Air pollution levels have been rising steadily during seasonal transitions, affecting public health and the environment.
6
The levels across the capital are climbing, particularly during seasonal transitions with emissions crossing provincial boundaries.

9
Air pollution is not a new problem for Hanoi.
10

So far, authorities are deploying management measures and advanced technologies, including UAVs, to monitor rise,
12
straw burning and dust emissions from major construction sites across the city.
13
The monitoring results are shared promptly with local authorities to enable timely action.

Now, let's take a look.

According to the Department of Environment,

Since September, the Ministry of Agriculture and Environment Center for Agricultural Monitoring has deployed UAVs equipped with imaging and LIDAR systems.

¿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.
