Practice
1. North America is a large continent, but it has only three main countries.北美洲是一个很大的州，但它只有三个主要的国家。
【辨析】large、big与huge
large、big与huge都是形容词，都有 “大的” 之意，但也有区别。
Language points
large large多指面积大。
注意：表示population(人口)或number(数量) 的 “多” 要用large，表示 “少” 要用small。
big big 指具体事物的体积大，其反义词是small/little。
huge huge强调体形巨大，而非重量。
例: China is a large country.
中国是个大国。
The population of China is the largest in the world.
中国的人口在世界上是最多的。
My apple is bigger than yours.
我的苹果比你的大。
A whale is a kind of huge animal.
鲸是一种巨型动物。
2. To the south of Canada is the United States.
加拿大的南面是美国。
(1)该句是一个完全倒装句。句子的主语是the United States，表语是to the south of Canada。在英语中，为了避免句子头重脚轻，结构不平衡，常采用倒装语序。
例: Japan is to the east of China. 日本在中国的东方。
Henan is on the south of Hebei.河南在河北的南方。
Handan is in the south of Hebei.邯郸在河北的南部。
to 表示 “在某范围之外的……方向”，两地互不归属，互不接壤。
on 表示 “在某范围之外的……方向”，两地互不归属，但接壤。
in 表示 “在某范围之内的……方向”，一地归属另一地。
(2)【辨析】to、on与in
to、on和in都可以表示方位，但在用法上有所不同。
3. Most speak English or French, but the third most common language is Chinese!大多数人讲英语或法语，而第三常用语言是汉语。
“the＋序数词＋形容词/副词最高级” 表示 “第几最……的”，后面接单数名词。
例: Steven is the second tallest boy in our class.
史蒂文是我们班第二高的男孩。
4. Mexico is smaller than both Canada and the U.S.
墨西哥比加拿大和美国都要小。
both…and… 意为“……和……(两者)都”。在句中可以连接两个并列的主语、谓语动词、宾语或状语等。它连接两个并列主语时，谓语动词要用复数形式。
例: Both my sister and I have been to Beijing.
我和我姐姐都去过北京。
