Exercise 4 – Completed Paragraph 

Last year, our class went on a school trip to Chennai. We were extremely **excited** about visiting a new city. Because it was our first trip near the sea, our teacher asked us to sit quietly **and** listen to the safety instructions carefully. When we reached the railway station, we waited for our train on platform number **five**. Ravi forgot his water bottle, so he felt very **upset** about it. The teacher reassured him **and** told him that he could share with a friend. After the train arrived, we quickly found our seats. While looking out of the window, we saw green **fields**, small villages, and wide rivers. Meera wanted to read a storybook, and Raj wanted to play a game. They agreed to take turns **to** avoid any argument. Although the journey was long, everyone remained cheerful. 

Exercise 5 – Sample Paragraph 

A rainy day in my city feels fresh and peaceful. Dark clouds cover the sky, and cool winds blow through the streets. People carry umbrellas and walk carefully on the wet roads. Children enjoy jumping in puddles near their homes. The trees look greener after the rain, and the air smells clean. Although traffic moves slowly, the weather makes everyone feel calm and happy.
