一 一般现在时 一般现在时是表示现在经常反复的动作 存在的状态或习惯性的动作的时态 常与状语 always usually often sometimes seldom never 连用 学习一般现在时 有以下四大难点 难点一 不清楚什么是三单 一般现在时的主语是第三人称单数时我是这样来帮他们区分什么是三单什么是非三单 顺口溜 除去 I 和 you 外 单人单物是三单 3 难点二 不清楚三单动词的变化规律 关于一般现在时第三人称单数动词的变化规律 总结如下 变化规律 动词三单现在式 一般词尾加 s s x ch sh o 在词尾 直接加上 es 辅音字母 y 来结尾 变 y 为 i 是正规 es 后边紧跟随 study studies 看明白 元音字母 y 来结尾 直接加 s play plays 看明白 难点三 一般现在时疑问句和否定句的变法不清晰 孩子难于掌握 可归纳成三步法 顺口溜 一找 二添 三注意 变疑问句 一找 一找 即找到 be 动词 am is are 把它放句首 二添 即在找不到 be 动词时 需要在句子首位添助动词 do 或 does 三注意 即注意一二人称互变 注意 some 时要变为 any 如果主语是三单就添 does 注意在添 了 助动词后 句子中的实义动词要恢复原形 变否定句 一找 即找 be 动词 am is are 找到其中一个后在 be 动词后加 not 二添 即是在找不到 be 动词时 在主谓之间添 don t 或 doesn t 三注意 是在添了 don t 或 doesn t 之后 实义动词要恢复原形 难点四 一般现在时的基本用法不熟悉 很多学生虽然对一般现在时有了一定的认识 但对于它的几种用法始终是盲目的 对于这几种基本的 用法很多学生在心中没有一个完整的概念 但可用歌诀这样描述 关于一般现在时 学生还要记住一句非常重要的话 即 时时心中有数 学英语必须时时刻刻 注意单复数和时态的变化 如果每一个学生能够巧妙记住以上几点 攻克四大难关 现在的难关 也将变成 过去式 1 My mother work in a primary school and I study in the same school 2 I have a bike and Ben have a bike too 3 My sister be a pupil She study very hard 4 Who cook breakfast for your family 5 My father is a teacher He teach Chinese in a primary school 二 一般过去时 要点一 概念要清晰 4 一般过去时表示过去某个时间发生的动作或存在的状态 常和表示过去的时间状语连用 如 last year yesterday last week in 1980 two days ago a moment ago 等连用 也可表示过去经常 反复发生的动作 常和 often always 等频率副词连用 例如 I saw him in the street yesterday 昨天我在街上看见他了 Li Mei always went to school on foot last year 去年李梅总是步行上学 要点二 4 大句型要掌握 1 Be 动词在一般过去时中的变化 am 和 is 在一般过去时中变为 was was not wasn t are 在一般过去时中变为 were were not weren t 带有 was 或 were 的句子 其否定 疑问的变化和 is am are 一样 即否定句在 was 或 were 后加 not 一般疑问句把 was 或 were 调到句首 2 行为动词在一般过去时中的变化 肯定句结构为 主语 动词的过去式 其它 否定句结构为 主语 did not didn t 动词原形 其它 一般过去时的一般疑问句的构成 Did 主语 动词原形 其它 特殊疑问句的构成 疑问词 did 主语 动词原形 其它 要点三 4 大用法请牢记 A 带有确定的时间状语 B 表示过去连续发生的动作 C 表示过去一段时间内经常或反复的动作 D 强调已经终止的习惯要用 used to 要点四 动词的过去式的变法和发音是难点 一般过去时中最难掌握的就是 动词过去式 了 大部分学生对过去时的用法和概念都可以达到清 晰的认识 但是在动词的变形上却难以把握 动词过去式的变法总结如下 一 规则动词的 4 大变法 1 一般情况加 ed look looked 2 以不发音 e 结尾直接加 d live lived 3 以 辅音字母 y 结尾的动词 改 y 为 i 加 ed study studied 4 以重读闭音节 即辅音 元音 辅音 或 r 音节结尾 末尾只有一个辅音字母的动词 要先双写这 个辅音字母加 ed stop stopped 动词的变形除了掌握它的一般规则外更重要的是需要同学们在平时的学习中多积累 多记忆那些不 规则动词 这样一般过去时的学习才会达到更好的效果 二 动词过去式的发音 1 ed 加在清辅音后面读 t looked 2 ed 加在浊辅音或元音结尾的 读 d lived d 3 ed 加在 t 或 d 后面 读 id wanted tid visited tid 5 要点五 顺口溜大盘点 顺口溜 一般过去时并不难 表示过去动作 状态就要谈 动词要用过去式 时间状语句末站 否定句很简单 didn t 站在动词原形前 其它部分不要变 一般疑问句也好变 did 放在句子首 主语 动词原形 其它部分依次走 特殊疑问句也简单 疑问词加一般疑问句就不烦 最后一条请注意 动词过去式要牢记 即时演练 1 My father not stay at home yesterday He go to Guangzhou 2 they visit the zoo last Sunday 3 Who teach you maths last year Mr Liu do 4 When you take these photos I
