资源描述
Unit 2 Biggest,Longest,Widest1. I have been standing on one foot for more than three minutes. 我独脚站立已有三分多钟了。 more than 意为“超过、多余”,相当于over。如: I have more than one hundred books. 我有一百多本书。 more . than意为“比更”,more 后多接名词、多音节形容词或副词的原级。如: I have more books than Danny. 我的书比丹尼的多。 This film is more interesting than that one. 这部电影比那部更有趣。 2. The average blue whale is about four times as big as the biggest elephant. 一般的蓝鲸大约是最大的大象的四倍。 常见的表示倍数增加的句型: (1) A is n times as great (long,much,.) as B. (2) A is n times greater (longer, more,.) than B. (3) A is n times the size (length, amount,.) of B. 以上三句都应译为:A的大小(长度,数量,)是B的n倍,或A比B大(长,多,)n-1倍。如: This book is three times as long as (three times longer than / three times the length of ) that one. 这本书的篇幅是那本书的3倍(即长两倍)。 3. I was surprised to read about the man who pulled the train. (在报纸上)看到有人可以拉动火车我很惊讶。 (1) be surprised to do sth. 意为“很惊讶做某事”。如: I am surprised to meet an old friend in the street. 在街上遇到一位老朋友使我惊讶不已。 相关短语: to ones surprise 使某人惊奇的是 in surprise吃惊的 (2) 句中的who pulled the train 是定语从句,修饰先行词the man,意为“拉动火车的人”。 4. Thats very kind of you, but you cant mail cake in an envelope. 你真好,但是你不能用信封邮蛋糕。 赞扬某人善良、人品好时,在英语中一般不说You are very good / kind / nice. 而是说Its / Thats nice /good / kind of you. 在此句型中,如果表语是kind, nice, right, wrong, clever, polite 等描述行为者的性格、品质的形容词,则应在动词不定式前加上of sb.。如: Its clever of you to work out the math problem. 你真聪明,解出了这道数学题。 如果要说明动词不定式的动作是谁做的,可在动词不定式前加for sb.。如: Its difficult for us to finish the work. 对我们来说,完成这项工作很困难。 of sb. 和for sb. 这两种结构还有一个区别,在of sb. 结构中,可用sb. 直接作句子的主语来改写成“Its 形容词 of sb. 动词不定式”结构。试比较: Its foolish of him to go alone. (=He was foolish to go alone.) 他单独去太傻了。 for sb.结构则不能这样转换,如:Its difficult for us to finish the work.不可以说:We are difficult to finish the work.
