Ocean water evaporates, falls as rain, and eventually runs back into the oceans again.Beginning at the evaporation stage, we can see that 80% of water vapour in the air comes from the oceans. Heat from the sun causes water to evaporate, and water vapour condenses to form clouds. At the second stage, labelled precipitation on the diagram, water falls as rain or snow.At the third stage in the cycle, rainwater may take various paths. Some of it may fall into lakes or return to the oceans via surface runoff. Otherwise, rainwater may filter through the ground, reaching the impervious layer of the earth. Salt water intrusion is shown to take place just before groundwater passes into the oceans to complete the cycle.,10,要点总结,流程图以描述为主，比较较少需要表达图中出现的所有信息时态比较单一，基本使用一般现在时结尾一般表示该流程总共分几步,11,生物生长图写作要点,多涉及时间的叙述，表达方式有：It takes + 时间 + to doThis stage lasts for After/During a period of 最后一个阶段里毛毛虫caterpillar变成蛹pupa，通常持续两小时。,12,单词使用,大多数单词都是不及物动词，所以多使用主动语态。grow, hatch, emerge, take place, occur, start, begin 等固定词组搭配distinct stages grow to maturity the cycle starts anew紧接着第二阶段会持续两三周，每个卵里面的胚胎embryo会发育成一个毛毛虫。,13,范文解析,14,15,流程图模板,The flow chart/ diagram shows/ illustrates the process/ procedures of how 从句In the first phase/ Firstly In the second phase/ after that/ and thenIt is followed by Before / after Thirdly In the final stage,16,流程图常用开头+过渡,The following diagraph shows the structure of.

During the fermenting process, the beans turn brown.Next, the brown beans are spread in the sun to dry. They are then put in large sacks and transported by train or lorry to a chocolate factory where they are roasted in an oven at temperatures of between 250 and 350 degree Celsius.After being roasted, the beans are crushed and the outer shell is removed. This part is not needed for making chocolate.

To be more precise, the vast expanse of farm and woods in 1780 reduced dramatically to 1860, followed with a disappearance in 2000. However, an environment friendly place, namely wetland for birds came up in 2000, at the end of villager river.In contrast, man-made constructions witnessed a prosperous development during the more than 2 centuries. Specifically, a bridge, a road and 200 homes were built until 1860, on the base of only 100 homes in 1780, which transformed into 2 roads, 500 houses, newly-built sports fields and schools, along with several shops at the river bank in the year 2000.Overall, Kelsbey experienced a diminish of nature areas as well as a prosperity of man-made building and facilities over the more than two centuries period.,25,The first potential location (S1)is outside the town itself and is sited just off the main road to the town of Hindon, lying 12 kms to the north-west. This site is in the countryside and so would be able to accommodate a lot of car parking. This would make it accessible to shoppers from both Hindon and Garlson who could travel by car. As it is also close to the railway line linking the two towns to Cransdon(25 km to the south-east), a potentially large number of shoppers would also be able to travel by train.,26,
