Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free – by spreading on them cheese brine, the salty liquid used to make soft cheese, like mozzarella.
Wisconsin, also called "America's Dairyland," is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! a result, there was a lot of leftover cheese brine. Disposing of(处置)the brine can be expensive. So what should cheese makers do with the waste?
Normally, towns use rock salt to de-ice streets. The salt lowers waters' freezing point, causing ice to melt(融化). But using cheese brine could help both cheese producers and cities save money, while keeping roads safe. Cheese brine has salt in it, which, like the rock salt, helps lower water's freezing point.
In addition to saving money, cheese brine could also be a more environment-friendly option. Many people suspect that all the rock salt used every winter is harming the environment.
Rock salt is made of sodium chloride, the sane con-pound (化合物)in ordinary table salt. Sounds harmless, right? But while you probably add only a small amount of salt to your food, road crews spread about 20 million tons of salt on U.S. Roads every year!
The chemical washes off roads and goes into the ground. There it can pollute drinking water, harm plants. and eat away soil. By spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.
Cheese brine has a downside too – a shell similar to that of bad milk. "I don't really mind it," Emil Norby told Modern Farmer magazine. He works for one of Wisconsin's county highway commissions and came up with the idea of using cheese brine. "Our roads smell like Wisconsin!" he said.

I never knew anyone who’d grown up in Jackson without being afraid of Mrs. Calloway our librarian. She ran Jackson’s Carnegie Library absolutely by herself. SILENCE in big black letters was on signs hung everywhere. If she thought you were dressed improperly, she sent you straight back home to change your clothes. I was willing；I would do anything to read.
My mother was not afraid of Mrs. Calloway. She wished me to have my own library card to check out books for myself, She took me in to introduce me. “Eudora is nine years old and has my permission to read any book she wants from the shelves, children or adults,” Mother said.
Mrs. Calloway made her own rules about books. You could not take back a book to the library on the same day you`d taken it out；it made no difference to her that you’d read every word in it and needed another to start. You could take out two books at a time and two only. So two by two, I read library books as fast as I could go, rushing them home in the basket of my bicycle. From the minute I reached our house, I started to read. I knew this was extreme happiness, knew it at the time.
My mother shared this feeling of mine. Now, I think of her as reading so much of the time while doing something else. I remember her reading a magazine while taking the part of the Wolf in a game of "Little Red Riding Hood" with my brother's two daughters. She'd just look up at the right time, long enough to answer– in character –"The better to eat you with, my dear," and go back to her place in the magazine article.
1.Which of the following best described Mrs. Calloway?
A.diet. B.Strict. C.Humorous. D.Considerate.
2.What do the underlined words "this feeling" refer to in the last paragraph?

C.Interest in games. D.Fear of the library rules.
3.Where is the text probably from?
A.guidebook. B.an autobiography. C.a news report. D.book review.
