The day is June 10.It has been snowing for the past four days in the Bitterroot Mountains.Wayne Fairchild is getting worried about our trek over the Lolo Trail-95 miles from Lolo Montana to Weippe in Idaho, across the roughest country in the West. Lewis and Clark were nearly defeated 200 years ago by snowstorms on the Lolo.Today Fairchild is nervously checking the weather reports.He has agreed to take me across the toughest,middle section of the trail. When Lewis climbed on top of Lemhi Pass,140 miles south of Missoula,on Aug.12,1805,he was astonished by what was in front of him;"high mountain chains still to the West of us with their tops partially covered with snow."Nobody in what was then the US knew the Rocky Mountains existed,with peaks twice as high as anything in the Appalachians back East. Today their pathway through those mountains holds more attraction than any other ground over which they traveled,for its raw wilderness is an evidence to the character of two cultures:the explorers who braved its hardships and the Native Americans who prize and conserve the path as a sacred gift. It remains today the same condition as when Lewis and Clark walked it. The Lolo is passable only from July to mid-September.Our luck is holding with the weather,although the snow keeps getting deeper.As we climb to Indian Post Office,the highest point on the trail at 7,033 ft,we have covered 13 miles in soft snow,and we hardly have enough energy to make dinner.After a meal of chicken,I sit on a rock on top of the ridge .There is no light visible in any direction,not even another campfire.For four days we do not see another human being.We are occupied with the things that mix fear with joy.In our imagination we have finally caught up with Lewis and Clark. Question: We can infer from the text that when crossing the Lolo Pass the author _ . - was attempting the impossible - was trying to set a world record - was following the trail of Lewis and Clark - was fighting with weather and taking unnecessary risks
was following the trail of Lewis and Clark

Read the following article and select the best answer. Article: Here are some of the strangest buildings in the world. Please look at them and tell us your impressions. Stone House, Portugal The stone house in Portugal is really similar to the famous home of the Flintstones (<<>> ). It is built between two rocks and its architecture has impressed some of the greatest architects. The house was attacked by some bad people. The house is pretty comfortable inside, with a fireplace and every- thing necessary, so it is a wonderful example of modern architecture in Stone Age style! Dancing Building, Czech Republic The Dancing House, or "Fred and Ginger", is situated in Prague, the Czech Republic. It is an amazing masterpiece of architecture which has its own romantic charm. There is something so sweet in the way the buildings hug each other for a dance! It has become a symbol of the city! The Crooked House, Poland The crooked house in Poland has an extraordinary and amazing structure. It was built in 2003 with its design based on the pictures of Jan Marcin Szancer and Per Dahlberg. It looks as if it has been taken from a cartoon: its design is "crooked", but it is balanced, so it is not ugly at all, just strange! The interesting part is how builders managed to create this genius idea, but the house is a fact and everyone admires their creativity! Habitat 67, Montreal, Canada Habitat 67 in Canada is a very interesting arrangement of cubes,which looks like the building blocks that children play with. It is pretty interesting how it was designed -- it looks so original, and at the same time the building is completely stable and comfortable for living! It was created as a main attraction for Expo 67, where it was officially exposed! Question: What is a common feature of the Stone Houseand the Dancing Building? - They all appear very modern. - They are the symbols of their own cities. - They are all for people to live in. - They are both examples of great architecture.

They are both examples of great architecture.

Read the following article and select the best answer. Article: The city can seem a cold, mean place. In the middle of so many people hurrying about their own business, a person can feel alone among the millions of others. There is a popular view that in cities, strangers are less likely to help an elderly person cross a street or call the police when they see a bike being stolen. Recently, a New Yorker named Casey Neistat did an experiment. He chained up his bike in several public places, then "stole" it in a number of obvious ways, such as using a hacksaw . He filmed everything to see whether other New Yorkers would try to stop a shameless bike theft. The result? People just walked on by. Is this evidence of an immoral, selfish urban society? Not necessarily. According to another recent study, the way city people mind their own business is about other factors besides morality . This is called the Bystander Effect, the theory that city people do not react because of the urban enviromnent they live in. Psychologist Dr. Harold explained why people did not involve themselves in Neistat's bike theft experiment with the Bystander Effect. First, people who live in cities are surrounded by so much activity that they stop noticing what is going on around them. Second, they are less easy to surprise and assume every activity has a logical explanation. "The third is that people notice it, but they don't know what to do," he continued. "And the fourth is fear -- they know they should do something, but they're afraid to challenge someone with a hacksaw." A lack of concern is only a small reason why people don't take action, concludes Dr. Harold. Despite the results of Neistat's experiment, there is also evidence of a sense of team spirit that connects people in cities. All it takes is a funny joke or a shared interest to start a conversation with someone at a bus stop. When city folk are in trouble, they come together for support -- famously in New York on City society is different, but that doesn't mean it's cold or mean -- it just means it's busy! Question: As can be inferred from the passage, the writer probably _ . - criticizes the loss of morality in urban society - feels sad about the result of Neistat's experiment - thinks city people are too busy to care about others - disagrees that city life sometimes can be cold and mean
disagrees that city life sometimes can be cold and mean
