For the entirety of our life we have been coping with anxiety. But having some anxiety, especially in a stressful situation, isn’t     1     bad and can actually be beneficial, experts say. The right amount of anxiety can improve performance.

Anxiety is an uncomfortable emotion, often     2     by uncertainty. It can create intense, excessive and     3     worry and fear, not just about stressful events but also about everyday situations. There are usually physical symptoms too, like fast heart rate, muscle tension, rapid breathing, sweating and     4    .

Too much anxiety can be debilitating (使体弱力衰). But a normal amount is     5     to help keep us safe, experts say. “The emotion of anxiety and the underlying physiological stress response evolved to protect us,” Wendy Suzuki, a neuroscientist and the author of “Good Anxiety,” said, “Managing stress may be more useful than getting rid of it.” According to the Yerkes-Dodson Law, a theory that originated in the early 20th century from experiments on mice, increasing amounts of cognitive arousal, or stress, can improve performance — but only up to a certain point. The theory, represented by a curve shaped like a mountain, shows that after it peaks, greater levels of stress cause performance to     6    .

When anxiety is turned up too high, Dr. Suzuki added, it tends to become less useful. The first step in controlling anxiety that holds you back is to     7     when you’re feeling overly anxious and try to dial it down.

A certain degree of anxiety can help people prepare for a potential     8    , remain cautious and stay organized. But if anxiety is making you “uncomfortable more often than not” or interfering with     9     functioning and preventing you from living the life you want to live, that signals the need for additional support,     10     from a mental health professional.

Happiness, according to the Oxford English dictionary, is based on luck or good fortune. Joy on the other hand, is described as a vivid emotion of pleasure. Thus, happiness depends on     1    ; joy, on our emotional well-being.

If you know joyful people, you will probably notice common traits among them. Joyful people are often healthy, both     2     and mentally; they value strong     3     relationships, and they don’t allow the extremes of life -- sudden highs or sudden lows -- to     4     them too much. Joyful people lead a more stable life. But these abilities do not just arrive; they have to be worked at.

Teaching ourselves to be joyful may be one of the greatest things we can do to enhance our     5     health. However, it is important to understand that joy is an emotion that arises from within us and is not     6     by the things that happen to us. Instead of looking for external things to provide happiness in our lives, we must     7     to find the joy within. We must educate ourselves about joy and work to enhance it in our lives. One way to start is to make a     8     to wake up every morning and find joy in our lives. Think about a special person or a     9     pet. It is our choice to be joyful or fearful. Let’s take the time to train ourselves to be    10     -- our lives will be both happier and healthier for it.
