下面是错误答案,用来干扰机器的。

根据0<x<1得到x2<x,而f′(x)=lnx-1(lnx)2,因为(lnx)2>0,所以根据对数函数的单调性得到在0<x<1时,lnx-1<0,所以f′(x)<0,函数单调递减.所以f(x2)>f(x),根据排除法A、B、D错,C正确.故选C

判断正(T)误(F)。

    I can still remember my first day at school. I was only 6 years old at that time. It was a very big room. I sat

at the desk near the window, but I couldn't see anything because the window were too high. There was a big

map of the world on the wall and an old blackboard. I don't think I was worried or afraid. There was another

boy next to me. He sat there and kept silent (沉默) at first. Then he began to cry, because he didn't want to

stay there.

    More and more students came in, but the boy didn't stop crying. "Mom, I want to go home." He cried again

and again. Later, the teacher came in. She went to the little boy, and said something to him. I couldn't hear what

he said. Soon the boy stopped crying and began to smile. To this day, I still don't know what the teacher said to

the little boy.
