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.
