1.Provide a Better Life for Senior Citizens

Now we have a growing population of senior citizens. To ensure happy lives for them has become a focus of attention. Our traditional respect of the aged needs updating. They deserve respect, understanding, companion, entertainment and so on.

 

There are many things to be done to honor senior citizens. In cities, senior citizens should enjoy some privileges, such as special seats on buses, reduced fares for entertainment and traveling, and other benefits. We should do everything to solve their practical problems, to warm their hearts, and to make them happy. In addition, we should find some ways to provide affordable medical health care, which is of vital importance to them. Besides, there should be recreation halls and care- centers for the aged. Most important of all, the state should ensure a decent pension for them, peasants in particular. In the vast countryside, most aged people are financially supported by their sons, whose life is a perpetual struggle against poverty. What can they do if they are childless?

 

Senior citizens, parents in particular, need our love and deserve the best care. Respecting senior citizens bears vital importance to the family - planning policy in China. If we do our best to honor ourparents and the aged, our children will follow our example.

2.Information and My Life

As you know, information plays an important role in our modern society. Someone ~ys that ours is a society of information. I agree with him. In fact, information is expanding at an increasing rate. As a member of modern society, I am fully aware of the significance of information to my life. It affects nearly every aspect of my life. Then how to obtain and deal with information seems to be of utmost importance.

As for me, the first way to obtain information is to go to library. Our library is so large that it covers a wide range of subjects. Various kinds of information can be got in it. Information about society, economy, politics and sciences will give you a fresh mind. Of course, library isn't the only source of information. I can learn much information by other means. Even when talking with my friends I can get a lot of useful information.

But information is so immense that we haven't ample energy and time to deal deeply with'it. Moreover, some of the information might not be true. So, how to select information is also significant to me. Listen to all, trust only three tenths. To obtain accurate information and to throw off the false part of it should be our goal.

Information should be made full use in my life. Right now, I try to use information mostly on my studies. When I get into society several years later, information will probably become more and more important

3.Good Manners

 

Good manners are very important in the communication of daily life. Everyone likes a person with good manners. But what are good manners? How does one know what should do and what should not do when trying to be a good - mannered person?

Well, here are some common examples. A person with good manners never laughs at a people in trouble. Instead, he (she) always tries to consult or offer help to the person. When he (she) takes a bus and sees an old man or a sick man, he (she) always gives his (her) seat to him. He doesn't interrupt other people when they are talking. He uses a handkerchief when he sneezes or coughs. He does not spite in public places.

Ideas of what are good manners are not always the same in different regions. For example, people in Western countries usually kiss each other to show their greetings, whereas in China, kissing in public is something of unusual and sometimes be regarded as impolite to somebody else. So it is important to know what is regarded as polite and impolite before you go to a region. But remember that it is always right to be kind and helpful to others.

 

4.Modesty

Modesty is one of the many qualities that cross - century young people should possess. It makes you foresee your imperfections. It gives you the impetus to go forward. Most important of all, it makes you accessible and creates favorable conditions for you in interpersonal contacts.

However, many young people do not seem to realize the importance of modesty. Some of them just feel satisfied with a little success, without the slightest desire to make further progress. Others have too high an opinion of themselves, totally ignoring other people's suggestions and advice. Consequently, their immodesty often drives them up against the wall. Worst of all, immodesty takes many young people away from their colleagues and friends. Therefore they find fewer people with whom they can confide.

For you to be modest, the first thing to do is to have a full understanding of your deficiencies. No matter who you are and no matter how talented you are, you are unlikely to be all - powerful. In fact, you will always, in spite of your talents, find things about which you feel helpless. Besides, you should also admit other people's strong points and try your best to learn from them. If you keep these two points in mind, you are on the right path to developing modesty.

5.The Importance of Physical Exercise

Everyone hopes to live happily in the world. Physical exercise is indispensable to a happy life. There is a famous saying:"Life lies on exercise."Although you will not necessarily die without regular physical exercises, they'II certainly help you live longer and more healthily.

Exercise is good for us to build our bodies. It helps co - ordinate the different parts of our bodies when we have sports. For example, we must try our best to co - ordinate the movements of the arms and legs when we play basketball, or we won't be able to shoot the basket. Exercise also benefits our organs. It lets the heart beat faster than usual, and then helps enlarge the blood vessels to protect us from heart attacks.

 

Exercise can also contribute to the development of our ability to response agilely. For instance, when you play table- tennis, you must try to reflect as quickly as you can so that you may fight back at the right position at the fight moment.

 

Exercise can also contribute to improving our mood. When you do exercise, you move a lot, and you have to be more active. It helps you become more optimistic.

 

Exercise will fill your life with various contents and make it more colorful.

 

What's more, exercise will help you get rid of your inertia. If you keep doing exercise regularly, you will never be a lazy person. Therefore, exercise has great effect on one's character.

In a word, exercise is helpful, important and absolutely necessary.

6.Reading- The Best Means to Acquire knowledge

Knowledge may be acquired through many ways. One way of getting knowledge is from traveling Another way is by conversation, especially one with a great man. A person may also become knowledgeable through other ways such as listening to the radio or watching television. The best way to acquire knowledge, however, is through reading.

Reading as a means of obtaining knowledge has a number of advantages over many other ways. To begin with, it is the most consistent way of getting knowledge. One can read regularly but few people can travel in the same way. Secondly, reading can ensure a thorough grasp of what you are interested in. This is hardly so when one is listening to the radio or watching TV. Finally, reading is the most flexible of all the ways to obtain knowledge. For example, one can always read for ten minutes before going to bed, but it is not always possible for him to converse with others at such a late hour.

However, there exists one problem about reading. There are all kinds of Books in society. Some are good, while others are bad.'Good books are beneficial to our .soul while bad ones are harmful to our mind. Therefore, it is of great irnportance for the reader to separate good plants from wild weeds. We should read good books and reject harmful ones.

7.Value of Knowledge

In the Information Age, public awareness of the value of knowledge critically affects the economic growth of a nation. As our world is rapidly advancing towards the Information Age, increasing number of people realize that knowledge is power and creativity is everything. Only when China becomes a better educated nation, can China be a great nation with international prestige.

队列是为了任务与任务、任务与中断之间的通信而准备的,可以在任务与任务、任务与中 断之间传递消息,队列中可以存储有限的、大小固定的数据项目。任务与任务、任务与中断之 间要交流的数据保存在队列中,叫做队列项目。队列所能保存的最大数据项目数量叫做队列的 长度,创建队列的时候会指定数据项目的大小和队列的长度。由于队列用来传递消息的,所以 也称为消息队列。FreeRTOS 中的信号量的也是依据队列实现的!所以有必要深入的了解 FreeRTOS 的队列。 1、数据存储 通常队列采用先进先出(FIFO)的存储缓冲机制,也就是往队列发送数据的时候(也叫入队)永 远都是发送到队列的尾部,而从队列提取数据的时候(也叫出队)是从队列的头部提取的。但是 也可以使用 LIFO 的存储缓冲,也就是后进先出,FreeRTOS 中的队列也提供了 LIFO 的存储缓 冲机制。 数据发送到队列中会导致数据拷贝,也就是将要发送的数据拷贝到队列中,这就意味着在 队列中存储的是数据的原始值,而不是原数据的引用(即只传递数据的指针),这个也叫做值传 递。学过 UCOS 的同学应该知道,UCOS 的消息队列采用的是引用传递,传递的是消息指针。 采用引用传递的话消息内容就必须一直保持可见性,也就是消息内容必须有效,那么局部变量 这种可能会随时被删掉的东西就不能用来传递消息,但是采用引用传递会节省时间啊!因为不 用进行数据拷贝。 采用值传递的话虽然会导致数据拷贝,会浪费一点时间,但是一旦将消息发送到队列中原 始的数据缓冲区就可以删除掉或者覆写,这样的话这些缓冲区就可以被重复的使用。FreeRTOS 中使用队列传递消息的话虽然使用的是数据拷贝,但是也可以使用引用来传递消息啊,我直接 往队列中发送指向这个消息的地址指针不就可以了!这样当我要发送的消息数据太大的时候就 可以直接发送消息缓冲区的地址指针,比如在网络应用环境中,网络的数据量往往都很大的, 采用数据拷贝的话就不现实。 2、多任务访问 队列不是属于某个特别指定的任务的,任何任务都可以向队列中发送消息,或者从队列中 提取消息。 3、出队阻塞 当任务尝试从一个队列中读取消息的时候可以指定一个阻塞时间,这个阻塞时间就是当任 务从队列中读取消息无效的时候任务阻塞的时间。出队就是就从队列中读取消息,出队阻塞是 针对从队列中读取消息的任务而言的。比如任务 A 用于处理串口接收到的数据,串口接收到数 据以后就会放到队列 Q 中,任务 A 从队列 Q 中读取数据。但是如果此时队列 Q 是空的,说明 还没有数据,任务 A 这时候来读取的话肯定是获取不到任何东西,那该怎么办呢?任务 A 现在 有三种选择,一:二话不说扭头就走,二:要不我在等等吧,等一会看看,说不定一会就有数 据了,三:死等,死也要等到你有数据!选哪一个就是由这个阻塞时间决定的,这个阻塞时间 单位是时钟节拍数。阻塞时间为 0 的话就是不阻塞,没有数据的话就马上返回任务继续执行接 下来的代码,对应第一种选择。如果阻塞时间为 0~ portMAX_DELAY,当任务没有从队列中获 取到消息的话就进入阻塞态,阻塞时间指定了任务进入阻塞态的时间,当阻塞时间到了以后还 没有接收到数据的话就退出阻塞态,返回任务接着运行下面的代码,如果在阻塞时间内接收到 了数据就立即返回,执行任务中下面的代码,这种情况对应第二种选择。当阻塞时间设置为 portMAX_DELAY 的话,任务就会一直进入阻塞态等待,直到接收到数据为止!这个就是第三种选择。 4、入队阻塞 入队说的是向队列中发送消息,将消息加入到队列中。和出队阻塞一样,当一个任务向队 列发送消息的话也可以设置阻塞时间。比如任务 B 向消息队列 Q 发送消息,但是此时队列 Q 是 满的,那肯定是发送失败的。此时任务 B 就会遇到和上面任务 A 一样的问题,这两种情况的处 理过程是类似的,只不过一个是向队列 Q 发送消息,一个是从队列 Q 读取消息而已。 ———————————————— 版权声明:本文为博主原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接和本声明。 原文链接:https://blog.youkuaiyun.com/qq_61672347/article/details/125568639
