What does it look like? What kind of animals are living there? More than of the sea hasn’t been studied yet! Looking carefully at the deep sea is hard because it’s dark, cold, and the pressure is strong. Although there are challenges, scientists have still been able to research parts of the deep sea. One way is by using small tools called submersibles (潜水器). These tools record videos and collect samples of the water and seafloor. What scientists have found so far from their research is pretty amazing! The deep sea is home to animals that adapt (适应) to such dark and cold places in cool ways. Some animals have large eyes to take in light. Others are blind and smell things around to live. Many deep-sea animals can even make their own light. The female angler fish uses bacteria (细菌) to make light in order to catch food. Vents are another part of the deep sea we’re learning about. They are home to some small sea animals. Scientists are working to study more of the deep sea. In these dark, high-pressure places, they hardly find animals like fish or whales because their bodies would break into pieces under the strong water pressure. But each year they discover new kinds of sea animals. No matter what they discover next, one thing is sure — it will surprise us all! ( )1. How does the writer lead into the topic in Paragraph 1?

[B] Have large noses. [C] Smell things around. [D] Make their own fire. ( )3. What does the writer think of the future research on the deep sea? [A] It’s expensive to do it. [B] It’s too difficult to find animals. [C] It’s dangerous to take part in it. [D] It’s hopeful to find something new. ( )4. In which part of a magazine can we read the passage? [A] History. [B] Business. [C] Nature. [D]Culture. 七、任务型阅读（每小题2分，共10分） 阅读下面材料，从选项中所给的A—E五个选项中选出正确选项(其中一项是多余选项)，将其序号填入第 小题，并回答第5小题。 Bigfoot is one of the most famous mysteries of nature. People say it is a large, hairy creature (生物). It walks upright like a human, standing over 3 metres tall with wide shoulders. Its name comes from the huge footprints — up to 35 centimetres long. 1.________ Such stories have been told for hundreds of years, especially by Native American groups in North America. Over time, many people have reported seeing Bigfoot. Most sightings happened in faraway (遥远的) forests and mountain areas. Some people said they saw it. They described it as having thick, dark fur to stay warm in cold weather, and moving much faster than you might expect. 2. ________It stayed in the area after Bigfoot left. Some even said they heard deep growls (咆哮) or loud calls before catching a quick look at it. Scientists have different ideas about Bigfoot. Many think the reports are either mistakes or made-up stories. They say people might have seen bears or other large animals and thought they were Bigfoot. 3. ________They think it’s possible that scientists haven’t found this animal yet. 1. ________Whether it is real or not, Bigfoot remains something that makes people curious about nature’s secrets, encouraging us to learn more about the world around us. 选项： A. Others, though, think the stories might be true. B. Similar stories can also be found in other parts of the world. C. Many also talked about a strong, strange smell. D.
