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(前进 )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

Scientists know of more than 1,000 volcanoes on the surface of Venus, Earth’s “sister” planet. A big question has been: Are they still active? The scientists say yes.

Their evidence for recent volcanic activity on Venus comes from a lava (熔岩) flow in the planet’s northern hemisphere. The flow is hotter than the rocks around, which means the lava might still be cooling off. “The flow we studied seems to be very young---it is still warm inside,” Nataliya Bondarenko said.

Venus is a difficult planet to study from Earth because it is surrounded by thick clouds. Telescopes on Earth can’t see through these clouds, so the best information about Venus comes from spacecraft orbiting it.

Bondarenko and her colleagues studied the lava flow using data from NASA’s Magellan mission. That spacecraft spent four years in orbit around Venus and used radar to make a map of 98 percent of the planet’s surface. On October 11th, 1994, the mission ended, and the spacecraft plunged (跌落) through Venus’ heavy cloud cover and crashed onto the planet below.

While in orbit, the Magellan craft sent microwaves, which can go through Venus’ clouds, to the surface. Microwaves are invisible and can be as long as three feet. These waves are a kind of energy, like light. And like light, they bounce off surfaces. The way the waves bounced off the Venus’ surface and back to the craft supplied information that the scientists used to estimate the temperature of various parts of the planet’s surface. Bondarenko’s team found that the lava flow was hotter than its surroundings---which may mean the lava flow is in the process of cooling.

The scientists say the lava flow can’t be very old because if it were, it would have cooled off enough that Magellan wouldn’t have noticed the difference in microwaves. She adds that the flow appears in a 1978 view of the surface that a craft called the Pioneer Venus Orbiter captured.

1.What happened to Magellan in the end?

A. It was floating in space forever.

B. It flew into heavy clouds.

C. It returned to the Earth.

D. It fell onto Venus.

2.How could Bondarenko judge the temperature of the Venus?

A. By looking at it with a powerful telescope.

B. By measuring the thickness of clouds over Venus.

C. By calculating the microwave bouncing off Venus’s surface.

D. By orbiting Venus for 4 years in a spacecraft.

3.The best title for the passage may be “______ ”.

A. Warm lava on Venus

B. More volcanic eruptions on Venus

C. Venus is just like a big active volcano

D. Lava flows are first found on Venus

Floating on the surface of the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They move about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent (相等的东西) of the grasses that grow on dry land, and the comparison is an appropriate one. In potential food value, however, plankton far outweighs that of land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates(碳水化合物) each year, the sea’s plankton produces more than twice as much.

Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now scientists have at last begun to study this possibility, especially as the sea’s resources appear even more important as a means of feeding an expanding world population.

No one yet has seriously suggested that “planktonburgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among scientists.

One type of plankton that seems to have great harvest possibilities is a tiny creature called krill(磷虾). Growing to two or three inches long, krill are a major food source for the giant blue whale, the largest animal ever to live on the Earth. Realizing that this whale may grow 100 feet and weigh about 150 tons, it is not surprising that each one swallows more than one ton of krill daily.

Krill swim about just below the surface in huge schools sometimes wide, mainly in the cold Antarctic. Because of their pink color, they often appear as an entire reddish mass when viewed from a ship or from the air. Krill are very high in food value. If krill can feed such huge creatures as whales, many scientists reason, they must certainly be competitors among possible new food sources for humans.

1.Which of the following correctly describes plankton?

A. It has a higher food value than grasses. B. It is food for most small sea animals.

C. It can grow on dry land as well. D. It grows up in the deep water.

2.Why does the author mention”planktonburgers” in Paragraph 3?

A. To show scientists’ interest in plankton.

B. To describe the appearance of plankton.

C. To question the food potential of plankton.

D. To suggest plankton as a possible food source.

3.According to Paragraph 4, the blue whale___________.

A. feeds mainly on krill. B. can grow up to 150 feet.

C. suffers from lack of food. D. was born two or three inches long.

4.Which of the following is TURE about krill?

A. They mainly live in the Arcitc. B. They are of great value to humans.

C. They are the smallest sea animals. D. They come in many different colors.
