    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough a novel model system for scientists studying human biology and disease.

(1)、What do we know about the technology called SCNT?
A、It created the first two primates. B、It may contribute to editing the DNA C、It can divide an early-stage embryo into several cells. D、It produced two cloned monkeys with different genes.
(2)、What does the author mean by “pouring water on the idea” in paragraph 2?
A、Keeping a hot topic of it. B、Having a low opinion of it. C、Attaching no importance to it. D、Adding supportive evidence to it.
(3)、What is the scientists' purpose to clone these monkeys?
A、To help with the study of human diseases. B、To serve as a stepping stone to their reputation. C、To prepare for their research on human cloning. D、To raise money for holding an exhibition of novels.
(4)、What can we infer from the passage?
A、New techniques seem to be pointless. B、Cloning humans is already on its way. C、Society won't agree to clone another monkey. D、The success rate of cloning a monkey was not high.

    Aunt Karen always had a special place in my heart. When I was growing up, I knew I could count on her to have room for me on her lap and words of love and encouragement when I needed to hear them. When she died five years ago, I was devastated. The whole family was still in shock when her husband, Uncle Ronnie, died a week later. I longed to have a small item of Aunt Karen's to remember her by, but seeing her children and grandchildren overcome by the grief of this double loss made me shy away from asking.

    A few months after Aunt Karen's death, I was on my way to work when I saw Rescued Treasures, a local second-hand store. I only had a couple of dollars on me and didn't really intend to buy anything, but I stopped anyway just to look inside. I had been shopping around for a few minutes when a small, black handbag caught my eye. It wasn't fancy or special. I didn't really need a handbag and continued to look around the store, but something kept drawing me back to that handbag. Finally, I checked the price tag (标签). It was just one dollar.

    The handbag stayed in the back of my car for weeks until I came upon it during a car clean-up. I opened it up. I couldn't believe it. They hadn't even cleaned it out. It was still full of junk, old candy wrappers, old receipts (收据) and used paper. Usually the store emptied things inside, so there wouldn't be any surprises for a new owner.

    I threw away some wastes, and sorted through the receipts, when I found one item in the small inside pocket. It was an insurance card with the name “Karen Stair” written on it. I began to cry. My beloved Aunt Karen. This was her handbag.

    On Aug 29, 1988, the University of Wisconsin-Madison juniors Tim Keck and Christopher Johnson published the first-ever issue of The Onion. The two founders claimed it was the “finest news source” in the US. 25 years later, the news has become one of the most established media presences in the US. But don't expect accuracy and timeliness from it, because The Onion only publishes fake news or news satire (讽刺). Its aim is to make readers laugh and see things from a different angle.

    Will Tracy, The Onion's editor-in-chief, told the NPR in an interview. “The stories are presented in that sort of news voice which improves the news to a certain level of importance. The news isn't actually understandable but it has an ability to elegantly locate a problem with concise and plain words.” For example, when George W. Bush became the US president in 2001, The Onion published a satire piece predicting massive debt and a huge growth in military spending. The headline said it all—Bush: “Our long national nightmare of peace and prosperity is finally over”.

    Traditional media outlets are cautious when reporting sensitive topics such as religion and race. Tracy says/‘Nothing is off limits for The Onion, no matter how uncomfortable they may make some readers.” But editors at The Onion do stand a fine line, as Tracy explains: “What you have to be really careful about is what the target of the joke is. If the target of the joke is wrong, then it doesn't feel right and it also doesn't feel funny.” The Onion made the public outrageous when earlier this year, it tried to make fun of a 9-year-old Oscar-nominated (奥斯卡提名的) actress by using highly impolite language. It later apologized.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components," said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. "The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own," he said.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to," said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically, it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. "You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead," he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis."
