解析
【分析】先提取每张卡片的核心特征,再匹配对应天体:卡片1的核心是“恒星、提供光和热”,对应太阳;卡片2的核心是“旋转产生昼夜”,对应地球;卡片3的核心是“无空气水、宇航员可活动、夜晚可见”,对应月球,据此完成配对。
【解析】1. 卡片1描述的是能提供光和热的恒星,符合太阳(A)的特征,故填A;2. 卡片2提到旋转产生昼夜,这是地球自转的结果,对应地球(C),故填C;3. 卡片3描述的是无空气水、宇航员可行走且夜晚可见的天体,符合月球(B)的特征,故填B。
【答案】1.A 2.C 3.B
【知识点】天文常识 地球自转 月球特征
【点评】本题考查基础天文常识,结合天体的典型属性即可完成配对,难度较低,适合学生日常积累巩固。

二 给下列句子排序。
(
( 1 )Earth travels around the Sun.
(
(
(
(
4
)This tilt means different parts of Earth get different amounts of sunlight(阳光).( 1 )Earth travels around the Sun.
(
5
)When our part is tilted towards the Sun, it is summer.(
3
)But Earth is not straight up and down. It is tilted(倾斜的).(
2
)It takes one year to finish this trip.答案
4 1 5 3 2
解析
【分析】首先,英语句子排序需先确定逻辑起点,题目已明确标(1)的句子“Earth travels around the Sun.”为排序首句。接着找与首句衔接的句子:第五句“It takes one year to finish this trip.”中的“this trip”指代首句的“travels around the Sun”,故该句应排第2位。剩余句子中,第四句“But Earth is not straight up and down. It is tilted.”用转折引出地球的倾斜状态,承接前两句关于地球公转的内容,故排第3位。第一句“This tilt means different parts of Earth get different amounts of sunlight.”中的“This tilt”指代第四句的“tilted”,说明倾斜的影响,故排第4位。最后,第三句“When our part is tilted towards the Sun, it is summer.”承接前文的“不同阳光量”,说明倾斜带来的季节变化,故排第5位。因此各括号依次填4、1、5、3、2。
【解析】1. 确定首句:题目已给出标(1)的句子“Earth travels around the Sun.”,作为排序的起始句。2. 衔接首句:第五句“It takes one year to finish this trip.”中“this trip”指代首句的公转,故排第2位。3. 转折过渡:第四句“But Earth is not straight up and down. It is tilted.”转折说明地球的倾斜状态,承接公转内容,排第3位。4. 说明影响:第一句“This tilt means different parts of Earth get different amounts of sunlight.”中“This tilt”指代前文的倾斜,说明倾斜的影响,排第4位。5. 总结结果:第三句“When our part is tilted towards the Sun, it is summer.”承接前文的阳光差异,说明季节变化,排第5位。因此括号内依次填4、1、5、3、2。
【答案】4 1 5 3 2
【知识点】英语句子排序、逻辑衔接、指代关系
【点评】本题考查英语语篇的逻辑排序,需通过指代、上下文衔接判断句子顺序,能锻炼学生的英语理解与逻辑思维能力,难度适中。
