课文中有but for some reason..reason不是可数名词吗? for some reason 的用法正确吗?新概念第二册Lesson21的课文上有这样一句话:The airport was built years ago,but for some reason it could not be used then.很奇怪for some reason的用法,reason不是可数名词吗,为什么不加s, 大哥大姐们 I am one of the few people left 这句话的left是离开的 还是留下的?Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The airport was built years ago, but for some rea 课文中：he asked a man for directions ,he said :'but can you tell me how to get to the pererson Building,'句子中 but 是印错了还是有其他什么解释,句子前有Excuse me but for some reason it could not be used then.but for some reason请问在句中作什么成份? 求一首歌词里有go looking for the summer time 的英文歌,女生唱的是女生唱的,节奏很轻快,不是Chris Rea的歌, but you have some n___ or some porridge and furit for your dinner I asked him for some ink,but he hadn't ____.(some any little more) 英语翻译some people simile and some people cry,some give up and some still try,some say hi but some say bye.some forget you but never do I,thanks for new year 请问一下为甚么在Excuse me for breaking in,____have some news for you.中,空格里要填but而不是yetbut 和yet在做连接词都有但是的意思,请问他们在表示转折时有什么区别吗 You may only be a person in this world , But for some youre the world .这句话是什么意思?有谁告诉我? for some 课文中有哪些顺序 这句英语句中BE的作用解释一下The airport was built during the war,but for some reason it could not be used then.这个BE是什么作用,不能省略吗?在好多英语句子中看到有BE,但是不知道什么情况下用BE,这时候BE又 He asked me for（ ）water,but I didn't have( ).A.some,some. B.some,any. C.any,some. D.any,any. he asked me for ( )paper,but i didn't have ( ) .a.some,some b.any,some c.some,any d.any,any 读句子,排顺序.（ ）But I want some new book.( )Hi,I'm Mike.I likes reading.( )Oh the weekend,I'm going to read books.( )So,I'm going to the bookstore at 3:00 on Sunday afternoon.( )Then,I'm going to stay at home with Amy.( )We're going to rea except for,except,beside,but for有什么区别
