谁可以告诉我BUY 和PURCHASE的区别和这两个单词的语法知识?

若指用金钱去购买东西的话,两者意思是一样的.(1) buy 是最为普遍的用词,purchase 有时在较为官式的场合出现,比较上来得文化意味较重,而且似乎经过"深思熟虑"才决定的:"The board of directors has decided to purchase the land lot no.231 from xxx" 在此例子里,用 buy 完全不会影响其原意.(2) buy 和 purchase 例如你可 buy time (争取时间),I don't buy Tom's ida.我不采纳汤姆的意见.这时便不能换作purchase了.(3) buy 和 purchase 虽然都可作名词.但若是指一项「购入」则多用 purchase.buy 作名词用时多数作「抵到烂/执到宝...」解.We made the purchase last year (我们在上年达成这项购物/入的) It was a real buy at that price!(以那价钱来说真是抵到烂啦!) 至於deal with则多指安排,处理,涉及,做生意.可以用(make bussiness)、(cope with )、(manage)、(handle)、(see to)、(take care)、(sort out)、(content with)、(take in hand)等作同义词用.
