Is the Artificial-intelligence surveillance at work a good thing or bad thing? Technology has transformed the way people work. While it is believed by some that surveillance at work has a positive effect on both companies and individuals, others think that this behaviour does more harm than good. In my opinion, I strongly support the former view. First of all, surveillance at work improves productivity for companies. The reason for this is because surveillance at work allows the manager to have extraordinary control over the staff. For example, the manager will find out whether the staff is dozing off during work hours. In addition, by analyzing the data gathered from workers, AI helps the manager to ensure that pay rises and promotions go to those who deserve them. Besides, staff will benefit from the surveillance too. This is because AI can check that employees are wearing safety gears and no one has been harmed at the factory floor. However, surveillance at work comes with negatives too. One of the major drawbacks of surveillance is that employees would have little privacy. This is because few laws govern how data should be collected at work, and staff may unguardedly consent to surveillance when they sign their employment contract. Additionally, AI-system may have some unintended consequences. For example, when the work performance is based on staff's productivity, older staff may less likely to excel young workers, which is apparently unfair to for older staff. Taken together, although surveillance at work can be an invasion of privacy and a biased tool to judge staff's capability, I personally think the benefits of doing this, such as boosting productivity and keeping staff safe, eventually outweigh any of the negatives.

【IELTS】Do you agree or disagree with the idea that library should provide books only? Thank you! Spending leisure time in the public library is a popular choice for many people due to the convenience and quietness of the environment. While it is believed by some that public libraries should spend their money on books only, others think that a reasonable budget should also go to the installation of high-tech facilities. In my opinion, I strongly support the latter view. First of all, although spending money on high-tech devices can be expensive, it is a sensible investment in the long run. This is because the storage of paper books takes a large amount of space and management of these books also consumes considerable human resources. In contrast, books that are stored in the hardware or cloud does not take up so much space. Furthermore, searching specific content in electronic books would be much more efficient than looking up information in paper books. Another reason why high-tech equipment should be installed is that learning on these subjects is entertaining, especially for children. For example, it is difficult to ask a child to sit by the desk and concentrate on paper books for hours, while learning via high-tech media such as tablets, is a fascinating experience for kids as the information is delivered in a vibrant and interactive manner. Consequently, children would not be bored and would be more likely to enjoy the process of learning when studying on the high-tech. To conclude, although it could be expensive to provide high-tech devices in public libraries, there are a wide range of benefits for doing this. I personally think the positives of the installation of high-tech facilities such as making the learning enjoyable and saves resources of the library, eventually outweighs any negatives.
