B2. D 【解析】逐项分析如下：3. C 【解析】⎩⎪⎨⎪⎧2x －4<0①x ＋3≥0②，解不等式①，得x <2，解不等式②，得x ≥－3，∴不等式组的解集为－3≤x ＜2，表示在数轴上如选项C .4. C 【解析】逐项分析如下：5. A 【解析】依题意，得(x ＋x ＋2)2＝4×35＋22，即x 2＋2x －35＝0.6. D 【解析】联立⎩⎪⎨⎪⎧y ＝－x ＋1y ＝－2x ，解得⎩⎪⎨⎪⎧x ＝－1y ＝2或⎩⎪⎨⎪⎧x ＝2y ＝－1.∴A (－1，2)，B (2，－1)，y 1<y 2即一次函数的图象在反比例函数图象的下方，结合题图可知，当y 1<y 2时，x 的取值范围是－1＜x ＜0或x ＞2.7.
