Notes

Key point 3: yawning is a good behavior. to cool blood flowing in the brain

Lecture:

Main idea: reasons for yawning challenged

Key point 1: according to the reading, the theory should be that while the blood is not lacking oxygen, people will not yawn any more. however the truth is opposite.

Key point 2: there are a lot of behaviors when babies are in their mothers’ stomachs. However other behaviors disappeared when babies grow up.

Key point 3: according to the passage, while people are living in cold conditions, they will not yawn. But the truth is that no matter people are living in a hot or cold environment, people still yawn.

Sample writing

Both the reading passage and the lecture focus on yawning. The reading passage puts forward three possible reasons for yawning while the lecturer holds the opposite view, challenging the arguments in the reading passage.

 

The first point mentioned by the author is that yawning could probably increase the level of oxygen in blood. The lack of oxygen will result in yawning. However, the lecturer refutes this by saying that according to the author’s opinion, people would not yawn any more when their oxygen level was balanced. He also gives an example that in real life people who take in pure oxygen still yawn.

 

Second, the reading passage states that yawning may be the unborn-babies’ reflex behaviors by which they could get rid of a certain kind of liquid in their lungs. The lecturer casts doubt on this idea. He argues that reflex behaviors would gradually disappear as babies grow up. But adults still yawn.  

 

Third, the reading passage points out that yawning could cool blood flowing into the brain. However, in the listening passage, the speaker disagrees with this idea by saying that if the author’s view is true, then people in tropic areas are prone to yawn more often. But there is no convincing evidence to show the connection between yawning and weather. 

 

To sum up, the author of the reading passage indicates three possible reasons why people yawn. The lecturer, on the other hand, believes all of these are not convincing enough.

Supplementary readings

Why do we yawn?

Almost everyone yawns when they feel sleepy. So do most animals. But we don't completely understand why people and animals for that matter, yawn.

It's widely assumed that yawning occurs because we are tired or bored or because we see someone else doing it, but there isn't any hard evidence to support these beliefs.

Scientists do not purport to know all of the biological mechanisms of the yawn, but tend to agree that a yawn is an involuntary respiratory reflex, which regulates the carbon dioxide and oxygen levels in the blood.

Technically, a yawn is the reflex opening of the mouth followed by the deep inhalation and slow exhalation of oxygen.

The very act of yawning is but one of a number of involuntary reflexes controlled by the spinal and nerve centers.

Scientists speculate that the onset of a yawn is triggered either by fatigue, or by sheer boredom as, at those times, breathing is shallow, and little oxygen is carried to the lungs by the oxygen-toting cardiovascular system.

When one yawns, his or her alertness is heightened, as the sudden intake of oxygen increases the heart rate, rids the lungs and the bloodstream of the carbon dioxide buildup, and forces oxygen through blood vessels in the brain, while restoring normal breathing and ventilating the lungs.

This quite plausible theory of yawning falls short of explaining many aspects of yawning. Scientists explain away the "contagious" nature of yawning, that is when one person's yawn triggers another nearby to yawn, as due to the power of suggestion, but are at a loss when attempting to explain why yawning occurs excessively in patients with lower brainstem damage or with multiple sclerosis.

Other unlocked mysteries include why fetuses in the womb yawn, when it is a well-known fact that they do not intake oxygen into their lungs until after live birth, or why individuals with high concentrations of oxygen in their blood streams yawn.

Until these questions are answered, do not assume that a person who yawns in your presence is bored with what you are saying, or suffers from exhaustion. Simply be pleased that he or she is not bored to death.

Sample writing on a similar topic

The statement in the direction is a long-term consideraion of many people including me. Many people will argue that playing a game is only fun when you win. I, however, after thinking about it on many occasions, decide to stand up against this view for the following reasons.

 

The first and the most important reason for my opposing the idea is that playing a game, no matter you win or lose, helps release a person from the heavy pressure, in most cases, resulted from intellectual activities. There is no better example than myself when I was trying so hard to enter the university. At that time, when I was too exhausted to memorize any single incident in the history book, a play of badminton would refill me with fresh energy to go back to my studies, though I hardly won any of these badminton games as my partner is an excellent player. Therefore, the biggest advantage of playing games lies in the fact that it helps people relaxed.

 

Another reason for my disagreement is that one will find out his or her capacity of making progress while playing a game. When learning a new gameyou're your opponent is a more mature player than you are, it is for sure that you will not win him or her at the beginning, but in the process of the game, if you are a conscientious player, you will definitely learn to grasp the basic skills of a certain game, which enable you to play better and better. Consequently, the awareness of your ability in learning new things is the best award you can find in game playing.

 

Therefore, I will conclude by saying that playing a game itself is worthwhile and to win or not to win is not a matter to concern since you could get rid of the feeling of exhaustion and confirm your confidence as a learning-capable being.
