为什么是had better不是have better或has better?

Question

如题所述

Answer 1

had better有“最好”的意思，常用语建议或请求时，表达比较委婉，它暗示对方有义务去做某事，因此通常用于长辈对晚辈或上级对下级等，而不宜反过来用。had better可将其视为“情态”动词，可用于一切人称，没有任何词形变化。have better和has better表示有比较之下“有更好的”的意思，一般局限于主语单复数，has better用于第三人称单数时。
had better，读音：英 [hæd ˈbetə] 美 [hæd ˈbɛtɚ] ，意思：应该，最好还是。
(1) had better 用于提出建议或请求时，并不是一个很客气委婉的表达，它暗示对方有义务去做某事，因此通常用于长辈对晚辈或上级对下级等，而不宜反过来用。
(2) had best与had better用法和含义均差不多，但不如had better普通：
You had best get home before midnight.你最好在午夜之前回到家里。
We had best be going.我们最好现在就走。
(3) 有时可省略其中的had：
You better stop arguing.你们最好不要争论了。
Better not wait for him. 最好不要等他了。
Better say yes, if they ask you. 如果他们问你，你最好说“是”。
(4) 有时为了强调，可将better置于had之前：
"I promise I’ll pay you back." "You better had." “我保证还给你。”“你最好还给我。”
