a young boy,his greatest passion was in football.He played it whenever he had the chance.Sometimes he would go and watch a game with his friends.When David Beckham was 12 years old,he won the Bobby Charlton Soccer Skills award.This was an important step forward for this young boy,and it led him to go for a visit to a football training camp in Spain.As a boy he played for schools of Essex and also for his county team.In 1991,he became a trainee with Manchester United.This meant that he could practice football as much as he wanted to and play for the highly successful Manchester United Youth Cup team and Under-21 team.In April,1995 he played his first football league game against Leeds Untied.During 1995 and 1996,David became a regular member of the team and Manchester United won in both football seasons,with David scoring many goals.His goals made him a household name.In the first game of the 1996-1997 season,he scored a surprising goal from beyond the halfway line.Seeing the goalkeeper a little way out of his goal,Beckham became famous overnight.He continued to score astonishing goals,especially from free-kicks.The speed ofone of his shots was timed at 157 kph.He also had the ability to make the ball go from left to right,or right to left,whenever he chose.Goalkeepers were never sure where the ball was going,and it regularly ended up in the goal.1.Which word can take the place of the underlined word “passion” in Paragraph 1?A.Success.B.Interest.C.Prize.D.Skill.答案:B解析:词义猜测题。

GRAMMAR过去分词作宾语补足语过去分词作宾语补足语，表示被动的动作或完成的意义，宾语补足语与宾语之间常常存在逻辑上的动宾关系，即宾语是过去分词所表示的动作的承受者。

【归纳】可以接过去分词作宾语补足语的动词主要有：★find, watch, see, observe, look at, hear, listen to,notice等感官动词。

如：He tried the door and found it locked.We are pleased to see the problem settled so quickly.We can hear the windows beaten by the heavy rain drops.★make, get, have, keep, leave等使役动词。

如：They managed to make themselves understood in very simple English.It is wise to have some money put away for old age.He was very busy and often left his lunch untouched.★wish, like, want, order等表示“希望、想要、要求”的动词。

如：The boss wouldn’t like the problem discussed at the moment.I want my house painted white.【拓展】★have sth. done有两种解释：一是表示主语有意志的行为，have具有使役意义；二是表示“遭遇”、“经历”，此时过去分词所表示的动作是违背主语意愿的。

如：We ought to have her examined by a doctor.The old man had his leg broken in the accident.★介词with后也可接过去分词作宾语补足语，构成with复合结构。

Grammar and Writing目标导航Grammar——复习名词性从句用适当的连接词填空1．The first time that she had to write an essay, her tutor explained that she must acknowledge what other people had said if she cited their ideas, but that he mainly wanted to know what she thought! 2．At first, Xie Lei had no idea what she should say, but what surprised her was that she found herself speaking up in class after just a few weeks.3．What seemed strange before now appears quite normal to her.【自主发现】 当一个从句的性质相当于一个名词，并在主从复合句中作主语、宾语、表语或同位语时，这个从句被称为名词性从句。

语法知识一、主语从句(subject clause )主语从句就是在复合句中起主语作用的从句。

主语从句的连接词有：⎩⎨⎧从属连词：that ，whether ，if连接代词：what ，which ，who ，whom ，whose ，whatever ，whichever ，whoever ，whomever 连接副词：when ，where ，why ，how1．that 引导的主语从句(1)that 在主语从句中不充当成分，也没有含义，但通常不能省略。

That our team had won first prize made us very happy.我们队获得了第一名，这使我们很高兴。

高中英语人教版选择性必修第二册unit 1 Grammar表语从句(ThePredicative Clause)一、表语从句的定义：表语从句就是用一个句子作为表语，放在连系动词之后，充当复合句中的表语，用来说明主语是什么或者怎么样。

The problem is puzzling.主语连系动词形容词作表语The problem is when we can get a pay rise. 主语连系动词一个句子作表语一表语从句二、表语从句的构成：系动词+引导词+简单句What I want to say is that I am tired.三、表语从句的用法.可按表语从句的连系动词有：1).最常用连系动词：be(am; is/was; are/were)o一般在句子中译成：“ 日”7E ...China is no longer what she used to be.2).表变化的系动词：get; turn; go; fall; become; grow; come; run。

用法注意：在英语中，系动词一般只有一般现在时和一般过去时两种时态变化形式，没有其他时态变化形式。

但表变化的这类系动词除外，它们有各种时态变化。

It is becoming colder and colder. The food has gone bad.此处还需注意的是become和turn后接表职业的名词时冠词的有无：Two years later, he became a teacher.但Two years later, he turned teacher.另外，g。

表变化时一般指事情向消极、不好的方面转化。

3).所谓“感官动词”:look; sound; ta ste; smell; fbeL般它们在句子中译成:“・・・起来; ...上去”。

此类系动词为高考高频词。

The food tasted good.食物尝起来很香。

高中英语真题:高中英语Unit2Grammar导学案新人教版必修2英语中的分词有两种：现在分词和过去分词，兼有动词、副词和形容词的特征。

在句子中可以作定语，表语，宾语补足语和状语。

考点一现在分词的基本形式1．现在分词的一般式一般式所表示的动作与谓语动词所表示的动作一般同时进行。

如：They came in talking and laughing．他们谈笑着进来了。

Seeing nobody there，he turned off the lights．看到没人在那，他就把灯关了。

2．现在分词的完成式完成式表示的动作发生在谓语动词的动作之前。

如：Having cleaned the desks，we began reading．擦完了桌子后，我们便开始看书。

Having been surrounded for a month，the enemy had to give in．被包围一个月后，敌人不得不投降了。

3．现在分词的被动语态现在分词的被动语态分为一般式和完成式两种。

一般式表示一个被动动作正在进行。

或与谓语表示的动作同时进行。

完成式表示一个被动动作在谓语表示的动作之前已经完成了。

如： The building being built will be our school library．正在建造的那座大楼将是我们的校图书馆。

[例] ____ ，we were taken to Bee the library.A．We had been shown the classrooms B．Being shown the classroomsC．Having been shown the classrooms D．Having shown the classrooms[解析] 句意：我们先被领着看了教室，又被带去看图书馆。

首先，句子主语与show之间构成被动关系，因此可排除D项；A项为句子，需要加连词连接两个分句；B项相当于While we were being shown the classrooms，显然与后面的时间有冲突，故只有C项正确。
