While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few

hundred miles away was watching her every move.

Using a web camera equipped in Jennifer'sLos Angelesapartment, the monitor inPhoenixtracked how

frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the

room. Her Internet access was locked remotely to prevent Internet searches, and her typing style was analyzed to

make sure she was who she said she was: Did she enter her student number at the same speed as she had in the

past？Or was she slowing down？

In the battle against cheating, this is thecutting edgeand a key to encourage honesty in the booming field of

online education. This technology gives trust to the entire system, to the institution and to online education in

general. Only with solid measures against cheating, experts say, can Internet universities show that their exams

and diplomas are valid — that students haven't searched the Internet to get the right answers.

Although online classes have existed for more than a decade, the concern over cheating has become sharper

in the last year with the growth of "open online courses". Private colleges, public universities and corporations are

jumping into the online education field, spending millions of dollars to attract potential students, while also taking

steps to help guarantee honesty at a distance.

Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular.

Among them are programs that check students’ identities using personal information, such as the telephone

numbers they once used.

Other programs can produce unique exams by drawing on a large list of questions and can recognize possible

cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many

university classes, term papers are scanned against some large Internet data banks for cheating.

Did you know that horses talk? Well, they do, and you can lean to understand “horse talk” if you pay close

attention to the horses you see.

When horses live in the wild, other animals try to eat them, so a lot of horse talk is about staying alive. Even

now, when most horses live on farms, they watch for danger. For this reason, never walk behind a horse. If you

surprise it, the horse might mistake you for a mountain lion or wolf and give a dangerous kick.

By watching the ears of a horse, you can get clues to what it's hearing. A horse can tum each ear in a different

direction. For a wild horse, this trick is important for survival. The horse can hear something sneaking up behind it

while also checking out a threatening noise in front. When a horse lets its ears down, it's feeling safe and relaxed.

If horses becomeisolated, they neigh, or “whinny,” calling for company. They're saying, “Where are you? I'm over

here!” If a horse snorts(哼) while holding its head high and staring at something, it's saying, “That looks dangerous.

Get ready to run!” When two horses meet, they put their noses together and smell each other's breath. It's their

way of asking, “Are you a friend?” Horses nicker,too. Nickering is a quiet sort of sound. This friendly noise means

they're feeling secure and saying, “Clad to see you.”

In the wild, horses live in herds, with all members watching for danger. In a herd, only one horse is the leader,

the “boss hoss”. The “boss hoss” is usually an older female. She watches for threats and teaches younger horses

how to behave. However, others may want her job. When that happens, she pins her ears back against her head

and may even bite or kick to get challengers to back off. She's using body language to say, “Hey, I'm in charge here!”

All horses know that the one who makes others move is the leader. Horses relate to people that way, too.

Horses have a language of their own. Now you know a bit of what they might be saying.
