The Role of Mobile Phone in People's Communication （人之间的沟通问题）
The popularity of smartphones has exerted great influence on the way people communicate, so much so that an increasing number of individuals contend that face-to-face communication is being replaced by texts and images on the mobile phone.
There are more than one angle to consider this phenomenon. On one hand, it is pleasantly acknowledged that smartphones shorten the distance between families and friends. Even people from different sides of the globe can share pictures, feelings and thoughts through various types of apps on the phone, thus building a long-distance connection. On the other hand, as the picture warns us, too much smartphone addiction interferes with people's real-life communication. Statistics show that over 70 percent of face-to-face communication consists of facial expressions and body language, which is why people should stay away from mobile phones when they have the chance to actually talk and communicate with others.
The Beauty of Knowledge（知识的美）
Praise of knowledge has never come to an end since ancient times. Apparently, knowledge is a treasure that everybody volunteers to possess and much of success could be attributed to it directly or indirectly.
As far as I am concerned, the beauty of knowledge can be explained in three aspects.
Firstly, knowledge is open to all human beings. People can learn whatever they wish in one way or another. Secondly, knowledge learnt can be reflected in one's later life, so that one knows how to savor the present moment in peaceful times and how to deal with problems in difficult times. Last but not least, one of the most prominent features of knowledge is that one carries it throughout his life. Even if one loses a large fortune, he will never be a beggar if he already knows how to make money.
To sum up, knowledge is of great importance in one's lifetime. It is advisable that one should learn the beauty of knowledge and enjoy the process of learning.
The Meaning and Purpose of Life（生活的意义）
Everyone may encounter a scene when he or she wonders what the meaning and purpose of life is. Answers to this question vary from person to person. As for me, I agree with the view that the meaning of life is to discover your gift and the purpose of life is to make the best of it.
On one hand, one's gift could be the source of his inner happiness, providing spiritual impetus and correct orientation. Take the world-renowned Chinese pianist Lang Lang as an example. His gift was noticed before he was 3 years old, which laid the foundation of his glorious life. On the other hand, proper use of talent helps people to realize their value in a positive way, thus making contribution to the society as a whole. For instance, Isaac Newton made a universally amazing discovery by digging into his gift and finding the Newton's law of gravitation.
In conclusion, let's search for our true gift and utilize it to the fullest to achieve a happy and valuable life.。
