The chart below shows the total number of minutes (in billions) of telephone calls in the UK, divided into three categories, from 1995-2002.下面的图表显示了英国的电话通话总次数(数十亿)，从1995年到2002年，分为三类。
Introduction: rewrite the question statement in your own words.
Overview: point out which category was highest in each year, which was lowest, and which saw the biggest changes.
Details: compare the 3 categories in 1995, then say what happened up until 1999.
Details: notice what happened to local calls from 1999 onwards, and contrast this with the other 2 categories. Finish with a comparison of the figures in 2002.
The bar chart compares the amount of time spent by people in the UK on three different types of phone call between 1995 and 2002.
It is clear that calls made via local, fixed lines were the most popular type, in terms of overall usage, throughout the period shown. The lowest figures on the chart are for mobile calls, but this category also saw the most dramatic increase in user minutes.
In 1995, people in the UK used fixed lines for a total of just over 70 billion minutes for local calls, and about half of that amount of time for national or international calls. By contrast, mobile phones were only used for around 4 billion minutes. Over the following four years, the figures for all three types of phone call increased steadily.
By 1999, the amount of time spent on local calls using landlines had reached a peak at 90 billion minutes. Subsequently, the figure for this category fell, but the rise in the other two types of phone call continued. In 2002, the number of minutes of national / international landline calls passed 60 billion, while the figure for mobiles rose to around 45 billion minutes.
