Read the letter below and answer the five questions.
(1)How long has Jemma been at university for?
(2)How many brothers do both Jemma and Tracy have?
(3)What subject does Tracy’s mother teach?
(4)How many coincidences does Jemma mention?
(5)What’s the name of Jemma’s best friend?
Dear Hannah,
Now I’ve been here for a week I’ve started finding my way around. The lectures are OK and it’s fun being at university – no one to keep on telling me what to do!
Last night I went out with a couple of girls from my course and we got talking about everything. You’ll never believe it, but one of the girls – Tracy – is just like me! What do I mean?
Well, her birthday is on the same date (and how many people do you know who are born on February 29th?). We both have two brothers, although one of Tracy’s is older than her. Her mother is a teacher, and, unbelievably she teaches the same subject as mine. But that’s not all.
You know how I like to drink cold tea … yep! You’ve guessed it, so does Tracy! Also we both like the same pizza – ham and pineapple – but then I guess that’s not so unusual. But the strangest thing of all is that we both started learning to swim last year!
Now you know that I don’t really believe in coincidences and I’m not superstitious, but how do you explain all these things? And, of course, we’re studying the same course at the same university. Amazing, isn’t it?
Anyway, I’m missing you. Write soon.
Your best friend,
Jemma
