若函数f（x）=x³+x²﹣2x﹣2的一个正数零点附近的函数值用二分法逐次计算，参考数据如下：f（1）=﹣2，f（1.5）=0.625；f（1.25）=﹣0.984，f（1.375）=﹣0.260；

f（1.438）=0.165，f（1.4065）=﹣0.052．

那么方程x³+x²﹣2x﹣2=0的一个近似根可以为（精确度为0.1）（　　）

央视《朗读者》第二期节目主持人的开场白：“草，在结它的种子；风，在摇它的叶子；我们站着，不说话，就十分美好。”在顾城的诗里，陪伴就是这样简单而美好。而在我们每一个人的生命里，会遇到各种各样的陪伴，比如说这会儿，你我之间是一段短暂的陪伴；比如说我们的学生时代，和我们的同学，那是几年的陪伴；还有一种陪伴，是生命里血脉注定一生的陪伴，那是我们和父母，和孩子之间的陪伴。在这个世界上没有一个人是孤岛，失去了陪伴，也失去了生存的意义，所以陪伴也是一种力量。

你的世界也处处有陪伴的倩影，你也有许多时候享受陪伴的美好，他人给予你的，你给予他人的。请你以“陪伴”为题，写一篇文章。

要求：①立意自定，感情真挚，不得抄袭；②除诗歌外，文体不限；③不少于600字；④文中不得出现真实的人名、校名。

A Smart Dog

    Rico is a dog who lives in Germany,____ When his owner says the name of a certain toy, Rico can find it. In fact, he seems to know the names of 200 toys!

    ____. They put his toys in a room and then told him to go in the room and find a certain toy. Since nobody was in the room with Rico, he had no help from anyone finding the right toy. The researchers did this test forty times. Rico found the right toy thirty-seven times!

    Then the researcher tried something else. They put seven of Rico's toys in the room and one new toy that Rico had never seen before.____ . This new toy had a name Rico had never heard before. Rico found the right toy seven out of ten times!

    Researchers cannot really say that Rico know words or languages.____They believed Rico can think about what he hears and thin about what he knows. In fact, Rico seems to thin and remember things as well as three-year-old child.

    From these tests, animal researchers know one thing for sure. Rico has given them a lot to think about.

A. Then they told Rico to go into the room and get the new toy.

B. However, these tests seem to show Rico is smart.

C. Some researchers in Germany wanted to test Rico.

D. His owner has trained him to find his toys.
