Ⅰ.阅读理解

A

(2019·昆明调研)When she was found off the coast of California four years ago，the fur seal，known as Ziggy Star，was skinny and fragile.She was unfit to return to the wild.And though a professional rescue team took her in to care for her，Ziggy continued to decline.“I wouldn't have given her next week，”says Uriarte，a surgeon who led a recent first-of-its-kind brain operation on the seal.

The operation was the first of its kind to treat hydrocephalus in fur seals.The surgical team at Tufts was unable to find any documented evidence of a similar procedure，so they needed a lot of preparation to operate on Ziggy's brain.The biggest concern in operating on Ziggy was how to control the animal's anesthesia(麻醉)．“When they're under anesthesia their body's reaction includes decreasing their heart rate，blood pressure，and breathing，”says Flower，who observes Ziggy and the other animals' care，describing the special challenges of operating on seals.On the day of the surgery，Flower says that she and her team“were all quite anxious not knowing what would happen”．Moving quickly was extremely important；the longer she was under anesthesia，the more likely that she could lose her breathing，says the surgeon.The seal has been kept on land to prevent water from entering the cut on her head.

Now，Ziggy is eating a full diet and is beginning to gain weight again.“Recently I've allowed her to go swimming，”says Flower.However，the source of Ziggy's neurological disorder(神经紊乱) is still a mystery.“My theory is that when she was found，she had a head injury，”Uriarte says.“Hit by a boat maybe...That happens a lot with seals.”Flower is less willing to guess.“I don't think there's enough information to make that assumption.We just don't know what happened to her.”

【语篇解读】 本文是动物保护类记叙文。Ziggy Star是一只在加利福尼亚海岸被发现的非常瘦弱的海豹，因为Ziggy有脑积水，医生为她进行了手术，她现在已经能够正常进食，体重也在逐步恢复，但究竟是什么导致了她的神经紊乱，这依旧是一个谜。

1．When first found，Ziggy Star looked .

A．thin and weak B．active and excited C．bloody and fierce D．strong and energetic

A [细节理解题。根据第一段第一句“When she was found off the coast of California four years ago，the fur seal，known as Ziggy Star，was skinny and fragile”中的skinny(极瘦的)和fragile(虚弱的)可知A项正确。]

2．What was the most challenging task on the day of the operation? A．Helping the seal regain her breathing. B．Using anesthesia properly on the seal. C．Making full preparations for the operation. D．Balancing the functions of the seal's organs.

B [细节理解题。题干中的关键词是the most challenging task(最有挑战性的任务)，据此定位到第二段中的“The biggest concern in operating on Ziggy was how to control the animal's anesthesia(麻醉)”，由此可知，手术最大的挑战是如何控制麻醉，所以选B。]

3．What can we learn about Ziggy after the operation? A．She is strong enough to live in the wild. B．She is suffering from a heart rate disorder. C．She has already become as heavy as before. D．She is recovering from the brain operation.

D [推理判断题。题干的关键词是after the operation，据此定位到文章最后一段第一句“Now，Ziggy is eating a full diet and is beginning to gain weight again”，由此可知，手术后，海豹已经能够正常进食，体重也在恢复，所以选D。]

4．What is probably the author's purpose in writing the text? A．To show humans' love for a creature. B．To find out a way to operate on a seal. C．To remember an injured seal in danger. D．To explore the reasons for a seal's injury.

(2019·陕西省部分学校检测)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 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“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.

【语篇解读】 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。 5．What does the underlined word in the second paragraph probably mean? A．Waste. C．System.

B．Ocean. D．Machine.

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—often from illegal fishing vessels”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. C．Giant tubes.

B．Dolphins and seals. D．Abandoned fishing gear.

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.

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.

B [主旨大意题。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。]
