relevant
在英语写作中,学生普遍的做法是用自己熟悉或者自己最常用的词来表达观点或陈述事实,这样做常出现的问题是用词不够高级,过于朴实无华,甚至常常将正式用语与非正式用语、书面语与口语混用,从而影响了整体的写作水平,影响了书面表达的得分。因此,我们要想使自己的写作水平更上一层楼,使自己在高考写作中得到更理想的分数,就需要在平时的英语学习中增强正式用语与非正式用语、书面语与口语的意识,并在写作中根据文体合理用词,以使表达更精准、更地道。
本单元中的relevant属于高级词汇,更多地用于正式场合或正式文体中。
relevant R1 adj 有关的;贴切的:
relevant experience / information
(be) relevant to:
The sharing economy is increasingly relevant to our daily lives as well as to the global economy.
