Let's play a game.
现在进行时:主语 + am/is/are + 动词 - ing + 其他. (现在进行时)
原文句:The monkeys are riding bikes very fast in the street.
解析:现在进行时,表此时此刻正在做的动作;monkeys 是复数,所以用 are+riding;
动词 - ing 变化:ride→riding(去 e 加 ing)。
结构:单数主语→is+doing;复数主语 / I→am/are+doing
例句:The boy is running in the street. 那个男孩正在街上跑。
Language points
一般现在时:Sometimes, 主语 + 动词原形 / 三单 + 其他.
原文句:Sometimes, he puts his hands behind his head.
解析:sometimes 是频度副词,表 “有时候”,可放 ** 句首(加逗号)** 或句中;主语 he 是第三人称单数,动词用三单形式(put→puts)。
例句:Sometimes, I walk to school. 有时候,我走路去上学。
Language points
一般现在时的否定句:
主语 + don't/doesn't + 动词原形 + 其他. (一般现在时否定句)
原文句:He doesn't stop at the red light.
解析:一般现在时否定,表 “习惯性 / 经常性不做某事”;主语是三单(he/she/it)用doesn't + 原形,非三单用don't + 原形;注意:助动词后动词必须用原形(stop)。
例句:We don't play in the street. 我们不在街上玩耍。
Language points
句型:Are you all right → 应答:I’m OK./Yes, I'm fine.
原文句:Are you all right I’m OK.
解析:日常交际语,用于他人发生意外 / 摔倒后,询问身体状况,答语固定,简单易记。
拓展:若受伤可答:No, I'm not OK. 我不舒服。
Language points
表建议/劝告:You should + 动词原形 + 其他. (表建议 / 劝告)
原文句:You should stop at the red light!
解析:情态动词 should 表 “应该”,用于对他人提交通规则 / 安全方面的劝告,语气委婉;后必须接动词原形,否定式:shouldn't(should not)+ 原形。
例句:You should walk on the sidewalk. 你应该在人行道上走。
Language points
It's + 形容词 + to do sth. (形式主语句型)
原文句:It's dangerous to ride so fast.
解析:小学核心重点句型,It 是形式主语,真正的主语是后面的to do 不定式,用于表达 “做某事是…… 的”;dangerous 是形容词,表 “危险的”。
替换形容词:It's safe to stop at the red light. 红灯停是安全的。
It's important to obey traffic rules. 遵守交通规则很重要。
Language points
I won't do that again. (表 “不再做某事”)
原文句:I see. I won't do that again.
解析:won't=will not,是 will 的否定式,后接动词原形,用于犯错后承诺 “将来不再做某事”,贴合交通规则认错场景。
例句:I won't run in the street again.
我不会再在街上跑了。
Language points
语法点 1:现在进行时(表 “正在做”)
核心结构:am/is/are + 动词的 - ing 形式
原文例子:The monkeys are riding bikes.(复数主语 + are+doing)
动词 - ing 变化规则(小学基础):
直接加 ing:look→looking
去 e 加 ing:ride→riding /stop→stopping
双写末尾字母加 ing:run→running /fall→falling(本单元暂记即可)
关键:看到 “正在、此刻” 等词,或动作正在发生,用现在进行时。
Language points
语法点 2:一般现在时的否定句+动词三单
(1)动词三单(主语为 he/she/it/ 单数名词)
原文例子:he puts / he looks / he runs / he falls
简单规则:一般动词直接加 s(put→puts);
以 s/x/sh/ch/o 结尾加 es(go→goes);
辅音 + y 结尾变 y 为 i 加 es(fly→flies)。
Language points
三单(he/she/it) doesn't + 动词原形 He doesn't stop at the red light.
非三单(I/we/you/they) don't + 动词原形 We don't ride fast in the street.
易错点:助动词 doesn't/don't 后,动词必须变回原形,不能用三单!
Language points
频度副词sometimes的用法
含义:有时候(频率较低)
位置:① 句首,后加逗号:Sometimes, he looks at people around him.
② 句中(be 动词后 / 实义动词前):He sometimes rides fast.
同类词:often(经常)/usually(通常),用法和 sometimes 一致。
Language points
