One day, my sister, who has been pregnant for six months, caught a bad cold. She wanted to take medicine for her cold but she wondered whether the medicine will do harm to the baby. She turned on the computer, went online and googled or searched for information on the safety of the cold medicine. After that, she made a right decision.
The impact that computer has on our daily life is undeniable. There is a growing awareness of both the positive and negative influences that computers have brought to us. Some people might be right to think that computers have made life complex and stressful. From my point of view, those shortcomings can be neglected when the advantages of computers are mentioned.

According to a recent statistic on the internet, the number of single-child family occupies 75 percent of Chinese families, and undoubtedly has the tendency of increasing. It follows that parents or other adult relatives may likely pay more attention to their children, for the reason that the energy of parents has been saved a lot compared to those who own several children. Some people insist on making decisions for their children, considering that they are too young to judge. However, others believe that there is hardly any necessity to help so that children will cultivate the capability of analyzing important problems. From my perspective, I completely agree with the latter idea.

With the development of science and technology, more and more companies (including international companies and small companies) are founded, but there are not enough people to take these positions. So a large number of working opportunities are provided to people who are still teenager students. In some countries, some people think if teenagers do a job while they are still studying in school, it may have a bad impact on their grade. Others consider that teenagers should have jobs while they are still students. As far as I am concerned, I agree with the latter. Because teenagers can learn amount of useful experience through working and they think through the job they will acquire some knowledge of how to get a good relationship with others.

It is not rare to see many students dozing off or doing other things while the professor is trying his best explaining a theory. Most people claim that this phenomenon results from the severe school attendance rule and suggest that students should be given more right to decide which class to attend according to their own interest and their judgment of the value of the class. This idea is strongly opposed by numerous people who hold the opinion that it is the fault of the students that leads to the current problem. They stand on the ground that students do not really know what they are particularly suitable to make research on and what kind of class is remarkably valuable. Consequently they think highly of the rule that students should attend all the classes. As far as I am concerned, strict school attendance really benefits the students in not only acquiring knowledge but also their social skills.

Technology refers to skills, knowledge, and techniques that human beings use in their daily life and work. As everybody may find, technology develops day by day. How does the development of technology affect our life? Many people hold the opinion that it is due to the development of technology that human beings have access to the comfortable modern life. On the other hand, a number of people are always aware of all kinds of destructive influence of the technological development on us. As far as I am concerned, the development of technology does far more good than harm to people’s happiness.

I’m a great believer in luck, and I find the harder I work, the more I have of it.
                                           ——Thomas Jefferson
There is little doubt that if people want to be successful, hardworking is an essential element. While it is also
clear that luck plays an undeniable role in one’s realizing dreams. I completely agree with Thomas Jefferson and
believe that hard work, in most cases, helps people find and catch their luck and finally reach their life goals.

Just imagine if a student can not find a teacher to help him, what will happen? Some people believe that he can learn better by himself; however, each coin has two sides, others think that it is always better to have a teacher. I agree with the latter one. Teachers can help us to acquire amounts of knowledge easier than others who study alone, lead us to choose the right way of our life, and let us know how to be a good person.
