02练习题练习题(二)Ⅰ问答题1. 什么是进程?为什么要引入进程概念?进程都有哪些特征?答:(1)进程是一个可并发执行的具有独立功能的程序关于某个数据集合的一次执行过程,也是操作系统进行资源分配和调度的独立单位。

(2)在多道程序环境下,程序的并发执行代替了程序的顺序执行,资源共享和竞争又导致并发程序之间的相互制约性,使得系统中运行的程序是处于走走停停的状态之中,当一个程序获得处理机后向前推进,当它需要某种资源而未得到时只好停下来,以后得到所申请资源时再继续前进。

基于“程序”这个静态概念已不能完整、有效地描述并发程序在内存中的运行状态。

因此,为了实现程序在多道程序环境下的并发执行,必须引入一个能确切描述并反映并发过程的新概念—进程,以便从变化的角度动态地研究程序的执行。

(3)进程的特征:动态性、并发性、独立性、异步性、结构性。

2. 叙述进程和程序的关系?答:进程与程序的联系是:(1)进程包括一个程序;(2)进程存在的目的就是执行这个程序。

进程与程序的区别是:(1)进程是动态的概念,程序是静态的概念。

程序是指令代码的有序集合;进程是程序的一次执行过程,它能动态的被创建、调度执行,执行后消亡。

(2)进程是暂时的,程序是永久的。

进程是一个程序执行状态变化的过程,程序是可长久保存。

(3)进程是由程序、数据和进程控制块组成。

程序是由若干行代码组成。

(4)通过多次执行,一个程序可对应多个进程;通过调用关系,一个进程可包括多个程序。

(5)进程能够独立运行,可以为其独立分配资源,独立接受调度的单位,而程序不能在多道程序设计环境下运行。

3. 叙述进程的并发性和制约性。

答:并发性是进程的重要特征。

即多道程序中多个进程同时向前推进的过程,每个进程总是与其它进程并发地执行的。

进程的制约性是指一个进程的运行受到另一进程的制约(直接制约和间接制约)。

如进程在运行过程中,有的进程可能正在等待另一进程的计算结果而无法运行,或者进程所需的资源被别的进程占有而无法运行。

自考00015英语(二)练习题 02

英语(二)练习二(Unit 2)一、阅读选择1、Good Communication for Making FriendsAs a communication skills trainer, I've met a wide range of people. Some people have trouble associating with others and have difficulty making friends. So I would like to discuss two key points to making good friends. The first is to show respect and love for your friends through your words. Try to say things to others that would feel good to you if you heard them. For example, say things like, "Thanks for the great time" and "It was really nice to get to know you."If you are not good at speaking, then smiling and using body language to express your sincerity is also an effective way to communicate. Additionally, I recommend that when you meet someone new send them an e-mail or letter before the day is over to express how nice it was to meet them.The goal of good communication is to reach another person's heart and form a comfortable relationship. It is, therefore, based the premise that you get rid of your worries and become a bright and positive person. When there is static noise over the phone line, you can't hear the other person clearly, right? In the same way, when your mind is full of worries and you try to communicate with another person, you cannot give or receive messages accurately. For example, let's say you are still tied to a past wound of being betrayed by a friend and feeling hurts .Even if you meet someone new and he or she tells you, "Let's be good friends," you may not be able to accept it because you will hear a negative inner voice saying something like "I might be betrayed again" or "the person might have a hidden agenda."With this worry in your mind, you will not be able to make friends.If you can be refreshed and get rid of your worries, you should be able to sense others' thoughts and feelings without prejudice and build a relationship of trust. If you really can't let go of your painful past experience, then try to change your perspective on the experience.For example, try to think that it was a necessary lesson for you to understand others' pain. If you can think of the positive intention behind the event, then you will be able to view the experience favourably and feel better.<1> 、The main topic of the passage is________. ( )A、how to communicate with othersB、how to refresh yourselfC、how to forget the past unhappinessD、how to show respect and love for your friends<2> 、The effective way to communicate includes________.( )A、showing respect and love for friends with wordsB、smiling and using body languageC、sending an e-mail or letterD、All of the above<3> 、The effective way to communicate includes________.( )A、showing respect and love for friends with wordsB、smiling and using body languageC、sending an e-mail or letterD、All of the above<4> 、Which of the following statements is NOT true according to the passage? ()A、Body language is as effective as saying things that will make friends feel better.B、If you distrust others, then it's difficult for you to make new friends.C、The writer conducted a research on how people communicate with their friends.D、Minds full of worries will do great harm to interpersonal relationship<5> 、The example in paragraph 2 is intended to show that________. ( )A、the goal of good communication is to reach another person's heartB、the goal of good communication is to form a comfortable relationshipC、good communication is based on the premise that you get rid of your worries and become a bright and positive personD、it does take time for someone to forget all about the painful past<6> 、In the sentence "the person might have a hidden agenda" (para.2) ,the word "agenda" means________. ( )A、relationshipB、planC、worryD、past二、概况段落大意和补全句子1、Overcoming Difficulties① Life is full of difficulties and obstacles, from birth to death. At times, Life seems like a hurdle race. We are sure of encountering hurdles, but almost always we are taken by surprise. It is necessary to accept that life in general is full of difficulties and adversities. This recognition is the first step. When faced with problems, we often feel, "I am the only one having such problems" Or, we tend to exaggerate our problems and regard them as most complex, most painful,and as an extreme case. But if we look around us, we find people in much worse conditions. As St. Augustine said, "I cried for boots, till I saw a man who had no legs."② When faced with difficulties, we either complain or seek to dodge them. We behave like as ostrich in the desert. It is said that when there is a storm in the desert, the ostrich buries his head in the sand-hoping that the storm will go away if he ignores it-and finally gets buried under a heap of sand and dies. Some of us choose to pretend that the problems do not exist. We fail to realize that confronting and solving the problem-no painful the process-makes us grow.③ Accept the woes of birth. It has many implied meanings. First, it means "accepting," i.e., being able to say that it is "my" problem and it is up to me to solve it. Many times we find ourselves putting the blame on others-parents, society or the circumstances of life. Nothing happens by chance, but all is the result of our past actions. There are times when what is needed is patience. We seek to come out of an unpleasant situation quickly. We must understand that if the cause had been operating for a long time, the effect also would last long-as even when the gas has been turned off, the burner remains hot for a long time. Similarly, we expect quick results; having put in the effort, we must be willing to wait. Patient acceptance of what is due to us makes us makes us take a step further in our development.④ Once we have learnt to deal with a difficulty, the next time we encounter it, it ceases to be a difficulty. But, more often than not the cause of the problem is internal, i.e., within us, and often, it calls for a change. Often the difficulty is solved when we are willing to change—our way of thinking, our feelings, our likes and dislikes—and ready to adapt or adjust ourselves to a problematic situation or a person in life. We must realize that realize that change is inevitable, and always be mentally prepared for it.⑤ Not all life's problems are such that they need to be dealt with all at once. Sometimes it is possible to take a step and wait for a long time. For instance, if the tap is leaking then we need to call a plumber as soon as we can. But having called him and having found that he can come only the following morning, we should wait patiently for the next 24 hours. In this period, people can get very anxious and go on talking about it to others. There are many such problems in life.16. Paragraph①___________17. Paragraph②___________18. Paragraph③___________19. Paragraph④___________20. Paragraph⑤___________A. There are implied meanings about the accepting the woes of birth.B. Diligence is also very important in solving problems.C.

This symbolizesThose obstacles in life that we struggle to get over, but we always manage to do so. You can look at that hurdle in two ways: "I c an’t make it over, I’m too tired" or "I am one more hurdle closer to finishing this race". This is an example of taking a negative situation and seeing something positive in it.The next part of the race is every hurdle between the first and last one. __27__ This happens a lot in life too. There may be a situation that arises where you feel as though you can’t make it and all you can think about is giving up. You may fall over that "hurdle" or struggle getting over it, but somehow you find it in yourself to jump over it and move on with the race.Next is that last 100m of the race. You feel as though you just want to say, "No I can't do this." __28__Now lastly is the last hurdle. This hurdle is the toughest out of all of them. In life we find ourselves falling and falling, and maybe getting too lost in our problems that we fell like have been though enough and there’s no hope. __29__ It's one step close to the end of the race.Once you finish, you look back on it and you realize that you made it not by leaping, but step by step. "Yard by yard, life is very hard. But inch by inch, life can be a cinch."___30___A. This hurdle the easiest to get over because you are not worn out from running.B. Again, you must find it in yourself that you can do it, and you must finish the race stronger thanwhen you had started it.C. All it takes is one step at a time, one hurdle at a time.D. That last hurdle symbolizes these situations.E. These hurdles get tougher and tougher and you may feel as though you can’t go onF.

1、分析下面程序的运行结果,理解工作原理。

#include "stdio.h"
int main(int argc, char* argv[])
{
char c;
while((c=getchar())!='x')
{
printf("%c",c);
}
return 0;
}
2、请说出使用const和define定义常量,在语法上和含义上有什么不同,并编程举例说明。

3、请说出字符常量和字符串常量的区别,并使用sizeof计算他们所占用的字节数。

并使用该运算符计算几种基本的数据类型和对应变量所占用的字节数,并编程说明。

4、从键盘输入一些字符(回车时候结束),将其中的小写字母变为大写字母然后进行输出。

5、从键盘输入一个表示年份的数(1000-4000),判断该年是否闰年,并输出对应提示信息(闰年的计算算法是能被4整除,不能被100整除,则是闰年,结束;或能被400整除,则是闰年,结束)
6、(拔高题)求任意2个日期之间相差的天数。
