Its on a river that connects two of the five Great Lakes. The Niagara Falls has two parts: the Horseshoe Falls on the Canadian side of the river, and th

11、e American Falls on the United States side. They are about 50 meters high, 1,240 meters wide.The Niagara Falls has three special falls. The tallest are the American and Bridal Veil falls on the American side. The falls are colourful lit up at night, and many people say theyre even more beautiful in

12、winter when the grounds are covered with snow and the waters turn to ice.Most visitors go as close to the falls as possible and watch the waters thundering down.The Niagara Falls is different from the waterfalls you find in mountains, where a thin stream of water comes down a mountainside, half-flyi

15、has two partsCThe American Falls get most waterDThe Niagara Falls is very beautifulBPart of Earths 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 someti

16、mes 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

17、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.

18、 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 wave

19、s 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

20、 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.6Why are robotic arms used? Because _.Acertain tasks are very dangerousBthe tasks are excitingCthe oceans are beautifulDthere are many

Scientists can decide the weather patterns. We cant find living things in the waves. By studying the ocean, scientists can p

23、revent the breakup of ships. The study of waves helps scientists know how certain beaches were formed.ABCD10Where is the passage probably from?AA diary entry.BA fairy tale.CA travel guide.DA science 四补全对话A：Hi，friends！Welcome to my town.Im your guide，Miss Lin.You can ask me anything.B：OK.1._A：Its ove
