3 .

A．The harm done by single-use plastics.

B．The topic for the woman’s composition.

C．Environmental issues.

D．Some recent hot news.

4 . Many of the negative impacts humans have on the environment are visible to the naked eye. Trash washes up on our beaches, the ice caps are visibly shrinking, and smog darkens our skies. But some environmental threat, such as microplastics, are nearly invisible.

The U. S. National Oceanic & Atmospheric Administration classifies microplastics as any piece of plastic less than five millimeters. Some are as small as three microns—half the size of a red blood cell. This comes from a variety of sources, including the microbeads found in cosmetics, paint, tire dust, industrial waste, and clothing.

These tiny fragments can become fixed in animals’ tissue through taking food or breathing. Various marine species, such as deposit-feeding lugworms, are shown to have microplastics in their intestinal tracts (肠道). The production and disposal of microplastics, among other unaware actions by humans, have played a significant role in boosting the worsening of marine ecosystems. But microplastics are not just a problem for marine life. Humans are consuming them too, sometimes through eating seafood containing microplastics.

Microplastics also run uncontrollably in drinking water. A 2017 investigation by Orb Media, which looked at tap water samples from over a dozen countries, found that 83 percent of the samples were contaminated with plastic fibers. Once taken, most of the microplastics stay in our systems forever, and little is known about their long term impact on our health.

Microplastic pollution is not an easy problem to deal with, but there are small changes that you can make to reduce your contribution to the problem. One strategy is to stop fibers before they enter the wastewater stream. Patagonia announced that it will sell the Guppy Friend, a bag that you can place clothing in before tossing it into the wash, which will prevent the fibers from being flushed away. You can also avoid buying any facial scrubs (面部磨砂膏) that use plastic microbeads. Lastly, you can reduce your plastic consumption and waste altogether by buying reusable water bottles and grocery bags, and being sure to always recycle any plastics you come across.

5 . For many people, it is hard to imagine what it is like to lose their sense of smell. Known as “anosmia”, loss of smell can have a substantial effect on our overall wellbeing and quality of life. But while a sudden respiratory infection (呼吸道感染) might lead to a temporary loss of this important sense, your sense of smell may well have been gradually eroding away for years due to something else- air pollution.

Exposure to PM2. 5 has previously been linked with smell loss, but typically only in occupational or industrial settings. But new research is now starting to reveal the true scale and the potential damage caused by the pollution we breathe in every day. On the underside of our brains lies the olfactory bulb (嗅球). This sensitive bit of tissue is essential for the enormously varied picture of the world we get from our sense of smell. It’s also our first line of defense against viruses and pollutants entering the brain. But, with repeated exposure to PM2. 5, these defenses slowly get worn down.

“Our data show there’s a 1.6 to 1.7-fold increased risk of developing anosmia with sustained particulate pollution (粒状物污染),” says Murugappan Ramanathan, a rhinologist. One Mexican study in 2006, which used strong coffee and orange odors showed that residents of Mexico City which often struggles with air pollution — tended to have a poorer sense of smell on average than people living in rural areas of the country.

So, should we care that air pollution to which we are all exposed -is damaging our sense of smell and causing anosmia? Clearly, the answer is yes. Ramanathan says, “Air quality matters. I think we need tight regulations and control. Many people may not even realize the pollution they are exposed to. But even the everyday, low level air pollution we are exposed to should be taken more seriously.”

1. What do the underlined words “eroding away” mean in paragraph 1?

A．Evolving.	B．Becoming weak.
C．Becoming sharp.	D．Appearing.

2. What can we infer from paragraph 2?

A．Exposure to PM2. 5 has nothing to do with smell loss.

B．The pollution we breathe in on a daily basis may cause harm.

C．Our nose stops viruses and pollutants from entering the brain.

D．Our defenses will disappear quickly with air pollution exposure.

3. What does the study reveal about people in Mexico City?

A．They have developed anosmia with air pollution.

B．Their sense of smell is poorer than rural people’s.

C．They often consume strong coffee.

D．They tend to have a good sense of smell.

4. What will the author probably talk about next?

A．How we should react to air pollution.

B．What we should do to protect the environment.

C．What steps we can take to recover from anosmia.

D．How we can improve our life quality.
