  剑八 TEST 1 The pie chart below shows the main reasons why agricultural land becomes less productive. The table shows how these causes affected three regions of the world during the 1990s.

  Task 2 Some people think that parents should teach children how to be good members of society. Others, however, believe that school is the place to learn this. Discuss both these views and give your own opinion. The pie chart shows how farmland is degraded globally. According to the chart, overgrazing was the leading cause of land degradation worldwide, accounting for 35%. This is followed by deforestation, at 30%. Another important reason why land becomes less productive is over-cultivation, which is responsible for 28% of the total degraded land. The remainder (7%) is caused by other reasons. The table compares the percentage of land degraded and the various reasons for degradation in three regions, namely North America, Europe and Oceania, during the 1990s. Of the three regions, Europe was the most seriously affected, with 23% of its agricultural land being degraded. This figure was higher than the percentages for North America and Oceania combined. In Europe, land clearance accounted for 9.8% of total degradation, whereas this only affected 0.2% of land in North America and 1.7% in Oceania. Europe also suffered from over-cultivation and overgrazing, at 7.7% and 5.5%, respectively. In contrast, Oceania has 13% of degraded land, and this was mainly caused by over-grazing (11.3%). The least affected region was North America, where only 5% of land was degraded, mainly due to over-cultivation (3.3%) and overgrazing (1.5%). In summary, overgrazing is the most serious threat to farmland worldwide and Europe was the biggest victim of land degradation in the 1990s. TEST 2 You should spend about 20 minutes in this task.

Insurance, which only accounted for 2% in 1981, rose fourfold to reach 8% by 2001. On the other hand, other workers? pay fell from 28% to 15% of total spending in the same time frame. Although there was an increase in expenditure on resources such as books, which grew from 15% to 20% between 1981 and 1991, this figure dropped steeply to 9% by 2001.
