High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of 250 km/hr and existing lines in excess of 200 km/hr are widely considered to be high-speed, with some extending the definition to include much lower speeds (e.g. 160 km/hr) in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design.

Many countries have developed high-speed rail to connect major cities, including Austria , Belgium, China, France, Germany, Italy, Japan, Poland, Portugal, Russia, South Korea, Sweden, Taiwan, turkey, United Kingdom, United States and Uzbekistan. Only in Europe does HSR cross international borders. China has 16,000 km of HSR, accounting for 60 percent of the world’s total. While high-speed rail is usually designed for passenger travel, some high-speed systems also offer freight service.

Passage Two

Only one animal can walk 200 miles without stopping once to rest. It would take a person two days and two nights to walk this far, and only one man has ever done it without stopping. What amazing animal has such endurance？ The camel! The camel is well known for something else, too. It can cross an entire desert without a single drink of water. Its body is built in a special way to help it store water and food.

A person has just one stomach, but a camel has quite a few. Within each stomach are layers and layers of cells. These cells are like tiny water balloons, storing liquids until the camel needs them. When the camel drinks, the cells grow larger and larger. For a whole week, they can keep the animal's thirst away by sending water to all parts of its body.

And did you ever wonder why the camel has a hump？ The hump is a storage place for fat. Because it has this storage area, the camel does not need to eat very often. When the animal needs energy, the layers of fat serve as fuel to keep it going on the long, hot days in the burning sun.

The camel has one other gift that makes it well suited to arid regions. This gift is its amazing nose. A camel can smell a water hole from miles away!

When a camel moves it sways from side to side like a ship on a wavy ocean. Because of this swaying motion, the camel has been called the "Ship of the Desert."
