A．in ; on

B．on ; in

C．a(chǎn)t ; in

D．a(chǎn)t ;on

Answer 1

D

試題分析：在表示時(shí)間時(shí),in表示在一個(gè)時(shí)間范圍;at表示在具體時(shí)刻;on表示在具體某一天. two past eight是具體幾點(diǎn)鐘，故前面用介詞at。the morning of April 20^th.是具體的某一天，故用介詞on。選D。
點(diǎn)評(píng)：英語介詞的一個(gè)特點(diǎn)是一詞多義，并且介詞間語義交叉現(xiàn)象很多，習(xí)慣用法也很多，有時(shí)很難從詞義上區(qū)分開來。故學(xué)習(xí)中要注意不斷總結(jié)，熟記一些介詞和動(dòng)詞的固定搭配用法及習(xí)慣用法，是完成此類問題的捷徑。
