▆ Answers for reference:

Nowadays, many people are enjoying the benefits brought about by material and technological advances unimaginable in previous eras. With the development of science and technology, people’s standard of living is getting higher and higher. People’s life exp ectancy has soared, too.

However, oddly enough, many people do not feel happier than they used to be. It can be seen that there is no close correlation between people’s income and their happiness. Happiness cannot, after all, be bought with money.

Although the majority of people are not very satisfied with their lives, they are happy to be alive, and the more time they live on earth, the better off they feel they’ll be. What is important is that material wealth is far from enough. People need spiritual happiness, too.

▇Sample essay:

The Impact of the Mobile Phone on People’s Lives

Among the many technological inventions, the mobile phone impresses me most.

The mobile phone brings considerable convenience to our lives. It not only enables us to keep in touch with each other almost anytime and anywhere but also helps us solve problems or do business efficiently. In emergencies, a mobile phone can even be a life-saver. Besides, its multi-functions add ease and color to our lives. With a mobile phone, we can receive mail, read news, listen to music, play games, and take pictures.

Yet, the mobile phone has its disadvantages, too. Most of us have experienced the nuisance of unwanted or wrong calls. We are inconvenienced by calls on occasions when we least expect one. Besides, the technology infrastructure to support mobile communication has consumed valuable natural resources and caused significant environmental problems. It is reported that electromagnetic radiation waves from the phone may result in health problems.

Despite its negative side, the advantages of the mobile phone outweigh its disadvantages. I believe that with advances in science and technology, improved and safer models of mobile phones will surely serve us still better. (184 words)
