One-off chopsticks are very popular, but now using them has some problems.
Some people think we shouldn¡¯t use them any more. On one hand, we need to use a lot of wood to make them. On the other hand, they pollute environment after we use them. What¡¯s worse, many one-off chopsticks are not clean enough for people to use. They are bad for our health.
But others think we should keep using them. Because it is very convenient to use them. Then, it is much cleaner and healthier to use them than the traditional chopsticks. And it is helpful to save some water because we don¡¯t need to wash them after using.
In my opinion, I think we should use fewer one-off chopsticks so that we can save more trees. And we should also use clean chopsticks to keep healthy.

¡¾ÌâÄ¿¡¿ More than its influence on health, not getting enough sleep can lead to car accidents or other mistakes. Here are what sleep researchers have found about how to sleep.
How much sleep do we actually need?
It is known that all of us naturally need no less than 8 hours of sleep per night. When we sleep below six hours per 24, we¡¯re at an increased risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Suddenly there is no storage system for sleep in the brain.
Can we train ourselves to need less sleep?
As a study in 1964, a 17- year- old boy named Randy Gardener stayed awake for 264 hours. How many people could do anything close to that without dying?
When you are reading this, you might say you usually get 6 hours of sleep and feel just fine . Sleep experts often compare people without enough sleep to drunk drivers: They don't get behind the wheel thinking .They are probably going to kill someone.
Can we drink coffee instead of sleeping?
Coffee can keep us awake. Remember, too much coffee may throw off our sleep and energy cycles. So avoid caffeine for 4 to 6 hours before bedtime.
Does a sense of purpose connect with sleep quality?
A new research suggests a kind of strong connection between purpose in life and sleep. People who have a great sense of purpose usually have better physical and mental health, which in turn explains their higher quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.
