Exploring nature allows us to catch sight of rare animals and come across special places of beauty. Of course, none of this would be possible 【小题1】 protected nature areas. This is 【小题2】 national parks are so important. A few national parks allow things like hotels and recreation areas 【小题3】 (construct) within them, but most parks do not allow any development at all.

The very first national park 【小题4】 (be)also one of the most famous in the world—Yellowstone, in the western USA. Nineteenth-century explorers 【小题5】 (amaze) by what they saw in Yellowstone. Apart from the beautiful mountains, 【小题6】 (rush) rivers, and tall waterfalls, there were geysers, which sent boiling water as high as 91 meters into the air. Then there were the hot springs, as colourful as rainbows. These explorers wanted to protect the natural 【小题7】 (feature) of the area from development so that future generations could enjoy the area. And so, in 1872, Yellowstone was established as 【小题8】 national park. Today, around four million people a year visit it. Many come hoping to see wildlife, 【小题9】 is no longer as common in the American West as it once was. Everyone comes to see the geysers, 【小题10】(especial) Old Faithful, which sits near the centre of the park, and sends 95. 6 ℃ water up to 56 metres into the air every 44 to 125 minutes.

With the development of science and technology, our life is becoming much better and more convenient. However, more garbage and pollution【小题1】(produce) at the same time, which【小题2】(lay) a heavy burden on our environment.【小题3】is known to all, environment plays a vital role in our daily life. In response to the severe situation, we should take effective【小题4】(measure) to protect the planet where we coexist. It is suggested that we should sort waste【小题5】(relieve) the situation.

Garbage classification, which is a good way to protect our environment, can’t be overemphasized. It can help separate recyclable waste, which can be【小题6】(full) used to help save the resources【小题7】a large degree. Not only can we make our environment clean and beautiful, but also recyclable waste can be made good use of to benefit us in return.

As garbage classification is significant, we should take【小题8】active part in putting it into practice. It’s a must for【小题9】(we) to learn to sort waste. It is the little things we do today that have a profound influence on the planet. Only if all of us make joint efforts can we make a big【小题10】(different) and have a good environment.
