听力原文: Peru is a country on the west coast of South America. It has five neighbor countries: Brazil, witch is situated to the east; Ecuador and Colombia which are to the north; and Bolivia and Chile, which are to the southeast. As I said, Peru is oil the west coast of the continent, so it has another neighbor: not another country, but the Pacific Ocean.
Peru is a large country. It's about one thousand three hundred kilometers long, and five hundred and sixty kilometers wide. Its land area is about one million two hundred and eighty five thousand square kilometers.
There are three main regions. First, there's the area along the coast, in the west; it's quite low, and it covers about ten percent of the whole country. Then there are the Andes Mountains. They run down the middle of Peru. They are very high, and they cover 25 percent of the country. Finally there are the forests and jungles of the east, covering the remaining 65 percent of the land.
As for the climate, it varies according to each region, so it can be divided into three. The western area near the coast has a dry climate. The central mountainous region, the Andes, is cool, with snow all the year on the highest peaks. The eastern forests are extremely wet, with an average rainfall of two hundred and fifty centimeters a year.

More Asians are jumping on a bicycle for fresh air and to lead a more environmentally-friendly and active lifestyle in recent years as staying sedentary inside a car for hours could take a toll on one’s health, and be hard on the wallet because of the high cost of fuel and maintenance.
听力原文: The wet winter that brought mud slides and record rains to the Southwest is now threatening spring flooding. The high snow pack in the mountains, combined with wet soils and high river levels, leaves the region susceptible to flooding.
