Плоскость , параллельная ребру СС1, - это диагональное сечение ВВ1D1D , так как СС1║ВВ1 , ВВ1 ⊂ СС1В1В и СС1 ⊂ СС1В1В (СС1 и ВВ1 - противоположные рёбра одной и той же грани куба СС1В1В).

Первый текст.
The positive side of the job is 1--- getting
to see a lot of plays and shows which I love.
But the really great thing about being a theatre
critic is that, as theatre is an ongoing thing,
something that's going to be repeated night
after night for some time, there's also the
feeling that you may have a 2--
impact on the work. If the
producer or the actors read what you've written and agree with you,
they might actually change something and improve the
performance. That's not something that fiIm or book critics can do.
Some critics also iike making friends with the stars and all that - but personally I don't.
For me the worst part of the job is all the travelling. Getting there
on time, parking, getting back to the office to write for a nightly
deadline. That all gets really stressful. Another awfuI thing is that
editors 3 --- bits from your review without you knowing. You
learn as a critic that if you've got anything 4---, say it straight
away because it might not get printed. I once wrote a review of a
play by Julian Mitchell called Another Country.I didn't like it
much, but there was a new young actor who I thought was great,
called Kenneth Branagh. That was in the last paragraph and it got cut, so it looked as if I'd never 5-- this great new talent

Второй текст
The plus sides - I must have seen some
of the most spectacular moments in
cricket and football over the past forty
years. I've also had the 6--- to
travel to places I wouldn't have seen
otherwise, like India, Australia, New
Zealand, the Caribbean, South Afiica and Fiji. There are
much 7--- ways to make a living and it's great to get
away from Britain as much as you can during the winter.
One of the main dovrmsides is the 8----. You don't work
regular hours - you can spend a couple of days not working,
but you never relax because you're waiting for the phone to
ring. And then, when a story breaks - it might be on your
day off, it might be in the middle of the night - you just have
to 9--- everything and go. And you never know what
time you're going to be home. Another thing is the constant
tavelling. It's been fantastic visiting the Taj Mahal or spending
Christmas Day on the beach in Australia, but it does get
lonely and it can also be very l0----. I've spent a large
proportion of the last forty years driving up and down the
motorways of Britain, which I can assure you isn't much fun.
