1 . A new device works like a solar panel, except that it doesn't harvest energy from the sun. It absorbs energy from the cold night sky.
A prototype(原型）of the device produced enough electricity at nigh to power a small light bulb. A bigger version might one day light rooms or charge phones. It also could power electronics in remote or low-resource areas that lack electricity.
The device makes use of the temperature difference between Earth and outer apace. It then uses that difference to create electricity. As long as one side of it is cooler than the other, the generator can produce electricity. The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent cover and surrounded with insulation(隔热材料）to keep out heat. The bottom of the generator is attached to an exposed aluminum plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.
Researcher tested a 20-centimeler prototype one clear December night in Stanford, California. The generator produced up to about 25 milliwatts of power per square meter of device. That was enough power to light small light-emitting diode, or LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. To do that, the system might need more insulation around the cool top plate.
The device also could help power remote weather stations or other environmental devices, says Aaswath Raman. He is a materials scientist who worked on the device at the University of Califomia, Los Angeles. This may be useful in polar regions that don’t see sunlight for months at a time, Raman says. “If you have some low-power load and you need to power it through three months of darkness, this might be a way.”

2 . Good Schools to Learn English
Atlanta English Institute (AEI)
It is designed for academically oriented, non-native speaking adults from beginners levels to those seeking mastery. Each program in the school is specially designed for our students and based on their current English levels and their goals. a student may register anytime, not merely at the beginning of a course. But at the middle of the course, registration time depends on the availability of space in the classrooms.
Atlanta International Language Institute (AILI)
It provides the opportunity to learn how to read, write and speak English as a second language for those who have little knowledge of the English language. Courses include ten continuous weekly classes and the classes meet once a week for two hours. The curriculum of this language program is built for groups of three or more students who can complete the material in ten weeks.
TALK Atlanta English School (TAES)
Located in the heart of Atlanta's Midtown Center area on Peachtree Street, it opened in 2011.

Language Institute of Georgia (LIG)
It is a well-established school in Atlanta that offers English classes using Graded Reader Method. Our maximum class size is eight students. Class meets once a week for two hours for six weeks. Please check our schedule section for start dates. Refunds (退款) have to be requested within a week of the start date of the class.

3 . Around this time of year when the weather gets cooler in Arkansas, there are a lot of homeless people, as well as people with different situations who just need help.
Oftentimes Our family serves at a soup kitchen where they give out bags of food to needy families in our area. And we’ll help put those bags of food together and hand them out, among other things.
There are a lot of reasons why serving the community is important to me, but one of them has to do with my father. My grandfather died when my father was 4 years old and my grandmother had four kids all under the age of 5, all born pretty close together. That was a time when things were so bad in the country. There wasn’t work and often the family hardly made ends meet, so my grandmother put the kids in a childrenˈs home so that they could at least have food to survive.
My dad said he never forgot the local charity would bring the kids a gift for Christmas. The kids worked hard in the children’s home and the only present they got was from the local charity. He never forgot this kindness and always appreciated the local charity for what it did when he Was a little boy.
My dad was such a hardworking worker- family meant the world to him. I was the seventh baby in my family and my mother had me just after she turned 40. She was one of those high-risk pregnancy moms, and Iˈm so grateful she had me. My mom and dad made a happy home for us, and I’m so grateful for that. I hope my children are catching those lessons, not just from Mom and Dad, but from grandparents and everyone else in their lives.
