考点速记
考点 01 should 的用法
We should warm up first. 我们应该先热身。
We should also keep to the right. 我们还应该靠右走。
解析:
should 是情态动词,表示「应该,应当」,用来给出建议或说明应该做的事情。
一、should 的基本结构
主语 + should + 动词原形 + 其他。
例句:We should warm up first. 我们应该先热身。
We should keep to the right. 我们应该靠右走。
He should listen to the teacher. 他应该听老师的话。
二、should 的特点
1.should 是情态动词,没有人称和数的变化。无论主语是 I, we, you, they, he, she 还是 it,都用 should,动词一律用原形。
2.should 后面接动词原形,不能接 to do 或 doing。
3.should 的缩写形式为 'd(如 I'd = I should),但在小学阶段一般写全称。
三、should 的常用场景
1.给出建议:You should drink more water. 你应该多喝水。
2.说明应该做的事情:We should keep our classroom clean. 我们应该保持教室干净。
⚠ 易错提醒:should 后面必须接动词原形,不能接 to do 或 doing,如 should to go(×)→should go(✓)。无论主语是第几人称,should 都不变化,如 He should goes(×)→He should go(✓)。

You shouldn't run on the stairs. 你不应该在楼梯上跑。

You shouldn't sit down right now. 你不应该马上坐下。
解析:
shouldn't = should not,是 should 的否定形式,表示「不应该」,用来给出不要做某事的建议。

例句:You shouldn't run on the stairs. 你不应该在楼梯上跑。
We shouldn't jump from the stairs. 我们不应该从楼梯上跳下。
You shouldn't pull his clothes. 你不应该拉他的衣服。
二、shouldn't 的特点
1.shouldn't 是 should not 的缩写,两者意思完全相同。
2.shouldn't 后面同样接动词原形,不受主语人称影响。
3.should 和 shouldn't 后都不加 to。
三、shouldn't 的常用场景
1.给出警告或禁止:You shouldn't run on the stairs. 你不应该在楼梯上跑。

⚠ 易错提醒:shouldn't 后面接动词原形,不能接 to do 或 doing,如 shouldn't to push(×)→shouldn't push(✓)。shouldn't = should not,不能写成 shouldnot 或 should'nt。
