3、(2分)下列命题:①负数没有立方根;②一个实数的立方根不是正数就是负数;③一个正数或负数的立方根与这个数的符号一致;④如果一个数的立方根等于它本身,那么它一定是1或0.其中正确有()个.A. 1B. 2C. 3D. 4【答案】A【考点】立方根及开立方【解析】【解答】解:①负数没有立方根,错误;②一个实数的立方根不是正数就是负数或0,故原命题错误;③一个正数或负数的立方根与这个数的符号一致,正确;④如果一个数的立方根等于它本身,那么它一定是±1或0,故原命题错误;其中正确的是③,有1个;故答案为:A【分析】根据立方根的定义与性质,我们可知:1.正数、负数、0都有立方根;2.正数的立方根为正数,负数的立方根为负数;0的立方根仍为0;与0的立方根都为它本身。

We met some American students and they were carrying flowers for us in the usual American way of greeting travellers.‘Does anyone speak English?’ asked one of them.‘I do, but a little,’I replied in a low voice, speaking for the first time to a real American.‘How many people are there in your group?’ the boy continued.‘Eighty,’I answered and found a strange looking on his face. Luckily, I quickly realized my mistake as I always found English numbers difficult. ‘Eighteen,’ I corrected myself.For the next week, the American students showed us round their beautiful cities and I spent most of my time with the first one I spoke to at the station.
