【英语时差8,16】昆虫也遵循万有引力定律？

 It’s such a common sight, you probably don’t think twice. You swat at the fly buzzing around your head, and it seeks refuge on the ceiling. You stomp¹ at an ant crawling along the baseboard, and it escapes by climbing the wall. Insects seem to respect the law of gravity about as much as someone with diplomatic immunity² respects a local jaywalking ordinance³. How Do They Get Away With It? Actually, flies and ants need to obey the same law of gravity that we do. The gravitational tug⁴ anything feels is directly proportional to its weight though. Because household insects weigh so much less than we do, it takes only a very small amount of force to overcome gravity and keep them stuck to the wall or ceiling. This force is easily provided by special structures on the tips of the insect’s legs, called the tarsi. On the tip of each leg, every fly has a tiny set of claws, which you can see with a magnifying glass.
