應(yīng)該是often和usually的區(qū)別.
這兩個(gè)詞均為時(shí)間頻度副詞,但表示的時(shí)間程度不同.其區(qū)別是：
1) usually(75%)意為“通?！?著重表示已形成習(xí)慣的動(dòng)作,反義詞為unusually.如：
They usually do some shopping on Sunday.他們通常星期天買東西.
What time do you usually have lunch?你通常什么時(shí)間吃午飯?
2)often(50%)相當(dāng)于at times,意為“時(shí)常,經(jīng)?！?表示常常這樣,但不總是這樣,反義詞為seldom.如：
She often helps her mother with housework.放學(xué)后,她常常幫助母親做家務(wù).
We often go to see our teacher.我們經(jīng)常去看望我們的老師.太給力了，你的回答已經(jīng)完美的解決了我問題！
