2020年军队文职考试考试：巧记同比与环比
同比和环比是资料分析中常见的两种增长方式，很多同学对于这两种增长方式了解和掌握并不好，以至于如果题目中同时出现同比和环比时候容易混淆，找不到正确的数据，导致题目做错，接下来，红师教育就带大家来仔细甄别一下这两种增长方式。 一、概念 同比：与最大的时间概念向过去循环一个周期做比较。 环比：与最小的时间概念向过去循环一个周期做比较。 举例：2017年12月 在这个时间概念里，出现了两个时间概念，分别为年和月，根据常识，我们知道较大的时间概念为年，较小的时间概念为月，所以，同比就是把较大的时间概念2017年向前循环一个周期即为2016年，即2017年12月的同比为2016年12月;对于环比来讲，较小时间概念12月，向前循环一个周期为11月，所以2017年12月的环比为2017年11月。
接下来，通过一个表格让考生对同比和环比。 二、同比和环比的表述形式 同比：2012年税收收入100601亿元，同比增长. 2012年税收收入100601亿元，增长了. 2012年税收收入比2011年增长了. 2012年税收收入100601亿元，比上年同期增长了. 环比：2013年3月税收收入80203亿元，环比增长了. 2013年3月税收收入为80283亿元，比上月增长了. 例.2016年12月，全规模以上工业实现产值亿元，同比增长，比上月增长了。 (1)2015年12月全规模以上工业实现产值多少亿元? (2)2016年11月全过规模以上工业实现产值多少亿元?

发布时间：2017-06-29 22:29:01Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed himuntil 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail(桶) with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make.1. Hundreds of years ago, Sir Francis Bacon found _______.A. the temperature of warm water drops faster than that of cold waterB. warm water is heavier than cold waterC. warm water has the same temperature as cold waterD. warm water is not as useful as cold water2. What Sir Francis Bacon said was right, but people didn"t believe him until _______.A. late in the 20th century B. early in the 20th centuryC. three years ago D. late in the 19th century3. Leave a pail with warm water and another pail with cold water in the same low temperature, you ll find that _______.A. cold water freezes firstB. warm water turns into ice before cold waterC. warm water and cold water freeze at the same timeD. much of cold water is changed into air.4. Why does warm water freeze first in the same freezing weather?A. Because some of the warm water turns to vapor, the amount(数量) becomes less than that of cold water.B. Because warm water is lighter than cold water.C. Because the temperature of warm water is lower than that of cold water.D. Because cold water freezes with more difficulty than warm water.1.A。细节题。据第1句和第2句可知答案为A。2.A。细节题。根据 But few people believe him until 1970可知答案为A。4.A。推断题。根据 Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen可知答案为 A。
