00:00:12,806 --> 00:00:15,405
Hello, everyone. I’m Venus Zhang.
大家好，我是Venus Zhang.

2
00:00:15,752 --> 00:00:21,426
Today I’m going to talk about how to make weather prediction in your future workplace.
今天我们将学习如何在你今后的职场中预测天气。

3
00:00:21,725 --> 00:00:31,200
As a student that just graduate from the college, you may have lots of chances to make a schedule or an appointment depending on the weather,
作为一名毕业生，你将有许多机会根据天气做日程计划或者安排预约，

4
00:00:31,228 --> 00:00:38,240
since outdoor activities will be greatly curtailed by heavy rain, snow and the wind chill. 
因为大雨、下雪或者风寒会大大影响你的计划安排。

5
00:00:38,243 --> 00:00:42,500
This case happens to Meryl too，who just got the message from the manager. 
Meryl也遇到这样的情形，经理发她信息，

6
00:00:43,513 --> 00:00:48,315
who asked her to make a weather prediction and schedule an outdoor exhibition. 
让她做一个天气预测，再安排室外展览日程。
 

7
00:00:49,637 --> 00:00:52,770
Here goes the message from the manager. 
经理发送给Meryl的信息如下：

8
00:00:55,348 --> 00:00:56,029
Hello! Mr. Cohen.
Cohen先生，您好！

9
00:00:56,348 --> 00:00:57,180
Have a seat, please.
请坐。

10
00:00:57,183 --> 00:01:00,593
Thank you, sir.
谢谢您。

11
00:01:00,795 --> 00:01:09,289
Our company will hold a three-day leisure products exhibition in Shanghai next month. 
我们公司下个月将在上海举办为期三天的休闲产品展览会。

12
00:01:09,324 --> 00:01:16,700
I know that  late spring is the rainy season, so I do not expect to hold the exhibition when it rains.
我知道春末通常也是雨季，但我不希望碰上雨天， 

13
00:01:16,935 --> 00:01:19,919
because this is an outdoor exhibition.
因为这次举办的是户外展览会。 

14
00:01:20,743 --> 00:01:31,129
So, Meryl, please check the weather forecast from March 10th to March 20th and give me advice on the best time to hold the exhibition.
Meryl, 请查询3月10日至20日的天气预报，并且就适合举办展览会的日期给我建议。

15
00:01:31,585 --> 00:01:33,670
Yes, sir. I’ll do my best.
好的，先生，我会尽力做好。

16
00:01:36,349 --> 00:01:39,501
But how can I make a weather forecast?
可是我该怎样做天气预报呢？

17
00:01:41,258 --> 00:01:51,700
All right, to help Meryl out, we need: first, know the vocabulary for describing weather, including adjectives, verbs and nouns; 
那么，为给Meryl解惑，我们首先应当了解描述天气所需的形容词、动词及名词等。

18
00:01:51,768 --> 00:01:55,615
next, the modals verbs for talking about possibility, 
接下来，我们要学习预测天气所需的情态动词，

19
00:01:55,775 --> 00:02:00,624
and finally, several sentences for predicting weather. 
最后学习预测天气的句型。

20
00:02:01,388 --> 00:02:04,734
Let’s talk about the vocabulary first. 
我们先来学习词汇。

21
00:02:04,746 --> 00:02:13,350
When describing the weather conditions, we usually observe the sun, cloud, and some phenomenon of the earth. 
在描述天气时，我们常观察太阳、云朵等一些天气现象。

22
00:02:13,502 --> 00:02:15,880
So we can use “snowy”; 
因此我们可以用的词汇包括“下雪的”：

23
00:02:17,555 --> 00:02:25,132
“stormy”, which is to describe the violent rain with strong wind and often thunder and lightning; 
“暴风雨的”是用来描述伴有强风，时常有雷电、强降雨的天气；

24
00:02:25,484 --> 00:02:27,700
“rainy”; 
“下雨的”；

25
00:02:27,806 --> 00:02:29,050
“windy”;
“刮风的”；

26
00:02:29,140 --> 00:02:34,300
“breezy”, which is to describe the light or gentle wind;  
“有微风的”用来描述较弱的微风；
 

27
00:02:34,589 --> 00:02:39,150
“foggy”, a state of mass of droplets of water vapor; 
“雾深的”用来描述凝结成细微水滴悬浮于空中的水汽;

28
00:02:39,349 --> 00:02:43,678
and “sunny”, which is the favorite of all of us.
以及“和煦的”，阳光明媚的天气可是我们大家都喜爱的。

29
00:02:44,474 --> 00:02:55,450
Besides the adjectives for describing what the weather’s like, we also need to describ our feelings about how hot or how cold it is.
除了描述天气，我们还需要描述对温度的感知。
 

30
00:02:55,495 --> 00:02:58,846
Then, comes the temperature. 
因此，接下来我们谈谈温度。

31
00:02:58,900 --> 00:03:07,600
Here, we can use words like “frozen”, “cold”, “chilly”, “cool”, “warm”, “hot” and “scorching”
我们用诸如“冰冷的”、“寒冷的”、“冷飕飕的”、“凉爽的”、“温暖的”、“炎热的”、
“酷热的”等词汇来表达我们对冷热的感知。

32
00:03:07,691 --> 00:03:12,808
These words are listed as the degree of heat that our body may feel. 
以上几个词是按照我们人体对外界温度感知的从低到高排序的。

33
00:03:14,280 --> 00:03:24,092
Then, to express the amount of water vapor, we can use words like “dry”, “wet”, “humid”, etc. 
另外，如要表达空气中的水汽含量的不同程度，我们可以用“干燥的”、“潮湿的”、“湿润的”等等。

34
00:03:25,741 --> 00:03:35,606
As for verbs about weather, besides "snow" and "rain",we could use “hail”, the small balls of ice or sometimes snow, 
而动词方面，我们有“下冰雹”，一种小冰粒或小雪球，

35
00:03:35,967 --> 00:03:43,500
and “sleet”, the frozen rain or mixture of rain and snow or hail.
以及“雨夹雪”或“冻雨”，

36
00:03:43,805 --> 00:03:56,000
In addition to “storm”, which is what we explained just now, we can also use some nouns like “tornado”, “hurricane”, and “typhoon”.
除了“暴风雨”可以作为名词，还需学习一些名词如“龙卷风”，“飓风”以及“台风”。

37
00:03:56,011 --> 00:03:59,870
All these three are severe and powerful storm. 
以上三种风都是强风。

38
00:04:01,647 --> 00:04:10,342
Having learnt the vocabulary, you may wonder “how should I predict the possibility of weather while it is so changeable?”
在学习了词汇之后，你可能会好奇天气如此多变，我如何才能预测天气的可能性呢？

39
00:04:10,253 --> 00:04:15,665
Well, let’s move to modals for talking about possibility. 
那么，我们接下来谈谈如何应用情态动词来表达可能性。

40
00:04:16,191 --> 00:04:27,674
The range of intensity or degrees, from the weakest to strongest is as follows: might, could, should, must, and will. 
情态动词在表示可能性时由弱至强的排序是“might, could, should, must, will”。

41
00:04:28,377 --> 00:04:35,290
“Might” shows the weakest possibility, which is of only 10% or less chance. 
“Might”表示只有10%的可能，其可能性最弱。

42
00:04:34,562 --> 00:04:40,500
For instance, if your friend is jogging on a hot summer evening but it’s a little cloudy,
例如，假如你的朋友要在稍微多云的夏日傍晚慢跑，

43
00:04:40,901 --> 00:04:48,042
you can give your friend suggestion like “It might be cool and you could wear a sweater.”
你可以给出这样的建议：“气温可能稍凉，把运动衫穿上吧。”

44
00:04:48,917 --> 00:04:54,899
“Could” is used to express 20% of certainty.
“Could”表示有20%的可能性。

45
00:04:55,981 --> 00:05:01,333
So if you want to give advice to whom try to do outdoor exercise on a snowy day, 
因此如果要给在下雪天做户外运动的他人提建议时，

46
00:05:00,763 --> 00:05:06,458
you should say “It could snow and you should practice inside.”
应当说“可能会下雪，你应该在室内做运动。”

47
00:05:07,216 --> 00:05:12,418
Then, to offer suggestion for someone who’s going to go outside when it’s quite cloudy,
在给大阴天出门的人建议时，

48
00:05:13,941 --> 00:05:17,500
you could say “It's going to rain and you should take an umbrella.” 
你可以说“要下雨了，你应该带把伞”；

49
00:05:17,787 --> 00:05:21,982
because “should” is of 50% certainty.
这里“should”表示有50%的可能性。

50
00:05:22,984 --> 00:05:28,674
When you are 90% sure about something, you could use “must”. 
如果对某事有90%的把握性，你可以用“must”。

51
00:05:27,992 --> 00:05:34,929
For instance, “There is a great chance of rainy weather and it must rain and remain cold.” 
举个例子，“下雨的可能性很大，这天天气很可能下雨而且会一直很冷。”

52
00:05:35,733 --> 00:05:41,597
To express 100% certainty, you should use modal verb “will”. 
在表示100%可能性时，可以用“will”。

53
00:05:41,700 --> 00:05:51,078
For instance, on a cold winter day, you could predict “Temperatures will drop to below -5 degrees and it could snow today.”
例如，如果冬天的某天很冷，你可以预测说“由于温度要降到零下五度了，今天有可能会下雪”。

54
00:05:52,978 --> 00:05:59,145
The third step to make prediction about weather needs our application of certain sentence patterns. 
第三步我们学习预测天气的句式。

55
00:05:59,394 --> 00:06:04,287
Here, we offer you a map to do a simulation of weather forecast. 
这里有一副天气预报的地图供大家做模拟演练。

56
00:06:04,472 --> 00:06:07,000
What can you tell from the weather map? 
根据地图，你可以说些什么呢？

57
00:06:07,048 --> 00:06:14,179
Look, with useful expressions given, please try to give a weather forecast by using sentences such as
根据给出的短语提示，请试试用这些句子来预测天气，

58
00:06:14,439 --> 00:06:26,659
“It could be warm in Salt Lake City, because according to the map Area One is sunny and there is only 20% chance of rain;”
“根据地图，区域一阳光明媚，只有20%的可能性下雨，因此盐城可能天气怡人。”

59
00:06:26,736 --> 00:06:37,324
“It should be very cold in Houston because the map shows Area Three has 50% chance of sleet and ice.”
“地图显示，区域三有50%雨夹雪并结冰的概率，因此休斯顿应该会很冷。”

60
00:06:37,683 --> 00:06:42,100
With the vocabulary, modal verbs and sentence patterns that are mentioned above, 
学习了以上所讲的词汇、情态动词及句型，

61
00:06:42,156 --> 00:06:51,321
we can now use weather forecasts to determine what to wear on a given day, and how to make appointments and schedule activities.
现在我们可以利用天气预报得知某一天如何穿衣，如何计划日程和安排预约了。

62
00:06:51,491 --> 00:06:57,100
Planning ahead based on weather prediction and forecasts will help survive them. 
提前预测天气可以避免这些活动受到天气影响。

63
00:06:57,231 --> 00:07:05,500
But here, you may also want to know, what if we need to give a suggestion by using the negative forms of modal verbs? 
但是你可能还会提出疑问，如果要通过情态动词的否定形式来预测天气，该如何做呢？

64
00:07:05,947 --> 00:07:12,000
For instance, when it is both sunny and cloudy, what should we say about the weather? 
例如，如果天气晴间多云，我们应该怎么说呢？

65
00:07:12,114 --> 00:07:19,100
Well here, we can form negative statements such as ‘there isn’t a great chance of rain”, 
这里，我们可以说“下雨的可能性不大”，

66
00:07:19,265 --> 00:07:29,500
“it is not very likely to rain”, or “it will not rain” to predict the impossibility of weather.
 “不大可能下雨”，或者“不会下雨”。

67
00:07:29,613 --> 00:07:36,300
By searching on the Internet, Meryl now has got the weather forecasts from March 10th to March 20th, 
通过上网，Meryl已经查询到3月10日到20日的天气预报。

68
00:07:36,613 --> 00:07:47,200
and she can make a weather report with the vocabulary, modal verbs and sentence patterns that we just learnt. Here goes the report she is preparing. 
她会用我们刚才所学到的词汇、情态动词及句型做一个天气汇报。请看：

69
00:07:47,427 --> 00:07:59,000
Look, she just got the message from the manager, and tomorrow she has to meet him and give him the report she prepares.
现在，Meryl刚收到经理发来的信息，明天她将去见经理并提交准备好的报告。

70
00:07:59,194 --> 00:08:00,190

71
00:08:00,195 --> 00:08:01,900

00:08:01,978 --> 00:08:04,900
Thank you.

73
00:08:04,910 --> 00:08:11,910
I have checked the weather prediction online,  and I‘ve prepared this for you. May I talk about it now? 
我在网上查阅了天气预报，并且准备了这个报告。我现在可以告诉您有关的天气情况吗？ 

74
00:08:11,954 --> 00:08:14,500
Yes, please. 
好的，请说。

75
00:08:14,662 --> 00:08:23,000
Well, there is a 30% chance of rain on the 10th and an 80% percent chance of rain the next day. 
3月10有30%的可能性会下雨，而11日有80%的可能性下雨。

76
00:08:23,012 --> 00:08:29,600
It will rain all day on the 12th and 13th and the temperature is going to drop to 16 degrees.    
12日和13日全天都会下雨，温度也将下降至16度。 
   

77
00:08:29,818 --> 00:08:35,200
There could be sun with light showers on the 14th and 15th, 
14日和15日可能会转晴并且伴有小的阵雨，

78
00:08:35,281 --> 00:08:41,300
but there is a good chance of nice weather starting on the 16th through the weekend. 
但从16日至周末很有可能是好天气。     

79
00:08:41,406 --> 00:08:47,000
There will be a mix of sun and clouds on these days but it will not rain. 
这几天天气将是晴间多云，但肯定不会下雨。    

80
00:08:47,085 --> 00:08:54,700
So I think it may be better if the exhibition is held from the 16th to 20th. 
所以我认为16日至20日之间举办展览会比较合适。

81
00:08:54,862 --> 00:08:59,700
I’ve written a brief weather prediction for Shanghai. Here you are. 
我做了一个简短的上海天气预报给您。

82
