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 singleuse 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.‎ The shoes also have a health benefit.

In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine, creating the largest floating barrier ever made.‎ The system, originally dreamt up by Mr. Slat, will be shipped out this summer to the Great Pacific Garbage Patch, between Hawaii and California, which contains estimated 1.8 trillion pieces of plastic. It will be the first ever attempt to tackle the patch since it was discovered in ‎ ‎1997.‎ Mr. Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea. “There were more bags than fish down there，” he recalls. Two years later he came up with a solution, quit university after six months and set up The Ocean Cleanup as a company. Mr. Slat says the first plastic to arrive on shore will be a major milestone. “We as humanity created this problem, so I think it’s also our responsibility to help solve it，” he says.‎ The Great Pacific Garbage Patch(GPGP) covers an area of 1.6 million square kilometers and contains at least 79，000 tons of plastic, research found last month. Most of it is made up of “ghost gear”—parts of abandoned and lost fishing gear, such as nets and ropes—often from illegal fishing vessels.‎ Ghost gear kills more than 100，000 whales, dolphins and seals each year, according to scientific surveys. Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic. Creatures eat plastic discarded in the sea thinking it’s food but then starve to death because they are not feeding properly. Others are trapped and die of starvation or are strangled or suffocated by ghost gear.‎ ‎【解题导语】　本文是一篇说明文，主要介绍了世界首个海洋垃圾清扫机的发明。‎ ‎1．What does the underlined word “detritus” in the second paragraph probably mean?‎ A．Waste.

That makes sense. All animals need sugar to live. It’s the fuel that powers our cells. So it’s not surprising that we’re born to want the sweet stuff.‎ Sugar stores the sun’s energy like a battery. After a meal, your body breaks down foods into their building blocks. It uses some sugar for energy right away. The rest get stored for the body to break down later. It’s a myth that sugar makes you extremely excited, but having a sugary snack can give you a quick burst of energy. That’s because the sugar in sweet foods is easy for your body to turn into fuel. When you eat other kinds of foods, like vegetables, it takes longer for your body to break the sugar down.‎ These days it’s easy to find sweet snacks. Sodas, candy, cakes and even foods that seem healthy, such as yogurt, can be packed with sugar. Food makers add sugar, because they know that to humans, sweet makes everything taste better. Americans eat about 20 teaspoons of extra sugar every day. That’s way more than what is good for us.‎ Eating too much sugar can cause more than a stomachache. It can make people overweight, decay the teeth and even cause diabetes. However, experts aren’t worried about naturally sweet foods—the problem is added sugar. So go ahead and enjoy sweet apples or even sugar—rich carrots that are also full of vitamins and other good stuff.‎ Even cake is great once in a while, as long as you don’t overdo it. After all, no one wants life to be dull. And your body needs its fuel!‎ ‎【解题导语】　本文是一篇说明文。糖能给人体提供必需的能量，且易分解，人天生需要糖分；虽然甜食尝起来可口，但是我们不要过多食用。‎ ‎5．The first two paragraphs are mainly developed by ________．‎ A．cause and effect B．problem and solution C．giving examples D．making comparisons A　解析：写作手法题。根据第一段尾句“So it’s not surprising that we’re born to want the sweet stuff.”和第二段倒数第二句“That’s because the sugar in sweet foods is easy for your body to turn into fuel.”，并结合第一、二段的内容可知，第一段解释了人天生需要糖的原因；第二段解释了甜食能快速补充能量的原因；据此可推知，第一、二段是通过解释因果的方法组织内容的，故A项正确。‎ ‎6．People may be tricked into eating too much sugar because ________．‎ A．no one wants life to be boring B．we’re born to want the sweet stuff C．socalled healthy food can be packed with sugar D．sugar is the fuel for the plants and animals on the earth C　解析：细节理解题。根据第三段第一、二句“These days it’s easy to find sweet snacks. Sodas, candy, cakes and even foods that seem healthy, such as yogurt, can be packed with sugar.”可知，甜食随处可见，即使是看起来健康的食品也会含有大量糖分，故人们会误食很多含糖食品。‎ ‎7．What does the author want to stress in Paragraph 4?‎ A．We’d better say no to sweet foods.‎ B．Experts are worried about added sugar.‎ C．Eating too much sugar is bad for our health.‎ D．We’d better consume sugar from natural sources.‎ D　解析：推理判断题。通读第四段可知，该段第一、二句介绍了食用过量的糖的害处；第三句说明专家对添加糖分的食品的担忧；第四句提出建议：吃富含糖但也富含维生素和其他有益成分的天然食物。据此可推知，该段旨在强调，我们最好食用天然食物来摄入糖分，故D项正确。‎ ‎8．Which of the following can be a suitable title for the text?‎ A．Sugar Is Everywhere B．Sugar Brings Happiness C．Why Do We Love Sugar?‎ D．Why Does Sugar Make Us Fat?‎ C　解析：标题归纳题。通读全文可知，糖能给人体提供必需的能量，且易分解，人天生需要糖分；虽然甜食尝起来可口，但是食用过量的糖有害人体健康，我们最好食用不但富含糖分、还含有维生素和其他有益成分的天然食物。故C项最适合作本文标题。‎ Ⅱ.七选五 ‎(2020·滁州模拟)Whoever wrote the song “It’s the Most Wonderful Time of the Year” must have never experienced the holiday blues. Fortunately, psychological research suggests some effective ways you can use to beat the holiday blues. The key point is that sadness and other tough emotions are not what we should try to avoid. 1.________. Here are four strategies to help you make your own happiness recipe this holiday season.‎ Don’t force cheer At family gatherings with cousins you secretly can’t stand, you tend to put on a happy face. Indeed, that might even seem like the most mature response—no drama, no conflict. But a 2011 study followed dozens of bus drivers, looking to see when they gave forced or honest smiles at their passengers. The results showed when the drivers pretended to have a good mood, their actual moods got worse. 2.________．‎ Let out sadness The results of the busdriver study can be explained by researchers, who find that negative feelings like sadness or anger only increase when we try to control them. 3.________.
