When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo’ s parents set out to prove the doctors wrong.
    The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren’t interested in supporting research into such a rare disease.
    However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial anderror(反复试验)，they finally created a cure from ingredients(调料) commonly found in the kitchen. The cure，named “Lorenzo's Oil”，saved the boy’s life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it.
    Finally，the boy’s father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy.

    Do you know how to use a mobile phone(手机) without being rude to the people around you?
    Talking during a performance irritates(激怒) people. If you are expecting an emergency call, sit near the exit doors and set your phone to vibrate(振动). When your mobile phone vibrates, you can leave quietly and let the others enjoy the performance.
    Think twice before using mobile phones in elevators, museums, churches or other indoor public places—especially enclosed spaces. Would you want to listen to someone's conversation in these places? Worse yet, how would you feel if a mobile phone rang suddenly during a funeral! It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off.
    When eating at a restaurant with friends, don’t place your mobile phone on the table. This conveys the message that your phone calls are more important than those around you.
    Mobile phones have sensitive microphones that allow you to speak at the volume you would on a regular phone. This enables you to speak quietly so that others won't hear the details of your conversations. If you are calling from a noisy area, use your hand to direct your voice into the microphone.
    Many people believe that they can’t live without their mobile phone. Owning a mobile phone definitely makes life more convenient, but limit your conversations to urgent ones and save the personal calls until you are at home.
