Dear Professor,

I am writing to express my interest in the research project you mentioned in class last week. As a student majoring in computer science, I am eager to participate in the project and contribute my knowledge and skills to the team.

I have some experience in programming and data analysis, and I believe that I can make a valuable contribution to the project. I am also willing to learn new skills and work collaboratively with other team members.

If you think that I am a suitable candidate for the project, I would be grateful for the opportunity to discuss it with you further. Thank you for considering my application.

Part B

42. Possible answer:

In recent years, the use of social media has become increasingly widespread. While social media platforms such as Facebook and Twitter have many benefits, they also have some drawbacks.

One of the main advantages of social media is that it allows people to connect with others from all over the world. This can be especially valuable for people who live in remote areas or who have limited social networks. Social media also provides a platform for people to share their ideas and opinions, which can help to promote free speech and democracy.

However, social media also has some disadvantages. For example, it can be a source of distraction and addiction, leading to decreased productivity and increased stress. Social media can also be a breeding ground for cyberbullying and hate speech, which can have serious consequences for individuals and society as a whole.

In my view, the benefits of social media outweigh the drawbacks, as long as we use it responsibly. We should be aware of the potential risks and take steps to protect ourselves and others from harm. By doing so, we can enjoy the many benefits of social media while minimizing its negative effects.

范文：

As the development of technology, more and more people get used to using electronic devices, such as smartphones and tablets. However, some people think that the excessive use of electronic devices has negative effects on people's health and social life. In my opinion, although electronic devices bring us convenience, we should use them in a proper way.

Firstly, the excessive use of electronic devices may cause health problems. For example, the radiation from electronic devices may harm our eyes and skin. Moreover, the overuse of electronic devices may lead to physical problems, such as neck pain and backache. Therefore, we should use electronic devices in a moderate way to protect our health.

Secondly, the excessive use of electronic devices may damage our social life. When we are addicted to electronic devices, we may neglect our family and friends. We may also miss some important social activities, such as parties and gatherings. Therefore, we should use electronic devices in a proper way to maintain our social life.

In conclusion, electronic devices are useful tools in our daily life, but we should use them in a moderate and proper way. We should pay attention to our health and social life while enjoying the convenience brought by electronic devices.
