C
I am Planet Earth. I am the third planet from the sun. The sun gives me heat and light. I can support life!
I am a planet you can trust. I have all the things life needs—land, water, air, and energy from the sun.
I have four oceans and seven huge pieces of land. On land, I even have lakes and rivers. They offer plants and animals fresh water.
I rotate(自转), so all living things have day and night.
Because I am round like a ball, sunlight hits me unevenly(不均地). This makes parts of me hot and parts of me cold.
Oh, I almost forgot. I am tilted(倾斜的) too. This creates seasons. In January, my northern half is away from the sun. That’s winter. At the same time, the southern half is near the sun. It’s summer there.
I am a fair planet. I give seasons and sunlight to both the south and the north. They just get it at different times of year.
()49. Which paragraph tells the different landscapes on Earth?
A. Paragraph 1. B. Paragraph 2. C. Paragraph 3. D. Paragraph 4.
()50. Why do living things on Earth have day and night?
A. The Earth rotates. B. The Earth is round.
C. The Earth moves. D. The Earth is tilted.
()51. What does the underlined word “fair” in the last paragraph mean in Chinese?

C. 大度的 D. 公平的
()52. What is the best title for the passage?
A. Hello from the Earth B. I Love the Wonderful Earth
C. Tips from the Earth D. Please Respect the Earth

49. C 【解析】段落大意题。根据文章第三段“I have four oceans and seven huge pieces of land...They offer plants and animals fresh water.”可知,第三段提到四大洋、七大洲,陆地上有湖泊、河流,此处详细描述地球的地貌(海洋、陆地、湖泊、河流),符合“different landscapes(不同地貌)”,故选 C。
50. A 【解析】细节理解题。根据文章第四段“I rotate, so all living things have day and night.”可知,昼夜是由地球自转直接引起的,故选 A。
51. D 【解析】词义猜测题。根据最后一段“I give seasons and sunlight to both the south and the north. They just get it at different times of year.”可推知,地球给南北半球的“季节、阳光”是均衡的,只是时间有差异,因此“fair”强调地球对南北半球的公平分配,对应中文“公平的”,故选 D。
52. A 【解析】标题归纳题。文章以“I am Planet Earth(我是地球)”开篇,用第一人称自述地球的基本特征(位置、环境、自转、公转影响等),是地球向读者打招呼、介绍自己。因此 A 选项符合主旨,故选 A。

【分析】
这是一篇以第一人称介绍地球的英语阅读理解题，共4道小题，分别考查段落大意、细节理解、词义猜测和标题归纳。解题思路如下：1. 第49题需定位描述地球不同地貌的段落，明确各段落核心内容；2. 第50题需根据题干关键词“day and night”定位原文，查找昼夜形成的原因；3. 第51题需结合最后一段上下文语境，推测划线词“fair”的含义；4. 第52题需梳理文章整体结构和主旨，提炼最贴合的标题。

D
Your dog waves his tail to welcome you home. You may say, "My dog is so smart!" But how smart are animals?
People once thought animals didn't think. If they were hungry, they ate. If they were thirsty, they drank. If they were cold, they sat in the sun. If they were hot, they looked for cool places.
Now we know differently. Alex is a parrot. He likes to talk! He can speak almost 100 English words. He can count to six. He even knows what the numbers mean. He learns shapes and colours and can tell them apart. Alex works hard to say words correctly. He can also correct other parrots when they don't say the words clearly enough!
Parrots aren't the only smart animals. Ravens can solve puzzles(谜题). They can get fish from fishermen. Monkeys also talk to one another. They use sounds to tell other monkeys who they are.
Elephants can remember things for a long time. They also have other amazing skills. Like humans, they can look in mirrors(镜子) and know they are seeing themselves!
So, how smart are animals? The answer is "smarter than you think".
()53. In which part of a magazine can we probably see this passage?

()54. What can Alex do?

53. D 【解析】文章出处题。根据文章内容可知,全文围绕动物的智慧展开,列举了鹦鹉、渡鸦、猴子和大象的智慧行为。这类主题通常出现在与自然相关的杂志栏目中,故选 D。54. B 【解析】细节理解题。根据“He can speak almost 100 English words...He learns shapes and colours and can tell them apart.”可知,Alex 可以区分形状和颜色,故选 B。55. B 【解析】代词指代题。根据“Ravens can solve puzzles. They can get fish from fishermen.”可知,前一句主语是“Ravens(渡鸦)”,所以画线词“They”指代前句主语“Ravens”,故选 B。56. C 【解析】主旨大意题。文章开篇以“狗摇尾巴”引出“动物有多聪明”,接着用鹦鹉、渡鸦、猴子、大象等例子,说明动物的智慧,结尾“smarter than you think(比你想象得更聪明)”直接点明主旨。C 选项“动物是聪明的”是核心主题,故选 C。

【分析】
本题为英语阅读理解题，共4道小题，分别考查文章出处、细节理解、代词指代和主旨大意。解题思路：1. 第53题需根据文章主题判断所属杂志栏目，全文围绕动物智慧展开，属于自然类内容；2. 第54题需定位文中关于鹦鹉Alex的描述，逐一核对选项；3. 第55题代词通常指代前文出现的名词，定位第4段前句主语即可确定指代对象；4. 第56题需梳理全文结构，从开头引出问题、中间举例、结尾点明主旨来总结核心。
【解析】
53. 文章出处题：文章围绕动物的智慧展开，介绍了鹦鹉、渡鸦等多种动物的聪明行为，这类与自然生物相关的内容通常出现在杂志的“Nature（自然）”栏目，故选D。

55. 代词指代题：第4段前句主语是“Ravens（渡鸦）”，后句“They can get fish from fishermen.”中的“They”指代前文的“Ravens”，故选B。
56. 主旨大意题：文章以“狗摇尾巴”引出“动物有多聪明”的问题，中间列举多种动物的智慧表现，结尾点明“smarter than you think”，核心主旨是动物是聪明的，故选C。
