More cycling, better public transport and car bans… Places all over the world are taking a range of measures to lower traffic pollution.

Paris

    Paris bans cars in many historic central districts on weekends, places odd-even(单双日制的) bans on vehicles, makes public transport free during major pollution events and encourages car-sharing programs. A long section of the right bank of the river. Seine is now car-free and a monthly ban on cars has come into force along the Champs-Elysees.

The Netherlands

    Politicians want to ban the sale of all petrol cars from 2025, allowing only electric of hydrogen vehicles. The new law will allow anyone who already owns a petrol car to continue using it. Most cities encourage bicycle use.

Freiburg

    Freiburg in Germany has 500km of bike routes and a cheap and efficient public transport system. One town, Vauban, forbids people to park near homes and makes car-owners pay 18,000 for a space on the edge of town. In return for living without a car, people are offered cheaper housing, free public transport, and plentiful bicycle spaces.

Curitiba

    The southern Brazilian city of two million people has one of the biggest and lowest-cost bus systems in the world. Nearly 70% of its people go to work by public transport and the result is pollution-free air and traffic-free streets.

Copenhagen

    Copenhagen prioritizes(优先考虑) bikes over cars and now has more cycles than people. The city calculates that one mile on a bike is worth $0.42 to society, while one mile in a car is a $0.2 loss. Large parts of the Danish capital have been closed to vehicles for decades.

    The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

    I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to compete and then do better than their human ancestors. Once they do better than us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to improve environments. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

    Sometimes I have to admire people's imagination but what I admire most is the businessmen's sense of smell. China's Singles Day, which falls on Nov. 11 every year, has far surpassed its U.S. counterparts of Black Friday and Cyber Monday—combined. Last year, Americans spent a record $12.8 billion online between Thanksgiving Day and Cyber Monday. It's impressive until you compare it to the $17.6 billion in sales made by Chinese consumers in a single 24-hour period during 2016's Singles Day.

    Singles Day is known as “Bare Sticks Day” or “Bare Branches Day” in Chinese—because the date “11/11” looks like bare branches and “one” is the loneliest number. Singles Day began in the early 1990s in the dorm rooms of Nanjing University when a group of single friends were sorry about the lack of significant others and decided to mark the day by organizing activities as a group of singles and reducing their loneliness by buying themselves a gift.

    Then in 2009, sensing s break between the sales period of China's National Day on Oct. 1 and Chinese New Year in late January or early February, Alibaba's Jack Ma saw an opening: sell to comfort lonely hearts.

    The first year did only $7.5 million in sales, but just 8 years later, shoppers spent $25.3 billion, or 168.2 billion yuan, this year—a 40 percent jump from last year's $17.6 billion. Foe comparison, Black Friday and Cyber Monday in the U.S. only netted $6.79 billion in 2016. Amazon doesn't release sales figures for July's Prime Day, but it's pretty safe to believe the not-quite-national-holiday doesn't come close to $25 billion.

    “More than $25 billion in one day is not just a sales figure,” Alibaba Group CEO Daniel Zhang said in a statement. “It represents the desire for quality consumption of the Chinese consumer, and it reflects how merchants and consumers alike have now fully accepted the combination of online and offline sales.”

    In no particular order, here are some songs on the Music app of my phone:

On a Sunday Afternoon by Lighter Shade of Brown— A student of mine introduced this rap song to me all the way back in the early 1990s, when I was teaching Spanish at a local university. The story in the song takes place not too far from where I live in Los Angeles. It's a good "driving" song, nothing difficult or "deep".

Say Something by A Great Big World—A more recent song about a couple losing contact with each other. The piano part is of very little playing but beautiful.

    The Weight by The Band — Another old song, originally made public in 1968, but one I didn't hear until I was in high school more than 10 years later. I don't understand the words to the song completely, but the feeling of the song is very comforting to me.

Under the Bridge by Red Hot Chili Peppers — This Los Angeles group wrote a song that I used to listen to when I first moved to LA more than 25 years ago. I didn't know anyone here when I first arrived. When I got bored, I used to drive up and down the major streets that cross the city from east to west, listening to this song about t4the city of angels" being as "lonely as I am" (Don't worry. I have plenty of friends now.)

    My challenge for you is this: to read a book for 15minutes every single day for a month.

    Let me explain a bit, by telling you where the challenge came from. I have many things in common with my dad, like music taste and sense of humor, but sadly reading isn't one of them. I can happily spend a whole day with a book, but my dad can't read a book for longer than about 5 minute. He reads emails, websites and papers for work, but not book. He's busy, so I think sitting down to read for just 15minutes a day is a good way to relax and to introduce him to reading.

    My dad is not the only person who avoids book. I know lots of people would rather relax on their computers or in front of the TV. Everyone is different and has their own interests, but I think there are lots of benefits to reading, which screen﹣based activities don't have.

    Firstly, it's better for your eye. Looking at screens can be very stressful for your eye muscles, and clearly you should avoid looking at screens for an hour before bed, to get a good night's sleep.

    One thing I personally love reading, is being transported to another world﹣I often forget the time or things around me! Reading is a great way to switch off before you go to bed, because you think more about the world of the book, rather than the real world, so you can truly relax. I know you can be transported to a different world in a film or a TV show, but I think books do it better.

    I also enjoy hearing what people are doing and finding out what they think. Reading gives me the chance to get to know hundreds of new people! It also teaches you to see things from other people's point of view, and understand other people's decisions or opinion. With a book, you can hear everything a character is thinking or feeling﹣you really can be inside someone else's head!

    So give it a go! Take 15 minutes when you are waking up, going to bed, eating lunch, or having a coffee. If you read a lot, why not try 15 minutes of an English book, or pass the challenge on to someone else？ Good luck, and happy reading!

    I'm a single person and live with my dog. Jed isn't just my dog. He is my family. He goes everywhere with me. So I was overjoyed last year to hear that Bunnings was allowing dogs on a leash(皮带)- into their stores.

    But no sooner had the rule come in than it was quickly repealed(撤销). A little girl in Victoria had walked up to a Jack Russell in a store and been bitten(咬伤). That was it. No more dogs.

    I don't know the whole story. But here's what I have to say: dogs bite sometimes and kids are sometimes difficult to control.

    There is nothing I love more than a kid who wants to touch Jed. But what's even better is when they ask permission first.

    I was at my local dog park last week. It's huge, with an off-leash dog area to one side and a fenced-off kids' playground a good distance away. There was a family there that morning —parents and two young girls playing near the dog area. The elder girl started crying at the sight of Jed—" puppy! There a puppy! "Jed went right up and started licking(舔)her, which only made her cry louder.

    My dog was frightened and tried to get away. The little girl ran after him, shouting loudly. The parents did nothing; they just let their kid frighten my dog and then said I should have stopped him from licking her.

    While they had a choice to play elsewhere, I did not. So I had to walk Jed away.

    "I just don't want to have to meet a dog when I go shopping," said one caller on a radio show yesterday. Look, I get that. But the thing is, I don't always want to have your kid kick the back of my seat for two hours on a plane.

    When I lived in the UK and the US, I couldn't walk through the stores without stopping to pat dogs. Why can't we follow their practice?
