1. (2020·温州模拟) 阅读下面四篇材料，然后从各题所给的四个选项中选出一个最佳答案。

     Shyness can be an unhappy feeling. But the good news is, you're not alone.

     Scientists say that more than 40 percent of teenagers and adults consider themselves shy. Shyness is feeling a little nervous or as if you want to hide when you're around other people or in a new situation.

     ______ Scientists say such things as genetics(遗传基因),life experiences, and environment can influence whether a person is shy. For example, in some families, everybody seems to be shy.

     What happens if you are shy? Well, being shy may cause you to avoid or miss opportunities you would enjoy.

     How do people overcome (克服)shyness? This is what Gilbert tells us. "When I started off trying to get over being shy, I decided to do little steps at a time, including practicing smiling and saying hi to people. And it worked for me."

     But shyness is not the kind of thing that most people can get over overnight.

     Overcoming shyness take time and needs practice.

     Here are some tips given by scientists.

     Think of what to talk about before you leave home. Prepare things to talk about before you're in a social situation. For example, if you know your classmates are interested in an upcoming event, learn about it so you can join in the conversations.

     Let people know you're shy. If you're shy, just show it. Instead of letting people guess, tell them the truth. Explain that you are shy and feel nervous but enjoy talking to people.

     Make things easy for the other person. Remember, you're not the only shy person  around. Do what you think might help others feel good-for example, say hello or smile.

     Pick one social skill to practice at a time. Start simply. For example, smile or be the first person to say hi. Choose skills you feel comfortable enough with to practice.
