不是.
had better （常简写为 'd better ）意思是“最好……”,用于表示对别人的劝告、建议,或表示一种愿望.其用法有以下几点：
一、 had better 后面必须跟动词原形,构成 had better do sth.句型.这里的 had 不能用 have 来替换.例如：
Tom,you'd better go there today.
汤姆,你最好今天去那儿.
二、不论主语是第几人称,不论句子是什么时态,都要用 had better 的形式.例如：
Now you （ he / we ） had better listen to the teacher.
你（他 / 我们）现在最好听老师讲.
三、 had better 可用的时态有现在时、将来时和进行式（表示讲话人提出建议时,动作正在进行）三种.had better + have + v.-ed 表示“本该做却没有做的事”.例如：
Now you had better listen to the radio.
你现在最好听收音机.
You had better start tomorrow.
你最好明天动身.
We had better be watching the TV play.
我们最好现在正在看电视剧.
You had better have done it.
如果你把那件事办妥就好了.（但实际上你没有那样做）
四、 had better 常用的否定形式是将否定副词 not 直接放在 had better 的后面.例如：
You had better not miss the last bus.
你最好不要错过末班车.
注意：否定副词 not 绝不能放在 had 的后面.例如不能说：You hadn't better go.而应该说：You had better not go.
五、 had better 的疑问式.had better 通常不以普通疑问句的形式出现.但有时用于否定疑问句,常用 Hadn't ＋主语＋ better 结构,作为一种劝告形式时,要比肯定形式的语气更婉转一些.例如：
Hadn't you better take an umbrella?
你不认为该带一把伞吗?
六、 had better 在反意疑问句中,疑问部分一般用“… had ＋主语?”,但有时可用“… will you?”表示一种请求或建议.例如：
You'd better not go out today,had you?
今天你最好不要外出,好吗?
I must stay at home this afternoon.You had better come to my house,will you?
今天下午我必须留在家里.你最好来我家,好吗?
七、在祈使句中,had 有时可以省略.例如：
Better not do it.
最好别做那种事.
Better not wait for them.
最好不要等他们.
八、 had better 的被动式.例如：
You had better have done it.→ It had better have been done.
九、 had better 在间接引语中的用法.在直接引语变为间接引语的过程中,had better 同第一人称或第三人称连用时,保持不变； had better 同第二人称连用时,可以保持不变,也可用 advise ＋宾语＋不定式（宾补）来表示.例如：
He said,“ Ann had better hurry.”→ He said （ that ） Ann had better hurry.
He said,“ I had better hurry.”→ He said （ that ） he had better hurry.
十、 had better 在表示对别人的劝告、建议时,不宜用于与陌生人、长辈及上级的交谈中.对长辈说话时,最好不用 had better .比较有礼貌的说法是：It might be better for you … ; It would be better for you ….例如：
It might be better for you to help me,Grandpa.
爷爷,您最好能帮我一下.
