2.Tips for Cycle TripsCycling has many advantages as a form of travel,as it is the fastest way to travel by human power,and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation.
Distance
On level terrain(地形),without a headwind,a cyclist of average fitness on a touringbike can comfortably cover 60-120km a day.Distances of up to 250km a day are possible,but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many,80-100km a day will be the most suitable distance to aim for,as it will give a sense of achievement and also leave plenty of time for meals and activities.
Geography
The gradient(坡度)of the trip will reduce your range.A basic rule is that for every 100metres of altitude you climb,you should add an extra 15minutes to your journey time.In hilly or mountainous areas,the easiest routes for cycling are downstream along major rivers,as overall they will be downhill.A long,roundabout route along a river will usually be easier than a short,direct route over a hill or mountain pass.However,it is worth bearing in mind that the most scenic routes often come from hilly terrain.
Eat
Food choice depends largely on where you are,so see the respective sections for more information about foods.As you will be working hard,it's important to get enough energy in your food.On long trips away from major towns-there may be little quality food available,so be prepared to live on candy bars,prepared meat products and the like if the need arises.
Sleep
While you can take a tent with you,many hotels and especially campsites can accommodate cyclists.However,there are also some hotels that may be less used to accommodating cyclists.If you are exploring an unfamiliar word,asking about the accommodation spares you the search for a new place to stay after a long exhausting day of travel.

分析 本文介紹騎車旅行,旅行距離,地理位置及過程中的飲食和睡覺的注意事項.
解答 21.B 細節(jié)理解題.根據(jù)第二段提到On level terrain(地形),without a headwind,a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day.在一定的條件下,沒有逆風的情況下,一個健康的騎車人的行程每天應在60到120之間,故選B項.
22.C 推理判斷題.根據(jù)第三段提到A long,roundabout route along a river will usually be easier than a short,direct route over a hill or mountain pass.However,it is worth bearing in mind that the most scenic routes often come from hilly terrain繞河的路線比繞山的路線簡單,但繞山的風景是漂亮的,故選C項.
23.D 推理判斷題.本文在講到騎車旅行距離,地理位置,食物及睡覺的注意事宜,故在旅行雜志看到,所以選D項.
點評 考察學生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
