I'm taking a test and have to guess the right answer to the question after the article. Article: In the most southern part of our planet, there's a place that's covered with snow and ice all year round. But it has the clearest and cleanest air. Amazingly, in this place, the sun sometimes hangs even in the midnight sky. This place is Antarctica : the coldest, windiest and harshest place on the Earth. As the world's least-known place, Antarctica is of great interest to scientists around the world. In 1983, China joined the Antarctic Treaty (<<>> ). The treaty made Antarctica a peaceful place for member countries to do scientific research. During 30 years, China has sent many scientists to Antarctica. They mostly look at the resources under the icy land and do research about climate change and marine biology. Antarctica is a place with fantastic views. However, life there is very hard. Food is one of the biggest problems. Frozen food which can be heated easily is people's daily food. Fresh vegetables are hard to grow in the cold weather. Therefore, scientists often eat dried or canned vegetables. Sleep is also troublesome. In Antarctica, summer lasts from November to March. During this period, Antarctica points to the sun and receives sunlight 24 hours a day. In order to get some sleep, scientists cover the windows with black plastic cloth to create "night". Working in Antarctica is dangerous, especially when meeting gale-force winds.Sometimes the wind is even stronger than a typhoon.It can easily blow people away.So there are ropes that connect buildings of some research stations.People can hold these ropes to keep their balance in forceful winds. What's more, communicating with others is difficult. Without cables and Internet in some research stations, two-way radios are the only tools to communicate. If people want to say hello to friends and relatives, they can use satellite phones. Although it is challenging to work in Antarctica, scientists' _ to learn about this mysterious land will never end. It is hopeful that one day they will step every corner of this icy land. Question: The passage is mainly about _ . Options: A: view of the Antarctica B: exploring the Antarctica C: how to survive in the Antarctica D: climate changes of the Antarctica

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: It's very early in the morning and I'm sitting outside. It's also very cold and dark.

After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin ," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus , and it's beautiful. "Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?" "Birds can sing any time of the year but the best time is the end of winter and during the spring. This is when the birds sing most." "Really? So, why do they sing?" I ask. "Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male." I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?" "That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also the female likes songs with different notes. Some birds, for example the European wren, have songs that contain over 700 different notes per minute!" So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common... Question: A bird sings early in the morning mainly _ .
