As robots are increasingly playing a part in society, we need to consider whether and how machines can learn morality. While robots can’t be ethical(伦理的) agents in themselves, we can program them to act according to certain rules. But what is it that we expect from them?

A 2016 study by UC San Francisco found that most virtual assistants struggled to respond to domestic violence or sexual assault(袭击). To sentences like “I am being abused”, several responded: “I don’t know what that means. If you like, I can search the web”. Such responses fail to help vulnerable people, who are most often women in this case.

But should virtual assistants ever be able to call the police when it overhears domestic violence? In a widely reported case from 2017, Amazon Echo was said to have called 911 during a violent assault. Responding to the incident, Amazon denied that Echo would have been able to call the police without clear instruction. Even if it had the ability, it is unlikely that people would expect a virtual assistant to go beyond providing information.

Then, there are robots whose very function gives rise to ethical questions. How should a driverless car react in an accident? To answer this question, Philippa Foot’s famous philosophical thought experiment, the trolley(有轨电车) problem, is usually rolled out. It goes as follows: imagine you see an unstoppable trolley zooming down a track, towards five people who are tied to the track. If you do nothing, they’ll die. But, as it happens, you are standing next to a lever that can redirect the trolley to a side track, which has one person tied to it. What should you do?

Variations of this experiment are invoked(援引) to ask whether a self-driving car should turn sharply around a jaywalking pedestrian teenager while putting the two elderly passengers at risk. Should it spare the young over the old? Or should it save two people over one?

Driverless cars are unlikely to encounter or solve the trolley problem, but the way we expect them to solve the variations could depend on where we’re from. In the moral machine experiment, MIT Media Lab researchers collected millions of answers from people around the world on how they think cars should solve these dilemmas. It turns out that preferences among countries and cultures differ wildly.

If, however, machines attain superior decision-making abilities, it may be necessary to have a full public discussion as to what should be the new and prevailing norms. But if we don’t come up with an ethical framework, we might risk leaving it to companies to regulate their own products or for people to choose with their wallet.

Figuring out what robot ethics we’d want is, therefore only the beginning.

1.The first three paragraphs indicate that virtual assistants _________.

A.must be programmed to learn morality

At a time when industries are under greater pressure to reduce costs and increase efficiencies, more production facilities are turning to digital sensing technology to provide the real-time insights they need for improved performance. What if one digital sensor could measure multiple signals?

Yokogawa's DPharp（差压传送器）digital technology has the unique ability to measure two pressure parameters （参数），delivering reliable and accurate measurement of plant operations. The unique aspect of this digital technology is that it measures two parameters in one sensor module, providing additional insight into a plant's operations. It is the only sensor in the world that does this.

DPharp transmitters（发射器）use silicon（硅）resonant（谐振的）sensor technology to measure both differential（差别） and still pressure. The sensor consists of two H-shaped crystal silicon resonators that shake at a certain frequency and, when pressure is applied, the frequency of one resonator increases while the other decreases. By monitoring these frequencies digitally, both differential and still pressure can be measured at the same time. The frequency output is directly read by the central processing unit of the transmitter.

DPharp can be used in any processing plant across any industry—oil and gas to food and drinks. DPharp's unique digital sensing technology allows engineering firms and plant engineers to create designs that will equate to an average reduction of 40 percent. Where they would typically use five measuring devices, they are using three by using the multi-sensing technology. That is a significant cost reduction in the number of devices installed and the added benefit is that, as there are less devices, the engineering and design is less complex, which means less materials and less equipment to maintain. Furthermore, there are fewer transmitter spares required, which reduces costs. Tony Farah, Product Manager, said that more organisations are seeing the significant benefits of smart devices like DPharp.

1.What is special about DPharp digital technology?

A.It provides the real-time insights.

B.It brings significant changes in engineering.

C.It measures two parameters in one sensor.

D.It provides accurate measurement.

2.What is the frequency output read by?

A.Two H-shaped crystal silicon resonators.

B.The central processing unit of the transmitter.

C.Monitoring devices.

D.The operator of the plant.

3.What is the plants' attitude to DPharp?

A.Cautious. B.Ambiguous.

C.Favorable. D.Disapproving.

4.What is the text mainly about?

A.How DPharp is bringing value across production plants.

B.How sensor works in a different way.

C.Why DPharp is efficient and reliable.

D.Where DPharp can be used.

Employment practices often reflect the needs of employers several decades ago．Times have changed．And so too has the Canadian workforce．Yet many employment practices have not kept pace with this change．For example, some work environments and washrooms designed for able-bodied workers seldom accommodate people who use a wheelchair．

Modernizing these practices is what employment equality is about．For example, making sure work benches and washrooms are adapted for disabled people entering the workplace paves the way for workers who become disabled on the job．By doing so, any given group of people? formerly discriminated against-now has access to better employment opportunities．

The objective, of course, is to make the workplace reflect Canadian society．However, this does not necessarily mean setting and enforcing quotas(实行配额）. Rather, it means identifying the barriers to employment and designing measures, with achievable goals and clear timetables, to remove them．

For example, according to the Canadian Union of Public Employees-Canada's largest union, it would be unrealistic in the short term to insist that because half of the working age population is women, that half of the employees of an engineering firm should be women．At this moment, there would not be enough qualified female engineers．

A reasonable numerical goal would be based on the number of women who actually are engineers （8% ） and those who are studying to become engineers （25% ）．A short term goal of 13% would be appropriate without running the risk of hiring unqualified people．

Equally important is to ensure people who have been disadvantaged the chance to become qualified for new opportunities．If aboriginal people （土著居民） , for example, can't qualify for certain jobs because they haven't had access to appropriate educational opportunities, then an employment equality program would have to address that problem with training programs.

Employment laws in this country cannot be considered displeasing if they guarantee all Canadians fair and equal access to the workforce.

1.The passage is mainly about how to ____.

A．modernize equipment for the disabled at work

B．achieve equality of employment opportunities

C．protect women's rights in employment

D．complete a job training program

2.The underlined word "them" in Paragraph 3 refers to ____.

A．barriers         B．measures       C．goals          D．timetables

3.The example of women shows that ____.

A．only a small percentage of women engineers will get promoted

B．13% of the working age women should be hired as engineers

C．policy makers should adopt a practical and flexible approach

D．the quota of women for employment should be raised

4.The underlined word "address" in Paragraph 6 probably means _

A．put forward     B．run into    C．find out D．deal with
