阅读以下说明、C函数和问题,将解答填入答题纸的对应栏内。

【说明】二叉查找树又称为二叉排序树,它或者是一棵空树,或者是具有如下性质的二叉树:?若它的左子树非空,则其左子树上所有结点的键值均小于根结点的键值;?若它的右子树非空,则其右子树上所有结点的键值均大于根结点的键值;?左、右子树本身就是二叉查找树。设二叉查找树采用二叉链表存储结构,链表结点类型定义如下:

函数find_key(root,key)的功能是用递归方式在给定的二叉查找树(root指向根结点)中查找键值为key的结点并返回结点的指针;若找不到,则返回空指针。【C函数】

若某二叉查找树中有n个结点,则查找一个给定关键字时,需要比较的结点个数取决于__(5)__。

The consumer(消费者) plays a very important role in the global efforts to reduce C02 emissions(排放). Households use one third of the final energy and produce around two thirds of city waste in the European Union. Besides,housing, food,and private transport make up almost 80% of environmental pressures. Therefore there’s no doubt that consumers can make a real difference in fighting climate change.

To direct consumers towards more environmentally-friendly decisions,we need clear and simple instructions to guide consumption behavior. Actually, two thirds of consumers find it hard to figure out which products are better for the environment, for 58% Europeans think that many businesses just pretend to be green so as to charge higher prices. Thus industry should work harder to give consumers more information about the carbon footprint of their product. For example, inform customers of products made from materials that are recycled,renewable, and/or less carbon-intensive.

People prefer high-quality products that will last long and won’t go out of style, though they might sometimes cost more, especially in time of crisis. Firms that make durable(持久耐用的) or recyclable products cause people to behave more responsibly, which may help put an end to our “throw-way” culture.

However, it is not enough to remind people of green products. It’s more important to direct people to follow a practical lifestyle model. Regulations alone cannot achieve this purpose. We call for good business communities to create a loyal group of “sustainable(可持续的) consumers”.
