Philadelphia offers a ton of attractions that are suitable for people of every age and here are some family-friendly attractions.
Spruce Street Harbor Park
Spruce Street Harbor Park, one of the best urban beaches in America, is an outdoor heaven on the Delaware River waterfront. Visitors can relax in a hammock, play on the playgrounds, and play games like table tennis and giant chess. Don't miss out on the park at night, when colorful LED lights hanging from treetops make the entire area bright.
Blue Cross River Rink
Offering ice skating in the winter and roller skating in the summer, Blue Cross River Rink creates a fun, outdoor experience for the whole family. Visitors can play on the nine-hole mini-golf course during the summer, and enjoy eats and drinks from the onsite(现场的)bar and restaurant all year round.
Sesame Place
Big Bird, Elmo and the other stars of Sesame Street come out and play at Sesame Place, the only theme park in the nation starring the popular TV show's most lovable characters. A water park, interactive activities, parades, fireworks and shows add to the fun.
Once Upon a Nation Storytelling Benches
On summer days, uniformed and professional storytellers at 13 storytelling benches throughout Philadelphia's Historic District entertain visitors with true, free, three-to-five minute tales about the colonial(殖民的)era as part of Once Upon a Nation. Children can pick up a Story Flag at any storytelling bench, and then collect a star from every storyteller on their journeys. Flags with all the stars can get free rides on the Parx Liberty Carousel at Franklin Square.
It was a rainy day. I had no desire to drive up the winding mountain road to my daughter Carolyn's house. But she had insisted that l come to see something at the top of the mountain.
So here I was, although unwilling to make the two-hour journey through fog and rain. After lunch, my daughter requested me to drive her to Barrage. After a ten-minute drive, we parked the car and got out. We walked along a path that was thick with old pine needles. Huge black green evergreens towered over us. Gradually the peace and silence of the place began to fill my mind. Then we turned a corner and stopped--and I gasped in amazement.
From the top of the mountain to the slopes and valleys, were rivers of daffodils(水仙) in full bloom. A sea of amazing colors, like a carpet before us. It looked as though the sun had tipped over and spilled gold down the mountainside. At the center hung a waterfall of purple hyacinths. Here and there were breathtaking tulips.
A riot of questions filled my mind. Who created such beauty? Why? How?
As we approached the home. We saw a sign that read" Answers to the Questions IK now You Are Asking." The first answer was:" One Woman--Two Hands, Two Feet, and Very Little Brain. "The second was: "One at a Time." The third: "Started in 1958."
I was so moved by what we had seen. "She changed the world," I said, not getting over the shock. "One bulb(球茎) at the time. She started almost 40 years ago, probably just the beginning of an idea, but she kept at it."
"Imagine," I added," if I had a vision and worked at it, just a little hit every day, what might have accomplished?""
Carolyn looked sideways at me, smiling. "Start tomorrow," she said, "Better yet, start today."
Every year, hundreds of millions of Monarch Butterflies (黑脉金斑蝶) from Canada and the United States journey as far as 2,500 miles to the forests of Michoacan, Mexico, a place which has the world's largest insect migration. It's such a breathtaking sight, but as always, human greed is threatening to destroy it.
The Monarch Butterflies start to arrive in Michoacan in late October to make their winter home in the trees high up in the mountains of the natural reserve. Once there, they gather together in large masses. These masses often become so heavy that they cause tree branches to bend or even break. But there's a purpose of all these massing - it allows the butterflies to survive in the low nighttime temperatures at these high altitudes.
The Michoacan Monarch Butterfly Sanctuary(保护区) is most impressive during the months of February and March, just before the winged insects begin their long journey home.
Mexico's Butterfly Forest is a shelter protected by law, and one of the country's most popular sights, but that hasn't stopped people from slowly but steadily destroying it.
Illegal woodcutting in the heart of the Monarch Butterfly Biosphere Reserve has been a longstanding problem, but criminals are rarely brought to justice. They are oftenest free after paying some money.
Just last month, an even greater threat rose in Michoacan's butterfly home. The country's largest mining corporation gained the right to reopen an old mine in the heart of the monarch reserve. Experts believe that if the mine is reopened, it will likely spell the end of this magical place.
And as if all this wasn't bad enough, the increasing use of herbicides (除草剂) in the American corn belt has led to the decrease of a plant which is essential to the monarchs' development from egg into butterfly.
In the near future, IoT (Internet of Things) will drive huge innovation (革新) in the way our food is grown. Plants will have a "voice", not a human voice, but a voice based on data that can tell people, computers, and machines when, for example, they are thirsty, or need more sun, medicine, etc.
Take vertical (垂直的) farms, for example. Farming is moving indoors where the growth of plants can be monitored and controlled. The facilities are built vertically, so growing areas can be put in piles. This greatly reduces the amount of land needed for farming.
From an loT point of view, vertical farms are connected in two ways. First, small sensors (传感器) in the soil or connected to plants tell a control system exactly how much light, water, and nutrients are needed to grow the healthiest crops. Sensors will also tell vertical farmers when crops are nearing their peak for harvesting at just the right time to make sure it's still fresh when it reaches its final destination.
Second, vertical farms will be connected to other networks and information systems, including databases that track local demand. For example, local restaurants may input when they need fresh food supplies. And vertical farmers could get that information so they know which crops to grow in what quantities. This type of loT system would have been unimaginable a generation ago.
Today, vertical farms are being experimented. Yet, the numbers point to a bright future for the industry, especially as the world's population continues to grow. For example, Green Sense Farms in Chicago is able to harvest crops 26 times a year using85 percent less energy, one-tenth the water, and no pesticides. A side benefits of lower energy use is lower CO2 output of two tons per month, with the added benefit of creating 46 pounds of oxygen every day.
Ways to be safe in school
School safety issues involve more than violence. It may also address such concern as natural disasters, illness, fire and local emergencies.
Have a plan
Teachers and students should know where to go and what to do in case of a school security situation. . Schools can also post guidelines in each classroom with simple pictures pointing out emergency exits, fire extinguishers(灭火器),and other emergency equipment.
Screen visitors
. Give school visitors temporary badges(证章) to identify them. Insta1lcameras at all entrances and restrict access as much as possible. Ask teachers and hall monitors to stop anyone in the halls without appropriate identification.
Panic buttons
Provide teachers with panic button in classroom so they can ask for help immediately. Provide clear and brief instructions about use and immediate response when started.
Establish a hotline
Establish a hotline so students can report crimes and threats anonymously(匿名地). Post the number in obvious locations so students can see it on a regular basis. . Establish a student disciplinary committee, and develop peer counseling programs for newcomers and victims of bullying(欺负).
A. Teachers and students should be certain that immediate help will arrive.
B. Visitors are not allowed to enter schools.
C. Students may report crimes and threats more quickly without being identified.
D. Require that all visitors enter the security office and explain why they are there.
E. It is said that about 16,000 students die in school accidents every year in China.
F. So what can we do to make the school a safer place?
G. Just as schools practice fire drills, they can conduct safety drills.
All of us in Monte Vista Christian School know we'll one day have graduation photos for the yearbook taken. As the time1, the girls start to have a2about what they'll wear and where to take the photos, while the boys,3, hardly talk about it. As for me, I4for my photos to be taken by the sea.
When I arrived there, l met my photographer, Annie. She asked me to make some poses and I5her advice. After that, I asked if she could make me look6by taking a photo in a different way,7I'm less than 1.6 meters tall. To my8she responded," I will make no9to make you look like someone you're not.

A second crew of three astronauts are heading for China's Tianhe space station module after the (succeed) launch of the Shenzhou – 13 mission Friday. Astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu will be busy during their six months in orbit. They'll spend a lot of time (test) and validating(验证) technologies that will allow China to finish construction of the new space station, is called Tiangong ("Heavenly Palace"). That station will consist of three modules; the other two (expect) to launch toward the 54-foot-long (16.6meters) Tianhe next year. For example, the Shenzhou 13 crew will move the robotic Tianzhou 2 cargo(货物) spacecraft from one Tianhe docking(对接) port to using the module's robotic arm, Chinese officials said. Tianzhou 2 (arrive) at Tianhe in May, delivering supplies for the Shenzhou 12crew. Zhai, Wang and Ye will also conduct a variety of (experiment) onboard Tianhe, including work (design) to advance space medicine and scientists' understanding of microgravity physics. And researchers on the ground will keep close tabs(监视) on the trio's health, to learn more how long-duration spaceflight affects people (mental) and physically. The crew will also conduct two or three spacewalks during the Shenzhou 13 mission.

When I was a child, I was interesting in everything about the universe. One day I spot a picture of Armstrong, which was the first astronaut to set foot on the moon. Inspired by his story, I made up his mind to become an astronaut but dreamed of going into outer space. After know my dream, my father kept on encouraging me to follow by my heart. Besides, he advised me take exercise for 60 to 90 minute a day to keep fit. With the encouragement and support of my father, I was confidence that my dream would come true.
