The world itself is becoming much smaller by using modem traffic and modem communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems, 1. Pollution means making things dirty. It comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. 2. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place，Man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.

Dogs were living as companions to the early settlers of North America over 10,000 years ago.
The oldest domestic dogs in the Americas were thought to be around 9500 years old. Angela Perri of Durham University, UK, and her colleagues have carried out fresh radiocarbon dating on the two dog skeletons that gave this date, discovered in the prehistoric Koster site in Illinois, and found they were even older: around 10,100 years old.
A third dog from another Illinois site called Stilwell II was older still，at 10,190 years old. That makes it the oldest known domesticated dog in the Americas.
The team concluded that all three dogs were domesticated as their skeletons were complete and unskinned, and so hadn’t been butchered for food. They had also been carefolly buried, evidence they were valued by their owners. The Stilwell II dog, which probably resembled a small English settler, was under what seemed to be the floor of a living area.
It is unclear why it took so long for tame dogs to arrive in the Americas, given that they were domesticated at least 14,000 years ago in Eurasia. By this time, people were already moving into North America from Siberia; there is evidence some reached Chile 18,500 years ago. Geneticists have found signs of at least three waves of migration over the following millennia. There is no evidence that domestic dogs accompanied them.
“We don’t know if dogs were part of the first waves of immigration to the Americas” says Luc Janssens of Ghent University in Belgium. “It could be so, but no archaeological bones have yet been found.”
It is “overwhelmingly probable” that some of the early settlers did bring dogs to the Americas, but they may not have had “the time or the spiritual compulsion to bury them’％ says Pat Shipman of Pennsylvania State University.

When was the last time you used plastic plates? Next time, why not try some edible ones? You’ll help the environment and your guests won’t go hungry.
“I used to work in school catering and saw a lot of money being thrown away. I thought that was criminal, so I decided to do something about it,” said Italian school chef Tiziano Vicentini.
Now, Vicentini has an amazing range of edible plates for schools. The plates are made out of bread dough, so you can eat them afterwards. “These dishes cost a few pennies each and are either eaten by the kids, or go into recycling bins for animal food,” explained Vicentini, 50, of Milan.
But now other companies are developing edible plates, too. The Edible Plate Company offers edible plates, bowls, trays and cups. Their products are environmentally-friendly, 100% biodegradable and can be used for all types of catering and home use. And they’re made from a natural plant. After use, they can be fed to animals or left to degrade naturally. They also have a range of cutlery (餐具）made from corn and potato starch (淀粉).
These plates will also help reduce the amount of plastic we create. Waste from plastic causes damage to the environment, costing governments millions in waste management. Plastic bags often end up in landfill sites. And the burning of plastic waste causes toxic gases that pollute the air.
In response to this, governments around the world are introducing tough recycling regulations. And many shops are offering biodegradable plastic bags and eco-safe packaging on their products. To help matters, the International Organization for Standardization (the ISO) has also developed a system to evaluate the biodegradability of products, with a certification and logo scheme. Meanwhile, how about a nice plate for lunch?

D. The damage to the environment caused by plastic waste.
4.What is the main idea of this passage?
A. The measures to stop the pollution.

D. The plate solution to eating and environmental problem.
A new family moved in next door and I got to meet the mother of the family, Lydia.
Lydia is Korean, and her family moved to our city so her husband could go to graduate school. We started talking, and she was apologetic about how bad her English was, but I didn’t care. I knew how hard it was to learn a second language. I enjoyed chatting with Lydia as we watched our kids play.
It was what came next that challenged me: Lydia asked if I’d be willing to help her with her English.
Now, I am not a teacher. I admire teachers, and I’m grateful for teachers, and it’s because I admire what they do so much that I was very, very sure that I couldn’t do it myself.
But Lydia was sure that she wanted my help. I was doubtful. I wasn’t sure my “help” was even worth being called by that name.
But because she asked me, I said “yes.”
And that was the beginning of 过 friendship. Lydia and I spent afternoons sitting together and reading the newspaper, and as we did, she asked me questions when she had them — questions about language, yes, but also questions about the new culture she found herself in.
In turn, I asked my own questions, growing curious about her home country and culture. We bonded over our shared faith and our struggles as mothers of kids with special needs. When I complimented (恭维)her cooking, she began to teach me about Korean food, eventually leading to a shared trip to explore the Korean grocery stores in our city.
Because of Lydia, I learned more about my own hometown than I ever could have learned by myself.
I’m still not sure that I’m any good as a teacher. But I’m grateful I said “yes” when my neighbor asked me to help her with her English. That meant spending extra time with my neighbor, and that extra time meant she didn’t remain just my neighbor. She became my friend.
1.What was Lydia sorry about?
A. Her bad English. B. Her carelessness.
C. Nobody teaching her English. D. Her poor life in a new place.
2.What can be concluded from the fourth paragraph?
A. The author admired teachers.
B. The author wanted to be a teacher.
C. The author didn’t want to help Lydia.
D. The author was not confident in helping Lydia.
3.Why was the author grateful at the last paragraph?
A. She managed to learn English well.
B. She made friends with her neighbor.
C. She learned how to cook Korean food.
D. She realized her dream of being a teacher.
4.What can we learn from the passage?
A. No pains, no gains.
B. A friend in need is a friend indeed.
C. To help others is to help ourselves.
D. Where there is a will, there is a way.
