The first public TV broadcasts were made in the USA in 1925. Many different people 1.contributed to the development of TV. In 1928, John Logie Baird constructed the first colour TV, but it was not until 1938 that the first colour TV programme was 2.broadcast. Most people have 3.benefited from satellite TV since satellites were used to broadcast TV in 1962. Satellites 4.allow everyone to receive the same broadcast at the same time. The history of sound recorders began in 1877, 5.when Thomas Edison made the first recording of a human voice on his 6.invention,_the record player. It had to be 7.wound up by hand and only played records two minutes long. By the late 1960s, portable cassette players were 8.developed,_along with video recorders. With the development of 9.digital technology, sound and video can now be stored on a PC, on the Internet, or using some form of portable 10.storage.

The dodo is among the most famous extinct creatures, and a_poster_child for humancaused extinction events. Despite its bad name, and the fact that the species was alive during recorded human history, little is actually known about how this animal lived, looked, and behaved. A new study of the only known complete skeleton (骨架) from a single bird takes advantage of modern 3D laser scanning (扫描) technology to open a new window into the life of this famous extinct bird.
The study was presented at the 74th Annual Meeting of the Society of Vertebrate Paleontology in Estrel, Berlin. Leon Claessens, Associate Professor at the College of the Holy Cross, and lead researcher on the study said that, “the 3D laser surface scans we made of the delicate dodo skeletons enable us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before. There are so many outstanding questions about the dodo bird that we can answer with this new knowledge.”
A complete dodo skeleton, found by an amateur collector and barber, Etienne Thirioux, on the island of Mauritius between 1899 and 1917, has remained unstudied, even though it is the only complete dodo skeleton from a single individual bird known to exist. All other skeletons are incomplete combinations, meaning that they are gathered from more than one individual. In addition, Thirioux constructed a second, partially combined skeleton, which contains many bones that also belong to a single bird. “Being able to examine the skeleton of a single, individual dodo, which is not made up from as many individual birds as there are bones, as is the case in all those other combined skeletons, truly allows us to appreciate the way the dodo looked and see how tall or fat it really was，” said Juilan Hume, of the Natural History Museum UK, a coauthor on the study.
The scans were performed on site in Durban, South Africa, and allow examination of the biology of this mysterious extinct bird in detail for the first time. Using the newest digital tools and techniques, the scans provide an insight into how the flightless dodo may have developed its giant size, and how it walked and lived in its forest home. According to Kenneth Rijsdijk, a biologist from University of Amsterdam, “the skull (颅骨) of the dodo is so large and its mouth so strong, that it is easy to understand that the earliest naturalists thought it was related to sharks and other birds of prey (猛禽), rather than the pigeon family.”

Ⅲ.任务型阅读
One of the hottest buzzwords in China right now is no doubt tuhao, a sarcastic, lighthearted term referring to rich people of little education, bad taste or lacking selfawareness.
This is yet another example of smart Chinese Internet users applying their creativity to an aged phrase and giving it new life and meaning. The term, which literally means “country bully”， has been around since ancient times, when it was used to refer to rich and powerful rural and lords.
However, the meaning of the word changed significantly when it was adapted a few years ago by Chinese players of the wildly popular computer game “World of Warcraft” to refer to rich players who spend big money buying powerful virtual weapons. Because they don't improve their skills by playing, these players are considered silly, uncultured, and unprofessional.
But that is not the end of tuhao's new life story. The renewed popularity of the term also coincides with (同时发生) the emergence (出现) of the Chinese “nouveau riche” — a generation of businessmen and women, property owners and entrepreneurs who have rapidly accumulated large amounts of wealth in recent years.
Similar to the many ragstoriches stories in human history, many Chinese billionaires who are on the global rich list do not come from welleducated or prestigious (声望很高的) backgrounds. Rather, they achieved financial success through powerful connections, smart investments, and by riding out China's economic boom. Many of them don't shy away from throwing their money around, yet we are often reminded of their lack of manners, taste and cultural sensitivity.
As a result, a term that was popularized in the gaming world has now also been introduced into daily conversation.
Trendy, young Internet users, who see themselves as the opposite of tuhao — not wealthy, but welleducated and cultured — have further popularized the term by using it in various comic situations. For example, the phrase “let's be friends, tuhao” became hot after it appeared in an online joke about a conversation between a rich young man and a wise monk. When Apple released its much anticipated iPhone 5S in September, Chinese Internet users accurately predicted the great popularity of the new goldencolored models among Chinese consumers, and named it “tuhao gold”， to make fun of the taste of rich Chinese people.
“Tuhao” — a latest buzzword in China
答案：1.Changes 2.ancient/old 3.referring 4.gaming
5．virtual 6.conversation/life 7.booming 8.known
9．Examples 10.tease/mock
