1 . In the rich countries of the West, the electric vehicle revolution is well underway. Climate-conscious consumers drive Teslas or Polestars for reasons of morality 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 reveals a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries, containing almost 300 pounds of lead in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leak into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable 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 extraordinary 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 — causes one of the biggest environmental crises in the world yet receives little attention.

The World Bank estimates that lead kills 5. 5 million people per year, which would make 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 extraordinary, as is its contribution to global inequality — our research on the cognitive 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 is fixable with some attention and a relatively modest financial investment. Better monitoring, research, and rules can help protect children all over the world from the dreadful effects of lead poisoning and reduce the massive global costs it brings.

2 . There are hundreds of great national nature reserves in China. Now feast your eyes on the following amazing ones.

Qinghai Lake National Nature Reserve

Qinghai Lake, China’s largest saltwater lake in Qinghai Province, is a key body of water for lots of animals and birds. As an important stopover, migratory birds (候鸟) would rest in this area during their movement trip every year. The reserve became a national nature reserve in the year of 1997.

Bayanbulak National Nature Reserve

The only Bayanbulak Wetland, in Xinjiang Uygur Autonomous Region, is at the foot of Tianshan Mountains, which makes itself suitable for migratory birds. Bayanbulak means “rich spring water” in Mongolian, meaning that the area is rich in water. Every year, swans (天鹅) from different places fly here for nesting, which became a national swan reserve in 1986.

Rongcheng Swan National Nature Reserve

As one of the largest wintering places for swans in China, this reserve in Shandong Province mainly protects whooper swans (大天鹅), which make it different from other nature reserves. In 2007, it was changed into a national nature reserve. Now every year, thousands of whooper swans arrive here to spend the winter, making it an important resting and wintering place for themselves.

Sanya Coral Reef (珊瑚礁) National Marine Nature Reserve

This reserve focuses on protecting coral reefs and their living environment in Sanya City, Hainan Province. In 1990, it became a national nature reserve. This reserve is on the coast, so the area of the reserve has good water quality and many kinds of creatures,

5 . In the summer of 2021, an unseasonal event took place. More than 100 miles of Florida’s coast around Tampa Bay became an oxygen-depleted (缺氧的) zone containing dead fish along the nearby shoreline.

Much of the conversation around our climate crisis highlights the emission of greenhouse gases and their effect on warming, sea-level rise and ocean acidification (海洋酸化). We hear little about the effect of climate change on oxygen levels, particularly in oceans and lakes. But water without adequate oxygen cannot support life. For the three billion people who depend on coastal fisheries for income, declining ocean oxygen levels are devastating.

As ocean and atmospheric scientists focus on climate, we believe that oceanic oxygen levels are the next big victim of global warming. To stop the situation from worsening, we need to expand our attention to include the dangerous state of oceanic oxygen levels — the life-support system of our planet. We need to accelerate ocean-based climate solutions that boost oxygen. Examples include nature-based solutions such as those discussed at the 2021 United Nations Climate Change Conference (COP26) held in Glasgow.

Enhanced monitoring of oxygen and the establishment of an oxygen-accounting system are a must. Putting oxygen into the climate story motivates us to do the work to understand the deep systemic changes happening in our complex atmospheric and oceanic systems. We celebrated the return of humpback whales in recent years to an increasingly clean New York Harbor and Hudson River. However, dead fish blocked the Hudson in the summer as warmer waters carried less oxygen.

Ecosystem changes connected to physical and chemical system-level data may point the way to new approaches to climate solutions. It includes an enhanced understanding of the life-support system of our planet. Roughly 40 percent of the world’s people depend on the ocean for their livelihoods. If we do not save marine life from oxygen starvation, we starve ourselves.

C．To call for more attention to oxygen starvation in waters.

D．To show the achievements in reducing air pollution.

8 . 阅读下列短文, 在空白处填入1个适当的单词或括号内单词的正确形式。

Ar Horqin Grassland Nomadic System in the Inner Mongolia autonomous region, listed on the list of Globally Important Agricultural Heritage Systems by the United Nations,     1     (demonstrate) the wisdom of herdsmen to work in harmony with nature.

The     2     (season) movement of herds among different pastures (牧场) plays an important role in maintaining the self-renewal and recovery     3     (capable) of the grasslands. While keeping soil fertility from degrading, the nomadic lifestyle can protect vegetation and make good use of water resources,     4     the growing population of people and livestock, still puts much pressure     5     the grassland resources. Locals have, therefore, come up with ways to avoid overgrazing. With ancestral wisdom     6     (root) in a time of relatively small societies, it may be unable to solve issues today. This is     7     modern planning can help with.

For example, since 2015, under the guidance of the local government of Ar Horqin Banner, the number of sheep and goats in the nomadic system     8     (reduce) from 390,000 to 190,000, while the number of cattle has been increased from 40,000 to 81,000 head. No more than 100,000 sheep are allowed to migrate to the summer camps every year. With     9     (scientific) designed grazing patterns ensuring sustainable development of the grasslands, herdsmen can maintain     10     more balanced relationship with nature.
