Question

---Where was your sister at this time yesterday evening ?
---She was writing an e-mail ______ I was watching TV at home.

A．a(chǎn)fter

B．a(chǎn)s soon as

C．while

D．until

Answer 1

C

試題分析：after在……之后；as soon as 一……就……；while當(dāng)……時(shí)，強(qiáng)調(diào)兩個(gè)動(dòng)作同時(shí)發(fā)生；until直到，常和not搭配使用。結(jié)合上文可知下文句意為：當(dāng)我在家看電視時(shí)，她正在寫(xiě)電子郵件。故選C。
點(diǎn)評(píng)：解答此類(lèi)題型首先要直到每個(gè)連詞的基本用法，然后結(jié)合上下文關(guān)系選擇合適連詞，故平時(shí)加強(qiáng)閱讀分析能力是很必要的。
