二、核心词汇(7)
| 词条 | 释义 / 讲解 |
|---|
| instant | n. 瞬间。cracking instant 指极短的一刹那,cracking 为象声词,强调速度之快。 |
| endow with | v. 赋予,天生具有。常指上天或自然赋予人的特质,如天赋、美貌或智慧。 |
| light years across | phr. 跨度达……光年。across 表示宽度或直径,此处形容宇宙的浩瀚尺度。 |
| ungraspable | adj. 无法理解的,难以把握的。由 un-(不)+ grasp(理解/抓住)+ -able 构成。 |
| up to infinite | phr. 直至无限。infinite 在此作名词或形容词,表示没有上限的极大值。 |
| arrayed | adj. 排列整齐的,井然有序的。源自 arrange,perfectly arrayed 形容宇宙结构精密有序。 |
| undergo | v. 经历,遭受。undergo expansion 指经历膨胀过程,常用于描述科学变化或重大事件。 |
三、句型与语法点(1)
| 要点 | 说明 |
|---|
| Post-positive Adjective | 后置形容词。vast 置于 universe 之后,构成定语从句 a universe that was vast,以便后接具体数据说明其巨大。 |
四、课堂讨论题
1. 老师,讲稿里说宇宙在那一瞬间就拥有了一个“vast”的宇宙,为什么形容词vast不直接放在universe前面,非要后置呢?
2. 文中提到宇宙宽度“至少”是一千亿光年,但后面又说上限可能是无限大,既然不知道确切大小,为什么还要强调这个具体的数字呢?
3. 讲稿里用“perfectly arrayed”来形容宇宙,还特意解释了这是像“排兵布阵”一样整齐,这和普通的“arranged”有什么区别?
4. 为什么科学家会说关于大爆炸起因的那些问题(比如是否有永恒循环)非常接近宗教问题?这跟科学解释有什么关系?
5. 最后提到的“Goldilocks and the three bears”(金发姑娘与三只熊)这个故事,具体是怎么用来解释宇宙为什么“刚刚好”适合我们存在的?
五、Discussion Questions (English)
1. Why is the adjective 'vast' placed after 'universe' instead of directly in front of it as usual?
2. If the universe's size is unknown and could be infinite, why does the text emphasize the specific number of 'at least a hundred billion light years'?
3. How is 'perfectly arrayed' different from just 'arranged', especially since it's compared to military formation?
4. Why do scientists consider questions about the cause of the Big Bang, such as eternal cycles, to be close to religious questions?
5. How exactly does the story of 'Goldilocks and the three bears' explain why the universe is 'just right' for us?
六、听力 / 讲稿全文
1
00:00:09,730 --> 00:00:14,510
这么大的数字,这当然我们是无法想象,
2
00:00:14,530 --> 00:00:15,870
无法理解的。
3
00:00:41,590 --> 00:00:44,930
这样的一个数字显然无
4
00:00:44,990 --> 00:00:49,810
法理解那我们只要知道这一点就够了 It is enough to
5
00:00:49,810 --> 00:00:54,470
know that 只要知道这一点就够了我们只要知道 in a
6
00:00:54,470 --> 00:00:57,030
single cracking instantinstant means
7
00:00:57,030 --> 00:01:02,870
momentcracking 是一个象声词就是啪的一声那整个意
8
00:01:02,870 --> 00:01:08,350
思就是说在短暂的一瞬间 We were endowed with the
9
00:01:08,350 --> 00:01:13,410
universeendowed 是获得拥有的意思
10
00:01:13,950 --> 00:01:17,970
比如说 she was endowed with both good looks and brains
11
00:01:17,970 --> 00:01:23,910
那这种获得或者拥有往往都是指上天自然赋予你的东
12
00:01:23,910 --> 00:01:28,900
西她拥有就是她拥有与生俱来的
13
00:01:29,660 --> 00:01:36,440
她拥有天生就有好的外表和聪明的脑袋 so
14
00:01:37,940 --> 00:01:41,300
we were endowed with a universe 就那么瞬间,
15
00:01:41,360 --> 00:01:43,220
我们就拥有了一个宇宙,
16
00:01:43,340 --> 00:01:46,300
我们就拥有了一个巨大的宇宙,
17
00:01:46,420 --> 00:01:48,300
a universe that was vast,
18
00:01:48,740 --> 00:01:50,570
有多大呢?
19
00:01:50,630 --> 00:01:54,030
at least a hundred billion light years across,
20
00:01:54,410 --> 00:01:55,230
至
21
00:01:55,420 --> 00:01:55,900
少,
22
00:01:55,940 --> 00:02:00,840
它的这个宽度至少是 a hundred billion light years,
23
00:02:01,080 --> 00:02:03,460
billion 是亿,
24
00:02:04,460 --> 00:02:07,120
a hundred billion,一千亿,
25
00:02:07,160 --> 00:02:11,640
至少是一千亿光年,光年又是多大呢?
26
00:02:11,640 --> 00:02:16,380
就是光在一年走过的距离好了我觉得我们已经
27
00:02:16,920 --> 00:02:21,150
已经无法想象了这里面这里少到一个 billion 少了一
28
00:02:21,150 --> 00:02:24,420
个 trillion 我觉得对我们都已经没有关系了反正都是
29
00:02:24,420 --> 00:02:28,040
一个根本就 ungraspable number
30
00:02:29,420 --> 00:02:33,940
好现在大家可以看一下注意一下 that was vast a
31
00:02:33,940 --> 00:02:36,160
universe that was vast
32
00:02:36,570 --> 00:02:41,950
为什么 vast 不放在 universe 的前面就直接说
33
00:02:45,670 --> 00:02:46,070
正
34
00:02:47,220 --> 00:02:52,640
常情况下形容词直接就放在名词的前面没有必要弄成
35
00:02:52,640 --> 00:02:56,940
一个定语重句放在后面因为弄成一个定语重句使句子
36
00:02:56,940 --> 00:02:58,540
变得复杂了这样就不好了
37
00:02:59,040 --> 00:03:03,180
但是这里呢它放在后面是有一个原因的因为它还要具
38
00:03:03,180 --> 00:03:07,700
体地说明这个 fast 到底有多大所以它放在后面这样就
39
00:03:07,700 --> 00:03:09,280
可以跟后面的这个数字
40
00:03:10,080 --> 00:03:12,380
很好的联系在一起 but
41
00:03:14,680 --> 00:03:19,680
possibly any size up to infinite 这个数字是至少这么
42
00:03:19,680 --> 00:03:20,920
大但
43
00:03:21,140 --> 00:03:25,640
其实我们并不清楚它到底有多大我们只知道它至少这
44
00:03:25,640 --> 00:03:26,100
么大
45
00:03:26,710 --> 00:03:32,430
那上限是多少呢不知道很可能是 any size up to
46
00:03:32,430 --> 00:03:36,230
infinite 很可能是无限大 and
47
00:03:36,580 --> 00:03:40,360
perfectly arrayed for the creation of stars,
48
00:03:40,640 --> 00:03:43,740
galaxies and other complex systems
49
00:03:44,380 --> 00:03:48,740
而且它还排列得非常整齐 arranged means
50
00:03:48,740 --> 00:03:55,540
arrangedarranged 这个词经常是指排兵布阵排兵布阵
51
00:03:55,540 --> 00:04:02,000
就是士兵把它排列得整整齐齐的所以 perfectly
52
00:04:02,000 --> 00:04:06,800
arranged 就是 perfectly arranged 整个是井然有序的
53
00:04:06,800 --> 00:04:10,490
一个宇宙就等待着恒
54
00:04:11,100 --> 00:04:18,050
星星系还有其他一些复杂系统的诞生 complex system
55
00:04:18,050 --> 00:04:21,130
complex 复杂的 Now
56
00:04:24,040 --> 00:04:27,180
let's look back on what we have covered today What
57
00:04:28,300 --> 00:04:29,400
caused the Big Bang?
58
00:04:29,660 --> 00:04:34,350
The scientists proposed many different notions Are
59
00:04:35,700 --> 00:04:39,900
we simply part of an eternal cycle of expanding and
60
00:04:39,900 --> 00:04:40,780
collapsing universes?
61
00:04:44,100 --> 00:04:48,980
introduced some degree of instability into the
62
00:04:48,980 --> 00:04:50,340
nothingness that was.
63
00:04:50,680 --> 00:04:54,960
Were big bans going on all the time everywhere?
64
00:04:56,820 --> 00:05:02,810
Was there space and time in other forms before the big
65
00:05:02,810 --> 00:05:03,090
ban?
66
00:05:04,730 --> 00:05:09,880
One scientist concluded that these are very close to
67
00:05:09,880 --> 00:05:10,800
religious questions.
68
00:05:12,760 --> 00:05:16,700
Well,then Alan Guth proposed inflation theory.
69
00:05:18,890 --> 00:05:23,070
The universe underwent a dramatic expansion shortly
70
00:05:23,070 --> 00:05:24,370
after the Big Bang.
71
00:05:25,030 --> 00:05:27,230
But what happened after the Big Bang?
72
00:05:28,140 --> 00:05:32,180
Well,a lot of things appeared in very short time.
73
00:05:33,140 --> 00:05:34,120
First the gravity,
74
00:05:34,280 --> 00:05:37,540
then electromagnetism and nuclear forces,
75
00:05:38,300 --> 00:05:40,140
then elementary particles,
76
00:05:40,420 --> 00:05:44,900
and the universe itself was doubling in size every 10 to
77
00:05:44,900 --> 00:05:52,300
the power of minus 34 seconds.Then we had a universe But
78
00:05:53,260 --> 00:05:58,450
then Here's another question But
79
00:05:59,000 --> 00:06:03,560
why is the universeturned out so well for us 我们
80
00:06:05,060 --> 00:06:09,340
的宇宙为什么就这么适合我们为什么就这么刚刚好呢
81
00:06:09,340 --> 00:06:10,340
You
82
00:06:12,070 --> 00:06:15,930
can find out about Goldilocks and the three bears You
83
00:06:15,930 --> 00:06:19,450
can find out about this storybefore our next section
84
00:06:19,450 --> 00:06:21,980
