题目内容
10.The water is very serious in the lake now,so the government must prevent people from it.( )| A. | pollution;polluting | B. | pollution;to pollute | ||
| C. | pollution;pollution | D. | pollute;pollution |
分析 水污染已经相当严重了,所以政府必须阻止人们继续污染水源.
解答 答案:A,考察动词和名词辨析.在前面一句,缺少主语,所以不应该用动词pollute,而应该用名词pollution来表示"水污染",所以排除选项D.在后面一句话中,用到了固定短语"prevent sb from doing sth",译为"阻止某人做某事",所以应该填写动词ing形式,因此选择A.
点评 考察名词或动词的词形变化,应根据上下文及给定的动词或名词形式进行适当变换
