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’s Los Angeles apartment, the monitor in Phoenix tracked 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 the advanced technique 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(有效的) - 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 exam 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.Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To prevent her from slowing down. |
| D．To keep her from dishonest behaviors. |
For Internet universities, exams and diplomas will be valid if _____.
| A．they can attract potential students |
| B．they can defeat academic cheating |
| C．they offer students online help |
| D．they offer many online courses |
Some programs can find out possible cheaters by _____.
| A．checking the question answering speed |
| B．producing a large number of question |
| C．scanning the Internet test question |
| D．giving difficult test question |

When I was going home to India last year, I called up my mother to ask if she wanted anything from China．
When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and jeans．Thankfully, we can get all these anywhere in India now．
Still, her answer surprised me: “Green tea．”
As long as I can remember she didn’t even drink Indian tea ．
I dutifully bought a big packet of Longjing and headed home to hear the story．My mother and her brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all illnesses．
At the turn of the century, China was not really familiar to the average Indian．It was a strange country．
How things change! And how soon!
Now every town of any size seems to have a “China Market”．And everyone is talking about China．
The govemment of Indin has planned to send a team to China to see how things are done．A minister once said that India must open the doors for more foreign investment(投资)and such a step would “work wonders as it did for China”．
But it’s a two-way street．I just heard about a thousand Shenzhen office workers who have gone to Bangalore to train in software．Meanwhile, all the Indian IT majors are setting up a strong presence in China．
No wonder that trade, which was only in the millions just ten years ago, is expected to hit about US $15 billion for last year and US $20 billion by 2008, a goal set by both governments．
No wonder, my colleague wrote some weeks ago about this being the Sino-Indian(中印)century as the two countries started on January 1 the Sino-Indian Friendship Year．
But what is still a wonder to me is my mother drinking Chinese tea．According to the passage, the author left _____ for ______．
| A．India; China | B．China; India |
| C．China; Longjing | D．India; Shenzhen |

| B．China and India have different traffic rules． |
| C．Tea trade works wonders in both India and China． |
| D．Chinese produces are popular in both China and India． |

All too often , a choice that seems sustainable（可持续的）turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol（乙醇）for fuel from corn . Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea.
One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land — including, in some cases, rain forest in places such as Brazil — into farmland, which in turn gives off lots of carbon dioxide（CO2）into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
You cannot really declare any practice “sustainable” until you have done a complete lift-cycle analysis of its environmental（环境的）costs. Even then, technology and public policy keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainable requires plenty of thought on an ongoing basis.What might directly cause the loss of the forest according to the text?
| A．The growing demand for energy to make ethanol. |
| B．The increasing carbon dioxide in the air. |
| C．The greater need for farmland. |
| D．The big change in weather. |
The underline word “it” in the second paragraph refers to
| A．the energy benefit | B．the forest loss |
| C．climate change | D．burning ethanol |
The author thinks that replacing gas with corn ethanol is
| A．impractical | B．acceptable | C．admirable | D．useless |
What does the author mainly discuss in the text?
| A．Technology. | B．Sustainability. |
| C．Ethanol energy. | D．Environmental protection. |
Cities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.
A pedestrian is killed in a traffic accident in the USA every 110 minutes；one is injured every nine minutes, according to official date. Crosswalk can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared with 21% of those younger than 70, according to the Insurance Institute for Highway Safety.
The Federal Highway Administration（FHWA）advises that next year states increase by nearly 15% the amount of time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears .
FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of drive.
Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006. But among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration (NHTSA) says.Which of the following is true according to the text?
| A．Among 100 pedestrian deaths there were 21 people younger than 70. |
| B．Old people are more likely to meet with accidents in crosswalks. |
| C．Traffic accidents killed more old people than young people. |
| D．About seven traffic accidents happened per hour. |
What is FHWA’s suggestion to states?
| A．Fixing more traffic lights. |
| B．Providing more crosswalks. |
| C．Giving pedestrians more time to cross streets. |
| D．Increasing the time before the orange lights appear. |
What’s the cause of the crosswalk safety problem according to the test?
| A．There’re many cars and buses on the road. |
| B．Pedestrians are careless. |
| C．Crosswalks are crowded. |
| D．Drivers don’t give way. |
The report from NHTSA suggests that
| A．fewer people were injured in crosswalks |
| B．crosswalk safety has been greatly improved |
| C．much has been done to reduce traffic accidents |
| D．pedestrian deaths in crosswalk remain a serious problem |
