When Jeff Sparkman draws his cartoon superheroes, he often has to ask other people to tell him what color his characters turned out to be because he's color-blind. Now, a new smart phone application can help him figure out what colors he's using and how the picture looks to others.
The DanKam app, available for iPhone and Android for $2.99, is an application that makes the vague colors that one percent of the population with color-blindness sees more like the "true" colors as everyone else sees them. In America, around 32 million color-blind Americans---95% are males---can soon have their life improved.
"DanKam takes the stream of data coming in through the phone's camera and changes the colors slightly so they fall within the range that people who are color-blind see," developer Dan Kaminsky told CNET. He came up with the idea after watching the film Star Trek with a color-blind friend.
It was then that he got to know more about colorblindness like its varying types and degrees. A vast majority, for instance, have trouble seeing red or green due to a genetic defect(缺陷). Blue-yellow colorblindness, however, is rarer and develops later in life because of aging, illness or head injuries, etc.
What the DanKam app attempts to do is to clean up the color space of the image signal so that colors can be seen to those suffering from viewing problems. “You can customize the app to fit your needs. There is a range and not everyone who is color-blind sees things the same.” Says Kaminsky.
Sparkman, a copy editor at CNET, tried out the app and was pleased with the results. "It would be useful for dressing for a job interview," he said. But using it for his art is “the most practical application." It worked well on LED and other lights on electronic devices, which means Sparkman can now identify the power light on his computer display as green.

Vegetable gardens may not be as visually pleasing as the variety of flowers, but Floridians looking to save some green by growing their own salad fixings can soon do so without fear. Gov. Ron DeSantis this week signed a law that bans local governments from carrying orders against homeowners from raising veggies in their yards.
The law, which takes effect July 1, puts an end to that particular power of towns and cities across the state to prohibit vegetable gardens for “aesthetic（审美的）purposes”.
The issue became a cause after a couple living in Miami Shores Village opposed the decision of a $ 50 a day fine for growing vegetables in their front yard, as they’d done for years.
Hermine Ricketts and her husband Tom Carroll fought City Hall in a case that wound its way up the state’s court system, with judges consistently ruling against their money-saving and health-conscious project.
After the Florida Supreme Court ruled in favor of Miami Shores’ right to control design and landscaping standards, the couple replaced their vegetables with pink flamingos (红鹳花) .
Their cause was not lost, however. State lawmakers proposed and passed a law that effectively voids the court rulings, with Rob Bradley, who sponsored the bill, reportedly calling the village’s action a “vast overreach”.
The lawmaker noted the difficulty that many families experience getting fresh and affordable food, calling bans against vegetable and fruit gardens ridiculous.
About a third of all households in the U. S. grow some of their own food, according to the National Gardening Association. The group says a 600-square-foot garden that costs around $ 70 a year to keep can grow 300 pounds of fresh produce worth about $ 600 annually.
1.Why will some Floridians plant salad fixings?
A.To protect the environment. B.To beautify their home.
C.To build their own gardens. D.To cut daily expenses.
2.What can be known about the couple from the passage?
A.They started a public health-conscious campaign.
B.They never gave in to the Miami Shores’ demand .
C.They were fined $50 a day by Miami Shores Village.
D.They were not backed by the Florida Supreme Court.
3.What does the underlined word “voids” in paragraph 6 mean?
A.Hides. B.Cancels.
C.Prevents. D.Values.
4.What does Rob Bradley think of the couple’s action probably?
A.It’s sensible. B.It’s ridiculous.
C.It’s ambitious. D.It’s costly.

阅读下面短文，根据其内容写一篇 60 词左右的内容概要。
Perhaps you’ve heard the old saying “curiosity killed the cat.” It’s a phrase that's often used to warn people - especially children - not to ask too many questions. Yet it’s widely agreed that curiosity actually makes learning more effective. In fact, research has shown that curiosity is just as important as intelligence in determining how well students do in school.
Curiosity can also lead us to make unexpected discoveries, bring excitement into our lives, and open up new possibilities. In science, basic curiosity-driven research can have unexpected important benefits. For example,one day in 1831, Michael Faraday was playing around with a coil and a magnet when he suddenly saw how he could produce an electrical current. At first, it wasn't clear what use this would have, but it actually made electricity available for use in technology, and so changed the world.
However, curiosity is currently under the biggest threat, coming from technology. On one level, this is because technology has become so advanced that many of us are unable to think too deeply about how exactly things work any more. While it may be possible for a curious teenager to take a toaster apart and get some sense of how it works, how much do you understand about what happens when you type a website address into a browser? Where does your grasp of technology end and the magic begin for you?
In addition to this, there’s the fact that we all now connect so deeply with technology, particularly with our phones. The more we stare at our screens, the less we talk to other people directly. All too often we accept the images of people that social media provides us with. Then we feel we know enough about a person not to need to engage further with them.
That means we end up inside our own little bubbles, no longer coming across new ideas. Perhaps the real key to developing curiosity in the 21st century, then, is to rely less on the tech tools of our age.

Lewina Lee, lead author of the study, said, “A lot of evidence4.(suggest) that exceptional longevity( 长 寿 ) is widely accompanied by a longer span of good health and living5. disability. Therefore our findings raise an exciting possibility6. we may be able to promote health and happiness by7.(develop) positive attitudes such as optimism.”
However, the study doesn’t suggest that we should aim for great pleasure. Sadness is8. important part of the human condition. Any normal person sometimes experience disappointment, ambitions and the9.(lose) of loved ones. But for many people, these matters of human existence 10.
