一个小故事:
小明的妈妈看到小明总是忘记关灯,就对他说:“Yu shuld turn ff the lights when yu leave the rm.”(你离开房间时应该关灯。)小明不好意思地点头。后来他看到同学在河边乱扔垃圾,就对同学说:“Yu shuldn't thrw rubbish int the river.”(你不应该往河里扔垃圾。)同学听了觉得有道理,捡起了垃圾。小明用shuld和shuldn't帮助了别人,也改变了自己。
一、shuld / shuldn't 的基本用法
shuld 意为“应该”,用来提出建议、劝告,或表示责任、义务。
shuldn't = shuld nt,意为“不应该”,用来表示反对或劝告不要做某事。
Yu shuld drink mre water. (你应该多喝水。)
Yu shuldn't stay up t late. (你不应该熬夜太晚。)
句型结构:
• 肯定句:主语 + shuld + 动词原形 + 其他.
• 否定句:主语 + shuldn't + 动词原形 + 其他.
• 疑问句:Shuld + 主语 + 动词原形 + 其他?
Shuld I take an umbrella? (我应该带伞吗?)
Yes, yu shuld. / N, yu shuldn't.
二、shuld / shuldn't 的常见使用场景
1. 健康建议
Yu shuld eat mre vegetables. (你应该多吃蔬菜。)
Yu shuldn't eat t much junk fd. (你不应该吃太多垃圾食品。)
2. 环保建议(Unit 8 重点)
We shuld save water and turn ff the tap. (我们应该节约用水,关掉水龙头。)
We shuldn't waste electricity. (我们不应该浪费电。)
We shuld plant mre trees. (我们应该多植树。)
3. 学习建议
Yu shuld listen t the teacher carefully in class. (你应该在课堂上认真听讲。)
Yu shuldn't cpy thers' hmewrk. (你不应该抄别人的作业。)
4. 日常礼貌
Yu shuld say “thank yu” when smene helps yu. (别人帮你时应该说谢谢。)
Yu shuldn't talk ludly in the library. (你不应该在图书馆大声说话。)
三、shuld / shuldn't 与 must / have t 的区别
• shuld 表示“应该”,语气较弱,建议性,不做可能也没关系,只是不够好。
• must 表示“必须”,语气强烈,强制性,不做会有后果。
• have t 表示“不得不”,客观要求,外界压力。
Yu shuld see a dctr. (建议)
Yu must stp at the red light. (强制规则)
I have t finish my hmewrk tday. (客观要求)
shuld/shuldn't 记忆口诀:
shuld 应该做,shuldn't 不应该。
建议劝告语气柔,动词原形跟在后。
环保学习与健康,事事用它来开口。
