题目解答
答案
根据in the past few years,可知时态是现在完成时have/has+过去分词.主语we接have.
故选:C。
故选:C。
解析
步骤 1:确定时态
根据句子中的时间状语"in the past few years",可以判断出句子应该使用现在完成时,因为现在完成时通常用来表示过去发生的动作对现在造成的影响或结果,或者表示过去开始并持续到现在的情况。
步骤 2:选择正确的动词形式
现在完成时的结构是"have/has + 过去分词"。主语是"we",所以助动词应该用"have"。动词"plant"的过去分词是"planted"。
步骤 3:验证答案
将"have planted"代入句子中,句子变为"We have planted a lot of trees in the past few years.",符合语法和语义要求。
