This afternoon，we’re going to talk about the unique characteristics of glass and recent innovations in glass technology.Glass does not release any dangerous chemicals and bacteria cannot pass through it，which makes it suitable for storing food，drinks，and medicine.Glass can also be cleaned easily，reused many times，and recycled repeatedly，making it friendly to the environment.A surprising characteristic of glass is that it doesn’t break down in nature.This is why we can still see many examples of ancient glass work at museums.
Glass−making began in Mesopotamia roughly 4，500 years ago.Beads and bottles were some of the first glass items made by hand.As glass−making became more common，different ways of shaping glass developed.One ancient technique uses a long metal tube to blow air into hot glass.This technique allows the glassblower to form round shapes which are used for drinking glasses or flower vases.Spreading hot glass onto a sheet of hot metal is the technique used to produce large flat pieces of window glass.
Today，new technology allows glass to be used in exciting ways.3D printers that can make lenses for eyeglasses have been developed.Smart glass can be used to adjust the amount of light that passes through airplane windows.Other types of glass can help control sound levels in recording studios or homes.Moreover，tiny pieces of glass in road paint reflect light，making it easier to see the road at night.
Due to these characteristics，glass can be found everywhere we go.Our first group investigated the use of glass in some European countries.Group 1，go ahead.
