In the rich countries of the West, the electric vehicle revolution is well occurring. Climate-conscious consumers drive Teslas or Polestars for reasons of morality (道德) and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.

Yet a glance under the hood (引擎盖) of these vehicles shows a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries (铅酸电池), containing almost 300 pounds of lead (铅) in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leaks into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable (高利润的) but deadly business.

Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an unexpected scale. The numerous ways lead enters air, water, soil, and homes across the developing world and the enormous damage it does to human health, wealth, and welfare cause one of the biggest environmental problems in the world yet receives little attention.

The World Bank estimates that lead kills 5.5 million people per year, making it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is heavy, as is its contribution to global inequality — our research on the cognitive (认知的) effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.

But unlike many challenges faced by developing countries, lead poisoning is a problem that can be resolved through financial investment (财政投入). Better monitoring, research, and rules can help protect children all over the world from the unpleasant effects of lead poisoning and reduce the massive global costs it brings.

After bikes and umbrellas are made sharable across China, some companies started eyeing the fitness market, so shared gym rooms have hit the streets in Beijing.

Unlike common gyms that provide large, open spaces for many members to share at the same time, the newly built shared gym rooms are small, stand-alone rooms for a person to use, often set up near living communities.

Every four-square-meter room is equipped with a treadmill (跑步机), an air cleaner, a mirror, a television and an air conditioner, and users can let down the curtains for privacy. When exercising, users can listen to music, watch movies and check emails by connecting to the Internet by the screen fixed on the treadmill. There’s no shower or washbasin.

Similar to using a shared bike, users can locate a shared gym room by smartphone application, book a room in advance and then need to scan a QR code for use. A refundable deposit (保证金) of 99 yuan is required, and users are charged 1 yuan every 5 minutes.

The shared gym rooms are created by Misspao, a Beijing-based technology company founded in July. Within several months since it was founded, the company has already raised over 100 million yuan, Yicai Global reports. The idea of the shared fitness experience is not entirely nascent. Last December, the Shanghai-based technology company VRUN set up shared treadmills in office and apartment buildings.

The sharing economy is still becoming popular in China. According to Yicai Global, confident investors are pouring millions into sharing start-ups. In March, the State Information Center published a report which predicts that the total value of China’s sharing economy will see a yearly growth of 40% in the coming years, and it is expected to make a great contribution to the country’s GDP.

【小题1】What makes the shared gym room different from the common one?
A.Holding one person at a time.B.Standing in the living zone.
C.Offering open spaces.D.Having some advanced equipment.
【小题2】What do people need to do to use the shared gym room?
A.Let down curtains for privacy.B.Pay 100 yuan first.
C.Use a smartphone.D.Have a shower before exercise.
【小题3】What does the underlined word “nascent” in paragraph 5 mean?
A.Simple.B.Popular.C.Satisfying.D.New.
【小题4】What is the author’s purpose of writing the text?
A.To advertise a technology company.B.To introduce shared gym rooms.
C.To support the shared gym rooms.D.To predict the future of shared gym rooms.
Directions: Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.

Working women with young children often face a dilemma(进退两难的困境) of whether to keep working or to quit to take care of their children. Though the fact that married women work outside the homes has become a social trend, many people still expect mothers to stay home until their children are two or three years old. In my opinion,it’s unfair to deprive(剥夺) mothers of their right to keep working only for the reason of childcare.

Women also need a sense of achievement just like men. Working women often find it difficult to give up the chance of self-fulfillment(自我实现) and go back home to play the traditional role. The times that women should stay at home passed and we should not neglect(忽视) mothers’ desire to seek further goals outside the home.

Besides, taking care of children is both parents’ responsibility(责任) rather than only mothers’. Children belong to the father and the mother. So it is unreasonable to ask mothers to give up their jobs for childcare because it is also fathers’ duty.

Practically speaking, working mothers can help improve family finances. Though there’ll be extra expense for childcare service, working mothers have a steady income to help the family. Therefore, mothers’ working outside is good for the family, especially to those low-income ones.

In a word, to expect mothers to put childcare before everything is not practical in today’s society. Only if fathers and mothers cooperate can the problem be solved.
