题目内容
3．假如新能源的使用更加广泛，环境污染将会大为减少．If new energyis used more widely，there will be much less pollution．
分析 is used more widely．
解答 答案：is used more widely．．这里是if引导的条件状语从句，遵循主将从现的规则，从句主语new energy是动词use使用的承受者，构成被动关系，故用一般现在时的被动语态am/is/are+过去分词，主语是不可数名词，故is used，广泛的用副词widely修饰动词use，表示更加广泛用比较级，widely是多音节单词，比较级是加上more，故答案是is used more widely．
点评 本题考查条件状语从句和被动语态的结合，还有比较级的呈现．
