You __D. needn’t have come _ all the way to meet me here. I know this place pretty well. A. don’t need to come B. needn’t come C. didn’t need to come D. needn’t have come need既助動詞（+v原形），又作實義動詞（+to+v），a,b,c僅從語法上看都對；don’t need to come， need作實意動詞，借助don't構成否定式， needn’t come ，need作助動詞，直接+not構成否定式，c項和a項相同，只是時態是過去時。本題用needn’t have come 表示虛擬語氣，與過去事實相反。

need作情態動詞常用于否定句中,后接現在完成時(need't have done),表示某人做了自己不該做的事need作情態動用于否定就寫為need't,不用don't need

"this place"說明已經在這里,已經帶我來了,所以選D 't need to do sth.2.need't do sth 3.need't have done sth.(意為:本不必做,但已經做了)
