舉幾個before的翻譯句子例子？
before：之前的意思 before dinner,we watch TV at eight o'clock. before lunch,l usually read a story book. l do my homework before afternoon. 應該夠了吧？不夠再找我！給你翻譯吧： 1.晚飯之前，我們在8:00看電視。
2.午飯之前，我通常讀一本故事書 3.我在下午之前做作業。
before後麵要加句子嗎？
before要注意主句和從句的時間關係.當主句用將來時，從句總是用現在時；從句用過去時，則主句多用過去完成時，以此來體現動作發生的先後順序。
after表示主句動作發生在從句動作之後，主句和從句的時間關係正好與before相反例句after1. My undergrad electrical engineering knowledge is quite dated after all these years.我大學學到的電子工程知識經過這些年已經過時了。
2.After that, it is often downhill.這之後，就常常是走下坡路了。
3.But after that things started to go wrong.但是，自此以後，事情就開始變得不對勁兒了。
4.What did you do after you left washington?卸任後你在做什麼？before1.My undergrad electrical engineering knowledge is quite dated after all these years.我大學學到的電子工程知識經過這些年已經過時了。
