Part 4 You will hear part of a lecture on nanotechnology and its applications.
2
First, you have some time to look at questions 31 to 40.
3
Now listen carefully and answer questions 31 to 40.
4
Today's lecture is the first of a series of lectures on nanotechnology.
5
Nanotechnology, sometimes shortened to nanotech, refers to the manipulation of matter on an atomic and molecular level.
6
It's the science, engineering and technology conducted at the nanoscale, which is about 1 to 100 nanometres.
7
It is the study and application of extremely small things and can be used across all the other science fields.
8
Just how small is that?
9
A nanometre is one billionth of a metre.
10
The idea of nanoscale research first started from a physicist called Richard Feynman in 1959,
11
He envisaged a process in which scientists would be able to manipulate and control individual atoms and molecules.
12
In fact, it wasn't until 1981, with the invention of a special kind of microscope, that modern nanotechnology truly began.
13
Even though nanotechnology has created many new materials and devices with a vast range of applications, there is always concern over these unnatural products.
14
Many people are worried that they may pose a threat to the environment, health and safety, also known as EHS.
15
In order to better understand and evaluate the potential harm, risk assessment has been introduced.
16
There are also ongoing international collaborations on nanoEHS research and related policy issues.
17
Despite the concern nanotechnology has benefited society in unexpected ways, In the food processing industry,
18
nanotechnology is leveraged against iron deficiency, which triggers anemia.
19
For example, by reducing the particle size in potatoes,
20
this new technology improves the bioavailability of this nutritional ingredient without the tendency to cause colour and odour changes.
21
In terms of packaging, nanomaterials are more economical and are used in all sorts of products, chocolate in particular.
22
Nanotechnology can also enhance the flavour of food.
23
On a domestic scale, we expect more smart furniture, which is made of shape memory alloys, to be manufactured.
24
But nanotechnology has much wider application than this and could also help develop sustainable agriculture.
25
It offers great potential to strengthen the effect of fertilizers, thereby minimizing the environmental impact and boosting the productivity of plants in the soil.
26
In the area of medicine, bioengineers have developed simple and inexpensive nanoscale delivery vehicles,
27
Conductors like carbon nanotubes have been invented with varying structures.
28
Such nanotubes have become increasingly attractive to researchers because of their ability to efficiently deliver drugs into veins.
29
This means that higher doses of drugs loaded on them can be transported from the administration sites to the effects -related sites, such as cancer focuses.
30
thus decreasing toxic side effects while increasing the treatment effects.
31
The research team has also developed a widely accepted material that can be used to coat different surfaces, including wood, plastic and glass.
32
It is mainly comprised of silver.
33
Such nanoparticles can eventually kill some microbes due to the antiseptic properties.
34
The whole process is simple, easy to apply and, more importantly, harmless to the environment.
35
Surprisingly, nanotechnology has major implications for our health as well.
36
By changing the metabolic rate through a particular type of protein, obese patients are able to burn calories faster, even under a high calorie diet.
37
Therefore, treatment programs are provided for patients to lose weight by disposing of excess fat in a relatively safer manner.
38
The finding may help explain why overweight people struggle to lose weight.
39
Their stored fat is actively fighting against their efforts to burn it off at the molecular level.
40
Further research is mainly focused on the clinical and commercial developments of therapies for obesity,
41
diabetes and other associated conditions such as heart disease.
42
In terms of cosmetics, the applications of nanotechnology and nanomaterials can be found in many products.
43
There are two main uses for nanotechnology in cosmetics.
44
caused by the sun.
45
In addition, nanotechnology has played an important role in delivering active ingredients to the skin.
46
The mechanism proves to improve the bioavailability of actives and enhance skin hydration.
47
The wide variety of nanotechnology applications leave no doubt that this field will only continue to get more exciting,
48
and I look forward to seeing these developments further branch out.
49
That is the end of part four.
50
You now have one minute to check your answers to part four.

Сценарий: Лекция о нанотехнологиях

Представьте, что вы слушаете лекцию на английском в университете или смотрите образовательный видеоролик о современных науках. Текст видео — это реальная лекция, где объясняются основы нанотехнологий, их применение в медицине, пищевой промышленности и косметике. Такой контент отлично подходит для практики аудирования и произношения, так как он содержит научные термины, но при этом структурирован и понятно выстроен.

Полезные выражения и словосочетания

  • Manipulation of matter — манипуляция материей (ключевое понятие в науке)
  • Bioavailability of nutritional ingredients — биодоступность питательных веществ (важно для пищевой промышленности)
  • Drug delivery vehicles — средства доставки лекарств (термин в медицине)
  • Antiseptic properties — антисептические свойства (используется в описании материалов)
  • Metabolic rate — метаболическая скорость (важно для темы здоровья)

Ваше задание: Shadowing Challenge

Чтобы улучшить произношение английского и практику разговорного английского, попробуйте метод shadowspeak (или shadow speak). Выберите отрывок из видео длиной 30 секунд (например, фрагмент о применении нанотехнологий в медицине). Включите запись, услышите фразу, затем сразу повторите её вслух, копируя интонацию и темп говорящего. Проведите это упражнение 5–7 раз подряд. Этот метод поможет вам привыкнуть к естественной речи и улучшить своё произношение. Для лучшего результата запишите себя на диктофон и сравните с оригиналом — вы увидите прогресс уже через несколько дней!

Shadowing английский — это эффективный способ тренировки, который подходит как новичкам, так и продвинутым learners. Не бойтесь ошибок: главное — повторять и стараться копировать звуки и ритм речи.

Грамматика в этом видео

Конструкции, которые говорящий использует чаще всего, с точными словами из видео:

КонструкцияВ видео
Present Perfect have/has + причастие прошедшего времени — прошлое действие, важное сейчасhas created · has been introduced · has benefited
Пассивный залог be + причастие прошедшего времени — важно, что происходит, а не кто это делаетhas been introduced · is leveraged · is made
Придаточные определительные who / which + предложение — уточнение о человеке или предметеnanoscale, which is · furniture, which is

Что такое техника Shadowing?

Shadowing — это научно обоснованная техника изучения языка, изначально разработанная для подготовки профессиональных переводчиков и популяризированная полиглотом доктором Александром Аргуэльесом. Метод прост, но эффективен: вы слушаете аудио на английском от носителей языка и немедленно повторяете вслух — как тень, следующая за говорящим с задержкой в 1–2 секунды. В отличие от пассивного прослушивания или грамматических упражнений, Shadowing заставляет мозг и мышцы рта одновременно обрабатывать и воспроизводить реальные речевые паттерны. Исследования показывают, что это значительно улучшает точность произношения, интонацию, ритм, связную речь, понимание на слух и беглость речи — что делает его одним из самых эффективных методов для подготовки к IELTS Speaking и реального общения на английском.
