step6典題賞析
(1)–what a nice bike! how long _______ you _______ it?
-just two weeks.
a.will ,buy b. did ,buy c.are, having d. have , had
解題：選d。buy是非延續(xù)性動詞，不能用于上述持續(xù)一段時間的結(jié)構(gòu)中。依據(jù)句意，just two weeks表示一段時間，是完成時態(tài)標(biāo)志，故排除c。
(2) i’ve been collecting coins ________ i was 10 years old.
a.when b.while c.and d.since
解題:本題為現(xiàn)在完成時，i was 10 years old又表示過去的時間點，故選d
【當(dāng)堂達(dá)標(biāo)】
