Reading Comprehension Test
6th Grade 1 term
Read the text about Janet and do the tasks.
Janet is a sports coach and she's really interested
in her job. Janet wakes up at half past six every weekday
morning. She gets dressed and runs for thirty minutes
near her house. After running, Janet has a shower and
checks her email. Then she has breakfast, which is
usually cereal and fruit, and leaves the house at half past
seven in the morning.
She needs twenty minutes to drive to the gym. She
trains for three hours with her team and then she goes
home for lunch. Janet always eats a very big and healthy
lunch. Sometimes she has a snack or drinks her favourite
orange juice. She likes listening to music before she goes
to bed, but she never watches the television or reads
anything on her tablet.
Janet's favourite activity is swimming and her favourite
place is the beach in her city. She likes going there with
her best friend Abby. They often walk along the beach
and enjoy sounds of the sea.
Janet also likes travelling. Last year she and her
family went to France and had an exciting trip. They didn't
live in a hotel because their aunt lives in a big house in
Paris. Janet liked the trip. She went sightseeing, visited
famous museums and took some photos. In the city Janet
bought a lot of presents and clothes. The food was good
but the weather was rainy. Janet wasn't sad, and next
year she's going to visit a new country. (247 words).
