Unit 1 Nanotechnology
Listening Comprehension
Many things in our world are getting smaller. Computers and cell phones are good
examples. Both are getting smaller each year. But now some things are getting really
tiny. Scientists can now make new machines with nanotechnology. Because nano
machines are so small, you can‟t see them.
Right now, scientists can only make very simple machines with nanotechnology. In
the future, they will probably make more useful machines. Scientists hope they can
make tiny robots with nanotechnology. These tiny robots could work inside our bodies.
They could fix problems in our bodies without surgery. Also, nano robots will probably
do many of our dangerous and unpleasant jobs.
