雅思作文部分中的第一个作文常常被称为小作文，这类作文多是图表作文题目。那么对于这类作文中常常出现的数字比较如何表达更容易得到高分呢？
1. 两者的比较
寻求一个切入点（比较大的值），随后与另一个值进行比较。通过数值强调比较的差值。比较有三种表示方法：
第一种：直接展示法
e.g. 王浩6:7马琳（The score of Mr. Wang is 6, compared with 7, that of Mr. Ma. ）
第二种：减法subtraction (more, less, fewer)
The score of Mr. Ma is 7, 1 more than that of Mr. Wang. 7 = 1+(6)
第三种：寻找倍数times
e.g. Mr. Chow’s IQ 80: 160 Mr. foot‘s IQ
Mr. Foot’s IQ reaches 160, 2 times (double) Mr. Chow’s IQ.
Mr. Wang Yi’s popularity 20%: 10% Mr. Tao’s popularity
Water consumption in Brazil and Congo in 2000
|
Country |
Population |
Irrigated land |
Water consumption per person |
|
Brazil |
176 million |
26,500 km² |
359 m³ |
|
Democratic Republic of Congo |
5.2 million |
100 km² |
8 m³ |
In 2000, the water consumption per person of Brazil with 176 million people reached 359 m3, compared with 8 m3, that of Democratic Republic of Congo at the population of 5.2 million. The area of irrigated land in the former was found 26,500 km2, 265 times that of the latter.
NB：
在描述的过程中，始终要记得名词需要配合量词使用（因为服务对象是数字）。此外，因为比较同样的对象，因此比较的前后在词性必须保持一致。如：The percentage of Brazil is more than Congo.这样的句子就是一种错误。
2. 三者或三者以上的比较
You should spend about 20 minutes on this task.
The table below shows the proportion of different categories of families living in poverty in Australia in 1999.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
|
Family type |
Proportion of people from each household type living in poverty |
|
single aged person aged couple single, no children couple, no children sole parent couple with children all households |
6%(54，000) 4%(48，000) 19%(359，000) 7%(211，000) 21%(232，000) 12%(933，000) 11%(1，837，000) |
题目特点：比较数值众多（3者以上，应用最高级），基线明显（黑体字，起作用是其他的数值的比较对象，并帮助我们进行数字分类）。
所有的数值代表的是在某一种特定的家庭中贫困人数的比例(The percentage of people from … in poverty.)
来自所有家庭中贫困的比例达到11%，其对应equivalent to大概1.8 million。在单身和单亲家庭中贫困人数的比例，最高的两个，相当于上面平均值the above average的2倍，但是在两者中有孩子的家庭贫困比率达到21%，比没有孩子的家庭高了2%。相似的，那些有孩子的双亲家庭的比例是12%，略高于平均值，要比没有孩子的双亲家庭的比例高出了5%，明显低于平均值。在所有的家庭种类中，那些有老年人的家庭贫困的比例最低分别是6%和4%，并且有两个老年人的贫困家庭比例更低些。
The percentage of people from all household in poverty reaches 11%, equivalent to nearly 1.8 million. That of poor single family without children and sole-parent family, the top two, is about double 11%, but that of the latter, 21%, higher 2% than that of the former. Similarly, the percentage of people from couple-with-children family in poverty is 12%, slightly higher than the average, more 5% than that of couple-without-children family, lower than the average. Of all family types, those with aged people have the lowest percentage in poverty, 4% and 6%, and the proportion with aged couple is lower.
