Lizzie's diary from Antarctica (南极洲)
Day 3: Tuesday December 2
We planned to go to Rothera that morning. We'd be staying there for the next two weeks. Because Antarctica is the windiest place on earth, sometimes you can't fly at all.
We had a nervous wait over breakfast to find out if we'd be leaving that day. People have to stay in Stanley for weeks while the pilots wait for good weather.
It turned clear at 9：30 and we took off at 10：30 on a little red plane called a Dash7. But even when we were in the air, there was still a chance(可能性) we wouldn't be able to fly the whole day.
Day 4: Wednesday December 3
After waking up in the Antarctic for the first time today I can understand why everybody who comes here falls in love with the place. It is really beautiful.
We're staying at Rothera Survey Base with mountains of ice all around. It's about minus 2℃ today，which for me is very cold，but the regulars(常客) here are often seen walking around in Tshirts!
Day 5: Thursday December 4
I woke up to another beautiful sunny day here in the Antarctic. I'm told it's
3
a bit colder today, about minus 5℃， but it's not very windy so it feels warmer. Those of us who are new to the base have to do a special training course before we're allowed to go off base to other stations or to go snowboarding over the nearby hill.
Day 7: Saturday December 6
Not a cloud in the sky and it's warm enough to sit outside (in a jacket)．
The most amazing thing about this place is how the scenery(风景) changes every day. At first I thought I was going mad. I'd step outside in the morning and think, “I'm sure that big mountain of ice wasn't there yesterday.” It's because the sea ice is always moving—slowly thankfully!
( )1.Lizzie sat outside wearing a jacket on ________．
A．Tuesday B．Wednesday
C．Thursday D．Saturday
( )2.What could stop Lizzie from leaving Stanley for Rothera?
A．Strong winds.
B．Thick clouds.
C．Mountains of ice.
D．Low temperatures.
( )3.How did Lizzie feel during her stay in the Antarctic?
A．Afraid. B．Nervous.
C．Amazed. D．Bored.
( )4.What impressed Lizzie most about Rothera was that ________．
A．people walked around in Tshirts
B．there was a special training course
C．the weather was sometimes warm
D．the scenery changed every day
