Throughout history, people have been interested in knowing how languages first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about 3,000 languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers.

There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 yeas ago.

Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even died out completely. About 1,000 years ago, English was a little-known relative of German spoken on one of the borders of Europe.

If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can’t understand speakers from other parts.

C. the difference between the old and today’s Chinese

D. the form of a language used in one part of the country

Barcodes(条形码) aren’t given much thought by the majority of consumers, but these codes were fairly recently applied in a working fashion in 1970.

A small food store owner decided one day that keeping records of the inventory(存货) of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem and began working on a solution involving an automatic way of keeping track of items that had been sold. Sliver and a group of students from the institute realized their answer in the form of ultraviolet light (紫外线), ink and a scanner.

The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace（寻常的事）in grocery stores, these two problems had to be solved.

The patent (专利) for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact, it took three years for the patent agency to grant their invention patent for the barcode, occurring on 7^th October, 1952.

Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticized, as there was no central mechanism for controlling uniformly（统一地）coded items. In 1970, Logicom developed the Universal Grocery Products Identification code( UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh’s superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared(升温) ever since, and is obviously now commonplace in all types of stores worldwide.

1.What is stressed in the second paragraph?

A．The heavy work of store owners.

B．The function of ultraviolet light, ink and a scanner.

C．The origination of barcodes.

D．Bernard Sliver’s education background.

2.Which of the following was NOT a drawback of Sliver’s system?

A．It was expensive to be applied on a large scale.

B．It was a laborious process.

C．The system was not stable.

D．It lacked a central mechanism.

3.The popularity of the barcode rose quickly after .

A．1948 B．1952 C．1966 D．1970

4.What is the purpose of the text?

A．To tell people that failure is the mother of success.

B．To praise scientists’ efforts in making people’s lives easier.

C．To describe shop owners’ opinions of barcodes.

D．To provide information about the development of barcodes.

In an age dominated （控制的） by new media and the Internet, there are so many alternative ways of learning．Gone are the days when, if we couldn't make it into a classroom, the only real option was to pick up a book, or when audio materials consisted of bad quality cassettes or sporadic（时有时无的） radio and TV programmes．With the appearance of broadband access to the web, we have a whole new learning domain （统领） at our fingertips．Sophisticated learning materials in the form of text or high-quality audio are now available at the touch of a button, and tests and assignments can be submitted （进行） and marked online．Questions and learning, studying away from the classroom has never seemed easier．Yet many teachers would argue that face-to-face contact between teachers and students is an essential part of the language learning experience．Enter the concept of blended （融合的） learning, an approach to education which seeks to combine the best of new technology and actual human contact．

Advocates of blended learning argue that an approach to study which combines the benefits of new technology with the best aspects of face-to-face （often abbreviated to F2F） teaching, will achieve better results．For example, there are some aspects of study, like practical sessions, dealing with more subjective questions, or meeting the needs of an individual student, which require face-to-face human interaction, whereas the more mechanical aspects of learning, such as answers to clear-cut questions, can be managed simply and effectively in a remote environment using new technology．

Blended learning approaches have proven especially appropriate in language learning．For example, in an ELT （English Language Teaching ） environment, a simple scenario （剧情概要） might be a classroom session where a teacher asks a group of students to use a wiki to create a text． Students then go away and compose and edit the text remotely．During the next F2F session, the teacher express his opinion about their work．

1.What is the main idea of this passage?

A．Blended learning is an effective learning approach．

B．More and more people will use Internet-based learning materials,

C．There are so many different ways of learning for people to choose in today's world．

D．Blended learning methods have proven to be effective except in language learning．

2.Which of the following aspects of study doesn't require face-to-face interaction between teachers and students?

A．Practical sessions．

B．Tackling the needs of an individual student．

C．Dealing with more subjective questions．

D．Providing answers to clear-cut questions．

3.It can be inferred from the passage that ______．

A．the radio and TV in the past were of poor quality

B．people do not get audio materials through cassettes nowadays

C．it was not convenient for people to leam outside a classroom in the past

D．it was difficult to find a classroom with good learning conditions in the old days

4.Which of the following can be best describe the writer's attitude towards blended learning?

Until the twentieth century cigarettes were not an important threat to public health. Men used tobacco mainly in the form of cigars. Most women did not use tobacco at all.

The cigarette industry began in the 1870s with the development of the cigarette manufacturing machine. This made it possible to produce great numbers of cigarettes very quickly, and it reduced the price.

Today cigarette smoking is a widespread habit. About forty-three percent of the adult men and thirty-one percent of the adult women in the United States smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit. Seventy-five percent of the male population and forty-six percent of the female population have smoked cigarettes at some time during their lives, but twenty-six percent of these men and eleven percent of the women have stopped smoking. The number of persons who have given up smoking is increasing.

Men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is the age group 24-44. Income, education and occupation all play a part in determining a person’s smoking habits. City people smoke more cigarette than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, ___________, he is likely to smoke more packs of cigarettes per day.

The situation is somewhat (有点) different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower educational groups. These more highly educated women tend to smoke more heavily.

Among teenagers the picture is similar. There are fewer teenager smokers from upper-income and well-educated families. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.
