昆虫的英语知识点总结
昆虫的英语知识点总结Anatomy of InsectsInsects belong to the class Insecta within the phylum Arthropoda. They are characterized by their three body segments (head, thorax, and abdomen), three pairs of legs, and often one or two pairs of wings. The exoskeleton, made of chitin, provides protection and support for the insect's body.The head of an insect contains the sensory organs, including the eyes, antennae, and mouthparts. Insects have compound eyes, which consist of many individual units called ommatidia that can detect movement and light intensity. The antennae are used for detecting chemical signals, such as pheromones, and for sensing the environment. The mouthparts vary greatly among different insect species and are adapted for feeding on a wide range of substances, including nectar, blood, and plant materials.The thorax of an insect is where the legs and wings are attached. Insects have six jointed legs that are specialized for walking, jumping, digging, or swimming, depending on the species. Some insects, such as beetles, have modified front legs for grasping prey or digging. The wings of insects are also diverse, with some species having membranous wings, while others have hardened forewings (elytra) that serve as protective covers for the delicate hindwings.The abdomen of an insect is where the digestive, reproductive, and respiratory systems are located. The digestive system includes a foregut, midgut, and hindgut for processing food and absorbing nutrients. The reproductive system varies among different insect species, with some having internal fertilization and others having external fertilization. The respiratory system of insects consists of a network of tubes called tracheae that deliver oxygen directly to the tissues.Life Cycle of InsectsInsects undergo a process called metamorphosis, which involves a series of developmental stages from egg to adult. There are two main types of metamorphosis: gradual (incomplete) and complete.In gradual metamorphosis, the insect goes through three stages: egg, nymph, and adult. The nymphs resemble miniaturized adults and gradually grow in size and develop wings through a series of molts. This type of metamorphosis is common in insects such as grasshoppers, cockroaches, and dragonflies.In complete metamorphosis, the insect goes through four stages: egg, larva, pupa, and adult. The larvae are specialized for feeding and growing, often looking very different from the adults. After a period of feeding, the larvae enter the pupal stage, during which they undergo a radical transformation inside a protective case. The adults that emerge from thepupae are sexually mature and have wings for dispersal and reproduction. This type of metamorphosis is seen in insects such as butterflies, beetles, and flies.Ecological Significance of InsectsInsects play a critical role in ecosystems as pollinators, decomposers, and food sources for other organisms. Many plants rely on insects for pollination, with bees, butterflies, and flies being the primary pollinators of flowering plants. Without insects, many crops and wild plants would not be able to reproduce, leading to a decline in biodiversity and food availability.Insects also play a vital role in recycling nutrients through decomposition. They consume dead organic matter, such as fallen leaves and animal carcasses, and break it down into smaller particles that can be used by plants and other organisms. This process helps to maintain soil fertility and return nutrients to the ecosystem.Furthermore, insects are key components of food webs, serving as prey for birds, mammals, reptiles, and other insects. They are also important predators and parasites of other insects, helping to control pest populations and maintain ecological balance.In recent years, there has been growing concern about the decline of insect populations due to habitat destruction, pesticide use, and climate change. This decline threatens the stability of ecosystems and the services that insects provide, such as pollination and nutrient cycling. Conservation efforts are underway to protect and restore insect populations and their habitats to ensure the health of ecosystems and human well-being.In conclusion, insects are a diverse and ecologically significant group of animals that play a fundamental role in the functioning of ecosystems. Their unique anatomy, life cycle, and ecological interactions make them essential for pollination, nutrient cycling, and food web dynamics. Understanding and appreciating the value of insects is crucial for the conservation and sustainable management of our natural environment.。

Speaking of personal questions, there is an expression people sometimes use when their children ask, "where do babies come from?" Parents who discuss sex and reproduction say this is talking about the birds and the bees.
7、the birds and the bees:（对孩子解释的） 有关两性关系的基本常识，初步的性教育 。 8、mad as a hornet:像黄蜂样愤怒（意指非 常生气、愤怒，即暴跳如雷，怒不可遏） 9、 Stir up a hornet’s nest：相当于中文的 俗话: 捅了马蜂窝，惹了麻烦。 10、have butterflies in one’s stomach从字 面上来解释就是，一个人的胃里有蝴蝶。可是， 这个说法的真正意思是一种持续不断的恐惧、 紧张或忧虑的心情，和中文里说的“心里感到 七上八下”很相似。
tight作副词表“紧紧地”，bug指“小虫”。 “Sleep tight, and don’t let the bed bugs
bite.”面指“睡得紧紧地，别被床上的虫子咬 到。” 由于古时候床铺是用绳子（rope）搭成，须把绳 子绑紧才能睡得安稳，因此sleep tight指 “睡得香甜”。 tight也有“安稳地（soundly）”、“酣然地” 之意，故 sleep tight即指“睡得好”。 从前的确有小虫子会趁人在睡觉时爬到床上去咬 人，吸人血，因此这说法即“祝人一夜好眠”， 不会被小虫咬之意。
11、stop bugging me:别烦我。 12、put a bug in one’s ear ：事 先给某人暗示,提醒。 13、as snug as a bug in a rug ： 非常舒适地, 极其安逸地。
14、sleep tight -- don't let the bed bugs bite

2、a beehive of activity：忙碌的蜂 窝
3、make a beeline：径直去
4、the bee's knees：杰出，出类拔萃
5、a bee in her bonnet：bonnet 指的是古代外 国妇女带的一种宽沿圆形大帽子，有带子可以系在 脖子上，如果有蜜蜂飞进去是很难出来的。 a bee in one‘s bonnet 指的是头脑中的固执的念 头，而且往往是难以摆脱的异乎寻常的怪念头，经 常说： have a bee in one’s bonnet about sth 。 “He has a bee in his bonnet about constructing a yacht of his own design. 他脑 中一直有个想法，要自己设计构造一艘游艇。 6、that is none of your beeswax：不关你的事。
