1
You will hear part of a lecture about the study on Australian crocodiles.
2
First, You have some time to look at questions 31. to 40.
3
Now listen carefully and answer questions 31 .0 to 40.
4
Around 10 years ago, Australia Zoo, the University of Queensland and Queensland Parks and Wildlife,
5
undertook a project to monitor the movements and behavior of the crocodiles in Lakefield National Park.
6
The aim of the study was to provide better information on how adult crocodiles there Interact within a river system.
7
enabling people to have better decisions on how to manage crocodile populations.
8
This project can lead the world in crocodile management, Because of the use of satellite.
9
which enables scientists to stably receive accurate information being sent back to them on the computer.
10
Even though the crocodiles can travel very long distances, scientists can still know where they are and study their habits.
11
The study is going to help scientists gain further knowledge
12
on crocodile behaviour which can help make informed decisions on the management plans for crocodiles,
13
not only in Australia, but around the world.
14
Crocodile tracking isn't a new idea in Australia.
15
Crocodile studies have been previously conducted by radio.
16
A miniature electronic device was implanted under the skin of these animals, and they were released back into the river.
17
These tags enabled scientists to track the movements of these particular crocodiles over the next 10 years. Of course.
18
There are some unexpected challenges.
19
The data transmitted from each receiver is recorded by some devices employed in the receiving stations.
20
However, Some devices, are too old.
21
that they always lose signals due to a variety of reasons.
22
so they can't track those animals which they have been studying for months.
23
In order to study the crocodiles, They must first be captured.
24
so that the device can be put on them.
25
But this is a very difficult task.
26
because they are alert and afraid of being followed by humans.
27
so it might take the team several hours to capture one.
28
The tracking device has signal transmitters inside and it's waterproof.
29
It is attached to the head of the crocodile.
30
so the crocodile cannot remove the device with its feet or tail.
31
The research has begun to reveal the movements of crocodiles.
32
Data showed that crocodiles tend to be more active at night time.
33
The GPS sometimes shows that in some areas the crocodiles are overpopulated.
34
So scientists at the park have to use a helicopter to
35
relocate the crocodiles in order to control their population in the area.
36
A crocodile would be taken many kilometers away from its original place.
37
However, Scientists found that the relocation methods were ineffective.
38
because the relocated crocodiles will return to their original location following the most direct route within one week.
39
The tracking data shows that the crocodiles swim right back to where they came from when moved.
40
Crocodiles sometimes travel hundreds of kilometers from Indonesia to Australia in order to reproduce.
41
It is interesting to see that they can always find their way and they will not get lost in the ocean.
42
Scientists realized The crocodiles are able to navigate.
43
This is an important ability for them when they have to migrate for very long distances.
44
We may wonder if human beings can learn from the crocodiles and find our way without using technology.
45
However, through lots of research and experiments, Scientists conclude, that crocodiles can tell directions by using their senses to the sun.
46
so that they know where they're going.
47
This is an ability which human beings don't possess.
48
Another finding is that like the migration of birds who can travel thousands and thousands of kilometers, Crocodiles have the same system to help them travel.
49
The research is still going on in Northern Australia.
50
Scientists are working hard to gather more information about this amazing creature.
51
That is the end of section 4.
52
You now have half a minute to check your answers.
53
That is the end of the listening test.
54
In the IELTS test, you would now have 10 minutes to transfer your answers to your answer sheet.

この動画がスピーキング練習に最適な理由

YouTubeで英語学習をするなら、オーストラリアのワニ研究についてのこの講義動画は見逃せません。IELTS スピーキング対策にも役立つ、自然なスピーチのリズムや専門用語が豊富で、shadow speak(シャドーイング)の練習にぴったりです。話者の語調やポーズがリアルで、日常的な会話だけでなく、説明的な文章のスピーキングも磨けます。

自然な表現を分解してみよう

  • "The aim of the study was to provide better information on how adult crocodiles interact within a river system." 「研究の目的は、成体ワニが河川系内でどのように相互作用するかについて、より良い情報を提供することでした」。"interact within a river system" のように、具体的な場面での動詞の使い方が自然で、IELTSの説明問題でも活かせます。
  • "However, the relocated crocodiles will return to their original location following the most direct route within one week." 「しかし、移動させられたワニは1週間以内に最も直接的なルートをたどって元の場所に戻ります」。"relocated" や "most direct route" などの単語の組み合わせがスムーズで、発音のリズムを練習するのに適しています。
  • "Crocodiles can tell directions by using their senses to the sun." 「ワニは太陽に対する感覚を使って方向を知ることができます」。"tell directions" や "using their senses to the sun" の表現が斬新で、英語の発音を良くするための繰り返し練習に最適です。

効果的な練習ルーティン:shadow speak

まず動画を1回聴いて全体の流れを把握し、次に1文ずつ止めながらshadow speakを行います。「ワニの追跡方法」や「移動の理由」などのキーワードを覚えながら、話者の発音やイントネーションを真似ましょう。録音機能を使って自分の声を録り、元の動画と比較することで、発音の癖やリズムの違いに気づけます。1日10分、1週間続けると、英語のスピーキング力が飛躍的に向上します。これがYouTubeで英語学習する際の最強の方法です!

シャドーイングとは?英語上達に効果的な理由

シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
