Question

–What was your brother doing at this time yesterday?
–He was reading a magazine ________ I was writing an e-mail at home.

A．a(chǎn)s soon as

B．a(chǎn)fter

C．until

D．while

Answer 1

D

考查連詞的用法。 as soon as“一……就……”； after“在……之后”； until“直到……”；
while“當……時候，和……同時”。由答語“他在讀雜志而我在寫電子郵件”可知，兩個動作同時進行，故選D。
