нужно прочитать текст и сделать 4 номера по соответствию а ,б или с .20 баллов кто правильно сделает.
23rd December: We have almost reached the Antarctic after two months at sea.Although it is summer here and there are 24 hours of sunshine, it’s still freezing and there are huge icebergs everywhere.One of our tasks while we are here
is to check the numbers, movement and feeding behavior of the penguin
colonies. We do this by capturing them and putting electronic tags on them. We have to be very careful so that no penguin is hurt.
24th December: Today we sang Christmas carols to our new
friends.They clapped their flippers to show they liked the singing. We
also saw a family of blue whales. They must have heard our singing.
What an amazing sight! The whale calves swam alongside their
mothers. It was a touching scene and one we shall never forget.
25th December: Happy Christmas!
The crew traditionally exchange
presents on these expeditions.Some of them were
disappointed, though, because their presents were underneath food
supplies and other equipment. We had expected to reach the Antarctic
research station earlier but recent bad weather has delayed us. Anyway,
Christmas dinner was delicious. We had roast turkey and Christmas pudding.
26th December: Today we played games on the deck such as sticking
our heads in buckets of freezing water.
Thinking about it now, this was crazy and dangerous! Soon
we are going to reach our base. Then we can start our research on the penguins. After we have done that, we can begin our albatross project.
Checking the weight of albatross chicks is the job of Juan, a biologist from university of Barcelona.
