难度321 词 数 It's thought that around 5 trillion pieces of plastic are currently floating in our oceans. Both mammals and fish benefit from the clean ocean. It is reported that more than 8 million tons of plastic end up in our oceans every year, and nearly half of the plastic we produce is single-use only. This shoe brand, however, is riding the wave of change and is on a mission to help clean up our waters and rid the sea of plastic bottles that can take up to 400 years to break down. Vivobarefoot's newest footwear uses recycled plastic materials and has created an education program that spreads awareness about how harmful plastic is for sea life. Every pair of shoes is made up of 17 plastic water bottles taken from the ocean and turned into a sustainable, comfortable pair of shoes, which are also healthy for your feet. And while not everyone can take part in ocean cleanups, choosing little ways we can give back to our planet goes a long way. Vivobarefoot's new products include a variety of high-performance styles such as casual sneakers, running shoes, and hiking boots. The brand hopes that its latest initiative(新方案) will help lessen the indifference to pollution and how harmful it is for all living beings. In the future, Vivobarefoot hopes to increase their production of shoes created from sustainable materials, and thankfully, it is now one of many brands that aim to increase environmentalism and educate communities on how global warming affects everyone. This year, they'll add more recyclable and traceable materials into more than half of their production line, and they have plenty of creative developments in the works as well. minimally wider, that concept the on Based benefit. health a have also shoes The

词 数 366 难度
In the wild, belugas, also known as white whales, are social animals. They swim in Arctic Ocean waters in groups. Highly intelligent, the whales use different sounds to communicate and find their way. Belugas are also among the smallest kinds of whales.
More than 210 belugas, including about 31 in the United States, live in aquariums and zoos around the world. The Georgia Aquarium has asked for permission to bring 18 more belugas into the United States. Since some whales had been captured off the coast of Russia, the National Oceanic and Atmospheric Administration(NOAA) was considering the aquarium's request. A law called the Marine Mammal Protection Act says the animals can only be brought into the country and put on display if they are captured without being hurt and there is an educational reason for doing so. Georgia Aquarium officials said another 18 belugas would help people learn more about the species and allow scientists to better understand how to protect it. The aquarium would also breed the whales so U．S. aquariums could continue to display them. “When we study and observe belugas, we can gain a better understanding of their biology and diseases that affect them, and learn how to aid populations in their natural habitats，” said William Hurley, Georgia Aquarium's chief zoological officer. “Much of this research would be impossible to do in the remote locations and extreme climates where the animals live.” The Georgia Aquarium would own 18 more belugas and would loan some to aquariums across the country. Some scientists including Lori Marino, a beluga whale expert at Emory University, in Atlanta, Georgia, felt strongly that the whales belonged to the ocean instead of tanks. These scientists said the whales are being used for entertainment rather than for education, and having them in aquariums was not necessary for the species to survive. “Captive belugas, like dolphins and other whales, do not do well in tanks; they belong to the oceans，” Marino suggested. “Not only is it unfair to the belugas but there is no educational value in putting captive dolphins and whales on display. Students learn about dolphins and whales best when they see and read about them in their natural habitats.”

Such noises are added to natural sounds. These sounds include the breakingof ice fields, underwater earthquakes, and sounds made by animals themselves.Decibels (分贝) measured in water are different from those measured on land. Anoise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.Some scientists have proposed setting a noise limit of one hundred and twentydecibels in the oceans. They have observed that noises at that level can frightenand confuse whales.A team of American and Canadian scientists discovered that louder noises canseriously injure some animals.The research team found that powerful underwater explosions were causing whalesin the area to lose their hearing. This seriously affected the whales' ability toexchange information and find their way. Some o f the whales even died. The explosions had caused their ears to bleed and become infected.Many researchers whose work depends on ocean sounds object to a limit of onehundred and twenty decibels. They say such a limit would mean an end to importantindustrial and scientific research.Scientists do not know how much and what kinds of noises are harmful to oceananimals. However, many scientists suspect that noise is a greater danger than theybelieved. They want to prevent noises from harming creatures in the ocean.16．According to the passage, which of the following is increasingly dangerousto sea creatures?A．The sound of cars.B．The sound of voices.C．Man-made noise pollution.D．The sound of steps.17．According to the passage, natural sounds include all of the following EXCEPT________．A．sounds made by animals themselvesB．ocean drillingC．underwater earthquakesD．the breaking of ice fields18．Which of the following is discussed in the third paragraph?A．The same noise level produces a different effect on land and in the ocean.B．Different places may have different types of noises.C．The decibel is not a suitable unit for measuring underwater noise.D．Different ocean animals may have different reactions to noises.19．Which of the following is true of whales?A．They won't be confused by noises.B．They are deaf to noises.C．Their ability to reproduce will be lowered by high-level noises.D．Their hearing will be damage d by high-level noises.20．According to the passage, what will scientists most probably do in the future?A．They will work hard to reduce ocean noise pollution.B．They will protect animals from harmful noises.C．They will try to set a limit of 120 decibels.D．They will study the effect of ocean noise pollution.BThe sea has always interested man. From it we can get food, minerals, and treasure. For thousands of years, we could sail on it. But we could not go far beneath its surface. Man wants to explore deep into the sea. However，we are not fish. We must breatheair, so we can't stay under the water's surface for any length of time. To exploredeep water, man faces even more dangers and problems. A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases.He can wear a diving suit and have air pumped to him from above. He can carry a tankof air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body isunder great pressure. When a diver is under great pressure, his blood takes in someof the gases he breathes. As he rises to surface, the water pressure becomes less.If the diver rises too quickly, the gases in his blood form bubbles. The diver isthen suffering from the bends. The bends can cause a diver to double up in pain. They can even kill him.21．On the whole, this passage is about________.A．special mixtures of gases in deep seaB．the problems man faces in deep-sea divingC．air pressure under the surface of sea waterD．a kind of illness that man suffers in the sea22．A diver's body in deep water________.A．is under great pressureB．is just like that of a fishC．suffers from the bendsD．weighs very little23．The passage does not say so, but it makes you think that________. A．deep divers should be in good healthB．divers explore the deep sea only for treasureC．diving under the water too quickly causes a kind of illnessD．there is a special mixture of gases under the sea24．Why does a diver get the bends?A．He tries to do exercise under the water.B．His diving suit weighs too much.C．He comes to the surface too quickly.D．The air in his blood is used up.25．From the passage we can see that________.A．the sea began to interest man in the last few yearsB．man is not at home deep in the seaC．all divers will get the bends sooner or laterD．the air in the sea water will kill a diver if he is not careful答案课时作业(三十三)Ⅰ.1.A 前面的语境谈到：我儿子在学走路，故选A项。
