Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. ROUTINES Think about your daily life. Do you follow the same road to work everyday? Do you sit in the same place in class? When you get dressed, do you always put the same leg or arm in first? You probably do, because we all have routines in our lives. Routines save time and energy because you do them without thinking, that’s why they are so important in the morning when your brain isn’t active. Here’s Jo talking about her morning routine. ‘Oh yes, I always do exactly the same things. I wake up at seven o’clock every morning, but I don’t get up till quarter past seven. I switch on the radio and listen to the news. Then I go to the loo and I brush my teeth. I have a shower and dry my hair. Then I choose my clothes and I get dressed. I don’t eat anything for breakfast. I just have a cup of coffee. Then I go to work. Yes, It’s always the same.’ Routines are very useful, but they also make you uncreative. So sometimes it’s a good idea to break your routines. Get out of bed on the opposite side. Listen to a different radio station. Take a different route to work. Eat something different for breakfast. Change your routine. You never know, it could change your life. 41. This passage is mainly concerned with . A. our usual ways of doing things B. our daily activities C. Jo’s timetable D. changes in our life 42. According to the passage, routines are useful because __________. A. we can do them in the morning B. they make a habit of never thinking C. they save time and energy D. we all have them in our life 43. The word ‘loo’ in line 7 can be best replaced with .

People who have routines are unable to think. C. We shouldn’t break our routines. D. Our lives could be changed if we change our routines.
