1
Section 4.
2
You will hear a university lecture about an endangered bear in British Columbia, Canada, known as the Spirit Bear.
3
First, you have some time to look at questions 31 to 40.
4
Thank you.
5
Now listen carefully and answer questions 31 to 40.
6
series on ecology and conservation with a look at a particularly endangered member of the black bear family.
7
One in ten black bears is actually born with a white coat,
8
which is the result of a special gene that surfaces in a few.
9
Local people have named it the spirit bear, and according to the legends of these communities,
10
its snowy fur brings with it a special power.
11
Because of this, it has always been highly regarded by them,
12
so much that they do not speak of seeing it to anyone else.
13
It is their way of protecting it when strangers visit the area.
14
The white bear's habitat is quite interesting.
15
The bear's strong relationship with the old growth rainforest is a complex one.
16
The white bear relies on the huge, centuries-old trees in the forest in many ways.
17
For example, the old-growth trees have extremely long roots
18
that help prevent erosion of the soil along the banks of the many fish streams.
19
Keeping these banks intact is important because these streams are home to salmon, which are the bear's main food source.
20
In return, the bear's feeding habits nurture the forest.
21
As the bears eat the salmon, they discard the skin and bones in great amounts on the forest floor, which provide vital nutrients.
22
These produce lush vegetation that sustains thousands of other types of life forms, from birds to insects and more.
23
Today, the spirit bear lives off the coast of the province of British Columbia on a few islands.
24
There is great concern for their survival, since it is estimated that less than 200 of these white bears remain.
25
The best way to protect them is to make every effort to preserve the delicate balance of their forest environment,
26
in other words, their ecosystem.
27
The greatest threat to the bear's existence is the loss of its habitat.
28
Over many years, logging companies have stripped the land by cutting down a large number of trees.
29
In addition, they have built roads which have fractured the areas where the bear usually feeds,
30
and many hibernation sites have also been lost.
31
The logging of the trees along the streams has damaged the places where the bears fish.
32
To make matters worse, the number of salmon in those streams is declining, because there is no legal limit on fishing at the moment.
33
All these influences have a negative impact on the spirit bear's very existence,
34
which is made all the more fragile by the fact that reproduction among these bears has always been disappointingly low.
35
And so, what's the situation going forward?
36
Community organizations, environmental groups, and the British Columbia government are now working together on the problem.
37
The government is now requiring logging companies to adopt a better logging method, which is a positive step.
38
However, these measures alone may not be sufficient to ensure a healthy population of the spirit bear in the future.
39
Other steps also need to be taken.
40
While it is important to maintain the spirit bear's habitat, there also needs to be more emphasis on its expansion.
41
The move is justified, as it will also create space for other bears that are losing their homes to...
42
That is the end of Section 4.
43
You now have half a minute to check your answers.
44
Thank you.
45
IELTS test, you would now have 10 minutes to transfer your answers to the answer sheet.

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。
