【題目】It is said sending messages on QQ is sometimes not safe. You’d better use _________ USB drive to store the important materials.

A.aB.anC.theD./

【答案】A

【解析】

句意:據(jù)說(shuō)在QQ上發(fā)信息有時(shí)候是不安全的。你最好用一個(gè)U盤(pán)來(lái)儲(chǔ)存重要的資料。

考查冠詞。根據(jù)句意可知,空格處應(yīng)填入一個(gè)不定冠詞表泛指,CD選項(xiàng)可排除?崭裉幒USB中的U以輔音音素開(kāi)頭,故應(yīng)用不定冠詞a。故選A。
