Step 3. 写作技巧（20）

• Writing Skills — How to write aproblem-solution essay

A problem-solution essay is one type of argumentative writings. As it says, it essentially has to explain the problem and propose solutions.

²  There are usually four parts in this type of essay:

① Introduction: Present the thesis statement.

② Problem: Identify and describe the problem.

Define the nature of the problem. What is the problem? What are the causes or the impacts of the problem?

③ Solution: Propose possible solutions.

Put forward solutions and develop them with more details.

④ Conclusion: Sum up or call to action.

Re-emphasize the importance of the problem and the value of the proposed solutions.

²  For example:

In the text, the author first presents his argument that digital technology can fundamentally reorganize life for the poorest people in the world. (Introduction)

Then he raises the problem that Africans fail to grow crops in line with the needs of the market because of the information disconnect. (Problem)

To deal with the problem, he proposes using digital technology to bridge the information gap between African smallholders and consumers. (Solution)

Finally, he summarizes his points by stressing the possibility of applying digital technology to the agricultural development. (Conclusion)

2) Skills practice

Read the essay and fill in the table.

The news industry has had a rough decade. Print readership is steadily declining, newspapers are closing, and journalists with decades of experience are being laid off. In response, major newspapers have made considerable changes.Here are three ways newspapers are using social media to save the industry. First, interaction. A key contributor to the decline of the newspaper industry has been the surpassing of baby boomers by Generation Y; a shift that accounts for the decrease in print readership and increase in digital. Through repeated interaction (hash tags, tweets, Facebook groups & posts), optimizing this expanding force is key to reviving the newspaper industry. Second, audience data. Registrants are prompted to provide the email, zip code, industry, job responsibility and position level – valuable information that allows publishers to re-aim their creative initiatives and target their readers' interests. Third, mobile penetration. As mobile plays a critical role in driving real-time active use of social platforms in all markets, it is imperative for publishers to capitalize on the shift that is occurring.
