How to Destroy Your Comfort Zone and Improve Your Life: A Science-Backed Guide"Growth and comfort do not coexist" — Ginni RomettyYou've definitely been told at various points in your life that you need to break out of your comfort zone.Maybe you've been at a restaurant and have been nervous to try a new dish, or you've been in the same position at the same job for too many years, and now it's time for a change. In any of these cases, it's probably time to break out in order to really succeed.Beyond discovering tasty exotic food, studies show that stepping out of your comfort zone leads to greatly increased productivity, creativity, and the ability to cope with unexpected changes and further your success.There's a big caveat (警告) though: When you're sweating bullets and are so terrified that you can barely function, stepping outside your comfort zone is anything but productive.Taking a leap of faith can be downrightintimidating. After all, our comfort zone has the word "comfort" in it for a reason. In fact, that's the reason many of us avoid stepping outside this zone – we've heard a million times over that it's great for us, but it feels absolutely awful in practice.Thankfully, science has an answer. A study conducted way back in 1908 by two psychologists showed that remaining in a state of comfort ensured steady performance (sounds about right). However, in order to increase or maximize performance levels, we need to be in a space of "optimal anxiety". This is where we benefit from a little bit of fear. Or, as theNew York Timesrecently put it, "If you're too comfortable, you're not productive. And if you're too uncomfortable, you're not productive. Like Goldilocks, we can't be too hot or too cold."Challenging yourself in this place can allow you to accomplish incredible things. Think of a mountain climber; when they begin climbing mountains they don't start with Everest. They start with smaller peaks until they build up a tolerance. Once that tolerance is reached, the climber will plateau (达到平衡) and achieve a steady state of performance, then destroy that tolerance until they reach the peak.You easily can do this too by reaching your "optimal anxiety" – that Goldilocks level where you achieve maximum productivity and continually push your boundaries.In Paragraph 3, why does the author give the example of trying out a new dish?A.To encourage people to balance the diet.B.To point out that people are very nervous at first trial.C.To suggest that people try different styles of life.D.To encourage people to step out of the comfort zone.2.People benefit from stepping out of the comfort zone in the following ways EXCEPT being more _____.A.creativeB.flexibleC.wealthyD.productive3.The underlined word "intimidating" in Paragraph 6 is closest in meaning to ______.A.frighteningB.indicatingC.encouragingD.interesting4.According to Paragraph 7, a space of "optimal anxiety" refers to where _____.A.you will be more productive by taking a few risksB.there is much more fear than you can takeC.you lack of self-confidence in doing somethingD.you feel extremely uncomfortable and scary5.According to the passage, what can people do to achieve "optimal anxiety"?A.To believe in the power of the fear.B.To make changes step by step.C.To be curious about everything.D.To learn new things every day.
