Many years ago, most of our earth was covered with blocks (块) of ice. These ice blocks were as tall as high buildings in modern cities. Most of the ice was in the northern part of the world. Then the ice blocks started to move south. Cold and rain came with the ice. Animals had to move. At last, the ice began to melt (融化). After half a million years, most of it melted. More than half of the earth became covered with water. The climatebecame much warmer. Things began to grow. The earth began to look the way in which it looks today.

Imagine you are taking a walk on the beautiful beach. Just then, your feet step over something and you hear a crack (噼啪声) —an empty plastic bottle. Things like this are happening more often because of sea rubbish.
Studies show that 80% of all the waste is from the land. The waste is mainly plastics (塑料制品) which are really hard to degrade (降解). So the rubbish will remain there for a long time. Some of the pollution is caused accidentally. For example, about 10,000 product-filled boxes are lost at sea every year from business ships. Sometimes people just throw things into the water from boats or land. Many large rubbish areas are formed in the North Pacific Ocean.
Thankfully, the situation isn't ignored (忽视). Groups like the National Oceanic and Atmospheric Administration (NOAA) are taking action to help clean the sea. Since 2006,76 projects have cleared out 3,814 metric tons (公吨) of rubbish from the sea. Methods of rubbish cleaning include using machines to remove (移除) the waste away from the surface of sea water. Besides, special nets are set by the mouths of rivers to stop the rubbish before it reaches the sea. If everyone does his part, sea rubbish seems like a problem that can be solved.
26.The sea waste made of __________will remain for a long time.
A.paper B.wood C.plastic D.cotton
27.In the second paragraph we can know __________are also some of the sea rubbish.
A.special cleaning nets B.large factory machines
C.passing business boats D.lost product-filled boxes
28.In order to __________, some projects are done by different groups.
A.stop people from fishing B.fight against the sea pollution
C.develop trade in the seafood D.produce new kinds of plastics
29.In order to __________, special nets are set by the mouths of rivers.
A.prevent the rubbish reaching the sea
B.clean the surface of the dirty sea water
C.build more sea rubbish collecting areas
D.make people care about the environment
30.According to the passage, we can imagine the future of the sea will be__________.
A.terrible B.dark
C.quiet D.hopeful
四、任务型阅读

We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. 31 We take minerals (矿物) from the ocean. We can get salt by evaporating (蒸发) seawater.
32 such as gold. 33 Seaweed (海草) becomes food of many kinds—even candy and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can't drink ocean water. 34 But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea We pollute the ocean all the time. 35 Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.
A. Other gifts, such as seaweed, can be also got from the sea. B. Huge as it is, the ocean can't hold all that we pour into it. C. Along with salt, other minerals are left after evaporation. D. We even use their bones (骨头) for fertilizer (肥料). E. Some of its contents (所含物) may cause illness.

I am writing to tell you something about water.
Everyone knows that water is important to all living things. However, much water is wasted every day. What's worse, there are many people in the world that can't have clean water to drink.
As for how to save water, here is some advice from my classmates. First, we should do something small in our daily life. Fox example, we should turn off the tap as soon as we finish using it. Second, we can recycle water. Third, everyone should know the importance of water. Only when all the people work together can more water be saved.
Let's work together to save water!
Best wishes!
Yours
