The graph is a statistical graph of population growth, read the graph to complete the questions. 小题1:The stage of population growth in which the developing countries in general are now located is A．Ⅰ

Subquestion 1:D

Subquestion 1:D

Test Analysis: The key to this question is to be able to accurately read out the birth rate, death rate and natural growth rate from the graph, and the values of the first two can be The first two values can be read from the vertical and yellow coordinates, but the natural growth rate needs to be read from the right diagonal line, according to the data in the figure it is not difficult to determine, Ⅰ, Ⅱ, Ⅲ, Ⅳ represented by the type of reproduction of the population for the primitive type, modern type, traditional type and transition type.

Subtitle 1:According to the knowledge we have learned, the current population growth in the vast number of developing countries is in the transitional type (Ⅳ). Choice D?

Subtitle 1:The type of population reproduction in most developed countries is the modern-type stage of low births, low deaths and low growth (Ⅱ). The fastest growth of the world's population is in the transitional type (IV) stage due to a large population base, low mortality and high natural growth rate. The transformation of the type of population reproduction is in line with the productivity level at that time, and has roughly passed through four stages from primitive type, traditional type, transitional type and modern type. That is, the whole process of Ⅰ-Ⅲ-Ⅳ-Ⅱ. Therefore, choose D

Comment: This question in the accurate understanding of the textbook on the basis of the transformation of the type of population reproduction, but also need to have a strong ability to read multi-coordinate graphs. The natural growth rate of the population in the test question is not easy to read accurately, the difficulty of the test question is more
