A. Read about the problems some people have (a—e) and match them with the solutions
(1—4) other people offer for such situations. There is one problem you don’t have
to match with a text.
1. If this is my problem, I first try to count up to a hundred,
if that doesn’t work, I close my eyes and I say in
my mind: “I’m going to sleep and I’m going to have
a very long and deep sleep or I may get up, have a warm
drink and read a bit.”
2. Well, I take as much exercise as I possibly can and I
try not to think about this problem of mine. Because if
you start thinking about it, you can be sure that you’ll
eat much more than you usually do and that will lead to
obesity. The best thing to do is to keep yourself busy
and do as many things as you possibly can.
3. In this case I try to be wise and analyze the situation.
I usually say to myself: “Hey, you can’t have all illnesses
imaginable. You have simply got stressed and that’s
why your heart is beating faster, you’re not having
a heart attack. You’re having a headache because
you’re tired and you haven’t had enough sleep. Everything
is OK with you.” But if I can’t calm myself, I go
to see a doctor.
4. If I have this problem, I just eat as many oranges as I
possibly can to get more vitamin [ˈvɪtəmɪn] C and take
a lot of hot drinks, not necessary milk which I don’t
like very much. I may stay in bed for a day or two.

d) I find new
and new diseases
I have.
a) I have a cold.
b) My problem is
sleeplessness.
c) I want
to lose weight.
e) I want to put on
weight as I’m getting
really skinny.
