7、ize activitiesBThe first thing you notice at Nate Ottos house is a 1967 Oldsmobile 98, an old car. Inside is a small, 100-year-old reed organ (簧风琴). Its just a small taste of whats in Ottos house: self-playing, old-style musical robots called player pianos. Some sound and look as good as they did a
8、century ago. Some are awaiting repair. Otto, a 29-year-old, has decided that its his job to bring player pianos back to life.As the owner of Rum River Restoration, Otto believes hes the only full-time player piano restorer (修复师) in the state of Minnesota. He specializes in Jazz Age objects that once
9、 wereubiquitousin America but now are largely forgotten except by collectors.Otto believes in doing things the old-fashioned way and tries his best to make player piano restorations as real as possible.Otto views the player pianos that he fixes as kinetic art (动态艺术) pieces. The classic player piano,
10、 or pianola, was first developed at the end of the 19th century. It was seen as a thing that helped to change American musical tastes, spreading new styles of music such as jazz to middle-class people. In their successful days, most of the pianos made in the U.S. were player pianos.By the 1920s, how
11、ever, the rise of radios and record players provided an even easier way to listen to music, hurting the sales of player pianos. The market for the instruments finally disappeared with the 1929 stock market crash (股票市场暴跌) and the Great Depression.Keeping a player piano going today is a little like re
12、storing an old car: It takes time, love, money and so on. A full rebuild of a player piano mechanism might take 100 to 150 hours of work and cost $5,000 to $8,000 on average, Otto said. But its worth it for some people to once again hear an instrument that brought generations of family members toget
13、her to listen, sing and dance.24. What does the underlined word “ubiquitous” in Paragraph 2 mean?A. Natural.B. Difficult.C. Common. D. Interesting.25. What do we know about the classic player piano?A. It was created in the 20th century.B. It was invented by Ottos family.C. It helped the spread of ja
14、zz.D. It can be easily found today.26. How was the player piano in the 1920s?A. It fell out of popularity.B. It was not known to the public.C. It was first brought outside the U.S.D. It caused the sales of record players to fall.27. What did Otto think of restoring player pianos?A. It was a waste of
15、 time.B. It was worth continuing.C. It was easier than restoring cars.D. It was not helpful in supporting his life.CIt is the dry season in a Kenyan national park. A small group of poachers (偷猎者) walk along a dried-up riverbed, planning to kill a black rhino (犀牛). The men are hidden by underbrush on
16、 the riverbanks. But they are seen by a poaching alarm system developed by the Zoological Society of London (ZSL). Their guns and knives set off the Instant Detect systems hidden metal detector (探测器), which causes a camera hidden in the forest to start working. The images travel by radio to a base s
17、tation and then via a satellite (卫星) to the parks control center. Soon rangers are sent off to catch the poachers.Similar situations will soon be playing out in wildlife parks around the world, as animal protection bodies have changed their views on high-tech methods to save animals. These groups we
18、re slow to see the effective use of new monitoring (监控) tools, but with the aid of groups such as Google, they are now welcoming the devices warmly as a way to stop poaching.ZSL began to develop detection technology around six years ago, working with tech companies including Google and Iridium. ZSLs
19、 Instant Detect will be soon ready for use in the field. Other conservation bodies are also developing similar systems.Conservation organizations jumped in because they saw a chance to make a difference with a camera trap a digital camera that takes pictures of creatures in the wild. Scientists have
20、 used camera traps to photograph animals for many years. But until recently these had no wireless connection. Their users had to physically visit each one to remove its SD card, which was often full of useless images.ZSL tested the first version of the system by watching Antarctic penguins, Canadian
21、 bears, Australian night parrots, and Kenyan elephants and rhinos. But it suffered from communication problems. The team has developed a better version, Instant Detect 2.0. It has had successful tests in Africa. And it will have more tests in Thailands Western Forest Complex and elsewhere before it
22、is put to use.28. What does the first paragraph mainly describe?A. How serious poaching in Kenya is.B. How rangers in Kenya protect wildlife.C. How wildlife survives in the dry season.D. How a new poaching alarm system works.29.What are conservation organizations attitudes to ZSLs Instant Detect?A.
23、They pay little attention to it. B. They feel doubtful about it.C. They are happy to accept it.D. They are amazed at it.30. What can we learn about the camera traps of the past in Paragraph 4?A. Their major disadvantages.B. Their many different uses.C. Their recent development. D. Their great perfor
24、mance.31. What do we know about ZSLs Instant Detect 2.0?A. It can be carried easily by rangers.B. It causes communication problems.C. It has been designed mainly to save rhinos.D. It will not be widely used without more testing.DIt was a large fish market northwest of Mumbai. Shark fins were sent on
25、to tables. Tens of millions of sharks are killed for the fin trade every year, and a quarter of the worlds sharks, rays, and ghost sharks are in danger. The international trade in many species is not allowed, but it can be nearly impossible for wildlife officials to tell whether the fins here are fr
26、om protected species.The samples could be sent to a lab for DNA testing, but the test would take a full day. But Shaili Johri, a post doctoral biology researcher at San Diego State University, had a handheld device, or tool, that can say what species a part belongs to in a short time, using only a s
27、mall tissue (组织) sample. The gene sequencing (基因序列测定) done by the MinION device, which she was testing out at the fish market, is a promising new tool to help fight the illegal shark fin trade.Johri with another author recently published a study in the journalScientific Reportsexplaining the first u
28、se of the new device for keeping sharks and other wild animals safe from attacks. The smartphone-sized device is made by UK-based Oxford Nanopore Technologies. It has been used for the recognition of Ebola virus, among others. It is also likely to help prevent wildlife crime.It requires a small tiss
29、ue sample and a laptop. It can tell a species in three or four hours. But it has one downside: the tool costs $1,000, including two original cartridges (测试盒). Every following sequencing cartridge, which can do 12 samples at once, costs an extra $500. Thats roughly $42 per sample. The traditional DNA
30、 analysis method costs as little as $5 a sample.Hollie Booth, a sharks and rays advisor, says the MinION could have lots of practical uses, including controlling wildlife trade across countries or illegal fishing in markets. And the possibilities of this device arent just limited to sharks. These to
31、ols could be used to recognize elephant ivory, pangolin scales, and various other wildlife.32.What did Johri use the MinION for at the fish market?A. Collecting tissue from endangered fish.B. Discovering sharks gene sequences.C. Recognizing the species of a shark.D. Saving sharks losing their fins.3
32、3.What does the new study mainly tell us about the MinION?A. How it can help reduce wildlife crime.B. Its use for wildlife protection purposes.C. How it was developed by a UK company.D. Its influence on different scientific fields.34. What is a disadvantage of the MinION?A. It makes mistakes at time
33、s. B. It requires more time.C. It is hard to use. D. It is expensive.35.What does Booth probably think of the MinION?A. It will save many kinds of animals.B. It should be used after further research.C. It must make technological improvements.D. It needs more support from wildlife officials.第二节（共5小题；

H
35、owever, the state of care for the whales has not changed, so that now the species is in danger of extinction.The change follows the sad news about the death of a right whale calf (崽).37According to the National Oceanic and Atmospheric Administration (NOAA), the calf was killed by a vessel (船只) strik
36、e in New Jersey.IUCN updates its Red List of threatened species every year. According to the organization, a scientific study now shows that the right whales are dying out because of humans.38Although these right whales were listed as endangered species before, they have continued to be killed by hu
37、man actions. IUCN now hopes that by listing the whales as critically endangered, more work will be done toward their protection.39Besides, more than 10 right whales were reported as having serious injuries. Such a large number of dead and injured whales brought a sharp focus on the decreasing popula
