　　The three pie charts give information about the average proportions of three kinds of unhealthy ingredients consumed by American population when having meals.

　　The consumption of sodium is largest in dinner, occupying 43% of the total intake, followed by lunch, providing 29% of this type of nutrient. The remainder can be found in snacks and breakfast ( each taking up 14%). Dinner is also loaded with saturated fat (37%), while 26% of it is taken in during lunch. The amount of the fat is relatively small in snacks and breakfast, accounting for 21% and 16% respectively.

　　However, people ingest highest level of added sugar when having snacks, making up 42% of overall sugar consumption, while the figure for dinner is just over 20%. In comparison with dinner, lunch contains slightly lower proportion of the sugar, and people only take in 16% of it during breakfast.

　　Overall, both sodium and saturated fat intake are greatest in dinner, while added sugar content is highest in snacks. On the contrary, the consumption of these nutrients is smallest in breakfast. (177 words)

　　The graphs provide a breakdown about the export incomes as well as its change in five categories between 2015 and 2016.

　　It can be revealed in the charts that three categories which are petroleum products, engineered goods and textiles showed an obvious growth. As the top two profitable trade commodities, the value of petroleum products and engineered goods increased from 61 and 58 to approximately 62 billion dollars, respectively. Whereas textiles, the merchandise with the lowest proceeds, experienced the biggest increase from 26 to 32 billion, changing by 15.24%.

　　By contrast, the other types of exports illustrated a different trend in these two years. The trade of gems and jewellery declined from 42 to 40 billion, whereas agricultural products stayed almost the same, with just a 0.81% rise.

　　To sum up, the gems and jewellery was the only category whose export value reduced. And the textile witnessed the biggest change in both export percentage and income. (158 words)

　　The flow chart illustrates the equipment and stages in electricity production in a hydroelectric power plant.

　　Overall, two reservoirs, bifunctional turbines and an electricity generator are mainly involved and converse operations are carried out during day and night.

　　With a dam established, the water from a local river is stored in the high-level reservoir, whose intake is opened during the day. Running down a slope, the torrential water becomes powerful enough to drive the rotation of the turbines at the bottom. Automatically, they operate the generator with the same central axis to produce electricity, which is then transmitted to the national grid through power lines. In the meantime, the water flows into the reservoir at the lower level.

　　In contrast, at night, the intake of the upper reservoir is closed and the turbines function as pumps to propel the water in the lower reservoir to run through the same channel but in the opposite direction back to the upper one for the use during the next day. (167 words)

　　The maps show the changes that have taken place at Grange Park since its construction in 1920.

　　In 1920, Grange Park could be accessed by the entrances close to Arnold Avenue and Eldon street. There were three Rose gardens and seats scattering around the edges of the park. A fountain was laid in the middle of the park, and to the west of the fountain was a stage for musicians. Areas designated for water plants (pond) and indoor plants (glasshouse) were in the northeastern and southeastern part of the park.

　　Today, an entrance has been added so that this place can be accessed from underground car park. Two of the rose gardens are merged and built on the place of the fountain, with seats surrounded, but the one in the north remains. The previous stage has been transformed into a theatre, namely Amphitheatre, used to host concerts. Finally, the plant areas has been demolished to make way for a play area for children, a café and a water feature.

　　Overall, Grange Park has undergone dramatic changes: rose gardens are relocated and several recreational areas are added and updated. (188 words)
