六、易与过去进行时弄混，这里不在重复。
