泽熙美文Reading Comprehension
Some people associate migration mainly with birds. Birds do travel vast distances, but mammals also migrate. An example is the caribou, reindeer that graze on the grassy slopes of northern Canada. When the weather turns cold, they travel south until spring. Their tracks are so well-worn that they are clearly visible from the air. Another migrating mammal is the Alaska fur seal. These seals breed only in the Pribilot Islands in the Bering Sea. The young are born in June and by September are strong enough to go with their mothers on a journey of over 3,000 miles. Together they swim down the Pacific Coast of North America. The females and young travel as far as southern California. The males do not journey so far. They swim only to the Gulf of Alaska. In the spring, males and females all return to the islands, and there the cycle begins again. Whales are among the greatest migrators of all. The humpback and blue whales migrate thousands of miles each year from the polar seas to the tropics. Whales eat huge quantities of plankton. These are most abundant in cold polar waters. In winter, the whales move to warm waters to breed and give birth to their young.

The Sense of Humor
Biologically, there is only one quality which distinguishes us from animals: the ability to laugh. In a universe which appears to be utterly devoid of humor, we enjoy this supreme luxury. And it is a luxury, for unlike any other bodily process, laughter does not seem to serve a biologically useful purpose. In a divide world, laughter is a unifying force. Human beings oppose each other on a great many issues. Nations may disagree about systems of government and human relations may be plagued by ideological factions and political camps, but we all share the ability to laugh. And laughter, in turn, depends on that most complex and subtle of all human qualities: a sense of humor. Certain comic stereotypes have a universal appeal. This can best be seen from the world-wide popularity of Charlie Chaplin’s early films. The little man at odds with society never fails to amuse no matter which country we come from. As that great commentator on human affairs, Dr. Samuel Johnson, once remarked, ‘Men have been wise
