On Saturday morning I along with 15 or so others, boarded a fishing boat. But we weren’t out for the fish. We were looking for seabirds.

“We’ll see a Cook’s petrel (黑脚圆尾鹱) today,” I predicted? feeling confident. Not that I had a good reason to be： only one Cook’s petrel has ever been officially recorded in these waters.

Twenty minutes later, a Cook’s petrel came just as I expected. Thrilled at its sudden appearance, we hurried to take photos and lowered our voice for fear that the bird should be frightened away. Within a minute, the bird was gone. It turned out to be one of the few highlights of an otherwise surprisingly quiet day, but I live for moments like this. For a few hours, I was in my happy place.

Along with music, birds have been what I am crazy about. It started when 1 was eight. Memories get vague here, and possibly unreliable, but the first flash was a chance sighting of a kingfisher (翠鸟) on the Ovens river, a few meters from where my father actually was fishing. My interest in birds was aroused.

For me, watching birds-or birding, to use the more active verb—was and still is an escape and a harbor. Earlier this year, a study by University of Exeter found that it was associated with lower levels of anxiety and depression, conditions with which I am unfortunately all too familiar.

And yes, I’m a bird lover. I once flew to Perth to see Australia’s second red-legged water bind, only to find it had been eaten by a cat. That’s birding—things don’t always happen on cue like that Cook’s petrel. But it s not about the numbers. Whether it’s on my block or out to sea, I prefer to think that I don’t find the birds; they find me: in that happy place.

Watching the beautiful fireworks is a joyful experience. However, over ten million blind Americans and more around the globe have never been able to experience this joy. Fortunately, Feeling Fireworks or tactile (触觉的) fireworks invented by the scientists in .Switzerland may change that soon.

To experience the show, users stand in front of a large, 2.9 by 2.9 feet, flexible screen, which is made of a special material. They then place their hands at the base of the screen and move them around to feel the fireworks. Alternatively, their hands can be situated in the center of the screen, where the initial explosions happen, and then moved across to explore other fireworks.

As the fireworks begin to explode, one of five nozzles (喷嘴) at the back of the screen starts to spray water, creating “a beautiful fireworks show”. One specializes in the “blooming flower effect”, while another reproduces the “crackle” effect. The rest take care of-rockets and explosions. A computer controls the timing, while a camera tracks the person’s movement. According to the inventors, Feeling Fireworks

B. As usual.

D. An accidental sight of

B.

His

father’s

D. Now and then.

allows users to experience “tactile fireworks that are similar to physical fireworks happening in the sky”.

A screen displaying the vivid images created by the water jets makes the tactile experience fun for everyone. Paul Beardsley, who led the research team, says, “We want ail blind, visually damaged, and sighted people to try Feeling Fireworks, and to depart with a shared and enjoyable memory of a fireworks evening.”

First shown at the User Interface Software and Technology conference held in Canada, the low-cost technology is still in its early stage, with only a 66 percent success rate. However, the team plans to continue improving the experience and believes the day when everyone will be able to enjoy the thrill of fireworks shows is not far.

28. What does the underlined word “that” in Paragraph 1 refer to? A. The blind can’t watch the beautiful fireworks. B. The blind can’t feel the explosion of fireworks. C. The blind can’t get as much joy as normal people. D. The blind can’t experience the joy of watching fireworks.

29. Where can people first feel the explosions of fireworks on the screen? ‘ A. At the top.

B. On the side.

C. In the middle.

D. At the bottom.

30. What does the third paragraph mainly tell us about Feeling Fireworks? A. Its principles. C. Its instructions.

B. Its invention progress.

D. Its explosion effects.

31. What is the advantage of Feeling Fireworks? A. It is cheap to produce. B. Its success rate is very high. C. Sighted people can also enjoy it.

D. People can experience the effects at home.

To save as much language diversity as possible in the face of its rapidly dying out, researchers suggest using “evolutionary trees”, a tool from conservation

biology.

One of the world’s 7,000 languages disappears every other week, and half might not survive the 21st century, experts say.

When setting conservation goals, ecologists use evolutionary trees-diagrams that show how biological species (物种) are related to one another—to identify species that have few close relatives. Such species are said to be evolutionarily distinct. Similarly, recent advances in the construction of language trees make it possible to measure how unique a language is.

“Evolutionary trees have transformed our understanding of how life has evolved and helped us to decide which species most need conserving,” says Jonathan Davies, senior author of the new study.

“The rapid rate of language loss, as well as limited resources for preservation, means that we must choose carefully where to focus our efforts,” adds Max Farrell, a PhD student in Davies’ lab. “The more isolated (孤立的) a language in its family tree, the more unique information it contains and eventually contributes to language diversity.”

As a case study? they used this approach to rank 350 Austronesian languages, spoken in islands spread across Southeast Asia and the Pacific Ocean.

For each of these languages, the researchers combined measures of evolutionary distinctiveness (ED) and global endangerment (GE) to produce an “EDGE” score. The language with the highest score, which means it is extremely distinct yet nearly dying out, was Kavalan, a language native to Tai Wan. The next-highest scores went to Tanibili, an endangered language in the Solomon Islands.

By building trees for other language groups, language specialists could target preservation efforts and help reduce the loss of language diversity in the future, the researchers say.

32. What can an evolutionary tree show in biology? A. The relation among species. B. The concept of each species.

C. The conservation measures of each species.
