Sentence patterns
I think at the beginning we'd rather have some fairly quiet and peaceful music. 我想, 開始時, 我們寧可聽些柔和舒緩的音樂。
would rather寧愿, 表示選擇的意思。在使用這種表達方式時，要注意以下幾點:
would rather 后跟不帶to的不定式, 常用縮寫式 'd rather: I'd rather have something to eat. 我寧愿來點吃的。2) would rather的否定式是在would rather 后加not, 即 would rather not do sth.。例如: I would rather not go out tonight, if you don't mind. 如果你不介意的話，今晚我不想外出了。3) 在表示“寧愿......而不愿”時，要用would rather ...than ...這一結構，表示在兩者之中進行選擇。使用這一表達方式要注意“平行結構”，即在than 的前后要用兩個同類的詞或詞組，如兩個名詞，兩個動詞不定式，兩個介詞詞組等。如：I would rather listen to music than go swimming. 我寧愿聽音樂，而不愿去游泳。
