2018届高三英语最后一课(20200223164012)

同学们,大家好! 这份考前辅导材料先从一则故事入手,让我们先来走进它: 1968年,在墨西哥奥运会的百米赛道上,美国选手吉?海因斯撞线后,转过身子看运动场上 的记分牌。当指示灯打出9.95秒的字样后,海因斯摊开双手自言自语地说了一句话。这一 情景通过电视网络,全世界至少有好几亿人看到,可是由于当时他身边没有话筒,因此海因 斯到底说了句什么话,谁都不知道。但人们清楚地知道这是人类历史上首次有人在百米赛道 上突破10秒大关。 1984年,洛杉矶奥运会前夕,一位叫戴维?帕尔的记者在办公室回放墨西哥奥运会的资 料片,当再次看到海因斯回头、摊手、自言自语的镜头时,他想他一定说了一句不同凡响的 话。但这一新闻点,竟被当时400多名在现场的记者给漏掉了,这实在是个天大的遗憾。于 是他决定去采访海因斯,问他当时到底咕哝了句什么话。当被问起16年前的事时,海因斯想了想笑着说:“当时难道没人听见吗?我说,上帝啊,那扇门原来是虚掩着的!” 谜底揭开之后,戴维?帕尔接着对海因斯进行了采访。针对那句话,海因斯说:“自美国运动员欧文斯于1936年5月25日在柏林奥运会上创下10.03秒的百米赛世界纪录之后,以詹姆斯?格拉森医生为代表团的医学界断言,人类的肌肉纤维所承载的运动极限不会超过 每秒10米,的确,这一纪录保持了32年,这一说法在田径场上非常流行,我也以为这是真的,但是,我想我的最高水平该跑出10.01秒的成绩。于是,每天我以自己最快的速度跑50公里。因为我知道,百米冠军不是在百米赛道上练出来的。当我在墨西哥奥运会上看到自己 9.95秒的纪录之后,我惊呆了,原来10秒这个门不是紧锁着的,它虚掩着,就像终点那根 横着的绳子。” “百米冠军不是在百米赛道上练出来的。”,“每天我以自己最快的速度跑50公里。”同学们,就是这每天的坚持成就了海因斯在最后的赛道上突破了自己的“10秒大关”,推开了虚掩着的成功之门,成就了自己,创造了历史。 高考不也如此?看似枯燥、单调、甚至令人心烦的一份一份小练、一题一题讲解、一遍 一遍重复,回想起来不正是铺就了我们通向虚掩着的那扇门吗? 越是接近终点,越要屏气凝神、步履坚定、成竹在胸。因为我们知道,翻过了这份“考 前辅导材料”,“2018年高考卷”的尊容就在那扇虚掩着的门背后。 去吧,去轻轻地推开它! 高三英语组全体老师预祝莘莘学子梦想成真! 2018届高考英语考前辅导 应试总方法:“一看二序三速四查”。 一看:充分利用考前5分钟,认真阅卷,同时调节紧张的心理。阅卷时要注意,答题要求、 题量、总页码及正反面的试题。不要迫不急待答题。“磨刀不误砍柴工”。 二序:遵循先易后难的原则,不要违反规律。 三速:在规定的120分钟内完成全部试题需要一定的速度。以下为各项题目建议时间分配:(学生可根据自己的实际作适当调整) 听力单项、完形阅读理解任务型书面表达涂卡、整理 20分钟25分钟35分钟13分钟25分钟2分钟(建议做好一大题 就涂好一大题) 四查:在完成全部试题后要认真检查: 1. 试题是否全部完成(包括正、反面)。不要轻易改答案(尤其是阅读理解),除非恍然大悟。 2. 答题卡是否全部涂规范、正确,考号、姓名、科目等是否正确无误。 3. 对漏做、疑难的题目进行强攻。

It includes airfare ($225), hotel ($170), dining out ($116) and dressing up ($95) and the gift. If you have weddings to attend this year, here are some tips for you to avoid breaking the bank. 1. Book flights in advance The moment you decide to attend a wedding is the time to check flight prices at the best time. Plane fares are higher in the summer, especially in July and August. Booking in advance will save you money, as will watch for sales on lower-cost carriers like JetBlue and Frontier. You can check Google Flights for a calendar of prices showing the cheapest days to fly from apps like Hopper to get real-time alerts when a fare is at its lowest price point. 2. Don't blow your budget on the gift If you've got the money, an expensive gift is lovely. But there's no need to take out loans to prove your love for the happy couple. Skip an expensive necklace by giving (an appropriate amount of) cash instead. To save on the gift, consider making one: A photo album or scrapbook of memories with the bride and groom shows how much you care. You could also share the gift with other guest(s) or even make gifts with DIY ideas by yourself to save money. 3. Use old dresses and suits You don't always have to be on a new dress for a wedding. While men have the option of repeating their suits, women are more likely to spend money on new clothes for the special occasion. But before you take out your wallet, consider reinventing something already in your

2018届河南省中原名校(豫南九校)高三上学期第四次质量考评试题 物理

河南省中原名校(豫南九校)2018届高三上学期 第四次质量考评(期中)物理试题 一、选择题:本题共10小题,每小题5分,共50分。在每小题给出的四个选项中,第1—6题只有一个选项正确。第7—10题有多个选项正确,全部选对的得5分,选对但不全的得3分,有选错的得0分。 1. 如图所示为氢原子的能级分布图,已知可见光光子的能量在1.61eV~3.10eV范围内,由图可知 A. 基态氢原子吸收能量为10.3eV的光子能从n=1能级跃迁到n=2能级 B. 基态氢原子的电离能为13.6eV C. 一群处于n=5能级的氢原子向低能级跃迁时,可辐射6种不同频率的光子 D. 氢原子从n=4能级跃迁到n=3能级,辐射的光子是可见光 【答案】B 【解析】A、根据玻尔理论可知,氢原子能级跃迁时,吸收的光子能量必须严格等于能级差,A项错误;B、基态氢原子电离时的电离能为13.6eV,B项正确; C、一群处于n=5能级的氢原子向低能级跃迁时,可辐射种不同频率的光子,C项错误; D、氢原子从n=4能级跃迁到n=3能级,辐射的光子的能量为-0.85eV-(-1.51eV)=0.66eV,能量比可见光光子的能量小,不可能是可见光光子,D项错误。故选B。 【点睛】只有入射光子的能量大于金属的逸出功才会发生光电效应.能级间跃迁辐射或吸收的光子能量等于两能级间的能级差,根据辐射的光子能量与可见光的光子能量比较进行判断. 2. 如图所示为甲、乙两质点做直线运动的v-t图象,若两质点从同一地点出发,到时刻相遇,则下列说法正确的是()

A. B. C. D. 时间内,甲、乙相距的最大距离为3m 【答案】C 【解析】C、由图可知,甲的加速度,乙的加速度,则,求得,C项正确;A、,A项错误;B、 ,B项错误;D、内,甲、乙相距的最大距离为 ,D项错误。故选C。 【点睛】本题是速度-时间图象问题,要明确斜率的含义,知道在速度--时间图象中图象与坐标轴围成的面积的含义,即可分析两物体的运动情况. 3. 将一右端带有固定挡板的长薄板放在水平面上,一质量不计的弹簧右端拴接在挡板上,左端拴接一可视为质点的滑块,当弹簧原长时滑块位于长薄板的O点,将滑块拉至图中的A点,整个装置处于静止状态。现将长薄板的右端缓缓地抬起直到滑块将要沿长薄板下滑。滑块所受的摩擦力以及支持力的大小分别用表示。则在上述过程中下列叙述正确的是() A. 先减小后增大、一直减小 B. 先增大后减小、一直增大 C. 一直增大、先减小后增大

【数学】河南省豫南九校联考2018-2019学年高一上学期期末考试试题(解析版)

河南省豫南九校联考2018-2019学年 高一上学期期末考试数学试题 一、选择题 1.同学们,当你任意摆放手中笔的时候,那么桌面所在的平面一定存在直线与笔所在的直线 A. 平行 B. 相交 C. 异面 D. 垂直 【答案】D 【解析】由题意,若笔所在直线若与地面垂直,则在地面总有这样的直线,使得它与笔所在直线垂直;若笔所在直线若与地面不垂直,则其必在地面上有一条投影线,在平面中一定存在与此投影线垂直的直线,由三垂线定理知,与投影垂直的直线一定与此斜线垂直, 综上,当你任意摆放手中笔的时候,那么桌面所在的平面一定存在直线与笔所在的直线垂直.故选:D. 2.已知直线l经过点,且斜率为,则直线l的方程为 A. B. C. D. 【答案】A 【解析】直线经过点,且斜率为,则, 即,故选A. 3.若线段AB的长等于它在平面内的射影长的2倍,则AB所在直线与平面所成的角为() A. B. C. D. 【答案】C 【解析】如图,AC⊥α,AB∩α=B, 则BC是AB在平面α内的射影,

则BC=AB,所以∠ABC=60°,它是AB与平面α所成的角.故选C. 4.下列函数中,满足的单调递增函数是 A. B. C.
