UKiset文字推理题解题技巧

　　有不少家长认为，儿童教育要从小抓起。鉴于英国教育水平处于世界领先地位，一些家长选择把孩子送到英国去读中小学。说到这，就必须要提一下UKiset考试了。UKiset考试是很多英国私立学校招生的一个辅助测试，其中的文字推理题也是非常重要的，今天小编就给大家讲解一下UKiset文字推理题解题技巧！

　　Typically, when people contract an infectious disease, their immune system immediately begins to produce extra white blood cells to fight the disease. The scatterplot shows the white blood cells reproducing in an infected patient, along with several values found when modeling the data using a graphing calculator. According to this model, how many white blood cells per microliter of blood did the patient have before he contracted the disease?

　　(A) 3,400

　　(B) 8,500

　　(C) 10,000

　　(D) 13,600

　　分析：问题是：contract the disease 前对应的white blood cells per microliter of blood数量，所以应该求t = 0 时Blood cell数量。图表反应的是：感染病人体内white blood cells同hour的变化关系，呈现上升趋势，并且纵坐标单位为thousands per mcl。结合上升趋势以及table中给出数据判断出为exponential growth model，每过一个小时白细胞数量变成原来两倍。此题特殊之处在于原点并非t = 0 时对应的初始值，所以还要往前推。t = 4, y = 136，所以t = 3, y = 68依次推得：t = 0 , y = 8.5 结合纵轴单位度量，答案为8500。

　　所以此题结合问题以及图示就可以得出答案，不需要重读前面的背景部分。

　　An occupational health organization published a study showing an increase in the number of injuries that resulted from elderly people falling in the bathtub. In response to this increase, a medical supply company decided to drop its price on bathtub lifts from $450 to $375, hoping to still break even on the lifts. The company breaks even when its total revenue (income from selling n bathtub lifts) is equal to its total cost of producing the lifts. If the cost C, in dollars, of producing the lifts is C = 225 n + 3,150, how many more of the lifts does the company need to sell at the new price to break even than at the old price?

　　(A) 7 (B) 12 (C) 14 (D) 21

　　UKiset考试官网分析：观察问题： how many more of the lifts does the company need to sell at the new price to break even than at the old price?所以是一题减法题。涉及到一个经济学词汇“break even”，向前扫读有解释：total revenue (income from selling n bathtub lifts) is equal to its total cost of producing the lifts 所以意思是收入 = 成本，所以问题问的是新价格下盈亏相抵要比旧价格下盈亏相抵多卖多少电梯。 成本公式为 C = 225 n + 3,150

　　扫读背景中的数字为价格从450下降为375，可设原价为a, 新价为b，列式：

　　450a = 225 a + 3,150 375b = 225 b + 3,150 解得： a = 14, b= 21

　　最终答案为a – b = 7 选 A

　　所以同学们有了解到文字题的读题顺序以及注意事项吗?最主要的是克服恐惧心理，多练习读题方法，而不是一遍遍读题。

　　看完之后，如果有不会的同学们可以拿出笔记本出来详细的记录一下，虽然小编整理的还是不够全面，不过当你们如果碰到不会的东西的时候，拿笔写一写，画一画，比你直接看一眼就过去要好多了，都说好记性不如烂笔头，所以一定要时时刻刻保持做笔记的好习惯。如果想了解更多UKiset考试题型可以持续关注本网站！
