1. Some people think that robots are very important for humans’ future development. Others, however, think that robots are a dangerous invention that could have negative effects on society. Discuss both views and give your opinion.
The field of science and technology has advanced throughout the past decades and has changed our perspectives of life. Among those advancements, robots have become significant by trying to get close to human lives. While some people argue that though these robots have managed to solve most of our day-to-day problems, they can still create problems, I believe that robots are significant for humans’ current and future development.
It is normal for people to be worried about the rise of robotics in every aspects of our lives. In workplace, one of the real impacts humans face is the loss of jobs and the economic displacement of workers. As prices continue to drop for advanced technology, the result is that robots cost less than a human does to complete the same job. Consequently, wages are slashing and pay inequality is worsening. Moreover, when societies become too dependent on robots, humans become lazy and begin to lose the skills that they has replaced. Last but not the least, it’s not a stretch to imagine that untrustworthy robots may cause over-trust issue and deception. As anthropomorphic robots come to the physical world, people, children particularly, are susceptible to telling their deepest, darkest secrets to these robots whose cute faces may hide exploitative code.
Nevertheless, the benefits that robots bring about could outweigh these potential risks. Many robotic solutions have been introduced in order to help disabled people. For example, wheelchairs, robotic arms, and many other robotic devices are created to help the disabled to perform their day-to-day tasks. Moreover, some of the greatest technologies are now in medicine, particularly with robot surgeons. In addition, robots are used in many high end factories to make their production lines more efficient and time saving. Compared with humans, robots rarely make mistakes and are more precise. As long as they have power, they can work continuously without any pauses or breaks and does not get tired as humans.
In conclusion, there are good aspects as well as bad aspects about robots being a part of our lives. As long as humans remember that it is we who should decide on how much we let them control our lives, we could enjoy the life with robots around.

2. Today, advanced science and technology have made great changes to people’s life, but artists such as musicians, painters and writers are still highly valued. What can arts tell us about life that science and technology cannot?
Almost every aspect of modern human life has been influenced by science and technology. One area where technology is already having a profound impact is the world of art. Art is one affected and redefined by technology in a new way. Yet, some people argue that even with advance technologies that enable faster creation of works, artists are still high valued. I totally agree with this idea since efficient creation does not necessarily mean highly appreciable works.
Admittedly, technology is shedding light on the ability to duplicate and create arts. For example, pianist robots are created to sit in front of a piano center stage and move their fingers with great accuracy and speed to play a piece from Mozart. Additionally, sketching portraits of humans, spontaneously composing music, and writing traditional Chinese calligraphy are already possible in the world of robots. Further, digitizing artwork help to make it more accessible to a wider audience. Livestreaming opera performance, for instance, enables people to enjoy the show online at home instead of taking a trip. Lastly, advanced technology have also allowed contemporary artists to reduce time spent in the actual execution of artwork to a minimum thereby freeing them to focus more on contemplation, creativity and developing groundbreaking ideas, as well as sound preparation for artwork. 
Nevertheless, technology unavoidably surface a lot of works with less artistic value and will never outshine artists’ creativity and imagination. The interpretation and creation of music is basically the expression of feelings. For example, when an artist sees beautiful scenery, he may immediately make a sketch, paint then, or just write a poem about what he saw. In contrast, machines that humans are used to operating as tools have little emotive understanding of the social, historical, psychological and physiological factors that inspire human artists, which makes it difficult to accept them as having the ability to be creative.
In conclusion, contemporary art has been greatly influenced by the rapid development in digital technology. Given that these influences are inevitable, artists need to hone their skills and understand these techniques well in order to translate their vision and creativity into great and distinctive art pieces.
3. Nowadays, high-technologies such as mobile phones and internet are rarely used by old people. How should these technologies be useful to old people? How to encourage old people to use the technologies.
Seniors consistently have lower rates of technology adoption than the general public. Given that high-technologies and internet could certainly benefit the elderly, it is necessary to come up with solutions to encourage them to take advantage of technologies.
Both technologies and internet are useful to old people in all aspects of their life. Firstly, the elderly could maintain constant contacts with their relatives, friends, and children via video chat services like Skype, or other Internet-based communication channels such as email and social media. Secondly, smart technologies can assist older people to live safely and live well at home. With certain devices like a watch, senior people could easily call for help in case of emergency with the simple push of a button. Further, there are video games designed to help seniors exercise physically and mentally. For example, owning a Wii or other video game system offer a fun opportunity for old people to engage in light physical activity from the comfort of their own living room. Lastly, smartphone apps and cloud-based health information tracking systems can help seniors and their family caregivers keep information such as medical history, physician contacts, medication schedules, and health conditions organized and handy.
However, older adults do face some unique barriers and challenges when it comes to adopting new technologies and Internet. In order to make seniors become perfectly capable of using new devices and visiting digital world, it would be helpful to develop devices tailored to the aging population and provide them with the right training. Currently, the reality is that a lot of applications and devices are designed mainly for the young, which makes it hard for old people to utilize. Therefore, high-tech companies and organizations should take the unique features of seniors into account in the R&D process. Communities and governments should organize some public classes specifically for the aging citizens to train them how to surf online, use smartphones, and other useful devices and applications. The aging populating themselves should be open to new technologies and actively engage in the learning process.
In conclusion, technologies generally lead to a healthier lifestyle by helping senior citizens stay in touch with people, maintain their health, manage diseases and conditions, and tract treatments. Old people themselves, communities, and governments should work together to increase the rates of technology adoption by seniors.

4. Some people believe that computers and internet carry more weight than traditional education in children’s study. Some others believe that traditional schooling and teachers are still essential and more effective. Discuss both viewpoints and give your own opinion.
It is undeniable that computers and internet has played an increasingly significant role in education. More and more schools and institutions start to adopt such advanced technologies to educate children, but I believe that traditional schooling and teachers should still play the dominant role.

Indeed, children can get a variety of benefits from using advanced computers and the Internet. Firstly, there are a wide range of information and knowledge that covers all areas, such as mathematics, literature, and geography, available online. In other words, children can now access information on every conceivable subject. Secondly, the Internet together with computers make education an equal opportunity for every child, especially for those who in impoverished and remote areas without any access to schools and teachers. Thirdly, computers allow students to have e-mail or other forms of internet-based conversations with experts on any subject around the world. No longer will students be limited by their own classroom or teachers. Lastly, the Internet has created a creative and interesting learning environment where children can explore, convey, create knowledge as never before.

However, compared to computers and the Internet, traditional schooling and teachers are still important and more effective. To begin with, teachers know well about their students and normally impart them the most relevant and valuable knowledge. On the contrary, finding and retrieving information from a web site can be sometimes tedious and time-consuming. Moreover, children are too young to develop self-control and self-discipline ability. Therefore, the supervision and guidance from teachers become fundamental and necessary. Further, schooling provides children with a collective and interactive environment where they can learn not only from their teachers but also from their peers and classmates. Only in this way can they develop team work and cooperation skills which are essential and indispensable for their future life and career.

In conclusion, despite the convenience and popularization of the Internet and computers, teachers and schools are still play an significant and irreplaceable role in children’s education. Yet, educational experts and institutions could take advantage of these advance technologies to offer better education to students.

5. Universities and colleges are now offering qualifications through distance learning from the Internet rather than teachers in the classroom. Do you think the advantages of this development outweigh the disadvantages?
Distance learning has become increasingly popular, and Universities and institutions are offering an enormous range of Undergraduate, Postgraduate, as well as short-term courses. Some people argue that this development could worsen the quality of teaching and learning, while I think there are many obvious advantages in using distant education.
Online colleges have been criticized for a variety of reasons. Firstly, some say that the quality of online education cannot be comparable to face-to-face learning since the main driver for opening up online courses is to spend less on teachers and buildings. Secondly, there is no direct contact with faculty. Lack of personal interaction with teachers could affect the learning curve for some students. Thirdly, students, especially those lack of self-control and selfdiscipline, are likely to fail in courses since without teachers they will not take distance learning seriously. The last argument is that qualifications offered by distant learning are not valued by employers. Some employers will always prefer a candidate who has pursued a regular program over holders of the distance learning program qualification.
However, the advantages of distant education outweigh the above mentioned disadvantages. One of the biggest advantages of studying from home is the cost comparative to studying full time at school. Internet-based education usually involves more affordable tuition than traditional college or university. In addition, part time distance learning students can work while studying towards their qualification. Also, with web-based classes, students are capable of saving time far more since they do not need to travel to schools for all classes registered. This enables those who have a job or have important personal responsibilities, like looking after family members, to get their degrees. Moreover, some accelerated programs enable students to complete their education in a short period and they can engage and pursue a career faster as well by completing a degree earlier.
In conclusion, although distance learning is not suited for everyone, it does allow individuals who cannot attend regular education programs to get educated and gain their qualification.
