21、It has been found in South Australia that a worm-like creature about the size of a grain of rice is the oldest ancestor on the family tree that includes humans and most animals. The creature lived about 535 million years ago. It is considered to be an evolutionary step forward for early life on Earth.
Researchers have been working hard to find evidence of the common ancestor of most animals. Developing its body structure and organization successfully allowed life to move in specific, purposeful directions. This includes everything from worms and dinosaurs to amphibians(两栖动物) and humans. But for our common ancestor, they knew that fossils(化石) of the tiny, simple creatures they imagined would be nearly impossible to find because of its size and soft body. Then, they turned to fossilized burrows(动物洞穴), dated to the Ediacaran Period, found in South Australia.
For 15 years, scientists knew the burrows were created by the creature. There was no evidence of what made the burrows and lived in them until researchers decided to take a closer look at the burrows. Geology professor Mary Droser spotted impressions shaped like ovals(椭圆形) near the burrows.
A 3-D laser scan revealed the impressions containing evidence of a body shaped and sized like a rice grain, with a noticeable head and tail which suggested it had muscles. The muscles would have enabled the creature to move and create the burrows, like the way a worm moves. And the size of the creature matched with the size of the burrows they found.
【1】What does the underlined word “It” mean in the first paragraph?
A．A family tree.
B．A grain of rice.
C．A worm-like creature.
D．An evolutionary step.
【2】What did the researchers do during the study?
A．They developed the creature in the expected way.
B．They studied a large number of worms and dinosaurs.
C．They observed the burrows close up.
D．They went back to the Ediacaran Period some years ago.
【3】What inspired the scientists to explore the origin of the burrows?
A．3-D laser scan.
B．The impressions.
C．Some good ovals.
D．More burrows.
【4】What does the text mainly tell us?
A．The researchers worked very hard in the burrow.
B．The worm-like creature may be animals’ ancestor.
C．It is very difficult to name a new kind of creature.
D．Australian people like fossils of many creatures.
22、Phil Wise’s heart raced as he opened one of the transport tubes. He and a team of scientists stepped back as a young Tasmanian devil(袋獾) named Oddity came out. Oddity took a cautious look around and then ran into the forest on Maria Island.
Wise is a wildlife biologist from the Save the Tasmanian Devil Program. The scientists working with this program study Tasmanian devils, monitor their health, and track the devils found in the wild. Because a rare disease is reducing the number of devils, Oddity and 14 others were raised on a preserve and then brought to Maria Island to be released into the wild.
Though they are raised in zoos all over the world, devils live wild only in Tasmania. They are important to the ecosystem because they eat dead animals they find, which helps clean up the environment. But a cancer called Devil Facial Tumor Disease (DFTD) is killing devils on mainland Tasmania, endangering the species. The goal of the scientists who released Oddity and the others was to create a population of disease-free Tasmanian devils on Maria Island. Oddity is a part of this “insurance population” of devils raised in zoos and wildlife preserves.
The scientists chose Maria Island for the release because there is no DFTD there. It is separated from mainland Tasmania by the ocean. Devils from the rest of Tasmania can’t get there, which prevents the facial disease from spreading.
Wise and his fellow scientists monitored Oddity and the 14 other Tasmanian devils. The animals did so well that 13 more devils were released. The 28 original Tasmanian devils have reproduced; there are now around 80 devils. Scientists are now figuring out their next move. According to Wise, the focus will soon shift to moving some of the healthy devils back to mainland Tasmania.
Wise says he is “extremely happy to know that animals are getting a chance to be free in the wild in an area that is free of DFTD. It is the ultimate aim of all who work to conserve threatened species.”
【1】Why did Wise and his team release the Tasmanian devils like Oddity?
A．To prevent DFTD killing them out.
B．To find out a treatment for DFTD.
C．To control the DFTD spread in zoos.
D．To protect Maria Island from DFTD.
【2】What probably made Maria Island chosen for the release?
A．Its wildlife diversity.
B．Its geographic location.
C．Its natural resources.
D．Its improved ecosystem.
【3】How was the released Tasmanian devils’ life?
A．Their safety was uncertain.
B．Their number was going up.
C．They hardly enjoyed freedom.
D．They recovered from DFTD.
【4】What does the text mainly talk about?
A．A program studying Tasmanian devils.
B．A disease threatening Tasmanian devils.
C．A measure to save Tasmanian devils.
D．A habitat of wild Tasmanian devils.
23、Shark attacks in the screen are amazing. That’s because your actual chances of ever being attacked by a shark are merely one in 11.5 million. That’s the same as your chances of winning an Oscar, which makes shark attack survivor, Mike Coots both incredibly unlucky and lucky: When Mike was 18, he lost his leg to a shark bite.
“I was attacked by a tiger shark in late October 1997. It was near my home on the island of Kauai — an autumn morning with friends. The waves were really good, so nothing was stopping us.” But then a large shark came right up under Mike and sank his teeth into Mike’s lower leg. As he tried to free himself, the shark bit down harder, shaking its head back and forth and threw Mike around like a rag(破布) doll. Mike did what he could do: He struck the shark in the face, again and again until the shark let him go. As Mike swam back into shore, he realized his lower right leg was gone. Witnesses who saw the terrible scene were shocked. Mike’s friends rushed to his aid, and sent him to the hospital.
When Mike recovered, he didn’t weep for his experience and instead he did what many of us might consider unthinkable: he started riding the waves again. In fact, his first time back was near the site of his attack. Meanwhile, he was curious — why was he attacked? His curiosity led him to research sharks and Mike did learn something essential that would change his life: Humans are far more dangerous to sharks than the other way around.
He began working with the Hawaii state government to help pass a ban on shark products. “I partnered with other like-minded shark attack survivors and biologists, and we headed to Washington to call on officials to create a nationwide law to protect sharks.”
【1】Why does the author show the chances of being attacked by sharks in the first paragraph?
A．To teach readers of some related knowledge.
B．To show Mike’s unusual experience of the shark attack.
C．To attract people to watch shark attacks in the screen.
D．To show everyone has the chance of winning an Oscar.
【2】How did Mike survive the shark attack?
A．By hitting the shark hard constantly.
B．By swimming to the shore as quickly as possible.
C．By shouting loudly for his friends’ help.
D．By shaking its head up and down to get away.
【3】What came to mind when Mike rode the waves again?
A．To overcome his fear of tiger sharks.
B．To research on how sharks attack humans.
C．To prove humans are more dangerous than sharks.
D．To find out the reason for his being attacked.
【4】Which of the following words can best describe Mike?
A．Humorous and kind.
B．Brave and kind-hearted.
C．Generous and honest.
D．Reliable and creative.
24、I'll admit I've never quite understood the obsession (难以破除的成见) surrounding genetically modified (GM) (改变) crops.To environmentalist opponents,GM foods are simply evil,an understudied,possibly harmful tool used by big agricultural businesses to control global seed markets and beat local farmers.They argue that GM foods have never delivered on their supposed promise,that money spent on GM crops would be better channeled to organic farming and that consumers should be protected with warning labels on any products that contain genetically modified ingredients.To supporters,GM crops are a key part of the effort to sustainably provide food to meet a growing global population.But more than that,supporters see the GM opposition of many environmentalists as fundamentally anti-science,no different than those who question the basics of man-made climate change.
For both sides,GM foods seem to act as a symbol: you're pro-agricultural business or anti-science.But science is exactly what we need more of when it comes to GM foods,which is why I was happy to see Nature devote a special series of articles to the GM food controversy.The conclusion: while GM crops haven’t yet realized their initial promise and have been dominated by agricultural businesses,there is reason to continue to use and develop them to help meet the enormous challenge of sustainably feeding a growing planet.
That doesn't mean GM crops are perfect,or a one-size-fits-all solution to global agriculture problems.But anything that can increase farming efficiency—the amount of crops we can produce per acre of land—will be extremely useful.GM crops can and almost certainly will be part of that suite of tools, but so will traditional plant breeding,improved soil and crop management—and perhaps most important of all,better storage and transport infrastructure (基础设施) especially in the developing world.(It doesn't do much good for farmers in places like sub-Saharan Africa to produce more food if they can't get it to hungry consumers.) I'd like to see more non-industry research done on GM crops—not just because we'd worry less about prejudice,but also because seed companies like Monsanto and Pioneer shouldn't be the only entities (实体) working to harness genetic modification.I'd like to see GM research on less commercial crops,like corn.I don't think it's vital to label GM ingredients in food,but I also wouldn't be against it—and industry would be smart to go along with labeling,just as a way of removing fears about the technology.
Most of all,though,I wish a tenth of the energy that's spent endlessly debating GM crops was focused on those more pressing challenges for global agriculture.There are much bigger battles to fight.
【1】How do environmentalist opponents view GM foods according to the passage?
A. They will eventually ruin agriculture and the environment.
B. They are used by big businesses to dominate agriculture.
C. They have proved potentially harmful to consumers' health.
D. They pose a big threat to current farming practice.
【2】What does the author say is vital to solving the controversy between the two sides of the debate?
A. Breaking the GM food monopoly (垄断). B. More friendly exchange of ideas.
C. Regulating GM food production. D. More scientific research on GM crops.
【3】What is the author's view on the solution to agricultural problems?
A. It has to depend more and more on GM technology.
B. It is vital to the sustainable development of human society.
C. GM crops should be allowed until better alternatives are found.
D. Whatever is useful to improve farming efficiency should be encouraged.
【4】What does the author think of the ongoing debate around GM crops?
A. It arises out of ignorance of and prejudice against new science.
B. It distracts the public attention from other key issues of the world.
C. Efforts spent on it should be turned to more urgent issues of agriculture.
D. Neither side is likely to give in until more convincing evidence is found.
