It’s a real case of fish out of water. Blennies (鲇鱼) in the South Pacific Ocean are gradually relocating to land to escape their predators (捕食者), in an example of evolution in action.
Fish first began crawling onto dry land about 400 million years ago, kicking off an evolutionary chain of events that led to humans. But their reasons for exiting the sea have been uncertain.
To look for clues, Terry Ord at the University of New South Wales in Australia has been studying several species of blennies at Rarotonga, the largest of the Cook Islands.
At low tide, blennies are commonly found swimming in rock pools around the edges of the island. But when high tide moves in, they climb up to dry land and move around the rocks until the tide retreats.
The researchers found that this is most likely to avoid predators that swim in with the rising tide – mainly bigger fish like lionfish.
To test what would happen if blennies did not have an escape plan, they made blenny models and sank them in the sea. The mimics ended up with wounds, bite marks and chunks-missing.
Of course, there are still dangers for blennies on land, like the occasional bird attack, but the predation risk on land is a third that of underwater.
What’s more, moving onto land has additional benefits for blennies. Holes in the rocks provide sheltered nests for laying eggs, and they can maintain their diet of bacteria.
In fact, several species of blenny fish at Rarotonga have already made the full transition to land-dwelling (陆生的) species. They continue to breathe with their gills, but have developed stronger tail fins and jump from rock to rock.
Ord believes that many evolutionary processes have been driven by the need to escape predators. “It is often assumed that animals move homes to find new sources of food, but in many cases, escaping predators is a stronger motivation.” he says.
1.Why do blennies climb to dry land when high tide comes?
A. To acquire better health. B. To search for more food.
C. To seek safer living conditions. D. To adapt to a new environment.
2.What does the underlined part “The mimics” in Paragraph 6 refer to?
A. The rocks in the water. B. The predators of blennies.
C. The researchers of blennies. D. The models of blennies.
3.What can be concluded from the last paragraph?
A. Ord’s research opens a new view.
B. Ord wonders why animals move homes.
C. Ord shows us the benefits of blennies’ evolution.
D. Ord has discovered how fish have become land dwellers.
4.Which of the following could be the best title for the text?
A. Blennies’ Living Habits
B. Why Blennies Choose to Live on Land
C. Blennies’ Evolutionary Process
D. How Blennies Escape from their Predators

Many of us would like to spend all of our time helping dogs in need, but it can be hard to carve out that kind of time. Well, one man, Eugene Bostick, decided that when he retired, he would devote the rest of his life to helping homeless dogs feel loved.
Eugene Bostick was fortunate enough to be able to retire at the ripe age of 65 after working his entire life on his farm. His farm was located at the end of a dead-end street, and he noticed that people would, unfortunately, abandon their dogs on the farm and race off.
Eugene refused to see these pets suffer, and he quickly picked up these abandoned dogs, giving them food and taking them to the vet to make sure they were spayed and neutered.
Eugene’s farm has all kinds of animals, such as horses and goats, so these dogs have plenty of other animals to play with.
Over the last 20 years, Eugene has shown his kindness by taking on these abandoned pets, but he also saw the chance to offer them a bit of adventure. After spotting a neighbor transporting rocks behind his tractor using barrels, he realized he could do the same for his dogs. Eugene got to work to make his own train, and made sure to add some pleasant pillows so his furry friends could travel in comfort. The dogs quickly got on the train, and together, they spent hours traveling around town and through the forests nearby.
After they were spotted around town, one neighbor took a picture of Eugene that went viral, and a GoFundMe page was started that gained plenty of donations. Eugene was amazed by everyone’s generosity, and was happy to see others help these abandoned animals feel loved. Eugene will continue to care for his dogs, and we should all follow his lead!
1.What can we learn from the passage?
A.Eugene wished to retire ahead of time to care for homeless dogs.
B.People would race to the farm to pick up homeless dogs.
C.Eugene and the vet took in many abandoned dogs together.
D.Eugene’s idea for the barrel train was inspired from his neighbor.
2.What’s people’s attitude to Eugene’s act?
A.Supportive. B.Unconcerned.
C.Doubtful. D.Astonished.
3.Which words can be used to describe Eugene?
A.Serious and hardworking. B.Caring and adventurous.
C.Rich and generous. D.Playful and Childish.
4.What can be the best title for this passage?
A.A retired man’s life B.Lucky dogs

"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you.?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said. Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. "Waves are one of nature's ways of picking up energy and then sending it off on a journey." When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine (涡轮机). The turbine can then power an electrical generator to produce electricity.
"The resource is huge," said Janet Swain of the World Watch Institute. "We will never run out of wave power." Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth's surface---that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic. Traditional sources of energy like oil and gas may someday run out. "Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!
1.The underlined phrase "picking up" is closest in meaning to ______.
A. starting again B. speeding up
C. improving D. gathering
2.We can make better use of wave energy if we ______.
A. shorten its journey to thousands of homes
B. build more small power stations on the oceans
C. reduce the cost of turning it into electric power
D. quicken the steps of producing electricity
3.It can be inferred that some day we might not worry about ______.
A. our power supply B. our boat traffic
C. air pollution D. our supply of sea fish

It is found that American students spend less than 15% of their time in school. While there’s no doubt that school is important, a number of recent studies reminds us that parents are even more so. A study published earlier this month by researchers at North Carolina State University, for example, finds that parental involvement — checking homework, attending school meetings and events, discussing school activities at home — has a more powerful influence on students’ academic performance than anything about the school the students attend. Another study, published in the Review of Economics and Statistics, reports that the effort put forth by parents (reading stories aloud, meeting with teachers) has a bigger impact on their children’s educational achievement than the effort devoted by either teachers or the students themselves. And a third study concludes that schools would have to increase their spending by more than $1,000 per pupil in order to achieve the same results that are gained with parental involvement.
So parents matter. But it is also revealed in researches that parents, of all backgrounds, don’t need to buy expensive educational toys or digital devices for their kids in order to give them an advantage. They don’t need to drive their offspring (子孙，后代)to enrichment classes or test-preparation courses. What they need to do with their children is much simpler: talk.
But not just any talk. Recent research has indicated exactly what kinds of talk at home encourage children’s success at school. For example, a study conducted by researchers at the UCLA School of Public Health and published in the journal Pediatrics found that two-way adult-child conversations were six times as potent in promoting language development as the ones in which the adult did all the talking. Engaging in this reciprocal（双向的) back-and-forth gives children a chance to try out language for themselves, and also gives them the sense that their thoughts and opinions matter.
The content of parents’ conversations with kids matters, too. Children who hear talk about counting and numbers at home start school with much more extensive mathematical knowledge, report researchers from the University of Chicago. While the conversations parents have with their children change as kids grow older, the effect of these exchanges on academic achievement remains strong. Research finds that parents play an important role in what is called “academic socialization” — setting expectations and making connections between current behavior and future goals. Engaging in these sorts of conversations has a greater impact on educational accomplishment.
1.Parents are even more important than schools because ______.
A. parental involvement makes up for what schools are not able to do
B. teachers and students themselves do not put in enough effort
C. parental involvement saves money for schools and the local government
D. students may well make greater achievements with parents' attention
2.It can be inferred from the 2nd paragraph that ______.
A. educational toys are unaffordable nowadays
B. digital devices can give children an advantage
C. some parents believe in enrichment classes
D. talking with children is a very simple task
3.The word "potent" is closest in meaning to ______.
A. powerful B. difficult C. necessary D. resistant
4.Which of the following will more encourage children's success at school according to the passage?
A. Parents order their children to stop playing video games.
B. Parents discuss with their children the possible future career.
C. Parents lecture their children on getting too low marks on tests.
D. Parents introduce colleges around the US to their children.
