Take Time
It was Tuesday morning and Jake’s mother was driving him to school. As usual, they were driving down busy Fortieth Street. Jake’s mother was driving as fast as the speed limit and traffic allowed. Jake sat in the back seat, daydreaming as he looked out the window. They were passing a city park, and it flew past him quickly. “That park is blocking (阻挡) our way,” Jake’s mother said unhappily. “If I could drive right through it, we’d be at school in no time, but I have to drive all the way around it.”
The next day, as usual, Jake’s mother was driving him to school. Jake was looking out the window. Suddenly, he saw something shoot up from out of the trees. Just as quickly, it disappeared. At least, he thought he saw something, but they had speeded by so quickly that he was uncertain.
The following day, once again Jake and his mother were on their way to school. This time, Jake paid special attention as they passed the park. Tree after tree rushed by, when — there! There it was again! Jake wanted to find out what it was in the park, but his mother said he had a lot to do in the school and she was too busy to walk in the park. Jake begged his mother and she finally agreed to go and see it on the weekend!
On Saturday morning, Jake and his mother finally walked into the park and down a wooded path. Approaching (接近) the middle of the park, they discovered a large and lovely water fountain(喷泉). Every so often, it would shoot a burst of water high into the air. “Mom, this is what I saw shooting up out of the park on our way to school!” Jake said excitedly.
Jake’s mother smiled happily. “What an enjoyable walk! Let’s come here more often,” she suggested. “In fact, we don’t always have to drive to school. Let’s walk to school when the weather is nice, and we can walk through this park on our way.”
“Sure!” Jake happily agreed.

5 . Stress Management: How to Reduce, Prevent, and Cope with Stress
If you’re living with high levels of stress, you’re putting your health and happiness at risk. Stress does harm to your health. It may seem like there’s nothing you can do about stress.
Get moving
When you’re stressed, the last thing you probably feel like doing is getting up and exercising.
Connect to others
There is nothing more calming than spending quality time with another human being who makes you feel safe and understood. So make it a point to connect regularly — and in person — with family and friends. Keep in mind that the people you talk to don’t have to be able to fix your stress.
When you’re worn out by your morning traffic, or stuck in a stressful meeting at work, you need a way to manage your stress levels right now. The fastest way to reduce stress is by taking a deep breath and using your senses — what you see, hear, taste, and touch — or through a comfortable movement. By viewing a favorite photo, smelling a specific smell, listening to a favorite piece of music, tasting sweets, or hugging a pet, for example, you can quickly relax and focus yourself.
Effective stress management helps you break the hold stress has on your life, so you can be happier, healthier, and more productive. But stress management is not one-size-fits-all.
| A．Take control of your own life. |
| B．Learn to relieve stress in the moment. |
| C．They simply need to be good listeners. |
| D．But physical activity is a huge stress reliever. |
| E．But you have a lot more control than you might think. |
| F．That’s why it’s important to experiment and find out what works best for you. |
| G．While it’s not easy to avoid all stress, Learning about it can help you avoid unnecessary stress. |
6 . To deal with a big environmental problem, chemists have been thinking small. Really small. Their new tiny robot has one purpose: to help clean up tiny bits of plastic (塑料的) polluting waterways across the world.
Each new microrobot is no bigger than the tip of a sharpened pencil. They are magnetic (磁的) and shaped like stars. When sunlight hits them, they produce chemical reactions (化学反应) that push them through water in a specific direction. When they find a piece of plastic, they catch it and start to break it down. When the lights go out, they let go and are free to be used again. In a new study, the scientists reported that these robots can either break down a piece of microplastic or hold onto it to be collected later.
Chemist Martin Pumera at the Czech University of Chemistry and Technology in Prague led the project. He studies ways to build microrobots. He says: “Let’s make them do something useful.”
Pumera chose to center on the problem caused by microplastics. It’s a big problem. These are tiny bits of plastic, usually no wider than the top of a pencil eraser. And they’re everywhere — from the bottom of the ocean to air blowing onto ice at the top of mountains. They’ve turned up in drinking water, both bottled and tap water. Some studies found that too many pieces of plastic end up in the world’s waters. Plastic doesn’t easily degrade (分解) or fall apart. That’s always been one of its study points.
Pumera says his final goal is to make cheap and environmentally-friendly robots that can be used anywhere in the world. He thought that at first they might be most useful in plants that treat wastewater. There they can remove plastic before it reaches open water.
In lab experiments, the star-shaped swimmers catch each of four different types of plastic. And after a week exposed (暴露) to light, the robots had reduced the weight of the plastics. It wasn’t much — only by 3 percent. But that was a sign they were breaking the plastic down.
In fact, Pumera says they still have a long way to go. There are many types of plastics. And even these microrobots are unlikely to succeed in degrading them all.
The researchers also have not yet shown how safe this system is for the environment, although Pumera says that’s their next goal. The first real-world test will be in a waste water-treatment plant.

7 . Libraries around the world still hold copies of books printed hundreds of years ago. Will e-books still be used in hundreds of years’ time? Librarians are worried that digital information and digital books are already being lost. Technology is always changing, and even now, we cannot find the information typed in programs we used ten or fifteen years ago. Is digital data in danger of disappearing into a digital black hole?
Amazingly, we still have copies of the first published collection of William Shakespeare 536 plays The first Folio. That’s not bad for a book that’s nearly 500 years old. The folio was published in 1623. Around 800 copies were printed and 234 known copies still can be found today.
Books are quite easy to store. They hold a large amount of information in a small space. Most importantly, we don’t need any special equipment to open them. But what about the digital books stored on your computer now? Will people be able to read them in 800, 500 or even 10 years’ time?
Technology moves fast. The digital books we saved on some special equipment ten or twenty years ago can’t be opened now. We can’t open them on our 21st century laptops. What about all your digital photographs? Every second, thousands of them are uploaded to social media. There is no physical copy. What will happen to them? Will they be lost in a few years’ time? Now you save them in .jpg or .tiff format (格式). In ten years’ time, there will be another form and another program to open your photos with. This new program will not be able to open your old .jpg or .tiff files. People have recognised this problem and there are now online sellers who will print physical photo albums of your Facebook posts.
When a website closes down, all the information on that website is removed. It’s gone forever. It has disappeared into the “digital black hole”. Organisations have understood this problem. In 2004, the British Library in the UK started to archive (存档) websites that are important culturally and academically for future generations, just like paper-based literature. In 2010, the US Library of Congress signed an agreement with Twitter to archive public Tweets sent by Americans. They have archived all public Tweets sent since the start of Twitter in 2006. That’s 400 million Tweets every day!
With all the amazing new digital technology today, we still have to rely on the centuries-old technology of printing. For now, it seems printed copies are still the safest way to store information.
