AIn the19th century Americans from the eastern states moved out west to settle in the rich new lands along the Pacific Coast.The most difficult part of their trip was crossing the“Great American Desert”in the western part of the United States by horse and wagon.The western desert can be very dangerous.There is little water and there are few trees.But the desert is also scenery of great beauty.Tall towers of red and yellow stones rise sharply from the fat sandy valley floor.The scene has been photographed many times and appears in movies and on TV.In Arizona，man­made dams across the Colorado River have made two large lakes in the middle of the dry desert country.At Lake Powell，the red stone arch of Rainbow Bridge rises high above the blue lake.There are few roads.Many areas of Lake Powell’s shore can only be reached by boat or on foot.But hikers in this empty desert land sometimes find very old native American pictures，painted on the rocks.In Death Valley，California，the summer temperature rises to130—165degrees Fahrenheit.There is less than two inches of rain each year.Death Valley is the lowest place in America,925metres below sea level.In the1800s，many travellers died when they tried to cross this waterless Valley in the terrible heat.Although the desert is dry and seems empty，there is plenty of life if you look closely.Small insects，snakes，and rats have learned how to live in the desert heat.They live underground and come out at night，when it is cool.Plants such as cacti need very little water.When it does rain in the desert(sometimes only once or twice a year)，plants grow quickly，many flowers open in a single day.For a short time，the desert is covered with brilliant colour.1．In the19th century，Americans moved from the east to the west because they.

BWhen times get tough，we all look for ways to cut back.When we’re hungry，we eat at home instead of going out.We take buses instead of taxis.And we wear our old designer jeans just a few months long.With college expenses at all­time high，high school students are eager to do anythingto cut the cost of a university education.One cost­cutting proposal is to allow college students to get a bachelor’s degree in three years instead of cational institutions have been actively exploring ways to make the learning process more efficient.But there’s a question：Would the quality of undergraduate(本科生) education suffer？Few US universities have formally approved a“three­year degree”model.I doubt that mainstream North American colleges will carry out a three­year curriculum any time soon.For one thing，most universities already allow highly qualified students to graduate early by testing out of certain classes and obtaining a number of college credits(学分)．In addition，at famous universities，the committee who determine which courses are required and which courses are electives are unlikely to suddenly“throw out”one quarter of the required credits.Professors will resist“diluting(稀释)”the quality of the education they offer.In my opinion，a quality four­year education is always superior to a quality three­year education.A college education requires sufficient time for a student to become skilled in their major and do coursework in fields outside their major.It is not a good idea to water down education，any more than it’s not a good idea to water down medicine.If we want to help students find their way through university，we should help them understand early on what knowledge and skills they need to have upon graduation.We should allow students to test out of as many courses as possible.We should give them a chance to earn money as interns(实习生)in meaningful part­time jobs that relate to their university studies，such as the five­year co­op program at Northeastern University. 5．Which of the following can be the best title?A．It’s Time to Shorten the Learning ProcessB．Best Learning Takes Place Over TimeC．University Education Should Be Watered downD．College Education Calls for Reform答案B解析标题归纳题。
