Earth is our home planet.
It was born 4.6 billion years ago. It is one of the eight planets of the solar system. It has a diameter of around 13,000 kilometers. The distance from Earth to the Sun is about 150 million kilometers, neither too close nor too far away. So it makes Earth neither too cold nor too hot, just right for us to live on.

Oceans cover about 71% of Earth. They provide plenty of water for us. With enough heat and water, Earth is a perfect place for us to live on. And there're many plants and animals on it.








Earth is our home. We must love it and protect it.

一、根据句意,从方框中选择适当的词并用其正确形式填空。
publish, prove, strange, freeze, amaze
1. Water
freezes
when the temperature is below 0℃.
2. Mr. Liu
published
his new novel about space exploration last month.
3. In the end, all the results

4. This photo about space is a(n)

5. I heard some
strange

答案

1. freezes 2. published 3. proved 4. amazing 5. strange

解析

【分析】
首先通读每个句子,明确句子所需的词性、时态,再结合方框中的词汇进行适当变形:1. 句子描述客观事实,主语water为不可数名词,需用一般现在时,动词用第三人称单数形式;2. 时间状语last month提示用一般过去时,动词用过去式;3. 语境体现过去的结果,需用一般过去时,结合prove to be结构;4. 修饰名词性短语work of art(指物),需用形容词,对应amaze的形容词形式;5. 修饰名词sound,需用形容词,直接选用方框中的形容词即可。
【解析】
1. 句意为“当温度低于0℃时,水结冰”,描述客观事实,主语water是第三人称单数,一般现在时中动词freeze变第三人称单数形式freezes;
2. 时间状语last month(上个月)提示用一般过去时,动词publish的过去式为published;
3. 句意为“最终,所有结果证明是错的”,语境为过去的情况,用prove的过去式proved,构成prove to be结构;
4. 修饰表示物的名词短语work of art,需用形容词,amaze的形容词amazing表示“令人惊奇的”,符合语境;
5. 修饰名词sound,需用形容词,方框中的strange(奇怪的)直接使用,符合句意“我晚上听到一些奇怪的声音,让我害怕”。
【答案】
1. freezes 2. published 3. proved 4. amazing 5. strange
【知识点】
动词时态变化、形容词用法、动词过去式
【点评】
本题为英语选词填空基础题型,考查学生结合句子时态、词性要求变形词汇的能力,难度适中,适合初中阶段学生练习。

【解析】
1. “出生于”的固定表达为be born in,句子描述过去的情况,主语Copernicus是第三人称单数,be动词用过去式was,故填was born in;
2. “在……的中心”的固定短语是at the center of,符合句意;
3. 固定句型“It takes sb some time to do sth”表示“做某事花费某人多少时间”,此处主语为it,故填It takes;
4. 句中出现比较级标志词than,需用形容词比较级,“a little”可修饰比较级表示程度,bright的比较级是brighter,故填a little brighter;
5. “so...that”引导结果状语从句,意为“如此……以至于”,符合句意,故填so; that;
【答案】
1. was born in 2. at the center of 3. It takes 4. a little brighter 5. so; that
