protect...from短语的意思是“保护……不受……的侵害”。from介词之后常跟对公众或社会整体影响不太大的普通词语。如果后面接较大的事件或较重要的东西,如战争、灾害、骚扰、税款等时,from多由against代替。如: I want to put on more clothes to protect myself from cold.我想多穿件衣服,以防受凉。 We should try our best to protect children from danger.我们应该尽力保护儿童免受危害。 prevent...from短语的意思是“阻止……的发生”。类似的短语还有stop...from,keep...from。当prevent/stop...from用于主动语态时,介词from可以省略,但当prevent/stop...from用于被动语态时,介词from不可以省略。如: The heavy snow prevented us from going out for sports.=The heavy snow prevented our going out for sports.大雪阻止了我们外出活动。 The shelter is built to prevent the goods from the sun.搭建棚子的目的是保护产品免受阳光照射。 嘿~顺便给你一个免费的英语学习软件吧 http://www.douban.com/note/73199884/挺有用的喔~嘿嘿~我自己也在用,还能自己增加生词的喔~有空就去下载来用用咯~
