请解释journey,trip,travel,tour的区别

Voyage:一趟旅程,尤指海上之旅Many are finding that the most pleasant way to travel is a voyage on a cruise ship。许多人认为最痛快的旅行方式,是搭乘游轮,来一趟逐波之行。journey主要指单程较远距离的海、陆、空“旅行”,表示“去旅行”时,英语该说goon a journey,而不说go to a journeyMr。Smith made a journey from Paris to New York。史密斯先生作了一次从巴黎到纽约的旅行。A pleasant journey to you。祝你一路平安。travel一般指到国外或远方旅行,它同journey不同之处,在于不着重某一目的地,有到各地“游历”的意思,作名词时常用复数形式。He has just returned from his travels。他刚刚旅行回来One day in his travels in China,he got to Guangzhou。他在中国旅行期间,有一天他到达广州．trip常指短距离的,直达目的地的旅行,在日常用语中,trip可与journey通用。I am going on a trip to the seaside during the summer holidays。暑假期间我将去海边旅行。He went on a trip journey to Paris。他到巴黎旅行去了。tour“旅行,周游,观光”,主要目的地是游览或视察,距离可长可短,常带有“最后回到出发地”的含义。He is making a tour of the world。他周游世界去了。They spent two months on a tour through most of the countries of Europe。他们用了两个月的时间去旅行,游历了欧洲的大部分国家。
