【正文】 Lesson64 The Channel Tunnel 海峽隧道s closest friends asked him to make a speech at a wedding reception. This is the sort of thing that Geoffrey loves. He prepared the speech carefully and went to the wedding with Jenny. He had included a large number of funny stories in the speech and, of course, it was a great success. As soon as he had finished, Jenny told him she wanted to go home. Geoffrey was a little disappointed by this but he did as his daughter asked. On the way home, he asked Jenny if she had enjoyed the speech. To his surprise, she said she hadn39。Lesson63 She was not amused 她并不覺得好笑Lesson62 After the fire 大火之后In future, astronauts will be required to descend from a spaceship while it is still in space and to return to it. The ability to do this will be necessary in future flights to distant planets. Scientists are now trying to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 o39。 As she walked away, I followed her out of the fair. she asked impatiently. 39。 As soon as I went outside, I forgot all about Madam Bellinsky because my wife hurried towards me. 39。At a village fair, I decided to visit a fortuneteller called Madam Bellinsky. I went into her tent and she told me to sit down. After I had given her some money, she looked into a crystal ball and said: 39。Our dog, Rex, used to sit outside our front gate and bark. Every time he wanted to e into the garden he would bark until someone opened the gate. As the neighbours plained of the noise, my husband spent weeks training him to press his paw on the latch to let himself in. Rex soon became an expert at opening the gate. However, when I was going out shopping last week, I noticed him in the garden near the gate. This time he was barking so that someone would let him out ! Since then, he has developed another bad habit. As soon as he opens the gate from the outside, he es into the garden and waits until the gate shuts. Then he sits and barks until someone lets him out. After this he immediately lets himself in and begins barking again. Yesterday my husband removed the gate and Rex got so annoyed we have not seen him since. if he picks a leaf, he will die. Many villagers believe that the tree has already claimed a number of victims. The vicar has been asked to have the tree cut down, but so far he has refused. He has pointed out that the tree is a useful source of ine as tourists have been ing from all parts of the country to see it. In spite of all that has been said, the touristshave been picking leaves and cutting their names on the treetrunk. So far, not one of them has been struck down by sudden death!cursed tree39。Lesson58 A blessing in disguise? 是因禍得福嗎？The Revealer39。Lesson55 Not a gold mine 并非金礦Lesson54 Sticky fingers 粘糊的手指********雪桃示范種植基地建設(shè)項(xiàng)目前期階段于2010年11月開始，2011年2月結(jié)束，項(xiàng)目建設(shè)階段從2011年3月開始，2012年11月結(jié)束，并投入試運(yùn)營(yíng)，總建設(shè)期限兩年。項(xiàng)目前期工作包括立項(xiàng)、可行性研究和評(píng)估。二、 管理機(jī)構(gòu)設(shè)置方案 項(xiàng)目組織機(jī)構(gòu)及管理結(jié)構(gòu)項(xiàng)目法人副廠長(zhǎng)種植技術(shù)員80戶果農(nóng)苗圃示范園 第十一章 項(xiàng)目實(shí)施進(jìn)度一. 建設(shè)工期********雪桃示范種植基地建設(shè)項(xiàng)目總建設(shè)工期為2年二. 項(xiàng)目實(shí)施進(jìn)度安排項(xiàng)目實(shí)施進(jìn)度分為兩個(gè)階段進(jìn)行。第十章 經(jīng)營(yíng)管理一、 項(xiàng)目法人組建方案項(xiàng)目實(shí)行法人負(fù)責(zé)制，下設(shè)一名副廠長(zhǎng)，聘請(qǐng)兩名有經(jīng)驗(yàn)的雪桃種植技術(shù)員，實(shí)行垂直管理，責(zé)任到人。（4）結(jié)合現(xiàn)有地形及建筑物造型種植綠化帶、綠地，栽種各類花卉、常綠喬木、灌木、花壇，形成喬、灌、草相結(jié)合的田園景區(qū)，建成環(huán)境優(yōu)美的企業(yè)，綠化率達(dá)到90%以上。（3）燃煤采用低硫低灰份燃煤，外排廢氣必須達(dá)到《大氣污染物綜合排放標(biāo)準(zhǔn)》（GB16297——1996）表2二級(jí)標(biāo)準(zhǔn)，確保達(dá)標(biāo)排放，使用期噪聲達(dá)到《工業(yè)企業(yè)廠界噪聲標(biāo)準(zhǔn)》（GB12348——90）Ⅱ類標(biāo)準(zhǔn)。運(yùn)營(yíng)期環(huán)境保護(hù)措施（1）生活垃圾設(shè)固定堆放點(diǎn)，根據(jù)垃圾的不同種類，設(shè)置不同的垃圾收集路線和垃圾收集方式，當(dāng)天運(yùn)送到環(huán)衛(wèi)部門指定地點(diǎn)，進(jìn)行統(tǒng)一集中處理。三、 環(huán)境保護(hù)設(shè)施與投資建設(shè)期環(huán)境保護(hù)措施（1）對(duì)于施工揚(yáng)塵，應(yīng)采取定期噴灑水；運(yùn)輸?shù)缆吠ǖ兰皶r(shí)清掃、沖洗，運(yùn)輸車輛進(jìn)入施工場(chǎng)地應(yīng)低速行使或限速行使，減少汽車行使揚(yáng)塵；所有來(lái)往施工地的多塵物料均應(yīng)用帆布覆蓋，避免起塵原材料的露天堆放；施工過(guò)程中應(yīng) 采用商品（濕）水泥和水泥預(yù)制件 , 盡量少用干水泥等措施 , 確保環(huán)境空氣質(zhì)量達(dá)到《環(huán)境空氣質(zhì)量標(biāo)準(zhǔn)》 GB30951996 二級(jí)標(biāo)準(zhǔn)，減少對(duì)外環(huán)境的影響。（3）噪聲生產(chǎn)產(chǎn)生的噪聲及交通噪聲農(nóng)藥殘留對(duì)環(huán)境的影響為了杜絕農(nóng)藥殘留對(duì)環(huán)境的影響，我公司對(duì)種植基地的生產(chǎn)將嚴(yán)格施用農(nóng)家肥等有機(jī)肥，探索使用生物防治病蟲害，做到最大限度地減少農(nóng)藥殘留對(duì)環(huán)境的影響。項(xiàng)目運(yùn)營(yíng)期的環(huán)境影響分析（1）廢水主要為日常生活污水、清潔衛(wèi)生污水，生產(chǎn)、生活污水量按用水量的85%計(jì)算。（2）揚(yáng)塵主要為建筑工地的揚(yáng)塵。聲環(huán)境質(zhì)量現(xiàn)狀據(jù)多年監(jiān)測(cè)資料，項(xiàng)目地區(qū)聲環(huán)境符合《城市區(qū)域環(huán)境噪聲標(biāo)準(zhǔn)》GB309693II類。生產(chǎn)生活用水均為達(dá)到生活用水標(biāo)準(zhǔn)的水。二、 水耗指標(biāo)分析耗水量是指在輸水、用水過(guò)程中，通過(guò)蒸騰蒸發(fā)、土壤吸收、產(chǎn)品帶走、居民和牲畜飲用等各種形式消耗掉，而不能回歸到地表水體或地下含水層的水量。通過(guò)采用種子加工技術(shù)，減少水分消耗，降低灌溉用水的技術(shù)或措施；四是平衡施肥措施。通過(guò)改變田間的平整度，或改變土壤結(jié)構(gòu)的方法以減少土壤水分流失或散失的措施。三、 場(chǎng)內(nèi)運(yùn)輸設(shè)施及設(shè)備場(chǎng)內(nèi)運(yùn)輸設(shè)施及運(yùn)輸設(shè)備一覽表序號(hào)設(shè)施（設(shè)備）名稱單位數(shù)量規(guī)格型號(hào)備 注1道路km毛 路3貨運(yùn)小卡車輛4農(nóng)用車輛5拖拉機(jī)輛6自卸式人力車輛自 制第八章 節(jié)水措施一、 節(jié)水措施總體而言，項(xiàng)目區(qū)域水資源比較充沛，但是還是要在以下幾個(gè)方面采取節(jié)水措施：一是土壤保墑措施。主要技術(shù)經(jīng)濟(jì)指標(biāo)表序號(hào)項(xiàng)目名稱單位數(shù)量備注1規(guī)劃用地面積畝2種植面積畝3現(xiàn)有建筑面積m2（1）倉(cāng)儲(chǔ)面積m2（2）辦公居住面積m24道路m5區(qū)內(nèi)溝渠m6工程總投資萬(wàn)元二、 運(yùn)輸 場(chǎng)外年運(yùn)輸量及運(yùn)輸方式********雪桃示范種植基地建設(shè)項(xiàng)目產(chǎn)品主要銷售給怒江州境內(nèi)的水果市場(chǎng)，部分銷售給昆明、大理、保山及楚雄外地州，產(chǎn)品數(shù)量供不應(yīng)求，產(chǎn)品總運(yùn)輸量經(jīng)測(cè)算為1652噸，主要采用氣調(diào)保鮮運(yùn)輸車由********物流有限責(zé)任公司自主送貨方式運(yùn)輸。二、 原材料供應(yīng)雪桃的供苗是由麗江園藝站提供，而且同時(shí)與該站達(dá)成了長(zhǎng)期技術(shù)指導(dǎo)意向，企業(yè)將派員到麗江培訓(xùn)學(xué)習(xí)，并請(qǐng)麗江園藝站技術(shù)專家技術(shù)指導(dǎo)企業(yè)育苗。3. 氣調(diào)貯藏保鮮庫(kù)：為了配合優(yōu)質(zhì)水果、蔬菜的貯藏，減少損失，為僅季節(jié)銷售打下扎實(shí)的存庫(kù)基礎(chǔ)，擬投入180萬(wàn)元建設(shè)一個(gè)200T氣調(diào)貯藏保鮮庫(kù)。自動(dòng)檢測(cè)控制系統(tǒng)其主要作用是：對(duì)氣調(diào)庫(kù)內(nèi)的溫度、濕度、OCO2氣體進(jìn)行實(shí)時(shí)檢測(cè)和顯示，以確定符合氣調(diào)技術(shù)指標(biāo)要求，并進(jìn)行自動(dòng)調(diào)節(jié)，使之處于最佳參數(shù)狀態(tài)，一般由（溫度、濕度、OCO2）傳熱器、控制器，計(jì)算機(jī)及最樣管，閥等組成，整個(gè)系統(tǒng)由一臺(tái)中央控制計(jì)算機(jī)實(shí)現(xiàn)運(yùn)距離實(shí)監(jiān)控，即可獲取各個(gè)分庫(kù)的OCO溫度、濕度數(shù)據(jù)，顯示運(yùn)行曲線，自動(dòng)打印記錄和啟動(dòng)或關(guān)閉各系統(tǒng)，同時(shí)還能根據(jù)庫(kù)內(nèi)物料情況隨時(shí)改變控制參數(shù)。加濕系統(tǒng)與普通果蔬冷庫(kù)相比，由于氣調(diào)貯藏果蔬的貯藏期長(zhǎng)，果蔬水分蒸發(fā)較高，為抑制果蔬水分蒸發(fā)，降低貯藏環(huán)境與貯藏果蔬之間的水蒸氣氣壓差，要求貯藏環(huán)境有最的相對(duì)濕度，這對(duì)于減少果蔬的干耗和保持果蔬的鮮脆有著重要的意義，加濕方式有：①地面充水加濕；②冷風(fēng)機(jī)底盤注水；③噴霧加濕；④離心霧化加溫；⑤超聲霧化加濕。氣調(diào)系統(tǒng)要使氣調(diào)庫(kù)達(dá)到所要求的氣體成分并保持相對(duì)穩(wěn)定，除了要有符合要求的氣密性庫(kù)體外，還要有相應(yīng)的氣體調(diào)節(jié)設(shè)備，閥門所組成的系統(tǒng)，整個(gè)氣調(diào)系統(tǒng)包括制氧系統(tǒng)，CO2脫除系統(tǒng)，乙烯脫除系統(tǒng)溫度，濕度及氣體成分自動(dòng)檢測(cè)控制系統(tǒng)。裝配式氣調(diào)庫(kù)圍護(hù)結(jié)構(gòu)選用彩鍍聚氨脂夾心板組裝而成，具有隔熱、防防氣密的作用，該類庫(kù)建筑速度快，美觀大方，但造價(jià)高，是目前國(guó)內(nèi)外新建氣調(diào)庫(kù)最常用的庫(kù)型，氣調(diào)庫(kù)采用專門的氣調(diào)門，該門應(yīng)具有良好的保溫性和氣密性。氣調(diào)庫(kù)體主要由氣密層和保溫層構(gòu)成。氣調(diào)庫(kù)的構(gòu)成：一般由氣密庫(kù)體，氣調(diào)系統(tǒng)，制冷系統(tǒng)，加濕系統(tǒng)，壓力平衡系統(tǒng)及溫度、濕度、OCO2，氣體自動(dòng)檢測(cè)系統(tǒng)構(gòu)成。氣調(diào)貯藏所在適宜低溫條件下，通過(guò)改變貯藏環(huán)境氣體成分，相對(duì)溫度，最大程度地創(chuàng)造果蔬貯藏最佳環(huán)境，其效果表現(xiàn)在以下方面，氣調(diào)貯藏營(yíng)造的低氧（一般O2含量為1%—5%），適量的CO2濃度能有效的抑制呼吸作用，減少果蔬中營(yíng)養(yǎng)物質(zhì)的損耗，同時(shí)抑制病原菌的滋生繁殖，控制某些生理病害的發(fā)生，消除貯藏環(huán)境氣體中的乙烯，以抑制其對(duì)果蔬的催熟作用，延緩后熟的衰老過(guò)程，增加環(huán)境氣體中的相對(duì)濕度，以降低果蔬的蒸騰作用，從而達(dá)到果蔬長(zhǎng)期貯藏保鮮的目的，因此，經(jīng)過(guò)氣調(diào)貯藏的果蔬具有以下特點(diǎn)：①很
