文章大意:本文主要介绍了“大喊”的好处。

【推荐2】We have to accept the truth: Sometimes, we just want to shout out loud.

For example, we all have days like this: our dog has made a mess on the floor we just cleaned, or our friend called to tell us he or she couldn’t come at the last minute when we had cooked dinner for him or her. We might be really angry but we tried to tolerate things like those. According to ancient Chinese wisdom (至理名言), we should shout in a loud voice instead of keeping quiet. In fact, it’s good for our health.

“Chinese people have passed on the practice from ancient times to now as a part of traditional medicine.” said Mrs. Li, a 60-year-old woman from Hangzhou. “My parents taught me to do this. It’s a part of our folk (民俗的) culture.”

Mrs. Li is a member of a group of people who love shouting. Each morning, she and some of her friends climb to the top of a hill and let out loud shouts before starting their daily exercise. They believe that shouting is good exercise for their lungs (肺) and it brings them a lot of fun.

“Sometimes I shout out and others shout back,” said Mrs. Gu, another shouting lover. “It makes you happy. You laugh and then you feel very comfortable.”

Dr. Peter Calafiura, an American doctor, agrees that shouting can have a positive influence on people’s health.

So, next time you start your morning run, why not try to shout out first? It will make you healthier.

1. The underlined word “tolerate” in Paragraph 2 means “________” in Chinese.
A.纠正B.忍受C.铭记D.批判
2. Mrs. Li learned to shout to make herself feel better from ________.
A.her parentsB.her teacherC.Mrs. GuD.Dr. Peter Calafiura
3. Where does Mrs. Li shout every day?
A.In a park.B.At a square.C.In her house.D.On a hill.
4. What does Dr. Peter Calafiura think of shouting?
A.It’s great fun for people.B.It’s good for people’s health.
C.It’s easy for people to learn.D.It causes problems on people’s health.

【推荐3】In our solar system (太阳系), there is only one planet that is full of lives. It is our Mother Earth.

Just like mothers look after everything in homes, Mother Earth looks after everything around the world. Do you know when Mother Earth’s birthday is? It is April 22. People call the day the Earth Day. People around the world celebrate this day by making it very special for her. How do you think she will feel special? She will feel special if all of us love nature, keep it clean and use all of her seas, mountains and other natural resources (资源) in a right way.
