1 . While screen time is known to affect sleep, new research suggests that interactive (互动的) activities, such as texting friends or playing video games, put off and reduce the time spent asleep to a greater degree than passive (被动的) screen time like watching television, especially for teens.
The team studied the daytime screen-based activities of 475 teenagers using daily surveys. They asked the teens how many hours they had spent that day communicating with friends through social media and how many hours they spent playing video games, surfing the internet and watching television or videos. Finally, the researchers asked if they had joined in any of these activities in the hour before bed.
Next, the team measured their sleep time for one week. The researchers found that the teens spent an average of two hours per day communicating with friends via social media, about 1.3 hours playing video games, less than an hour surfing the internet and about 1.7 hours watching television or videos. For every hour throughout the day that they used screens to communicate with friends, they fell asleep about 11 minutes later averagely. For every hour to play video games, they fell asleep about 9 minutes later. Those who talked, texted or played games in the hour before bed lost the most sleep: about 30 minutes later.
Interestingly, David, lead author of the study, said the team found no obvious relations between passive screen-based activities and sleep. “It could be that passive activities are less mentally exciting than interactive activities,” said Anne, co-author of the study. “It’s a tricky situation,” she said. “These screen tools are really important to everyone nowadays, so it’s hard to put a limit on them, but if you’re really looking out for a teenager’s health and well-being, you might consider limiting the more interactive activities, especially in the hour before bed.”

3 . As newer, more advanced technologies come out, huge amounts of electronics (电子产品) are thrown away, instead of being reused. These goods often end up in landfills, where the chemicals inside them may be a danger to the environment. Electronics can contain harmful materials. If these materials get into the ground or water, the pollution can cause serious problems. Most electronics require metals. These metals must be mined from the Earth. Often the mining process creates serious pollution.
A group known as Waste Electrical and Electronic Equipment (WEEE) Forum is trying to make people more aware of the problems of e-waste. Recently, the WEEE Forum asked researchers from the United Nations (UN) to study a kind of e-waste that’s often not noticed because people don’t consider the goods to be electronics. The WEEE Forum calls this kind “unable-to-be-seen” e-waste.
The UN study shows that about 1/6 of all e-waste is “unable-to-be-seen”. Though it’s “unable-to-be-seen”, it’s certainly not a small amount. The “unable-to-be-seen” e-waste weighs about 9 billion kilograms. The WEEE Forum says that if this e-waste were put into 40-ton trucks and the trucks were then lined up, the line of trucks would be about 5,630 kilometers long.
The surprising kind leading the “unable-to-be-seen” e-waste group was toys. Worldwide, roughly 7.3 billion electronic toys are thrown away each year. These include goods like car racing sets, electric trains, and musical toys. They also include toys with electronic parts, like dolls that speak or games with electronic timers. In all, toys make up about 35% of “unable-to-be-seen” e-waste. But the problem is far larger than just toys. The report also shows that other everyday goods like home alarms, smoke alarms, power tools, and computer cables (电缆) are also big sources of “unable-to-be-seen” e-waste.
The WEEE Forum is hoping that as more people and governments become aware of e-waste, they will make a much greater effort to make sure electronics get reused.

4 . Over the last century, engineers all over the world have spared no effort to achieve the unachievable in bridge design.
Danyang-Kunshan Grand Bridge
No bridge is as long as the Danyang-Kunshan Grand Bridge in the world. The 164.8-kilometre-long bridge built in 2011 in China serves as part of the Beijing-Shanghai High-Speed Railway. The trip from Ningbo to Jiaxing that previously took 4.5 hours has been reduced to two, thanks to this bridge.
Rio-Niterói Bridge
Completed in 1974, the Rio-Niterói Bridge in Brazil is the second-longest bridge in all of Latin America connecting the cities of Rio and Niterói across the Guanabara Bay. The Rio-Niterói Bridge is technically known as a “box-girder (箱形梁)” bridge, made of special concrete. It receives an astonishing 140,000 (or more) vehicles per day.
Hartland Covered Bridge
The Hartland Covered Bridge is the world’s longest covered bridge. The 1,282-foot-long bridge was opened in 1901 and has been on Canada’s list of National Historic Sites since 1980. Although it was originally built without a roof, the bridge was capped with wooden materials during the repairs in 1921.
Jiaozhou Bay Bridge
The newly-built Jiaozhou Bay Bridge in China was named “world’s longest bridge over water” by Guinness Book of World Records in 2011, a title previously held by the Lake Pontchartrain Causeway. The dispute was settled when the title of “longest continuous bridge over water” was given to the causeway, with the Jiaozhou Bay Bridge receiving the title of “longest bridge over water”.

It was summer, and my dad wanted to treat me to a vacation like never before. He decided to take me on a trip to the Wild West. We took a plane to Albuquerque, a big city in the state of New Mexico. We reached Albuquerque in the late afternoon. Upon Paul, my dad’s friend, picked us up from the airport and drove us up to his farm in Pecos.
His wife Tina cooked us a delicious dinner and we got to know his sons Ryan and Kyle. My dad and I spent the night in the guestroom of the farm house listening to the frogs and water rolling down the river nearby. Very early in the morning, Uncle Paul woke us up to have breakfast. “The day starts at dawn on my farm,” he said. After breakfast, I went to help Aunt Tina feed the chickens, while my dad went with Uncle Paul to take the sheep out to graze (吃草). I was impressed to see my dad and Uncle Paul riding horses. They looked really cool.
In the afternoon, I asked Uncle Paul if I could take a horse ride, and he said yes, as long as my dad went with me. I wasn’t going to take a horse ride by myself anyway. So, my dad and I put on our new cowboy hats, got on our horses, and headed slowly towards the mountains. “Don’t be late for supper,” Uncle Paul cried, “and keep to the track (足迹；踪迹) so that you don’t get lost!” “OK!” my dad cried back. After a while Uncle Paul and his farm house were out of sight. It was so peaceful and quiet and the colors of the brown rocks, the deep green pine (松树) trees, and the late afternoon sun mixed to create a magic scene. It looked like a beautiful woven (编织的) blanket spread out upon the ground just for us.

8 . The biggest risk I’ve ever taken was quitting my job and biking alone across western China.
One of the best parts of the whole experience was the people. I met people from across China and once got to attend a Tibetan wedding-something I never thought I would do.
The people were some of the best parts of the trip, but mostly each day, I was alone with nature. Throughout the rolling hills and the flowing streams, western China is home to some of the most amazing scenery in the world.
It was indeed an experience I will never forget. If anyone has an interest in traveling, I would highly recommend going by bicycle!

9 . You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?
Jane Addams(1860-1935)
Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community (社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.
Rachel Carson(1907-1964)
If it weren’t for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world’s lakes and oceans.
Sandra Day O’Connor(1930-present)
When Sandra Day O’Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator(参议员) and, in 1981, the first woman to join the U.S. Supreme Court. O’Connor gave the deciding vote in many important cases during her 24 years on the top court.
Rosa Parks(1913-2005)
On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott.It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was,was tired of giving in,”said Parks.

Joy, a ten-year-old boy who loved nature, is always ready to help others, whether animals or humans. For example, he is always keeping water in a large basin in his yard for watering the birds and other animals.
One noon, he was playing on the grass in a bushy garden after school. He enjoyed the chirping (叽喳叫) birds, colorful butterflies, and two squirrels playing on the coconut trees. It was their own free kingdom, and Joy felt like an outsider. He decided to give them space to enjoy freely.
So he found an open grass and lay down, feeling like sunbathing on a greeny beach. Under the hot sun, Joy covered the eyes with his soft palms (手掌). His mind flew and thought about his class teacher Miss Shyla’s homework task — to do a good deed every day.
Joy stretched (伸出) out his hands, fed the squirrel some crazy biscuits and played with it. He felt the tiny eyes of a squirrel upon him. And just then, Joy saw a big rat spying on him from a hole. Upon seeing the big rat, Joy rose to his feet before it silently moving and running towards the hole. Finally, he failed to find the rat and the rat hid into its hole. Joy lay down again.
As he enjoyed the greeny beach and the sight of the blue sky, he couldn’t help but thought, “What a wonderful and blessed world it is! We humans should allow the animals to live as they wished.”
Suddenly, a tiny bird fell to the ground before his eyes. The bird shook several times and then lost consciousness (知觉). Joy jumped up and tried his best to wake the bird up, but failed. He thought the bird had fainted (晕倒) because of the heat. He couldn’t bear to see the little creature suffer and decided to take care of the bird.
