2025年中考英语阅读理解练习题科技类说明文

Microplastics: Bad for Our Health

Nowadays, microplastics are becoming a big problem for our health. Microplastics are very small pieces of plastic. They are smaller than 5 millimeters. These tiny plastics are everywhere. We can find them in the air we breathe, the food we eat, and the water we drink.

A study in a famous medical magazine shows that microplastics can get into our bodies. Once inside, they can stay in our arteries (the tubes that carry blood). This may make us more likely to get sick. For example, it can increase the risk of heart problems and strokes. Italian scientists studied 257 patients who had operations to clean their blood vessels. They found microplastics in the artery of 150 patients. After three years, 20% of these patients had a heart attack, a stroke, or died. But only 8% of patients without microplastics had these problems. Also, people with microplastics in their blood got more inflammation, which can make heart problems worse.

Another report tells us that microplastics can cause other health problems. They may lead to problems with having babies and make our breathing bad. Microplastics can even change our body in a way that might cause cancer in our stomach and intestines. Scientists have found microplastics in many parts of our body, like our poop, blood, lungs, breast milk, and even in a mother’s placenta. We get microplastics in our bodies by eating dirty food, drinking polluted water, breathing in dirty air, or touching plastics.

A study from the University of New Mexico found microplastics in our brain, kidneys, and liver. There are the most microplastics in our brain. The longer time goes by, the more microplastics we have in our body. And too many microplastics may make us more likely to get dementia.

We still don’t know everything about how microplastics hurt us. But what we know now is enough to tell us to be careful. Scientists need to do more research to learn all the ways microplastics are bad for our health.
