While Jennifer was at hose taking an online exam for her business law class，a monitor（監(jiān)控器）a few hundred miles away was watching her every move．
Using a web camera equipped in Jennifer's Los Angeles apartment ，he monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened 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 the cutting edge and a key to encourage honesty in the booming field of online education．The 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 just 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 number 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．

1．When I was a boy growing up in New Jersey in the 1960s，we had a milkman delivering milk to our doorstep．His name was Mr．Basille．He wore a white cap and drove a white truck．As a 5-year-old boy，I couldn't take my eyes off the coin changer fixed to his belt．He noticed this one day during a delivery and gave me a quarter out of his coin changer．
Of course，he delivered more than milk．There was cheese，eggs and so on．If we needed to change our order，my mother would pen a note-"Please add a bottle of buttermilk next delivery"-and place it in the box along with the empty bottles．And then，the buttermilk would magically（魔術(shù)般） appear．
All of this was about more than convenience．There existed a close relationship between families and their milkmen．Mr．Basille even had a key to our house，for those times when it was so cold outside that we put the box indoors，so that the milk wouldn't freeze．And I remember Mr．Basille from time to time taking a break at our kitchen table，having a cup of tea and telling stories about his delivery．
There is sadly no home milk delivery today．Big companies allowed the production of cheaper milk，thus making it difficult for milkmen to compete．Besides，milk is for sale everywhere，and it may just not have been practical to have a delivery service．
Recently，an old milk box in the countryside I saw brought back my childhood memories．I took it home and planted it on the back porch（門廊）．Every so often my son's friends will ask what it is．So I start telling stories of my boyhood，and of the milkman who brought us friendship along with his milk．
（1）Mr．Basille gave the boy a quarter out of his coin changer．
A．to show his magical power
B．to pay for the delivery
C．to satisfy his curiosity
D．to please his mother
（2）What can be inferred from the fact that the milkman had the key to the boy's house？
A．He wanted to have tea there．
B．He was a respectable person．
C．He was treated as a family member．
D．He was fully trusted by the family．
（3）Why does home milk delivery no longer exist？
A．Nobody wants to be a milkman now．
B．It has been driven out of the market．
C．Its service is getting poor．
D．It is forbidden by law．
（4）Why did the author bring back home an old milk box？
A．He missed the good old days．
B．He wanted to tell interesting stories．
C．He needed it for his milk bottles．
D．He planted flowers in it．發(fā)布：2025/1/1 16:0:1組卷：16引用：3難度：0.9 -
