Language helps us communicate, express our thoughts, and share our feelings with other people. (Trước tiên, ngôn ngữ giúp chúng ta giao tiếp, diễn đạt suy nghĩ và chia sẻ cảm xúc với những người khác.)
We can hardly understand one another on a deep level. (Không có ngôn ngữ, chúng ta khó có thể hiểu được nhau theo chiều sâu.)
Secondly, most essential information about a nation is written in its own language. (Thứ hai là hầu hết các thông tin cần thiết về một quốc gia được viết sử dụng ngôn ngữ của nước đó.)
If we don’t master a language, it is hard for us to know its culture. (Do đó, nếu chúng ta không nắm vững một ngôn ngữ của một nước, chúng ta khó có thể hiểu được văn hóa của nước đó.)

A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometers in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the time it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word “radar”, in fact, gets its name from the term “radio detection and ranging”. “Ranging” is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots, radar is essential for air traffic control, tracking ships at sea, and for tracking weather systems and storms.
