1It is common knowledge that The Titanic, that unsinkable ship launched in 1912, did indeed sink. 2The horror of what the passengers experienced has been explored in books, on film, and on the stage. 3Some did live to recount that dreadful day when the queen of the seas hit an iceberg near Newfoundland and a hole was sliced in the hull of the magnificent craft. 4Could the accident have been prevented? 5Could the lives of the passengers and crew who were lost have been saved by having a more watchful first mate? 6Recent diving explorations to the remains of the ship revealed some startling news: the ship was not destined to sink despite hitting the iceberg. 7The findings suggest the real cause of the sinking of The Titanic was due to faulty rivets, or bolts, holding the sea doors shut. 8When the ship hit the iceberg, the rivets loosened and permitted water to enter the hull, very likely causing the ship to sink.

1For many years, researchers have examined possible reasons for the overall poor educational achievement of students from America's working-class families. 2The language in the home environment of these families may be a factor. 3The home environment often differs from the school environment which the children must later enter. 4The manner in which language is used in working-class homes affects how children write and respond to questions in school. 5Children from poorer homes often do not use complex sentences to communicate; instead, they use short, direct sentences and responses and a simple vocabulary. 6Some families are more authoritarian in nature, and children in these homes are not encouraged to speak freely or express their ideas through language. 7To do so would be to challenge the authority of the parents. 8Therefore, when these children are encouraged to speak and to write freely in school, they are not comfortable. 9They have been conditioned to believe their ideas are not important. 10Conversation and language use are quite different in schools, and even if children do engage in more elaborate language use, they may have little opportunity to practice their new language skills in their home environment.

1Making the decision to purchase a car is an important one. 2There are many factors to consider, and it is wise to follow some important steps to insure that you are buying the car that is right for you.

3The first step in the car-buying process is to decide how much you want to spend and what types of cars you can afford. 4Remember that even after the initial cost, maintenance and gas are expensive, so be sure to consider all additional costs in your budget. 5Make a plan for yourself based on your income, loans you might need, and how much you can afford for monthly payments. 6After you have a budget, decide what type of car is right for you: the model, make, features, and color you prefer. 7To help make these decisions, use car-buying guides, study safety reports, and visit dealerships. 8After you have narrowed your choices, start shopping. 9Newspaper ads are a great place to look for new and used vehicles, as is visiting selected dealerships. 10The Internet is one of the best places to look since it provides listings from dealers and individual sellers. 11The last step is actually buying the car you have found.

12Buying your own car, especially if it is your first one, can be an exciting and rewarding experience. 13However, it can also be an expensive one; so it is smart to give careful thought to what buying a car involves before actually making your purchase.

1Each new year brings the Super Bowl, an American tradition. 2This tradition began on January 15, 1967 when the National Football League's Green Bay Packers romped over the American Football League's Kansas City Chiefs 35-10 in Memorial Coliseum in Los Angeles. 3The championship game boasted over 60,000 people in attendance, and it seemed to spark a competitive flame in Americans. 4Americans loved football!

5The event, thanks to television, has now become an American cultural icon. 6Those not lucky enough to be in attendance for week-long pre-game parties throw their own Super Bowl parties and stay glued to giant-screen television sets at home. 7Americans gladly spend freely for Super Bowl merchandise, and advertisers spend millions for precious advertising time during the game. 8The ads themselves have even become cultural icons: each year the companies buying air time for this event find their ads previewed and rated by loyal fans. 9The ads have now become the topic of pre and post-game television talk shows.

10That first game in 1967 between two leagues was more than a championship football game. 11That first game set in motion a merchandising and marketing super event, one that Americans seem to have institutionalized.
