Taking a picture of your tongue with a mobile phone could soon instantly tell you how healthy you are. Researchers believe the images can reveal important information about a patient's health and even give them early warning of serious illness. A team at the University of Missouri is developing a system that can analyze pictures using a 5,000-year-old Chinese principle, which is based on the flow and balance of positive and negative energies in the body, and uses the tongue as a key to learning about a person's physical health, or "zheng" according to Chinese medicine. "Within a year, our goal is to create an application for smart phones that will allow anyone to take a photo of their tongue and learn the status of their zheng," said Dong Xu, chair of MU's Computer Science Department in the College of Engineering and the co-author of the latest study. The software analyzes images based on the tongue's color and coating to distinguish between tongues showing signs of "hot" or "cold" zheng. Shades of red and yellow are associated with hot zheng, whereas a white coating on the tongue is a sign of cold zheng. "Hot and cold zheng doesn't refer directly to body temperature," said Xu, "Rather, it refers to a series of symptoms associated with the state of the body as a whole." For the study, 263 gastritis patients and 48 healthy volunteers had their tongues analyzed. The gastritis patients were classified by whether they showed infection by a certain bacteria as well as the intensity of their gastritis symptoms. In addition, most of the gastritis patients had been previously classified with either hot or cold zheng. This allowed the researchers to test the accuracy of the software's analysis. "Our software is able to classify people based on their zheng status. And as we continue to work on the software we hope to improve its ability," said another co-author Ye Duan, "Eventually everyone will be able to use this tool at home using webcams or smart phone applications, which will allow them to monitor their zheng and... It can be inferred from the passage that _ . A) the software still needs improvement B) the subjects in the study are all gastritis C) the software has been in market for a year D) the subjects in the study are classified by age

Q: It is a truth universally acknowledged that . However little known the feelings or views of such a man may be on his first entering a neighborhood, this truth is so well fixed in the minds of the surrounding families that he is considered the rightful property of someone or other of their daughters. "My dear Mr. Bennet," said his lady to him one day. "have you heard that Netherfield Park is let at last?" Mr. Bennet replied that he had not. "But it is, " returned she, "for Mrs. Long has just been here, and she told me all about it." Mr. Bennet made no answer. "Do you not want to know who has taken it?" cried his wife impatiently. "You want to tell me, and I have no objection to hearing it." This was invitation enough. "Why, my dear, you must know, Mrs. Long says that Netherfield is taken by a young man of large fortune from the north of England; that he came down on Monday in a chaise to see the place, and was so much delighted with it, that he agreed with Mr. Morris immediately; that he is to take possession before Michaelmas, and some of his servants are to be in the house by the end of next week." "What is his name?" "Bingley." "Is he married or single?" "Oh! Single, my dear, to be sure! A single man of large fortune; four or five thousand a year. What a fine thing for our girls!" How so? How can it affect them? "My dear Mr. Bennet," replied his wife, "how can you be so tiresome! You must know that I am thinking of his marrying one of them." "Is that his design in settling here?" "Design! Nonsense, how can you talk so! But it is very likely that he may fall in love with one of them, and therefore you must visit him as soon as he comes." "I see no occasion for that. You and the girls may go, or you may send them by themselves, which perhaps will be still better, for as you are as beautiful as any of them. Mr. Bingley may like you the best of the party. " From the conversation between the Bennets, we can conclude that Mrs. Bennet _ . A) wanted to persuade her husband to visit the young man B) wanted to get an invitation from their new neighbor to a party C) asked for her husband's permission to visit the new neighbor D) wanted to tell her husband something about their new neighbor
