BETWEEN(45,30,48)的运算结果是______。

答案

参考答案:.T.

解析: 函数BETWEEN()是值域测试函数,它的格式是c BETWEEN(表达式T>,<表达式L>,<表达式H>),功能是判断一个表达式的值是否介于另外两个表达式的值之间。当<表达式9>值大于等于(表达式L>且小于<表达式 H>时,函数值为逻辑真(.T.),否则函数值为逻辑假(.F.)。如果。(表达式L>或<表达式H>有一个是NULL值,那么函数值也是NULL值。
题干中的<表达式T>为40,<表达式L>为30,<表达式 H>为48,因为40介于30与48之间,所以函数返回逻辑真 (.T.)。

We could all see the Murray Uiver slowly moving back, but now all the water was gone . I couldn’t believe that the Murray had dried up, not one drop of water left.

One morning I went down to the river to try and catch some fish when I saw my boat high and dry (搁浅) on the bank . I rushed down the river and saw all mud—no water . The fish were just lying there, dying . I looked up to see if my friend was there . There was the nest but no eagle(鹰). I called out to her with my special whistle which I made out of steel.

Suddenly a big shadow came over to me and the eagle landed in her nest and gave her young the food she was out getting while I whistled. But then I suddenly noticed she was getting thinner and had a bit of sheep’s wool in the side of her talon(利爪). It was deadly quiet by the river bank , except for some sound from my dog. And also I couldn’t see one native animal or bird.

When I walked inside the kitchen. Mum and Dad had sad looks on their faces. “It’s time for us to move ,Son, because the river can no longer provide for(养活)us,” said Dad . I ran out of the kitchen door with tears in my eyes , and down to the river bank, to my favorite spot. I said goodbye to my eagle , crying.

When it was time to go , I saw my eagle fly up into the air with her chicks in her talons , going away to try and find another home ,just like us.
