Before the Industrial Revolution, only a small percentage of the world's population was literate (有文化的). Literacy rates increased throughout the 19th century, as people started moving from the countryside to towns and cities for the job opportunities opening up in the newly industrialized societies. Many of these new jobs, especially the higher paying ones, required the ability to read and write. With the rise of universal education in almost all countries around the world, literacy rates have steadily gone up over the past hundred years.

But basic literacy is no longer enough. For years now, routine human tasks, that is, those

tasks that can well be described by a set of rules, have been taken over by technology substitution(代替) and automation(自动化). Many blue-collar manufacturing activities in assembly plans have fallen into this category. So have an increasing number of white-collar information-based activities, including record keeping and many kinds of administrative tasks.

Not surprisingly, our knowledge-based digital economy requires better educated workers with specific skills requirements. For example, we are surrounded by smart machines—cars, music players, TVs, video recorders, smart phones, PCs, the Internet, e-mail, the Web, e-commerce sites and on and on and on. They have become indispensable tools at work and at home. Digital literacy, the ability to deal with the sophisticated machines all around and use them effectively to help us address complex problems, has become a very important skill.

In general, people who are comfortable dealing with complexity are better able to handle more demanding, higher paying jobs. In our complex world, unanticipated situations often arise that we have not encountered before and thus require good problem solving skills. Similar cognitive skills are necessary to help us evaluate the options involved in making complex decisions.

A 2011 study by the McKinsey Global Institute projects a continuous demand for workers with at least a post-secondary education to meet the demands of business. According to McKinsey, employers are already having trouble filling positions requiring technical skills. Many workers will not necessarily have the skills needed for the jobs that are likely to most be in demand.

Moreover, as we look into the future, digital technologies will continue to be applied to activities requiring cognitive capabilities and problem solving intelligence that not long ago were viewed as the exclusive domain of humans. As a result, we will need to continually upgrade our skills in order to keep up with our increasingly smart machines and fast changing job requirements.

63. Why advanced literacy is necessary?

A. There are more human tasks which can be described by a set of rules.

B. There are more blue-collar manufacturing activities.

C. More routine human tasks have been taken over.

D. More record keeping and many kinds of administrative tasks appear.

64. Which of the following best describes what our digital economy needs?

A. Smart machines—cars, music players, TVs, the Internet, and so on.

B. Workers with good education and specific requirements.

C. Sophisticated machines all around.

D. Indispensable tools at work and at home.

65. From Paragraph 5, we can learn that McKinsey agrees that ________．

A. employers find it difficult to find skilled workers

B. employees have difficulty filling in the forms

C. workers surely have the skills needed for the jobs

D. all skills are in demand in the future

66. Which of the following is the best title for the passage?

A. World's Literacy Rates

B. The Development of Digital Technologies

C. Fast Changing Attitudes

D. Jobs and Lifelong Learning

数学培优教材第一讲函数的性质

高一年段数学培优教材第一讲函数的基本性质1 一、基本性质： 1. 函数图像的对称性（1）奇函数与偶函数：奇函数图像关于坐标原点对称，对于任意x D ∈，都有 ()()f x f x -=-成立；偶函数的图像关于y 轴对称，对于任意x D ∈，都有()()f x f x -=成立。（2）原函数与其反函数：原函数与其反函数的图像关于直线y x =对称。若某一函数与其反函数表示同一函数时，那么此函数的图像就关于直线y x =对称。若函数满足()(2)f x f a x =-，则()f x 的图像就关于直线x a =对称；若函数满足 f (x) + f (2a －x) = 2b ，则()f x 的图像就关于点(a ,b)对称。（3）互对称知识：函数()()y f x a y f a x =-=-与的图像关于直线x a =对称。 2．函数的单调性函数的单调性是针对其定义域的某个子区间而言的。判断一个函数的单调性一般采用定义法、导数法或借助其他函数结合单调性的性质（如复合函数的单调性）特别提示：函数(0)a y x a x =+ >的图像和单调区间。 3．函数的周期性对于函数()y f x =，若存在一个非零常数T ，使得当x 为定义域中的每一个值时，都有()()f x T f x +=成立，则称()y f x =是周期函数，T 称为该函数的一个周期。若在所有的周期中存在一个最小的正数，就称其为最小正周期。（1）若T 是()y f x =的周期，那么()nT n Z ∈也是它的周期。（2）若()y f x =是周期为T 的函数，则()(0)y f ax b a =+≠是周期为 T a 的周期函数。（3）若函数()y f x =的图像关于直线x a x b ==和对称，则()y f x =是周期为2()a b -的函数。（4）若函数()y f x =满足()()(0)f x a f x a +=-≠，则()y f x =是周期为2a 的函数。 4.几种特殊的抽象函数的周期：函数()y f x =满足对定义域内任一实数x （其中a 为常数）, ① ()()f x f x a =+，则()y f x =是以T a =为周期的周期函数； ②()()f x a f x +=-，则()x f 是以2T a =为周期的周期函数； ③()() 1 f x a f x +=± ，则()x f 是以2T a =为周期的周期函数； ④()()f x a f x a +=-，则()x f 是以2T a =为周期的周期函数； ⑤1() ()1() f x f x a f x -+= +，则()x f 是以2T a =为周期的周期函数. ⑥1() ()1() f x f x a f x -+=- +，则()x f 是以4T a =为周期的周期函数.
