Band 8 sample answer
The change I'd like to describe is the Orange Line, the metro train in Lahore, which is where I grew up. It opened in October 2020, although for my family the story really began about four years earlier, when the construction started.
Those years were, frankly, chaotic. The line runs on a raised track through some of the busiest parts of the city, so for a long time whole roads were dug up, and a journey that used to take twenty minutes could take an hour. There was also a lot of argument about it, because the route passes close to some old historic sites, and people were worried about damage to them.
Once it opened, though, the effect was quite dramatic. My aunt, for example, works as a teacher on the other side of the city. Before, she had to take two minibuses, and in summer, when it's over forty degrees, she'd arrive at school exhausted. Now she's on an air-conditioned train for most of the trip, and it costs her less than the bus did. A lot of students and office workers I know say the same thing: it's given them back about an hour a day.
As for how I feel, I'd say mostly positive, but with some reservations. It's made the city feel more connected, and it's a real improvement for women in particular, who often felt uncomfortable on crowded buses. On the other hand, it only covers one route, so most people still depend on cars and motorbikes, and the traffic hasn't really improved. So it's a good start, but I don't think one line can fix a city of that size.
