would rather、had rather...你都分得清嗎

Rather than

Rather than 意爲着代替或偏愛某物。

例句：

Rather than complicating matters further, we should just let Martha deal with it herself.

我們應該讓瑪莎自己處理這事，而不是使事情更復雜。

Would rather / had rather

它們的意義相同——即當你喜歡擁有或做一件事而不是另一件事。但是“had rather”更古老，不如“would rather”常用。一般來說，常用於縮寫形式（I'd rather），所以常常並不能確定是哪個詞組，但它們含義相同！

例句：

“Would you like to go to Sarah's house for dinner tonight?”

“你今晚想去莎拉家吃飯嗎？”

“I'd rather stay at home” (I would rather stay at home / I had rather stay at home)

“我寧願呆在家裏”（意義相同，但是形式不同）

Had better

Had better在給人建議或告訴別人該做什麼時使用。意爲現在或將來，而不是過去。一般使用had，而不是have。had better之後，使用不帶to不定式。Had better和“should”意思相同。

例句：

We had better leave early if we don't want to get stuck in traffic. (we should leave early if we don't want to get stuck in traffic – advice/suggestion)

如果不想堵車的話，我們最好早點走。（如果不想堵車的話，我們應該早點出發）。
