Earwax
Experts say earwax protects and cleans the ear. / It traps dirt and other matter and keeps insects out. / Doctors think it might also help protect against infections. / Earwax is normally expelled and it falls out of the ear or gets washed away. / But extra wax can harden and form a blockage / that interferes with sound waves and reduces hearing. / People can also cause a blockage when they try to clean out their ears, / but only push the wax deeper inside. / Earwax removal is sometimes necessary. / But you have to use a safe method or you could do a lot of damage. /
解析
耳垢
专家说,耳垢可以保护耳朵并使耳朵保持清洁,它能阻挡尘埃和其他物体,并防止昆虫进入。医生认为,耳垢还可以帮助预防感染。耳垢一般能从耳朵中排出,但耳垢过多会变硬,甚至堵塞耳道,影响听力。另外,人们在清洁耳垢时也可能会引起耳道堵塞,因此我们要用安全的方法清理耳垢,否则会对耳朵造成许多伤害。
