“the number of+名词复数+单数谓语”译为“……的数量”；“a number of+名词复数+复数谓语”译为“大量的”，根据is单数可知，用the number of，排除C；一般情况下名词作定语修饰名词时，第一个名词要用单数，但是若man或者women作定语时，man和woman的单复数根据被修饰的名词的单复数而定。根据第二空后的teachers可知，用复数，即women teachers，故选B。

此句考查定语从句的关联词，that/which可以引导定语从句，what，it不能引导定语从句，首先排除C,D；先行词是不定代词one，前面被形容词的最高级best修饰，引导词只能用that不能用which，故答案为A.
【点睛】
引导定语从句的关系代词有：that（指人或物），which（指物），who（指人）。指人时可用that或who，指物时可用that或which，但有时只能用that不能用which。常见的情况有下列五种：
当先行词是all, any, anything, everything, nothing等不定代词时。例如：
Is there anything that I can do for you? 有什么可以为你做的吗?
All that can be done must be done.凡是能做的都必须做。
当先行词被形容词的最高级或序数词修饰时。例如：
That is one of the most interesting books that are sold in the bookshop.那是这家书店出售的最有趣的书之一。
The first thing that we should do is to get some food.我们该做的第一件事是弄点吃的。
当先行词有the only, the very, the same, the last等修饰时。例如：
My necklace is not the only thing that's missing.我的项链不仅是丢掉的东西。
当主句以who或which开头时，定语从句中引导词用that，不用which或who。以避免重
复。例如：
Who is the girl that is wearing a red coat？正穿一件红色外套的女孩子是谁？
）当先行词既有人又有物时，用that不用which。例如：
The writer and his novel that you have just talked about are really well known.你刚才谈起的那位作家以及他的小说确实很著名。

【点睛】
做定语从句时，可先将先行词还原到句中。其次选择关系词，要先看先行词指人、指物还是既指人又指物。二要看从句中做何种成分，从而做出正确的判断。

分类汇编：综合计算题 1.（201潍坊）8如图所示是一种常见的封闭电热水袋，其性能参数如表中所示。已知电热水袋加热 效率为80%，水的比热容c=4.2×103J/（kg?℃），水的密度ρ=1.0×103kg/m3．将袋内20℃的水加热到自动断电，求： （1）袋内水吸收的热量 （2）需要的加热时间 解（1）由ρ=可得袋内水的质量：m=ρ水V=1.0×103kg/m3×1.0×103=1kg， 袋内水吸收的热量： Q=cm（t﹣t0）=4.2×103J/（kg?℃）×1kg×（60℃﹣20℃）=1.68×105J； （2）由η=可得消耗电能：W===2.1×105J， 由P=可得，需要的加热时间：t===525s。 答：（1）袋内水吸收的热量为1.68×105J；（2）需要的加热时间为525s。 2.（2018?青岛）探究小球在斜面上的运动规律如图甲所示，小球以初速度20m/s从A点沿着足够长的光滑斜面滑下，它在斜面上的速度ν随时间t均匀变化。实验数据如下表 （2）小球的运动速度v与时间t的关系式为v= 5m/s2t+2.0m/s ； （3）如图丙所示，以速度v1做匀速直线运动的物体在时间t内通过的路程是s1=v1t1，它可以用图线与时间轴所围矩形（阴影部分）的面积表示。同样，图乙中图线与时间轴所围图形的面积，也能表示这个小球在相应时间t內通过的路程s。上述小球从A点沿光滑斜面滑下，在时间t内通过的路程的表达式为s= 2.0m/s×t+5m/s2t2。
【分析】（1）根据表中数据，由描点法作图； （2）由上图知，小球的运动速度v与时间t的关系式为一次函数关系，设为v=kt+b，将表中前2组数据，代入①得出k和b，得出小球的运动速度v与时间t的关系式； （3）图乙中图线与时间轴所围图形的面积表示这个小球在相应时间t內通过的路程s。根据梯形面积公式写出在时间t内通过的路程的表达式为s。 【解答】解：（1）根据表中数据，在坐标系中找出对应的点，然后连接起，如下图1所示： （2）由上图知，小球的运动速度v与时间t的关系式为一次函数关系，设为v=kt+b﹣﹣﹣﹣①，将表中前2组数据，代入①式有： 2.0m/s=b﹣﹣﹣﹣﹣③ 2.5m/s=k×0.1s+b﹣﹣﹣﹣﹣④ 由③④得：k=5m/s2， 小球的运动速度v与时间t的关系式为： v=5m/s2t+2.0m/s； （3）图乙中图线与时间轴所围图形的面积，也能表示这个小球在相应时间t內通过的路程s，即如上图2梯形ABCD的面积： S梯形ABCD=（BC+AD）×CD×=（2.0m/s+5m/s2t+2.0m/s）×t×=2.0m/s×t+5m/s2t2， s=2.0m/s×t+5m/s2t2。 故答案为：（1）如图1所示； （2）5m/s2t+2.0m/s； （3）2.0m/s×t+5m/s2t2。 3.（临沂）2017年12月24日，我国自主研发的全球最大水陆两栖飞机AG600首飞成功，可为“海上丝绸之路”航行安全提供最快速有效的支援与安全保障。它的最大飞行速度为560km/h，最大航程

A．is B．have C．are 【答案】A 【解析】 【详解】 句意：——我们学校有卖书的活动，你愿意和我一起去看看吗？——当然。我很乐意。本题考查there be结构，表示某地有某物；而have是指某人有某物，空前面是There，因此考查的是there be结构，排除B；再由a book sale是单数名词，因此be 动词用is。故选A。 2．（通常与or连用）或者 Either you or your father must see this young man today. 你或是你的父亲今天必须见这位年轻人。 副词 ad. 3．（两者之中）每一方的;每一的 She studied history and philosophy, but she had little interest in either subject. 她学过历史和哲学,但对这两门课都没有多少兴趣。 代词 pron. 4．______ Lucy ______ you can go to the party.

A．like B．liked C．likes D．liking 【答案】C 【解析】句意：不仅我的同学们而且我的老师都喜欢古诗，因此我们经常分享他们最喜欢的诗。本题考查动词的时态。A. like动词原形； B. liked 过去式；C. likes 单数第三人称； D. liking现在分词形式。Not only···but also···不仅···而且···用于连接两个对等的成分；若连接两个成分作主语，其后谓语动词与靠近的主语保持一致。our English teacher为单数第三人称，故选C 3．There _______ a fashion show _______ the end of this month.

高中化学氮及其化合物计算题分类汇编
(一)氮气 1．氮元素存在形态 空气中含大量N2，是工业生产中N2的主要来源。 2．N2的物理性质 氮气难溶于水，难液化，密度比空气略小（与空气密度相近），只能用排水法收集N2。 3．N2的化学性质 由于氮分子的键能很大，所以氮气的性质很稳定，只有在高温条件下才能发生一些化学变化。 (1)与H2的反应：N2 + 3H22NH3 (2)与O2的反应：N2 + O22NO (3)与Mg的反应：3Mg + N2Mg3N2 4．氮的固定 (1)定义：把大气中游离态的氮转化为氮的化合物的过程称为固氮。 (2)氮的同定的途径 ①生物固氮 豆科植物的根部常附有小根瘤，其中含有固氮菌，能把空气中游离的氮变成氨（铵态氮肥）作为养分吸收，所以这些植物可以少施肥，甚至不施肥。 ②大气同氮 闪电时，大气中的氮转化为氮的氧化物，经降水生成极稀的硝酸（硝态氮肥），渗入土壤被植物根系吸收。 N2 + O22NO 2NO + O2 = 2NO2 3NO2 + H2O = 2HNO3 + NO 【注意】生物固氮和大气固氮统称自然固氮。 ③工业固氮 氮气和氢气在高温、高压并有催化剂存在的条件下，可以直接化合生成氨(NH3)。 N2 + 3H22NH3 工业上就是利用这个原理来合成氨的。 （二）一氧化氮和二氧化氮 1、一氧化氮：无色气体，难溶于水，有很大毒性，在常温下极易被氧化成二氧化氮。2NO＋O2→2NO2 2、二氧化氮：有刺激性气味的红棕色气体，溶于水生成硝酸和一氧化氮。 3NO2＋H2O =2HNO3＋NO 2NO2N2O4（无色） 注意：关于氮的氧化物溶于水的几种情况的计算方法。 ①NO2或NO2与N2（或非O2）的混合气体溶于水时可依据：3NO2＋H2O→2HNO3＋NO 利用气体体积变化差值进行计算。 ②NO2和O2的混合气体溶于水时，由4NO2＋2H2O＋O2 =4HNO3可知，当体积比为 ＝4：1，恰好完全反应 V(NO2)：V(O2) ＞4：1，NO2过量，剩余气体为NO ＜4：1，O2过量，乘余气体为O2 ③NO和O2同时通入水中时，其反应是：2NO＋O2→2NO2，3NO2＋H2O→2HNO3＋NO ，总反应式为：4NO＋2H2O＋3O2→ 4HNO3当体积比为 ＝4：3，恰好完全反应

A．make, worry B．make, be worried C．makes, worried D．makes, worry 【答案】D 【解析】 【详解】 句意：雾霾是一种空气污染。它使人们担心他们的健康。考查主谓一致和动词短语辨析。it是单数第三人称，动词需用三单形式，可排除AB两项。make让，使役动词，make sb. do sth.让某人做某事，是固定结构，可排除C项。根据句意结构，可知选D。 3．It is reported that the population of China smaller in the past few months. The aging（老龄化） is a big problem. More parents are encouraged to give birth to more babies. A．became B．will become C．have become D．has become 【答案】D 【解析】 【详解】 句意：据报道，中国人口在过去的几个月里已经变少了。老龄化是一个大问题。鼓励更多的父母生更多的孩子。A. became变成，一般过去时态；B. will become 将变成，一般将来时；C. have become已经变成，现在完成时；D. has become已经变成，现在完成时，第三人称单数。主语是the population，根据语境可知是现在完成时，其结构has done的形式。根据句意，故选D。 4．（两者之中）每一方的;每一的 She studied history and philosophy, but she had little interest in either subject. 她学过历史和哲学,但对这两门课都没有多少兴趣。 代词 pron.
