语法：We can not go back to a Stone—Age existence of barter and living in huts.Stone—Age existence of barter and living in huts.这一块有语法错误吗?什么语法?为什么名词AGe后面还接名词.and 后面的ing又是怎么回事?

we can learn what we did not know we can learn what did we not know请问,这两句话语法对不对,求指教 can we go We can not go back later, is not already bound to the tragedy.是什么意思? We can not break up,we still have long way to go, We can not break WE CAN NOT SEE We can not go there because it is raining .(改为同义句） We can not go there _____ ______ the rain. i know we can not go banck anymore,l justi know we can not go banck anymore,l just couldn' let it we pull off hook,and can not go back on是什么意思? If you can love,do not let go,we have the next life, 填空:Whether we can go or not __________the weather(我们能否去还得看天气). we can not go fishing because it was raining hard .有错请改正 如何把we can not go out on school night改为被动语态 I think we can't go,but that does not represent i don't love you I still remember all that shaved in my heart.We all can not go bake. we,shopping,not,I,today,think,can,go,do 连词成句 We go,I can play..
