英语语法:短语first and foremost, for certain的用法副词短语在句中的功能相当于副词,通常在句中作定语、表语或者状语。
49. first and foremost首要,比什么都重要用法:first and foremost通常置于句首,起强调作用,表示后面说的话很重要。
类似的词组还有above all。
例句:First and foremost, they will look into the problem of bribery in the company.首先,他们会调查这个公司的受贿问题。
结构分析:First and foremost是状语, they是主语,willlook into是谓语动词(将来一般时),the problem of bribery in the company是宾语,其中of bribery是后置定语,in the company是介词词组作后置定语,修饰the problem of bribery。
50. for certain确定地,无疑地用法:for certain一般用来修饰动词。
类似的词组还有without doubt。
例句:I don’t know for certain why Carl Dadisman, the owner, wouldn’t stop Daddy from sitting down. (20XX年12月四级)我不知道为什么这个主人,卡尔·达迪斯曼,没有阻止爸爸坐下来。
