Choosing a mountain bike that's right for you is easier than learning how to ride it．Keep these tips in mind when shopping for a mountain bike and you won't fall off．
Decide how you are going to use your new mountain bike．
Are you a novice rider who simply wants to cruise the great outdoors on the weekends, weather permitting? Do you intend to test yourself on the rough roads, every day, rain or shine? Or are you going to use your new mountain bike to ride to and from school or work? For every type of riding, there is a mountain bike made to do it．Be honest about your intentions, and you're more than half way toward choosing the right mountain bike for you．
Visit your local bike shops．
Any good bike shop will stock a wide range of quality mountain bikes in all price points and sizes．Your local bike shops will carry more than one brand of bicycle．And these shops are staffed by people from your community who know and love bicycles．Not only will they sell you a mountain bike that suits your needs and fits your body, but they will service what they sell．Visit at least a few shops．You'll get a feel for the ones suit you right away．
Don't be shy．
Tell your salesperson how you intend to use your new mountain bike, and how much you are willing to spend．Your salesperson will show you a selection of models and brands accordingly．He or she will also help you determine the right size of mountain bike for you．Mountain bikes come in a dizzying array of brands, sizes and styles, and your salesperson will cut through the tangle for you．He or she will also help you determine the right size for you．You may ask more for salesperson without any sense of shyness
Take a test ride．
All good bike shops let customers take test rides．There's a good reason for this beyond "try-before-you-buy" salesmanship．Since you already know your price range, and since your salesperson has already helped you find the right size, you now have to determine which brand rides the best to you．They want you to be happy with your purchase．They want you to ride your new mountain bike．So ride them．From more than one bike shop．One brand will feel too upright to you．Another will feel too long．Another too short．And finally, after only a few test rides （or many）, the right mountain bike will choose you

After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll （死亡人数） could have been much worse．More than 60 people died in this earthquake．By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25,000 victims．
Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a．m．on a holiday, when traffic was light on the city's highways．In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes．
Despite the good news, civil engineers aren't resting on their successes．Pinned to their drawing boards are blueprints （蓝图） for improved quake-resistant buildings．The new designs should offer even greater security to cities where earthquakes often take place．
In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood that bend without breaking．Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations．The most recent designs give buildings brains as well as concrete and steel supports．Called smart buildings, the structures respond like living organisms to an earthquake's vibrations．When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction．
The new smart structures could be very expensive to build．However, they would save many lives and would be less likely to be damaged during earthquakes．
1.One reason why the loss of lives in the Los Angeles earthquake was comparatively low is that __________．
A．new computers had been installed in the buildings
B．it occurred in the residential areas rather．than on the highways
C．large numbers of Los Angeles residents had gone for a holiday
D．improvements had been made in the construction of buildings and highways
2.The smart buildings discussed in the passage __________．
A．would cause serious financial problems
B．would be worthwhile though costly
C．would increase the complexity of architectural design
D．can reduce the ground vibrations caused by earthquakes
3.It can be inferred from the passage that in minimizing the damage caused by earthquakes attention should be focused on __________．
A．the increasing use of robber and steel in capital construction
B．the development of flexible building materials
C．the reduction of the impact of ground vibrations
D．early forecasts of earthquakes
4.The author's main purpose in writing the passage is to __________．
A．compare the consequences of the earthquakes that occurred in the U．S．
B．encourage civil engineers to make more extensive use of computers
C．outline the history of the development of quake-resistant building materials
D．report new developments in constructing quake- resistant buildings
