Television is one of the greatest technological inventions of the twentieth century. A Scottish man called John Logie Baird invented it. Inventors in the USA and Europe were working on electronic television systems (系统) but Baird used a mechanical (机械的) system. In 1925, he was able to send the first black and white picture — of the head of a doll — from one end of his flat (公寓) to the other. He then used a local office boy, not the doll, and this teenager was the first person ever to appear on TV. Baird made the first television programmes for the BBC in 1929. These programmes had sound, not just pictures.

However, Baird’s system was very limited and basic. A totally electronic system was more popular and practical (实用的). The inventor of this electronic system was an American, Philo Farnsworth. In 1936, the BBC started using Farnsworth’s system because the picture was better than Baird’s.

Colour TV began in the USA in the 1940s but only a small number of people had colour televisions in their houses. They were very expensive. In Britain and the USA, the first regular (有规律的) colour TV programmes only began in 1967.

Now in the 21st century, we have digital (数字的) television. TV has changed a lot since the face of a boy appeared on TV in John Logie Baird’s flat!

1.Is television a great technological invention of the 20th century?（根据短文内容回答问题）

2.When did Baird make the first television programmes with sounds?（根据短文内容回答问题）

Television is one of the greatest technological inventions of the 20 century.　 A Scottish man called John Logie Baird invented it. Inventors in the USA and Europe were working on electronic television systems but Baird used a mechanical(机械的) system. In 1925, he was able to send the first black and white picture—of the head of a doll—from one end of his flat to the other. He then used a local office boy, not the doll, and this teenager was the first person ever to appear on TV.

In January 1926, Baird invited scientists to his flat and showed them his invention. He　 called it a “televisor”. Later that year, Baird started the world’s first TV station and gave it the name 2TV. In 1927, he sent images 730 kilometres from London to Glasgow using telephone cables(电缆). A year later, his company sent the first transatlantic(大西洋彼岸的) TV images from London to New York. Baird made the first television programmes for the BBC in 1929. These programmes had sound, not just pictures.

However, Baird's system was very limited and basic( 基本的). A totally electronic American system was more popular and practical. The inventor of this electronic system was an American, Philo Farnsworth. In 1936, the BBC started using Farnsworth's system because the picture was better than Baird’s.

More and more people had televisions after the Second World War. Colour TV began in the USA in the 1940s but only a small number of people had colour televisions in their houses. They were very expensive. In Britain and the USA, the first regular(有规律的) colour TV programmes only began in1967.

As one of the most well-known of the fantasy languages invented for science fiction film, television and book, and developed by J.R.R. Tolkien himself, Elvish is made up with several thousand words and different sentence structures.

Constructed languages (人造语言) like Elvish are real languages, made up of thousands of words created by fantasy writers, linguists and fans, with real language rules. While a widespread vocabulary is advantageous to a constructed language, there is a key differentiator (区分者) we can see between just a lot of words and real language: Grammar.

Grammar is what makes constructed languages like Elvish learnable by everyday superfans. Superfans of The Lord of the Rings have built websites and created dictionaries, apps and translators, to teach Elvish. They have also created online clubs where fans can discuss and even create new words based on the already existing vocabulary, and continue to study the language.

So what does it take to be a master of Elvish?

In learning Elvish, there are a couple of grammatical rules similar to those of the English language. For example, in order to make a verb past tense in English, you have to add an -ed, making wash, washed. Similarly in Elvish, in order to change the word for wash, which is allu, to the past tense then you have to add an -ne to the word. So washed is then translated to allune in past tense.

Nouns in Elvish are different in the way that the noun changes depending on how it’s used in a sentence, just like in Latin or Russian. For example, the word head in Elvish is CAS. However, if you duck your head, then the word changes to CARA. When mentioning something in your head, then it changes to CASSE. Tolkien’s attention to detail in creating the fantasy world used in The Lord of the Rings and The Hobbit, complete with multiple functioning (多功能的) invented languages, has attracted readers and movie viewers these years.

Elvish is only one of the many magical languages developed by J.R.R. Tolkien. Creating language for fantasy has proven to add to viewers and readers experiences. By transplanting their imagination to a new world, fans are able to learn the new language and speak Elvish with each other, much like their favorite characters.

1. Elvish is considered a real language because ______.

A. certain grammatical rules make the language learnable

B. it is made up with lots of words and sentence structures

C. characters in The Lord of the Rings use it to communicate

D. new words can be created based on already existing words

2.For the fans of The Lord of the Rings, ______.

A. Elvish is a language difficult to learn

B. there is no Elvish dictionary to refer to

C. Elvish adds to the novel’s attractiveness

D. they can even create new grammar for Elvish

3. Which of the following is TRUE about Elvish?

A. The translation of “washed” in Elvish is “allu”.

B. The form of a noun doesn’t change in Elvish.

C. Elvish and English share the same grammar.

D. Elvish is also used in the film The Hobbit.

4.The best title for this passage might be ______.

A. Elvish, a Magical Language

B. J.R.R. Tolkien, a Great Writer

C. The Hobbit, a Wonderful Film

D. Language, a Way to Communicate

TV was one of the greatest inventions in the 20th century.　 Nowadays，nearly every household has at least one TV set.

Television came into being based on the inventions and discoveries of many scientists. On April 7，1927，the first public television programme was broadcast in the USA. The signals were received on a very small screen. It was only about the size of a business card. The pictures were reddish and not clear.

In the 1930s, bigger screens appeared with black-and-white pictures. However，a snowy picture was the best many TV viewers could hope for. Often,　 they could only get one station，and only when the weather conditions were good.

When World War Ⅱ(1939-1945)began，the development of TV stopped.　 There were a very small number of TV sets in the hands of the public. By 1945，there were fewer than 7,000 working TV sets in the USA. A TV set cost about half the price of a car at that time.

The period after World War Ⅱ is considered the final birth of television.　 Families saved money during the war years，and wanted to buy a lot of things after the war.　 TV sets were soon put onto the "must have" list. 1950-1959 was an exciting period for television. Colour televisions and remote controls came out during this time. By 1955，the cost of TV sets came down a lot. Instead of being equal to half the price of a car, they were now just equal to the cost of a new set of tires. That marks the beginning of the booming age of TV.

1.Which is NOT true about the first public television programme?

A. It was broadcast in the UK.

B. It was broadcast in 1927.

C. The pictures were not clear.

D. It was shown on a small screen.

2.The underlined sentence in the last paragraph means 　　　　　 .

A. people liked TVs less than before

B. nobody wanted a TV in their home

C. every family wanted to buy a TV

D. people didn't know how to use a TV

3.Which of the following is TRUE about the early development of TV?

A. In the 1930s，TV signals became very easy to receive.

B. During World War，TV sets went into lots of families.

C. After World War II，TV was invented.

D. TV developed fast in the 1950s.

4.What's the main idea of the passage?

A. The birth of television.

B. The development of television.

C. How to invent television.

5.What does the word "booming" mean?

Michael Jordon is the greatest basketball player of all time. Once he was making a television advertisement, all he needed to do was to miss a shot.

For Michael, this was difficult. He had conditioned(定位) himself to succeed whenever he was throwing the ball. Every time he threw a basketball, it went in. Every time he tried to miss a shot, he couldn’t. In total, it took him over 20 attempts (尝试) before he missed a shot.

For Michael, success is a strong habit. It took him a lot of time to break it. Just like drinking, smoking and collecting things, success is also a habit. Once it is formed, it is difficult to break. Many people think that success is difficult to keep. They feel that it will be hard work and will need too much action and focus. The truth is that it is simply a habit, and as easy to keep as any other habit.

Spend some time making success a habit in your life. Once you have developed it, it is not something you want to change again.
