For millions of years, the water we use today has been recycled(再循环)over and over by natural cycles that clean the water after we use it. But those natural cycles are no longer enough to clean all the waste that humans put into it, and our water has become polluted.
Man is polluting all water systems and the greatest concern is the pollution of our oceans (海洋).We are polluting the ocean in a number of ways. In fact, about 80 percent of ocean pollution has been people on land. Besides the pollution from land, another 20 percent or pollution is from
ocean-based activities.
First of all, large boats carrying oil cause much waste. In one recent year, our oceans had 1
serious oil spill and 7 medium-sized oil spills. Cruise ships are also big polluters. It has been found that an average-sized cruise ship produces around 1 million gallons of wastewater in one week.
What's more, the waste from ships and land, is another major cause of ocean pollution. One type of the waste is a big problem: studies have shown that 80 percent of ocean waste is plastic ( 塑料).Plastic waste can easily make fish and other sea animals die, such as whales, seals, dolphins, and penguins.
Finally, other human activities, such as the burning of fossil fuels（燃料），are also polluting our oceans. The CO2 produced not only pollutes the air but finally enters the oceans ecosystem. The world's oceans have taken in 40 percent of the CO2 emissions produced by humans.
Changes clearly need to be made as soon as possible to help make the ocean pollution less and less.

【答案】CADA
【解答】
1.词义猜测题 A.原因 B.决心；解决 C.担心 D.准备。根据前后句应该是最担心的是海洋的污染。
2.判断对错题 But those natural cycles are no longer enough to clean all the waste that humans put into it, and our water has become polluted.可知A对。The CO2 produced not only pollutes the air but finally enters the oceans ecosystem. 可知B错。First of all, large boats carrying oil cause much waste.可知C错。Besides the pollution from land, another 20 percent or pollution is from
ocean-based activities.可知D错。
3.文章结构 p1主要写自然循环已经不能够清理所有的垃圾了，水已经被污染了。P2最担心的是海洋污染。P3,p4,p5主要写什么造成了海洋污染。P6呼吁尽可能的减少污染。
4.主旨大意 从全文可以看出主要讲解水污染的起因。
