Unit 6 When was it invented?
Section B (3a-Self Check)
Sample
This special pen was invented by Liu Jie. It has
板书设计
three colors and is used for taking notes quickly. It is
very useful if you have a lot to write down. The pen
comes with a microchip that can store a list of
common words that you will use. You can program the
words you will use often into the microchip’s memory,
then assign a short form to each word. When you are
writing, you just need to write the short forms with the
pen, press a button on the pen and the short forms
will change into the actual words. The microchip can
contain up to 50 words and you can make changes to
the list of words whenever you need to.
