句子有問(wèn)題,有兩個(gè)謂語(yǔ)動(dòng)詞.其中之一要改成非謂語(yǔ)動(dòng)詞.比如改成現(xiàn)在分詞的完成時(shí)：
there are many great changes having taken place in my hometown in the past ten years可不可以把having拿掉？ 即：there are many great changes taken place in my hometown in the past ten years. 這樣呢？不可以僅僅把having 拿掉，因?yàn)檫@里是現(xiàn)在分詞的完成時(shí)，表示“在過(guò)去十年中已經(jīng)發(fā)生的變化”。僅僅把 having拿掉，就變成過(guò)去分詞修飾changes，語(yǔ)態(tài)就錯(cuò)了。當(dāng)然原句改成從句也是可以的。
