　　(2017·太原市部分重点中学联考)

　　Mental and health experts believe personality plays an important part in how we experience stress. Personality is the way a person acts, feels and thinks.

　　Some people are aggressive and always in a hurry. They often become angry when things do not happen the way they planned. They belong to “Type A” personality. Studies suggest that these people often get stress­related disorders. The “Type B” personality is calmer. These people are able to deal with all kinds of situations more easily. As a result, they are less affected by stress.

　　Studies have also shown that men and women deal with stress differently. Women seem to be better able to deal with stress than men are.However, experts say women are three times more likely to develop depression in reaction to the stress in their lives. American writer John Gray became famous for his book，“Men are from Mars, Women are from Venus”．He notes that men and women have opposite ways of dealing with stress. For a man，the best way is to rest and forget about daily problems.
