题文

Most schools forbid chewing gum(嚼口香糖), but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores. This exciting rearch is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from rious dias to bad breath. Other rearchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s becau the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (肠) can. That discovery could help other rearchers develop medicine-containing gums that fight colds, ea headaches, battle nervousness, and more. Scientists might even create anti-microbial (抗菌的) gums that cure bad breath. Tho 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. Rearchers have produced a gum called Stay alert.

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. Tho qualities make it easy for soldiers to u. For now, Stay alert is available only to the military (军队). The manufacturer may one day offer it for sale to the public.
