Everybody loves the swimming pool. But how clean is the water in the average backyard or public pool? If you trust chlorine to take care of germs, you’re in for a surprise.
Chlorine and other disinfectants do indeed help to clean the water, but some germs can survive in even the best-kept pool. For example, cryptosporidium may live in pool water for several days. Crypto causes a diarrhea illness and may rinse off the bodies of infected people or diapered children into the pool. If you swallow infected pool water, you may become sick.
Other germs may live for a few minutes or a few hours in a chlorinated pool: Giardia, Shigella, and E. Coli may cause diarrhea illnesses. Pseudomonas Aeruginosa may cause an ear infection called swimmer’s ear and also a skin infection called "hot tub rash", that is usually associated with very warm pools and spas.
选项
A、Chlorine and other disinfectants can be useful to clean the water.
B、You may become sick if you swallow infected pool water.
C、Some germs may live for a few minutes or a few hours in a chlorinated pool.
D、Few germs can survive in the best-kept pool.
答案
D
解析
本题考查的是考生对细节的理解。a、b、c三个选项文中都有所提及,而d项所提(在维持得很干净的泳池中没有细菌)正好与文意相左,故选d项。
