Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees arc competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition “depending on who needs it”.
Nitrogen(氮) and carbon are shared through miles of underground fungi(真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons(神经元)in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn’t take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.The underlined sentence “the opposite is true” in Paragraph 2 probably means that trees .

In Europe, many people make friends across the borders between their countries through town twinning. Town or city twinning means two towns in different countries agree and decide to become “twins” with sister city relationship.
Their citizens find pen friends in the twin town. They exchange newspapers and stamps. The school teachers discuss teaching methods with the teachers in the twin town. Officials visit the twin town for celebrations. Ordinary citizens travel to the twin town, too, but not very often if it is far away.
Sometimes, schools even exchange their classes for two or three weeks! For example, German middle school students study for a while at the school in their twin town in Britain, staying with British families. A few months later, their British friends come to study in Germany.
Some towns even arrange exchange visits for theatre groups, choirs(合唱团)and orchestras ( 管弦乐队). Others send lecturers to the twin town who tell the people there all about their own town , and show photos and slides.
Town twining can help make friends and motivate(促进) people to learn from each other. It helps students to improve their language skills, and it contributes to (有助于)strengthening peace and understanding between different nations.Which is the best title for the passage?

There are many traditions around the holidays. “Holiday traditions” are things that people do every year during a holiday such as Christmas or Thanksgiving. At Christmas, for example, many people put up a Christmas tree or Christmas lights. These are Christmas traditions that have been going on for many years. But there is a “new” Christmas tradition that has become very popular: the TV firelog, a TV channel that shows nothing but a large log fire, blazing in a fireplace.
People put it on their TV and it makes them feel like they are watching and listening to a crackling fire. It makes them feel calm and comfortable. The origin(起源) dates back to 1986 in Canada. At that time, not very many people knew about it or watched the channel. Today, more than three million people watch the firelog channel during the winter holiday season. That year, the firelog channel was created(创造) to give the workers in the company that is now called Shaw Cable, a break at Christmas. By running the firelog during the holidays, everyone could go home for a few days and enjoy a bit of time off.
At that time, it was only broadcast to people in Edmonton but today it reaches people across Canada and beyond. This year, the Shaw firelog was updated. It is pretty high tech. Although it’s still really just a fire log that has been filmed, it has its own Twitter account (@ShawFireLog), its own Facebook page and it even has a computer App so you can see the burning log on a smartphone or a tablet. The Shaw firelog will burn until Jan. 5 on Shaw Cable, channel 222.What does this passage mainly talk about?

A family in Guelph, Ontario is spending a year living “in 1982”. They’re doing it so their kids can see what life was like before technology like iPads, computers and even coffee machines was part of everyday life.
They have stopped using all technology from their home and are relying on the things people would have used back in the 80s. There is a box at the front door where people can put their cell phones in, while they’re visiting the family.
Blair McMillan and his wife Morgan want their kids—Trey, 5, and Denton, 2—to have a year without technology.
Instead of reading e-readers, they are reading books. Instead of using a GPS, they used paper maps. The home the family is living in was built in the 1980s. Even the way they dress and style their hair is from the 80s.
The whole idea started when young Trey was called to come outside. He didn’t because he was busy playing on the ipad. That’s why his dad thought of the idea of living “in 1982” for a year. The family plans to live like “it’s 1982” until April next year. To them, one of the hardest things was giving up their cell phone.What will the visitors do when they come to see the family?
