 ♣ big, great, large
　这三个词都可表示“大”，常可互换。例如“一棵大树”可说a big tree，也可以说a large tree，还可以说a great tree. 其区别在于：
1. big常用于体积、程度、分量；large常用于面积、范围、数量；而great带有强烈的感情色彩，只可用于抽象事物。例如：
　The sun is a big ball of fire.　太阳是个巨大的火球。
　There is a large hall in the middle of the school campus.　校园中间有个大厅。
　The great animal crept slowly towards me.　这庞然大物慢慢向我爬来。
　He has made great progress.　他取得了很大进步。
2. 修饰人时，这三个词含义不同：big指长大或大人物， large指高大肥胖，而great则指（伟）大。例如：
　She is a big girl.　她现在是个大姑娘了。
　He's the greatest man I've ever seen.　他是我见过的最伟大的人物。
　She is a large woman.　她是个高大的女人。
3. 在语气上， big比large通俗；great比large感情色彩浓。
4. big和great常可用来加强语气，表示强烈的感情。它们可以和别的形容词连用，也可以彼此连用。例如：
　You great age!　您真是高龄！
　You big fool!　你真是个大傻瓜！
　Move your great big smelly feet!　拿开你的臭脚！
　注意只能说great big，不能说big great.
5. 如将“大小”相对，可说big and little, large and small, great and little〔small〕。
 ♣ 下面各组中短语的意思不同：

1. big有时还可以作“慷慨的”“美好的”“精彩的”解。例如：
　American people are known for their big hearts.　美国人以慷慨出名。
　They were very nice and we had a big night.　他们对人很好，我们度过了一个美好的夜晚。
　It was just so big, it was hard to take it all in.　简直太精彩了，要慢慢品尝才能欣赏得到。
2. 在口语里， big可以用在名字前（但不可以用在姓前）作为称呼语，表示亲热，相当于汉语中的“老兄”，但其首字母要大写。例如Big Ade（艾德老兄）。
3. big有时在俚语里也可用作副词，意为“自大地”“大量地”“勇敢地”。例如：
　Don't talk big.　别说大话。
　Don't think too big.　不要想入非非。
　Don't eat big in the evening.　晚上别吃得太饱。
　She took her defeat big.　她不因失败而气馁。
