Установите соответствие между текстами А -G и заголовками 1-8. Занесите
свои ответы в таблицу. Используйте каждую цифру только один раз. В задании
один заголовок лишний.
1. Flower shop 5. Animal visit
2. Part-time job 6. Daily spotlight
3. Caring for animals 7. Indoor chores
4. Gardening jobs 8. Daily wake-up
A. Some people might think working round the house is an easy thing, but these people obviously don’t
do very much of it. W hen you have to tidy up a living room full of kids’ toys, clean bookshelves covered
in dust and prepare a meal for suppertime, it can be exhausting. You can’t do it alone, so you’ve got
to employ your family to help. Still, they don’t always do their jobs!
B. Being a florist is a rewarding job. It’s almost like being a decorator of plants. You make all sort
of arrangements in a variety of colours for special occasions like weddings and M other’s Day, and
naturally, you have to be a lover of all things green. You’ve got to make sure all the plants stay healthy
otherwise it’s hard to make a sale.
C. Working as a TV newsreader has its ups and downs. The up side is if you love communicating and
think you do it well, it’s the perfect job for you. On the other hand, it can be quite stressful being on
camera often, especially when you don’t feel like it. Additionally, the news is often not pleasant to
report on, so you’ve got to keep a stiff upper lip.
D. If you’re looking for some extra money, you might want to consider working for a few hours after
school. Lots of places are keen on employing young people, and the work schedule can be quite flexible.
A student has a busy life, so you probably couldn’t do more than ten or twelve hours a week, but it’s
a great way to earn some cash and learn responsibility.
E. For many adults, the first thing to do every m orning is to grab a cup of coffee and sit down with the
news. Whether it be reading a paper or the internet, it seems to be a habit for lots of people. The news
has a way of kicking your m ind into gear, along with the coffee, of course, and then once you’ve had
your fill, it’s off to get ready for work.
F. Whereas some people don’t m ind doing housework, for others, it’s a real bother. They prefer being
outside, and if they’ve got a big garden to tend to, there’ll be many tasks to keep them entertained, such
as planting seeds, pruning trees and doing the watering. There’s something they can do outside every
day, and they never get bored with it.
G. There are lots of different class trips a teacher can take students on, like visiting a newspaper or a bank
to see how things are run. An interesting way to learn about nature is a trip to the zoo. The kids see lots
of different kinds of animals, and they can learn about where they’re from. It’s just one of many class
trip ideas.
