haveto和should的用法区别
"Have to" 和 "should" 都是表示义务、责任和建议的情态动词。然而,它们在用法上略有不同:
11."Have to" 表示必须做某事,通常是由外部因素强制性地施加给某人的义务,比如规定、法律、约束等。例如:
I have to go to work every day.
Students have to wear uniforms at school.
You have to pay your taxes by April 15th.
2."Should" 表示应该做某事,是一种建议或期望,但并没有强制性的义务。例如:

I should call my mother more often.
She should study harder if she wants to pass the exam.
总之,"have to" 是强制性的义务或责任,而"should" 是非强制性的建议或期望。
"Have to"和"should"都是表示义务或推荐的动词,但它们之间的用法和含义有所不同。
"Have to"表示必须、必需或强制性的要求。这个词通常用于描述一项任务、工作、义务或规定是必须履行的,其否定形式为“do not have to”。例如:
I have to finish my homework before I can watch TV.(我必须在看电视之前完成我的家庭作业。)
We have to wear masks in the hospital.(我们在医院必须戴口罩。)
"Should"表示一个建议、意见或期望。这个词强调的是根据某些标准或习惯,某种做法或行为应该或理应被采取或实施。其否定形式为“should not”或“shouldn't”。例如:
You should drink more water if you want to stay healthy.(如果你想保持健康,你应该多喝水。)
We shouldn't leave food uncovered, as it attracts flies.(我们不应该让食物暴露在外面,因为会吸引苍蝇。)
综上所述,"have to"是指必须履行的任务、工作或规定,而"should"则是指建议、意见或期望。
