advise sb.to do sth.表示建议某人做某事，对方是否采纳则不一定。①Jack finally persuaded his father to give up smoking.杰克终于说服他父亲戒了烟。

interest作“利益”讲时，多用复数形式，既可指集团、群体的利益，又可指个人的利益。interest作不可数名词时，意为“利息”；

profit着重收益，尤指从物质、钱财等方面获得的利益；

反馈10.5 In China，nobody is to ______ with killing someone.A．get across B．get through C．get away D．get over

考点归纳拓展 【思路点拨】

1.1 D 根据was pleased to see it worked better可知这个男孩被劝服听朋友的话，故答案为D项。

1.2 A 句意：我试图说服她戒掉抽烟的习惯，但是她不听。try to persuade sb.to do sth.表示试图说服某人做某事，含有未能成功的意思，符合语境。

1.3 C 句意：我建议他不要抽烟，但是他没有听从我的建议。A项表示说服了他不抽烟，与后半句矛盾；advise sb.to do sth.建议某人做某事，符合语境，故C项正确。

1.4 B suggest sb.doing是唯一正确的搭配，意为“建议某人做某事”。

2.1 D 句意：如果你认为对女人好就意味着凡事都向她请示，那你恐怕就错了。mean to do sth.意为“打算做某事”；mean doing sth.意为“意味着做某事”，故选D项。

2.2 A 句意：她本意是想帮他，却反而让情况变糟了。mean to do意为“意欲做某事”。2.3 ①have ②has means意为“方式；方法”，单复数同形。当means由every修饰时，显然是单数，谓语用单数形式。如果means由all修饰则为复数，谓语用复数形式。

2.4 D 句意：旨在让那些低端就业的大学生获益，这个高科技项目有望创造1万个左右计算机编程和测试领域的就业岗位。the project和mean是被动关系，故应为meant；be meant to do是固定用法，为目的含义，故答案为D项。

2.5 B 句意：对于他来说，从艺是一种谋生手段。根据句意，stage 表示从艺，是一个抽象概念，其前不可以加不定冠词；means为单复数同形的名词，此处表示“一种方式”，用 a means of 表达。

3.1 A 句意：新的《劳动法》将使更多的人受益，特别是工人将从中受益。benefit sb.“使某人受益”；benefit from“从„„中受益”，故A项正确。

3.2 D 句意：跟上亚洲形势的发展会有帮助。beneficial “有益的”，符合题意。fortunate “幸运的”；dangerous “危险的”；safe“安全的”。

3.3 ①benefit ②advantage

3.4（1）for the benefit of（2）is beneficial to 4.1 C 句意：他很有关系，所以到毕业时肯定有人推荐他做一份好工作。recommend sb.for sth.为固定用法，意为“推荐某人某事物”，符合题意。

4.2 B 全句意思是：旅馆管理部门恳请客人晚上11点后不要打开收音机。句中的谓语动词request（请求）所引导的从句应当用虚拟语气，即动词原形或“should＋动词原形”。本句的主语从句中，谓语应当用被动语态。所以，答案应为not be played。在上述这类句子中不能用动词过去时形式表示虚拟语气，所以A项不正确。not to play是动词带to的不定式，不能在句中作谓语。did not play也是动词play的过去时形式，同样不能在本句中作为

法还是值得考虑的。B make up“组成；化妆；编造”；figure out“理解；弄清楚”；look through“浏览”；put off“推迟”。句意：目前的形势非常复杂，因此我认为要花费我一些时间来弄清楚它的真实性。

10.1 A 此题考查以get为中心词的短语用法。get down to表示“开始认真对待”“开始认真考虑”。由题意可知应为“我们该认真对待我们的学习了”，故答案为A项。

10.2 A 句意：那座火山剧烈的喷发而山脚下的那个村庄竟然安然渡过危险。此处用come through表示“（安然渡过）危机，疾病等”。

10.3 A 考查动词短语的用法。get along“（勉强）生活；进展”；come on “开始”或用于祈使句表鼓励、催促等；watch out“当心，注意”；set off “动身；出发”。根据句意可知A项正确。

10.4 B A项意为“偶遇”；B项意为“克服（困难等）”；C项意为“来访”；D项意为“下车”。句意：如果我们能克服目前的困难，那么一切都会好起来的。

10.5 C 句意：在中国，没有人在杀了人的情况下能逃脱惩罚。get away with（doing）sth.意为“在犯了某罪的情况下逃脱惩罚”。

I used to hate being called upon in class mainly because I didn’t like attention drawn to myself.And36otherwise assigned（指定）a seat by the teacher, I always37to sit at the back of the classroom.All this38after I joined a sports team.It began when a teacher suggested I try out for the basketball team.At first I thought it was a crazy39because I didn’t have a good sense of balance, nor did I have the40to keep pace with the others on the team and they would tease me.But for the teacher who kept insisting on my “41forit”, I wouldn’t have decided to give a try.Getting up the courage to go to the tryouts was only the42of it!When I first started43the practice sessions, I didn’t even know the rules of the game, much44what I was doing.Sometimes I’d get45and take a shot at the wrong direction—which made me feel really stupid.46, I wasn’t the only one “new” at the game, so I decided to47on learning the game, do my best at each practice session, and not be too hard on myself for the things I didn’t48

第四篇：高考英语完形填空复习教案

高考英语完形填空复习教学设计

教学设计

学习内容：高三完形填空复习学习目标：

一、语言技能目标： 能进一步强化基于信息词完形填空的能力 二、语言知识目标：能进一步强化信息词的了解。

三、学习策略、文化意识、情感态度价值观目标：能进一步强化基于信息词进行完形填空的策略。教学过程： step1：revison revise the skills when doing cloze： 解题思路：

一.跳读全文，辨体裁，抓大意。

1.把握开头，注意主题句，把握5w和1h，抓故事情节。力求首段把握文章主题。

2.根据每段信息词，概括每段大意。

3.注意尾段信息词所强调的中心，往往形成前后呼应。二.试填，找暗示，先易后难。

三.复核，通读全文，检查思路是否顺畅，有无逻辑错误，同时填补遗漏的难题。高考常考命题点： 1.复现：同词、同义、结构复现

2.关联关系：因果、并列（同类）、类属、相对（转折）关系 3.常识运用（背景知识、生活常识）4.固定搭配

step2：finding the informative words and understanding the main idea.1.style：narrative（记叙文）

2.ask a student to report the main idea of the passage.3.class work： discuss the main factors of this passage.who： an old man and i what： he was doing a language research by asking a saleswoman for a way many times.when： before my first year of university where： in a department store the result： the man became my university professor.group work： discuss the mistakes the students made.and：（1）which answer is correct？

1、关联关系；

2、词义辨析；，step4： homework let’s do more exercise to consolidate.reflection and summary：

1、高考完型填空题型专题复习备考时，学生要随时跳出应试者的角色，改变角色，变应试者为故事剧中人的角色，联系语境，设身处地换位思考理解剧中人的思想情感去选出答案，或进一步变为出题人的角色，站在更高的角度，熟悉高考常考命题点，去把握本题型答题技巧，备考策略，可能会有意想不到的收获。

2、完形填空的短文通常没有标题且文章的首句和尾句，一般不设空，要特别注重对首、尾句的理解，因为它们往往提示或点明文章的主题，对理解全文有较大帮助。

3、第一遍通读带有空缺单词的短文时可能一时把握不住短文内容，弄 不清头绪，这是很正常的。此时要注意克服畏难情绪和急躁心理，应稳定情绪，再将短文读一、二遍，直到明确大意为止。

4、做题时切勿一看到一个空格就急着选出一个答案，这样往往只见树木不见树林。由于缺乏全局观念，极易导致连续选错。因为完形填空不同于单个句子的选词填空，其空白处是位于一篇文章之中，因此必须纵观全文、通篇考虑。

总之，做完形填空题，了其大意，先易后难，瞻前顾后，通过直接暗示、间接暗示，前、后暗示，层次、段落暗示，逻辑、推断暗示做题是非常关键的。当然，更重要的是扩大阅读面，增加阅读量，积累语言经验，培养语感能力。望大家反复认真阅读，对提高解答完形填空的能力大有裨益。

本专题由数列和数学归纳法两部分主要内容组成，它融代数、三角、几何于一体，性质多、技巧性强、方法灵活、应用广泛、综合能力要求高．等差、等比数列的运算和性质是本专题复习的重点，以等差、等比数列为载体的代数推理问题，数列的实际应用问题及数学归纳法的应用是难点，它们都是高考命题的热点；方程观点、等价转换、消元法、待定系数法是贯穿于本专题的重要数学思想和方法；运算能力、逻辑思维能力、分析问题和解决问题的能力是复习好本专题的基本要求．

 1．关于等差、等比数列

（1）等差、等比数列的判定：①利用定义判定；②ａｎ＋ａｎ＋２＝2ａｎ＋１

ａｎａｎ＋２＝ａｎ＋1（ａｎ≠0）

２２｛ａｎ｝是等差数列，｛ａｎ｝｛ａｎ｝是等差数｛ａｎ｝是等比数列；③ａｎ＝ａｎ＋ｂ（ａ，ｂ为常数）是等差数列，Ｓｎ＝ａｎ＋ｂｎ（ａ，ｂ为常数，Ｓｎ是数列｛ａｎ｝的前ｎ项和）

列．

（2）等差、等比数列性质的应用：注意脚码、奇偶项的特点等．

（3）数列是定义域为自然数集（或自然数集的子集）的函数，即ａｎ＝ｆ（ｎ）（ｎ∈Ｎ）．因此我们可运用函数的思想方法去研究处理数列问题．如等差数列当公差ｄ≠0时的通项公式为ｎ的一次函数，前ｎ项和为ｎ的二次函数，有关前ｎ项和的最大、最小问题可运用二次函数的性质来解决．

2．关于一般数列

（1）已知数列的前n项和，求通项公式，这类问题常利用

Ｓ１（ｎ＝1），ａｎ＝ Ｓｎ－Ｓｎ－１（ｎ≥2）求解．

（2）用递推公式给出来的数列，常利用“归纳—猜想—证明”的方法求解．

3．关于数列的求和

（1）公式法：①等差、等比数列的前n项和公式；②自然数的方幂和公式．

（2）错位相减法．

（3）倒序相加法．

（4）裂（拆）项法．

4．关于数学归纳法

（1）数学归纳法的原理．

（2）数学归纳法的应用：①证明与自然数有关的恒等式；②用数学归纳法证明不等式；③用数学归纳法证明整除性问题．

（3）归纳—猜想—证明．
