1
Test practice track 5.
2
You will hear a university lecturer and a student discussing genetically modified crops.
3
First you will have some time to look at questions 1 to 7.
4
Now listen carefully and answer questions 1 to 7.
5
Hi, Dr Finn.
6
Hi, John.
7
Did you manage to read that article I sent you to help with your dissertation on genetically modified crops?
8
Yes, thanks very much.
9
I've just read it.
10
Some of the research results were pretty incredible.
11
They've made some amazing advances, haven't they?
12
Like the research on the maize crop they mentioned.
13
Yeah, that's the one that was described as being wildlife friendly, wasn't it?
14
Yes, it's good to see a GM crop that won't have a detrimental effect on nearby livestock.
15
And it's nice to see there's less focus generally on increasing profits above all else.
16
True.
17
I thought the research on the soya bean crop was really promising as well.
18
Apparently it's designed to be resistant to weeds, so farmers don't need to rely on chemicals to remove them.
19
And that'll lower the risks for growers too, then.
20
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.
21
Yes, I like that it's not just pests and things that the new GM crops can guard against.
22
I was interested to read about the plans for a new potato crop.
23
Hmm.
24
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.
25
That would be a huge advantage for remote areas that struggle through harsh winter conditions.
26
I agree.
27
Another crop I've read about that could help people in poorer areas is a new variety of rice.
28
It's such a staple food in many areas, and the plan is to create a crop that contains a richer supply of nutrients.
29
Yes, I've read about that.
30
They're trying to produce rice that'll supply high levels of vitamin A in particular, aren't they?
31
Yes, but in my dissertation I'd also like to show that GM crops can have uses beyond just supplying food.
32
Well, did you read about the planned use for tomato plants?
33
Yes, that's amazing.
34
They plan to use tomatoes to transport medicines, don't they?
35
Yes, that's right.
36
Transporting vaccines isn't easy because they're so fragile.
37
So they're hoping to make an edible vaccine using tomatoes, one that'll be easier to ship, store and even administer.
38
It's a really good example of the varied uses GM crops can have.
39
Exactly.
40
And I'm hoping to include a section on the work that's being done on trees, poplar trees in particular.
41
The aim is to create a tree that can soak up contaminants, like heavy metals, right out of the soil.
42
It's an incredible idea, isn't it?
43
A tree like that could potentially eradicate many of our current environmental issues.
44
Yes, the work they're doing should really persuade people just how good this type of biotechnology can be.
45
Before you hear the rest of the conversation, you will have some time to look at questions 8 to 10.
46
Now listen carefully and answer questions 8 to 10.
47
I think articles like that can be very useful, don't you?
48
I agree.
49
It's important to reach out to the general public and show that biotechnology shouldn't be feared.
50
Yes, and the writer certainly covered a lot of the new food crops under development.
51
It's good to have the very latest information.
52
Things have clearly changed a great deal over the last few years.
53
That's right.
54
It could have been a bit more balanced in its approach, though, don't you think?
55
I suppose so.
56
There was really only one side presented.
57
People do need to have all of the facts, and this article didn't really do that, did it?
58
No. I suppose the aim was to provide a convincing argument for GM crops.
59
And what did you think about the proposed change to regulations?
60
Well, the writer was certainly very enthusiastic about it, but I have to say what they're suggesting sounds pretty alarming to me.
61
I'd have to agree with you there.
62
The plan is to give farmers more control
63
so they get to decide whether testing of any of their new GM crops is needed
64
and I'm struggling to see why they would want to do that.
65
I agree.
66
It's bound to make the public feel even more uneasy than they are at present.
67
It's certainly not going to win over anyone who already has their doubts about GM crops.
68
And I do think the public has a right to know about potential problems.
69
Even many scientists still have concerns.
70
Yes.
71
I used to think the only real concern was that these crops could spread uncontrollably and affect natural crops.
72
But that's not the case, is it?
73
That's certainly one issue.
74
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.
75
I guess that's something that definitely needs to be researched thoroughly, and the public would need to feel reassured about.
76
Yes.
77
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.
78
It seems like there's a long way to go yet.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
