Test practice track 5.

You will hear a university lecturer and a student discussing genetically modified crops.

First you will have some time to look at questions 1 to 7.

Now listen carefully and answer questions 1 to 7.

Hi, Dr Finn.

Hi, John.

Did you manage to read that article I sent you to help with your dissertation on genetically modified crops?

Yes, thanks very much.

I've just read it.

Some of the research results were pretty incredible.

They've made some amazing advances, haven't they?

Like the research on the maize crop they mentioned.

Yeah, that's the one that was described as being wildlife friendly, wasn't it?

Yes, it's good to see a GM crop that won't have a detrimental effect on nearby livestock.

And it's nice to see there's less focus generally on increasing profits above all else.

True.

I thought the research on the soya bean crop was really promising as well.

Apparently it's designed to be resistant to weeds, so farmers don't need to rely on chemicals to remove them.

And that'll lower the risks for growers too, then.

And if they could manage to do something similar with a crop like wheat, that'd drive down the cost of food and improve the quality of the water supply as well.

Yes, I like that it's not just pests and things that the new GM crops can guard against.

I was interested to read about the plans for a new potato crop.

Hmm.

It's said they're aiming to introduce an antifreeze that's found naturally in fish into the potato crops, so they can withstand extreme temperatures.

That would be a huge advantage for remote areas that struggle through harsh winter conditions.

I agree.

Another crop I've read about that could help people in poorer areas is a new variety of rice.

It's such a staple food in many areas, and the plan is to create a crop that contains a richer supply of nutrients.

Yes, I've read about that.

They're trying to produce rice that'll supply high levels of vitamin A in particular, aren't they?

Yes, but in my dissertation I'd also like to show that GM crops can have uses beyond just supplying food.

Well, did you read about the planned use for tomato plants?

Yes, that's amazing.

They plan to use tomatoes to transport medicines, don't they?

Yes, that's right.

Transporting vaccines isn't easy because they're so fragile.

So they're hoping to make an edible vaccine using tomatoes, one that'll be easier to ship, store and even administer.

It's a really good example of the varied uses GM crops can have.

Exactly.

And I'm hoping to include a section on the work that's being done on trees, poplar trees in particular.

The aim is to create a tree that can soak up contaminants, like heavy metals, right out of the soil.

It's an incredible idea, isn't it?

A tree like that could potentially eradicate many of our current environmental issues.

Yes, the work they're doing should really persuade people just how good this type of biotechnology can be.

Before you hear the rest of the conversation, you will have some time to look at questions 8 to 10.

Now listen carefully and answer questions 8 to 10.

I think articles like that can be very useful, don't you?

I agree.

It's important to reach out to the general public and show that biotechnology shouldn't be feared.

Yes, and the writer certainly covered a lot of the new food crops under development.

It's good to have the very latest information.

Things have clearly changed a great deal over the last few years.

That's right.

It could have been a bit more balanced in its approach, though, don't you think?

I suppose so.

There was really only one side presented.

People do need to have all of the facts, and this article didn't really do that, did it?

No. I suppose the aim was to provide a convincing argument for GM crops.

And what did you think about the proposed change to regulations?

Well, the writer was certainly very enthusiastic about it, but I have to say what they're suggesting sounds pretty alarming to me.

I'd have to agree with you there.

The plan is to give farmers more control

so they get to decide whether testing of any of their new GM crops is needed

and I'm struggling to see why they would want to do that.

I agree.

It's bound to make the public feel even more uneasy than they are at present.

It's certainly not going to win over anyone who already has their doubts about GM crops.

And I do think the public has a right to know about potential problems.

Even many scientists still have concerns.

Yes.

I used to think the only real concern was that these crops could spread uncontrollably and affect natural crops.

But that's not the case, is it?

That's certainly one issue.

But when it comes to getting consumer support, it's far more worrying that we still can't completely rule out possible allergic reactions to these foods.

I guess that's something that definitely needs to be researched thoroughly, and the public would need to feel reassured about.

Yes.

Tests they've done so far on chickens and pigs have shown that, at the moment, we can't really predict what impact these foods will have in the long term.

It seems like there's a long way to go yet.

この動画で身につけるスキル

大学講師と学生の対話を通じて、英語スピーキング練習に必要な実践的なスキルが身につきます。まず、専門用語（遺伝子組み換え作物やバイオテクノロジー関連の単語）を自然に会話に組み込む方法を学びます。次に、意見を述べる際の流れ（「Yes, thanks very much. I've just read it.」のような応答から具体的な感想を述べる展開）を理解し、スムーズな会話のリズムを掴むことができます。さらに、相手の発言に対して適切に同意や追加情報を提供する（「True. I thought...」「Yes, I like that...」）コミュニケーションスキルも養います。

聞き取りに注意すべき発音のポイント

この対話には多くの連結発音や弱められた発音が含まれています。例えば、「Did you manage to read that」は「Didja manage to read that」のように連結され、「you」が「ja」に弱められます。また、「they've made some amazing advances」では「they've」が「theyv」となり、「some」が「səm」と弱く発音されます。「I've just read it」の「I've」も「Iv」と短くなります。これらの発音を聞き取ることで、実際の会話に慣れ、英語の発音を良くする基礎ができます。

ネイティブのように話すコツ

英語シャドーイング（shadow speak）を行う際は、リズムとストレスを真似ることが重要です。この対話では、キーワード（「incredible」「promising」「antifreeze」など）が強調され、その前後の単語は軽く流れます。例えば、「Some of the research results were pretty incredible」では「incredible」にストレスが置かれ、「pretty」は弱められます。また、疑問文のイントネーション（「They've made some amazing advances, haven't they?」の上昇調）も真似ることで、自然な発音に近づきます。shadowspeakの練習でこれらのポイントを繰り返し磨くことで、ネイティブ並みの流暢さが得られます。

この動画の文法

話し手がよく使っている文型を、動画の実際の表現とともに紹介します。

文型	動画での表現
現在完了形 have/has + 過去分詞 — 過去の出来事が今も関係している	I've just read · They've made · I've read
受動態 be + 過去分詞 — 誰がするかより、何が起きるかに焦点を当てる	was described · being done · be feared

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。
