您是一位中国顶级的初中数学讲师,图片中的提请帮忙详细讲解下---```text Question Stem: 2. 实数a,b在数轴上的位置如图所示, 以下说法正确的是 ( ) Options: A. a+b=0 B. b0 D. |b|<|a| Chart Description: Type: Number line Main Elements: - A horizontal line with an arrow pointing to the right, representing the positive direction. - The number line is marked with integers: -2, -1, 0, 1, 2. The spacing between consecutive integers is uniform. - A point labeled 'a' is marked on the number line between -2 and -1. - A point labeled 'b' is marked on the number line between 0 and 1. - Point 'a' appears to be approximately at position -1.6. - Point 'b' appears to be approximately at position 0.6. - Point 'a' is to the left of 0, indicating a is negative. - Point 'b' is to the right of 0, indicating b is positive. - Point 'a' is to the left of point 'b', indicating a < b. - The distance of 'a' from 0 (|a|) is greater than 1 (since a is to the left of -1). Specifically, 1 < |a| < 2. - The distance of 'b' from 0 (|b|) is less than 1 (since b is between 0 and 1). Specifically, 0 < |b| < 1. ```
