Part 4.
2
You will hear part of an environmental studies lecture on tree planting.
3
First, you have some time to look at questions 31 to 40.
4
Thank you.
5
Now listen carefully and answer questions 31 to 40.
6
Tree planting now dominates political and popular agendas and is often presented as an easy answer to the climate crisis,
7
as well as a way for business corporations to offset their carbon emissions.
8
But unfortunately, tree planting isn't as straightforward as some people think.
9
When the wrong trees are planted in the wrong place,
10
it can do considerably more damage than good,
11
failing to help either people or the environment.
12
Reforestation projects are currently being undertaken on a huge scale in many countries,
13
and it's crucial that the right trees are selected.
14
A mix of species should always be planted,
15
typical of the local natural forest ecosystem and including rare and endangered species in order to create a rich ecosystem.
16
It's important to avoid non-native species that could become invasive.
17
Invasive species are a significant contributor to the current global biodiversity crisis
18
and are often in competition with native species and may threaten their long term survival.
19
Restoring biodiversity that will maximise carbon capture is key when reforesting an area,
20
but ideally any reforestation project should have several goals.
21
These could include selecting trees that can contribute to wildlife conservation,
22
improve the availability of food for the local community and maintain the stability of soil systems.
23
Meeting as many of these goals as possible,
24
whilst doing no harm to local communities,
25
native ecosystems and vulnerable species,
26
is the sign of a highly successful tree planting scheme.
27
To ensure the survival and resilience of a planted forest,
28
it's vital to use tree seeds with appropriate levels of genetic diversity,
29
the amount of genetic variation found within a species essential for their survival.
30
Using seeds with low genetic diversity generally lowers the resilience of restored forests,
31
which can make them vulnerable to disease and unable to adapt to climate change.
32
Choosing the right location for reforestation projects is as important as choosing the right trees.
33
Ultimately, the best area for planting trees would be informally forested areas that are in poor condition.
34
It's better to avoid non-forested landscapes,
35
such as natural grasslands, savannas or wetlands,
36
as these ecosystems already contribute greatly to capturing carbon.
37
It would also be advantageous to choose an area where trees could provide other benefits,
38
such as recreational spaces.
39
Reforesting areas which are currently exploited for agriculture should be avoided,
40
as this often leads to other areas being deforested.
41
Large scale reforestation projects require careful planning.
42
Making the right decisions about where to plant trees depends on having the right information.
43
Having detailed and up-to-date maps identifying high priority areas for intervention is essential.
44
Drone technology is a useful tool in helping to prioritise and monitor areas of degraded forest for restoration.
45
In Brazil, it's being used to identify and quantify how parts of the Amazon are being devastated by human activities,
46
such as rearing cattle and illegal logging.
47
A good example of where the right trees were picked to
48
achieve a restored forest is in in Lampang province in northern Thailand.
49
A previously forested site, which had been degraded through mining,
50
was reforested by a cement company,
51
together with Chiang Mai University.
52
After spreading 60 centimetres of topsoil,
53
they planted 14 different native tree species,
54
which included several species of fig.
55
Figs are a keystone species because of the critical role they play in maintaining wildlife populations.
56
They are central to tropical reforestation projects as they accelerate the speed of the recovery process by attracting animals
57
and birds which act as natural seed dispersers.
58
This helps to promote diversity through the healthy regrowth of a wide range of plant species.
59
Unlike the majority of fruit trees,
60
figs bear fruit all year round,
61
providing a reliable food source for many species.
62
At this site, for example,
63
after only three rainy seasons,
64
monkeys started visiting to eat the fig fruits,
65
naturally dispersing seeds through defecation.
66
Reforestation projects should always aim to make sure that local communities are consulted and involved in the decision-making process.
67
The restoration of mangrove forests in Madagascar is an example of a project
68
which has succeeded in creating real benefits for the community.
69
Destruction of the mangrove forests had a terrible impact on plant and animal life and also badly affected the fishing industry,
70
which was a major source of employment for local people living in coastal areas.
71
The reforestation project involved hiring local people to plant and care for the new mangrove trees.
72
Millions of mangrove trees have now been planted,
73
which has resulted in the return of a healthy aquatic ecosystem.
74
The mangroves also act as a defence against the increased threat of flooding caused by climate change.
75
What's more, the local economy is more stable and thousands more Madagascans are now able to send their children to school.
76
One other important point to consider...

Por que praticar a conversação com este vídeo?

Praticar a conversação em inglês com vídeos como o "Cambridge 19 Listening Test 4 Part 4" oferece aos alunos uma rica oportunidade de aprimorar suas habilidades orais. A palestra sobre plantio de árvores não apenas aborda questões ambientais relevantes, mas também ensina vocabulário técnico e expressões que podem ser utilizadas em discussões sobre ecologia e sustentabilidade. Ao se engajar com esse conteúdo, você melhora a sua fluência e se familiariza com o inglês usado em contextos acadêmicos e profissionais, tornando sua prática de conversação em inglês mais significativa e aplicável.

Gramática e Expressões em Contexto

O vídeo apresenta várias estruturas gramaticais que são úteis para alunos de inglês. Aqui estão algumas delas:

  • Verb to be + presented as: Essa estrutura é usada para descrever como algo é visto de uma certa maneira, como em "tree planting is often presented as an easy answer".
  • Modal verbs: A utilização de verbos modais como "should" e "could" mostra sugestões e possibilidades, importantes para discussões sobre planos e ações recomendadas, como em "should have several goals".
  • Conditional sentences: A estrutura de frases condicionais, como "if the wrong trees are planted", permite que você expresse consequências e condições, uma habilidade crucial na conversação.

Essas estruturas incentivam a prática do shadow speak, onde você pode repetir frases imediatamente após ouvi-las, ajudando na internalização de formações gramaticais. O shadow speech é especialmente eficaz para construir confiança em utilizar essas expressões em conversas reais.

Armadilhas Comuns de Pronúncia

O vídeo contém algumas palavras e expressões que podem apresentar desafios de pronúncia. Preste especial atenção nas seguintes:

  • Reforestation: A ênfase na sílaba correta pode ser confusa. Pratique dizer "ree-fo-re-sta-tion".
  • Biodiversity: Essa palavra longa pode ser um desafio. Uma dica é dividi-la em partes: "bio-di-ver-si-ty".
  • Invasive species: A pronúncia de "invasive" pode ser enganosa. Pratique a fonética "in-ve-siv".

Para melhorar a sua pronúncia, recomenda-se o uso de shadowing em inglês, onde você imita a pronúncia do falante. Isso ajudará a desenvolver a sua capacidade de intonação e ritmo durante a fala.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
