PCs are no longer the only things that can be hacked(非法侵入). Anything with an electronic pulse, including cars, TVs and refrigerators, is now a target for hackers. Here are several strangest hacks that show where the future is headed:
Remote-controlling a car – Well-known security researcher Charlie Miller is able to control a car by accessing the automotive computer. In 2011, a security company figured out how to unlock a car and start it just by texting and back in 2010, someone hacked into100 cars in Texas, causing them to honk(鸣响)uncontrollably before he remotely disabled them.
Cyber Murder – In Season 2 of Show Time’s homeland series, hackers kill the US Vice President by hacking his pacemaker(心脏起搏器). Typical Hollywood B. S., right? No. It could actually happen. Well-known security researcher Barnaby Jack, who sadly passed away in July at the age of 35, had been prepared to demonstrate at Back Hat how to hack a pacemaker over Wi-Fi. The attack could kill a person by giving the pacemaker a high-voltage shock.
Spy Phone – By now, more people are becoming aware of the potential for a phone to be hacked. But what many fail to realize is the awesome potential of a smart phone to affect you, it has been hacked.
When Your TV Watches You – This type of hack makes it possible to monitor people in their homes via the internet. Smart TVs aren’t that common yet, but in the next few years they could become an important part of the living room, so watch out.
According to Cyber Murder, we know that Barnaby Jack ________.A.was killed by the attack over Wi-Fi |
B.was a well-known actor and researcher |
C.researched how to hack a pacemaker over Wi-Fi |
D.died at Black Hat when hacking a pacemaker |

【推荐3】Humans evolved (进化) from apes. This is what we learned in biology class. But what came before apes? Chinese scientists have discovered fossils that could enrich the evolutionary story of how humans evolved from fish.
According to four articles published in the journal Nature in late September, Chinese researchers found fish fossils that provide the “missing link” about the origin of the jaw (下颌),a key trait (特征) that 99.8 percent of vertebrate species (脊椎动物) have.
Zhu Min, a lead researcher of the studies from the Chinese Academy of Sciences, told China Daily that the findings drew a large amount of interest in the science world due to the importance of jaws in animal evolution. However, the rise of the jaw had been a mystery due to a lack of sufficient fossil evidence to support that jawed vertebrates lived 450 million years ago.
The latest findings made by Zhu’s team presented a set of five surprisingly well-preserved fish fossils that included three whole-bodied fish, helping scientists paint a more accurate evolutionary picture of the origin of the jaw. The fish fossils were discovered at two sites in Chongqing and Guizhou, whose strata (地层) date back to the Silurian Period (志留纪) that began around 440 million years ago.
These fossils show that jawed fish were already thriving in the world’s ancient oceans at that time. Later on, more diverse and larger jawed fish evolved and began to spread around the world, paving the way for some fish to eventually go on land and evolve into other animals — including humans.
“These fossils provide an opportunity to peek into the ‘dawn of fish’ and help scientists track many human body structures back to these ancient fish, thus filling some key gaps in the evolutionary history of how fish evolved into humans.” Zhu said.
The underlined word “thriving” in paragraph 5 probably means________.
A.growing well | B.decreasing slowly |
C.disappearing suddenly | D.changing quickly |
【推荐1】Alice Moore is a teenager entrepreneur (创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids’ teeth, instead of destroying them.
![](https://img.xkw.com/dksih/QBM/2024/3/8/3449110135767040/3455079212269568/STEM/1f5ec59bb978496ea2794e2f2be879bd.png?resizew=103)
It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, “Why can’t I make a healthy candy that’s good for my teeth so that my parents can’t say no to it?” With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.
With her dad’s permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.
Moore then used her savings to get her business off the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore’s product—CanCandy.
As CanCandy’s success grows, so does Moore’s credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she’s also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.
Meanwhile, with her parents’ help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn’t driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilicCandy’s profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.
What does Moore expect from her business?
A.To earn more money. |
B.To help others find smiles. |
C.To make herself stand out. |
D.To beat other candy companies. |
【推荐2】Examining the classroom practices of National Teacher of the Year winners and finalists, the study, by Michigan State University scholars, suggests successful educators aren’t afraid to push the boundaries by adding real world, cross-disciplinary(跨学科的)themes into their lessons.
The study, published online in the journal Teachers College Record, is one of the first in depth investigations of how teachers use creativity in the classroom.
“The best teachers are taking their own creative interests – from rap music to cooking to kickboxing – and are finding ways to include these into the curriculum,” said Danah Henriksen, lead author of the study. “They’re bringing together different subject matters and finding areas of connections so students can learn both in interesting ways.”
America’s test-driven educational policy, Henriksen argues, has impeded creativity in teaching and learning. Many teachers today struggle to balance high-stakes(高风险)testing and responsibility to act flexibly and independently in their classrooms.
“I think that there’s a lot of fear.” one of the award-winning teachers says in the study, “And when teachers are teaching in fear, they take few risks, for they have to consider exams and academic performance.”
The findings have major implications(含意)for teaching and learning. Teachers’ unique creative interests should be brought into classroom lessons, along with arts and music across varied academic content. Teacher education programs and professiona1 development courses should include a focus on real world. Administrators and policymakers should support opportunities for teachers to take creative and intellectua1 risks in their work.
“If we want teachers to be creative, we need to provide them with opportunities to bring those outside interests into their professional life,” said Mishra, study co-author and MSU professor of educational psychology and educational technology. “The point is to find what works for you, what is your passion and interest and how can you put that into what your students are learning. Finally, we teach who we are. That’s the most powerful finding.”
Many teachers are teaching in fear because ________.A.they don’t want to take risks in classroom |
B.the students are always troublesome |
C.administrators and policymakers don’t support them |
D.they’re worried about students’ academic records |
【推荐3】Monkeys seem to have a way with numbers.
A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward. The researchers then tested how the monkeys combined—or added—the symbols to get the reward.
Here’s how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.
After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.
When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate (低估) a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction (小部分) of the smaller number to it.
“This indicates that there is a certain way quantity is represented in their brains, ”Dr. Livingstone says. “But in this experiment what they’re doing is paying more attention to the big number than the little one.”
