看！这里的everyday和every day没有什麽区别呀！！！

所以说呢 第二句中应该是every day, 不是everyday
everyday只有形容词的用法
而every day 副词
-------------
思考，every day 可以做形容词？我觉得只能做副词...
-------
根据longman
单词 everyday [only before noun]
ordinary, usual, or happening every day:
例句 the problems of everyday life
wearing everyday clothes
a simple, everyday object
Describe it in ordinary everyday language.
注意! Do not confuse with every day (=each day) 不要和every day（=each day）搞混
例句I see him every day.
---
词组 every day
a) used to say how often something happens
every day/week/month etc (=at least once on each day, in each week etc)
例句They see each other every day.
Richard visits his mother every week.

everyday 日常的
every day 每一的，每一天的

这样最好理解了，我一开始也分不清楚，最后老师说了这句话后我就记住了！

把分给我吧 你不会后悔的~THANKS YOU!

everyday 形容词 “ 每天的”意思
every day 副词 “每天 ”

everyday “ 每天的”
every day “每天 ”
