Imagine an area 34 times the size of Manhattan. Now imagine it covered ankle-deep in plastic waste---- a total of about 19 billion pounds of garbage. 1..
“We're being overwhelmed(淹没)by our waste，”said Jenna Jambeck, an environmental engineer who led the 2015 study that determined this astonishing number. 2., unless something is done to stop the tide of garbage.
Plastic----a widely-used material----has in many ways been a benefit to humans but it has also caused a growing problem. Today, plastics are the No.1 type of garbage found in the sea. Ocean Conservancy, a nonprofit that organizes an annual coastal cleanup event worldwide, said plastic waste makes up around 85 percent of the garbage collected from beaches and oceans.
Ocean Conservancy says plastics are believed to threaten(威胁)at least 600 different wildlife species(物种). 3. ; a growing body of evidence suggests humans are consuming plastics through the seafood we eat. A research suggests some plastics could be poisonous to humans, and could potentially increase the risk of health problems.
4.. At the Economist World Ocean Summit this week, ten nations announced to reduce plastic sea liter as part of UN Environment's CleanSeas campaign. 5.Corporations also have a role, as do individuals. We can start by thinking twice before using single-use plastic products----and when we do use them, we should take care to properly throw them off or recycle.
A. The following is what we should do
B. And it's not just wildlife that's threatened
C. And this figure is likely to double by 2025
D. But it's not just countries that need to do their part
E. By 2050,that figure is expected to rise to 1000 pieces
F. That's how much plastic waste ends up in our oceans every year
G. All of us have an important role to play in dealing with the problems
Skyscrapers are the symbol of Urban life.City people are used to seeing tall buildings and apartments. Farms，on the other hand,are associated with rural(农村的)life.However，there are experts who think skyscrapers should become farms to meet the increasing food needs.
By the middle of this century, some scientists suggest，almost 80% of the earth's population could live in cities. In addition，the population could increase to 9.1 billion people during that time yet the amount of land available for farming will be the same.If current farming practices don't change，we will need an area of new land to produce enough food for the planet.
Vertical farms, where urban farmers could grow crops in environmentally friendly skyscrapers, could be the solution. In spite of concerns over high costs, experts want to make it a reality and use these skyscrapers to grow crops.
Vertical farms would have many advantages, supporters say. Unlike traditional farming, vertical farming could be free of chemicals and diseases. Besides, crops would not suffer from problems like flooding. Finally，vertical farms would reduce the cost and negative effects of transporting food over long distances.
Some argue that although crops growing in a tall glass building would get natural sunlight during the day，it wouldn't be enough. For this reason，vertical farms would need additional light sources(来源), such as artificial light.
Another way of growing fresh food is to build urban farms on rooftops. This more practical approach may be more achievable than the idea of farms in skyscrapers, researchers suggest. Experts agree that innovative(革新的)farming practices are needed to support the need for more food at affordable costs, both to the farmer and to the consumer,but the best ideas could be yet to come.
1.What primary problem could vertical farming settle？
A. Poor state of rural life.
B. Shortage of food supply.
C. High cost for transporting crops.
D. Environmental pollution by transitional farmings
2.What is the advantage of vertical farming?
A. It can produce organic food.
B. It requires little care.
C. It can benefit transport industry.
D. It needs very low cost.
3.What is a big challenge to make vertical farming a reality?
A. Farmable land. B. Crop diseases
C. Light sources. D. Climate conditions.
4.What can be the best title of the test?
A. Future Food Needs
B. Symbol of Urban Life
C. Farming on Rooftops
D. Farms of the Future
When my grandmother died at the age of 96, there were two things she left behind in abundance---nearly 100 photo albums documenting decades of travel and home life, and a dozen quilts, one of which my mother gave me.
Quilting is the process of sewing together fabric(作料)to make one large piece of fabric. In my family，quilting and sewing is a tradition that has been passed down through the generations. My mother says her great-grandmother would occasionally travel around New York State to sew clothing for other families.
In the United States，quilting was a craft(手艺)that started as a necessity and eventually became much more. In 1862, the U.S. government offered millions of acres of land to Americans who wanted to move west. This allowed families to settle on land that that could eventually own. They often built their own homes and lived off the vegetables in their gardens and the livestock they had. Sewing was very important for women because they were responsible for clothing their families and keeping them warm.
Quilting also became a chance for women to socialize with each other.They would gather for so-called “quilting bees”，where they would meet up and work on one quilting project together. This provided a much-needed relief from the lonely life of living on a large piece of land.
Throughout history, the different patterns on American quilts have conveyed all kinds of information. From then，we can tell where a person lived，what region of the world they originated from, or sometimes a story is told in pictures on a quilt.
Even today，women still gather to quit together in a show of friendship and a love for the craft，just like the old days.My sister has tried quilting a few times，and hopefully，her two daughters may one day continue this family tradition.

Ashley Power's mother bought a computer for her when she was eight. When she was thirteen, she was surfing the Internet on a regular basis, but she couldn't find anywhere for teenagers to meet and talk. And one day she thought, "If I had my own website, I'd make it a really interesting site for teenagers."
