我们平时进行阅读时，阅读的速度会因所读的材料和阅读目的的不同而有所变化。例如，如果我们阅读的目的是要看懂一篇学术论文或一本教科书的某一章节，那我们的阅读速度显然要比看一份报纸慢一些。也就是说，阅读速度取决于阅读目的。此外，阅读速度和阅读理解之间也存在一定的辩证关系，即阅读速度快了，阅读理解会相应地有所降低。因此，我们的阅读速度要根据阅读目的和阅读材料的内容来定。
人们平时阅读一般的书刊资料时，并不总是要求弄清每一个细节和看懂每一个词。较常见的要求是正确理解文章的中心大意和抓住主要事实和有关细节。在这一前提下，我们进行快速阅读时，阅读理解的准确率不应低于70%。
要提高阅读速度，就要采取正确的方法，摒弃那些不利于提高阅读速度的不良习惯，如阅读读者嘴巴随视线的移动而逐词默读或轻轻地将每个词读出声来，因为这样会大大影响阅读速度。同样，用手指指着单词逐一地往前移也是不可取的，因为这和逐词默读一样也会使我们的阅读速度减慢。
《大学英语》系列教材（全新版）是一套依据全新的教学理念、全新的构思、全新的素材编写而成的供大学英语教学使用的系列教材。
本教材的宗旨是：在遵循现代外语教学理念、充分运用先进信息技术的基础上，注重为学生创造自主学习环境，强调个性化学习，全面培养学生的英语综合应用能力，尤其是听说能力，使他们在今后工作和社会交往中能用英语有效地进行口头和书面的信息交流。
《大学英语》系列教材自1986年的试用本问世以来，受到广大师生和英语学习者的青睐，先后被千余所院校采用，成为我国高校英语教学的首选教材，并荣获全国高等学校第二届优秀教材特等奖和国家教委高等学校第二届优秀教材一等奖。在这期间，教材曾数度修订，分别在1992年、1997年出版了正式本和修订本，较好地满足了当时教学的需求。然而，随着新世纪的到来，世界进入了经济全球化、科学技术一体化时代，英语作为当前国际上使用最为广泛的信息载体和交流工具，其重要性越发突出。近年来，由于我国的社会和经济迅猛发展、国际交往日益频繁，国家和社会对大学英语教学，对大学生的英语综合应用能力，尤其是听说能力，提出了更高和更迫切的要求。我国的大学英语教学面临着新的挑战。大学英语教学改革必须进一步深化。另一方面，我国的外语教学环境正逐步改善，多媒体、网络等现代教育技术的发展使得大学英语教学多样化、个性化有了可能。人们纷纷探求更适合我国国情的新的教学路子。许多教师已开始利用多媒体和网络技术进行英语教学，以弥补传统的课堂教学的不足，并取得成效。基于汁算机／网络+课堂教学的新型教学模式日渐形成。教材作为教改的一个重要方面，作为教学思想的一种载体，更应更新观念跟上形势，有新的作为。
正是在这种新形势下，上海外语教育出版社组织、策划了《大学英语》系列教材（全新版）的编写工作。在该社的全力支持、协调下，开展了广泛而深入的调研、论证工作，并在此基础上经过精心设计，认真编写出《综合教程》和《听说教程》的样课，在复旦大学等院校部分班级试用，同时征询了二十多个省市的数百所院校的意见，历经近三年时间的准备后，编写出这套全新的系列教材，更好地服务于新世纪我国的大学英语教学。

The Culture of "Lead Time"
Advance notice is often referred to in America as "lead time," an expression which issignificant in a culture where schedules are important. While it is learned informally, mostof us are familiar with how it works in our own culture, even though we cannot state therules technically. The rules for lead time in other cultures, however, have rarely beenanalyzed. At the most they are known by experience to those who lived abroad for sometime. Yet think how important it is to know how much time is required to prepare people,or for them to prepare themselves, for things to come. Sometimes lead time would seem tobe very extended. At other times, in the Middle East, any period longer than a week maybe too long.
How troublesome differing ways of handling time can be is well illustrated by the caseof an American agriculturalist assigned to duty as an attach6 of our embassy in a Latincountry. After what seemed to him a suitable period he let it be known that he would liketo call on the minister who was his counterpart. For various reasons, the suggested timewas not suitable; all sorts of cues came back to the effect that the time was not yet ripe tovisit the minister. Our friend, however, persisted and forced an appointment, which wasreluctantly granted. Arriving a little before the hour （the American respect pattern）, hewaited. The hour came and passed; five minutes —— ten minutes —— fifteen minutes. At thispoint he suggested to the secretary that perhaps the minister did not know he was waitingin the outer office. This gave him the feeling he had done something concrete and alsohelped to overcome the great anxiety that was stirring inside him. Twenty minutes ——twenty-five minutes —— thirty minutes —— forty-five minutes （the insult period） ！
