What has changed in village life and town life from the 1900s till now?
Level: Intermediate
This is a huge question! For this you'll need to think about different aspects of village and town life and then research these online.
For example, you could look at changes in transport, types of work people do, communication and technology, types of food people eat, families, education, resources needed to keep a village/town/city running....
Also, you can look at Wikipedia, the online encyclopedia. You need to cross check this information with other sites though, as anyone can add to Wikipedia and the information is not always completely accurate. They have a good background article on the 20th century - with entries on each decade.
HOT TIP: for New Zealand information, try NZHistory.net - have a look at their article on Living in the 20th Century.
Another great New Zealand site is Te Ara, the online encyclopedia. You can browse through different categories to find the information you need, including pictures.
