Twelve years ago, oceanographer Captain Charles Moore was skippering his yacht the Alguita in the North Pacific.He sailed into a mass of floating plastic rubbish which took him and his crew a week to cross.This floating rubbish dump is now called the Great Pacific Garbage Patch and doubles the size of the USA.The United Nations says there are now 18,000 pieces of plastic in every square kilometre of sea
everywhere in the world.A walk along any beach will give you some idea of the seriousness of plastic pollution.The trouble is, when we throw out plastic with the trash, the plastic doesn't go away.Plastic dnot biodegrade.It photo degrades into smaller and smaller particles which then enter the food chain.Plastics contain cancer-causing chemicals along the food chain in increasing concentrations and end up in our fish and chips, along with hormone disruptors.Scientists try to tell us that we are killing ourselves as well as other animals.At least 200 species are, as I speak, being killed by plastic.Whales, dolphins, turtles and albatross confuse floating plastic, especially shopping bags and six pack rings, with jellyfish.Some countries have rebelled and banned plastic bags.And the first was brave Bangladesh.Then China took the same decision.Botswana, Canada, Israel, Kenya, Rwanda, Singapore and South
Africa have also banned plastic bags.Notice how many of the world's richest countries are not on this list.It's an absolute disgrace.Think globally, act locally.A small Australian town is now one step ahead of the rest of the world.The inhabitants of Bundanoon in New South Wales have banned plastic bottles from the town.We need to follow their example and eliminate plastic from our lives, take care of the earth and vote for people we think will do the same.

People often speak of fire as though it were a living creature--It grows, dances, needs oxygen, feeds on whatever it can find, and then dies. And when a forest fire rages out of control, threatening human lives and homes, it must be fought like a "wild animal. " The fight is often desperate, since firefighters' hest efforts may be dwarfed by the fury of a large fire. But the fire's own traits can be used against it.
The heated air above a fire rises in a pillar of smoke and burnt gases, pulling fresh air in from the sides to replace it. Firefighters use this fact when they "fight fire with fire. " They start a fire well in front of the one which they are fighting. Instead of traveling on in front of the huge fire, the smaller fire is pulled back toward it by the updrafts of the larger blaze. As it travels back to meet the large fire, the smaller backfire burns away the fuel that the forest fire needs to survive.
Even when a backfire has been well set, however, the fire may still win the struggle. The wind which the firefighters used to help them may now become their enemy. When the backfire meets the main fire, before both die for lack of fuel, there is tremendous flame, great heat and wild winds. A strong gust may blow the fire into the treetops beyond the area, giving the fire new fuel and a new life.
This passage focuses on
A.how fires start
B.damage caused by fire
C.the fascination of fire
D.fighting forest fires
45、 A backfire is started
A.behind a forest fire
B.ahead of a forest fire
C.on the sides of a forest fire
D.all around a forest fire

Two hundred years ago, American students went to American schools. Like you, they studied arithmetic, spelling and geography. Unlike you, they also studied Greek and Latin. In fact, students spent more than half their time studying Greek and Latin.
The same was true for most students in Europe. Until the seventh century, all educated Europeans knew Latin. It did not matter if they lived in England or Italy or France or Spain. If they were educated, they knew Latin.
During the seventh century, educated Europeans began to study Greek as well as Latin. Greek and Latin had been the leading languages of the ancient Greeks and Romans. All educated Europeans were expected to know these languages.
To educated Europeans, the languages of the Greeks and the Romans were important. The ideas of the Greeks and Romans were also important. People knew that many of their own ideas had come from the Greeks and the Romans. To understand their own culture, they must understand its origin. They knew that those beginnings lay in the classical world.
Today we have so many things to study that few people have time to learn Greek and Latin. Few of you will study either language in school. Yet the ideas of the Greeks and the Romans are still important to us. These ideas still help to shape Western culture today. To understand our own culture, we must understand the culture of the classical world.
