问题     July 2019 was the hottest July on record; September 2019 was the hottest on record; January 2020 was the hottest on record; May 2020 was the hottest on record. This is not a coincidence. It is a pattern. Carbon dioxide, an important greenhouse gas contributing to global wanning, has increased by 9 percent since 2005 and by 31 percent since 1950. A U. N. Intergovernmental Panel on Climate Change special report pointed out that the world has already warmed about one degree Celsius from pre-industrial levels. It stressed the urgency to act to limit wanning to 1. 5 degrees, and that a two-degree increase will lead to unprecedented extreme heat, water scarcity and food shortages around the globe.
    In my own practice, I explain to patients how the climate crisis affects their health. For example, apart from contributing to global warming, rising carbon dioxide levels increase the amount of pollen that plants produce as a consequence of higher rates of photosynthesis. This rise in pollen levels can lead to worsening allergy symptoms. Another example is fine particulate matter (known as PM2. 5) associated with air pollution, much of it linked to the burning of fossil fuels that help drive the warming. When we breathe in these particles, they travel down the airway and settle in the tiny air sacs called alveoli of the lungs, causing inflammation and potentially worsening asthma symptoms. The explanations are simple, but the health risks are widespread and complex. Ground-level ozone pollution, which is worse in hotter weather, can also harm people with asthma and other respiratory diseases.
    And that harm falls disproportionately on the poor. Wealthier people living in North America have a per capita carbon footprint that is 25 percent higher than those of lower-income residents, with some affluent suburbs producing emissions 15 times higher than nearby neighborhoods. These carbon emissions contribute to global warming, and the subsequent health consequences are felt far beyond the neighborhood that produces them. Low-income communities are less resilient on average to the health impacts of climate change.
    The majority of Americans think global warming is happening. The climate crisis has unfairly been labeled as political, when in fact, people outside the US also recognize that something needs to be done about it. Even for those who are seemingly unaffected, there is increasing global recognition that all the safeguards of living in a protected community and affording expert medical care will eventually fail if global wanning continues unchecked.
    The only treatment is collective climate action in the present. It can be as simple as educating family and friends, while making sustainable shopping and traveling choices. It includes eating less meat, unplugging electronics and raising a voice against the fossil fuel industry. The climate crisis is a public health issue, and we must start healing the planet in order to heal each other. Fighting against the climate crisis is one of the most patriotic things we can do right now; it will protect our health and the health of our neighbors across the country and the globe, and will allow all of us to live on this planet, the only home we have.
What can we learn from Paragraph 4?
选项 A、Most Americans are indifferent to climate change.
B、The exacerbation of global warming threatens everyone.
C、Political factors are accountable for the current climate crisis.
D、There are still some areas unaffected by climate change.
答案B
解析 推断题。第四段主要讲大多数美国人都认为全球正在变暖，人类已经广泛认识到其后果，并且认为应该采取一定的措施，否则，就算目前条件优越的地方也会遭遇不幸，因此答案选[B]。[A][C]与文义相反；[D]文中没有提到。
