It is caused by a tiny worm which can penetrate the skin of a human being and cause a potentially serious illness. The larvae ( 幼虫) of these worms live in certain types of snails (蜗牛). When they are ready, the larvae (幼虫) leave the snails and enter the bodies of men and animals. In many African rivers there is a large animal called a hippopotamus (河马). It looks rather like an enormous sausage with short legs and a big mouth. Hippos spend much of their time in the river and they do not seem to serve any purpose. Because of this, some African governments ordered that the great animals should be shot on sight to provide meat for local people. When hunters killed most of the hippos in some areas, the number of cases of the disease increased rapidly. There were outbreaks of the disease in areas which had not previously experienced it. At first, thehealth authorities could not understand the reason why the disease had spread. They made investigations and discovered some very surprising facts.When they are in the water, hippos keep the muddy water in motion because they move about frequently. When they climb up on the river bank, they go in single file, making natural channels down which rain water can flow into the river. Without the hippos, mud gathered in the rivers and caused them to run over their banks. At the same time, rain water was unable to drain into the rivers easily, and this also helped to produce floods. Certain types of water snail breed rapidly on flooded land, carrying with them the larvae which spread schistosomiasis.Now African governments are importing hippos so that Nature can do her work properly and keep the water snails under control. This is one example of what happens when Man interferes with the work of Nature.在非洲和亚洲有一个非常严重的疾病称为血吸虫病（血吸虫病）。

And also they have the same degree and the same leading coefficient. Hence, the characteristic polynomial of C T is the same as p( ) .

Its frozen landscapes make the perfect setting for stories of survival, showcasing how both people and animals adapt to the ice and cold. Here are four of our favorite Arctic shows and movies.Nanook of the North（1922）This silent film from 1922 is a classic story of man versus （与…对抗）nature. It tells the story of an Inuit hunter named Nanook "The Bear" and his family as they struggle to survive in the harsh environment. Nanook of the North is one of the earliest documentaries - although some of the scenes were staged. Viewers are invited to witness how the Inuit people live. Audiences also see how the Inuit construct igloos one block at a time into icy, domed structures.Balto（1995）Based on a true story, this animated（动画的）movie takes place when a deadly disease strikes the small town of Nome, Alaska, in 1925.A half-wolf dog named Balto must lead a sled-dog team across the snowy expanse（宽阔区域）to deliver life-saving medicine to the town's citizens hundreds of kilometers away. Balto is not only an inspiring true story but an important look at the difficulties of Arctic travel and the brave people - and animals - that are relied on to save the day when people need them most.Arctic Tale（2007）Arctic Tale is a US documentary film about the life of a polar bear and her cubs as well as a walrus and her calves. Footage（素材）used for the film was shot over a 15-year period. The documentary gives an inside look at how these. Two Arctic animals grow from babies into adulthood as they learn how to hunt and survive in dangerous conditions. Throughout the film, the narrator reminds viewers that climate change is melting the Arctic ice and threatening the animals living there.Ice Road Truckers（2007 - 2017）This US reality TV series features truck drivers who must cross frozen lakes and rivers in remote Arctic land. They risk their lives to deliver much-needed supplies to small towns, diamond mines and offshore oil rigs（钻塔）.The series highlights the dangers of working in the Arctic and subarctic（亚北极的），as well as the bravery it takes to battle the icy storms and freezing temperatures.36.Why is the Arctic attracted to people to make films and TV shows？_____A. It has wonderful landscapes for animals to survive.B. People and animals find it easy to adapt to the icy cold.C. The Arctic provides ideal background for survival stories.D. Stories about the Arctic are very popular with young people.37.What do audiences know about the film "Nanook of the North"？_____A. They can catch a glimpse of the Inuit's daily life.B. Little can be known about how the Inuit build igloos.C. They can watch several earliest documentaries in the film.D. Nanook tells their story against nature in tough environment.38.Which of the following can best describe Balto（1995）？_____A. It is a make-up but inspiring story about a deadly disease.B. It is a story about how the Inuit trained dogs to save people.C. Dogs are the only animals that people can depend on in the Arctic.D. It is an encouraging story about Balto5s team overcoming difficulties.39.Audiences who are environmentalists may be interested in _____.A. Nanook of the North（1922）B. Balto（1995）C. Arctic Tale（2007）D. Ice Road Truckers（2007 - 2017）40.Ice Road Truckers mainly tells the audiences that _____.A. people have to cross frozen lakes to work in small townsB. people have to risk their lives to get much-needed suppliesC. drivers can earn some money in diamond mines and offshore oil rigsD. drivers need great determination to fight against the tough conditionBTraveling alone can be daunting. I have traveled by myself many times but, on every occasion, there was someone to meet me at the other end of the bus, train or plane journey. This time was different.Last week I had a holiday, from work, but none of my friends had the same week off. I decided that I still wanted to do something, so I booked a train ride to Toronto and reserved a bed in a hostel for one week.One week by myself. Would I be lonely Would I be bored？Quite the opposite. In fact, there are many benefits that come from traveling alone. Firstly, I was able to do whatever I wanted. I spent hours in museums that would have seemed boring and dull to some of my friends. I walked all around the city, which some people may have found too exhausting. Instead of relying on someone else to remember directions or to suggest activities to do, I discovered my independence and developed map-reading skills that I didn't know I had. I could get up and go to sleep when I wanted and I didn't have to wait for anyone else to shower and get ready every morning. Being in the safe environment of a hostel with like-minded travelers also gives a great opportunity to meet new people from all over the world, which can help combat loneliness.In spite of the benefits, I found that there were also some disadvantages of traveling alone.I missed having someone to talk to and to bounce ideas off. Experiences are often more enjoyable if they are shared, and part of the fun of traveling is the memories you have afterwards. Without a travel partner, I won't be able to laugh about and remember my Toronto adventure with a friend or family member in years to come.In addition, eating in a restaurant or cooking in the hostel was less fun on my own.I am very proud of myself for traveling alone, and I had a fantastic time in Toronto. However, in the future, I think I will always prefer to travel with another person or in a small group. Though, maybe it depends on who you travel with I would rather be by myself than with someone who is lazy, difficult and argumentative.41.What happened to the author last week？_____A.
