Extend和expand都是英語單詞,它們的意思都是 “擴展、延伸”,但它們的用法和語義略微有些不同,因此我們需要區(qū)分記憶。
首先,extend是一個動詞,常常意味著向外延伸或擴大某個事物的范圍、長度、時間等等。例如:- The company decided to extend its sales promotion campaign for another month.(公司決定將其銷售促銷活動延長一個月。)- Please extend your legs and place your feet on the floor.(請把你的腿延伸開,腳放在地板上。)- We would like to extend our heartfelt thanks to all of you for your support.(我們想向大家表示由衷的感謝,感謝你們的支持。)而expand通常是描述某個事物被擴大或涵蓋更多的內容。例如:- The business plan calls for expanding into new markets within the next year.(這個商業(yè)計劃要求在未來一年內拓展新市場。)- The city has plans to expand its public transportation system.(這座城市計劃擴展其公共交通系統(tǒng)。)- His knowledge of history has expanded greatly since he began reading more.(自從開始閱讀更多以來,他對歷史的了解大大擴展了。)總之,記憶extend通常是指“延伸、伸出”,而expand通常是指“擴大、增加、拓展”。
