教學(xué)建議
能力訓(xùn)練
1．利用對(duì)話、課文，組織學(xué)生進(jìn)行聽(tīng)、說(shuō)、讀、寫(xiě)的訓(xùn)練。
2．利用新單詞、詞組及日常交際用語(yǔ)，組織學(xué)生造句、編對(duì)話、敘述課文、表達(dá)思想等。
德育教學(xué)
通過(guò)對(duì)話和課文的學(xué)習(xí)，喚起學(xué)生對(duì)大自然的愛(ài)心，使他們認(rèn)識(shí)到保護(hù)環(huán)境的重要性。
互動(dòng)活動(dòng)
1、聽(tīng)、讀 2、問(wèn)答練習(xí)3、造句4、編演對(duì)話5、討論6、復(fù)述課文7、講故事
聽(tīng)力建議
1．建議教師在聽(tīng)之前，大概介紹所聽(tīng)材料的內(nèi)容或背景知識(shí)，這樣學(xué)生們能夠抓住要點(diǎn)，同時(shí)教師也為了讓學(xué)生們理解得更清楚，也可提前把問(wèn)題寫(xiě)在黑板或讓學(xué)生們先看問(wèn)題，然后聽(tīng)磁帶。
2．在20課131頁(yè)的聽(tīng)力練習(xí)，主要內(nèi)容講解一對(duì)英國(guó)夫婦的農(nóng)場(chǎng)，教師在放磁帶之前，讓學(xué)生們看一看每道練習(xí)題的大致問(wèn)的內(nèi)容，放完一遍后，教師可問(wèn)一到兩個(gè)學(xué)生農(nóng)場(chǎng)的概況，然后教師根據(jù)問(wèn)題的內(nèi)容在分別放磁帶。
口語(yǔ)建議
1、教師堅(jiān)持用英語(yǔ)組織課堂教學(xué)的方向，盡量給學(xué)生創(chuàng)造英語(yǔ)的真實(shí)情景。幫助學(xué)生聽(tīng)懂課堂用語(yǔ)和日常交際用語(yǔ)。
2、本單元是對(duì)于表示目的一些交際用語(yǔ)，教師可以按以下程序：看、聽(tīng)老師演示→聽(tīng)錄音→ 訓(xùn)練學(xué)生典型句型→ 讀課文 → 學(xué)生運(yùn)用。
教材分析
本單元的內(nèi)容是圍繞播種，植樹(shù)這一題材，讓學(xué)生了解植樹(shù)造林的意義。日常交際用語(yǔ)運(yùn)用了陳述目的基本表達(dá)法，同時(shí)在對(duì)話及課文閱讀中使用了主要詞匯的用法，如;shade, in order to, in fact, stop, cut down, known down等。同時(shí)本單元出現(xiàn)的語(yǔ)法重點(diǎn)是復(fù)習(xí)被動(dòng)語(yǔ)態(tài)及表示目的句型結(jié)構(gòu)。
教學(xué)重點(diǎn)難點(diǎn)
take, bring, carry, fetch
這四個(gè)動(dòng)詞都有“帶”的意思，但動(dòng)作的方向不同。
1）take意為“拿去，帶去”，如圖所示：
It’s going to rain. You’d better take your umbrella with you. 要下雨了，你最好帶上雨傘。
2）bring意為“帶來(lái)，拿來(lái)”，如圖所示：
Bring me the newspaper, please．請(qǐng)把報(bào)紙給我拿來(lái)。
3）carry意為“攜帶”，無(wú)方向性。如：
He always caries a small notebook in his pocket．他口袋里老是帶著一個(gè)小筆記本。
4）fetch意為“去拿來(lái)”，如圖所示： 含有一去一來(lái)的意思。
如：People had to walk many kilometers in order to fetch wood．人們要砍柴得走很遠(yuǎn)。
burn v．－－燒毀，焚毀．燒傷；（由酸類）灼傷；燃燒（以取火或熱）
l）此詞指正在燃燒的狀態(tài)而不表示“點(diǎn)燃”的動(dòng)作，“點(diǎn)燃”一詞應(yīng)是light。
I will keep the box in the shade so that the sun doesnt burn the little plants．我將把盒子放在陰涼處以防太陽(yáng)曬壞小苗。
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. 這兩個(gè)人點(diǎn)了一夜燈以便讓大家知道 他們趕做皇帝的新裝是多么賣力。
2）對(duì)其過(guò)去式、過(guò)去分詞有兩種形式burned，burned或burnt，burnt。但是過(guò)去分詞burnt常用作adj.，如
He took a burnt stick up from the ground．他從地上撿起一個(gè)燃燒過(guò)的棍子。
強(qiáng)調(diào)動(dòng)作時(shí)多用burned，其后常接賓語(yǔ)。
They had burned all the old letters before they left．他們?cè)陔x開(kāi)前把所有的信都燒了。
feed．作為食物喂養(yǎng)；以……為食
In fact they grow better if you feed them. 事實(shí)上如果你們喂養(yǎng)他們，他們就能生長(zhǎng)得更好。
She feeds her baby on (with) cows’ milk. =She feeds cows’ milk to her baby.
The sheep feed chiefly on grass. 羊主要以草為食。
soil, earth, ground ,land 和 field的區(qū)別
earth作“泥土”解，與soil通用。它還可以作“地球，大地”解，相對(duì)于天空而言，如：
He filled the hole with earth. 他用泥土填洞。
soil 指土壤，耕地，國(guó)土等。
Soil is earth in which flowers, trees and other plants can grow. 土壤是花草、樹(shù)木及其他植物得以生長(zhǎng)的泥土。
land 指相對(duì)于大海而言的“陸地”，也可以指土地、 國(guó)土等。
After along journey, they found the rich land. 經(jīng)過(guò)長(zhǎng)途跋涉，他們找到了這塊沃土。
ground主要指地面、地板（floor）,也可指田地（與land可通用），如：
There is a large play ground in front of our building.在我們樓前有一個(gè)大操場(chǎng)。
field指田地、原野、場(chǎng)地（=ground）。如：
They are working in the fields. 他們正在地里干活。
The rest are left to grow even taller. 余下的被留下來(lái)以讓它們長(zhǎng)得更高。
1）the rest作“剩余部分，其余”講。它作主語(yǔ)時(shí)，其謂語(yǔ)動(dòng)詞的數(shù)要依據(jù)它所指代的名詞的數(shù)來(lái)確定。例如：
The rest of the money was left to his son. 剩余的錢留給他兒子。
Only Tom is in the classroom. The rest of the students are still at play.只有湯姆在教室里。其余的學(xué)生還在玩。
2）句中的副詞even修飾比較級(jí)taller, 它沒(méi)有實(shí)際意義，只起加強(qiáng)語(yǔ)氣的作用。可用來(lái)修飾形容詞或副詞比較級(jí)的詞或短語(yǔ)還有much, far, still, rather, a lot, a great, deal, a little, a bit等。例如：
It’s a bit cold today. 今天有點(diǎn)冷。
His book is far more interesting. 他的書(shū)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.
本單元重點(diǎn)的語(yǔ)法項(xiàng)目是表示目的的方式，下面將表示目的的幾種方式歸納如下。
1、動(dòng)詞不定式（包括 so as to，in order to）。
2、用so that和 in order that引導(dǎo)目的狀語(yǔ)從句，從“句中一般含有情態(tài)動(dòng)詞can，could，may，might等。下面以“為了能趕上第一班車，他每天都起得很早”為例。
He gets up early every morning
以上是用肯定句結(jié)構(gòu)。
用否定結(jié)構(gòu)，注意“不定式的否定結(jié)構(gòu)在to前加not; so that/ in order that 只有在主句主語(yǔ)和從句主語(yǔ)一致的情況下可以換成 so as to／in order to；in order to可放于句首，so as to則不可）
so that he can’t miss the first bus.
in order that he cant miss the first bus.
so as not to miss the first bus.
in older not to miss the first bus.
so that也可用來(lái)引導(dǎo)結(jié)果狀語(yǔ)從句。在so that引導(dǎo)的結(jié)果狀語(yǔ)從句中，謂語(yǔ)動(dòng)詞前不用情態(tài)動(dòng)詞，主從句間可有逗號(hào)隔開(kāi)。例如：
Everyone said no, so that the plan was dropped. 大家都反對(duì)，計(jì)劃就不再討論了。
cut down, cut in, cut off與cut out的區(qū)別
cut down意為砍倒，削減，指將樹(shù)砍倒或裁軍
to cut down a tree with an axe 用斧頭把樹(shù)砍倒
cut in 意為打斷，指從語(yǔ)言中打斷
Dont cut in while Im talking. 我說(shuō)話時(shí)別插嘴。
cut off意為“切斷、切下”指切斷電源，水源，煤氣等。
He cut off the gas when a fire breaks out.
cut out意為切下，刪下，指刪掉，剪下文章等。
He cut out an article from the newspaper.
