$\text{indicate the correct answer to each of the Questions from 1 to 10.}$
We live in a world of tired, sleep deprived people. In his book Counting Sheep, Paul
Martin - a behavioural biologist - describes a society which is just too busy to sleep and which
does not give sleeping the importance it deserves. Modern society has invented reasons not
to sleep. We are now a 24/7 society where shops and services must be available all hours. We
spend longer hours at work than we used to, and more time getting to work.
Mobile phones and email allow us to stay in touch round the clock and late-night TV
and the Internet tempt us away from our beds. When we need more time for work or pleasure,
the easy solution is to sleep less. The average adult sleeps only 6.2 hours a night during the
week, whereas research shows that most people need eight or even eight and a half to feel at
their best. Nowadays, many people have got used to sleeping less than they need and they
live in an almost permanent state of'sleep debt'.
Until the invention of the electric light in 1879 our daily cycle of sleep used to depend
on the hours of daylight. People would get up with the sun and go to bed at nightfall. But
nowadays our hours of sleep are mainly determined by our working hours (or our social life)
and most people are woken up artificially by an alarm clock. During the day caffeine, the
world's most popular drug, helps to keep us awake. 75% of the world's population habitually
consume caffeine, which up to a point masks the symptoms of sleep deprivation.
What does a chronic lack of sleep do to us? As well as making us irritable and unhappy
as humans, it also reduces our motivation and ability to work. This has serious Implications
for society in general. Doctors, for example, are often chronically sleep deprived, especially
when they are on'night call', and may got less than three hours'sleep. Lack of sleep can
seriously impair their mood, judgment, and ability to take decisions. Tired engineers, in the
early hours of the morning, made a series of mistakes with catastrophic results. On our roads
and motorways lack of sleep kills thousands of people every year. Tests show that a tired
driver can be just as dangerous as a drunken driver. However, driving when drunk is against
the law but driving when exhausted isn't As Paul Martin says, it is very ironic that we admire
people who function on very little sleep instead of criticizing them for being irresponsible,
Our world would be a much safer, happier place if everyone, whatever their job, slept eight
hours a night

II. Read the passage carefully, then choose the correct option (marked A, B, C or D) to answer the questions.

A recent survey of crime statistics shows that we are all more likely to be burgled now than 20 years ago and the police advise everyone to take a few simple precautions to protect their homes.

The first fact is that burglars and other intruders prefer easy opportunities, like a house which is very obviously empty. This is much less of a challenge than an occupied house, and one which is well-protected. A burglar will wonder if it is worth the bother.

There are some general tips on how to avoid your home becoming another crime statistic. Avoid leaving signs that your house is empty. When you have to go out, leave at least one light on as well as a radio or television, and do not leave any curtains wide open. The sight of your latest music centre or computer is enough to tempt any burglar.

Never leave a spare key in a convenient hiding place. The first place a burglar will look is under the doormat or in a flower pot and even somewhere more 'imaginative' could soon be uncovered by the intruder. It is much safer to leave a key with a neighbor you can trust. But if your house is in a quiet, desolate area be aware that this will be a burglar's dream, so deter any potential criminal from approaching your house by fitting security lights to the outside of your house.

But what could happen if, in spite of the aforementioned precautions, a burglar or intruder has decided to target your home? Windows are usually the first point of entry for many intruders. Downstairs windows provide easy access while upstairs windows can be reached with a ladder or by climbing up the drainpipe. Before going to bed you should double-check that all windows and shutters are locked. No matter how small your windows may be, it is surprising what a narrow gap a determined burglar can manage to get through. For extra security, fit window locks to the inside of the window.

What about entry via doors? Your back door and patio doors, which are easily forced open, should have top quality security locks fitted. Even though this is expensive it will be money well spent. Install a burglar alarm if you can afford it as another line of defence against intruders.

A sobering fact is that not all intruders have to break and enter into a property. Why go to the trouble of breaking in if you can just knock and be invited in? Beware of bogus officials or workmen and, particularly if you are elderly, fit a chain and an eye hole so you can scrutinize callers at your leisure. When you do have callers never let anybody into your home unless you are absolutely sure they are genuine. Ask to see an identity card, for example.

If you are in the frightening position of waking in the middle of the night and think you can hear an intruder, then on no account should you approach the intruder. Far better to telephone the police and wait for help.
