1
In Europe, the green economy comprises of renewable energy,
2
electric vehicles and often specific types of markets such as building materials.
3
In Belgium, a company is transforming excess grass from riverbanks,
4
canals, parks and urban areas into bio-insulation panels for homes and buildings.
5
Let's find out more in a report from the Vietnam Television Correspondent Team in Europe.
6
Instead of being discarded, grass cut from canal banks,
7
river banks, parks or urban areas in Belgium is being processed into a new production line.
8
At a Belgian company's factory,
9
this grass is used to produce bio-insulating panels for the construction industry.
10
Notably, this is not grass grown on agricultural land.
11
The company does not use cultivated land,
12
does not need irrigation and does not use fertilizers or pesticides to produce the raw material.
13
When trucks carrying dry grass arrive at the factory,
14
the material is checked for moisture content,
15
then put through a cleaning system to remove dust and impurities such as wood, stone or metal.
16
The grass is brought here.
17
We work in bulk in bulk
18
so there's a truck coming with a walking floor who pushes all the grass behind us
19
and after that is done the whole building behind me is used to treat the grass
20
so we remove all the dust and fine particles of the grass
21
and then we also remove all the pieces of wood
22
stone metal that we can also find in the grass we do this
23
because the grass that we are using is not coming from agricultural land
24
so it can contain other pollution that we don't want into your final product.
25
After cleaning, the grass is mixed with recycled jute fibers from old coffee and cocoa bags and a binder.
26
According to the company, the finished material consists of approximately 70% grass,
27
20% recycled jute fibers and 10% binder.
28
The fiber mixture then passes through a conveyor belt and is fed into an oven at approximately 160 degrees Celsius.
29
Upon exiting the oven, the fibers have formed flat sheets which are cooled,
30
measured for thickness, cut to standard dimensions and package for delivery to the construction site.
31
So we just cooked the panel so the raw material enters the oven and the oven is at 160 degrees.
32
So it's the same temperature as to cook a fish.
33
So we have a low temperature and low energy process
34
and once it gets out of the oven we are cooling the panel
35
and then it's ready to be cut into the the right dimension.
36
Not only does this production line create new materials from biological sources,
37
but it is also designed to minimize waste.
38
The excess material from cutting is crushed and returned to the production line.
39
The company also encourages customers to bring leftover materials back to the factory for recycling.
40
At the construction site, grass-based insulation panels are installed in walls and ceilings,
41
providing both thermal and sound insulation.
42
In Europe, this is a concrete example of the bio-economy utilizing local by-products,
43
partially replacing traditional materials and reducing the ecological footprint of the construction industry.
44
The story in Belgium shows that the green economy is not only about advanced technology,
45
sometimes it starts with a simple idea,
46
turning ordinary local resources such as roadside or cannon grass into products that create both economic and environmental value.

为什么要通过这个视频练习口语？
通过观看《越南今日》的这一视频，学习者可以接触到一个关于绿色经济和建筑材料创新的真实案例。这种内容不仅增加了对当今环保问题的认识，还提供了英语口语练习的良好机会。与视频中的讲述者一起练习，可以帮助提升你的发音和流利度，学习如何在特定话题上进行表达。同时，学习者可以学习如何用英语讨论类似的环保和可持续发展的主题，这在当今社会中显得尤为重要。通过看YouTube学英语，你可以将日常生活中的对话融入学习，使得学习变得更加生动和实用。
语法与表达的上下文
在视频中，讲述者使用了几个重要的语法结构和表达方式，这里有三个例子供学习者参考：
- 现在进行时：用于描述正在进行的动作，例如“当卡车载着干草抵达工厂时…”。这种时态在叙述流程时尤为常见。
- 被动语态：在讲到“草被处理成新生产线”时，体现了重心放在动作的承受者而非执行者的表达方式，适合在专业场合使用。
- 条件句：如“如果草来自农业土地，它可能会包含其他污染物”，帮助学习者理解因果关系的表达方式，这对于讨论复杂话题非常有用。
常见发音陷阱
在视频中，有几个单词可能会对学习者造成发音上的挑战：
- insulation（隔热材料）：此单词的重音通常放在第三个音节上，不熟悉的学习者需要特别注意。
- sustainable（可持续的）：发音中的“sustain”的“tain”部分常常被误读，跟读和模仿是提高发音的有效方法。
- recycled（回收的）：这个词的“cy”部分容易发错音，需要反复练习才能掌握。
通过英语口语练习和英语影子跟读的方法，学习者可以有效地克服这些发音障碍，增强语言的自信心。试着在适合的语境中，多次练习视频中的对话，以帮助你在实际交流中更流利地表达自己的想法。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
