The ocean is always moving：waves break on the surface, sea levels rise and fall with the tides, and currents flow below the surface. Although it looks as if the water in a wave is moving across the surface of the ocean, it is not. The water is actually moving up and down. This is why an object on top of a wave will bob up and down, but not move forward.

When a wave reaches the shore, however, the water does move forward. It surges(前進 )onto the shore. This is because the “bottom” of the wave drags on the sand and the “top” continues on, crashing onto the shore. This crashing water is called the surf. Most waves are caused by wind blowing across the ocean's surface. The size of a wave depends on how fast and how far the wind blows over the surface and on the depth of the wave. Small winds can cause ripples, while strong winds create large hurricane waves.

Along most shorelines. water levels rise and fall twice a day. These changes, called tides. are caused by the gravitational pull of the Sun and the Moon. The ocean surface lifts, or bulges(凸出), in two places: on the side of Earth that faces the Moon and on the side of Earth that faces away from the Moon. Both bulges cause a high tide on nearby shorelines. At the same time that the high tides occur, low tides occur between the two bulges.

Tides are also affected by the pull of the Sun, although the effect of the Sun is not as great as the effect of the Moon. When the Moon and Sun are lined up with Earth, the combined pull is the strongest, causing the highest high tides and the lowest low tides. These very high and very low tides are called spring tides. Weaker tides, called neap tides, happen when the Moon and the Sun are at right angles to Earth. High tides alternate with low tides. Along most shorelines, a high tide or low tide occurs about every six hours.

1.The word “alternate” in the last paragraph means .

A. appear suddenly

B. bob up and down

C. change or become quickly

D. happen or follow one after another

2.The best title for the passage is .

A. The Moving Ocean B. Tides and Waves

C. Ocean and Earth D. Waves and Currents

There are many people who say Thomas Edison invented the twentieth century. Although there are those who may disagree, yet Edison was one of the greatest inventors in America.

Born in 1847 in Ohio, Thomas Edison attended school for only three months. After his teacher said that he could not learn, Edison’s mother decided to teach him at home. There he was allowed to study the subjects that most interested him. By age ten, Edison had built a science laboratory of his own.

Edison got his first job at age twelve on the railway selling candy and newspapers. There he once saved a boy whose father was the boss of the railway station. In return the boss helped him a lot.

In his late twenties, Edison built an “invention factory” where he and his business partners could devote all their time to inventing. After improving upon the telephone, Edison created the phonograph(留聲機). Although Edison did not actually invent the light bulb, he did create an electric lighting system which led to its widespread use.

Edison set up the first central electric power station in 1882, so New York became the first city in the world to have electric lights. This was the beginning of the modern world in which electricity became a way of life.

The following year, one of Edison’s engineers discovered electrons(電子), which at last led to electronics. Without electronics, we might not have radio, TV, computers, or space travel. The rest of Edison’s life was spent making and improving inventions.

Thomas Edison died at the age of eighty-four in 1931. Three days later, much of America dimmed(使暗淡) its lights in honor of the inventor—a man who had more impact (影響)on the development of present-day civilization than anyone else in history.

1. The passage tells us that ________.

A. Edison didn’t like to study at school

B. Edison invented the light bulb in his late twenties

C. even without electronics, we might have radio, TV, computers, or space travel

D. New York was the first city in the world to have electric lights

2.From the passage, we can infer that _________.

A. Edison’s teacher thought Edison was not worth teaching

B. Edison’s mother stopped Edison studying at school

C. Edison didn’t invent many things in all his life

D. Edison didn’t spend his life working on these inventions when he was old

3.Why did many Americans dim their lights when Edison died? ________.

A. Americans wanted to save more energy.

B. Americans were used to dimming their lights.

C. Americans dimmed their lights in memory of the great inventor.

D. Americans were made to dim their lights.

4.The best title for this passage is ________.

A. Edison, a Poor Man

B. Edison, a Great Inventor

C. Edison Died at 84

D. Edison and His Childhood
