It's been raining for two days.The ground is very wet.
前句用現(xiàn)在完成進(jìn)行時(shí),表示兩天前雨就在下,一直下到今天,并且可能繼續(xù).為什么？那It is raining these days.是不是要改成It has been raining these days表示前些天雨就在下，一直下到今天，并且可能繼續(xù)注意時(shí)間狀語(yǔ)是for +“段”時(shí)間，these days 當(dāng)然要用進(jìn)行時(shí)了，是表示這段時(shí)間正在發(fā)生的動(dòng)作或存在的狀態(tài)。那It has been raining these days這句話是錯(cuò)的哦？It has rained these days這句更加是錯(cuò)的？是的，各個(gè)時(shí)態(tài)有各個(gè)時(shí)態(tài)相應(yīng)的時(shí)間狀語(yǔ)沒(méi)錯(cuò)啊。googe 搜索可以找到很多這兩種用法別人甚至在問(wèn)It has been raining these days 和 It has rained these days 的區(qū)別只能解釋到這里，不敢誤人。。
