最美av女优

流程图,你怕不怕?!

加拿大这边屡次出现流程图,学生深受其苦

是时候给大家写点流程图作品了

今天奉上的两篇,都是动物生命周期图

这种图有一定的固定词汇和写作套路,请同学们模仿

图一:三文鱼The diagram below shows the life cycle of a salmon,from egg to adult fish.The diagram illustrates the various stages in the life cycle of the salmon. Overall, eight distinct stages/phases can be identified, beginning with spawning and ending in the adults’ migration to freshwater. The life of a salmon begins in a freshwater environment, such as a river, where the female lays a large number of eggs, a process know as spawning. After an incubation period, the eggs hatch and baby salmon, or fry, emerge. The salmon fry stay in the river until they grow bigger, ready to migrate to the estuary, the mouth of the river where freshwater and saltwater mix. Whenthe young/juvenile salmon are adapted to the salinity of seawater, they swim out into the ocean. In their rearing areas the salmon continue to grow and finally reach maturity. The adult salmon then swim back to their spawning locations in the river, where the cycle of life begins again. In summary, the diagram shows that the salmon goes through two distinct environments in the process of life, first as hatchlings and fry in freshwater and then as juveniles and adults in seawater.

Overall, six distinct stages/phases can be identified, beginning with mating and culminating in a mature frog. After mating, the female lays a cluster of eggs, or frogspawn, in water, which often sticks to submerged plants. After an incubation period, a small tadpole emerges from the egg. The tadpole is a limbless creature with a long tail for swimming. The tadpole then undergoes a series of changes before it grows into a mature frog. First, two legs begin to emerge at the base of the tail, eventually growing into very powerful hind legs. Then appear two front legs. As the four limbs develop, it begins to lose its tail. At this point the tadpole has transformed into a young frog. Once the frog reaches maturity, characterized by a larger body and the presence of blacks spots on its skin, it is ready for life on land. (175 words, band 8.5)
