In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or dec ide it’ s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat if you pick them up within 5 seconds after dropping them. But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria(细菌) to make you sick.
Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.
One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.
But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna(大腊肠) on each surface for 5,30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.
So forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. This time, be careful not to drop it!
1. In which part of a newspaper can you most probably find this passage?
A. Culture B. Health C. Advertisement D. Technology

A. throw away dirty toast immediately and go away
B. pick up the toast as quickly as possible and eat it
C. eat the toast within 5 seconds and feel pleased
D. get another piece of clean toast quickly and eat it

B. show that the 5-second rule a correct
C. see how harmful bacteria are to people’ health
D. show that bacteria grow at different speeds on different foods

You’re rushing to work and a man ahead of you collapses on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people avert their gaze and keep on walking rather than stop and get involved.
“There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping.
● Why should I be the one? I’m probably not the most competent(有能力的)person in this crowd. You might think someone older or with more medical knowledge should offer assistance.
● What if he doesn’t really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.
● No one else looks concerned- this must not be a problem. We can follow the people around us, but most people tend to hold back their emotions in public.
“If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don’t have to take on the entire responsibility of being helpful. Sometimes it’s just a matter of turning to the person next to you and saying, ‘It looks like we should do something.’ Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you.”
1.Which is NOT the common thought that stops you from helping others?
A.I’m not the very person capable of setting the problem.
B.It looks like we should do something.
C.It must not be a problem as no one else is concerned.
D.He doesn’t really need my help.
2.According to a study of by-standers, what will some people do when a man ahead falls down on the sidewalk?
A.They will call for help and then walk away.
B.They will stop and offer help.
C.They will turn away their eyes and go on walking.
D.They will laugh at him.
3.We learn from the last paragraph that if we spot trouble, ________.
A.we should call the ambulance as soon as we can
B.we should stop and evaluate the situation and try to make other people follow
C.we should take on the whole responsibility and do something alone
D.we should turn to other people and ask them to take on the responsibility
4.In order to offer others your timely help, you need to________.
A.ask others for help and call the police
B.get along well with the passers-by who spot the trouble
C.go directly to the police station
D.work against the first thoughts that prevent you offering help
5.The main purpose of the text is to tell readers________.
A.to give others a hand
B.to be more competent
C.not to risk looking foolish
D.to stop and evaluate the situation

On the first day of school I brought my camera to school. I gave the students a piece of 8 ×11 cardboard(纸板), and asked them to write their names on both sides. As they finished, I asked them to get into groups of three to four students and took photographs of them holding their name cards.
After school, I developed the film and printed two sets of photos. That evening, I started to match the names with the faces. I kept one set of pictures at home for about a week so that I could review their names each night. On the second day of school, I put up the other set of photos as a bulletin board (公布栏), with a title such as "Presenting Room 108, ..."
The kids loved it! After I had learned all of their names I brought the second set back to school and stuck them onto an 8 ×11 sheet of paper. I placed it in the classroom for other teachers.
The cardboard name cards that were made on the first day were collected and put on a shelf. From time to time, they were given back to the students and placed on their desks so that guests or supply teachers (代课老师) could identify all of the students.
I’ve been doing this with my grade 7 students for the last nine years and they liked it. It’s fun to bring the photos out again at the end of the school year to see how much they have all changed in ten months.

A.play some kind of game B.decorate the classroom

Stepinac has become one of the first high schools in the country to drop all textbooks and replace them with a “digital library”. When students started classes on Monday, they were zipping to an app on their tablets or laptops and bad instant access to all 40 texts in the Stepinac curriculum (课程).
Dennis Lauro, director of an information center which provides technical support to public schools in New York, said neither he nor his colleagues were aware of a similar digital effort in a public school setting. “This is the wave of the future.” Lauro said. “I’m not surprised that a private school would beat the public schools to it. They have the ability to just do it. There is so much politics involved in public schools, when it comes to a move like that, needing approval from boards and committees.”
For Tom Collins, Stepinac’s president, the commitment to digital source material was not so difficult a decision. In the past, students’ families had to spend up to $ 700 a year on textbooks. This year — after the one-time purchase of a tablet or laptop — families only need to pay $ 150. Using the digital library is almost as easy as opening a new book. A student can instantly lap into a digital book and open a map of Egypt or a speech by President John F. Kennedy. A teacher can show a page from a digital book on a whiteboard at the front of the class or send students a link to a particular math problem with notes added in.
The first few weeks may bring some challenges. Stepinac officials expect some parental discomfort over dropping concrete books. They recognize there may be technical faults at first. And they will have to encourage students to leave space-eating photos and music off their tablets — and to keep their tablets charged.
1.What is going on in Stepinac?
A.It’s building a new library.
B.It’s reforming its textbooks.
C.It’s updating its digital resources.
D.It’s changing its management pattern.
2.By saying the underlined sentence. Lauro believes .
A.public schools face great challenges
B.private schools have their advantages
C.the effort is to cause instant changes
D.it’s a trend for schools to go digital
3.Who may worry about the move in Stepinac?
A.Officials. B.Technicians. C.Parents. D.Teachers.

Fatimah Bamun dropped out of Balizenda Primary School in the first grade, when her father refused to buy her pencils and paper. Only after her teachers said to him that his daughter showed unusual promise(有希望) did he change his mind. Today, Fatimah, 14, tall and slender, studies math in a dirt-floored fourth-grade classroom.
Whether she will reach the fifth grade is another matter. Fatimah is facing the realities of a school with no toilet, no water, no hope of privacy (隐私) other than the shadow of a bush, and no girlfriends with whom to share feelings. Fatimah is the only girl of the 23 students in her class. In fact, in a school of 178 students, she is one of the only three girls who have made it past the third grade.
“I have no friend in the class,” she said. “Most of my friends have dropped out to get married. So during the break, I just sit in the classroom and read.”
Her father, however, now says he is fully behind her. “The people from the government are all the time telling us to send our daughters to school, and I am listening to these people,” he said.
But in many cases, parents don’t listen. Parents think that if the girls stay home, they can help with the harvesting, fetch the water and collect the firewood. So they take them out of school.
In a region where poverty, tradition and ignorance make about 24 million girls not even have an elementary school education. There are many other barriers (障碍) that prevent girls going to school, such as the lack of school toilets and water.
The issue is not only equality. The World Bank thinks that if women in sub-Saharan Africa had equal education, land and other wealth, the region’s economy could improve greatly. There is a connection between growth in Africa and sex equality. It is of great importance but still ignored by so many people.
1.The author’s purpose in writing the passage is to _______.
A. find the cause of Africa’s poverty
B. describe the poor education conditions of African girls
C. prove the inequality in African society
D. reform the present schooling systems in Africa
2.Which of the following statements is NOT true according to the passage?
A. Fatimah is a girl who shows signs of success for the future.
B. Fatimah’s father is now giving a lot of support to her.
C. Fatimah is the only girl who has made it past the fifth grade in her school.
D. Fatimah has no friends at school because they most of them have dropped out to get married.
3.It can be inferred from the passage that _______.
A. most African girls are treated equally in society
B. African governments don’t care whether girls go to school or not
C. most African girls would rather get married than go to school
D. African girls can’t enjoy equal chances for education
