（1）图（甲）是一个多量程多用电表的简化电路图，测量电流、电压和电阻各有两个量程，当转换开关S旋到位置3时，可用来测量______（选填“电阻”、“电压”或“电流”）；当S旋到位置______时，可用来测量电流，其中S旋到位置______时量程较大
（2）用多用电表测量小电珠（4.8V1.4W）的电阻，应选择多用电表电阻挡的倍率______（选填“×1”、“×10”或“×100”）；调零后，将表笔分别与小电珠的两端连接，示数如图（乙），则测量结果为______Ω．
（1）当转换开关S旋到位置3时，内部电源被接通，构成欧姆表，可测量电阻．
当S旋到位置 1、2时，电流表与电阻并联，并联电阻起分流作用，可用来测量电流．
S旋到位置1时，并联电阻阻值较小，则分流较大，故S旋到位置1时，电流表量程较大．
（2）小电珠（4.8V，1.4W），所以小电珠电阻大约是11Ω，
粗测小电珠的电阻，应选择多用电表×1倍率的电阻档，结果为12Ω
故答案为：（1）电阻；1或2；1．（2）×1；12．
Cleanse, tone and moisturize: three words that everyone should keep in mind when going through their daily routines. As a society, we decide what are important habits to keep up with, such as taking care of your skin. It takes a good five minutes every morning and night to properly care for your skin, but most men and women believe that they do not have time in their busy schedule to do so. Having good skin boosts（增加）sef-confidence and improve overall health and attitude. Cleansing the face is important for women who wear make-up because it clears the face from exposure to free radicals（自由基） in the air. Toning your face is important to balance your skin’s PH level ( which needs to be between 4.5 and 5.5 ) and also to remove the impurities from water, which is full of lead. Finally, moisturizing your face hydrates（增湿）the skin. In this day and age there are more issues with free radicals that damage your skin than ever before. Smog, UVA/ UVB damage, smoke, alcohol, and more are all negative contributing factors to damaging the aging of your skin. The global community has advanced the environment into a high percentage of free radical, but we also now have the technology for the best skin care. The issue with skin care is most people feel that you only need to take action if you have a serious skin condition, such as acne(粉刺). But no matter what age and what condition your skin is in, you should actively do something to maintain it. Most skin care products today are all-natural; many of them advertise being 100 percent vegan（素食）. Ingredients（成分）that are natural for anti-aging are : DMAE, alpha lapoic acid, antioxidants, collagen booster, SPF and many more. All of these ingredients help prevent aging and sun damage while regenerating new skin cells. Aging appears fastest on your face, neck, and back of the hands and feet, which means you must apply skin care products to all areas. People need to take care of their skin, whether they have a skin condition or not. If one wants to age gracefully, one must put forth the effort on their skin.
