Q: Article: A few days ago we - that's me and the husband - took a cab to the station. Chat with the driver fell to the wrong of cyclists, and the misunderstanding of the road rules. So far as the rules of the road go, there seems to be one basic principle: when you are driving a car you hate bikes, when you are riding a bike you hate cars (and I guess walkers hate everyone). There is an obvious difference of viewpoint built in here. It wasn't until I started to drive a car (almost 20years after I had first rode a bike) that I actually realized that you could not see a cyclist at night without lights. In fact I now want to shout at late night cyclists without lights(like motortists once did at me): "You'll get killed, sunshine, I can't see you." The problem is that cyclists do ride headlong into danger. It's not just not having lights. It's biking on pavements (and so threatening to injure a load of innocent walkers in the process) and biking down one-way streets the wrong way. I admit that I do bike the wrong way down a one-way street sometimes. My feeble defense is that I try always to do it as if I know I was doing wrong. That is slowly, with an apologetic look on the face, and ready to get off at any minute. I can't bear the guys (usually, but not always it is guys) who do it as if they owned the place, and at high speed. So cyclists are not entirely innocent. But they are among the disadvantaged groups, because the bottom line is that a car or a lorry can kill a cyclist and not the other way around.
Answer: Not until she became a driver herself.

A: When did the writer realize the danger for late night cyclists without lights?

Q: Article: When Juliet was a child, she often went to the city park and played with her friends. On a sunny morning, when Juliet came to the park with her mum, she looked around and felt very unhappy. "What's the matter, dear?" asked her mum. Juliet replied, "Mum, there's so much trash on the ground." Juliet's mum looked around. There was paper, boxes and glass bottles everywhere. "What can we do?" asked Juliet. "I'm sure you will think of something," said her mum. As soon as Juliet and her mum went home, Juliet painted a picture of the park and wrote a sign in large black letters at the top of the picture. The sign read "PLEASE KEEP OUR PARK CLEAN". Later, she took plenty of bags and went back to the park with her mum. Juliet put up her picture on a big trash can . "Will you help me pick up the trash, Mum?" Juliet said as she handed her mum a bag. "I sure will," replied her mum. The children at the park ran over to see what was going on. Juliet handed them each a bag. "Let's clean this place up," said Juliet. Then they began to pick up the trash, talking and laughing. Soon all the bags were full. "We need to come back another day. There's still some trash on the ground, but the park looks much better," said Juliet. Her mum said, "So it does. _ "
Answer: Because there was too much trash at the park.

Q: Article: The $ 11 billion self - help industry is built on the idea that you should turn negative thoughts like " I never do anything right" into positive ones like "I can succeed." But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking? Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are. The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your dim friend that he has the potential of an Einstein, _ In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays opposing funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written. In this experiment, Wood, Lee and Perunovic measured 68 students' self-esteem. The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, "I am lovable." Those with low self-esteem didn't feel better after the forced self-affirmation. In fact, their moods turned significantly darker than those of members of the control group, who weren't urged to think positive thoughts. The paper provides support for newer forms of psychotherapy that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic perspective. Call it the power of negative thinking.
Answer: Encouraging positive thinking many do more harm than good.

A:
What is the finding of the Canadian researchers?
