In the interest of lightness of weight, everything you carry in your pack should serve as many purposes as possible. Clothing and sleeping gear constitute the greatest amount of bulk in your pack and probably the most weight. Thus, you should choose clothes and sleeping gear with a great deal of versatility in mind. Get the maximum use from the various items of clothing and sleeping gear and combinations of them.
For example, instead of two pairs of long pants, carry one pair of long pants and a pair of shorts. You can wear the shorts alone, or the long pants alone, or both at the same time.
The same with shirts. Instead of one heavy shirt, carry two medium-weight shirts-one with long sleeves, one with short sleeves. Carry two light-weight wool sweaters instead of a heavy sweater or jacket. Even better, carry a light-weight wool sweater and a wind shell. This gives you three possibilities: sweater alone, shell alone, sweater and shell together. Additionally, you will be warmer in several layers of clothing than in one layer of heavy clothing. The shell, light sweater, and two shirts will keep you warmer than one shirt and a heavy sweater or jacket.
This same layering principle applies when you sleep. Better to have a light-weight sleeping bag and wear several layers of clothing than to have a heavy-duty, low-temperature sleeping bag.
Of course, different people sleep warm or cold, depending upon their body metabolism. And those needs should obviously be considered in the assembly of clothes they carry.
Should you find yourself in a freak situation such as zero temperature, when you start out in weather that should not have dropped below 30 degrees, there are a number of things you can do to improve the warmth of your sleep.
(1) You can sleep inside a tent, of course. This increases the temperature by 5 to 10 degrees and it cuts the wind chill factor substantially. (2) Camp out of the wind if possible. This cuts down the wind chill factor. (3) Place your sleeping bags close together. This retains the heat for all of you. (4) Camp on the side of a hill instead of on the valley floor, especially on clear nights. Warmer air lifts up and off the valley floor on clear nights. There can be as much as 15 degrees difference between the temperature on the side of the hill and that on the valley floor.
All of the following aspects of backpacking are discussed in the passage except ______.
选项
A、wearing several layers of clothing
B、getting maximum use from your pack material
C、improving the warmth of your sleep
D、forecasting the weather
答案
D
解析
本题使用排除法即可解决。文章第五段:...you will be warmer in several layers of clothing than in one layer of heavy clothing.(穿几层衣服比穿一层厚衣服暖和。)证明A项所述正确。文章第一段最后一句话:Get the maximum use from the various items of clothing and sleeping gear and combinations of them.又证实了B项的正确性。C项表述正确的依据在第六段; The same layering principle applies when you sleep.而运用同一原则的目的是为了能更好地取暖。尽管文章中确实谈论到御寒的方法,但是却没有预报天气,因此D项为不正确的陈述,符合题意,为本题答案。
