Activity 2: Read and conclude
Last summer holiday, I fell in love with online travel.
The day before yesterday, I decided to share my virtual trips with my friend Tom. Last week, I visited New York’s Times Square online—its bright lights amazed me! Two years ago, I only knew New York from books, but now I know its landmarks well. Just now, I showed Tom Liverpool’s Anfield Stadium virtual tour—he’s a football fan and got excited! A moment ago, we browsed London’s famous museums online too.
Circle the time adverbials used in the simple past tense.
Activity 2: Read and conclude
In 2022, my geography teacher told me about these city tours, and I’ve loved them since. During the winter holiday last year, I spent two afternoons exploring London’s cultural buildings. At the age of 12, I dreamed of visiting foreign cities; now online travel makes it real. On Sunday morning last week, I joined a virtual walk in New York’s Central Park. The other day, my sister told me about Liverpool’s music scene tour (birthplace of the Beatles), so I planned to try it. Once upon a time, traveling to the UK and USA seemed impossible, but online travel changed that. When I was in Grade 7, I never thought I could “visit” these places at home—what fun!
