1 . The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.
As far as the Internet being a part of our lives. - Well,that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure (血压) in a young group: teenagers.
The study results show that teens who spend at least 14 hours a week only may cause high blood pressure, which makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and other diseases.
The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 0f the teens were described as "heavy Internet users". And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure.
The lead researcher is Andrea CassidyBushrow. She said, "Using the Internet is part of our daily life, but it shouldn't ruin us. " Ms. Cassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn't let their children use the Internet for more than two hours a day, five days a week.

3 . Traditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot-one that draws inspiration from an octopus (章鱼).
Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search，rescue and exploration. “The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots” the study’s authors wrote.
Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains (地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’re made out of hard and heavy parts that could be potentially dangerous to their users.
So researchers have been working on building soft robots for decades. They’re taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.
But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts, such as a source of power.
“Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology’ Center for Micro-BioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”

4 . Welcome to Olympic National Park!
The park is located in the western state of Washington and it covers more than 400,000 hectares. Each area of the park offers visitors something special. Here are some places to go.
Elwha Valley
The Elwha Valley is in the central part of the park. It is the Olympic Peninsula’s largest watershed (分水岭). Long ago, the rivers in this area held the most salmon (鲑鱼) outside of Alaska. In the 1920s, a growing community of settlers built two hydroelectric (水力发电) dams to provide energy for the local economy. The dams created many problems for the river. They decreased the water in the rivers, which caused the fish population in the area to decrease. This affected the other animals that depended on fish for food.
The community later decided to take some measures to solve these problems. Today, the Elwha River is the site of one of the largest ecosystem restoration projects in National Park Service history.
Hurricane Ridge
Hurricane Ridge is a mountain area in the northern part of the park. It is easy to enter, and provides incredible views of the Olympic Mountains.
The ridge has many hiking paths. In winter, people come here to ski. They also come here to take part in other fun winter activities, like sledding and snowboarding.
Hurricane Ridge usually has snow from December through the end of March. Visitors must be prepared for icy roads and severe weather.
The Coast
The westernmost part of the park is Pacific coastline. Olympic National Park has many breathtaking beaches.
Rialto Beach is known for its tall seastacks (海蚀柱). These formations are tall towers of rock standing in the sea. Kalaloch Beach is known for its white sand. It also has three national wildlife refuges, which protect the area’s bird and fish species.
The coastline areas offer hiking and camping. They are some of the most popular places in the park.

“You can’t say it’s not a great university, just because Papa went there.”
“That’s not it at all. And it is a top university.” She was still holding the pieces in her hand. “But we can’t afford to send you to college.”
“I wouldn’t dream of asking you for money. Do you want me to get a job to help support you and Papa? Things aren’t that bad, are they?”
“No,” she said. “I don’t expect you to help support us.”
Father borrowed money form his rich cousins to start a small jewellery shop. His chief customers were his old college friends. To get new customers, my mother had to help. She picked up a long-forgotten membership in the local league of women, so that she could get to know more people. Whether those people would turn into customers was another question. I knew that my Parents had to wait for quite a long time before their small investment could show returns. What’s more, they had not wanted enough to be rich and successful. Otherwise they could not possibly have managed their lives so badly.
I was torn between the desire to help them and change their lives, and the determination not to repeat their mistakes. I had a strong belief in my power to go what I wanted. After months of hard studying, I won a full college scholarship. My father could hardly contain his pride in me, and my mother eventually gave in before my success.

9 . TEENAGERS lead an exciting life in high school, making friends and dreaming about the future. However, as all young people know, teenagers have plenty of worries too.
Do you know what British teenagers worry about most? A survey by the UK’s Department of Health shows that the top worries are losing weight (减肥) and fitting in (适应). Over 100,000 teenagers took part in the research.
Losing weight is a big concern among teenagers. This may be an effect of famous people with perfect bodies around them.
Adolescence is a physically and emotionally difficult time. Teenagers want to feel good about their bodies.
It’s also important for them to be accepted. Many teenagers were picked on (作弄) in high school. “Who should I eat lunch with?” “Who should I hang out with?” “Will I be accepted?” These questions are troubling many UK teenagers, according to the survey.
It’s interesting to see that family background has an effect on teenagers’ worries. Teenagers from low-income families worried more about losing weight and bullying (欺凌弱小). Teenagers from higher income families were more likely to worry about fitting in and peer pressure (同辈压力).
