连词和介词的区别
发布时间:2022-05-13 18:07:26随着科技的进步”、“随着社会的发展”,这样的句子在作文中很常见,而且很有可能出现在文章的开头。但是,以下的句子是错误的:
As the development of science and technology ...
而以下的两句话是正确的:
With the development of science and technology ...
As science and technology develop ...
在这里,with和as有什么区别呢?这个和词性有关,with是介词,而介词后面跟名词【组】;as是连词,而连词后面跟句子。这就解释了为什么because后面跟句子,而because of后面跟名词【组】。有人可能提出疑问,为什么as a student这种表达方式是对的,as后面不是跟句子么?在这里,as表示“作为”,是介词;而as做连词的时候,有“随着”、“当”、“像”、“因为”等意思。
类似的,though和despite也是这个区别,前者是连词,而后者是介词。同理,以下两句话都是对的:
Many people do not like bus, because / as / since / for it is slow and crowded.
Many people do not like bus, because of / due to / owing to / for its slow speed and crowdedness.
很明显可以看出,because / as / since是连词,连词后面跟句子;because of / due to / owing to是介词,介词后面跟名词【组】;for表示“因为”的时候既可以做连词也可以做介词。
