概念:

頻度副詞表示某一動作或狀態(tài)出現(xiàn)的頻率,即在一定時間內(nèi)某一動作或狀態(tài)重復出現(xiàn)的次數(shù)。頻度副詞的種類:1.表示具體的頻率、次數(shù)時,一次用once,兩次用twice,三次及以上用“基數(shù)詞＋times”。如:onceaweek(一周一次),fourtimesayear(一年四次);表示不太確定的頻率、次數(shù)時用twoorthreetimes(兩三次),fourtosixtimesaweek(一周四到六次)。2.不表示具體次數(shù)的頻度副詞。常見頻度副詞按頻率大小排列如下:always(100%)＞usually(80%)＞often(60%)＞sometimes(20%～40%)＞hardlyever(seldom)(20%)＞never(0%)頻度副詞的位置:一般用在實義動詞之前,be動詞、助動詞和情態(tài)動詞之后,有時為了強調(diào),也可置于句首。如:UsuallyIgotoschoolonfoot.我通常步行上學。對頻度副詞的提問:對頻度副詞的提問常用howoften,表示“多久一次”。Ⅰ.單項填空。()1.(2019·安徽中考)—Iwonder______the
