為了獲得成品，它們還需要進(jìn)一步的精加工。Task2:EnglishforSpecialPurposesNotes③Secondaryprocessesremovemetalfromaworkpieceinordertoachieveaspecifiedshapeorconfiguration.

這句話對二次加工進(jìn)行了定義，可翻譯為“二次加工是將金屬從工件上切削下來的過程，目的是為了獲得特定的形狀或者結(jié)構(gòu)”。④Themostwidelyusedofthesemethodsischipremoval.

有屑切削是這些方法中應(yīng)用最廣泛的。Task3:Gramma動詞（verb）是英語詞匯中最重要、最復(fù)雜的。動詞有時態(tài)、語態(tài)、數(shù)的變化。1.及物動詞是指那些可以帶賓語的動詞。及物動詞必須帶賓語，否則視為錯誤。例如：Ilikecoffee.我喜歡喝咖啡。DidyouenjoythetriptoAustralia?澳大利亞之行你過得愉快嗎？Weneedsomecoffee.我們需要一些咖啡。動詞Task3:Gramma2.不及物動詞是指那些不能帶賓語的動詞，如rain,snow,fall,go,come,look,listen,wait等。不及物動詞要帶賓語時必須與特定的介詞連用，如lookat,listento,goto,cometo,waitfor,arriveat/in等。Hesuddenlyfelldownstairs.他突然摔下了樓梯。Wearrivedatthestationat7.我們七點鐘到了車站。動詞Task3:Gramma3.很多動詞既可用作及物動詞，又可用作不及物動詞；有些動詞在一種意義下是及物的，但在另一種意義下則是不及物的。Thetrainlefttenminutesago.（不及物）火車十分鐘前就開走了。Hetelephonedhiswifejustbeforehelefttheoffice.（及物）就在他離開辦公室之前，他給妻子打了電話。Hetalkedandsatdown.（不及物）他說完就坐了下來。DoyouspeakEnglish?（及物）你說英語嗎？動詞Task3:Gramma4.連系動詞必須后接表語（通常為名詞或形容詞）。這類動詞包括be,look,feel,become，get,seem等。Heistired.他累了。Shelooksill.她看上去不舒服。動詞Task3:Gramma5.助動詞是一種特殊動詞，它們不能單獨作謂語動詞，只有在與其他動詞連用時才能作謂語動詞。助動詞有have/has,be,shall,will,do等。Hehasjustleft.他剛走。Everythingwillcomeallrightintheend.一切最終會好起來的。Doyouwantabighouse?你想要一幢大房子嗎？動詞Task3:Gramma6.情態(tài)動詞主要用來表達(dá)懇求或請求（can,could,may,might）、可能性（can’t,could,may,might,must）、必要性（needn’t,must,oughtto,should）等。情態(tài)動詞與助動詞一樣，不能單獨作謂語動詞，只能與普通動詞連用。另外，情態(tài)動詞沒有語態(tài)的變化。動詞Task3:Gramma◆can/could/may/might用于懇求別人同意、允許。can用于朋友和同等地位的人之間；could和may是比較禮貌的形式，程度相同；might表示“猶豫”，是最禮貌的形式（例如懇求上級的同意和允許）。Can/Could/May/MightIuseyourtelephone,please?我可以使用您的電話嗎？Idon’twanttodisturbyou,butmightIcomeinforaminute?我不想打攪您，但我可以進(jìn)來待一會兒嗎？動詞Task3:Gramma◆情態(tài)動詞用于表達(dá)現(xiàn)在或?qū)淼目赡苄?，形式為：might/may/could/must+do/be+現(xiàn)在或?qū)頃r間。Hemay/mightcometomorrow.他明天也許會來。Hemustbesleeping.他肯定在睡覺。動詞Task4:Drills1.OralpracticeWorkinpai
