[1]You may be wondering what scientists are like. The aim of this article is to explore the characteristics

that are common for scientists. You might even be considering becoming one yourself.

[2]So now let's get to the topic. What type of person should a scientist be? Don't lose heart if you don't

possess(拥有) all of these qualities, but having a few of them will be helpful.

[3]A scientist should be someone who enjoys research and studying. This makes up a large part of a

scientist's work. Carrying out studies that will improve people's everyday life is an exciting challenge.

Moreover, making the next scientific discovery is highly rewarding but it takes a lot of work and

preparation.

[4]If you come into contact with a scientist, one of the things you might notice is that they have an open

mind. They are flexible and open to new possibilities and there is a very good chance that they might live

their life in this way.

[5]Perseverance(毅力) is also a quality that is required for a scientist. Experiments don't always go to

plan. Each experiment needs to be adapted slightly to try and encourage more favourable outcomes. A

scientist cannot give up at the first difficulty.

[6]          , most scientists seem to show curiosity. They seek answers to many mind-puzzling life

questions. Their job is usually to ask how, what and why things happen and to provide theories that

demonstrate this.
