▆ Answers for reference:

Nowadays, many peopleare enjoying the benefits brought about by material and technological advancesunimaginable in previous eras. With the development of science and technology,people’s standard of living is getting higher and higher. People’s life expectancyhas soared, too.

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

Although the majorityof 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. Whatis important is that material wealth is far from enough. People need spiritualhappiness, too.

▇ Sample essay:

The Impact of the MobilePhone on People’s Lives

Among the many technologicalinventions, the mobile phone impresses me most.

The mobile phone brings considerableconvenience to our lives. It not only enables us to keep in touch with eachother almost anytime and anywhere but also helps us solve problems or dobusiness 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 mobilephone, we can receive mail, read news, listen to music, play games, and takepictures.

Yet, the mobile phone has itsdisadvantages, too. Most of us have experienced the nuisance of unwanted orwrong calls. We are inconvenienced by calls on occasions when we least expectone. Besides, the technology infrastructure to support mobile communication hasconsumed valuable natural resources and caused significant environmental problems.It is reported that electromagnetic radiation waves from the phone may resultin health problems.

Despite its negative side, theadvantages of the mobile phone outweigh its disadvantages. I believe that withadvances in science and technology, improved and safer models of mobile phoneswill surely serve us still better.  (184words)
