The oceans are unique to our planet. No other planet in our solar system has liquid water. The oceans cover about 70% of the earth's surface. They contain about 97% of the earth's water supply. Life on earth originated in the seas. The oceans continue to be home to an incredible number of plants and animals.

We know very little about the oceans. Because they are so deep and dark, they are hard to study. But scientists are discovering new strange creatures all the time. We are learning more by using satellites to look at the oceans' surfaces and by using buoys (航标) to measure temperature and saltiness. Special vehicles can now travel deep into the dark oceans to see what mysteries can be discovered.

More of the sun's heat is assimilated by water along the equator than at the poles. This means the water at the equator is warmer than water at the poles. These different water temperatures cause the water in the oceans to move. This is called an ocean current.

The air above ocean currents also moves. The warm or cold ocean air moves over the land as wind. Oceans are also a really important part of the water cycle. Evaporation (蒸发) from oceans creates most of the world's rainfall. Plants on land need the rain to absorb nutrients from the soil.

The oceans are also home to all kinds of sea life. These include fish, whales, dolphins, octopi, lobsters, crabs and shrimps. There are also jellyfish and starfish. Many kinds of plants, such as plankton, kelp and sea grass are part of the "forest of the seafloor."

Carbon dioxide in-oxygen out! Oceans help to capture and store carbon dioxide(C02). They are the largest natural "carbon sinks" in the world. Oceans trap about 1/4 of the CO2 that humans put into the air. Oceans also release oxygen. Half of the world's oxygen is produced by these tiny plants!

1.What does the author think of oceans?

A. They are amazing.　　 B. They are common.

C. They are boundless.　　 D. They are unimaginable.

【小题2 To know more about the mysterious oceans, ________.

A. scientists use satellites in the oceans

B. scientists are discovering new strange creatures

C. scientists are using satellites to monitor the depth of oceans

D. scientists are introducing scientific equipment in the research

The beautiful oceans that cover three-quarters of our planet are home to some of our most valuable natural resources. However, while our knowledge of outer space is quite wide, the same cannot be said about the deep waters, thanks to the fact that any attempts to monitor them have either been too awkward or too expensive. Now, California-based Liquid Robotics has come up with an invention that is both economical and easily used across the waters.

Called Wave Glides, the autonomous robot that resembles a surfboard consists of two interconnected sections - on the surface is a glider(滑翔机)fitted with solar panels, battery and sensors. Right below underwater is a navigation(航行) glider.

The robot travels at a snail’s pace gathering data. This data is quickly sorted by its solar-powered computer chips and then sent ashore for analysis. This robot contains no battery that needs recharging. It is a zero emission (排放)device that uses wave energy to push itself forward.

The company is working towards making the robot even more autonomous than it currently is. As it now stands, while the robot can sense a danger such as a ship or a shark, it does not have the ability to move away. Liquid Robotics wants to change that and program the robot so that it has the ability to move away from danger.

To encourage the general public to get involved with the informative data collected by Wave Glider, the company is planning to launch four of the robots on a yearlong trip across the Pacific. Two will head for Tokyo and two for Sydney. All the data they collect will be posted online and the person who comes up with the most innovative interpretation will be awarded a prize.

1.What can we infer from Paragraph 1?

A.It costs less to explore the sea than outer space. B.Outer space has more resources than the oceans

C.People do not have as much knowledge of oceans as space. D.Three quarters of natural resources come from the oceans.

2.What do we know about Wave Glider?

A.It is eco-friendly. B.It can be used as a surfboard.

C.It’s shaped like a snail. D.It uses solar energy to move.

3.What change is most likely to be expected of Wave Glider?

A.Traveling more quickly. B.Sensing danger autonomously.

C.Analyzing data underwater. D.Keeping itself away from danger.

4.Why will four robots be launched on a yearlong trip?

A.To find more natural resources. B.To collect data around the world.

C.To get people informed of collected data. D.To test their ability to work underwater.

5.What is the author’s purpose in writing the text?

A.To promote an online contest. B.To call on people to explore oceans.

C.To introduce a new invention. D.To share the data collected in oceans.

Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.

This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy literature or movies like The Lord of the Rings. This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?

Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife. Without modem technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction(交互) with the world around us, and sometimes even with our families and friends, we seek to understand and communicate with things that exist only in our imaginations or on a computer screen。

The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.

1.The popularity of The Lord of the Rings proves

A. the close connection between man and the fantasy world

B. the wonderful achievements of fantasy literature

C. the fine taste of moviegoers around the world

D. the general existence of the sense of curiosity

2.What can we infer from the underlined sentence in Paragraph 3?

A. People are far less familiar with the world of fantasy.

B. The world around us could serve as a source of wonder.

C. The world of fantasy can be mirrored by a small and lively pond.

D. Modern technology prevents us from developing our sense of wonder.

3. If our sense of wonder relies totally on the world of make-believe, we will

A. fail to appreciate the joy in our lives

B. be confused by the world of make-believe

C. miss the chance to recognize the fantasy world

D. be trapped by other worlds existing all around us

4. What is the main purpose of the passage?

A. To show us the hidden beauty in our world.

B. To warn us not to get lost in the fantasy world.

C. To argue against the misuse of the sense of wonder.

D. To discuss the influence of the world of make-believe.

To me, the ocean is our greatest wilderness. I love swimming in it , surfing its waves, watching it from shore and thinking about all the life living unseen under the surface.

When I take my little kids to check out tide pools, we’re overjoyed when we find a sea star or some shellfish. Lately, though, I've noticed a change in my favorite pools: there are more sea grasses and fewer animals with shells.

I can't help feeling these small changes portend something more troubling about our oceans. It matches what scientists are telling us: our oceans are being troubled by carbon dioxide that threatens corals, colorful fish, salmon, sea otters, even whales. Our oceans are facing a major change.

Every hour, a million tons of carbon dioxide from cars, factories and power plants rain down on the world’s oceans. Carbon pollution brings about a chemical reaction that turns sea water more acidic (酸的) and takes away things important for sea animals .

Some of us are already feeling the effects of this growing crisis（危机）. Shellfish farmers in the Pacific Northwest have reported a decrease in natural and farmed oysters(牡蛎). Just this week, a new studyproved the link between the huge reduction in the numbers of oysters and ocean acidification. As polar waters become more acidic, Alaskan fishermen are troubled by the future of smaller fish.

Without action, ocean acidification will have a disastrous influence on the food chain, affecting not only sea life but the people who depend on it for food and their living. Already, our oceans have become 30 percent more acidic since preindustrial times, and it gets worse every day. We can stop this frightening dream, but only if we act now.

That's why the Center for Biological Diversity has started a petition (请愿书) requesting President Obama and the Environmental Protection Agency to develop a plan to deal with ocean acidification. Decisive action can save sea life as we know it.

Now it isn’t too late to save our oceans and sea life. With immediate action to reduce carbon dioxide release we can start taking important steps today to deal with this disastrous situation. Join me in our petition calling for a national plan to save our oceans.

1.The author’s recent visits to the tide pool brought her ___ .

A．happiness         B．anger             C．concern          D．comfort

2.The underlined word “portend” in Paragraph 3 probably means ___ .

A．predict           B．prevent           C．replace           D．reduce

3.What the author worries about most is ____ .

A．the harm of sea grasses

B．carbon pollution in the sea

C．that the petition may be turned down

D．how fishermen can make a living in the future

4.What is the main purpose of the text ?

A．To inform.         B．To educate.        C．To persuade .       D．To instruct.

Whales live in the ocean, but they are not fish. They are warm-blooded mammals and must have air to breathe. The babies are born alive and drink milk from the mother's body. It took millions of years for the whale to develop as it is today.

Every spring groups of whales swim hundreds of kilometers to warm places to bear their young. Each group goes to the same place every year. The mothers take very good care of their babies. The fully grown whales are very gentle and playful with each other, and with humans. They “talk” to each other with a high noise that  sounds beautiful. This“talking” can be heard for more than 300 kilometers in open waters.

Yet humans kill over a hundred whales a day. They kill them to make whale oils and a lot of other things. Killing them is a modern business with modern machines and even harpoons( 鱼叉炮) that explode( 爆炸) inside the whales. A whale dies very slowly and in great pain. Some ships kill every whale they can find, even the mothers and babies. Then there are no young whales to grow up or to bear more young.

1.A commonly mistaken belief is that ____.

2.In the passage “mammals” refer to ____.

3.Every spring each group of whales ____.

4.When whales talk, it sounds like ____.

5.Every year humans kill ____ all over the world.

The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun’s family.

Two of them, Mercury (水星) and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity that holds them in their paths.

We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional (成比例的) to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed.

Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree.

1.There are ________ that travel around the sun in the sun’s family.

A．nine planets                           B．eight planets

C．one star and ten planets                  D．the earth and the sun

2.Which two planets make the longest trips around the sun among all the planets in the solar system?

A．Mercury and Venus.                     B．Neptune and Pluto.

C．Saturn and Uranus.                      D．Mars and Jupiter.

3.From the passage we can see__________

A．all the objects, big or small, must exert the same pull on one another

B．large objects exert the same pull on anybody as small objects

C．small objects exert the same on large ones

D．each object in the universe exerts a pull on all other objects

4.From the sentence “The pull between two bodies is proportional to the product of their masses.” We can infer that the pull between__________

A．the sun and the moon is greater than between the sun and the earth

B．the earth and the moon is greater than that between the sun and the earth

C．the sun and the earth is greater than that between the earth and the moon

D．the sun and the earth is the same as that between the earth and the moon
