1
Recording 16.
2
Let's find out just how environmentally aware you are.
3
Question 1.
4
How many trees do you think it would take to offset the CO2 emissions from a long-distance flight?
5
Well, it's estimated that for each mile, or 1.6 kilometres, that a jet flies,
6
half a kilo of CO2 is added to the atmosphere.
7
So, a round trip of 10,000 miles would emit about 1.5 tonnes of CO2 per passenger.
8
The amount of CO2 a tree can absorb depends on factors such as its type, location and age.
9
The company Future Forests says that on average it would take two trees 99 years to counter the effect of this trip.
10
So, the answer here is C.
11
Question 2.
12
What is the most environmentally friendly way to wash your clothes?
13
Well, the solvents used by most dry cleaners are damaging to the environment.
14
In a washing machine, the vast majority of the energy, about 90% of it, goes into heating up the water, not running through the cycle.
15
Washing clothes in hot water, even by hand, uses a lot of energy to heat the water.
16
Keeping washing temperatures low and always washing a full load is the best policy.
17
So the correct answer is C.
18
Question 3.
19
Do you need to always turn off your electric lights to save energy?
20
It is a common myth that flicking the lights on and off uses more energy than leaving them on. In fact,
21
an ordinary bulb only has to be turned off for three seconds to outweigh the cost of turning it back on.
22
For energy efficient and other fluorescent bulbs, this rises to five minutes.
23
Energy-efficient light bulbs use 75% less energy than ordinary ones.
24
So if you have those, but leave them on as you tidy, you'll probably still use less energy than if you switch your standard bulbs on and off.
25
So the correct answer is B.
26
Question 4.
27
What is the most energy-efficient way of cooking a baked potato?
28
A microwave uses just a third of the electricity required to operate an electric oven.
29
And, of course, the potato will take much less time to cook.
30
So the correct answer is B.
31
Question 5.
32
What is the best way to help reduce your CO2 emissions throughout the year?
33
Well, it's estimated that one person taking the train for a year,
34
rather than driving a car would reduce their CO2 emission total by 2.9 tonnes.
35
Hanging out your washing rather than using a tumble dryer would cut CO2 by 0.9 tonnes
36
and working from home one day a week would cut 0.88 tonnes.
37
So the correct answer is A.

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。
