Reading
The earth is a special planet. It is our home now, and it will be our home in the future.
But people can’t live everywhere on the earth. We can’t live in water.Oceans cover two thirds of the earth’s surface. The earth has only one big ocean, but we use these names for its different parts: the Pacific Ocean, the Indian Ocean, the Atlantic Ocean, and the Arctic Ocean.
Only about one third of our planet is land. There are seven continents: Asia, Africa, Oceania, Antarctica, Europe,
North America, and South America. Some land is rich with green forests,fresh water, and good soil. But some places are difficult for humans to live because of the snow and ice, the deserts, or the high mountains.
The earth is our only home. We must treat it well for our children and for our children’s children, too!

Language points

But people can’t live everywhere on the earth.
但人类无法在地球上的每个角落都生存。
on the earth含义:在地球上(侧重地点,earth 前面要加 the)
指我们居住的这个星球,属于方位短语。
例句:People live on the earth.
人类生活在地球上。
on earth含义:究竟、到底(用于疑问词后,加强语气,不加 the)常用搭配:what/who/where/how on earth…
例句:Where on earth did you find this bag?
你到底在哪里找到这个包的?
辨析小口诀
有 the 表地点:on the earth 在地球上
无 the 表强调:on earth 究竟,到底
2
Oceans cover two thirds of the earth’s surface.
海洋覆盖了地球表面的三分之二。
two thirds 三分之二
(1)分数表达规则
口诀:分子基数,分母序数;分子大于 1,分母加 s。
分子:基数词(one, two, three…)
分母:序数词(first, second, third…)
分子>1 → 分母变复数(加 s)
例:two thirds 三分之二;three fourths 四分之三
补充:分子为 1 时,分母不用复数:one fifth 五分之一
例句:Two thirds of the land is covered with trees.
三分之二的土地被树木覆盖。
(2)分数作主语:谓语看of 后面的名词(核心考点)
1. of + 可数名词复数 → 谓语动词用复数
例句:Two thirds of the books are new. 三分之二的书是新的。
2.of + 不可数名词 → 谓语动词用单数
例句:One fifth of the milk is bad.
五分之一的牛奶变质了。
3
Which continent is full of snow and ice all year round?
哪个大陆终年被冰雪覆盖?
be full of
含义:充满;装满,描述状态,主语人 / 物都可以,后接名词。
短语核心:full 是形容词,表示 “满的”,侧重呈现出来的状态。
例句:The box is full of old photos.
这个盒子里装满了老照片。
含义:被…… 装满,同样表状态,可和 be full of 互换。
fill 是动词 “装满”,be filled 是被动结构。
例句:The garden is filled with beautiful flowers.
= The garden is full of beautiful flowers.
花园里开满了漂亮的鲜花。
拓展:be filled with
辨析要点
1. be full of:主动描述满满的状态,没有被动含义
2. be filled with:被动形式,强调 “被填满” 这个结果
同义转换:A be full of B = A be filled with B
