頻度副詞
1.定義
表示某一動作或狀態(tài)出現(xiàn)的頻率的副詞被稱為頻度副詞。
( 2 )表示具體頻率的頻度副詞短語:once/twice a week“一周一次/兩次”,four times a day“一天四次”,every day/week/year“每天/每星期/每年”等。
注意:表示三次或三次以上一般用“基數(shù)詞+times”來表示。
2.用法
( 1 )頻度副詞通常和一般現(xiàn)在時連用,表示在特定時間內(nèi)某動作或狀態(tài)出現(xiàn)的頻率。例如:
It often rains here in July.這里七月份經(jīng)常下雨。
I usually drink a glass of milk before sleep.我睡覺前通常會喝一杯牛奶。
( 2 )頻度副詞一般置于實義動詞之前,若句子里有情態(tài)動詞、助動詞或系動詞be,則放在這類動詞( 第一個 )的后面。sometimes可位于句首、句中或句尾。例如:
I’m hardly ever late for school.我上學幾乎從不遲到。
Sometimes we play games in class.有時我們在課堂上做游戲。
( 3 )對頻度副詞或“次數(shù)+時間段”提問時要用how often,意為“多久一次”,用于詢問某件事或某項活動發(fā)生的頻率。例如:
—How often does he go to the park?他多久去一次公園?
—He goes to the park three times a week.他一周去三次公園。
