Public Speaking and Critical thinking
What is critical thinking? To a certain degree, it’s a matter of logic (逻辑)— of being able to spot weakness in other people’s arguments and to avoid them in your own.
In the broad sense, critical thinking is focused, organized thinking——the ability to see clearly the relationships among ideas.
If you are wondering what this has to do with your public speaking class, the answer is quite a lot. As the class goes on, for example, you will probably spend a good deal of time organizing your speeches.

【推荐1】Do you have a sleep problem? If you do, there is a simple way to help you improve your sleep. You may need to see more sunlight, especially in the morning, according to a study.
A team of researchers (研究人员) from New York, US did the study, reported Yahoo News.
The team did a study on 109 office workers across the US. They found that some of the workers saw lots of light during the morning hours, between 8 am and lunchtime. The researchers found that these workers had a better sleep than other workers. They also fell asleep more quickly at night.
Why is sunlight so important to our sleep? Researchers say it helps us set our “body clock”. When there is less and less sunlight at the end of the day, our body starts to make melatonin (褪黑素). It makes us feel sleepy so that we know it’s time to go to bed. Our body makes the most melatonin at night. But during the day, sunlight tells our body to make less melatonin so that we can stay awake (清醒的) and do our work.
Researchers suggest (建议) that we should see 15 minutes of sunlight in the morning. It can help balance (平衡) the melatonin in our bodies.

【推荐2】Every morning Hannah Griffiths and her workmates walked into the rainforest in the Maliau Basin in Bormeo, where they had set up a set of experiments to look at the ecological effects of small creatures: termites.
Termites get a bum rap in USA. They are thought to make the loss of billions of dollars each year because they bite up a huge number of woods. And they are responsible for something like 2 % of global carbon emissions, simply because of their huge populations and their like for biting through some special materials. People hate them and are trying to kill them.
But they play a key role in many natural ecosystems. Scientists have known for years that in tropical forests, termites eat up fallen leaves and dead wood. They help keep the fallen material under control. They let nutrients from the dead material back into the system to be used by other plants, insects, and animals. But scientists didn’t know exactly how important the insects were in keeping the forest healthy and functional, so they removed termites from a particular place in the forest and saw what would happen.
Hannah Griffiths and her workmates started their experiment. It chanced that the forest was hit by an extreme drought at that time. During the non-drought years, they saw there was wasn’t much difference between the normal places and the ones where they’d removed the termites. but during the drought, the effects were easy to see. What they found was unexpected: in the termite-rich areas, the soil stayed slightly wet, more trees sprouted, and the system was still full of activity during the long, dry period.
For Griffiths, she thought that they could pick out the real importance of termites to the system only because they accidentally studied termites during the drought. She pointed out, An “And that rings alarm bells in my head,” she said, “because it makes me think: what else don’t we know? If we start damaging biological com munities, what will happen? And what if a species dies out?”

Today, people want to do sports and exercise to keep healthy. But some of them have some wrong ideas about it.
“A plate of chicken is a good meal before games because it has much energy.”

No. Morning is a good time to exercise, but it may not be good for you. If an afternoon or an evening is better for you, and you enjoy the feeling of getting healthy, then you can exercise at that time. So choose any time to exercise!

You must have some water when you exercise. And after exercising, you also need to have some water. If you don’t drink any water, then you may feel tired.
