Pronunciación

Para sonar más natural en el examen, practica el 'linking' (unión de sonidos). Por ejemplo, en la frase 'it appears as though', el sonido final de 'appears' debe fluir suavemente hacia la vocal de 'as'. Practica la 'catenation' cuando una palabra termina en consonante y la siguiente empieza por vocal, como en 'striking contrast' o 'is indicative'. Esto evitará que tu habla suene entrecortada.

Model answer

🔊

In the former image, we can observe a person working late into the night, illuminated solely by the harsh, blue light of a laptop. The atmosphere is quite heavy, and it appears as though the individual is struggling with exhaustion, likely due to a disrupted sleep cycle. Conversely, the second picture depicts a much more serene scene where the same person is waking up naturally to the soft glow of the morning sun. There is a striking contrast between the frantic, artificial environment on the left and the tranquil, organic setting on the right.

Regarding the question of productivity, I would argue that the circadian rhythm plays a pivotal role. While the person in the first image might be attempting to be productive, the lack of restorative sleep likely leads to diminished cognitive function in the long run. In stark contrast, the second scene suggests a healthy alignment with natural light cycles. I believe that synchronising our activities with our biological clocks, rather than fighting against them with artificial light, is essential for maintaining peak mental performance and overall well-being. Ultimately, the first person is sacrificing long-term health for short-term output, which is often counterproductive.
