13.-Don't eat too much candy,for it's_____ your teeth.-Oh,I get it.Thank you.( )
| A. | harm to | B. | harmful to | C. | badly to |
分析 --不要吃太多糖果,对你牙齿有害.
--我知道了,谢谢.
解答 答案:B,考察形容词辨析.分析句子结构,it's后边缺少的成分做表语,应该是形容词,所以排除C,badly是副词.此外,分析句子含义,该处表达的是对牙齿有害,固定搭配为do harm to和be harmful to,由于谓语动词是is,所以应该选择B.
点评 考察形容词辨析,应根据句子结构句及上下文含义进行选择
