[单项选择]The discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called "the heroic age of Antarctic exploration". By their tremendous heroism, men such as Shekleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the techniques of former explorers, and, although still calling for courage and feats of endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogs that earlier discoverers found so invaluable.
Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately chartered, and the mapping of the whole of the interior presents a formidable ta

[填空题]Am I Making Any Money
Correct Most people and most businesses are in business to make a profit. At the
On simplest level, profit means making more money than you spend on. Many
34 confuse profit with income. As a result, they can’t grasp it why all their income
35 isn’t getting them ahead; why no one wants to invest in their high-sales
36 company; why the bank won’t extend to their line of credit. Most people are very
37 good at tracking their income. When someone pays for you, that is income.
38 Income is usually related to production levels, but is not tied to it directly. You

40 widgets in the warehouse when you receive an order for 150, you only have to
41 produce out 50 additional widgets. If you make widgets for skis, you may make
42 20 widgets every month during the summer even though you don’t sell any, just
43 so that you have enough in the war
