英四成宜第七周小班课1.主要展示了同学们的词汇树，在作业中我也想展示一下我的词汇树。按照物种进化顺序排列了动物词汇树。左侧绿色框中是对应物种的运动方式，红色框中是对应物种的形容词，右侧橘色框中是对应物种的具体动物体现。主要体现的背词方式有2 种：*词缀构词，如单细胞生物，unicellular ，Uni-意为单一，一方，例Uni-cycle 独轮车， cellule意为小细胞，小室*词意构词，如蚯蚓，earthworm, 泥土与软体虫组合2.价值在句子中的体现*体现在语音上， 强调突出哪个词，该词发音就会与其他词区别开来，也就是其在句子中的价值较大*体现在句意上， 写作时运用一些语法方法或位置的摆放，如下列这一组句子，大致意思相同，但突出强调的点不同1.the sweater of heavy wool kept me warm 2.because the sweater was made of heavy wool,it kept me warm 3.the sweater kept me warm,for it was made of heavy wool 4.being made of heavy wool,the sweater kept me warm 5.the sweater,which was made of heavy wool,kept me warm unicellular animalcoelenterate(腔肠)annelid(扁形)arthropod(环节)echinoderm(节肢)vertebrate(脊椎)fishamphibian(两栖)reptile(爬行)mammalbirdBlood fluck earthworm shrimp,lobster,crab,starfish,spider,mosquito,fly,bee tuna,salmon,sardine,carp,shark tadpole,frog,toad,giant salamander tortoise,turtle,snake,lizard,crockdile,wall lizard, Wriggle,creep, crawl,scramble Soar,swoop,glide,circle Hummingbird,ostrich,seagull,sparrow,swan,owl,eagle,nightingale,penguin,woodpecker,peacock,swallow,goose,wild groose giraffe(),gorilla,chimpanzee,zebra,rhinoceros,weasel,koala,kangaroo,hedgehog, hippo,dolphin,buffalo,whale leopard,alpaca,ass,bull,antilope,reindeer,squirrel,marmot,mule fluffy Furry,carnivorous,herbivorous,omnivorous,fierce, Scaly,
