What is the senior project?   The Senior Project at Clark Magnet High School is a program that shows a senior's ability to apply knowledge and skills, speak, write, solve problems and practice the life skills of time management, organization and risk-taking. Clark teaching staff, community members and school district staff act as advisers, evaluators during the research, project and presentation stages.  The key parts of the Senior Project are: 1) A research paper  A six to eight page persuasive research paper on a topic chosen by the students. The research paper strengthens effective writing skills learned in English class. Because the paper is persuasive, students should choose a topic about which they have a strong opinion. They should use elements learned when debating to convince the readers of the strong opinion stated in the paper, and prove it through research.   2) A physical product and fieldwork  A physical product and fieldwork (15-hour minimum requirement) related to some aspect of the paper. The 15 hours can be obtained through community service, job shadowing, or making an actual project. Students explore topics that are academic in nature, a hobby, a passion, or a possible future career.   3) Data collection Data collection that combines the first two parts and records hours spent on the fieldwork. The collection contains evidence of the fieldwork presented through letters from the students' advisors, pictures showing the process of the project or anything else that would show proof of the work completed.    4) Speech presentation A fifteen minute speech presented before a review board composed of school staff, district representatives, former students, and community representatives. The speech is a chance to show the students' senior project. Students are to dress professionally and summarize their senior project journey. Students will talk briefly about their research paper, their project, and what they learned. The speech should include visual aids. If the presentation includes performing,... What must the students do when they present their final project? A) Give a performance. B) Make a formal speech. C) Introduce some video aids. D) Report the details of the process.

Which are you more likely to have with you at any given moment-your cell phone or your wallet? Soon you may be able to throw your wallet away and pay for things with a quick wave of your smart phone over an electronic scanner. In January, Starbucks announced that customers could start using their phones to buy coffee in 6,800 of its stores. This is the first pay-by-phone practice in the U.S., but we're likely to see more wireless payment alternatives as something called near field communication (NFC) gets into America's consumer electronics. Last December, some new smart phones which contain an NFC chip were introduced to the public. Already in use in parts of Asia and Europe, NFC allows shoppers to wave their phones a few inches above a payment terminal - a contact- free system built for speed and convenience. But before NFC becomes widely adopted in the U.S., a few problems need to be worked out, like who will get to collect the profitable transaction fees. Although some credit card providers have been experimenting with wave-and- pay systems that use NFC-enabled credit cards, cell phone service providers may try to muscle their way into the point-of-sale(POS)market. Three big cell phone service providers have formed a joint venture that will go into operation over the next 15 months. Its goal is "to lead the U.S. payments industry from cards to mobile phone." The other big NFC issue, apart from how payments will be processed, is security. For instance, what's to stop a thief from digitally pick-pocketing you? "We're still not at the point where an attacker can just brush against you in a crowd and steal all the money out of your phone," says Jimmy Shah. A mobile- security researcher, "Users may also be able to set transaction limits, perhaps requiring a password to be entered for larger purchases." Still uneasy about this digital-wallet business? Keep in mind that if you lose your smart phone, it can be located on a map and remotely disabled. Plus, your phone can be password protected. Your wallet isn't. What is predicted to happen in the U.S.? A) The expansion of cell phone companies. B) The boom of pay-by-phone business. C) The disappearance of credit cards. D) The increase of Starbucks sales.

Drinking more than two alcoholic drinks daily in middle-age may raise your stroke  risk more than traditional factors such as high blood pressure and diabetes , according to new research in the American Heart Association journal Stroke. In a study of 11,644 middle-aged Swedish twins who were followed for 43 years, researchers compared the effects of an average of more than two drinks daily ("heavy drinking") to less than half a drink daily ("light drinking"). The study showed that: *Heavy drinkers had about a 34 percent higher risk of stroke compared to light drinkers. *Mid-life heavy drinkers (in their 50s and 60s) were likely to have a stroke five years earlier in life _ of genetic and early-life factors. *Heavy drinkers had increased stroke risk in their mid-life compared to well-known risk factors like high blood pressure and diabetes. *At around age 75, blood pressure and diabetes appeared to take over as one of the main influences on having a stroke. Past studies have shown that alcohol affects stroke risk, but this is the first study to pinpoint differences with age. "We now have a clearer picture about these risk factors----how they change with age and how the influence of drinking alcohol shifts as we get older," said Pavla Kadlecova, M.Sc., a statistician at St. Anne's University Hospital's International Clinical Research Center in the Czech Republic. Researchers analyzed results from the Swedish Twin Registry of same-sex twins who answered questionnaires in 1967-1970. All twins were under age 60 at the start. By 2010, the Registry had provided 43 years of follow-up, including hospital discharge  and cause of death data. Researchers then sorted  the data based on strokes, high blood pressure, diabetes and other cardiovascular  incidents. Almost 30 percent of participants had a stroke. They were categorized(......) as light, moderate, heavy or non-drinkers based on the questionnaires. Researchers compared the risk from drinking and health risks like high blood pressure, diabetes and smoking. Among... What does the passage mainly tell us? A) People without a stroke can drink more alcohol than those having a stroke in middle age B) There is a higher possibility that heavy drinkers will have a stroke in middle age C) Drinking alcohol has been regarded as the most dangerous factor in strokes D) The amount of alcohol taken by men should be twice than that taken by women.
