usually

常用用法

usually是頻度副詞,意思是“常?！薄傲?xí)慣於”,有遵循常槼的意思,其經(jīng)常性約爲(wèi)90％。
usually衹能用作狀語(yǔ),位於實(shí)義動(dòng)詞之前,系動(dòng)詞、助動(dòng)詞或情態(tài)動(dòng)詞之後,也可放在句首或句末表示強(qiáng)調(diào)。用於否定句時(shí),多位於實(shí)義動(dòng)詞與系動(dòng)詞、助動(dòng)詞或情態(tài)動(dòng)詞的中間
usually也可位於否定句之前,表示某事通常不會(huì)發(fā)生。

這四個(gè)詞意思相近。其區(qū)別是：
1.表示的頻率不同。例如：
He comes to school on Monday,Tuesday,Wednesday,Thursday,Friday,Saturday and even on Sunday.我們可說(shuō)：He always goes to school.always表示的頻率是100%。
He comes to school on Monday,Tuesday,Wednesday,Thursday and Friday.我們可說(shuō)：He usually goes to school.usually表示的頻率是90%。
He comes to school on Monday,Tuesday,Wednesday and Thursday.我們可說(shuō)：He often goes to school.often表示的頻率是60%。
He comes to school on Monday and Thursday.我們可以說(shuō)He sometimes goes to school.sometimes表示的頻率是20%。
2.always的反義詞是never; often的反義詞是seldom; usually的反義詞是occasionally, sometimes的反義詞是always。

這兩者都可表示“通常地”。其區(qū)別是：
usually 指經(jīng)常的行爲(wèi)或動(dòng)作; 而as usual指一次性的行爲(wèi)或動(dòng)作,意爲(wèi)“像往常一樣,照例”。試比較:
He usually goes to bed at ten o'clock.
通常他10點(diǎn)鍾上牀。
He went to bed at ten o'clock as usual today.
他今天像往常一樣10點(diǎn)鍾上牀。

這些副詞均表示頻度。
always縂是，永遠(yuǎn)。語(yǔ)氣最強(qiáng)，指在一切時(shí)候，沒(méi)有例外。
often經(jīng)常，語(yǔ)氣弱於always,側(cè)重動(dòng)作發(fā)生的次數(shù)具有經(jīng)常性，具躰時(shí)間意味不強(qiáng)。
usually通常，通例地，指習(xí)慣性動(dòng)作，頻度僅次於always，較often大，偶爾有間隔。
frequently時(shí)常，經(jīng)常，與often同義，可通用，但較正式，強(qiáng)調(diào)次數(shù)頻繁。
repeatedly屢次，強(qiáng)調(diào)次數(shù)多，但反複的頻率不一定均勻。
regularly用於脩飾經(jīng)常而有槼律性的動(dòng)作。
