The Statue of Liberty and the Liberty Bell

In America, two monuments symbolize the ideal of freedom that the country holds dear. The Statue of Liberty and the Liberty Bell represent freedom in different ways. The Statue of Liberty brings about feelings of hope for freedom to immigrants who enter the USA. The Liberty Bell commemorates the struggle for freedom that marks America’s past.

In the past, the Statue of Liberty was the first thing people saw when their boats approached America. The statue stands over 45 meters tall. It was given as a gift to the United States in 1885 by France. The date was chosen to mark the centennial of the establishment of the United States.

The sculpture is made of copper. The internal structure was designed by Gustave Eiffel, who also designed the famous tower bearing his name in Paris. The statue is located on Liberty Island in New York Harbor. In her right hand Lady Liberty holds a torch. It is meant to light the way of freedom across the land. In her left hand she holds a tablet with the date 1776 inscribed on it. This is to commemorate the year America declared its independence from Great Britain. It is possible to go inside the statue. Many people enjoy climbing the stairs to enter her head and torch.

The Liberty Bell is located in Philadelphia, Pennsylvania, and is most famous for being rung on July 8, 1776. It was rung to summon citizens for the first public reading of the Declaration of Independence. It was also rung in 1774 to announce the opening of the first Continental Congress. Inside the bell is cast an inscription from the Bible’s Leviticus 25:10. This passage states, “Proclaim liberty throughout all the land unto all the inhabitants thereof.” The Liberty Bell was originally cast in 1752. It got its famous crack in 1753 the first time it was rung.

In 1965, the FBI uncovered a plot by terrorists to destroy the Statue of Liberty and the Liberty Bell. But these attacks on the symbols of freedom were quickly stopped.

Read the text about Alexander Graham Bell and do the tasks:

Alexander Graham Bell is widely known as inventor of the first telephone. He was born on March 3rd, 1847 in Edinburgh, Scotland. When he was 23, Bell emigrated to Canada with his parents and the next year moved th the United States to teach deaf-mute children. With his colleague Thomas Watson, Bell worked very hard on the experimentation to invent devices such as the harmonic telegraph ( used to send multiple messages over a single wire) and phonautograph ( used to draw the shape of the sound waves). The first telephone communication was said to have happened between Bell and Watson in 1876 while Bell was at one end of the line, and Watson worked on the telephone in other room. The first transmitted words were, " Mr Watson, come here. I want to see you"
