Air quality in Shanghai worsened last week compared with the previous week, according to the latest report from the Shanghai Environment Monitoring Centre.
The average air pollution index (API) for sulphur dioxide (SO2) remain almost unchanged from the previous week, but the APIs for nitrogen oxide (NOx) and total suspended (悬浮) particles (TSP) rose by 35 and 27 percent. The overall quality still belonged to class 2 category. Nitrogen oxide, caused mainly by vehicle exhaust and burning of cooking gas, was still the major pollutant of the week.
The Shanghai Environmental Monitoring Centre operates six automatic air monitors in the city’s Putuo, Yangpu, Luwan, Hongkou, Jing’an and Xuhui districts.

Sometimes life gets a little dull. What used to be fun and different becomes boring. That is the time to look for something new. It is the time for a big idea to get your mind off everyday life. So why not search for extraterrestrial (地球外的) intelligence? Or even better, why not get your computer to do it for you?
Over two million people have joined the Search for Extraterrestrial Intelligence（SETI）project. Based in California, the SETI project analyzes information taken from a giant radio telescope based in South America. Its task is to look for signals from outer space that might prove that life exists on other planets.
Processing this information is far too big a job for one computer. So the SETI project workers divide the work among volunteers who visit their website. Each computer gets some information to work out from the SETI network through the Internet. This process is often known as “meta-computing”.
It is a wonderful thought. You are sleeping, eating a meal or going out with friends. All this time, your computer is searching the stars for signs that might show something is out there trying to get in touch. Volunteers are proud of being involved in the SETI project. It shows that they understand the potential (潜能) of computing. They know that it is more than just a way of working or playing games.
Meta-computing may also be creating intelligence as well as looking for it. This idea is based on the theory that human intelligence is created by the way in which different parts of the brain communicate with each other. As the saying goes, “The whole is more than the sum of its parts.” People who join the SETI project sometimes wonder whether their computer will become part of a huge network that has learned to think for itself.
1.According to the writer, meta-computing may be creating intelligence .
A. because human beings are intelligent B. because a computer works as the brain does
C. because of a network of many computers D. because of the number of computers
2.Which of the following shows the order in which the SETI network works?
A. Radio telescope→SETI website→Volunteers’ computer→SETI base
B. Radio telescope→SETI base→SETI website→Volunteers’ computer
C. SETI base→SETI website→Volunteers’ computers→Radio telescope
D. SETI base→Radio telescope→SETI website→Volunteers’ computers
3.The underlined word “it” in the last paragraph refers to .
A. extra-terrestrial intelligence B. human intelligence
C. the SETI projectD. meta-computing
4.The passage mainly tells us about .
A. a new way to work on the computer
B. a new way to work and play games
C. a new way to search for life outside the earth
D. a new way to make life interesting and different
“I don’t want to write a story about girls! I don’t know anything about girls,” Louisa May Alcott told her publisher, Mr. Niles. But she was desperate for money. She seemed to be the only one in her family who could make any money. Niles had asked her to write about something she knew, instead of the romantic adventure stories she had been writing. “So I plod away,” Alcott wrote, “though I don’t enjoy this sort of thing.” It was 1867, and the horrible Civil War was over. Now Alcott could turn her energy to making money.
Alcott wrote a simple story of life in her family, their pillow fights on Saturday nights and the amateur (业余的) plays they performed. “Our experiences may prove interesting, though I doubt it.” (“Good joke,” she wrote years later.) Her book described her days growing up with four sisters in a family that had no money. She sketched (勾画) a loving mother who took time to be interested in each child, and she told of the death of a beloved sister. She portrayed her family and friends in her book Little Women. Finally, in July of 1868, she finished writing. With a sigh and a headache, she sent off all 102 handwritten pages of her book.
Niles thought the book was dull, and so did Alcott. But when she received her copies of the book, Alcott thought it seemed better than expected. “Not a bit sensational,” she wrote, “but simple and true. We really lived most of it.” Niles asked some girls to read Little Women, and they loved it.
In three months, all the copies of Little Women had sold. It was already time to print more books! Niles thought he could sell three or four hundred more copies. “An honest publisher and a lucky author made a dull book into a golden egg for an ugly duckling,” Alcott wrote in 1885. Later, with a great sigh of relief, she was able to write, “Paid off all the debts! Now I feel that I could die in peace. If my head holds out, I’ll do all I once hoped to do.”
