Waves of immigrations - Reasons for immigrating

Hey guys,

today you had to listen to the recording once more and concentrate on the ethnic groups and where they mostly lived.

Then you had to give a definition for the words "melting-pot" and "diversity" from what you understood from the document. Here is what you said:

New York is a fantastic melting-pot:

The city is compared to a melting-pot because there are people from many different countries in one place. It's an emblem for diversity because of the successive waves of immigration that came to "New World" = the USA

Finally, you had to imagine some possible reasons why people wanted to immigrate to the US and identify the facts actually mentionned in the interview:

Reasons for immigrating: (Why ?)
.. because they were attracted to the USA.
.. because they were enslaved
.. because their countries were destroyed (cf. WW II = World War II)

Purpose / Goal / Aim: (What... For ? )
... to work
... to have a new life
... to build a new life
... to leave their misery
... to live the "American Dream"
