d a way to grind the corn into flour, but the rocks on the island were not hard enough. I finally discovered that a very hard piece of wood would do. I used some cloth to separate the meal from the husks. Not having anoven, I made some square pots with lids and covered them with hot ashes. This baked the dough, and I had bread! I made my cave bigger again to hold the corn and flour so that I could make bread whenever I needed to.
I sometimes wondered how I could get to the land which was visible from the other side of the island. I went to the ship’s boat that was blown onto the beach in the shipwreck. However, I could not get it to the water. It was too heavy. I tried many different ways of doing it, but none of them were successful.

Fresh off his MasterChef Junior run, Evan Robinson, who is only 12 years old, is using his kitchen skills to raise money for Puerto Rico. The TV show contestant wanted to offer help after hurricanes(飓风) hit the country last September.
“I’ve been seeing, all over the news, people struggling,” Evan said. “They can’t get fresh water, electricity; they can’t get really anything. I know I’m just a kid, but I think if a lot of people do something, a lot of things will get better.”
He raises money by baking and taking online orders for homemade empanadas(馅 饼). He started cooking on a recent Friday night. By the next Sunday evening, he had filled orders for 420 empanadas — — roasted chicken, cheeseburger and vegetarian — — getting $18 for six empanadas and $30 for a dozen.
His mom, Veronica Robinson, helped him send the empanadas around the city.
“We’ve never done anything like this before,” she said. “But it’s a great idea, so I want to help him make it work.”
For Evan’s out-of-town friends and supporters, he has set up a crowdfunding(众筹) page. Through it, he’s hoping to raise $1, 500 in “virtual (虚 拟 的) empanadas”. This is because he heard on the news that it could take Puerto Rico years, maybe even 10 years, to recover(复 原) from the hurricanes. And he said, “Fruit pies are up next. And my baking will continue as well.”
It’s a difficult job, especially for a kid with homework and Boy Scouts and friendships to tend to. But he doesn’t seem worried.
“It’s what we’re supposed to do.” he said. “I’m a human. They’re humans. Why shouldn’t I help them?”
Indeed.

Bats are the only mammals that can fly a great distance, but they have another ability. Many bats live a very long time for an animal their size.
European researchers are studying bats to understand why they live so long. They hope to make discoveries to fight the aging process (过程) in human beings.
Last week, the group of scientists said they had found important biological qualities in some bat species. The group studied bat chromosomes (染 色 体), a line of genes found in the nucleus(核) ofcells. The scientists were most interested in parts connected to the ends of the chromosomes. They are called telomeres(端 粒). Telomeres protect the ends of chromosomes, which shorten each time a cell divides. Scientists believe this shortening process causes cells to break down. . A report on bats was published this month in the journal Science Advances.
Among the leaders of the study was Emma Teeling, a biologist with University College Dublin in Ireland. Teeling said studying long-living mammals that have developed ways to fight aging “is another way to prove the molecular(分 子) basis of extended ‘health length.’” She added that studying bats made scientists able to learn more about the processes “that drive healthy aging.”
The European researchers studied 493 bats from four bat species. The group used information that had been gathered over more than 60 years. Of these animals, the greater mouse-eared bat generally lived the longest, an average of 37 years.
C．We should help those who’re in need.
The scientists said this and a related species, which are grouped together under the name Myotis, had telomeres that did not shorten with age. Another Myotis bat holds the record for oldest age, reaching 41 years.
The scientists’ findings suggest that these bats’ cells have the ability to keep and repair their telomeres. This, they said, helps guard against the aging process. Based on its body size, a bat like the greater mouse-eared bat would be expected to live four years. But, these mammals have been found to live nearly 10 times longer than that. The scientists found that Eighteen of these are bats. The only exception is an unusual African rodent, the naked mole rat.
42．Which sentence can be put at the end of Paragraph 3?
A．This makes scientists able to study bats. B．That’s why bats can fly a great distance. C．They say this is what causes aging.
D．They discover the cells connected to humans. 43．Why do some species of bats live a very long time?
A．Because they have a line of long-living genes out of the cells. B．Because their cells have the ability to keep and repair their telomeres. C．Because they have another ability to live longer without any food or water. D．Because telomeres protect the ends of chromosomes to stop cells dividing. 44．The underlined word “that” refers to .
A．four years
B．body size
C．the aging process D．the ability to repair
