Too much expenditure on fashion
Recently, an increasing number of students are pursuing fashion in our class.
_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________The problem of robocalls has become so bad that we refuse to pick up calls from numbers we don’t know. Nearly half of the calls we receive are scams (欺诈). We’ve realized the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it’s too little. By the time these “solutions” become widely available, scammers will have moved onto cleverer means. In the near future, it’s not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you’re hearing is actually real.
That’s because there are many powerful voice manipulation (处理) technologies to be available. A company showed a new voice technology able to produce a convincing human-sounding voice able to speak to a receptionist and book a reservation without detection.
These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data disclosure of personal information has led to a situation where scammers can easily learn your mother’s name, and far more. Armed with this knowledge, they’re able to cheat the targeted people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you with a voice sounding exactly like your bank teller’s, misleading you to “confirm” your address and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.
We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by or abandoning phone calls altogether and moving towards data-based communications — using apps like WeChat and Alipay, which can be tied to your identity.

8 . Why isn’t science better? Look at career incentives.
There are often substantial gaps between the idealized and actual versions of those people whose work involves providing a social good. Government officials are supposed to work for their constituents. Journalists are supposed to provide unbiased reporting and penetrating analysis. And scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.
All too often, however, what should be just isn’t so. In a number of scientific fields, published findings turn out not to replicate (复制), or to have smaller effects than, what was initially claimed. Plenty of science does replicate — meaning the experiments turn out the same way when you repeat them — but the amount that doesn’t is too much for comfort.
But there are also ways in which scientists increase their chances of getting it wrong. Running studies with small samples, mining data for correlations and forming hypotheses to fit an experiment’s results after the fact are just some of the ways to increase the number of false discoveries.
It’s not like we don’t know how to do better. Scientists who study scientific methods have known about feasible remedies for decades. Unfortunately, their advice often falls on deaf ears. Why? Why aren’t scientific methods better than they are? In a word: incentives. But perhaps not in the way you think.
In the 1970s, psychologists and economists began to point out the danger in relying on quantitative measures for social decision-making. For example, when public schools are evaluated by students’ performance on standardized tests, teachers respond by teaching “to the test”. In turn, the test serves largely as of how well the school can prepare students for the test.
We can see this principle—often summarized as “when a measure becomes a target, it ceases to be a good measure”—playing out in the realm of research. Science is a competitive enterprise. There are far more credentialed (授以证书的) scholars and researchers than there are university professorships or comparably prestigious research positions. Once someone acquires a research position, there is additional competition for tenure (终身教授) grant funding, and support and placement for graduate students. Due to this competition for resources, scientists must be evaluated and compared. How do you tell if someone is a good scientist?
An oft-used metric (标准,度量) is the number of publications one has in peer-reviewed journals, as well as the status of those journals. Metrics like these make it straightforward to compare researchers whose work may otherwise be quite different. Unfortunately, this also makes these numbers susceptible to exploitation.
If scientists are motivated to publish often and in high-impact journals, we might expect them to actively try to game the system (钻空子). And certainly, some do—as seen in recent high-profile cases of scientific fraud (欺诈). If malicious (恶意的) fraud is the prime concern, then perhaps the solution is simply heightened alertness.
However, most scientists are, I believe, genuinely interested in learning about the world, and honest. The problem with incentives is that they can shape cultural norms without any intention on the part of individuals.

10 . In the fog of uncertainty about how new technology will change the way we work, policymakers around the world have flocked to the same idea. No matter what the future brings, they say confidently, we will need to upskill the workforce in order to cope.
The view sounds reassuringly sensible. If computers are growing smarter, humans will need to learn to use them to humans’ advantage. Otherwise, they may run the risk of being replaced by computers.
Research published by the Social Mobility Commission shows that workers with degrees are over three times more likely to participate in training as adults than workers with no qualifications. That creates a virtuous circle for those who did well at school, and vicious circle for those who did not. If the robots are coming for both the accountants and the taxi drivers, you can bet the bean counters will be more able to retrain themselves out of danger.
It is no good criticizing employers for directing investments at their highly skilled workers. They are simply aiming for the highest return they can get. And, for some types of lower-paid work, it is not always true that technological progress requires more skills. The UK’s latest Employment and Skills Survey, which is performed every five years, suggests the use of literacy and numeracy skills at work has fallen since 2012, even as the use of computers has increased. The trouble is, when the computer makes your job easier one day, it might make it unnecessary the next. Many of those affected by automation will need to switch occupations, or even industries.
It is time to revisit older ideas. The UK once had an energetic culture of night schools, for adults to attend after their day jobs. These institutions have been disappearing due to funding cuts. But a revival of night schools could be exactly what the 21st century needs.
It is still not clear whether the impact of new technology on the labour market will come in a trickle or aflood. But in an already unequal world, continuing to reserve all the lifeboats for the better-off would be a dangerous mistake.
A.Employers also invest more in better educated workers by launching employer-sponsored cmployee education programs. |
B.According to an Oxford University study, nowadays employers are more likely to hire the first-year apprentices. |
C.Rather than just “upskilling” in a narrow way, people could choose to learn an entirely new skill or trade. |
D.But the truth is, the people who are being “upskilled” in today’s economy are the ones who need it the least. |
E.People can effectively train or upskill themselves to meet their specific professional needs. |
F.But a retailer or warehouse company is not going to retrain its staff to help them move to a different sector. |
