What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations. Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.What makes a scientist according to the passage?

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.

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.

It was graduation day at the university where I work and a beautiful day quite unlike the first graduation I attended as a young professor. On that cold day years ago, as we watched the students walking into the hall, one of my colleagues turned to me and said, "Graduation will be one of the happiest and one of the saddest time of your life. "At my inquiry, he answered, "Because the students you have gotton to know have to leave."
As years went by, my previous confusion about my colleague's words no longer existed. When I came across naughty students, I had to rethink why I chose to be a teacher. It obviously isn’t money. Once a former computer science student of mine called me, asking me if I wanted to have a change .He was working at Nintendo Corporation. His salary was higher than my current one, though I have more education and have worked for over a decade, with my programming skills, he said he could get me hired. I thanked me, but declined his kind offer.
A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework. She thanked me for being her teacher and said the things she had learned in my class — not about my math, but about life — would be things she would remember long after the math skills had faded away. As I finished reading, I remembered why I had become a teacher.
Now, on this sunny graduation day, as I again observed the sea of blue hats and gowns .I did so with renewed dedication and a deeper sense of sati faction – I wi11 always be grateful that I am teacher.

Until the 1980s, the American homeless population was made up of mainly older males. Today, homelessness strikes much younger part of society. In fact, a 25-city survey by the U. S. Conference of Mayors in 1987 found that families with children make up the fastest growing part of the homeless population. Many homeless children gather in inner cities; this transient(变化无常的) and frequently frightened student population creates additional problems, both legal and educational, for already overburdened urban school administrators and teachers.
Estimates of the number of homeless Americans range from 350,000 to three million. Likewise, estimates of the number of homeless school children vary radically. A U.S. Department of Education report, based on state estimates, states that there are 220,000 homeless school-age children, about a third of whom do not attend school on a regular basis, But the National Coalition for the Homeless estimates that there are at least two times as many homeless children, and that less than half of them attend school regularly.
One part of the homeless population that is particularly difficult to count consists of the “throwaway” youths who have been cast of their homes. The Elementary School
Center in New York City estimates that there are 1.5 million of them, many of whom are not counted as children because they do not stay in family shelters and tend to live by themselves on the streets.
Federal law, the Stewart B. McKinney Homeless Assistance Act of 1987, includes a section that addresses the educational needs of homeless children. The educational provisions(规定) of the McKinney Act are based on the belief that all homeless children have the right to a free, appropriate education.
64. What can be implied from the first paragraph?
A. Before the 1980s, the homeless population mainly consists of children.
B. Urban schools are seriously short of academic facilities.
C. Many homeless children gather in inner cities.
D. Homeless children are deprived of the opportunity to receive free education
65. The National Coalition for the Homeless believes that the number of homeless children is ___
A. 350,000 B. 440,000 C. 3,000,000 D. 220,000
66. The reason why one part of the homeless population is difficult to estimate might be that ___
A. the homeless children are usually making a living by themselves
B. the homeless population is growing very fast.
C. some homeless children are abandoned by their families
D. the homeless children usually don’t attend school regularly
67. The McKinney Act is mentioned in this passage in order to show that ____________.
A. all homeless people are allowed to receive a good education
B. there is an increasing number of homeless children in America
C. it is necessary for homeless children to be counted as children
D. the educational problems of homeless children are being recognized
