put together they weigh roughly the same as all of mankind. they also live nearly everywhere, except on frozen mountain tops and around the poles. for animals their size, ants have been astonishingly successful, largely due to their wonderful social behavior. in colonies(群體)that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. even more amazing is how they achieve this level of organization. where we use sound and sight to communicate, ants depend primarily on pheromones(外激素), chemicals sent out by individuals and smelled or tasted by fellow members of their colony. when an ant finds food, it produces a pheromone that will lead others straight to where the food is. when an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. in fact, when it comes to the art of war, ants have no equal. they are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. behaving in this selfless and devoted manner, these little creatures have survived on earth for more than 140 million years, far longer than dinosaurs. because they think as one, they have a collective(集體的)intelligence greater than you would expect from its individual parts.1.we can learn from the passage that ants are.a.not willing

1/10 of an acre in los angeles, loe and her family grow, can(裝罐)and preserve much of the food they consume. loe is a master food preserver, gardener and canning expert. she also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control whats on their plate. loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “i got into cooking my own food and started growing my own herbs(香草)and foods for that fresh flavor, ”she said. engineer by day, loe learned cooking at night school. she ultimately purchased a small piece of land with her husband and began growing their own foods. “i teach people how to live farm-fresh without a farm, ”loe said. through her website loe emphasizes that“anybody can do this anywhere. ”got an apartment with a balcony(陽臺)?plant some herbs. a window?perfect spot for growing. start with herbs, she recommends, because“theyre very forgiving. ”just a little of the herbs“can take your regular cooking to a whole new level, ”she added. “i think its a great place to start. ”then?try growing something from a seed, she said, like a tomato or some tea. canning is a natural extension of the planting she does. with every planted food, loe noted, theres a moment when its bursting with its absolute peak flavor. “i try and keep it in a time capsule in a canning jar, ”loe said. “canning for me is about knowing whats in your food, knowing where it comes from. ”in addition to being more in touch with the food shes eating, another joy comes from passing this knowledge and this desire for good food to her children:“influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture, ”she said, “that if we dont take care of the earth, no one will. ”5.the underlined word“prerequisite”(para.1)is closest in meaning to“”.a.recipeb.substitutec.requirementd.challenge6.why does loe suggest starting with herbs?a.they are used daily.b.they are easy to grow.c.they can grow very tall.d.they can be eaten

with foods.d.the responsibility to protect our earth.答案5.c6.b7.a8.dclife in the cleartransparent animals let light pass through their bodies the same way light passes through a window. these animals typically live between the surface of the ocean and a depth of about 3,300 feetas far as most light can reach. most of them are extremely delicate and can be damaged by a simple touch. sonke johnsen, a scientist in biology, says, “these animals live through their life alone. they never touch anything unless theyre eating it, or unless something is eating them. ”and they are as clear as glass. how does an animal become see-through? its trickier than you might think. the objects around you are visible because they interact with light. light typically travels in a straight line. but some materials slow and scatter(散射) light, bouncing it away from its original path. others absorb light, stopping it dead in its tracks. both scattering and absorption make an object look different from other objects around it, so you can see it easily. but a transparent object doesnt absorb or scatter light, at least not very much. light can pass through it without bending or stopping. that means a transparent object doesnt look very different from the surrounding air or water. you dont see ityou see the things behind it. to become transparent, an animal needs to keep its body from absorbing or scattering light. living materials can stop light because they contain pigments(色素) that absorb specific colors of light. but a transparent animal doesnt have pigments, so its tissues wont absorb light. according to johnsen, avoiding absorption is actually easy. the real challenge is preventing light from scattering. animals are built of many different materialsskin, fat, and moreand light moves through each at a different speed. every time light moves into a material with a new speed, it bends and scatters. transparent animals use different tricks to fight scattering. some animals are simply very small or extremely flat. without much tissue to scatter light, it is easier to be see-through. others build a large, clear mass of non-l
