Greenland is a very different place from Hong Kong. It is the largest island in the world, but only 56,000 people live there. Greenland is a very interesting name, because 95% of the land is covered with white ice. For four months every year, it is night-time for 24 hours a day! The weather is often very cold and windy.
Julianehab is a small fishing village on the south coast (海岸) of Greenland. Not many people live there. Two of these people are Charles and Karent Luk from Hong Kong.
The Luks have lived in Greenland since 1993. "We first came here in 1988. At that time, we were both studying at a college in Hong Kong," said Charles. "We fell in love with Greenland and decided to live here." The Luks work for an international (国际的) company in Julianehab.
Charles and Karen are learning Inuit, the language of Greenland. However, most of the time they use English. "English is an international language," said Charles. "It helps people from Hong Kong to talk to other people from all over the world."
The Luks are very happy in Greenland and would like to stay there for the rest of their lives. "We like Greenland because it’s a very quiet place," said Karen Luk. "The people are very friendly. We also enjoy the food very much. Greenlanders like seafood, and so do we." What do we know about "Inuit" (Line 1, Para.4)

A. The Luks speak it to people from other countries.
B. It is a kind of international language.
C. It is a foreign language to the Luks.
