河北衡水中学2021届全国高三第一次联合考试 数学 一、选择题：在每小题给出的四个选项中，只有一项是符题目要求的． 1．设集合A ＝{x |x 2-4x +3≤0}，B ＝{x ∈Z |1＜x ＜5}，则A ∩B ＝ A ．{2} B ．{3} C ．{2，3} D ．{1，2，3} 2．若复数z ＝1-i ，则| |1z z =- A ．1 B C ． D ．4 3．某班级要从6名男生、3名女生中选派6人参加社区宣传活动，如果要求至少有2名女生参加，那么不同的选派方案种数为 A ．19 B ．38 C ．55 D ．65 4．数列1，1，2，3，5，8，13，21，34，…称为斐波那契数列，是意大利著名数学家斐波那契于1202年在他撰写的《算盘全书》中提出的，该数列的特点是：从第三项起，每一项都等于它前面两项的和在该数列的前2020项中，偶数的个数为 A ．505 B ．673 C ．674 D ．1010 5．已知非零向量a ，b 满足||||a b =，且|||2|a b a b +=-，则a 与b 的夹角为 A ．2π3 B ．π2 C ．π3 D ．π6 6．为加快新冠肺炎检测效率，某检测机构采取合并检测法，即将多人的拭子样本合并检测，若为阴性，则可以确定所有样本都是阴性的，若为阳性，则还需要对本组的每个人再做检测．现对20名密切接触者的拭子样本进行合并检测，每份样本的检测结果是阴性还是阳性都是相互独立的，每人检测结果呈阳性的概率为p ，且检测次数的数学期望为20，则p 的值为 A ．12011()20- B ．12111()20- C ．12011()21- D ．121 11()21 - 7．已知未成年男性的体重G （单位：kg ）与身高x （单位：cm ）的关系可用指数模型G ＝a e bx 来描述，根据大数据统计计算得到a ＝2.004，b ＝0.0197．现有一名未成年男性身高为110 cm ，体重为17.5 kg ，预测当他体重为35 kg 时，身高约为(ln 2≈0.69) A ．155 cm B ．150 cm C ．145 cm D ．135 cm 8．已知正方体ABCD -A 1B 1C 1D 1的棱长为2，M 为CC 1的中点，点N 在侧面ADD 1A 1内，若BM ⊥A 1N ．则△ABN 面积的最小值为 A B C ．1 D ．5 二、选择题：在每小题给出的选项中，有多项符合题目要求． 9．已知π3cos()55α+=，则3 sin(2π)5 α-= A ．2425- B ．1225- C ．1225 D ．24 25 10．已知抛物线C ：y 2＝4x ，焦点为F ，过焦点的直线l 抛物线C 相交于A (x 1，y 1)，B (x 2，y 2)两点，则下列说法一定正确的是 A ．|A B |的最小值为2 B ．线段AB 为直径的圆与直线x ＝-1相切 C ．x 1x 2为定值 D ．若M (-1，0)，则∠AMF ＝∠BMF
