Hi, my name is Ben. My daily routine starts early, at 6 am. I get up and go outside to do some
exercise or ride a bike. When I finish I go home, have a shower and get dressed. My clothes and
my bag are always ready from the night before.
Then I generally make a cup of coffee, check my e-mail inbox and have a look at the news in the
Internet. I eat my breakfast. I usually have eggs, sandwiches or biscuits for breakfast. I leave my
home at half past 8, take a bus and normally get to the school at 8.50 as there are no traffic jams
on my way. The lessons start at 9.00 in the morning, so I have some time to talk to my friends. I
like the atmosphere at my school: the teachers are cool and I meet my friends there. We go
for
lunch to our school canteen at 2 o'clock. I usually finish my studies at about 4 p.m. Though
sometimes we need to stay late to do some projects or work in the library. Then I go home, make
myself some dinner, switch my laptop on and surf the net. Then I do my homework. I also try to
read every evening. I go to bed at about midnight. That's my typical day.
The best part of my day is the evening when I have my dinner, watch TV, play computer games
or go out with my friends, watch football with Dad and just relax after a busy day. That's my
favourite time of the day
