After all, it can cost a large amount of money to have this kind of holiday experience. So tour operators try ‎ to place eager swimmers as near as possible to the dolphins by trying to predict where the dolphins will be.‎ Research has shown that while dolphins can move away if they do not want to interact (交流) with human swimmers, they do not like it at all if the swimmers slip into the water directly on top of them or if humans are in their path of travel. However, if swimmers enter the water to one side of them, the dolphins do not avoid the swimmers to the same extent.‎ In all cases, the dolphins seem to have become more sensitive to the presence of the swimmers. For dolphins, swimming amongst or with humans is not necessarily a high priority. This research has shown that only 19% of any group of dolphins will participate in interaction. Young dolphins are the most likely to interact; they do seem curious about being with humans. It is believed that they see humans as “entertainment” and that the interaction is a new and unusual experience for them.‎ It is frequently asked whether “swimwithdolphins” tourism should be discontinued. The advice is that dolphins should be given enough periods of time throughout the day when they are not exposed to tourism. Permitted interactions should not be too disturbing to the dolphins since there could be mothers and calves (幼崽) present in dolphin groups. There should also be educational campaigns about the creatures and what is likely to cause danger to them.‎ It is not easy to explain to someone that they cannot fulfill their lifelong dreams because the dolphins are resting, or a mother dolphin and her calf are in the area. But if we are to enjoy these remarkable animals and not just use them for our entertainment, then we must carefully monitor the “swimwithdolphins” industry worldwide.‎ 语篇解读： 本文主要讲述了通过研究发现人类所进行的“和海豚一起游泳”的活动会对海豚产生影响。所以作者呼吁要对“swimwithdolphins”活动进行监督，否则会对海豚造成伤害。‎ ‎1．What makes “swimwithdolphins” tourism popular?‎ A．The local government's encouragement.‎ B．The improvement of people's living standard.‎ C．The increasing number of tourists.‎ D．The high profits of the industry.‎ 解析：选B　细节理解题。根据第一段第一句“The‘swimwithdolphins’ tourist industry is becoming more popular every year with the increase of people's income.”可知，这一产业的兴盛是由于人们收入的增加，生活水平的提高，故B项正确。‎ ‎2．Why are young dolphins more likely to swim with humans?‎ A．They do this out of curiosity.‎ B．They like humans better.‎ C．They are less sensitive.‎ D．They prefer new things by nature.‎ 解析：选A　细节理解题。根据第三段的最后两句可知，小海豚喜欢和人互动是因为它们对人类表现出好奇，故A项正确。‎ ‎3．What does the author suggest the “swimwithdolphins” industry do in Paragraph 4?‎ A．Make people know the hidden threat to dolphins.‎ B．Strictly limit the expansion of the industry.‎ C．Avoid interaction with young dolphins.‎ D．Expose dolphins to tourists only in the daytime.‎ 解析：选A　推理判断题。根据第四段中的“The advice is that dolphins should be given enough periods of time ... There should also be educational campaigns ...”可知，作者建议人们了解这一产业活动可能对海豚造成的潜在影响和威胁，故A项正确。‎ ‎4．What is the author's attitude to “swimwithdolphins”？‎ A．Negative.　　　　　　　 B．Cautious.‎ C．Supportive. D．Optimistic.‎ 解析：选B　观点态度题。根据最后一段中的“But if we are to enjoy these remarkable animals and not just use them for our entertainment, then we must carefully monitor the ‘swimwithdolphins’ industry worldwide.”并结合全文内容可知，作者建议要监督“和海豚一起游泳”这一产业，否则会对海豚带来伤害，由此判断出作者对这一产业的态度是“谨慎的”，故B项正确。‎ B ‎(2019·陕西部分高中摸底考试)Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic.‎ The experts believe the machine should be able to collect half of the detritus in the patch — about 40,000 metric tons — within five years. 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 f or 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.‎ ‎5．What does the underlined word in the second paragraph probably mean?‎ A．Waste. B．Ocean.‎ C．System. D．Machine.‎ 解析：选A　词义猜测题。根据第二段画线词前的“collect half of”和第四段第一句中的“first saw for himself the amount of plastic polluting the sea”和第五段最后一句中的“parts of abandoned and lost fishing gear, such as nets and ropes”可推知，画线词的意思是“垃圾”。故选A。‎ ‎6．Which one makes up most of the garbage in Pacific from the passage?‎ A．Fishing vessels. B．Dolphins and seals.‎ C．Giant tubes. D．Abandoned fishing gear.‎ 解析：选D　细节理解题。根据第五段最后一句“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”可知，太平洋里的大部分垃圾是由废弃的钓鱼用具组成的。‎ ‎7．Why do some creatures in The Great Pacific Garbage Patch die of starvation?‎ A．Because they are killed by ghost gear.‎ B．Because they are suffocated by ghost gear.‎ C．Because they don't like eating plastic.‎ D．Because they are not feeding properly.‎ 解析：选D　细节理解题。根据最后一段倒数第二句中的“but then starve to death because they are not feeding properly”‎ 可知，大太平洋垃圾带的一些生物死于饥饿是因为它们不能真正地进食。‎ ‎8．What is the main idea of the passage?‎ A．A report about the death of marine life.‎ B．News about the first machine to clean up ocean plastic.‎ C．Information about ocean plastic.‎ D．The reason for inventing a machine.‎ 解析：选B　主旨大意题。通读全文可知，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。第一段“Scientists are preparing to launch the world's first machine to clean up the planet's largest mass of ocean plastic”点明了文章的主题。故选B。‎ Ⅱ.完形填空 The mysterious golden box was tied with ribbon and sat upon a shelf in the dining room.During my childhood, I would often __1__ where it had come from and why it was never __2__.Sometimes, I would climb upon a chair to get a __3__ look, but would never __4__ it for fear I would __5__ something special.Many years passed as the box continued to sit with its __6__ contents, undisturbed.‎ The tragic __7__ of my father happened one spring day.After my father's funeral, my mother carefully __8__ the ribbon and opened the treasured box with __9__ in her eyes and a lifetime memory in her heart.On a yellow piece of paper were written these words: “My love, I will go __10__， but I will hold dear my love for you, so I leave you this box filled with kisses.Please wait till I return.”‎ Then my mother told me this story: My parents met on a blind date when in college.
