Now that American education has entered the era of the MOOC—the Massive Open Online Course-the opportunity for cheating appears greater than ever. The all-knowing Google search engine is never more than a few keystrokes away. So how can a teacher manage such a large number of examinees so far away, let alone searching out cheaters taking tests across the Internet?
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.

文章大意:本文是一篇说明文。本文就如何让一般学生成长为优等生提供了一些建议。

【推荐1】Maybe you are an average (一般的) student. You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here’s how:

    1     When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule (计划) of your time. First your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don’t forget to set aside (留出) enough time for entertainment. A weekly (每周的) schedule may not solve all your problems, but it will force (强迫) you realize what is happening to your time.

    2     . Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but (除了) study materials (材料). No games, radios, or television. When you sit down to study, concentrate on (集中精力) the subject.

    3     There are other methods that might help you with your studying. Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

    4     . When you get home from school, go over (复习) your notes, review the important points that your teacher is going to discuss the next day, read that material. This will help you understand the next class. If you do these things regularly, the material will become more meaningful (有意义的), and you’ll remember it longer.

    5     . The purpose (目的) of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don’t pass a test, so don’t be over-- worried.

【推荐2】Staying Safe in Hot Temperatures

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.

    1    . There are steps you can take to stay safe during periods of very high temperatures. Many things can affect your body’s ability to cool itself during extremely hot weather. For example, when the wetness is high, body sweat will not dry as quickly. This restricts the body’s ability to release heat.     2    .

Also, take note of nighttime temperatures. Experts say heat waves often become dangerous when the nighttime temperature does not drop much past the highest daytime temperature.     3    . So, hot nighttime temperatures put great pressure on the human body.

    4    . Alcohol, caffeine, and sugar, for example, can weaken the body’s system for cooling itself.

On its website, the Centers for Disease Control and Prevention, or CDC, explains that some people are at high risk of suffering from heat-related illnesses. 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.

Your general health is also a very important factor to consider.     5    , you must move to a cool place, loosen your clothing, put a cool wet cloth on your body or take a cool bath and drink water.

Experts at the CDC say that “everyone should take these steps to prevent heat-related illnesses, injuries, and death” when the weather is very hot.

A.If you have health problems
B.Since mental illness can bring greater risk
C.Some foods can also affect the body’s temperature
D.Yet, heat related deaths and sickness are preventable
E.Contact your local health department quickly, if possible
F.Our bodies repair themselves at night when we are sleeping
G.So, pay attention to not only the temperature but also the level of wetness
