During the early 20th century, the construction of tall buildings became very popular in big cities. Cities grew bigger as many people could live and work there. Tall buildings were also seen as a symbol of power and greatness. Major cities, especially in America, fought for the tallest buildings in the world. For four decades the Empire State Building in New York was the world's highest structure. The 381-metre high landmark has 102 stories and was completed in 1932. The World Trade Centre, finished in 1973, became a symbol of the city's economic strength. The destruction of the World Trade Centre in the terrorist attacks of 2001 hit the heart of the city. Today the world's tallest buildings no longer stand in America. Other countries, mainly in the growing regions of Asia, have entered the prestigious race for the tallest structures in the world. Some experts say building a 1000-metre high structure would be no problem with today's technology; others think that we need lighter, stronger materials as well as faster elevators to make this possible.
1. Did the film win any Oscars at the ceremony last year? (The film won)
To answer this question, we need to determine if the film won any Oscars last year. To do this, we would need to check the information about the Oscars ceremony that took place last year. We can use the Past Simple form of the verb because the action of winning the Oscars is a specific event that happened at a definite point in the past.
2. Have you ever read a play by Shakespeare? (I have never borrowed)
To answer this question, we need to think about whether we have ever read a play written by Shakespeare. If we have not borrowed a book from the library, then it is unlikely that we have read a play by Shakespeare. We can use the Present Perfect form of the verb "borrow" because it is an action that started in the past (We have never borrowed) and could potentially continue up until now (We have never borrowed a book from the library).
3. Did you know that Peter wrote a novel in 2012? (I didn't know)
To answer this question, we need to consider whether we were aware of the fact that Peter wrote a novel in 2012. If we were not aware of this information, we can respond by saying "I didn't know." We can use the Past Simple form of the verb "know" because it is a one-time event that happened in the past.
4. Megan and Sam did not see the Twilight films, but Kim has. (Megan and Sam have not seen)
To answer this question, we need to determine if Megan and Sam watched the Twilight films. If they did not watch the films, we can say "Megan and Sam have not seen." However, Kim has watched them. We can use the Present Perfect form of the verb "see" because it is an action that started in the past (Megan and Sam have not seen) and has a connection to the present (Kim has seen).
Overall, it is important to remember that the Past Simple form of the verb is used for specific events that happened at a definite point in the past, while the Present Perfect form of the verb is used for actions or experiences that started in the past and have a connection to the present.
