VT29: How do Birds Navigate? 鳥怎麼都不會迷路啊?

Vocabulary Challenge 29: https://tw.voicetube.com/everyday/20190911

Script:

How do birds know where they’re going all the time?

鳥類如何知道它們一直在哪裡?他們使用Google地圖還是蘋果地圖?當他們沒有WIFI時會發生什麼?

Do they use Google maps or maybe Apple maps?

他們使用Google地圖還是蘋果地圖?當他們沒有WIFI時會發生什麼?

What happens when they don’t have WIFI?

Seriously, how do birds know where they are going when I can’t even get to a new grocery store without my phone.

Most of us will probably guess they use the Earth’s magnetic field to guide them or something but is this really the case?

說真的,如果沒有GPS,鳥怎麼知道他們要去哪裡?

What words come to your mind when you think of birds and directions? Navigation? Magnetic field? 真是有夠鳥?

Let’s move on to our sentence of the day.


Unfamiliar constellations were useless to the birds, which means that they learn constellations as they migrate and use them to navigate on future migrations.

不熟悉的星座對鳥類而言是毫無用處的,這意味著牠們一面遷徙,一面在認識星座,未來的遷徙就可以利用星座來導航。


So let’s say this sentence again.

Unfamiliar constellations were useless to the birds, which means that they learn constellations as they migrate and use them to navigate on future migrations.

Faster

Unfamiliar constellations were useless to the birds, which means that they learn constellations as they migrate and use them to navigate on future migrations.


OK, you know this game. What are the possible thought groups? 「字組」

Unfamiliar constellations were useless to the birds, (1)

which means that they learn constellations as they migrate (2)

and use them to navigate on future migrations. (3)

So I broke it to three clauses this time. While we can have more pauses, this would make sure each idea is fluently presented.


How about intonation? 語調

Unfamiliar constellations were useless to the birds, (fall-idea is complete)
which means that they learn constellations as they migrate (rise, more info).

and use them to navigate on future migrations(fall).

The nonrestrictive adjective clause/relative clause is used to provide more information.


What about the sentence stress? 句子的重音 You could say:

Unfamiliar constellations were useless to the birds,

which means that they learn constellations as they migrate

and use them to navigate on future migrations.

Only the speaker of an utterance knows which words are important to him/her.

Where did he hide the document?

Where – the location is the key here
he – He, not anyone else, is the focus
hide – hide, not write or read
the – The significant or important document
document – the document not anything else


OK, it’s grammar time!!! 大家最愛的文法時間到了!!!

Today’s sentence pattern is

Unfamiliar constellations were useless to the birds,

which means that they learn constellations as they migrate  

and use them to navigate on future migrations.

What exactly is which? We know that “which” is a nonrestrictive relative pronoun, but what is it? Constellations? Birds?

“Which” in this case represent the aforementioned concept. So, in this sentence, WHICH means “Unfamiliar constellations were useless to the birds”

It is used to represent the ENTIRE concept. Some people think this is not a precise way to write. Because WHICH might not be clear when you read. However, “which means…” is used all the time in speech to give an explanation.

which means…

What this means is that…


OK, let’s take a break.

Have you watched the video yet? I found this part to be the most important:

Star compass. Not only do birds use obvious information like the sun, they are able to use the position of stars to navigate

We’re not sure exactly how birds sense the Earth’s  magnetic field at this time. Birds can use rivers, mountains, and forests to find their way along a migration route. Some birds appear to use smell landmarks, sniffing their way across a map of familiar smells.

我們目前還不確定鳥類究竟是如何感知地球的磁場的。有證據支持這種感官器官位於牠們的喙,耳朵或眼睛。地標很重要。鳥類善用河流,山脈和森林沿著遷徙路線前進。有些鳥似乎使能用「嗅覺地標」,在熟悉的「氣味地圖」上嗅探。

What?! I can’t believe birds could do these things?

That’s amazing info but what can we do with it? Many learners focus on acquiring information but they don’t think about how to use the knowledge they gain.

Is it possible for us to use these mechanisms to produce better maps? Maybe even in outer space where the magnetic field is different? Or, should we just rely on satellites? These are all possibilities you should think about. When you learn anything, think about how it relates to you, and how you can use this information to make a difference.


OK, let’s go back to vocabulary learning and go over some new words.
