by TRAN HUU GIANG - 1. Record a speech to share with your friends about the invention that you think is the best from the table below. The best invention needs to meet the four criteria listed in the voting sheet. Remember to include some reasons for your choice. The example may help.
2. After submitting your work, please listen to at least 3 of your friends’ recordings and write some comments (~20 words/comment).
Example: I vote for digital cameras because they are very useful. We use them to take pictures of people we spend time with or beautiful places we visit. What’s more, a digital camera does not cost too much, and we don’t have to buy rolls of film for it.
