一、本课要点
- 过去完成时:公式:had + done。表示“过去的过去”,如Paul离开发生在Sarah到达之前。
二、核心词汇(5)
| 词条 | 释义 / 讲解 |
|---|
| Aim at | 对准,瞄准。文中指将望远镜对准天空。 |
| A touch of | 少许,几分。文中指说话时带着几分落寞的情绪。 |
| Beat them | 打败他们。beat在此处意为胜过、击败。 |
| Stellar | 星的,恒星的。词源来自拉丁文stella,区别于希腊词源的astro-。 |

三、句型与语法点(2)

|---|
| Go + V.原形 | 口语中go后直接接动词原形,如go wash your hands,表示去做某事。 |
| Had imagined | 过去完成时。表示在“过去某个时间点”之前已完成的心理活动,暗示该想法后来被修正。 |
四、课堂讨论题
1. 老师,讲稿里说 'go watch television' 这种 'go + 动词原形' 的用法挺常见的,除了这个,还有哪些类似的口语表达呀?
2. 文中提到 'a touch of dismay' 表示 '几分落寞',这里的 'a touch of' 具体是什么意思?它后面能接形容词吗?
3. 文中解释了 'stellar' 和 'astro-' 都表示星星,但词源不同。那 'astronomy'(天文学)里的 'astro' 是希腊语源,那 'stellar' 是拉丁语源对吗?
4. 为什么作者要用 'I had imagined'(过去完成时)而不是 'I imagined'(一般过去时)?这暗示了他现在的想法变了吗?
5. 文中用 'tipped from a giant can'(像大罐子打翻)来比喻星光流淌,这个比喻好生动。你能再举一个类似的、用日常物品比喻自然现象的例子吗?
五、Discussion Questions (English)
1. Teacher, the transcript mentions that 'go + verb' structures like 'go watch television' are common in spoken English. Besides this, what other similar colloquial expressions are there?
2. The text mentions 'a touch of dismay' meaning 'a bit of disappointment'. What exactly does 'a touch of' mean here? Can it be followed by an adjective?
3. The text explains that both 'stellar' and 'astro-' mean star but have different etymologies. So, 'astro' in 'astronomy' is Greek-derived, and 'stellar' is Latin-derived, right?
4. Why did the author use 'I had imagined' (past perfect) instead of 'I imagined' (simple past)? Does this imply that his current view has changed?
5. The text uses 'tipped from a giant can' (like a giant can tipping over) to metaphorically describe the flow of starlight. That's a vivid image. Can you give another example of a natural phenomenon described using a common household object?
六、听力 / 讲稿全文

00:00:06,100 --> 00:00:07,460
With CC Ds,
2
00:00:07,600 --> 00:00:11,240
you can aim a telescope at the sky and go watch
3
00:00:11,240 --> 00:00:11,660
television.
4
00:00:12,360 --> 00:00:16,840
Aim at 对准瞄准你
5
00:00:17,640 --> 00:00:22,720
现在有了这个工具的话你直接就把天文望远镜对着天
6
00:00:22,720 --> 00:00:26,860
空然后你就去看电视了就不用管它了 Go watch
7
00:00:26,860 --> 00:00:31,010
television 可能有的朋友会觉得奇怪为什么 go 后面可
8
00:00:31,010 --> 00:00:33,320
以直接跟上一个动词原型的
9
00:00:34,090 --> 00:00:39,030
其实这种情况还是常见的比如说 go wash your hand come
10
00:00:39,030 --> 00:00:45,530
have a look 如果经常看原版的小说的朋友不会
11
00:00:45,780 --> 00:00:51,440
感到陌生 Evans sat with a touch of dis maydismay means
12
00:00:51,440 --> 00:00:52,080
disappointment
13
00:00:52,700 --> 00:00:59,130
说话的时候还带着几分落寞 a touch of means a bit of he
14
00:00:59,520 --> 00:01:04,880
took all the romance out of it 也可以读作 romance it
15
00:01:04,880 --> 00:01:07,120
means the excitement of doing something
16
00:01:08,440 --> 00:01:15,100
这种神奇的激动的感受就全没了就是用上这种机器的
17
00:01:15,100 --> 00:01:17,420
话那就一点不好玩了
18
00:01:27,500 --> 00:01:35,180
受到什么诱惑我问他他是不是也想采用这种新技术呢
19
00:01:39,640 --> 00:01:40,560
Besides,
20
00:01:40,740 --> 00:01:44,300
he gave a nod at the photo of his latest supernova,
21
00:01:44,500 --> 00:01:47,420
and smiled.I can still beat them sometimes.
22
00:01:48,200 --> 00:01:50,380
有时候,我还比他们快呢。
23
00:01:50,440 --> 00:01:52,500
Be at them 是指打败他们。
24
00:01:52,760 --> 00:01:58,260
The question that naturally occurs is,
25
00:01:58,500 --> 00:02:01,800
what would it be like if a star exploded nearby?
26
00:02:02,360 --> 00:02:05,120
这就是我们上节课提出的问题。
27
00:02:15,550 --> 00:02:22,190
Stella 这个词是星星的意思这个是形容词
28
00:02:23,200 --> 00:02:29,090
它的词源来自拉丁文 Stella 意思就是 star 大家应该还
29
00:02:29,090 --> 00:02:36,740
有印象 astrologyastronomyastronautastronoma 这些
30
00:02:36,740 --> 00:02:41,560
词我们先前见过了我跟大家说过中间的这个 astro 是
31
00:02:41,560 --> 00:02:46,250
星星的意思那这里怎么又是一个也表示星星呢那是因
32
00:02:46,250 --> 00:02:51,040
为它们的词源不同 stellar 的词源来自拉丁文而 astro
33
00:02:51,040 --> 00:02:52,700
的词源是希腊文
34
00:02:54,390 --> 00:02:54,870
好
35
00:02:54,890 --> 00:02:58,330
大家再看一下 constellation 这个我们先前见过几次
36
00:02:58,330 --> 00:03:02,590
了就是星座这里边也有 Stella 我们
37
00:03:03,450 --> 00:03:09,590
现在的比较熟悉的词 Star 实际上也来自 Stella 好了
38
00:03:11,190 --> 00:03:17,110
离我们最近的邻居其实也就是指离我们最近的恒星了
39
00:03:17,110 --> 00:03:22,810
As we have seen It's Alpha Centaur i 就是先前说过的半
40
00:03:22,810 --> 00:03:26,520
人马座的 Alpha 星 It's 4.
41
00:03:26,920 --> 00:03:31,600
3 light years away I had imagined that if there were an
42
00:03:31,600 --> 00:03:32,000
explosion
43
00:03:45,070 --> 00:03:45,690
我
44
00:03:45,920 --> 00:03:52,007
设想我想象如果在那儿发生了一次爆炸的话那我们是
45
00:03:52,007 --> 00:03:53,440
不是就会有 4.
46
00:03:53,600 --> 00:04:01,540
3 年的时间来观看这个辉煌的事件发出的光 spreading
47
00:04:01,540 --> 00:04:05,080
across the sky 穿越太空朝
48
00:04:05,560 --> 00:04:07,040
我们流淌而来
49
00:04:07,200 --> 00:04:12,480
as if tipped from a giant cantipped means tilted 就是倾
50
00:04:12,480 --> 00:04:19,700
斜 giant can can 就是罐子就像是一个颜料罐被打翻了
51
00:04:19,700 --> 00:04:21,520
一样向我们流过来呢
52
00:04:22,360 --> 00:04:23,560
这个 can
53
00:04:23,740 --> 00:04:24,740
表示
54
00:04:24,800 --> 00:04:25,480
罐子
55
00:04:25,540 --> 00:04:29,440
罐头有一句罩口令 How
56
00:04:29,500 --> 00:04:34,580
many cans can a canner can if a canner can can cans 大家可
57
00:04:34,580 --> 00:04:36,940
以去练一练我们
58
00:04:37,520 --> 00:04:42,540
把刚才那句话简化一下只剩下主干就变成这样 I had
59
00:04:42,540 --> 00:04:46,980
imagined that we would have 4.3 years to watch the light
60
00:04:47,970 --> 00:04:55,990
这个时态 had 加上过去分词这是过去完成时过去完成
61
00:04:55,990 --> 00:04:59,090
时表示的是什么样的状况呢看这张图
62
00:04:59,730 --> 00:05:03,070
when she arrived at the party Paul had already
63
00:05:03,070 --> 00:05:09,120
leftarrived at the party 比如说这个诗意是 Sara when
64
00:05:09,120 --> 00:05:14,200
Sarah arrived at the party 她到达这个 party 肯定是发
65
00:05:14,200 --> 00:05:18,620
生在过去的事情这里用的是一般过去式那这个时候呢
66
00:05:18,620 --> 00:05:24,140
Paul had already left Paul 已经离开了那么 Paul 离开的
67
00:05:24,140 --> 00:05:24,440
时间
68
00:05:25,060 --> 00:05:33,180
一定是在 Sara 到达之前过去的过去在这种情况下我们
69
00:05:33,180 --> 00:05:35,400
就会用过去完成时
70
00:05:39,550 --> 00:05:41,650
那现在我们来看
71
00:05:45,870 --> 00:05:49,170
作者为什么要用 I had imagined
72
00:05:49,490 --> 00:05:56,510
而不是用 I have imagined 或者直接说 I imagined 用一般
73
00:05:56,510 --> 00:06:01,630
过去式呢 Hard to imagine 就表示在过去的某一个时间
74
00:06:01,630 --> 00:06:04,170
之前他是这样想的
75
00:06:04,770 --> 00:06:11,350
但是到了那个时间也就是刚才说的过去的那个时间到
76
00:06:11,380 --> 00:06:15,180
那个时间他就明白了自己这样想是错的
77
00:06:15,640 --> 00:06:19,580
所以他从那时起他就改变了自己的想法
78
00:06:20,080 --> 00:06:25,060
因此大家可以从他的说法从这个时态的用法看得出来
79
00:06:25,060 --> 00:06:27,520
他現在已經不這麼想了
