Summarizing
Read the text and underline the important information, and then complete the summary.
The earth is our only home planet. It is neither too close nor too far from
the sun. This helps the earth get enough light and heat from the sun. The
earth is large, and it can hold the right type of air around it. Besides,
there is plenty of water as well as some dry land on the surface of the
earth. With water and land, people can live and grow food on the earth.

Exploring the Topic
一、Key Knowledge
Solar System Elements：Sun（star, diameter 1,391,400km... ）；Planets（inner: Mercury, Venus...; outer: Jupiter... ）
Classification：Inner planets（smaller, rocks/soil ）；Outer planets（larger, gas... ）
二、Reading Strategies
Comparing & Contrasting：Compare dimensions（type, size... ）→ Find differences/similarities
Summarizing：Identify topic sentences + key info → Short & clear summary
Language points
06
1. It may look yellow, orange, or even red, but its real color is white.中 “but” 连接 “太阳看起来的颜色” 和 “实际颜色” ，表转折 。
用 “and”（表并列 / 顺承 ）、“but”（表转折 ）连接两个简单句，合并成更丰富的句子。用 “and”“but” 把两句话合并（如 “Earth is a planet. It has life.” → “Earth is a planet and it has life.” ；“The Sun is big. It’s not a planet.” → “The Sun is big but it’s not a planet.” ）
2. “There is plenty of water as well as some dry land...”（地球表面有大量水和陆地 ）→ “plenty of water” 是不可数名词短语，用 “is” 。
“There be + 事物 + 地点 / 时间” ，表示 “某地 / 某时有某物” ，be 动词（is/are ）随后面名词单复数变。“There are no living things on the Sun.”（太阳上没有生命 ）→ 单数 / 复数？“living things” 是复数，所以用 “are” 。

Exercise
Please choose the correct answer from A, B, C.
1. The inner planets are ______ than the outer planets.
A. larger
B. smaller
C. bigger
D. farther
答案：B
解析：文中提到 “The inner planets are smaller and made of rocks and soil, while the outer planets are larger...” ，可知类地行星比类木行星小，“smaller” 符合，A 是更大（描述类木行星 ），C 表意类似但文本用 smaller，D 是更远（说距离 ），选 B。
2. ______ plenty of water on Earth’s surface.
A. There is
B. There are
C. There have
D. There has
答案：A
解析：“plenty of water” 中 water 是不可数名词，there be 句型里不可数名词作主语用 “there is” ；B 用于复数名词；C、D 是错误结构，英语用 “there be” 表存在，选 A。
Please choose the correct answer from A, B, C.
