Passage 7 Nature does not hurry, yet everything gets done. Many great natural wonders need millions 1 years to finish. A friend of mine 2 (see) many natural wonders since he was fifteen. Last summer he visited a big ice cave. Ice caves are one of 3 (cold) natural wonders on Earth. Inside the cave, ice covers almost everything. The ice walls look 4 (shine) and blue. He told me it was hard 5 (walk) inside because the ground was very slippery. He decided 6 (take) as many photos as he could. 7 the view was fantastic, tourists must be very careful. One small mistake may bring danger. People are not allowed 8 (touch) the ice. We should respect 9 (nature) power and keep these ice caves safe 10 future visitors. Passage 8 What will our natural wonders be like hundreds of years from now? This is a question 1 makes many scientists think hard. Some natural wonders are disappearing. Warmer weather, pollution and human activities hurt 2 (they). If we do nothing, some amazing views 3 (lose) forever. My geography teacher often tells us that every person can do something 4 (help). We do not need to travel far 5 (see) great wonders. We can start with small natural places around us. We should enjoy 6 (watch) the beauty of nature, but we should also remember 7 (protect) it. It is not only scientists’ work 8 also our own duty. 9 (million) of young people hope that future generations can still enjoy these wonderful gifts 10 nature.
