There are differences between western culture and Chinese culture. We can see differences when we pay attention to the way words are used. Let’s look at the words about animals and plants. Most expressions in Chinese is about the dog, for example, “a homeless dog”, “a mad dog”, “a running dog” and “a dog catching a mouse”, have negative(消极) meanings. But in western countries, dogs are thought to be honest and good friends of humans. In English, people use the dog to describe positive(积极的) actions. For example, “you are a lucky dog” means you are a lucky person. And “every dog has its day” means each person has good luck sometimes. To describe a person’s serious illness, they say “sick as a dog”. The word “dog—tired” means very tired. However, Chinese love cats very much. But in western culture, “cat” is often used to describe a woman who is cruel(冷酷的). There are many other examples of how “cat” is used differently as well.

The rose is regarded as a symbol of love in both China and some western countries. People think the rose stands for love, peace, courage and friendship. And the rose is the national flower of England, America and many other countries.

The words about plants and animals are used in positive or negative ways in different cultures. We can learn about many differences in cultures by comparing how some words are used.

有两个进程(编号分别为0和1)需要访问同一个共享资源。为了解决竞争条件(race condition)的问题，需要实现一种互斥机制，使得在任何时刻只能有一个进程访问该共享资源。以下[C程序代码2]给出了一种实现方法。

[C程序代码2]

int flag[2]; /*flaq数组, 初始化为FALSE*/
Enter_Critical_Section (int my_task_id, int other_task_id)
while (flag [other_task_id]==TRUE); /*空循环语句*/
flag[my_task_id]=TRUE;

Exit_Critical_Section (int my_task_id, int other_task_id)
flag[my_task id]=FALSE;

当一个进程要访问临界资源时，就可以调用[C程序代码2]给出的这两个函数。[C程序代码3]给出了进程0的一个例子。

[C程序代码3]

Enter_Critical_Section(0,1) ;
…使用这个资源…
Exit_Critical_Section (0,1) ;
…做其他的事情…

[C程序代码2]所示的方法______实现共享资源的互斥访问。
A．能够 B．不能
