Music Recording 16 Let's find out just how environmentally aware you are.

Question 1.
3
How many trees do you think it would take to offset the CO2 emissions from a long-distance flight?
4
Well, it's estimated that for each mile,
5
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 one and a half tonnes of CO2 per passenger.
8
The amount of CO2 a tree can absorb depends on factors such as its type,
9
location and age.
10
The company Future Forests says that on average it would take two trees 99 years to counter the effect of this trip.
11
So the answer here is C.
12
Question 2.
13
What is the most environmentally friendly way to wash your clothes?
14
Well, the solvents used by most dry cleaners are damaging to the environment.
15
In a washing machine, the vast majority of the energy,
16
about 90% of it, goes into heating up the water,
17
not running through the cycle.
18
Washing clothes in hot water,
19
even by hand, uses a lot of energy to heat the water.
20
Keeping washing temperatures low and always washing a full load is the best policy.
21
So the correct answer is C.
22
Question 3.
23
Do you need to always turn off your electric lights to save energy?
24
It is a common myth that flicking the lights on and off uses more energy than leaving them on.
25
In fact,
26
an ordinary bulb only has to be turned off for three seconds to outweigh the cost of turning it back on.
27
For energy efficient and other fluorescent bulbs,
28
this rises to five minutes.
29
Energy efficient light bulbs use 75% less energy than ordinary ones,
30
so if you have those but leave them on as you tidy,
31
you'll probably still use less energy than if you switch your standard bulbs on and off.
32
So the correct answer is B.
33
Question 4.
34
What is the most energy efficient way of cooking a baked potato?
35
A microwave uses just a third of the electricity required to operate an electric oven.
36
And, of course, the potato will take much less time to cook.
37
So the correct answer is B.
38
Question 5.
39
What is the best way to help reduce your CO2 emissions throughout the year?
40
Well, it's estimated that one person taking the train for a year,
41
rather than driving a car,
42
would reduce their CO2 emission total by 2.9 tonnes.
43
Hanging out your washing, rather than using a tumble dryer,
44
would cut CO2 by 0.9 tonnes,
45
and working from home one day a week would cut 0.88 tonnes.
46
So the correct answer is A.
47
Recording find out just how environmentally aware you are.

Question 1.

52
half a kilo of CO2 is added to the atmosphere.

このビデオで会話を練習する理由は？
このビデオを使用して会話を練習することは、英語のスピーキングスキルを向上させるために非常に効果的です。特にエネルギー危機や環境意識に関するトピックを扱うことで、参加者は現実の問題に対する理解を深めながら、関連する語彙を証明することができます。ビデオの内容は、日常会話で使える実用的な英語を提供し、学習者は内容に基づいて意見やアイデアを表現する練習ができます。このように、シャドースピーキングの技術を用いることで、より自然な発音と流暢さを身につけ、「英語の発音を良くする」ことができます。
文法と文脈における表現
このビデオでは、いくつかの重要な文法構造が使われています。以下にその例を挙げます：
- 「It's estimated that...」 - 予測や推測を表す構文で、データや情報を基にした意見を示す際に頻繁に使用されます。
- 「The amount of... depends on...」 - 何かの量が他の要因によって変わることを示す構文で、因果関係を強調できます。
- 「So the correct answer is...」 - 何かの選択肢に自信を持って結論づける際に使う表現です。
- 「...is the best policy」 - 最適な行動方針について話すときに役立つ表現で、提案をする際に用いられます。
これらの文法的表現を理解し、実際に使うことで、より高度な会話が可能になります。
一般的な発音の落とし穴
このビデオでは、いくつかの発音の難しい単語やフレーズが含まれています。例えば：
- 「environmentally」 - この単語は音節が多く、日本語話者には発音が難しいことがあります。クリアに発音するためには、各音の区切りを意識しましょう。
- 「energy efficient」 - これはスムーズに発音するための練習を必要とします。特に「efficient」の「sh」音に注意を払うと良いでしょう。
- 「CO2 emissions」 - CO2の部分は、省略することなくはっきり発音することが鍵です。
これらの単語をシャドーイングし、正しい発音を身に付けることで、英語シャドーイングのスキルを強化できます。
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。
