教材分析本单元的内容是围绕播种，植树这一题材，让学生了解植树造林的意义。

日常交际用语运用了陈述目的基本表达法，同时在对话及课文阅读中使用了主要词汇的用法，如;shade, in order to, in fact, stop, cut down, known down等。

同时本单元出现的语法重点是复习被动语态及表示目的句型结构。

教学重点难点take, bring, carry, fetch这四个动词都有“带”的意思，但动作的方向不同。

1）take意为“拿去，带去”，如图所示：It’s going to rain. You’d better take your umbrella with you. 要下雨了，你最好带上雨伞。

2）bring意为“带来，拿来”，如图所示：Bring me the newspaper, please．请把报纸给我拿来。

3）carry意为“携带”，无方向性。

如：He always caries a small notebook in his pocket．他口袋里老是带着一个小笔记本。

4）fetch意为“去拿来”，如图所示：含有一去一来的意思。

如：People had to walk many kilometers in order to fetch wood．人们要砍柴得走很远。

burn v．－－烧毁，焚毁．烧伤；（由酸类）灼伤；燃烧（以取火或热）l）此词指正在燃烧的状态而不表示“点燃”的动作，“点燃”一词应是light。

I will keep the box in the shade so that the sun doesn’t burn the little plants．我将把盒子放在阴凉处以防太阳晒坏小苗。

The two men had their limits burning all night long in order that everyone might see how hard they were working on the Emperor’s new clothes. 这两个人点了一夜灯以便让大家知道他们赶做皇帝的新装是多么卖力。

2）对其过去式、过去分词有两种形式burned，burned或burnt，burnt。

但是过去分词burnt常用作adj.，如He took a burnt stick up from the ground．他从地上捡起一个燃烧过的棍子。

强调动作时多用burned，其后常接宾语。

They had burned all the old letters before they left．他们在离开前把所有的信都烧了。

feed．作为食物喂养；以……为食In fact they grow better if you feed them. 事实上如果你们喂养他们，他们就能生长得更好。

She feeds her baby on (with) cows’milk. =She feeds cows’milk to her baby.The sheep feed chiefly on grass. 羊主要以草为食。

soil, earth, ground ,land 和field的区别earth作“泥土”解，与soil通用。

它还可以作“地球，大地”解，相对于天空而言，如：He filled the hole with earth. 他用泥土填洞。

soil 指土壤，耕地，国土等。

Soil is earth in which flowers, trees and other plants can grow. 土壤是花草、树木及其他植物得以生长的泥土。

land 指相对于大海而言的“陆地”，也可以指土地、国土等。

After along journey, they found the rich land. 经过长途跋涉，他们找到了这块沃土。

ground主要指地面、地板（floor）,也可指田地（与land可通用），如：There is a large play ground in front of our building.在我们楼前有一个大操场。

field指田地、原野、场地（=ground）。

如：They are working in the fields. 他们正在地里干活。

The rest are left to grow even taller. 余下的被留下来以让它们长得更高。

1）the rest作“剩余部分，其余”讲。

它作主语时，其谓语动词的数要依据它所指代的名词的数来确定。

例如：The rest of the money was left to his son. 剩余的钱留给他儿子。

Only Tom is in the classroom. The rest of the students are still at play.只有汤姆在教室里。

其余的学生还在玩。

2）句中的副词even修饰比较级taller, 它没有实际意义，只起加强语气的作用。

可用来修饰形容词或副词比较级的词或短语还有much, far, still, rather, a lot, a great, deal, a little, a bit等。

例如：It’s a bit cold today. 今天有点冷。

His book is far more interesting. 他的书更加有趣。

so that he can catch the first bus.in order that he can catch the first bus.so as to catch the first bus.in order to catch the first bus.to catch the first bus.本单元重点的语法项目是表示目的的方式，下面将表示目的的几种方式归纳如下。

1、动词不定式（包括so as to，in order to）。

2、用so that和in order that引导目的状语从句，从“句中一般含有情态动词can，could，may，might等。

下面以“为了能赶上第一班车，他每天都起得很早”为例。

用否定结构，注意“不定式的否定结构在to前加not; so that/ in order that 只有在主句主语和从句主语一致的情况下可以换成so as to／in order to；in order to可放于句首，so as to 则不可）so that he can’t miss the first bus.in order that he can’t miss the first bus.so as not to miss the f[1] [2] [3] 下一页一、电子教案：题目：Unit 5 Silver Screen科目：英语授课老师：冯珍妮授课班级：高一（七）、（九）课时数：6（+1测验）教案相对应授课日期：2003年10 月25号——11月1号日期：10月24号电子教案设计老师：冯珍妮Teaching Plan for Unit 5高一年级冯珍妮1 ．Teaching goals and Learning goals:Language skills: ①Talk about films, famous actors and directors ②Practise making comments and giving opinions ③Learn to write about a film Language knowledge: ①V ocabulary: silver screen, drama, play role, actress get married, grow up, degree, in the beginning, make money, live with sb. , stepfather, director, make sb. famous, short film, script studio, career, take off, blockbuster, creature, outer space, make friends with, adult, cut…into pieces, dinosaurs, go wrong, follow-up, cruelty, win over, owe…to…, moving, stay away, take… place, run after, escape, lock, afford, fail, on air, together with, not just…but also ②Patterns:*She went to New York, where she started working as an actress. *She won her first Oscar as Best Actress. *This film quickly made him famous. *This was a film in which Spielberg used real actors instead of toys. *Many people who saw the film were afraid to swim in the sea when they remembered the scenes in which people were eaten by the shark. *He owes much of his success and happiness to his wife and children. *The reason why he could not go there was that his grades were too low. ③grammar*关系副词when, where, why引导的定语从句。
