阅读表达。

To the Editor:

     I have been reading your newspaper, the Hometown Gazette, for the past two years,ever since I moved to

Smithville. We moved here from New York City, so I am accustomed to reading excellent newspapers such as

The New York Times. In fact, we still have the Times delivered on Sundays. The entire family enjoys reading

the recipes in the paper, as well as the Styles section.

     The Times is great, but _____. I've never read an article that doesn't contain at least three or four spelling

or grammatical errors. For instance, in last week's issue, you misspelled the word "secretary", used a singular

verb with a plural noun, and used "it's" as a possessive. And that was just in the lead story! In case you never

went to elementary school, "it's" means"it is". It's not a possessive adjective!

     It's a pity that this tiny little hick (土气的) town has only one newspaper, because I'd like to have an

alternative to the rag you publish. I find it hard to believe your news stories. If you can't spell correctly, how

can you get your facts right?

     I've been meaning to get this off my chest for some time. Please cancel my subscription. And buy yourself

a dictionary. 

                                                                                                                                       Sincerely,

                                                                                                                                       Jane Z. Jones
