which are conected 和which were connected有什么区别? There are also computers which are connected和which were conected 有什么区别? Which one are you 和 Which one you are哪个是对的? england和which city are 的中文是? Which beach do you usually go和Which beach are you going to no matter which stage we are in和no matter in which stage we are一样么 no matter which stage we are in和no matter in which stage we are一样么 Which dr.are You? which boys are there? which可不可以加are Which teams are plays? Which are your pens? which class are you ni和which class you are in 哪个对?我在一本书上面见到which class you are in?和 which class he is in?的用法。所以迷惑中。请帮我查实。 Which class are you in?和What class are you in的区别如题 谢谢 the days which are followed省略which 和be动词得来的 为什么可省略为什么which 和be动词可省略 变为 the days followed 英语语法there are different ways in which to address…这句话中in which和后面咋解释?举例 pumas are large,cat-like animals which are found in american.我想问的是which后面为什么加are 而不可pumas are large,cat-like animals which are found in american.我想问的是which后面为什么加are 而不可以直接found are和found which country are you in?
