1. A.
   
2. B.
   
3. C.
   
4. D.
   

Answer 1

B
分析：求一個(gè)數(shù)的倒數(shù)，即用1除以這個(gè)數(shù)；
絕對(duì)值的性質(zhì)：一個(gè)正數(shù)的絕對(duì)值是它本身；一個(gè)負(fù)數(shù)的絕對(duì)值是它的相反數(shù)；0的絕對(duì)值是0．
解答：的倒數(shù)是-，-的絕對(duì)值是．
故選B．
點(diǎn)評(píng)：此題考查了倒數(shù)和絕對(duì)值的性質(zhì)，要求掌握倒數(shù)和絕對(duì)值的性質(zhì)及其定義，并能熟練運(yùn)用到實(shí)際當(dāng)中．
