Graph 2 shows improvements in life expectancy and infant mortality between 1970 and 1992. Life expectancy was just 60 in 1970 but rose to almost 72 in 1992. In contrast, the number of babies dying dropped dramatically, from 60 per 1000 in 1970 to only 22 in 1992.

The charts below show the percentage of their food budget the average family spent on restaurant meals in different years. The graph shows the number of meals eaten in fast food restaurants and sit-down restaurants.

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Where families eat their restaurant meals also changed during that 30-year period. In 1970, families ate the same number of meals at fast food and sit-down restaurants. In 1980, families ate slightly more frequently at sit-down restaurants. However, since 1990, fast food restaurants serve more meals to the families than do the sit-down restaurants. Most of the restaurant meals from 2000 were eaten at fast food restaurants. If this pattern continues, eventually the number of meals that families eat at fast food restaurants could double the number of meals they eat at sit-down restaurants.

二．臨界值

分析認(rèn)為，臨界值寫法屬于非主流寫法，但是卻是可以起到意想不到的好效果。所謂臨界值就是在變化趨勢較多的折線中從橫向或者縱向劃一條線，然后分別描寫上下的數(shù)據(jù)。

The main season for sales is in the December to May period. Sales were consistently above 200 million dirhams per month, rising sharply to a peak of 350 million dirhams in March. However, for the next four months, sales declined steadily, reaching an annual low of 120 million dirhams in July.

In August, there was a sudden increase. Sales almost doubled, rising from 120 million dirhams in July to 210 million dirhams in August. This was followed by a drop in September, back to the July figure.

From September to October, sales recovered, from 120 to 180 million. In October and November, sales remained steady, and there was a small increase in December to 190 million dirhams.

從圖中我們可以將縱軸中的200處劃條橫線，將數(shù)據(jù)上下分為2段，然后分別描述上方和下方的數(shù)據(jù)。
