44. Sometimes a huge mass of snow slides down a mountain side. This is an avalanche. Avalanches happen when the snow on the mountain is disturbed by wind, earth movements, loud noises, or even by people skiing. __________ Dry snow avalanches move faster than wet snow -- at over 100 miles per hour. (A) The avalanche gets bigger as it slides down the mountain, carrying with it rocks and fallen trees. (B) Therefore, it is imperative that people should take precautions before they go on a skiing trip. (C) Avalanches cost hundreds of lives each year. (D) There is no way so far to prevent avalanches from happening.

45. The movie trilogy of The Lord of the Rings is a New Zealand production. The Maori and all New Zealanders have a strong respect for the land and various specific requirements are set up to protect their environment. There was a phrase that became a watchword on the film: “All that we ever leave behind are the footprints.” There was another reason to respect the natural environment used in the film. The author of the novel The Lord of the Rings, Tolkien, witnessed the devastating effects of industrialization and the way in which it changed, and even destroyed, great areas of the previously untouched English countryside that he knew and loved. _________(A) It goes without saying that he would have mistaken this landscape for the old English countryside that was no more. (B) Because of this, it seemed especially fitting that we should show our respect for this landscape and acknowledge that it was far more than a series of movie sets. (C) By all means, we have to convince people that all waste and garbage has to be removed and that everything has to remain the same. (D) Therefore, for any film-maker wanting to shoot on location in New Zealand, the commitment, in terms of extra budget and personnel, can be considerable.
