3 . Should We Create More National Parks to Save Endangered Animals?

Don’t you find it worrying that more and more species of animals are in real danger of becoming extinct?     1     And I think the best way to do this is for governments to create more national parks.

    2     If this environment is destroyed — for example, when farmers clear a forest for new fields, or trees are cut down to make profits — many animals are unable to survive, and more species are likely to become extinct.

On the other hand, some people fight against the creation of national parks because they consider it is wrong to interfere with nature. They believe that wild animals are happier living in their natural environment.     4     They also point out that a few species are more likely to produce young animals in the wild than in national parks.

All in all, these disadvantages are far less important than the benefits of national parks.     5     As a matter of fact, they protect animals from their greatest enemies, that is, human beings.

4 . Corals are comeback creatures. As the world froze and melted and sea levels rose and fell over 30,000 years, Australia’s Great Barrier Reef, which is roughly the size of Italy, died and revived five times. But now, due to human activities, corals face the most complex condition they have yet had to deal with.

According to the Intergovernmental Panel on Climate change, a rise in global temperatures of 1.5℃ could cause coral reefs to decline 70-90%. The planet is about 1℃ hotter than in the 19th century and its seas are becoming warmer, stormier and more acidic (酸性的). This is already affecting relations between corals and the single-celled algae (海藻), which give them their color. When waters become unusually warm, algae float away, leaving reefs a ghostly white. This “bleaching” is happening five times as often as it did in the 1970s. Meanwhile the changing chemistry of the oceans makes it harder for corals to form their structures.

If corals go, divers and marine biologists are not the only people who will miss them. Reefs take up only a percent of the sea floor, but support a quarter of the planet’s fish diversity. The fish that reefs shelter are especially valuable to their poorest human neighbors, many of whom depend on them as a source of protein. Roughly an eighth of the world’s population lives within 100 km of a reef. Corals also protect 150,000 km of shoreline in more than 100 countries and territories from the oceans buffeting (肆虐), as well as generating billions of dollars in tourism revenue.

Coral systems must adapt if they are to survive. They need protection from local sources of harm. Their eco-systems suffer from waste from farms, building sites and blast fishing. Governments need to impose tighter rules on these industrials, such as tougher local building codes, and to put more effort into enforcing rules against overfishing.

Setting up marine protected areas could also help reefs. Locals who fear for their livelihoods could be given work as rangers with the job of looking after the reserves. Visitors to marine parks can be required to pay a special tax, like what has been done in the Caribbean.

Many reefs that have been damaged could benefit from restoration. Coral’s biodiversity offers hope, because the same coral will grow differently under different conditions. Corals of the western Pacific, for example, can withstand higher temperatures than the same species in the eastern Pacific, which proves a way forward to encourage corals to grow in new spots.

5 . I shall never forget the day when the earthquake happened. It was about 5 in the afternoon and I was _________ along the road to my daughter’s school. Our plan was to go_________ together. I stopped at a_________ to get some fresh fruit. We liked to have some fruit to eat after our swim. I was driving along a high_________ on my way to the school. _________ my road was another road which was built like a_________. I was_________ so I put the bag of apples_________ me and started to eat one. Suddenly I saw the cars in front of me start to_________ from side to side. I slowed down. Then my car started to shake! I didn’t know what was happening. Perhaps something had__________ wrong with my car. I drove a little more slowly and then I__________ the car and at the same moment the road__________ onto the cars in front of me. I found myself in the__________. I couldn’t move. My legs and feet were hurt badly and I couldn’t move them. All around me was__________. But below me I could hear shouts and a lot of noises.

Then I realized what had happened. I had been__________ an earthquake. For about two hours nobody came. Luckily I could reach the bag of__________，so at least I had plenty to eat. Then I heard people__________ towards me. A team of people had come to__________ if anyone was under the__________ road. I called out, “I'm here！” I heard a shout. Soon a stranger climbed to my car. “How are you__________？” he asked. “Not too bad,” I said. They didn’t get me out until the next morning.

6 . Why do we like drinking water form plastic bottles? Some people think it is healthy and clean. Others drink bottled water because it’s easy — you can carry it around with you. In hot countries, like Greece, they often buy bottles of cold water in summer.

However, making lots of plastic is not a good idea for many reasons. First of all, we need a lot of oil for plastic products. We usually use oil as a source (资源) of energy. If we reduced the number of bottles we made, we wouldn’t need so much oil. Plastic bottles also pollute the environment. If we recycled all our plastic bottles, we wouldn’t need so much space for rubbish dumps. But in Greece, they don't recycle much of the plastic they use. In 2006, Greeks recycled only about 10% of plastic waste. The rest became rubbish on land and in rivers and seas.

So next time you want to throw away a plastic bottle in the litter bin, stop and think. If you recycled it, you would help the environment. But what can you do when there isn’t a recycling bin near you? Well, there are lots of useful ways that you can use your bottles again. For example, an empty bottle makes a great piggy bank for your pocket money, and if you cut a bottle in halves, you will have a plant pot. Go green! You can make a difference.
