单选题 We were able to buy ______ furniture from ______ friend at cost price.

A. /; the
B. the; /
C. the; a
D. a; the

【正确答案】 C

【答案解析】[解析] 句意：我们能够用成本价从一个朋友处买到这个家具。本题考查的是冠词的用法。furniture是不可数名词，不能用不定冠词；friend是可数名词，可以用不定冠词。根据题意，故C正确。不定冠词a、an和定冠词the。不定冠词只能修饰可数名词单数，定冠词可以修饰所有的名词，起限定名词作用。例：(1)I have a dog and a cat.我有一只猫和一只狗。 (2)He didn't pass the exam, but he didn't want to tell his parents about the information.他没有通过考试，但是他不想告诉他父母这个消息。
