Depending on which late-model vehicle you own, your car might be watching you — literally and figuratively — as you drive down the road. It’s watching you with cameras that monitor the cabin and track where you’re looking, and with sensors that track your speed, lane positions and rates of acceleration.
In addition to providing these functions, this data collection is a potential privacy nightmare. The information can reveal your identity, your habits when you’re in your car, how safely you drive, where you’ve been and where you regularly go.
There is a trade-off (权衡) between the quality of the driving experience and the privacy of drivers, depending on the level of services and features. Some drivers may prefer to share their biometric data to facilitate accessing a car’s functions and automating a major part of their driving experience. Others may prefer to manually control the car’s systems, sharing less personally identifiable information or none at all.
At first glance, it seems the trade-off between privacy and driver comfort cannot be avoided. Car manufacturers tend to take measures to protect drivers’ data against data thieves, but they collect a lot of data themselves. And as the Mozill a Foundation report showed, most car companies reserve the right to sell your data.
Researchers are now working on developing data analytics tools that better protect privacy and make progress on eliminating the trade-off. For instance, over the past seven years, the concept of federated machine learning has attracted attention because it allows algorithms (算法) to learn from the data on your local device without copying the data to a central server. Google’s Gboard keyboard benefits from federated learning to better guess the next word you are likely to type without sharing your private data with a server. There are other techniques to preserve privacy as well, such as location obfuscation, which alters the user’s location data to prevent the location from being revealed.
While there is still a trade-off between user privacy and quality of service, privacy-preserving data analytics techniques could pave the way for using data without leaking drivers’ and passengers’ personally identifiable information. This way, drivers could benefit from a wide range of modern cars’ services and features without paying the high cost of losing privacy.

【推荐1】Japans biggest airline is betting that the future of travel isn't traveling at all. For the last month, a married couple has been interacting with a robot -called an Avatar -that's controlled by their daughter hundreds of miles away. Made by ANA Holdings Inc. it looks like a cleaner with an iPad attached But the screen displays the daughter's face as they chat, and its wheels let her move slowly about the house as though she's really there.
"Virtual travel"is nothing new, of course. Storytellers, travel writers and artists have stimulating(刺激)the sense of armchair tourists for centuries. It's only in recent decades that frequent, safe travel has become available to the non-wealthy.
Yet even as the world's middle classes climb out of the armchair and into economy-class seats, there are signs of a post-travel society coming into being. Concerns about sustainability(可持续发展)are having an negative influence on carbon-intensive airlines. And the aging of wealthy societies is both slowing down physical travel and creating demand for various ways to experience the world. For the travel industry, virtual (虚拟的)reality offers an attractive response to these trend.
Of course, far- out technologies encourage far-out claims. ANA doesn't plan to start selling Avatars until next year. Profits, too, will probably be difficult to achieve: according to one investigation, the global market for this kind of technology will be worth only about $300 million by 2023. By contrast, ANA's traditional travel business brought in more than $19 billion last year .
But if the business case for virtual vacations is still weak, the market for technologies that bridge physical distances between families and coworkers seems likely to soy expand.ANA's robots may not replace its airplanes any time soon, but they ' ll almost certainly be a part of travel’s high-tech future.

【推荐2】Bangladesh has a large population. The nation depends on rice as its main food. Growing rice requires a lot of water and energy, especially during the dry season from January to June when farmers mostly rely on groundwater. This results in serious reduction of groundwater as well as greenhouse gas emissions(排放).
Researchers from the University of Washington and Bangladesh’s Ministry of Agriculture have developed a system called Integrated Rice Advisory System (IRAS), which uses satellite data from NASA and its partners to give farmers important information.
IRAS works by combining satellite data on water use, rainfall, and weather forecasts with crop water demand(需求)characteristics to produce location-specific suggestions for farmers. The suggestions tell farmers how much water they have, how much they are using, and how much they need for their crops. They also warn farmers if they have over-or under-watered their fields.
The IRAS team states that the system will help reduce agricultural water waste by about 30 percent, cut fuel use by 45 percent, save S115 million yearly, and lower carbon emissions by 300,000 tons per year.
IRAS is an example of how global cooperation and the sharing of important data among nations can help improve food security, water management, and environmental protection around the world. “In addition to being affordable and convenient for farmers, the method can help the world become more water-efficient and energy-efficient in growing food,” said Faisal Hossain, leader of IRAS.
The IRAS team completed its first nationwide effort in June 2023, after working with staff from Bangladesh’s Department of Agricultural Extension and Agro-Meteorological Information Service to set up the system. Faisal Hossain and his colleagues hope to broaden the reach of IRAS in the future, and apply it to other crops that demand large amounts of water, like sugar cane. “We believe that this affordable tool will be applied to any area where we know what crop is being grown and what their crop water demand characteristics are,” he said.

【推荐3】Personalized medicine changes conventional medicine which typically offers blanket recommendations and offers treatments designed to help more people than they bam but that might not work for you. The approach recognizes that we each possess unique characteristics, and they have an out size impact on our health.
Around the world, researchers are creating precision tools unimaginable just a decade ago: superfast DNA sequencing(排序); tissue engineering, cell reprogramming, gene editing, and more. The science and technology soon will make it possible to predict your risk of cancer, heart disease, and countless other illnesses years before you get sick. The work also offers prospects for changing genes in removing some diseases.
Last spring, researchers at the National Cancer Institute reported the dramatic recovery of a woman with breast cancer, Judy Perkins. The team, led by Steven Rosenberg, an immune(免疫的) treatment pioneer, had sequenced her cancer cells’ DNA to analyze the sudden change. The team also removed a sampling of immune cells and tested them to see which ones recognized her cancer cells' genetic faults. The scientists reproduced the winning immune cells by the billions and put them into Perkins to attack her cancer cells. More than two y cars later. Perkins, a retired engineer from Florida, shows no signs of cancer.
Thirty years ago, scientists thought that it would be impossible to understand our genetic rules and sequence the 3.2 billion pairs of different elements in our DNA. “It was like you were talking fairytales,” Kurzrock said. “The conventional wisdom was that it would never happen. Never And then in 2003, never was over.”
It took the Human Gene Project 13 years, roughly one billion dollars, and scientists from six countries to sequence one gene complex. Today sequencing costs about a thousand dollars. The latest machines can produce the results in a day. The technology, combined with advanced cell analysis, clarifies the astonishing biochemical variations that make every human body unique.

【推荐1】Imagine ordering something online. Then, imagine that item being delivered in just a few minutes by a drone. Believe it or not, this may be probable in the near future. Drones have been used by militaries since the 1970s. They refer to them as unmanned aerial vehicles, or UAVs. However, over the last two decades, drone technology has advanced rapidly and is increasingly available to the public. In fact, drones have already started doing work in many different industries. But is this going to be a good thing or a bad thing?
On the plus side, drones can do many things faster and more efficiently than people. For example, during an emergency, drones can quickly locate injured people by using special cameras. They can also distribute food, water, and medical supplies to people in hard-to-reach or dangerous places.
Drones are not just flying vehicles. Some travel on land and sea, and some even work on farms! Selfdriving tractors are being developed to help out farmers, and flying drones may soon be used to spread seeds. As for the sea, an autonomous sailboat was recently launched to collect data about the ocean and atmosphere.
Drones can truly help people in many ways. They are starting to be used in a wide variety of applications, from healthcare to mining. Even though drones can be very useful, some people believe drones also have some major problems that should be taken into consideration.
One of the biggest concerns about drones is privacy. What if a drone enters your house and takes a look around? Depending on local regulations, there may not be laws preventing drones from doing this. Drone technology is changing so quickly that it’s hard for governments to keep up!
Drones are often used to fly around and collect data. This data is then uploaded to the cloud. Unfortunately, hackers are sometimes able to steal the data when it is being uploaded. Flying drones can also pose a danger to aircraft. Many airports have reported close calls with drones.
Drones are not perfect. In the wrong hands, they can be used for criminal purposes, and even as weapons! However, most people think the positives of drone technology outweigh the negatives. Thus, it is likely that you will be seeing more and more drones in the near future. What is your opinion on drones? Do you think they are worth having around?
1. According to the passage, drones can be applied in many areas EXCEPT that______.A.drones can quickly deliver the items you order online to your home. |

【推荐2】Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not bring so much material home in the first place.
The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
1. What does the underlined word “over-consumption” refer to?A.Using too much packaging. |

【推荐3】Nearly half of us make New Year’s resolutions, but less than ten percent of us actually keep them. This can be due to lack of motivation or loss of interest, but it’s time for us to figure out ways to finish what we’ve started.
Lack of honesty
Are you truly devoted to running a marathon, losing weight, or whatever else you are promising to do? Be honest with yourself. We often find ourselves committing to things because we think we should.
While you may have the best intentions with your resolution, you could be putting unnecessary pressure on yourself. Rather than associating the New Year with resolutions or changes you need to make, consider it a time for reflection on things you wish to work on throughout the year.
If your goal was to send out ten resumes (简历) for a new job and you only sent out five, don’t beat yourself up for it. Rather, congratulate and reward yourself for making the effort toward your goal. That will give you the energy to continue working towards your initial (最初的) goal.
Giving up too easily
Whether you get discouraged or simply lose interest, giving up too easily is a big resolution breaker. Many people make their resolutions believing they can accomplish them.
A.Wrong perspective (视角) |
B.Narrow your resolution |
C.Don’t waste your time on that. |
D.But the excitement wears off and other priorities appear. |
E.They thought they could stick to it because it’s what they want. |
F.Here are reasons people don’t stick to their New Year’s resolutions. |
G.Stop thinking about what you have not accomplished and focus on what you will accomplish instead. |
【推荐1】What do Harry Potter, Katniss Everdeen, and Frodo all have in common with the heroes of ancient myths (神话)?Joseph Campbell studied myths from all over the world and published a book called “The Hero with a Thousand Faces”, retelling dozens of stories and explaining how each represents the mono-myth, or Hero’s Journey. So, what is the “Hero’s Journey”?
He thinks of it as a cycle in his book. The journey begins with the hero receiving a mysterious message, an invitation, or a challenge. After crossing the threshold from his safe home to adventure, with some help probably from someone older, wiser, our hero solves a riddle, slays a monster, escapes from a trap. The hero’s darkest hour then comes, when he faces death and possibly even dies, only to be reborn. As a result, the hero claims some treasure, special recognition, or power, which can vary between stories. After all that adventure, the hero returns to his ordinary world, but upgrades to a new level. Nothing is quite the same once you are a hero.
The Hero’s Journey myth exists in all human cultures and keeps getting updated, because we humans reflect on our world through symbolic stories of our own lives. You leave your comfort zone, have an experience that transforms you and then you recover and do it again. You don’t literally slay dragons or fight Voldemort, but you face problems just as scary. Joseph Campbell said, “In the cave you fear to enter lies the treasure you seek.”
What is the symbolic cave then you fear to enter? Auditions (试镜) for the school play? Baseball tryouts? Love?
Watch for this formula (公式) in books, movies, and TV shows you come across. You will certainly see it again. Also be sensitive to it in your own life. Listen for your call to adventure. Accept the challenge. Conquer your fear and claim the treasure you seek. And then, do it all over again.
1. What is the correct order of the “Hero’s Journey”?①Return to the ordinary world but upgrade to a new level.
②Receive a call to adventure and assistance from a wiser man.
③Set out on the adventure and go through a series of tough trials.
④Face a life-or-death crisis and be reborn with some special power.

【推荐2】Earlier this month, British supermarket chain Morrisons announced that it would be removing “use by” dates on most of its milk. The idea behind this is to discourage people from throwing milk away based on a date, rather than sniffing (闻) and looking at it to determine whether it’s still safe for consumption.
The fact is that significant amounts of food get wasted every year by people blindly following expiration dates, rather than their senses. What makes matters worse is that most dates don’t mean much, anyway. They’re assigned somewhat randomly by food manufacturers that are not held to any regulatory standards for what determines a safe date nor what expertise (专门知识) is required to make such a judgment call—so it makes sense that they’d be too cautious.
What I find amusing, however, is that many people seem to be horrified by this approaching absence of “use by” dates.
In fact, I never look at expiration dates when I shop. To me, it’s as if they don’t exist. To be clear, I am not an absent-minded shopper. I pay close attention to both packaging and price. Despite having a full cart at checkout, I could tell you the exact price of every item in it. Any time I see a clearance rack (清仓货架) at the store, that’s usually where I go first because it’s exactly the stuff I want to buy—the cheaper, the better! If there’s any heavily discounted product that I’d normally use, I will certainly take it. Often, I’ll mentally adjust my weekly menu plan on the spot, based on what I find.
The handful of times I have looked at expiration dates have been for short-lived items like prepackaged salad greens. What I’ve found, however, is that the dates mean little. Even a package that claims to be fresh can still have rotten yellow leaves at the bottom, which turns me off. Therefore, the expiration date means next to nothing, but my visual assessment, combined with my intention for when I plan to eat it, is far more useful.
Food is your friend. Food is not out to kill you!
1. Why will Morrisons remove “use by” dates on most of its milk?A.To reduce food waste. | B.To improve customers’ senses. |

【推荐3】We can probably all agree that it is good to be kind, moral (道德的) to be kind, nice to be kind, but does it lead to success in life? After all, isn’t kindness about putting other people’s interests first? Doesn’t it require self-sacrifice?
Yet consider these well-known people: James Timpson, boss of the Timpson chain of shoe repairers; Jacinda Ardern, the prime minister of New Zealand. These two are clearly “winners” in their fields, and yet both put kindness at the heart of their strategies for success. What they have found is that taking a more compassionate (同情心) and apparently “softer” approach to business, politics and sports management brings positive results, not just for the benefit of people who work for them, but for their own benefit. The traditional idea that you have to be cruel, driven and focused on number one if you want to achieve success is being discredited (不足为信的).
It’s notable (值得注意的)that in the field of business research, kind leadership is more often referred to as “ethical” (有道德的) leadership, maybe because it sounds less soft. But whatever you decided to call it, studies have shown that it can result in a more positive atmosphere at work and that employees perform better too. There’s evidence that even small acts of kindness and cooperation by anyone can make a difference in a workplace. An example might be getting the printer mended, rather than leaving it broken for the next person to find, or watering the plants in the office. These actions aren’t required as part of the job, but if we carry them out, the working environment is a little better for everyone.
Of course, there are still plenty of examples of people who do well in life, but they are self-centered and unkind to others. But the point is that despite what we might see, you don’t have to be hard-nosed (不讲情面的) to get on in business or other highly competitive walks of life. You can’t be a winner simply through being kind of course — you need motivation, dedication and skills too — but there’s more and more evidence that showing some kindness as you pursue your goal is no barrier (障碍) to success.
