Part of Earth's beauty comes from its oceans. Ocean scientists study the chemical make-up of the ocean, weather patterns, the geography of the ocean floor, and many other areas. Their work is exciting, although sometimes dangerous. Using technology to do certain tasks helps. For example, robotic arms are used for very dangerous tasks.
One basic part of ocean study is understanding waves and how they work. Wind is the great maker of waves. The waves we know are mostly produced by winds blowing over the sea. They are directly connected with the wind speed and the time that wind lasts.
Sometimes ocean life can be seen in the wave. Living things seem to be staying within the wave, moving slowly inside it as if they were weightless. Besides the beauty of waves, scientists are interested in their technical ways. The diagram of waves shows how scientists examine waves. Waves are measured (测量) from the top (crest) to the bottom (trough). This allows scientists to find out the height of a wave. They also measure waves from crest to crest to determine (测定) the length of a wave.
During serious storms, huge waves might cut a sea ship apart. Ships are at great risk of winding up as broken pieces after being hit by the force of a huge wave. By understanding the ocean, scientists can prevent this breakup of ships by predicting when the water will be too dangerous for people and their ships. The study of waves and the ocean also allows scientists to make sure how certain beaches were formed. By studying the oceans, a great deal can be learned about the surface we live on.
1.Why are robotic arms used? Because ________.

What covers three-fourths of the Earth's surface? It's the water that makes up the Earth's four oceans. They are the Pacific, the Atlantic, the Indian and the Arctic. The Pacific Ocean is the largest and deepest. The Arctic is the smallest and shallowest.
Stand on a beach and watch the ocean. You will see that it is never still (平静的). The ocean is in constant motion (运动). Wind blows across the surface of the water. This makes waves. Ocean waves are different in height. A light wind causes small waves. In a hurricane (飓风), winds can cause huge. dangerous waves that can get to be more than 14 meters high!
Ocean currents (洋流) are lots of water that move from seaside to seaside. Like waves,currents are caused by wind. Ocean currents can be warm or cold. In areas close to land, warm ocean currents make the air warmer; cold ocean currents make it colder.
At high tide (涨潮时期), the ocean covers much of the beach. At low tide, you can walk on the sand that had earlier been covered by ocean water. Tides are caused by the pull of gravity (重力)as the moon circles the Earth.
The ocean provides people with many resources. Ocean water has salt. a basic cooking material. Ocean fishing provides work and food for many people. The ocean is also a fun place to visit. Children who live near the ocean often like to swim in the waves. hunt for shells. and play in the sand.

The environmental group Greenpeace reported that plastic and chemical pollution are often found in snow and seawater collected in Antarctica(南极). Greenpeace collected water and snow samples(样本)from Antarctica during a visit this year. Laboratory tests proved the effect of human on the Antarctic.
"It was about one microplastic piece at least per liter(升). It's worth worrying." said Greenpeace's Louisa Casson. Microplastics are extremely small parts of plastics. They come from the breakdown of bottles and other plastic waste in the world's oceans. In addition to microplastics, the Greenpeace study also proved that the presence of other chemicals and some harmful matter. These chemicals are widely used in industrial production and affect the birth and development of wildlife.
Plastic has been shown to harm wildlife. An example of this happened in southern Thailand. That was when a pilot whale died after eating up 80 pieces of plastic waste. Tests illustrated the waste weighed about eight kilograms.
International care about plastic pollution is rising. In India, Prime Minister Modi recently promised to ban all single-use plastic by 2022. In the city of Mumbai, Bollywood movie stars have been taking part in waste clean-up activities at Versova beach.
Plastic has been found in every corner of the world's oceans, from the bottom of the Pacific Mariana Trench to Antarctica. World governments decide on a European Union advice to create an Antarctic Ocean Protection Zone. At 1.8 million square kilometers, the area will be the largest protected one on the Earth.
1.Greenpeace collected water and snow samples showing_______________.
A.the currents never play a role of protection
B.human has an effect on the Antarctic
C.more people have come to the Antarctic

Everybody knows that Earth spins from west to east. That is to say, it appears to be turning counterclockwise (逆时针) rapidly when viewed from above the North Pole. But what if Earth started spinning the other way?
Scientists from Germany have made a computer simulation in which Earth spins in the opposite direction ﹣ clockwise when viewed from above the North Pole. This showed them some interesting things about the weather and geography on Earth, Live Science reported.
As Earth spins in a counterclockwise direction, it shapes certain ocean currents (洋流). The direction of ocean currents, together with winds, produces different weathers around the globe. But a backward spin changes the ocean currents and winds. ▲ Western areas of the lands on Earth cool down as the eastern parts warm up. Winters become even colder in northwestern Europe, while eastern Russia becomes warmer than before. Rain no longer falls on the planet's wettest places.
Another result of a backward spin is that Earth becomes greener. Scientists found that global desert (沙漠) areas reduce from 42 million square kilometers to 31 million square kilometers. This may have something to do with the changing weather. Therefore, you can see rich green landscapes from Central Africa to the Middle East, which are mostly covered with deserts now. More surprisingly, the Sahara Desert becomes an oasis.
However, deserts don't disappear. They just appear in some places in which they never appeared before. Deserts would cover North America, where countries like the United States and Canada lie. Sand dunes would replace the Amazon rainforest in South America.
A backward spin would keep the main features (特征) of Earth's geography, such as the size, shapes and positions of lands and oceans. But it would change the interactions between circulating air, ocean and geography, lead scientist Florian Ziemen told Live Science.
1.What would a backward spin bring to Earth?
A.The direction of ocean currents and winds would be different.
B.Rain would no longer fall on western areas of the lands on Earth.
C.Deserts would become larger and cover the planet's wettest places.
D.The size, shapes and positions of lands and oceans would be changed.
2.Which of the following sentences can be put in the blank of Paragraph 3?
A.Anyway, deserts cover the planet.
B.Therefore, the weather is different.
C.However, the positions of oceans changes.
D.Surprisingly, the area of lands is larger.
3.The underlined word "oasis" in Paragraph 4 means ________ in Chinese.
A.海洋 B.绿洲 C.戈壁 D.高原
4.The passage is most probably taken from a magazine on ________.
A.history B.culture C.art D.geography

Thirteen years ago, the Planet Earth wildlife documentary took us all on an amazing journey. We went from deep rainforests to the bottom of the ocean. Now a new one ,Our Planet, will let us see different animals and the influence of humans on the natural world. The documentary covers 50 countries and areas. It took more than four years to produce it.
With the latest 4K video technology, the show allows people a wonderful new look at nature. “People are given a chance to better get themselves into the lives of the animals” said Fothergill, one of the show's producers.

Seventy percent of our planet is covered by one huge body of seawater-the ocean. In 2008, the United Nations recognized(确立) June 8 as World Oceans Day. It's a day to think about the important role that the oceans play in our lives, the dangers that our oceans are facing and the action we can take to protect them.
The ocean is home to the most of plants and animals on Earth. Plants in the sea provide us with 70 percent of O2 we breathe. The ocean controls our climate (气候), providing heat in winter and cool air in summer. It also provides us with food and medicine. No matter where you live on the planet, no matter how far from the sea, your life is dependent on the ocean.
The biggest problem facing the ocean at the moment is plastic pollution. Reducing single-use plastic, including plastic bags and plastic bottles, has been an important theme for World Oceans Day for a number of years.
Climate change and rising sea temperatures are also a huge problem. Rising sea temperatures have a direct influence on weather patterns and are seen as partly responsible for an increase in extreme (极端的) weather.
The day is celebrated in all kinds of ways, including special events on the beach, river clean-ups, school activities, art contests and film festivals. You can join in to remind people about the importance of our oceans and to make a difference.
1.What percent of our planet is covered with seawater?
A.30% B.40% C.70%
