by+年份,表示“到……年为止”
如:
by 2020 2020年之前
By + 时间表达式,用来暗示不迟于某个时间做完某事,也就是这个时间点是做完某事的最后时间,通常后面接确定的时间,如几点或星期几等,意为”不迟于“,
例如:
Guests must vacate their hotel rooms by 11 am.客人必须在上午11点前离开酒店房间。
Please send us the payment by tomorrow.请在明天之前把货款寄给我们。
They said that the plumber would be here by Monday.他们说水管工星期一会到。
The postman is always here by 11 am.
邮递员总是在上午11点以前到这儿。
此时的 by 与 before 的在时间上是有很大差别的,例如:
a. She has to submit her homework before Friday.
b. She has to submit her homework by Friday.
解析:句a的内在意思是作业最迟必须在星期四交上来,而句b的内在意思是作业必须在星期五午夜前交,两句差了12个小时,所以它们表示的截止时间还是有差距的,要认真使用,特别是在上级交代下属任务的时候。
!willing反义词是unwilling ,unwilling中文意思是adj. 不愿意的;不情愿的;勉强的
She is tough, unwilling to take no for an answer.她很难对付,不答应不肯罢休。
I was unwilling to submit to his orders and often punished by doing washing up.我当时不愿意服从他的命令而经常被罚洗碗。
被淘汰了。生活中说”pass”掉某人,是不考虑某人,被淘汰,尤其是在考虑人选时。一般情况下pass是通过,路过,递过来的意思。例如:pass the exam 通过了考试、pass by the shop路过商站、I didn't pass我考试没有通过。词性解释:pass 不及物动词 vi.
1、前进;通过;经过;超过You cannot pass. Stop where you are.你不能过去。原处停下。
2、(路)延伸;(消息)传开扩展资料:同义词辨析1、hand/ pass/ present /submit 【导航词义:递,交】hand v. 递交〔辨析〕指将某物亲手交给他人。〔例证〕He handed his composition to the teacher.2、他把作文交给了老师。pass v. 传递〔辨析〕指把某人可以看到但够不到的东西给某人。〔例证〕Pass me the paper, please.
surrender 是“投降、屈服”的意思; 另外一个,是 submit,意思是“不得已而屈服,屈从”的意思。
isset -- 检测变量是否设置判断post过来的数据是否被提交过来,if(isset($_POST["submit"]){ echo "提交过来了";}else{ echo "submit is no come~";}
