【分析】
本题为英语补全对话题,需结合对话上下文的问答逻辑与语境匹配选项。先通读对话,明确话题围绕水力发电展开,再逐一分析每个空缺处的前后句,匹配对应的选项:第1空后Jason回答流水能发电,对应Leo的提问;第2空后Jason表达想了解发电原理,对应Leo的提问;第3空后Jason询问大坝发电,对应Leo提及大坝的内容;第4空回答大坝发电的方式;第5空对应提议进一步了解的内容。
【解析】
1. 第1空:Jason答“Running water can make electricity.”,说明Leo问的是关于水力发电的认知,对应选项C(What do you know about water power?),故1选C。
2. 第2空:Jason说想知道如何从水发电,说明Leo问的是还想了解的内容,对应选项D(What else do you want to know about it?),故2选D。
3. 第3空:Leo说“Look!”,后文Jason问大坝发电,说明Leo提到了大坝,对应选项B(The book says we use dams(大坝).),故3选B。
4. 第4空:Jason问大坝如何发电,需回答发电的具体过程,对应选项E(Water runs through the dams and turns big machines(机器).),故4选E。
5. 第5空:Jason提到从海获取能量,Leo回应“Cool!”后提议进一步了解,对应选项A(Let's learn more about it.),故5选A。
【答案】

三、提升题 Leo 和 Jason 弄明白了水是从哪里来的。请根据图片提示,将下列句子重新排序,还原水循环的过程。(首句已给出)
(
( 1 )When it's sunny, water at the top of the sea gets warm.
(
(
(

(
3
)When clouds hold enough water, it rains.( 1 )When it's sunny, water at the top of the sea gets warm.
(
5
)Water in rivers goes into the sea again.(
4
)When rain falls, water goes into rivers.(
2
)Some of the water goes up into the sky.答案
( 3 )When clouds hold enough water, it rains.
( 1 )When it's sunny, water at the top of the sea gets warm.
( 5 )Water in rivers goes into the sea again.
( 4 )When rain falls, water goes into rivers.
( 2 )Some of the water goes up into the sky.
解析
【分析】首先明确水循环的逻辑顺序,题目已给出首句(1):晴天时海面的水变暖。接下来,海面的水受热后会蒸发上升,对应句子“Some of the water goes up into the sky.”(第2句);水汽上升到天空形成云,当云聚集足够多的水汽时会降雨,对应句子“When clouds hold enough water, it rains.”(第3句);降雨后,雨水会流入河流,对应句子“When rain falls, water goes into rivers.”(第4句);最后河流中的水会再次流入大海,对应句子“Water in rivers goes into the sea again.”(第5句)。由此可确定各句的排序。
【解析】根据水循环的自然过程,结合给定首句的逻辑:
1. 首句(1):晴天海面水变暖,是水循环的起始条件;
2. 变暖的水蒸发上升,对应“Some of the water goes up into the sky.”,排序为2;
3. 水汽形成云后降雨,对应“When clouds hold enough water, it rains.”,排序为3;
4. 降雨后水流进河流,对应“When rain falls, water goes into rivers.”,排序为4;
5. 河流的水回到大海,对应“Water in rivers goes into the sea again.”,排序为5。
因此各句的正确排序为:3、1、5、4、2。
【答案】( 3 )When clouds hold enough water, it rains.
( 1 )When it's sunny, water at the top of the sea gets warm.
( 5 )Water in rivers goes into the sea again.
( 4 )When rain falls, water goes into rivers.
( 2 )Some of the water goes up into the sky.

【知识点】水循环、水的物态变化
【点评】本题通过图片辅助考查水循环的过程顺序,需要学生理解水在自然界的循环步骤,难度适中,能帮助学生巩固水循环的相关知识。
【难度系数】0.5
