英语 辨析句子they have an Art Festival each yearthey have an Art Festival every year 有什么区别
every和each用法上的区别
1.each可作代词和形容词,而every只能用作形容词,如可以说each of these dictionaries或each one of these dictionaries,但不能说every of these dictionaries,该用every one of these dictionaries.
2.each可指两个或两个以上中间的每一个,而every只可指三个或三个以上中间的每一个,不能指两个中每一个.如：可以说each of my eyes,不可说every one of my eye但可说every one of my toes(脚趾) .
3.each通常用来指若干固定数目中的每一个,而every往往指“任何一个”如：Each girl sitting over there is my student.“坐在那里的每一女孩子”指若干固定数目中的每一个,故用each.Every man must do his best.“人人都尽最大的努力”泛指任何一个人,因而用every.
4.every和not连用,即“every…not”或“not…every”构成部分否定,表示“并非每一个”的意思,each则无此结构.
5.every+ 基数词+ 复数名词=every+ 序数词+ 单数名词,作“每(多少)”解,但each不能用于这一结构中.如：every three days 每三天或每隔两天,相当于 every third day.
6.every two days,every second day都作“每隔一天”解,但在实际应用中人们都用every other day来表示这一意思,every two days也有人讲,而every second day则少用的.
7.也可以说every few days,相当于汉语的“隔些日子”.
8.each 可以与other构成固定的搭配,即each other意思为“彼此、相互、互相”的意思,而every则不能.
*everyday 形容词：每天的,日常的,平常的,平凡的
everyday是形容词,后面可以直接跟名词,而every day是短语,一般作副词讲,放在句首或句末,用来修饰整个句子,every-day就有点画蛇添足了,不用这样来合成,不需要中间那个－,它的意思同everyday
例：a suit for everyday wear.
适合平日里穿的衣服
*every day 通常做“每天”解作状语时,省掉介词（in),表示频率.
I go to school every day.我每天上学
He exercises every day.他每天锻炼
