这是2017年全国二卷的航天部分的选择题，是对开普勒三定律的考查；
答案：CD
解析：由于海王星从P运动到Q点的时间为T0/2,而海王星在近日点时，速度大，所以从P到M的用时小于T0/4，所以A错；从Q到N的阶段，只有万有引力做正功，重力势能和动能相互转化，机械能守恒，故B错；从P到Q是从近日点到远日点，所以速度逐渐减小，故C对；从M到N的过程中由M到Q万有引力做负功，从Q到N万有引力做正功，故D对

1—5题答案：ABBCD
6—10题答案：CBBDA，DA（其中11-12题连续给出DA）
具体题目解析示例：
第4题：记$S_n$为等差数列的前$n$项和，若$S_6=36$，$S_9=81$，通过等差数列性质可求得公差为B.2。
第10题：已知抛物线$C:y^2=4x$的焦点$F$，过$F$作两条互相垂直的直线$l_1,l_2$，与抛物线交于$A,B$和$D,E$两点，求$|AB|+|DE|$的最小值。通过抛物线性质和直线方程联立求解，可得最小值为A.16。

高考英语语法填空答题技巧
一、已给单词提示题型的技巧
此类题可以考查学生对单词形式变化的掌握程度。
本质教育高考数学破题解析核心为“数学三招”：翻译、特殊化、盯住目标，以下结合2017全国Ⅰ卷第10、11题展示具体应用：
2017全国Ⅰ卷第10题解析题目：已知F为抛物线$C:y^2=4x$的焦点，过F作两条互相垂直的直线$l_1, l_2$，$l_1$与C交于A、B两点，$l_2$与C交于D、E两点，求$|AB|+|DE|$的最小值。
翻译：将文字转化为几何图形。抛物线$y^2=4x$的焦点为F(1,0)，过F的两条互相垂直的直线$l_1$和$l_2$分别与抛物线交于A、B和D、E。
盯住目标：目标为求$|AB|+|DE|$的最小值。根据图形，$|AB|$和$|DE|$均为抛物线的焦点弦，其长度公式为$frac{2p}{sin^2theta}$（$p$为抛物线参数，$theta$为弦的倾斜角）。
对于$l_1$，设其倾斜角为$theta$，则$|AB|=frac{4}{sin^2theta}$。
由于$l_1 perp l_2$，$l_2$的倾斜角为$theta + frac{pi}{2}$，因此$|DE|=frac{4}{cos^2theta}$。
哈佛专家组评点2017年江苏省高考试题（二）英语知识运用部分
一、总体评价
高考作为选拔性考试，其试题的严谨性和准确性至关重要。然而，经过哈佛专家组的仔细审查，发现2017年江苏省高考英语试题存在多处问题，这些问题不仅影响了试题的公平性，也可能对学生的英语学习产生误导。
二、具体分析
第26题
原题：We choose this hotel because the price for a night here is down to $20, half of _________ it used to charge.
答案：C（what）
问题：原句中的“Price for a night here”表达不地道，应改为“its cost per night”或“the cost for a night stay”。此外，“half of what it used to charge”虽然语法上无误，但实际应用中更常用“half of its old price”或“halved”。
