teenagers are not just being lazy. Their biological clocks

sleepiness, starts to be secreted in the brain
much later at night and
later in the morning.
Researchers have found that student do worse in exams when they
them in the morning compared with in the afternoon. 'Teenagers' body clocks can be
delayed by between two and four hours, and they don't start to
until at least 10 a.m.', says professor Russell Foster, a neuroscientist at Oxford
university. 'The timetable is not very well thought
It is cruel to impose a cultural
on teenagers that make
them underachieve,' he adds. 'Most schools' regimes force teenagers to work
at a time of day that is suboptimal, and
many university students are
to considerable dangers
from sleep deprivation,' Prof. Foster says.

'That doesn't mean we are not supposed to have them take out
the rubbish and be part of the family. But it does
teach us that there are enormous changes going on inside their brains.
'I think the most
thing it teaches us is that
they aren't finished yet. That helps us to be a little bit more patient.
Teenagers may look grown up but they
are not grown-ups.
There is still a lot of development
in their brains.'

||Margaret's report on 'Language Development in Two-Year-Old Twins'
represents a year's painstaking work.
The case study shows various strengths,
particularly acute observations but the material
could have been more efficiently organised.
The paper was perhaps over-ambitious since it extended
10,000 words instead of the recommended 5,000.
||The writing is lively but too colloquial
for this kind of text. Margaret is also sometimes
inaccurate in her choice of vocabulary,
with unfortunate results.
||The project is pleasantly illustrated with photographs
and some useful charts, though it is a pity these were not original.
The work is marred by a number of typing and spelling
errors and would have benefited from stricter
proof-reading before submission.
