Using technology, of course. While special services via webcam(摄像头)and cheating detecting software have been developed now, Mettl, an online company, has developed advanced techniques for netting cheaters, which the company claims are even more reliable and easier to use. Whatever small attempt to cheat, he or she will be found out.
Mettl has adopted a handful of technologies on its test—taking platform, creating a mini monitoring state in an exam. Here’s how it works:A test-taker signs on to Mettl and selects his/her exam from the site’s library of pre—loaded tests. Facial and keystroke recognition technology confirm the person that has signed in is the very person, and the system records both the test—taker(through the webcam)and the test—taker’s screen throughout the test.
Mettl’s technology uses the test—taker’s webcam to detect how many people are using the computer. Soon, it will track eye movement well enough to sense whether the test-taker is looking away from the screen, perhaps to Consult a smart phone or a friend in secret. Mettl also monitors the test-taker’s screen and can detect when the test-taker has changed a computer or moved from the test. The system will soon be able to record sound, thus detecting whether the test-taker is talking or being talked to.
If any irregularities are detected, the system flags the incident and reports it back to the test’s administrator. This can bring any number of things, depending on the test-giver’s wishes:a complete shutdown of the exam, a warning message that appears on the test-taker’s screen, even human instructions from the control center.
Mettl is hoping its technology will help it break into the country’s big MOOC markets.

Hot weather kills hundreds of people every year. The World Health Organization estimates that from 1998 to 2017 more than 166,000 people died as a result of extreme heatwaves. That includes the more than 70,000 people who died during the 2003 heatwave in Europe.

A person’s age and weight play a part in surviving high temperatures. People over 65 and under 2 are especially at risk of becoming sick from heat.

【推荐1】Earlier this month, two high school students from Longmont, Colorado, US, led a gardening lesson for fifth graders from Burlington Elementary School.
Burlington, in Longmont, is one of 10 local primary and high schools benefiting from an $11, 700 grant (拨款) from the Farm to School program supported by United States Department of Agriculture. The grant aims to build on ongoing nutrition education, add farm-to-school training and create gardening mentorships (导师制) . For the mentorship program, about 125 high school students are participating to help school garden education.
Kate likes the idea of volunteering with younger students. She noted that many school gardens are currently empty. “It gives the kids responsibility to care for plants.” she told Daily Camera. “It’s always so much fun to play with dirt. It’s very beneficial to energetic kids.”
In addition to small gardens at the schools, the grant helps to build greenhouses to enable students to grow food. Last summer, the teacher Jennifer arranged a “salad day” harvest for students at the Burlington Elementary School. She guided kids to water the plants in a greenhouse garden twice a day. This semester, kids have planted tomato and herb seeds with the help of the high school students. Later this spring they will work with the student union on a plant sale.
Several Burlington fifth graders are also making a short film about the greenhouse and its origins. They recorded the whole process of establishing the greenhouse. Roman described the process as beautiful, especially now that planting has started. “It could inspire people to grow healthy plants at home,” she said.

【推荐2】Writing an article for your school newspaper can be exciting and rewarding, especially when you proudly see your name in print.
Decide on a topic.
Do your research. There is an old saying in law that a good lawyer never asks a question that they don’t know the answer to.
Attract the readers with a lead. As the beginning of a newspaper story, a lead has to be direct, but it does not mean you don’t need to entertain the reader as well.
Consider the 5Ws and H. These are the meat and potatoes of your news articles. You article must answer all of these questions: Who, What, When, Where, Why and How. Once you have answered these things, you can feel confident.
Write, edit, rewrite and repeat as necessary. So, much about having a successful final product is about being willing to spend time and effort in editing and reviewing process.
A.Think about what is happening on campus. |
B.You have effectively informed your readers. |
C.Get them interested with an interesting beginning. |
D.Do not be afraid to accept positive comments. |
