答案 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. /
