Question

非谓语改错,
1.Having passed a post office,I stopped to buy some stamps.
2.The ground is covered with falling leaves.
Having passed a post office和 falling leaves这里感觉别扭,请帮忙给个正确的、合理的答复.

Answer 1

1.Having passed a post office,I stopped to buy some stamps.
原句的意思是“已经走过邮局以后,我停下来买了几张邮票.”
本句可以改写为：I Had passed a post office,I stopped to buy some stamps.
不难发现,邮票是在邮局买的,但是分词短语的完成形式 Having passed a post office,（已经走过了一个邮局）表示发生在“停下来买邮票”以前的动作时,显然分词所作的状语与主句的行为发生了矛盾,因此这个句子应该改为：
Passing a post office,I stopped to buy some stamps.(路过邮局的时候,我停下来买了几张邮票.)
2.The ground is covered with falling leaves.
现在分词作定语表示被修饰词正在发生的特征,因此 falling leaves 的意思是“正在落下的树叶”,这样就与前面的意思有了冲突,正落的树叶怎么回覆盖大地呢!
过去分词作定语表示被修饰词已经出现过的状态,如果把 falling leaves 改为 fallen leaves,意思就成了“已经落下的树叶”.“落叶”覆盖大地就符合逻辑了.
改正如下：
The ground is covered with fallen leaves.
