The given graph indicates the procedures of glass bottle recycle by three main stages.
According to the table, various glass bottles are gathered in the collecting site and then transported to the cleaning station at the very beginning. Then it comes to the second stage where the bottles are washed by the high pressured water, after which they are categorized into Brown, Green as well as clear groups based on their color. After that, bottles are delivered to the recycling plant where the prepared bottles are burned in furnace with high temperature into liquid glass for recycle. Next, the recycled liquid glass along with new liquid glass is shaped into bottles again through glass moulds. Finally, the newly produced glass bottles are launched into the customer supermarket, till this point, the process of glass recycle is finished completely.
In summary, it is obvious that stage 2 is the most crucial and complex one during the whole recycling process.

The given table reveals how the water collecting set functions to gather water in the wild.
At the very beginning, in order to prepare the set, it is necessary to find a hole on the ground which can receive sufficient sunshine and abound with plenty of green plants. Then a container used to collect water is placed in the center of the hole, and the hole is covered by a plastic sheet, fixed by stones on the edge. However, it is recommended to place a suitable stone in the middle of the sheet to ensure its lower position exactly above the water container.
When the sun shines above the green plants, plants will generate water vapor owing to the photosynthesis, and the water vapor is condensed into water drops on the plastic sheet. Under the effect of gravity, the water drops increasingly gather in the lower point and fall into the container placed under the plastic sheet.

The curve graph reveals the international water consumption during the entire 20th century, and water usage in Brazil as well as Congo in 20## is illustrated in the second chart.
According to the line chart, the global water used in agriculture(500 km³) considerably outweighed that in industry (50 km³) and household(20 km³) section were, and they lead a similarly slight increase in the first 50 years. However, since 1950, the agricultural water consumption witnessed a constantly dramatic rise, reaching the peak at exactly 3000 km³in 2000. On the other hand, industrial and domestic water usage rose moderately in the second half century, peaking at around 1300 and 400 km³respectively. In the second chart, we can clearly find that the water use of each person(359 m³) of Brazil in 2000, which possessed 176 million inhabitants and 26,500㎡irrigating lands, intensively surpassed that of Congo (8 m³), with only 5.2 million dwellers and 100㎡irrigating lands.
In summary, the water worldwide was mainly consumed by agriculture field during the given 100 years, and Brazil’s average individual substantially overweighed that of Congo in 2000.

As can be seen from the chart, the consumption of beef stood the largest in 1979 with the data of around 220 grams for each person every week. However, after a fluctuation between 1979 and 1988, it dropped dramatically to the bottom at approximately 100 grams in 2004. Similarly, the lamb also declined constantly in the same period, ending up with about 60 grams in 2004. However, the figure of chicken experienced a significant rise from 140 grams in 1979 to over 250 grams in around 2002, which leveled off to exactly 250 grams in the end. As to the fish consumption, the figure maintained a long-term slight decrease tendency in the whole stage, remaining the least popular food option among the four.
In conclusion, the chicken consumption witnessed a staggering increasing whilst other meats decreased to a certain degree in the given period.

The graph describes data about the subway systems in London, Paris, Tokyo, Washington DC, Kyoto and Los Angeles.
According to the table, London railway possesses the longest history among the six cities, which was opened in 19th century (1863), while that of Los Angeles was opened in the 21st century (2001), also the latest one. The other four underground systems were all built in 20 century. In terms of kilometers of route, London subway holds the first place with the length of 394km. The length of subway in Paris, Tokyo as well as Washington DC is between 100 and 200 kilometers. However, that of Kyoto and Los Angeles isbelow 100 kilometers, with Kyoto the shortest (only 11 kilometers). When it comes to the annual passenger transporting capability, Tokyo and Parisexceeds 1000 million, especially Tokyo the largest (1927 million), while Los Angeles and Kyoto transport fewer than 100 million per year, 50 and 45 million respectively. The number of the rest two cities lies between 100 and 1000 million.
In conclusion, London railway ranks the first in terms of opening date and route length whereas Kyoto the least in route length as well as annual passenger transporting.
