劍橋雅思真題小作文范文篇一：天氣預(yù)報(bào)

話題：The diagram shows the process of weather forecast by Australian Bureau of Meteorology

范文

The figure illustrates the process used by the Australian Bureau of Meteorology to forecast the weather.

There are four stages in the process, beginning with the collection of information about the weather. This information is then analysed, prepared for presentation, and finally broadcast to the public.

Looking at the first and second stages of the process, there are three ways of collecting weather data and three ways of analysing it. Firstly, incoming information can be received by satellite and presented for analysis as a satellite photo. The same data can also be passed to a radar station and presented on a radar screen or synoptic chart. Secondly, incoming information may be collected directly by radar and analysed on a radar screen or synoptic chart. Finally, drifting buoys also receive data which can be shown on a synoptic chart.

At the third stage of the process, the weather broadcast is prepared on computers. Finally, it is delivered to the public on television, on the radio, or as a recorded telephone announcement.

劍橋雅思真題小作文范文篇二：自然界的碳循環(huán)

The diagram below illustrates the carbon cycle in nature.Write a 150-word description of this diagram for a university lecturer.

范文

The diagram shows how carbon moves through various stages to form a complete cycle. This report will give a brief description of the main stages in this cycle.

First, we can see that energy from the sun is transformed into organic carbon through a process in plants known as photosynthesis. This organic carbon is then transferred underground when plants, and the animals that feed on them, die and decay. Some of this carbon is trapped underground in the form of fossils and fossil fuels.

Carbon is also released back into the atmosphere, however, through various means. One is when animals and plants respire, and another is when humans burn fossil fuels in cars and factories. All this carbon enters the atmosphere as CO2. It is then reabsorbed by plants, and the cycle begins again.

Overall, we can see that carbon moves in a natural cycle, although human factors may now be affecting the balance.

劍橋雅思真題小作文范文篇三：價(jià)格變動(dòng)

話題：The graph below shows changes in global food and oil prices between 2000 and 2011.

范文

The line graph compares the average price of a barrel of oil with the food price index over a period of 11 years.

It is clear that average global prices of both oil and food rose considerably between 2000 and 2011. Furthermore, the trends for both commodities were very similar, and so a strong correlation (93.6%) is suggested.

In the year 2000, the average global oil price was close to $25 per barrel, and the food price index stood at just under 90 points. Over the following four years both prices remained relatively stable, before rising steadily between 2004 and 2007. By 2007, the average oil price had more than doubled, to nearly $60 per barrel, and food prices had risen by around 50 points.

A dramatic increase in both commodity prices was seen from 2007 to 2008, with oil prices reaching a peak of approximately $130 per barrel and the food price index rising to 220 points. However, by the beginning of 2009 the price of oil had dropped by roughly $90, and the food price index was down by about 80 points. Finally, in 2011, the average oil price rose once again, to nearly $100 per barrel, while the food price index reached its peak, at almost 240 points.
