也可以表示“在将来多少时间之内”,句子中的谓语动词要用一般将来时态;after常指以过去时间为起点的“一段时间之后”,所以它与过去时态连用。
当after指某个特定的未来时刻或日期之后,或指以将来某一时间为起点的若干时间之后时,它可以与将来时态连用。
例句:I'll be back in half an hour.我半小时后就回来本句中的in作"以后"解,不能用after代替。
after和in都可以表示"以后"的意思,其区别是:○1after以过去为起点,表示过去一段时间以后,常用于过去时态的句子。
Eg:They started working after lunch.他们是午餐后开始工作的。
○2in以现在为起点,表示将来一段时间以后,常用于将来时态的句子。
Eg:They will start working in half an hour.他们将在半小时后开始工作。

○3一般疑问句:将will/shall/be提到主语前面Will the students watch the match?学生们要去看比赛吗?Are you going to visit your friends?你要去看望你的朋友们吗?1)“will/shall+动词原形”表示单纯意义“将来要(会)……”,没有计划性。
They will go with us.他们将和我们一起去。
2)“be going to+动词原形”表示“将要发生……”“打算、计划、决定要……”。
What are you going to do next Sunday?下个星期日你打算做什么?○4there be句型的一般将来时1)there be句型的一般将来时的构成是“There will be+主语+其他”,意为“将会有……”。

Eg. The doctor lives in a village. He saved many lives.那位医生住在一个村子里。
他救了很多人。
Live-living adj. 活着的-alive adj.活着的-lively adj. 活泼的Living 与alive两者都是形容词,且意思都是活着的,不同之处为living 可作定语和表语,alive 只能作表语。
Living people 活着的人们此时不能用aliveEg. After so many years. He is still alive. 这么多年后,他还活着。
Lively虽然ly结尾,但词性不是副词,而是形容词。
