Learning objectives
Warming up
In our free time we can sculpt a sculpture and paint a
painting, but we take a photo. While we're doing this
traveling, we can get seasick at sea, airsick in the air and
carsick in a car, but we don't get homesick when we get
back home.

And “softly” not an opposing pair If harmless actions are
the opposite of harmful actions, why are shameless and
shameful behaviors the same
Warming up
Even the smallest words can be confusing.
When you see the capitalized "WHO" in a
medical report, do you read it as the "who"
in “Who's that ” What about “IT” and “US”
The stem(词根) and its value
are the basis of the English language.
