Greek soldiers sent messages by turning their shields (盾) toward the sun. The flashes reflected light could be seen several miles away. The enemy did not know what the flashes meant, but other Greek soldiers could understand the messages.

Roman soldiers in some places built long rows of signal towers. When they had a message to send, the soldiers shouted it from tower to tower. If there were enough towers and enough soldiers with loud voices, important news could be sent quickly over distance.

In Africa, people learned to send messages by beating on a series of large drums (鼓). Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple, they could be sent at great speed for hundreds of miles.

In the eighteenth century, a French engineer found a new way to send short messages. In this way, a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet. It was like spelling out words with flags and arms.

Over a long period of time, people sent messages by all these different ways. However, not until the telephone was invented in America in the nineteenth century could people send speech sounds over a great distance in just a few seconds.

According to this passage, the Roman way of communication depended very much upon______.

A．fine weather

B．high tower

C．the spelling system

D．arm movements

During the second half of 1776, the British had driven Washington's armies from their stro

ngholds in and near New York City. Washington retreated, moving southeast across New Jersey.

Before his army reached the shores of the Delaware, he sent soldiers ahead to bring together all the boats they could find. When the British arrived at the east bank early in December, the Colonials were safely across. And the British could find only two small boats on a pond.

For the time being, the British gave up the chase. They set up camp at Trenton and at other strongholds along the Delaware.

Washington had the boats on the Pennsylvania side, but that was about all he had. Food was short, and many soldiers were too iii to march. And any day now, the river might freeze, making it possible for the British force to cross into Pennsylvania.

If the struggle for freedom was to continue, Washington had to have a victory. Finally he decided to re-cross the Delaware at Mckonkey's Ferry. That was nine miles up river from Trenton. Washington's plan was to cross under cover of darkness on Christmas night and attack the 2,000 to 3,000 British soldiers in Trenton. The general expected that the enemy force would still be celebrating the holiday. On the evening of December 25, Washington gave the orders to cross. It was sleeting snowing, and the river was filled with floating ice. Finally, his force of more than 2,000 men was on the Jersey side. It was after 2 a.m.. In a battle that lasted less than two hours, they defeated the enemy force. Washington had the victory he needed.

This story is about______.

A．the battle for human rights and progress

B．the battle of Delaware River

C．the American Civil War

D．the American War of Independence

Some surveys show that a lot of people believe that the glare from snow causes snow-blindn

ess. Yet, wearing dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of "snow light".

The United States Army has now determined that glare from snow actually does not cause snow-blindness in troops in snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of a wide snow-covered territory. His gaze, in consequence, continually shifts and jumps back and forth over the entire landscape in search of something he can look at. Finding nothing to focus on, hour after hour, the eyes never stop searching, and the eyeballs will become sore and eye muscles will ache. Nature reduces this uncomfortable feeling by producing more and more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision becomes increasingly unclear. The result may be total, even though temporary, snow-blindness.

Experiments led the Army to a simple method of overcoming this problem. A small group of soldiers will be sent ahead of a main body of troops. They are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even these soldiers themselves throw lightweight, dark colored objects ahead, on which they, too, can focus. The men following them can then see something. Their gaze is arrested. Their eyes focus on a bush and, having found something to see, stop searching the snow-blanketed landscape. By focusing their attention on lone object at a time, the troops can cross the snow-covered wilderness without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white territory is overcome.

Dark glasses have proved to be ______ in overcoming headaches, watering eyes and blindness caused by the glare from snow.

A．useless

B．useful

C．available

D．fruitless

The Cherokee Nation

Long before the white man came to America, the land belonged to the American Indian nations. The nation of the Cherokees lived in what is now the southeastern part of the United States.

After the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing was to the white man. He decided to invent a way to write down the spoken Cherokee language. He began by making word pictures. For each word he drew a picture. But that proved impossible -there were just too many words. Then he took the 85 sounds that made up the language. Using his own imagination and an English spelling book, Sequoyah invented a sign for each sound. His alphabet proved amazingly easy to learn. Before long, many Cherokees knew how to read and write in their own language. By 1828, they were even printing their own newspaper.

In 1830, the U.S. Congress passed a law. It allowed the government to remove Indians from their lands. The Cherokees refused to go. They had lived on their lands for centuries. It belonged to them. Why should they go to a strange land far beyond the Mississippi River？

The army was sent to drive the Cherokees out. Soldiers surrounded their villages and marched them at gunpoint into the western territory. The sick, the old and the small children went in carts, along with their belongings. The rest of the people marched on foot or rode on horseback. It was November, yet many of them still wore their summer clothes. Cold and hungry, the Cherokees were quickly exhausted by the hardships of the journey. Many dropped dead and were buried by the roadside. When the last group arrived in their new home in March 1839, more than 4,000 had been died. It was indeed a march of death.

The Cherokee Nation used to live ______.

A．on the American continent

B．in the southeastern part of the US

C．beyond the Mississippi River

D．in the western territory

The American Revolution was a citizens revolution. Ordinary men took a large part in it. O

ne of them was Paul Revere, a silver worker. He lived in Boston many years ago during the time when many people in the British colonies in America felt that they were being used for Britains gain. They felt that they were being taxed without fair representation in the British government. The people of Boston were especially angry, and additional British troops had been sent there to keep the excited colonists under control. Paul Revere was one of those who believed that the British would soon be on the march against the villages and farms near Boston. On the night of the eighteenth of April, 1775, Revere rowed across the Charles River to a place opposite Boston where his saddled horse was ready to ride. If the British soldiers came, he was to ride to warn the people. A friend in Boston was hidden near the British troops in a place where he could watch what they did. If they marched by land, he was to hang one lantern (灯笼) high in the tower of the old North Church in Boston where Paul could see it. If they came by sea, he would hang up two lanterns. Toward morning Revere saw two lights in the tower. The British must be coming by sea! He jumped on his horse and rode through the countryside before dawn in order to warn the farmers and villagers that they must fight at the daybreak. He rode all night and in the morning, by the time the troops arrived, the farmers were hidden all along the roads with their guns loaded. When the British came, the Americans drove them back. These first battles of the American Revolution were fought at Concord and at Lexington, Massachusetts, on April 19, 1775. In 1776 the colonies signed a declaration of independence.

What is the authors main purpose in the passage？

A．To provide information about the childhood of Paul Revere.

B．To discuss the war between the British and the Americans.

C．To tell the reader a story about Paul Revere in the American Revolution.

D．To describe the courage of the farmers and villagers in the American Revolution.
