1、流程图写作思路：时态一般，语态被动指明步骤，不能重复，用以下表达方式The starting/ beginning step is to And then/ followed by+ 动名词/ 名词/ being done /after thatIn / To the 3rd stageSubsequently = nextly = and thenFrom that onwardsAfterwards/ later Before completionTo finish the entire process =finally/ at last图中明确信息：，名次直接抄，动词一般改为被动（可替换
2、）隐藏信息：图形、图片要概括表述读不懂时用：goes to 地点； is sent to 地点；表加入：物品 is added in 步骤 to 表加工：is processed by 物品is dealt with by 物品五，并行步骤，用“同时”：At the same time, in the mean time, meanwhile,While, and simultaneously, in course of which开头段： Based on the procedural information exhibited in the flow chart, we can under
3、stand how/ the way + show 后名词变动词，用被动show 后名词加 is completed The flow chart explains the procedure in which sth is/ can be done.读不懂时用：be processed(被加工)，be produced(被制造)， operate（运行） ，work(运做)，function（运作） ，be made(大规模制造)。Example:According to the illustrational materials displayed were on the flow char
4、t, we can understand how the silkworms lifecycle is completed and the stages in which silk cloth is produced.In terms of the lifecycle, the first stage is for female moths lay/ produce eggs on mulberry leaves, which after 10 days hatch(孵化)/ turn into silkworm larvae/larvas. And the young mainly live
5、 on(以为主食) mulberry leaves for the next/another 4 to 6 weeks/ 28 to 42 days/ one to one and half month before starting to produce silk threads around them. Subsequently, it takes 3 to 8 days to make/ form a cocoon, in which a worm needs 16 days to matures into a moth. 表 在之前：before, by, 3 days ahead,
6、in advance在之后：after, in( 将来时 )， since（完成时） ，later(过去时，一般时) ，ago（过去时）it takes sb 时间 to do人/ 物 spend 时间 on doingWith regard to silk cloth production, the starting step is to select high-quality cocoons, which are then boiled in (high-temperature) water. To the 3rd stage, a thread with the length of 30
7、0 to 900 meters is unwinded from a processed(被加工过的) cocoon, 3 of which are twisted together in the following process to be dyed (with colors). To complete the entire procedure, silk cloth is woven, which can also be subject(=be processed by) to dying.As illustrated, the charts explain the life cycle
8、 of the silkworm and the stage in the production of silk cloth.Example:The illustrational material in the diagram is concerned with how a water clock is made.(结构图)Its basic structure consists of/ is made up of/ includes/ is composed of/ comprises a top plastic bottle taped attached to/ stuck to unde
9、rneath/ below the neck. In the lower part of the stand is another plastic bottle with its neck removed.The first step is to turn the tap on, allowing water to fill in/ enter the top bottle. Nextly, the hole is covered with a finger. To the 3rd stage, excess water overflows from the straw after the t
10、op bottle is filled, which is to ensure a constant water level. After that, the finger is moved away from the hole so/ in order that water can drip/ drop/ fall to the lower bottle. Subsequently, levels per minute are marked on the body surface. Finally, the lower bottle/ it is emptied and the proces
11、s is repeated for the reason/ purpose of timing.Example:24.The entire procedure is described in the flow chart how to remove salt from seawater to produce drinkable water.The beginning step is for seawater to the pre-treatment filter, some of which, as the filter backwash, is returned the sea, while
12、 the rest, in the second stage, is forced through membrane at high pressure, and in this process, impurities and salt are removed from water molecules, and in mean time, sea water concentrate also flows back to sea.Afterwards, the processed water goes to/ is sent to(for) the post-treatment lime、chlorine and fluoride. Before in enters the integrated water supply system, the drinkable water is stored/ kept in the storage.As illustrated, that is hoe + 抄题.
