题目内容
14.________more attention,the trees would have grown better.( )A. | Given | B. | Being given | C. | Having given | D. | Give |
分析 (如果)多一些关注,这些树能长得更好.
解答 答案:A
解析:根据后一分句中的would have grown可知本句使用的是虚拟语气,故根据句意可知前一分句的完整形式是由if引导的条件状语从句:if they(the trees)had been given more attention.因为从句的主语与主句的主语一致,且从句中含有be动词(had been);故可以省略从句中的主语及be动词(以及if),而只保留动词的过去分词及其后的宾语.综上,本题答案为A选项.
点评 本题考查过去分词,做此类题目时一定要仔细分析句子结构,确定句子所缺成分以及该成分由什么来充当,再结合所给选项选出最终答案.
