《全新版大學(xué)英語(yǔ)》系列教材醞釀?dòng)谏鲜兰o(jì)末，誕生于新世紀(jì)初。
　　《全新版大學(xué)英語(yǔ)》系列教材依據(jù)現(xiàn)代外語(yǔ)教學(xué)理念，運(yùn)用多媒體、網(wǎng)絡(luò)等現(xiàn)代教育技術(shù)，立足本國(guó)，博采眾長(zhǎng)，完全自主編寫而成，是一套集紙質(zhì)教材（學(xué)生用書、教師手冊(cè)、教學(xué)輔助用書等）、多媒體課件（助學(xué)光盤、電子教案、題庫(kù)等）和網(wǎng)絡(luò)學(xué)習(xí)系統(tǒng)之大成的立體化教材。
　　教材的編寫宗旨是：遵循外語(yǔ)教學(xué)的客觀規(guī)律，滿足我國(guó)當(dāng)代大學(xué)生學(xué)習(xí)的實(shí)際需求，既適用于課堂教學(xué)又便于學(xué)生上機(jī)上網(wǎng)自主學(xué)習(xí)，既有利于鞏固語(yǔ)言基礎(chǔ)又能更好地培養(yǎng)學(xué)生較強(qiáng)的英語(yǔ)綜合應(yīng)用能力，尤其是聽說(shuō)能力，使他們?cè)诮窈髮W(xué)習(xí)、工作和社會(huì)交往中能用英語(yǔ)有效地進(jìn)行口頭和書面的信息交流。
　　教材按照《大學(xué)英語(yǔ)課程教學(xué)要求》編寫，供大學(xué)英語(yǔ)課程的一般要求和較高要求層次的教學(xué)使用。
　　教材編寫的指導(dǎo)方針是：充分汲取我國(guó)在外語(yǔ)教學(xué)中長(zhǎng)期積累起來(lái)的行之有效的經(jīng)驗(yàn)和方法，詳盡分析、研究中國(guó)學(xué)生在英語(yǔ)學(xué)習(xí)過(guò)程中以及在跨文化交際中經(jīng)常產(chǎn)生的問(wèn)題，學(xué)習(xí)、借鑒國(guó)外的教學(xué)理論和方法并根據(jù)我國(guó)的教學(xué)需要和現(xiàn)有條件加以消化、改造、吸收，自行規(guī)劃、設(shè)計(jì)，自行選材、編寫。為此，本教材采用了集中外多種教學(xué)法之長(zhǎng)的折中主義（eclecticism）教學(xué)理念。教材的編寫原則是：
　　1.倡導(dǎo)基于課堂教學(xué)+計(jì)算機(jī)／網(wǎng)絡(luò)的新型教學(xué)模式。教學(xué)中多媒體和網(wǎng)絡(luò)技術(shù)的引進(jìn)，既可改善語(yǔ)言教學(xué)環(huán)境和教學(xué)手段，又便于學(xué)生個(gè)性化學(xué)習(xí)和語(yǔ)言操練，有助于師生之間的溝通。但這一模式不應(yīng)一成不變，它應(yīng)隨著各校、各班級(jí)的具體情況而有所不同。此外，在利用現(xiàn)代信息技術(shù)的同時(shí)，應(yīng)充分發(fā)揮傳統(tǒng)課堂教學(xué)的優(yōu)勢(shì)，使之相輔相成。
　　2.提倡學(xué)生自主學(xué)習(xí)，同時(shí)主張充分發(fā)揮教師的主導(dǎo)作用。教師能否組織好教學(xué)——包括課堂教學(xué)和計(jì)算機(jī)輔助學(xué)習(xí)——是教學(xué)成敗的關(guān)鍵。除了課堂教學(xué)，教師更應(yīng)加強(qiáng)課外輔導(dǎo)，應(yīng)指導(dǎo)學(xué)生掌握正確的學(xué)習(xí)方法和學(xué)習(xí)策略。
　　3.在加強(qiáng)聽、說(shuō)的同時(shí)，充分兼顧對(duì)學(xué)生讀、寫、譯等應(yīng)用能力的培養(yǎng)，使學(xué)生能較好地掌握英語(yǔ)的書面語(yǔ)，這不僅是大學(xué)英語(yǔ)課程本身的性質(zhì)所使然，更是我國(guó)多數(shù)大學(xué)生今后學(xué)習(xí)、工作的需要。而學(xué)生的外語(yǔ)學(xué)習(xí)，特別是說(shuō)、寫方面的實(shí)踐活動(dòng)，必須以讀、聽一定量的語(yǔ)言素材輸入為前提。因此，必須通過(guò)課堂內(nèi)外、網(wǎng)上網(wǎng)下、大班小班、自學(xué)面授等一系列互動(dòng)互補(bǔ)的教學(xué)環(huán)節(jié)，才能全面提高學(xué)生的聽、說(shuō)、讀、寫、譯的應(yīng)用能力。
　　4.選用當(dāng)代英語(yǔ)的常見(jiàn)語(yǔ)體或文體的典型樣本作為素材。選文語(yǔ)言規(guī)范、富有文采、引人人勝、給人以啟迪；題材廣泛，以反映現(xiàn)實(shí)生活為主，科普內(nèi)容亦占有一定比重；體裁多樣；語(yǔ)體兼顧書面語(yǔ)和口語(yǔ)。

By definition. diet refers to the limited variety or amount of food that a person is allowed io eat for medical reasons or in order to lose weight. Though a mere diet. i.e. to limit the amount of food taken or to exclude certain foods may not work well on its own， many believe that they can lose weight effectively by going on a diet. There are hundreds of diets aiming at los-ing weight， such as low-fat diets， high-protein diets. low-calorie diets， high-fiber diets. water diets. vegan diets. fish diets， fruit-juice^diets and color diets. No matter whai it might be， all the diets， theoretically speaking. limit the intake of high-fat. high-calorie or;high-sugar foods so as to achieve the final goal of losing weight. The types of diets listed in the text are: low-fat diet: A low-fat diet works because it avoids high-fat foods such as pork or chicken skin.
　　for those high-fat foods often contain more calories. which will for sure lead to fatness. A low-fat diet highly suggests people to eat wholegrain rice. oats. fresh fruits and vegetables. lean white meat. skim milk and egg whites.
　　high-protein diet: A high-protein diet helps to lose weight because most high-protein foods are extremely low in carbs and saturated fat. Foods of this type in-clude chicken， turkey， lean meats and beef. fish and egg whites.
　　low-calorie diet: A low-calorie diet refers to any diet with a restricted intake of calories per day. Roughly speaking. a low-calorie diet aiming at weight loss allows a person to consume 1.500 to 1，800 calories per day.
　　high-fiber diet: Dietary fiber contained in foods help avoid or even halt lower di-gestive tract disorders such as constipation . diarrhea or both alternately. Foods containing more dietary fiber are whole-grain bread. fresh fruits (including the skin and pulp)，dried or stewed fruits (such as raisins). root vegetables (such as carrots. or potatoes)， and raw or fresh vegetables such as cabbage.
　　water diet: The water diet does not replace any other practicing diet at all. Instead. it is a supplementary diet. It is merely that you have to drink at least 8 glasses of water (64 ounces) throughout the day. Cold water is especially good for those who intend to lose weiglht for absorbs heat from your body and helps adjUSt the body's metabolism.
