However, they can be difficult for students living far from schools. Online classes offer flexible learning from home, which is helpful during emergencies like the pandemic. But many students face problems like poor internet and power cuts. While offline classes provide personal contact, online classes offer convenience. A mix of both could improve education in Bangladesh.

The Inauguration of the Dhaka Metro Rail
Staff Correspondent, Dhaka | [Date]

In a landmark event for Bangladesh’s transportation sector, Prime Minister Sheikh Hasina officially inaugurated the Dhaka Metro Rail on December 28, 2022, at the Diabari Depot in Uttara. This historic moment marks the beginning of a new era in public transport for the capital city, aiming to reduce traffic congestion and enhance urban mobility.

The inauguration ceremony was attended by ministers, government officials, engineers, and enthusiastic citizens. The Prime Minister expressed pride in the nation's achievement and highlighted the Metro Rail as a symbol of Bangladesh's rapid progress in infrastructure development.

The Mass Rapid Transit (MRT) Line-6, stretching from Uttara to Motijheel, is the first of its kind in the country. The initial phase, from Uttara North to Agargaon, became operational first. The full line, once completed, will cover approximately 20.1 kilometers with 16 stations, serving thousands of commuters daily.

Equipped with state-of-the-art technology, the metro rail promises fast, safe, and eco-friendly transport. It will significantly cut travel time, improve traffic conditions, and reduce pollution in the city.

The successful launch of the Dhaka Metro Rail is a major step toward building a modern, smart Bangladesh. Authorities have urged the public to use and maintain the service responsibly, ensuring its long-term success.

The phrase "is said to be" is a passive construction that becomes "people say that..." in the active voice

The sentence "Whom did you see on the road?" is in the active voice.

The sentence "The book contains useful information." is in the active voice.

The sentence "Please keep off the green." is in the active voice and imperative form.

Passive voice:
You are requested to keep off the green.

Explanation:
Imperative sentences in passive voice are often changed using structures like "You are requested to...", "You are advised to...", or "Let..." depending on the tone.

"Keep off the green" means "do not step on the grass," and in passive, we use "You are requested to..." to keep the politeness and intent.

Explanation:
"If I were you" is a subjunctive expression used for imaginary or hypothetical situations.

The correct verb form to follow is "would not support", expressing what one would do in that unreal situation.
