选择题
— Mum, could you buy me a dress like this?
— Certainly, we can buy ________ one than this, but ________ this.
A. a better; better than B. a worse; as good as
C. a cheaper; as good as D a more important; good as
答案
C
题目分析：考查形容词用法。本题的关键在于But表示转折。句意：—妈妈，我可以穿这样的一件衣服吗？—当然。我们可以买一件更便宜的，但是和这件一样好。As…as…与…一样；根据句意说明C正确。
点评：形容词的用法考查集中在比较级的考查，本题中要注意as…as…中用形容词的原级，另外根据句中的but说明前后有转折的关系。
