The first diagram vividly reveals the basic four stage

6、s of the life of a silkworm. First of all, eggs are laid by moths, and after ten days each egg grows up into a silkworm larva that feeds on mulberry leaves. This stage lasts for up to six weeks until the larva starts to weave (spin) a cocoon of silk thread around itself. After a period of about thre

7、e weeks, the fully-developed moths eventually break out of the cocoon, which also means the beginning of a new life cycle. Cocoons are the raw material for the production of silk cloth. However, not all cocoons are qualified to make silk cloth, so they are selected first. Then, these cocoons are boi

8、led in water in order to be able to be unwound in the following stage. After this, the threads, which are 300 to 900 metres long, are twisted together. Finally, the twisted threads are woven before being dyed or dyed directly. Overall, the two diagrams present the life journey of a silkworm and the

9、procedures of making silk cloth. 【知识模块】 小作文（看图作文） 2 【正确答案】 There are two diagrams which illustrate the cement producing process and how concrete is made using cement. The production of cement consists of four main stages. To start with, limestone and clay are poured into a crusher where they are gro

10、und into powder. The resulting powder is then put through a mixer and then into a clockwise rotating heater. After heating, the powder can be ground into cement by grinder. Finally, the cement is packed up in bags. Compared with the making process of cement, the production of concrete is relatively

11、easy. 15% of cement, 10% of water, 25% of sand and 50% of gravel, which means small stones, are poured into a concrete mixer; then the mixer starts to rotate clockwise constantly to make sure these four materials can be mixed evenly before they are used for building purposes. Overall, these two diag

12、rams together present how natural materials are transformed into cement, men furthermore to become concrete. 【知识模块】 小作文（看图作文） 3 【正确答 案】 The pie chart shows that there are four main causes of farmland becoming degraded in the world today. Globally, 65% of degradation is caused by too much animal graz

13、ing and tree clearance, constituting 35% and 30% respectively. A further 28% of global degradation is due to over-cultivation of crops. Other causes account for only 7% collectively. These causes affected different regions differently in the 1990s, with Europe having as much as 9.8% of degradation d

14、ue to deforestation, while the impact of this on Oceania and North America was minimal, with only 1.7% and 0.2% of land affected respectively. Europe, with the highest overall percentage of land degraded (23%), also suffered from over-cultivation (7.7%) and over-grazing (5.5%). In contrast, Oceania

15、had 13% of degraded farmland and this was mainly due to over-grazing (11.3%). North America had a lower proportion of degraded land at only 5%, and the main causes of this were over-cultivation (3.3%) and, to a lesser extent, overgrazing (1.5%). Overall, it is clear that Europe suffered more from fa

16、rmland degradation than the other regions, and the main causes there were deforestation and over-cultivation. 【知识模块】 小作文（看图作文） 4 【正确答案】 The two tables contain sales data for Fairtrade coffee and bananas in 1999 and 2004 in five nations of Europe. The first table shows low-level coffee sales increasi

17、ng in all five countries, albeit to widely varying degrees. In two places sales increased by the same small amount: 1.8-2 million euros in Denmark, and 0.8-1 million in Sweden. The increment was slightly larger in Belgium, from 1-1.7 million euros. Meanwhile, in Switzerland sales doubled from 3-6 mi

18、llion euros. Finally, in the UK there was an enormous increase, from 1.5-20 million euros. In the second table, it is Switzerland which stands out as buying far more Fairtrade bananas than the other four countries. Swiss sales figures jumped from 15 47 million euros across these five years, while in

19、 the UK and Belgium sales only grew form 1-5.5 and from 0.6-4 million euros respectively. Sweden and Denmark showed a different pattern, with falls in banana sales from 1.8-1 and 2-0.9 million euros. Comparing the two tables, it is clear that in 1999 Fairtrade coffee sales ranged from 0.8-3 million

20、euros in these five countries, while banana sales also mostly clustered between 0.6 and 2 million euros, with Switzerland the outlier at a huge 15 million euros. By 2004, sales figures for both products had risen across the board, except for Sweden and Denmark which recorded drops in banana sales. 【知识模块】 小作文（看图作文）
