A. sometimes B. never C. always D. hardly C 考点二： 有些频度副词可放在句首或句尾，用来表示强调。never位于句首，句子要倒装。 eg: Never have I learnt this word. 我从未学过这个单词。 例题：Never ________(我能见到)this girl again. can I see 考点三： once, twice, three times…次数构成频率的表达方式 1)次数+a+时间（年／月／日／分……） 2)次数+ every+基数词+时间 （ 年／月／日／分……） Eg: once a year 每年一次 twice a month 每月两次 拓展：every two days=every other day 每两天 考点四： 对频度副词提问时，一般用 how often（多久一次）。 例题： —_____ do you go to movies? —Once a month. A. How often B. How far C. How long D. How soon A 辨析：how often 与 how many times how often多久一次，用来询问在某一段时间内进行某个动作的次数。how many times多少次，它不问动作发生的频率，只询问次数，即“多少”。其答语为once, twice, three times 等。eg: —How many times have you been to Beijing? —Only twice. —How often do you go to Beijing? —Twice a month. 辨析：hard与hardly 用法 例句 hard hard可作形容词或副词。作形容词时意为“艰难的；坚强的”。作副词时意为“努力地；长时间地；大量地”。 It rained hard last night. 昨天晚上雨下得很大。 hardly hardly是副词，意为“几乎不”，多和can连用。 I can hardly keep my eyes open. 我困得都快睁不开眼了。 辨析：everyday 和every day 用法 例句 every day 副词短语，作状语，意为“每天”，相当于each day。 He reads newspaper every day. everyday 形容词，只作定语，意为“日常的”，相当于daily。 The Internet has become part of our everyday life.
