5.______,we went home straight away.
A.The job has been finished B.The job be finished
C.The job finished D.We have finished the job
答案C。这种句型是什么

第一题 我觉得要看明白句子的主干 C选项的主干实际是 all these days  , last few只是用来修饰days的 其他选项则是顺序混乱 不按语法来了
第二题 我觉得是倒装的知识
第三题 仔细体会意思  since主要意思 自...以来  放在文中也说的过去 但是因为AS的意思要更合适  所以首选择AS
第四题 我看的意思是:无论孩子想要什么就给他们什么是通常被看为不明智的.
              按句子单词翻译:它通常是考虑不明智的给孩子,无论他或她想要的什么东西.
第五题 首先根据后面确定时态 就是简单的过去时 就可把两个完成时排除 逗号后面的句子不缺结构 只选C就好了
