基础浅层任务 1:图片匹配 P68 Ex1 答案
(1) space (2) the Earth (3) the Moon (4) spacesuit (5) spaceship (6) space station
基础浅层任务 2:旅行计划表格 P70 Ex1 标准答案
(1) the Moon
(2) 9:00 a.m. on 1 October 2053
(3) spaceship
(4) about three days
(5) weak gravity makes everything float; no air on the Moon, need spacesuit; must exercise every day
(6) walk on the Moon, jump high, collect moon rocks, take many photos
基础浅层任务 3:词义匹配 P71 Ex1
(1)—d (2)—c (3)—a (4)—e (5)—b
进阶理解问题链(日记行文逻辑 & 因果逻辑)
1. What’s the structure of Li Jun’s diary?
Para1: Excitement & departure plan;Para2: Space weak gravity problems;Para3: Moon’s low gravity & no air;Para4: Feeling & travel plans.
2. List 3 cause & effect sentences from the diary:
① Gravity is weak → things float around.
② No air on the Moon → must wear spacesuit to breathe.
③ Low gravity weakens bodies → people have to exercise daily.
3. What special facts about the Moon can we learn?
380,000 km from Earth; weaker gravity (lighter weight, jump high); no air, no sound; mysterious strange scenery.
深度思辨问题
Would you like to take a trip to the Moon? What challenges do you think you will meet?
(二)合作探究・小组活动突破(4 人互助小组)
活动 1:词汇分类 & 构词竞赛
1. 词汇分为天体名词、航天设备、太空环境形容词,口头造句;
2. 小组竞赛:用两个名词组合造复合名词(space + X)。
活动 2:双人对话任务(Before you read Ex2)
对话模板:
A: How do astronauts travel to the Moon?
B: They take a spaceship.
A: What can they do on the Moon?
B: They can walk, jump high and collect moon rocks.
活动 3:Your ideas 小组讨论
组员轮流分享是否想去月球旅行,用 because/so 说明理由,每组推选代表全班发言。
(三)迁移表达・分层输出
迁移 1:口头基础输出 —— 介绍月球旅行难点(不少于 4 句)
模板:
There is weak gravity in space, so everything floats. There is no air on the Moon, so we must wear spacesuits to breathe. We have to tie sleeping bags to walls because we will float away at night. We also need to exercise every day so our bodies won’t get weak.
迁移 2:双人综合问答对话(融合因果连词 + 全部太空词汇)
A: Why do things float inside the spaceship?
B: Because space gravity is very weak, so nothing stays down.
A: Why can’t we hear sounds on the Moon?
B: Because there is no air there, sound can’t travel.
A: What do you want to do if you go to the Moon?
B: I want to jump high and take lots of photos, because the Moon looks mysterious.
迁移 3:书面综合输出 —— 短文 My trip to the Moon
写作框架:
1. 开篇:出发时间、交通工具、目的地;
2. 第二段:太空失重环境带来的生活困难(漂浮睡觉、每日锻炼);
3. 第三段:月球环境特点(低重力、无空气、寂静无声);
4. 结尾:自己想在月球完成的活动,抒发感受。

课堂小结(课堂留白填写)
1. 核心阅读策略:cause and effect,连词______表原因,______表结果;
2. 构词法:复合名词 = 名词 + 名词,例:space + suit = spacesuit;
3. 太空 / 月球核心特点:弱重力物体漂浮、月球无空气需宇航服、月球重力小人体变轻、太空必须每日锻炼;
4. 核心名词:spaceship 飞船、spacesuit 宇航服、space station 空间站、gravity 重力。
当堂检测(5 分钟小测)
一、英汉互译

2. tie sleeping bags to the wall ________________
3. 复合名词:宇宙飞船 ________________
4. 在月球上呼吸 ________________
二、用 because /so 填空
