▶ Your Answer :
Both the reading and the lecture talks
about why people yawn. The reading suggest three possible reasons for it,
however, the lecturer disagrees with those reasons.
The
reading firstly mentions that people yawn for a way of communicating which can
show nervousness, boredom, or stress to other people. The lecture claims that
this is not acceptable because people often yawn when they are alone. If you
are alone, you do not have someone to communicate with, so you should not yawn
following to the reading passage. Also, people try to cover them yawning in
front of people at the office. If you are trying to express your condition, you
should not cover it.
The
reading claims that people yawn to equalize pressure of the ears with the
atmosphere. The lecturer disagrees with this statement because there are not
enough evidences. On top of that, if what the reading mentioned is truth, the
situations of yawning are extremely limited; however, people yawn all the times
in any situations.
Lastly, the reading says that people yawn to
increase alertness, especially from sleeping. The lecturer states that it is
not convincing, because people usually yawn before they fall asleep. Besides,
instead of waking up the brain by yawning like it mentioned in the reading
passage, it has a relaxing effect by moving facial muscles.
To
sum up, the reading mentions three possible reasons why people yawn, and the
lecture totally disagrees with those possibilities.
