一. 課文內(nèi)容
Why↑, you may wonder, should spiders be our （弱讀）friends? Because they destroy '''so many insects, and '''insects include |some of the '''greatest enemies| of the human race. Insects would make it impossible（三個詞連讀 ，t變d，impossible 重讀，前兩個詞弱讀） for '''us（連讀，for弱讀） to live in the world; they would devour all our （連讀）crops and kill our（連讀） flocks and herds, if it were not for the protection we get from insect-eating（吃昆蟲） animals. We owe a '''lot to the birds and beasts| who eat insects| but all of them put together |kill only a '''fraction of the number |destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings.
Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a（連讀） glance, for | a '''spider always has eight legs and an '''insect never more than six.
How many spiders are '''engaged in this work on our behalf? One authority on spiders made a census of the spiders in grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like（弱讀） 6,000,000 spiders of different kinds |on a football pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the '''weight of all the insects destroyed by spiders in Britain in one year would be greater than the '''total weight of all the human beings in the country.

6. tell the difference 看出差別
7. Spiders are not insects, as many people think, nor even nearly related to them八竿子打不著
8. engaged in/on 忙于; 訂婚的;電話占線的
9. concensus共識
10. about
a. about與on表示“關(guān)于”：about是一般的“談及”，on則是有一定學(xué)術(shù)水平的“論及”?！纠纭縜 conversationabouthousekeeping有關(guān)家政的談話 / a book for childrenaboutMexico一本向兒童介紹墨西哥的書 / a lectureontheoretical physics一場關(guān)于理論物理的講課。所用介詞前面以及后面，兩邊的名詞的正式程度，在這里都需要綜合考慮在內(nèi)?！纠纭縜 novelabout(*on) love一本有關(guān)愛情的小說 / a filmabout(*on) Lincoln一部有關(guān)林肯的影片 / a thesison(*about) Lincoln一篇有關(guān)林肯的畢業(yè)論文 / a speechon(*about) a political subject一篇有關(guān)政治題目的演說 / a paperon(*about) the Holocaust一篇有關(guān)納粹大屠殺的論文。
b. 放在表示“知曉”、“感知”這類動詞后面，about比of表示了解得更為詳細(xì)具體。例如：know of somebody可能只是從書報電視上知道有此人，但know about somebody則是對此人有比較多的了解。表示“從不知到知”這一變化的learn of與learn about，也有類似區(qū)別
c. what X is all about是英語常用的詞組，表示X是什么一回事?！纠纭縏hat is what our job is all about.那就是咱們工作的內(nèi)容。也就是說，這里有一個公式：X is all about Y，其中X是個概括性的概念，Y則是它的較為具體的內(nèi)容。所以即使不用what，這個公式也成立。【例如】But if he does it any more, I shall certainly let him know that I seewhathe isabout.(Jane Austen, Pride and Prejudice, Chapter Six) 要是他再這樣，我一定要叫他明白我并不是個糊涂蛋（直譯：我一定要叫他明白我知道他的老底）。Successful truffle-making is about temperature control. 做軟塊糖要成功，關(guān)鍵在于控制好溫度。但是這個X is (all) aboutY的表達(dá)法，有些語言上保守的人士認(rèn)為不高雅，所以在比較正式的書面英語不常用。
11. football pitch足球場? basketball court籃球場
牛Beef Veal小牛肉 Ox公牛 Cow奶牛 Bull 紅牛
羊Sheep羊 Lamb小羊羔, goat公山羊與ram(沒有閹的)公羊
中文山羊綿羊、公羊母羊、老羊幼羊，都叫“羊”。英文卻是分得很仔細(xì)。lamb是“小羔羊”，有神圣可愛的意義。goat則是公山羊，往往有“好色”的含義。ram則也是公山羊，也有“好色”、“健壯”的含義。
pitch 音高（多來米）絕對音高:perfect pitch;足球、板球（cricket）、曲棍球（hockey ball）等運(yùn)動的球場；爭取拿到；If someone is pitching for something, they are trying to persuade other people to give it to them；通常指仔細(xì)瞄準(zhǔn)后用力投，擲，扔，拋； 搭[帳篷]; 扎營；If you pitch your tent, orpitch camp, you put up your tent in a place where you are going to stay
court:? (網(wǎng)球、籃球、羽毛球或壁球等的)球場
12. you may wonder 是這個疑問句的插入語。
常見的插入語還有：as you know, to be frank, in fact, generally speaking等等。
13. if it were not for the protection we get from insect-eating animals，這是一個非真實(shí)條件狀語從句，were表示虛擬語氣。
表示對過去的虛擬：If+過去完成時(had done sth), would/could have done...
表示對現(xiàn)在的虛擬：If+簡單過去時(did sth), would/could do...
14. owe a lot to 歸功于，感激

15. on our behalf 代表我們
on behalf of sb/on sb's behalf 代表某人
例句：On behalf of my colleagues and myself I thank you.
我代表我的同事以及我自己向你表示謝意.
三. 讀音糾正
1. 連讀： one hour（連讀）；
make it impossible（三個詞連讀 ，t變d，impossible 重讀，前兩個詞弱讀） for '''us（連讀，for弱讀）；
devour all our （連讀）crops and kill our（連讀） flocks and herd；
2. 弱讀
make it impossible（三個詞連讀 ，t變d，impossible 重讀，前兩個詞弱讀） for '''us（連讀，for弱讀）；
that is something like（弱讀） 6,000,000 spiders of different kinds |on a football pitch
3.? wonder /w?nd?/? 跟one 一樣，n也要發(fā)音? wander/wɑnd?/? 漫游
4.元音重讀，且/ɑ/? impossible? crop a lot /lɑt/
5. a lot of? ? /a lɑ d?v/
6. estimated/ei/動詞? estimate/?/ 名詞
7. con'tent滿意，'content目錄
四. 建議
1. 提早十分鐘不看文本聽課文
2. 英文語調(diào)變化跟重弱讀有關(guān)，跟中文語調(diào)變化導(dǎo)致意思變化不同
3. 我的問題 : 斷句
Because they destroy '''so many insects, and '''insects include |some of the '''greatest enemies| of the human race.
五. 練習(xí)
It has/t?s/been '''estimated that/?/? the '''weight of （連讀）''all the '''insects destroyed by ''spiders in ''Britain in one '''year | would be '''greater than the 'total '''weight of '''all the human ''beings in the country.
