Before you throw that old cell phone in the trash, or hide it away in a drawer, think again. There are actually many ways to dispose(处理) of a mobile phone that you are no longer using. First, you should be aware that in many places, throwing away cell phones is actually illegal because the batteries - especially in very old phones - can contain poisonous metals. 1.
You certainly don't need to pay to recycle an old cell phone. 2. This had led to many charities making a small amount of money by collecting old phones. There are large organizations that will take unwanted phones. However, you might also want to think locally.
3. And they do make a little bit on each donation. If you can't find a large cell phone recycling program in your area, you might consider starting a small local one, perhaps for a local public school.4. As people move to bigger and better phones, or smaller and better phones, there are plenty of old cell phones just waiting for a place to land, and smart schools have provided that place.
You might also want to hang onto any accessories( 配件) that you have. 5. Continuing to use accessories in good shape makes smart economic sense.
A.In fact, most companies that recycle them get paid to do so.
B.There are better places to get rid of them than your trash can.
C.Many schools and local charities now have recycling programs.
D.Local charities have contributed a lot in repairing unwanted phones.
E.Things like chargers or covers can often be used with your new phone.
F.The saying that one man's trash is another man's treasure certainly applies.
G.Check first, since so many schools have gotten the jump on recycling them already.
To deal with a changing world, we have to change as well. Transforming land into farms removes forests and worsens climate change. But we need to grow more food to support a growing global population. What can we do?
Scientists have discovered that plants grow best under a certain type of light, which can be provided by red and blue LEDs. The combination of these lights at the right level makes a space look pink. Since “pinkhouses” supply their own light, they don't need to have fragile glass walls and ceilings. And they can be set up anywhere, including places that don't get the amount of light greenhouses need.
Since pinkhouses can pack food in huge columns, one of these farms doesn't need a lot of land. Farmers can set up pinkhouses in cities. They completely control temperature and light, which can help some plants grow twice as well in pinkhouses as they do in traditional farming. Pinkhouses can allow for many more harvests per year since farming doesn't have to stop in the winter.
Even though pinkhouses are a great way to grow crops, lighting and heating an indoor space is very expensive. It doesn't make sense to grow foods that take up a lot of space or that we need to grow lots of, like wheat, rice, and corm, in a pinkhouse. We will still need to grow those crops in fields. We can start farming smarter.
Farmers will use satellite imagery to figure out exactly where to plant each crop. Think of a mixture of just the right crops, rather than a rectangle(长方形) of one type of plant.Sensors in the fields will measure the soil's water level,temperature, and chemical content. They will even be able to detect insects and send out notifications to a smartphone app.Irrigation systems will be tied to weather forecasting programs, allowing very precise watering and care, all calculated to get the best plant growth and yield.

A.covers lots of space B.needs enough sunlight

It has been a year since 1 first saw UBTech's Walker robot at CES 2019. I was blown away by its ability to perform many tasks.
A year later, it had come a long way, gaining much better motor skills and the ability to maintain balance. During a CES 2020 demo(演示), UBTech showed how far Walker had come.The robot walked over to a table, picked up a bottle opener and used it to remove the cap from a bottle of soda. It picked up the bottle and a glass and poured the liquid in, without spilling.During the demo, Walker also performed a number of serious Yoga( 瑜伽) poses, including standing on one foot and leaning back.
UBTech said that the ability to pour drinks required visual servo( 伺服系统) technology using its cameras to judge the position of objects. The same methods allowed Walker to uncap a marker and draw a picture of a flower on a piece of paper at another point in the demo.
All of the betterment was made via software as UBTech hasn't made any physical adjustments t0o the robot since we saw it last year. On the inside, the robot uses a combination of a few different operating systems on these internal PCs, including Ubuntu, ROS and Android. Its battery promises up to 2 hours battery life after a 2-hour charge time,
UBTech continues development on this pioneering robot, but doesn't have public launch date. The company is targeting Walker toward the home, with an emphasis on helping seniors or. just doing house cleaning. To make it stable enough to adapt to all these different conditions is a huge challenge. However, if development of Walker continues, this robot could eventually be a game-changer.

Every two or three months, Thyago Ohana goes out on the busy streets of Vienna with a sign saying "Free Hugs". The handsome 32-year-old Brazilian, who works in international trade at India's Vienna embassy, chooses a popular site, like the historic shopping street, Kaerntner Strasse. There he opens his arms to anyone who wants a hearty embrace(拥抱).
He does it because back in 2012, when he was feeling very stressed and anxious during a visit to Paris, a stranger gave him a free hug. He's never forgotten how it filled him with unexpected calm and joy.
For those who take up his offer, the hug makes them laugh and smile. But sometimes it does more, as when an elderly woman in a tour group stopped and watched him. The group moved on, but she remained and asked, "Can I have a hug?" "Of course you can!" said Thyago who wrapped his arms round her. When they broke their embrace, she kept holding onto his shoulders and looked into his eyes. "Thank you," she said. "I can't remember the last time I was hugged this way."
It's a memory that still makes Thyago emotional. "It was a really powerful moment of human connection. It's why 1 keep doing it."
Of our five senses, our sense of touch is the one that is most easily taken for granted. "A child can be born blind or deaf and they will grow up just fine," says David J Linden, author of Touch: The Science of Hand, Heart, and Mind. "Yet if a baby is lacking in loving social touch for the first two years of life, then all sorts of disasters unfold." That's one reason why when babies are born, they are now usually placed on their mother's skin.
Linden says however you do it, "maximizing touch in your life is a good thing"- whether holding hands, petting a dog, going to the hairdresser, hugging our kids, our partners or even a
stranger.

A.Our sense of touch isn't so important.
B.Our sense of touch is undervalued.
C.Our sense of touch does no good to us.
D.Our sense of touch is thought highly of.
3.What does David J Linden think of social touch?
A.The way of offering social touch counts.
B.Offering hugs is the best way to get social touch.
C.Blind kids will be cured as long as they get enough social touch.
D.Many problems can be tracked back to babyhood short of social touch.
