For each working person, the rarest resource is your daily time. You may feel like that you do not have enough hours in the day, only endless things to do. Of course, some of these things are not part of your job, such as other colleagues asking for your help or bosses making new demands.
How can we reasonably refuse them?
1. Just by doing the following three steps, you can usually make yourself and the other person comfortable while refusing them.
◆ Listen patiently to others’ requests
It’s not simply hearing what the other person is saying. You have to stop what you’re doing and carefully listen to what they say. 2. The point is to let the other person see that you are willing to help, and let them understand that you’ve already known their needs. In this way, even if you eventually refuse them, they’ll understand that you are not available, instead of not willing to help.
◆ 3.
When we listen, we all hope that other people will come to a conclusion quickly. But when we speak, we instinctively（本能地）start from the beginning of the story. In fact, this way of speaking is not good for communication. So if you want to refuse somebody, just tell them No, and then explain the reasons why.
◆ Provide an alternative solution
Maybe you really don’t have the time to listen to the other person’s request. In situations like this, don’t just tell the other person that you don’t have the time. 4. For example, you may say, “Sorry, I really don’t have the time right now. Is it OK if we talk tomorrow morning?” In this way, although you refuse him, he still can feel your support.
In conclusion, refusal is unavoidable, but you can choose the way to refuse. An inappropriate refusal may cause great harm to your working life.5..
A. Begin with conclusion when refusing.
B. Start from the beginning when refusing.
C. Even if your time is limited, it is best for you to do so.
D. Instead, you should give them a time when you would be available.
E. In addition, this willing-to-help attitude also shows leadership skills.
F. In fact, there has been a mature methodology (科学方法) for this matter since long ago.
G. An artistic refusal, on the other hand, may lead you to some unexpected benefits.
It happens from time to time: you feel terrible when you take your first bite of a certain food, but after eating more, you find yourself enjoying it. This is what is called an acquired taste. But why do our tastes change?
The answer, according to a recent study presented at an American Chemical Society meeting in Boston, lies in proteins in our saliva (唾液).
Most of us tend to think saliva, almost entirely made up of water, is “only a mouth lubricant (润滑剂) helping us to swallow food,” the New York Times said. However, it also contains many proteins, which can help break food down, protect our teeth and help in tasting food.
To explain how these proteins affect taste, a team of scientists from Purdue University in the US invited 64 volunteers to drink a bitter-tasting chocolate milk three times a day for six weeks and rated their tastes at the same time.
According to the research, the participants found a strong bitterness on the first day, but the unpleasant flavor came to decrease as time went on and finally disappeared.
That is not all that was changing. A noticeable increase in the levels of proline-rich (富含脯氨酸的) proteins was found in the saliva samples of the test subjects in the research period. These proteins serve to reduce the bitterness we taste and improve our adaptation to this flavor.
“We think the body adapts to reduce the negative feeling of these bitter compounds,” said Cordelia Running, a food scientist at Purdue University. “Saliva changes flavor, which in turn changes eating choices.”
This change in taste not only makes the food tastier, but also helps people keep an appetite for healthy food whose flavor might otherwise keep them away.
One day, these proteins may even be extracted (提炼) and used as a separate food additive that could help people stick to healthy food whose flavor they continue to dislike, researchers told Science Alert. And according to Running, even it doesn’t happen, the idea that “maybe some little piece of your body is actually trying to help you” could really benefit some people. Let’s wait and see.
