All mail arriving in Massachusetts colony was sent to the home of an appointed official in Boston. In turn, he would deliver the mail from Boston on horseback to its destination, receiving one penny for each good article of mail. Later in the century postal services were established between Philadephia and Delaware. In 1691, the British crown appointed the first postmaster general to have charge of the mail for all the colonies in North America. Later, Benjamin Franklin served as the postmaster by the newly formed United States government.Franklin was responsible for establishing the Unite States postal system on a permanent basis. He increased the number of post offices, introduced the use of stagecoaches to carry mail, and started a package service system. Later in the 19th century, as railroad and steam boats appeared, they were used to carry mail into the towns.Some communities, especially those out west, were far from the services of transportation. To serve them, the post offices developed a system called “star routes”. Private contractors were paid to deliver mail to the communities from horse and wagon.The postal service, which started over three centuries ago, had developed into an extensive government service with post offices in every city, town, and villages in the United States.86.What is the subject of the passage?A. The U.S. postal system. B. The history of the U. S mailC. A history of Benjamin Franklin. D. Letter writing 87. When was the first North American postal service started? A. Two centuries ago B. Over 300 years agoC. In 1691 D. In the 16th century 88. For what did Benjamin Franklin deserve credit? A. He was the first postmaster general in North America. B. He established a government postal service for Britain. C. He served both British and American government. D. He governs the postal system in the U.S 89.Why were “star routes” started? A. Because the horse and wagon were slow in carrying mails. B. Because the trains were too fast. C. Because transportation was difficult for some towns. D. Because the communities didn’t like ordinary post offices. 90. What eventually happened to the postal service?A. It failed to serve the people in remote places.B. It developed a transport systemC. It remained the same as it started many years before.D. It developed all over the country.Under proper conditions, sound waves will be reflected from a hillside or other such obstruction. Sound travels at the rate of about one-fifth of a mile per second. If the hill is eleven hundred feet away, it takes two seconds for the sound to travel to the hill and back. Thus, by timing the interval between a sound and its reflection(the echo), you van estimate the distance to an obstruction.During World War II the British used a practical application of this principle to detect German planes on their way to bomb London long before the enemy was near the target. They used radio waves instead of sound waves, since radio waves can penetrate fog and clouds. The outnumbered Royal Air Force (RAF) always seemed to the puzzled Germans to be lying in wait at the right time and never to be surprised. It was radio echoes more than anything else that won the Battle of Britain.Since the radio weaves were used to tell the direction in which to send the RAF planes and the distance to send them (their range of flight, in other words), the device was called radio detecting and ranging, and from the initials the word radar was coined.81. Sound waves reflected from a hill can be used to estimate the_______.A. intensity of sound B. distance to the hillC. speed of sound D. height of the hill82. Which of the following can be resulted from by practical application of this principle?A. a radio directing and ranging device. B. an electronic detecting device C. new electronic instruments for planes D. new radio sets for RAF bombers83. Radar enabled the English to_____ A. confuse German bomber pilots B. direct the outnumbered RAF planes effectivelyC. detect German planes on their way to London. D. both A and B84. Why did the British use radio waves?A. Because they were more exact than sound waves.B. Because they could not be detected.C. Because they were easier to use than sound waves.D. Because they could penetrate fog and clouds.85. What can you infer from the passage?A. Radar was a practical application of a well-known principle.B. Light waves could be used in a device similar to radar.C. Radar greatly increased the effectiveness of the REAF.D. Sound waves are reflected from a hillside under all conditions.
