在第一個主體段中，作者先從最長的紅色柱形入手，見劃線句子。然后在第二個主體段中繼續(xù)描寫藍色柱形的數(shù)據(jù)。在句型選擇上我們發(fā)現(xiàn)2段首句都使用了主系表的簡單句，選擇的主語也是類似，因此從高分角度來講，我們可以將第2個主體段首句的主語換成原先的表語，即31歲至50歲年齡組，效果會更好。

此外，我們還可以從描寫柱形的整體趨勢作為突破口，如：

You should spend about 20 minutes on this task.

The table below shows the figures for imprisonment in five countries between 1930 and 1980. Write a report for a university, lecturer describing the information shown below. You should write at least 150 words.

The bar graph shows that the figures for imprisonment in the five countries mentioned indicate no overall pattern of increase or decrease. In fact there is considerable fluctuation from country to country.

In Great Britain the numbers in prison have increased steadily from 30 000 in 1930 to 80,000 in 1980. On the other hand in Australia, and particularly in New Zealand the numbers fell markedly from 1930 to 1940. Since then they have increased gradually, apart from in 1980 when the numbers in prison in New Zealand fell by about 30,000 from the 1970 total. Canada is the only country in which the numbers in prison have decreased over the period 1930 to 1980, although there have been fluctuations in this trend. The figures for the United States indicate the greatest number of prisoners compared to the other four countries but population size needs to be taken into account in this analysis.

The prison population in the United States increased rapidly from 1970 to 1980 and this must be a worrying trend.

從圖中我們發(fā)現(xiàn)，每個國家的數(shù)據(jù)變化都是不同的，有升有降，沒有一個有規(guī)律的總體趨勢，這時候，我們可以用劃線句子的寫法在一開始就描述數(shù)據(jù)的總體情況。接下來再分國家逐一描述即可。

二、橫軸為地點，交通工具等其他專有名詞：

遇到這樣的情況，不管柱形有幾根，建議考生都可以按照長度從長寫到短，也可以先以描述總體趨勢作為突破口，如以下這個圖：

The graph above show information of employment rates across 6 countries in 1995 and 2005.

Summarize the information by choosing and describe the main idea, and make comparisons where appropriate.

The graph shows changes in employment rates in six countries between 1995 and 2005, for men and women. Overall more and more people of working age are employed, and there have been significant improvements for women, although they leg behind men in entering the workforce.

The most obvious trend in the graph is that women have lower employment rates in most of the countries in the graph. For example, in Australia in 1995, 57 percent of men could find work or retain a job, but only 27 percent of women. The difference was even bigger in New Zealand, with 60 percent of women. Even in Switzerland and Iceland, alightly more men than women were in the job market.

The second biggest trend in the graph is the improvement in employment between 1995 and 2005. In all countries shown, figures for both men and women improved. The biggest change was in the United Kingdom, from 55 percent of men in 1995 to 73 percent over the ten years period.

Furthermore, the increases in employment rates for women were much higher in New Zealand. The percentage of working women jumped from 25 percent to 42 percent, and in the United States from 45 percent to 61 percent over the decade.

In conclusion, all the countries in the graph showed at least a 12 percent increase in employment rates of both men and women over the ten yeares. While men had relatively higher employment rate throughout the period, more and more women appear to be entering the labour market.

在這幅圖里，經(jīng)過觀察，我們首先發(fā)現(xiàn)了一個總體趨勢，即婦女就業(yè)率盡管總體仍舊低于男性，但是情況正在好轉，所有國家的婦女就業(yè)率都有顯著的上升。因此，我們可以抓住這個總趨勢，在一上來就進行描寫。見第一段的劃線句子。但是經(jīng)過進一步觀察分析，我們又發(fā)現(xiàn)2個趨勢：一個是2005年婦女的就業(yè)率不論在哪個國家都要高于1995年同期的數(shù)據(jù)；另外一個是婦女的就業(yè)率在所有國家不管在哪一年都要明顯低于男性的就業(yè)率。這2個趨勢的發(fā)現(xiàn)，實際上可以作為2個分趨勢，可以分別作為主體段開頭的數(shù)據(jù)描寫突破口。見后2段的劃線句子。

我們再來看一個例子：

The chart shows the number of mobile phones and landlines per 100 people in selected countries. Write a report for a university lecturer describing the information given.

The graph shows the number of mobile phones and landlines per 100 users, for selected countries. Overall, most of the countries included in the graph have more mobile phones subscribers than landlines.

Most European countries have high mobile phone use. The biggest users of mobile phones are the Italians, with 88 cell phones per 100 people. For example, Italy has twice as many mobile phones as landlines, with 88 mobiles per hundred people compared to 45 for landlines. Mobile phone use is low in Canada, with fewer than 40 phones per 100 people. Denmark is also unusual because it has slightly more landlines than mobile phones.

However, in some countries, the number of landlines is higher than the number of mobile phones. One example is the USA, where the number of mobiles, at 50 per 100 people, is much lower than the number of landlines, at almost 70 per hundred. A similar pattern can be seen in Canada. The highest number of landlines in the graph is in Denmark, with about 90 per 100 people. In contrast, the lowest figures for fixed lines are in Italy and the UK.

In conclusion, it seems that mobile phone use is higher in Europe than in North America.

在這個柱形圖中，通過觀察，我們也發(fā)現(xiàn)了幾個趨勢：一是大部分國家手機使用數(shù)量要多于固定電話使用數(shù)量；二是歐洲國家的手機使用量明顯多于北美洲國家。見劃線的句子。我們在觀察圖形的時候，若橫軸是地點，我們還需注意國家的分類，這點在高分范文中尤其可以成為一個亮點。

另外，建議考生們在觀察柱形的時候，還要特別注意落差較大的柱形，有時候以這些柱的數(shù)據(jù)描寫作為突破口也不失為一種很好的嘗試，如上圖中第2段第2個劃線句子，就是以描述意大利的數(shù)據(jù)作為突破口，因為意大利的2根柱的落差是所有國家里最大的。
