1 . Winners of the Broadcom MASTERS
Girls took the top prizes at the Broadcom MASTERS, a science competition for middle school students.
Alaina Gassler
Alaina won the $25,000 Samueli Foundation Prize for the project of reducing blind spots in cars. She was inspired to solve this issue by her mother who didn’t like driving her vehicle because its large A-pillar (A柱) design made her feel in danger. “I started to think about how blind spots were a huge problem in all cars,” said Alaina. So she worked on and solved it.
Sidor Clare
Sidor won the $10,000 Marconi/Samueli Award for Innovation, an honor made by Samueli’s generous donation of his 2012 Marconi Society Prize Award. She developed bricks that could one day be made on Mars, so that humans wouldn’t be required to carry building materials with them in order to build there.
Alexis MacAvoy
Alexis won the $10,000 Robert Wood Johnson Foundation Award for Health Advancement, which recognized the student whose work and performance showed the most promise in health-related fields and demonstrated an understanding of the many social factors that affect health. She designed a water filter (过滤器) by using carbon to remove heavy metals from water.
Rachel Bergey
Rachel won the $10,000 Lemelson Award for Invention, awarded by The Lemelson Foundation to a young inventor creating promising solutions to real-world problems. She developed a trap made of tinfoil (锡纸) and netting for the spotted lanternfly, an invasive species causing damage to trees.

7 . The Chong Yang Festival has a history of over 2,000 years. It comes on the ninth day of the ninth lunar month, so it is called the Double Ninth Festival.
There are many kinds of activities on the Chong Yang Festival. It is a time when it’s getting cold, so Chinese people make the festival a time for sending winter clothes for the dead family members. Because autumn has a clear sky and fresh air, it is a very good time to climb a mountain. Climbing a mountain has been the tradition of the Chong Yang Festival since the Western Han Dynasty. Also, it is good for our health. On the Chong Yang Festival, people also eat Chong Yang cakes, enjoy chrysanthemum(菊花) flowers, and drink chrysanthemum wine.
Today, the Chong Yang Festival has got its new meaning —a day for showing respect to the old. On the festival day, people show their respect, care and love to old people, and they also do lots of things to help the old. Many parks, communities and organizations plan the activities for old people, such as an autumn trip, singing songs or sending presents to them. We hope the old are happy and stay healthy by taking part in these activities. Many young people accompany(陪伴) the old on outings, or make some delicious food for them.

9 . Have you tried to run or walk for exercise and then given up? If you answered yes, you should try a new kind of exercise: aquatic (水中的) exercise. Aquatic exercise is like exercise on land, but you do it in a swimming pool. More and more people are trying aquatic exercise now.
Aquatic exercise feels easier than exercising on land. Why? You weigh about 90% less in the pool. It is better for your knees than running or walking. Water is about 1,000 times thicker and heavier than air. To move through the water, your body has to work four times as hard. As a result, you can burn more calories (卡路里).
In fact, most people say they feel more relaxed in the water. They stop thinking about the things that make them worried. They feel in control of their bodies. The cool, quiet environment makes them feel good.
But what if you are afraid of the water? No problem! There is nothing to worry about. Aquatic exercise is safe and easy to learn. It doesn’t require any special skills. You don’t even need to know how to swim. Aquatic exercise is for everyone.
