Jinan's post authority is seeking a ping-pong professional,arousing doubt that the job has been fixed in favor of someone.
英语语法书上不是说肯定句加doubt引导词用whether if ,但这句是肯定句,引导词却用了that（正确答案）,为什么?
答
doubt作动词的话,后面可以加定语从句啊,不管是whether if 还是 that which 等等,都可以加的,只是翻译不太一样,这个 I doubt that 什么什么就等于 I don‘t believe that...,（我不相信什么什么）相反地 I don't doub...
