It only makes him angry that you run. Nicholas did not answer, but cut to his left, up the beach and among the trunks of the palms, sprinting all the way because he had no way of knowing Ignacio was not right behind him, about to grab him by the neck. When he stopped it was in the thick jungle, among the boles of the hardwoods, where he leaned,.。 there was none. He drew a deep breath then and said, Well, that39。 he was not as strong as he had been only a day past, and bythis time next day he would probably be unable to outrun Ignacio. He should, he now realized, have eaten the monkey he had killed。s head。t mistaken after all, was I?I didn39。s a bit frightened of us. Have you ever talked to him, Nicholas?Today I did a little. He told me a story about a pet fish he used to have.Ignacio grew up all alone。t anyone,` just the machines. Now he doesn39。t other people around all the time. Remember that?a Only there. are other people around all the time。t he stay there?Did I tell you about the bird, Nicholas? She had been not listening again.What bird?I have a bird. Inside. She patted the flat stomach below her small breasts, and for a moment, Nicholas thought she had really found food. She sits in here. She has tangled a nest in my entrails, where she sits and tears at my breath with her beak. I look healthy to you, don39。ve swallowed so much I couldn39。m not really me, I39。ll bring you back some.When he reached the beach, Nicholas turned and walked slowly back in the direction of the dead fire, this time along the rim of dampened sand between the sea and the palms. He was thinking about machines.There were hundreds of thousands, perhaps millions, of machines out。t know. Two, three days ago. Ignacio gave me something.I39。t even wet, and do you know something, Nicholas? I39。m hollow and rotten and turning brown, dirt and old feathers, oozing away. Her beak will break through soon.Okay. Nicholas turned to go.I39。s how the world is.Not in Brazil, maybe, Nicholas said. He was trying to remember something about Brazil, but the only thing he could think of was a parrot singing in a straw hat from the view cartoons。t want anyone around him.Nicholas said slowly, Dr. Island said lots of people wouldn39。s emptie than it used to be. Where Ignacio was, there would have been Red Indian hunters two or three hundredyears ago。s Nicholas, and I called you. Then I thought I might be wrong, or that it might be Ignacio.Ignacio was chasing me. Maybe he still is, but h think he39。 had Dr. Island used that sound to speak to him? He walked toward it and found a little rill that threaded a way among the trees, and followedit. In a hundred steps it grew broader, slowed, and ended in a long blind pool under a dome of leaves. . Diane was sitting on moss on the side opposite him。 he remembered his effort to open a coconuthe had failed, but it was surely not impossible. His mind was hazy as to what a coconut might contain, but there had to be an edible core, because they were eaten in books. He decided to make a wide sweep through the jungle that would bring him back to the beach well away from Ignacio。 there was only the green hush.The light was still bright and strong and nearly, shadowless, but some interior sense told him the day, was nearly over, and he noticed that such faint shades as he could see stretched long, horizontal distortions of their objects. He felt no hunger, but he had fasted be39。.sound in an atmosphere silent and unwaked as Earth39。 words, realizing that they were a signal, he turned andbegan to run, splashing through the shallow water. Ignacio ran after him, much helped by his longer legs, his hair flying behind his dark young face, his square teetheach white as a bone and as big as Nicholas39。謝謝了！感謝幫助過(guò)我的同學(xué)們。她熱心的幫助和豐富的知識(shí)給了我極大的幫助，在畢業(yè)設(shè)計(jì)過(guò)程中，根據(jù)我自身的情況給予我了最大的空間。從系統(tǒng)測(cè)試的情況來(lái)看，該系統(tǒng)已經(jīng)達(dá)到了需求所定義的要求。因此，系統(tǒng)需要提供的功能有：作業(yè)上傳（將作業(yè)上載到指定地點(diǎn)，按上傳用戶 ID 進(jìn)行標(biāo)識(shí)） ，作業(yè)批閱（教師可對(duì)作業(yè)進(jìn)行批閱判分，批閱結(jié)果可讓被批閱用戶查閱） 。教案可能有各種形式，如htm，doc，ppt，avi 等，但在通常情況下，這些教學(xué)內(nèi)容都是靜態(tài)內(nèi)容，因此按類別及內(nèi)容分類在網(wǎng)站上發(fā)布即可。36結(jié) 論該系統(tǒng)基本符合原來(lái)的設(shè)想，系統(tǒng)模擬現(xiàn)實(shí)教學(xué)運(yùn)作模式，采用實(shí)名制。就可以獲得數(shù)據(jù)庫(kù)的連接 中文問(wèn)題在 JSP 語(yǔ)句中若不采取任何措施，則由 form 提交后的中文信息顯示在網(wǎng)頁(yè)上將會(huì)是亂碼，因?yàn)?HTML 網(wǎng)頁(yè)默認(rèn)的編碼方法為“ISO88591”. 所以，在 JSP 程序代碼中要使用“導(dǎo)引命令”來(lái)設(shè)置這個(gè) JSP 網(wǎng)頁(yè)的編碼方法為“GB2312”. 具體語(yǔ)句如下：%page contentType=”text/html。 } catch(Exception e) { ()。部分代碼如下： public static Connection getConnection()36 { Connection con=null?！nt c 。否則觸發(fā) MalformedURLException 異常,就說(shuō)明不支持此協(xié)議。使用 URL 編程,首先要構(gòu)造一個(gè) URL 對(duì)象,最簡(jiǎn)單的 URL 構(gòu)造器只是把絕對(duì)字符串形式的 URL 作為其唯一變量。} 課件集成系統(tǒng)的實(shí)現(xiàn)課件集成系統(tǒng)采用 JAVA 語(yǔ)言編寫(xiě),通過(guò) JavaBeans 實(shí)現(xiàn)數(shù)據(jù)庫(kù)訪問(wèn)邏輯,從數(shù)據(jù)庫(kù)中提出已注冊(cè)的課件,由操作者選擇合適的知識(shí)點(diǎn),由課件集成系統(tǒng)生成 JSP 文件后通過(guò) Web 服務(wù)器進(jìn)行發(fā)布。開(kāi)始閱讀傳送的文檔之前，首先要從 URLConnection（或 URL）對(duì)象中獲取輸入流InputStream，語(yǔ)句如下：BufferedInputStream bis=new BufferedInputStream(( ))。其中vnd 表示該應(yīng)用程序的制造者，必須將它包含在 MIME 類型里才能夠打開(kāi)該類型文檔。if(cookies==null){ String msg=您尚未登陸，請(qǐng)a href=b登陸/b/a后下載。 } ()。 (file)。 + file + 39。 (file)。8 題庫(kù)管理頁(yè)面第 節(jié) 上傳下載模塊 36頁(yè)面功能：設(shè)定上傳的文件大小值，文件類型和上傳所需要的文件夾說(shuō)明：根目錄默認(rèn)為 ch2，若進(jìn)行修改，需要到 中同時(shí)修改相應(yīng)的鏈接。查詢：根據(jù)用戶選擇的試題所屬內(nèi)容、試題類型進(jìn)行查詢，結(jié)果顯示在查詢結(jié)果顯示欄目中。7 在線測(cè)試頁(yè)面 頁(yè)面功能：題庫(kù)管理。具體界面如圖 450 ()。,39。,39。45 String image=(image)。 String content=(content)。 String title=(title)。部分關(guān)鍵代碼如下String name=(name)。5 留言查看頁(yè)面 頁(yè)面功能：用戶提交留言。具體界面如圖 4說(shuō)明：修改用戶名、密碼等個(gè)人資料。21圖 42 具體頁(yè)面 頁(yè)面功能：用戶控制面板，根據(jù)用戶權(quán)限的不同劃分顯示的具體內(nèi)容會(huì)有所不同。具體界面如圖 4同時(shí)，推薦論題可以讓老師更方便給學(xué)生推薦一些相關(guān)的知識(shí)，讓學(xué)習(xí)效果事半功倍。 頁(yè)面功能：用戶登陸，最上一欄為用戶導(dǎo)航，使得用戶能省時(shí)省力的進(jìn)入自己想要的頁(yè)面。在登錄網(wǎng)站系統(tǒng)中，有兩種用戶，一種是已注冊(cè)的用戶，一種是新用戶。不管是文件的上傳還是下載，通過(guò)界面?zhèn)鬟_(dá)給用戶的情況又分為：學(xué)習(xí)資料的上傳和下載（即資源共享，幫助學(xué)生更好的進(jìn)行課程學(xué)習(xí)）和作業(yè)的上傳和下載（作業(yè)的布置與提交） 。6 所示。3 論題信息表字段名稱 數(shù)據(jù)類型 長(zhǎng)度 含義id 字符 10 論題序號(hào)c
