Europe’s deadly outbreak of a rare form of E. coli bacteria (大肠杆菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(肠) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
What is the main topic of the text?

A.Bacteria. B.A high-tech scanner. C.A camera D.Food safety.

E. coli bacteria ______.

A.broke out all over the world B.comes from soil or animal waste
C.is extremely harmful to health D.does not cause illness

The high-tech scanner ______.

A.can help to sort out different fruits
B.make the produce appeal to shoppers
C.can only capture images of the whole apple
D.can identify the presence of contaminants

What can be inferred from the text?

A.The scanner needs to be improved.
B.The scanner will be available in the next several years.
C.Moon Kim is unwilling to develop the scanner.
D.The scanner is connected to a sorting machine.

During the twentieth century there has been a great change in the lives of women. A woman marrying at the end of the nineteenth century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which chance and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and can be expected to live another thirty-five years and she is likely to take paid work until sixty.
This important change in women’s life has only recently begun to have its full effect on women’s economic(经济的) position. Even a few years ago most girls left school and took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen; many girls stay at school after that age, and though women marry younger, more married women stay at work at least until shortly before their first child is born. Many more afterwards return to full-time or part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life.

For almost two months Dominic York, a 23-year-old hairdresser, wandered about hospitals all night, wearing a white coat and pretending he was a doctor. Yesterday he proudly claimed in court that despite his complete lack of medical experience or qualifications, he had saved several people’s lives. He had even been allowed to assist a surgeon during an emergency operation on a patient who was about to die on something she had swallowed.
“I watched one of those TV dramas about a hospital and suddenly I felt like playing one of the roles myself. So I put on a white jacket and a stethoscope(听诊器)and walked around one of the biggest hospital in London. At first I just watched. Once you learn how doctors talk to patients, nurses and others doctors, it’s easy to take people in,” he said.
One of the patients he treated was Laura Kennan. She had been knocked down by a car and fainted. When she came to in hospital, York was standing over her.
“He looked very professional. He told me his name was Doctor Simon. Then he gave me some sort of injection,” she said. And then he suddenly cleared off when a nurse asked who he was. She didn’t think there was anything wrong. “I would never have realized he was a fake if a policewoman hadn’t showed me his photograph a week later. When the policewoman told me who he really was, I could hardly believe my ears.”
Judge Raymond Adams told York that he was “ shocked and horrified” that he got away with his deceiving for so long, and then sentenced him to eighteen months in a special prison for criminal with mental disorders.
“I can only hope that this will not lead to further problems. After all, you will have considerable opportunity to study the behaviour of the psychiatrists(精神科医生)who will look after you while you are there. If you try to persuade people that you yourself are a psychiatrist after you are set free, I shall make sure that you are given a much longer sentence.” Judge Adams warned York.

A. a surgeon let him watch an operation.
B. he could perform some duties of a doctor.

Every day, all across the nation, as many as one in four children refuse to go to school. The reasons are various. "School Refusal," formerly known as ''School Phobia", is an actual anxiety-based disorder. Many children are vague about their complaints and unable to be sure what is making them anxious, so it is sometimes regarded as typical childhood will fullness. However, the effects of constant school refusal can be far-reaching for your child’s education.
So, where's the 1ine between what's normal and what's not? "You need to look at whether it is affecting the child or family's normal life," explains Christopher Kearny, Ph.D. In other words,
if a child's grades are suffering from frequent absences or a parent’s job is disturbed, it is time to look closely at the issue. Parents should listen carefully to children who say they can’t go to school because of “untestable things" such as stomachaches or headaches. While these complaints alone don't necessarily indicate school refusal, there may be deeper problems if combined with general complaints about school, talks of threats at school and so on.
There are different kinds of behavior in school refusal. Some children are influenced by their friends who skip school to hang out with their friends, showing a sense of rebellion(叛逆).
Some children cling to their mother's, screaming at the thought of having to enter the school bui1ding.
However, that doesn't mean that getting a child back into the c1assroom is impossible. According to Maryann Roth, a school psychologist and guidance counselor(顾问), parents should attempt to make the child get back to school, no matter how hard it is. Working closely with school officials and possibly a specialist to create a plan is a necessary step.
67. The underlined word 'vague' (Paragraph l) is closest in meaning to _______.
A. irregular B. unclear C. curious D. unusual
68. According to Paragraph2, the real reason of "School Refusal" may be that the children___________
A. are suffering from illness B. are afraid of endless tests
C. want to stay with their parents D. feel bored and unsafe at school
69. When facing "School Refusal" of their children, parents should _________.
A. take the problem serious1y if their daily life is disturbed
B. discuss the seriousness of the problem with their children
C. take their children to see the doctor immediately
D. keep their children away from their rebellious friends
70. The passage intends to ________.
A. explain that "School Refusal" is a symptom of an illness
B. explain the phenomenon of 'School Refusal" and how t treat it
C. remind parents to take good care of their children
D. explain that ‘Scholl Refusal’ is normal and not serious

With smart phones taking the world by storm, a phone that can only send and receive voictcal1s and text messages may seem like a relic from a bygone age. Yet in East Africa, simple phones like these are changing the face of the economy, thanks to the mobile money services that are spreading across the region. Using the text--messaging function built into the GSM system(全球通) used by most cell phone networks, these services al1ow people without a bank account or credit card to use their/phone as an electronic wallet that can he used to store, send or receive cash.
It works like this: you pay cash to your loca1 agent who then tops up your mobile money account using a secure form of text messaging. That money can be transferred to another person by sending a message to their cell Phone account.
Fur some the system is a lifeline. ''If I didn’t have my mobile Phone, I would be very poor," says Neyasse Neemur, a mother of four chi1dren who lives in northern Kenya. .”Now I can sell fish.” Neemur took up fishing in Ju1y last year, but making money from it was a little tricky, especially as Turkana peop1e do not usually eat fish. A truck from Ethiopia to Tanzania passes through her vi1lage once a week, and she arranged to have the driver transport the fish several hundred ki1ometers south to market in Kisumu, where relatives sell the fish.
"I get the money transfer immediately.” says Neemur . "Then I can pay for my children to go to school and for vegetables and beans," she adds, "so I don't need to eat fish."
According to the Central Bank of Kenya, payments worth around l billion Kenyan shillings($13 million) per day were transferred through Kenya’s mobile money systems in 2009, equaling the country’s credit card transactions(业务). The bank expects mobile money transfers to overtake credit cards in 2010.
63. In Paragraph l the author uses "simple phones" to _______________________.
A. make a comparison B. introduce a topic C. describe a scene D. offer an argument.
64. What can we learn about the simple phones in East Africa?
A. They might help the local peop1e apply for a bank account.
B. They will replace the banks completely in the near future.
C. They Provide a safe means for the locals to do business.
D. They can do nothing except send and receive calls or messages.
65. The word “It” in the third paragraph refers to _____________________.
A. the GSM systemB. the mobile money service
C. the credit card service D. the cell phone networks
66. The story of Neyasse Neemur suggests that ___________________.
A. the mobile money service plays a key role in the locals life
B. Neemur uses her mobile phone to contact her customers
C. her relative' tricks Turkana people to eat the fish they sell
