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.

這個影片適合誰？

如果你正在準備英語聽力考試，尤其是涉及學術討論的題型，或者想通過影子跟讀（英語影子跟讀）提升聽說能力，這個影片再合適不過。它模擬了大學講師與學生的對話場景，話題圍繞轉基因作物，內容兼具專業性與實用性，適合有一定基礎、希望突破聽力理解和口語表達的學習者。

值得借鑑的詞彙與表達

detrimental effect：有害影響。例：這種轉基因作物不會對附近牲畜產生有害影響。
staple food：主食。例：大米是許多地區的主食。
soak up contaminants：吸收汙染物。例：楊樹能從土壤中吸收重金屬等汙染物。
administer：施用（藥物）。例：可食用疫苗更易運輸、儲存和施用。

這些表達在學術討論和日常交流中都很常用，記住它們能讓你的英語更地道。

如何練好發音？

影片中說話者的發音清晰，語速適中，非常適合影子跟讀練習（shadow speech）。注意以下幾點：一是連讀，比如“aiming to”讀作/ˈeɪmɪŋ tə/，“soak up”讀作/səʊk ʌp/；二是重音，如“genetically modified”中“genetically”的重音在第三音節，“modified”在第一音節；三是語調，疑問句和陳述句的語調變化要自然。你可以反覆播放影片，跟著模仿（shadowspeaks），逐漸跟上節奏。堅持使用這樣的影子跟讀網站（shadowing site）練習，能有效提高英語發音和聽力理解能力。

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事	I've just read · They've made · I've read
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	was described · being done · be feared

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
