【正文】 mins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath. Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (腸) can. That discovery could help other researchers develop medicinecontaining gums that fight colds, ease headaches, battle nervousness, and more. Scientists might even create antimicrobial (抗菌的) gums that cure bad breath. Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake. Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes. The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use. For now, Stay Alert is available only to the military (軍隊). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.72.

Despite his disability, and his parents’ doubts, Ibrahim was determined to go to school. “When I was eight,” Ibrahim says, “other kids of my age were going to school while I stayed at home. I did not like that. So, I pestered（纏著） my parents until they finally let me go to school.” Ibrahim’s parents sent him to a private school nearby. Although the journey to and from school was a short one, it still wasn’t easy for Ibrahim. He had to use his hands to help him move along, protecting them with plastic slippers. But at least he was getting an education. However, after only a year in school, Ibrahim’s education was interrupted when his parents se
