学员疑问: 给我讲一下这个句子结构吧I do not wish to complicate the task more than is necessary是充当的什么成分呀
老师解答:more是副词much的比较级形式,做状语表程度修饰complicated the task,than is necessary是比较状语从句。这里的than is necessary也可以是than necessary。
点评分析:这里做一个拓展,比较状语从句因存在相同性质的比较对象,所以常会出现表达的重复,为避免这种情况的发生,比较状语从句中会经常使用替代和省略的手段,例如:
James enjoys the theater more than Susan enjoys the theater .(无省略或替代)
James enjoys the theater more than Susan enjoys it .(代词替代)
James enjoys the theater more than Susan does .(动词替代)
James enjoys the theater more than Susan.(省略谓语)
James enjoys the theater more.(省略从句)
提问句子中more than is necessary,可以理解为:I do not wish to complicate the task more than it is necessary to complicate the task.
