一、本课要点
二、核心词汇(23)
词条释义 / 讲解
dismayinglyadv. 令人沮丧地。源自dismay(使灰心),此处形容太空的寂静让人失望。
uneventfuladj. 平淡无奇的,无重要事件发生的。un-(不)+ event(事件)+ -ful。
detritusn. 碎片,碎屑。指岩石风化或磨损后留下的小石块或尘埃。
neighborly intervals近邻般的间隔。指挂图中行星靠得极近,如同邻居一样,与真实宇宙距离不符。
cast shadows投射阴影。cast shadow over... 指物体遮挡光线,在另一物体上形成阴影。
necessary deceit必要的欺骗。指数学上为展示全貌而牺牲真实比例的示意图,虽不真实但必要。
way beyondfar beyond,远远超出。way作程度副词,强调距离或程度之远。
further vs. fartherfarther指具体物理距离更远;further指抽象程度进一步。如:investigate further(进一步调查)。
in practical terms实际上,从实际操作角度。in fact的同义替换,强调现实可行性。
come close接近,靠近。此处指无法接近真实比例。come close to doing sth. 差点做某事。
diagram示意图,图解。侧重展示结构、关系或原理,不同于写实图片(map/illustration)。
diameter直径。简称D。对应半径radius(R)。地球直径缩小至豌豆大。
bacterium细菌(单数)。复数bacteria。此处形容冥王星按比例缩小后极小,肉眼难辨。
Centaur半人马(希腊神话生物)。本课指半人马座(Constellation Centaurus)。
Proxima邻近的。Proxima Centauri 即“比邻星”,离太阳最近的恒星。
Molecule分子。物质中能独立存在并保持化学性质的最小单元,如水分子 H2O。
Skin tanning皮肤晒黑。Tan 作名词指晒后的古铜色/棕色,常含健康或美观意味。
Little more than几乎只是,不过是。等同于 merely 或 only,用于降低事物的重要性或程度。
lonely void孤寂的虚空。void指完全空无一物的空间,形容宇宙的荒凉与空旷。
far apart相距甚远。形容天体之间巨大的距离间隔,强调空间的稀疏性。
well needed极度缺乏。此处为反语或强调,指空间极度空旷,物质极度稀缺。
stately manner庄严/缓慢的姿态。stately形容庄重、缓慢且威严的样子,描绘彗星运行的优雅迟缓。
comets彗星。太阳系小天体,由冰、尘埃组成,接近太阳时形成明亮彗尾。
三、句型与语法点(5)
要点说明
drawn to scale按比例绘制的。scale在此指“比例尺”。remotely drawn to scale意为“完全没有按比例”。
times...than倍数比较句型:A is five times farther from B than B is from C. 前者距离是后者的五倍。
as...as...同级比较结构。as small as... 意为“像……一样小”,此处用于夸张比喻。
虚拟语气与现在事实相反:If + 过去式 (shrank/was), 主句 would + 动词原形。
so...that...如此……以至于……。so far that the sun has shrunk... 表示距离之远导致的结果。
四、课堂讨论题
1. 老师,讲稿里说太阳系里的可见物质只占空间的“一兆分之一”,这个“一兆”到底是多少啊?这么小的比例是不是意味着太空真的啥都没有?
2. 为什么老师说是“必要的欺骗”(necessary deceit)?既然挂图上的行星挨得很近是不真实的,为什么还要这样画,不画真实距离行吗?
3. 讲稿里提到木星和海王星的距离,还有木星和地球的距离,说海王星离木星是木星离地球的五倍。这个“五倍”在图上为什么看起来没那么大?
4. 老师,farther和further都能表示“更远”或“进一步”,讲稿里说further可以指抽象的(比如调查案件),farther指具体的距离。能再多举几个例子让我彻底分清吗?
5. 如果地球缩小到豌豆那么大,木星要在300米外,冥王星在一英里半外,那如果我们把地球放大到篮球那么大,冥王星会在哪里?这样想是不是更容易理解太阳系的空旷?
五、Discussion Questions (English)
1. Teacher, the script says visible matter in the solar system only takes up 'one trillionth' of space. How big is a trillion? Does this tiny proportion mean space is really empty?
2. Why does the teacher call the solar system maps a 'necessary deceit'? If the planets being close together on the chart is untrue, why draw it that way? Can't we just draw the real distances?
3. The script mentions that Neptune is five times farther from Jupiter than Jupiter is from Earth. Why does this 'five times' distance look much smaller on the diagram than it actually is?
4. Teacher, both 'farther' and 'further' mean 'more distant' or 'to a greater degree'. The script says 'further' can be abstract (like investigating a case) while 'farther' is for physical distance. Can you give more examples to help me distinguish them clearly?
5. If Earth were shrunk to the size of a pea and Jupiter was 300 meters away, where would Pluto be? What if we enlarged Earth to the size of a basketball instead? Would that help us better understand how empty the solar system is?

七、课堂练习(AI 生成)
1. 在描述“进一步调查某项科学数据”时,下列哪个英文短语最符合材料中的用法?
A. investigate farther
B. investigate further
C. investigate far apart
D. investigate well needed
答案:B · 根据材料,farther指具体物理距离,further指抽象程度进一步,故调查数据应用further。
2. 材料中提到的倍数比较句型“A is five times farther from B than B is from C”主要表达什么含义?
A. A到B的距离是B到C距离的五倍
B. A到B的距离比B到C近五倍
C. A和B之间的距离是C到D的五倍
D. A、B、C三点构成五倍三角形
答案:A · 该句型为标准的倍数比较结构,表示前者距离是后者的五倍。
3. 在展示太阳系行星位置时,挂图常采用“necessary deceit”(必要的欺骗),这主要是因为:
A. 真实宇宙距离太远,按比例绘制会无法看清
B. 科学家故意伪造数据以误导学生
C. 行星之间的引力关系需要数学计算
D. 示意图必须使用鲜艳的颜色标注
答案:A · 材料指出“必要的欺骗”指数学上为展示全貌而牺牲真实比例的示意图,因真实距离过大无法按比例呈现。
4. 句子“so far that the sun has shrunk...”中使用了“so...that...”结构,该结构在材料中的功能是:
A. 表示同级比较,意为“像……一样”
B. 表示程度与结果,意为“如此……以至于……”
C. 表示虚拟语气,与现在事实相反
D. 表示倍数关系,强调距离之远
答案:B · 材料明确标注so...that...为“如此……以至于……”结构,用于表示距离之远导致的结果。
5. 根据板书中的“词源小贴”,asteroid(小行星)与asterisk(星号)的共同词源是希腊语中的哪个词?
A. event
B. scale
C. aster
D. void
答案:C · 材料明确指出两者均源自希腊语aster(星星),属于同源词。
