Meet the longest-living vertebrate（脊椎动物）in the world, the Greenland shark.
Found primarily in the very cold waters of the North Atlantic, these slow-swimming sharks can be as big as the largest great whites, reaching up to 21 feet in length. They're among the largest of carnivorous（食肉的）fish, and yet grow perhaps only a centimeter or so a year. Such slow growth yet big size is usually an indicator of a long-lived animal.
“We only expected that the sharks might be very old,” Julius Nielsen, at the University of Copenhagen in Denmark, told NPR in 2016. “But we did not know in advance. And it was, of course, a very big surprise to learn that it was actually the oldest vertebrate animal.”
Imagine being 150 years old before you're ready to have your first child! Imagine being born before the United States was even a reality. For humans-who rarely make it to a century mark—it's difficult to fully understand.
Little is known about Greenland sharks, even basics such as where they give birth or how many of them there are, though researchers at a July 2017 conference at the University of Exeter thought that they may mate in “hidden” Arctic fjords. No one has even witnessed one hunting, though they have been found to have various vertebrate ones in their stomachs such as polar bear, seals, fast-swimming fish and even moose etc.
Given the shark's incredibly long lifespans, scientists are diving into the sea creature's genome, looking for clues. That conference also highlighted the work being done to separate the shark's longevity gene, with complete DNA information gathered from almost 100 sharks, including some born in the 1750s. Finding such a gene could go a long way in explaining why some vertebrates, like humans, have such limited lifespans.
These sharks also serve as swimming history books. Their tissue, bones and DNA could tell us a great deal about the waters of the world from a time before the Industrial Revolution, large-scale commercial fishing and the pronounced ocean pollution we see today.
Check out what it's like to swim with one in this encounter with what is a small and young—and yet to us, still fairly old—Greenland shark.
1.What can we know about Greenland sharks from the first two paragraphs?
A.Longest-living, and slow-swimming carnivorous vertebrate.
B.Longest-living, and slowest-swimming vertebrate.
C.Largest, but fast-growing carnivorous vertebrate.
D.Longest-living, largest carnivorous vertebrate but fast-growing.

C.Greenland shark can live more than one hundred years.
D.Greenland shark is really the oldest vertebrate in the world.
3.What kind of animals do Greenland sharks prefer?

The bristlecone pine is the longest-living thing on the earth. These trees, with their strangely-shaped, wind-beaten limbs(枝干), can live up to 5,000 years. But experts worry that a warming climate in some areas may threaten its future.
Researchers say warmer weather is permitting a similar kind of tree, the limber pine, to take over good growing places from the ancient bristlecone. They say the tree is being crowded out of mountainous areas where it grows.
“The bristlecone pine is the oldest individually growing organism,” researchers say. They grow in high mountain forests in eastern California, Nevada and Utah. In those mountains, the trees face high winds and extreme temperatures, which leave them with twisted limbs and shapes. “Even in such tough conditions,” Brian Smithers, a researcher at the University of California, said, “the limber pine is taking all the good spots.”
The limber pine is the bristlecone’s distant relative and competitor. It can also live a long time——up to 2,000 years. And it is usually found at lower altitudes, where temperatures are warmer. However, according to a three-year study which centered on trees that have started growing in the last 50 years in California’s White Mountains, most of the trees growing at higher altitudes were limber pines.
Scientists compared the competing species to two o1d men in a very slow race up a mountainside. This race between such slow-growing trees takes thousands of years. They say climate change is causing the competition.
Smithers said the bristlecone pines are not in danger of disappearing. But he assumes they could be crowded out of some places where they have grown for thousands of years.
The researchers say the findings show how climate change can affect the two kinds of trees. The information, they say, can help scientists understand more complex forests.
1.What’s the function of Paragraph 1?
A. To introduce a topic. B. To summarize the whole passage.
C. To describe the appearance of a tree. D. To praise the hard work of the experts.
2.What does the underlined sentence in Paragraph 2 mean?
A. There will be older trees sent out of those mountains.
B. There will be more places covered with bristlecone pines.
C. There will be better limber pines replacing the ancient ones.
D. There will be fewer bristlecone pines growing in those areas.
3.According to the passage, the reason why limber pines can grow at higher altitudes is_________.
A. the high winds B. the difficult conditions
C. the changing climate D. the extreme temperatures
4.What is the researchers’ attitude towards the future of the bristlecone pine?
A. Positive. B. Concerned.
C. Enthusiastic. D. Indifferent.

The world is filled with smart, talented, educated and gifted people. We meet them every day. A few days ago, my car was not running well. I pulled it into a garage and the young mechanic had it fixed in just a few minutes. He knew what was wrong by simply listening to the engine. I was amazed. The sad truth is that great talent is not enough.
I am constantly shocked at how little talented people earn. I heard the other day that less than 5 percent of Americans earn more than $100,000 a year. A business consultant who specializes in the medical trade was telling me how many doctors and dentists struggle financially. It was this business consultant who gave me the phrase, “They are one skill away from great wealth.”
There is an old saying that goes, "Job means 'just over broke（破产）’".And unfortunately, I would say that the saying applies to millions of people.Because schools do not think financial intelligence is intelligence, most workers "live within their means".They work and they pay the bills.Instead I recommend to young people to seek work for what they will learn, more than what they will earn.
When I ask the classes I teach, “How many of you can cook a better hamburger than McDonald's?” ,almost all the students raise their hands. I then ask, “So if most of you can cook a better hamburger, how come McDonald's makes more money than you?” The answer is obvious: McDonald's is excellent at business systems. The world is filled with talented poor people. They focus on perfecting their skills at building a better hamburger rather than the skills of selling and delivering the hamburger.
1.The author mentions the mechanic in the first paragraph to show that__________.
A. he is just one of the talented people B. he is ready to help others
C. he has a sharp sense of hearing D. he knows little about car repairing
2.The underlined part in the third paragraph can be best replaced by__________.
A. spend more than they can afford B. do in their own way
C. live in their own circle D. live within what they earn
3.Why do talented people earn so little according to the author?
A. They don’t work hard enough B. They lack financial intelligence.
C. They don't make full use of their talents D. They have no specialized skills.
4.The main purpose of the author is to tell us __________.
A. how young people can find a satisfactory job B. What schools should teach about finance
C. why so many talented people are poor D. how McDonald's makes much money
