Theme-Related Writing

▆ Write a passage in about 100-120 words, taking either of the following titles:

1) Why I like to learn English 2) Why I hate to learn English

▆ Sample essay for Task 1:

Why I like to learn English

I have learned English for about seven years. I should say that I am highly motivated to master English.

First of all, learning English is useful, as it is becoming a world language and people from different countries often communicate with one another in English. If I am good at English, it will be much easier for me to communicate with them. Secondly, I like traveling a lot. A good mastery of English will make things much easier for me when traveling around the world. Finally, I like literature a lot. If I am very good at English, I can read great works by Shakespeare and Dickens and many other English writers instead of reading the translated versions.

▆ Sample essay for Task 2:

Why I hate to learn English

I have learned English for about seven years. I should say the more I learn English, the more I hate it. First of all, learning English is boring. I have to memorize many new words or rely on a dictionary to frequently check unknown words. Doing so wastes a lot of my precious time. Secondly, I don’t understand why we have to learn a foreign language. I don’t want to go abroad and I can always find a job that doesn’t need English in China. Finally, I can always read translated versions of the books I want to read. So, if I don’t have to learn English, I would rather use the time I spend on English to do things I like.
