Ex.1. The paragraphs of the text are mixed. Read and put them into the correct order.
Julia’s working day.
a) Now, let me describe my usual working day. My classes begin at 8:30. So on weekdays I have to get up at 7:15. I don't have an alarm clock and usually my roommate wakes me up and my working day begins. I turn on the radio and do my morning exercises while Natasha takes a shower. I don't take a bath in the morning because I don't have enough time for it. I take a cool shower.
b) After that, I go back to our room and get dressed. I brush my hair and put on a light make-up. Then we have breakfast. Natasha makes breakfast every Monday, Wednesday, and Friday. I have to serve breakfast on Tuesdays, Thurs¬days, and Saturdays. I love to listen to the latest news on the radio while I am eating and Natasha prefers light music.
c) Occasionally I have to stay at the Academy till 5 or even 6 o'clock in the evening because I go to the library to get ready for my practical classes or to write a report. As a rule, I have no free time on weekdays. We come home at about 7 o'clock in the evening. We have supper together and share the latest news.
d) I am a first-year stu¬dent of the Technical Academy. My parents live in Sochi and I study in Rostov-on-Don so I need some housing. There are two opportunities for me: I can live in a dor-mitory (a students hostel), or to rent a flat (an apart¬ment).I decided to rent a flat. To make the rent smaller, I also decided to share my flat with another girl — Natasha Kozlova. She studies at the Academy, too, and she is my best friend now.
e) At 11:50 we have lunch. That's my favourite time. That is the time to share the latest news and to gossip. My friends and I prefer not to go to the canteen and we often have lunch in a small cafe not too far from the Aca¬demy. At 12:30 we have to be back to our classes. Dur¬ing the working day we also have several short breaks that last for ten minutes.
f) We leave the house at ten minutes past eight and walk to the nearest bus-stop. We live rather far from the Aca¬demy and it usually takes us about a quarter of an hour to get there by bus. Sometimes when the weather is fine and we have enough time we walk to the Academy.
The classes begin at 8:30 in the morning and they end at 2:00 p.m. We have lectures in different subjects. As a rule we have three or four classes a day.
g) After supper we wash dishes, drink coffee or tea and watch TV. Sometimes Natasha and I go for a walk in the park or visit our friends. At about eleven at night I go to bed.
