1. consume:

① The developed countries consume the most energy in the world. 人教⑥ – 4
② Looking after the children, cooking and cleaning are time-consuming. 2008 四川改
? [正式用语] 吃光;喝光:

2.range
RANGE ROVER (路虎揽胜) 作为“越野车中的劳斯莱司”,是LAND ROVER的旗舰车型。

RANGE ROVER 背景
ROVER (罗孚) 是北欧的一个民族,LAND ROVER生产自行车时就使用罗孚作商标名。1904年生产汽车,仍以“罗孚”为车牌名。由于罗孚民族在历史上是一个勇敢善战的海盗民族,所以罗孚汽车商标采用了一艘海盗船,张开红帆象征着公司乘风破浪、所向披靡的大无畏精神。这个民族的特征其实也对应了rover的释义“漫游者”,那转移到车上,什么样的漫游者才算是刚劲的越野车呢?range的动词词源义是“在某一区域内活动”,RANGE ROVER则是指“在广阔区域漫游的越野车”,这与其中文名“路虎揽胜”正好契合。
range
mountain ranges 山脉
range
range的词源
range名词的词源义是指一排排的人,尤其是指猎人或者士兵,和动词的词源义密切相关,名词由动词而来,其基本义是“范围”。



a range of:一系列
a wide range of:范围广泛的
? [C] & [U] [常用单数] 范围;界限:
Most of the students are in the 16-19 age range.

The price was beyond our range, so we declined.
那个价格超出了我们能承受的范围,所以我们拒绝了。

? [C] & [U] 距离:
Do not miss this opportunity to see whales at close range on their annual migration south to the Antarctic.
不要错过近距离观看一年一度南下向南极洲迁徙的鲸群。 人教⑦ – 3











? [C] 山脉:
Between Italy and France, there is a mountain range
called the Alps.
在意大利和法国之间,是阿尔卑斯山脉。 外研③ – 1

in / within range (of) 在 (…的) 范围内
out of range (of) 超出 (…的) 范围














■ vi
? 包括:
The show had a large audience, ranging from children to grandparents.
这个节目受众很广,老少皆宜。

? (价格、水平、温度等) 处于某个范围之内:
The price ranges between $25 and $400.
价格在25美元到400美元之间。

3 average
如果对自己的英语水平做个评价,你的英语水平如何?
Excellent?Very good? Good? Fairly good? 还是 Average? 或者 Below average?
如果说你的水平中等偏上,该怎么表达?
average 词源
? average 形容词由名词而来。其基本义为“份额平等的”。
? 名词 average 的由来:古时候在没有保险机构的情况下,各位货主按各自货品价值分摊因遇海难或其他意外事故而遭受的损失,据此衍生出“平均分担”一义,而今天 average 的各项释义,如“平均数”、“平均水平”、“中等的”等都是由此衍生而来。

6 contribution
下面是2015年高考全国卷 I 阅读理解C篇中的一道题,当年难倒了一大批考生。

The fine selection of the major works was done in close collaboration (合作) with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg, Florida.

31. What does the word “contributions” in the last paragraph refer to?? A. Artworks. B. Projects. C. Donations. D. Documents.
【解析】根据前一句句意及关键词The fine selection of the major works,可推知contribution在文中的含义为“作品”。而高中生在英语学习中,最常接触到contribution的释义是“贡献”,如果以此释义来解释contribution,就会导致学生误选失分。
【答案】A
从上图所显示的查询结果可看出,四大版本教材的词汇表均未给出contribution作 “稿件;作品”之意。这就要求我们在词汇学习过程中,应该有意识地注意熟词生义,以备不时之需。

I admire Edison a lot because he made a great contribution to the world. 我很敬佩爱迪生,因为他为世界作出了巨大贡献。 2008 湖南书面表达改
