1
You will hear part of a lecture about the use of different building materials.
2
First, you have some time to look at questions 31 to 40.
3
Thank you.
4
Now listen carefully and answer questions 31 to 40.
5
Good morning, everybody.
6
Can you all hear me?
7
Good.
8
Well, today I'm going to be talking about construction materials, where they come from and what their properties are.
9
First of all, then, what are the sources of the materials we use in construction?
10
Well, many of them are manufactured.
11
Plastic is one example.
12
Others are natural.
13
But even naturally occurring materials usually require processing before they can be used.
14
Wood, for instance, is rarely used directly from trees.
15
Instead, this natural material is first cut into required lengths and then seasoned to remove the excess moisture.
16
The result is what we call timber.
17
And then timber itself is often treated with preservatives before use, especially if it's going to be used on the outside of a building.
18
In a similar way, stone needs to be cut to shape and may also be polished before being used for building.
19
Of course, the more processing that's required, the more expensive the material becomes.
20
What about selection?
21
When we're deciding which kind of material to use, cost is not the only consideration.
22
It's important to consider the effect on the environment, too.
23
The problem is, large amounts of energy are used.
24
For example, it takes huge amounts of energy to produce aluminium, and materials like timber need a lot of energy to transport because of their weight.
25
Well, that's enough about sources.
26
Let's move on to material properties, and let's first consider appearance.
27
Now, there's a vast range of materials used in the building industry, and they vary tremendously in their appearance.
28
Even for any single building material, appearance may vary greatly.
29
For example, brick and stone come in a very wide range of colours, and can be smooth or very rough.
30
And timber is especially interesting because the grain patterns on each piece, even from the same tree, are unique.
31
But properties have to be described very accurately for construction purposes, and that usually involves the use of mathematical formulae.
32
It isn't enough to say that a particular material is rough or strong or heavy.
33
Words are subjective and they can be ambiguous so verbal descriptions alone aren't enough.
34
Reflectance is a good example of this.
35
Precise values for a range of building materials are available.
36
Reflectance is a measure of the ability of a surface to reflect light, and a perfect reflector has a reflectance of one.
37
A polished, mirror -like silver surface has a reflectance of very nearly one.
38
A plaster surface, which has been painted brilliant white has a reflectance of around
39
0 .8 quarry tiles have a reflectance of about 0 .1
40
and black velvet has a reflectance of nearly zero well let's
41
move on now to another very important property of materials that is the end of part four you now have one
42
One minute to check your answers to part four.

polish verbo/ˈpɑ.lɪʃ/lucidare, levigare
vary verbo/ˈvɛəɹi/variare
vast aggettivo/væst/ampio, vasto
naturally avverbio/ˈnæt͡ʃ.(ə.)ɹə.li/naturalmente
mirror sostantivo/ˈmiɹɚ/specchio
occur verbo/əˈkɜː/verificarsi

consideration sostantivo/kənˌsɪd.əˈɹeɪ.ʃən/considerazione
involve verbo/ɪnˈvɑlv/coinvolgere

Pronuncia a cui fare attenzione

Chi parla usa 4 contrazioni e forme ridotte, come aren't, I'm, isn't. Pronunciale nella forma breve, così come le senti.

  • I suoni “th”: smooth /smuːð/, mathematical /ˌmæθ(.ə)ˈmæt.ɪ.kəl/
  • I suoni “sh” e “zh”: polish /ˈpɑ.lɪʃ/, consideration /kənˌsɪd.əˈɹeɪ.ʃən/
  • Parole lunghe — attenzione all’accento: naturally /ˈnæt͡ʃ.(ə.)ɹə.li/, consideration /kənˌsɪd.əˈɹeɪ.ʃən/, mathematical /ˌmæθ(.ə)ˈmæt.ɪ.kəl/, accurately /ˈæk.jə.ɹɪt.li/, aluminium /ˌæl.(j)uˈmɪn.i.əm/

I suoni difficili per chi parla italiano:

  • Consonante finale — senza aggiungere una vocale dopo: polish /ˈpɑ.lɪʃ/, vast /væst/, reflect /ɹɪˈflɛkt/, involve /ɪnˈvɑlv/, brick /ˈbɹɪk/
  • /æ/ — più aperta della “e”: vast /væst/, naturally /ˈnæt͡ʃ.(ə.)ɹə.li/, mathematical /ˌmæθ(.ə)ˈmæt.ɪ.kəl/, accurately /ˈæk.jə.ɹɪt.li/, aluminium /ˌæl.(j)uˈmɪn.i.əm/

Come esercitarsi con questo video

  1. Ascolta tutto il video una volta senza parlare e annota le parole che non conosci.
  2. Fai shadowing frase per frase a velocità normale, ripetendo ognuna finché il tuo ritmo coincide con quello di chi parla.
  3. Registrati e confronta con l’originale, facendo attenzione a parole come timber, polish, vary.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
