如何处理给水泵速度控制失灵？

答案：

参考答案：

若能手动调节给水量，则根据固定负荷对应的给水量来调节水位；如不能调节，则对安全的威胁更为严重，只能短时根据给水量来稳定负荷，并尽快联系检修人员予以修复。在整个处理过程中，应设专人调节，严禁水位和汽温超限。

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(习惯的) 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（食谱） in the magazine, as well as the Styles section.

The Times is great, but the Gazette is another story. 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 (所有格). And that was just in the lead story! In case you never went to elementary school, “it’s” means “it is ”.It’s also a possessive adjective!

It’s a pity that this tiny little hick(乡下) town has only one newspaper, because I’d like to have an alternative(替换物) 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(订阅). And buy yourself a dictionary.

Sincerely,

Jane Z, Jones
