Home Schooling
All children in the United States have to receive an education, but the law does not say they have to be educated at school. A number of parents prefer not to send their children to school. 46 There are about 300, 000 home-schoolers in the United States today. Some parents prefer teaching their children at home because they do not believe that public schools teach the correct religious values;others believe they can provide a better educational experience for their children by teaching them at home. 47
David Guterson and his wife teach their three children at home. Guterson says that his children learn very differently from children in school. 48 For example, when there is heavy snowfall on a winter day, it may start a discussion or reading about climate, snow removal(去除)equipment, Alaska, polar bears(北极熊), and winter tourism. A spring evening when the family is out watching the stars is a good time to ask questions about satellites and the space program. 49
Home schooling is often more interesting than regular schools, but critics say that home-schoolers are outsiders who might be uncomfortable mixing with other people in adult life. 50 However, most parents don't have the time or the desire to teach their children at home, so schools will continue to be where most children get their formal education.
A Interestingly, results show that home-schooled children quite often do better than average on national tests in reading and math.
B Critics also say that most parents are not well qualified to teach their children.
C Learning starts with the children's parentsinterests and questions.
D Children who are educated at home are known as “home-schoolers”.
E In some countries, however, children are educated by their parents.
F If the Brazilian rain forests are on the TV news, it could be a perfect time to talk about how rain forests influence the climate, and how deserts are formed.

Passage Two
Questions 62 to 66 are based on the following passage.
Scientists have devised a way to determine roughly where a person has lived using a strand(缕) of hair , a technique that could help track the movements of criminal suspects or unidentified murder victims .
The method relies on measuring how chemical variations in drinking water show up in people’s hair.
“You’re what you eat and drink, and that’s recorded in you hair,” said Thure Cerling, a geologist at the University of Utah.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as raid clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid falls first .As a result, storms that form. over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a mop of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops.
They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.
“It’s not good for pinpointing (精确定位),” Cerling said . “It’s good for eliminating many possibilities.”
Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.
The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.
When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months.
She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.
“It’s still a substantial area,” Park said “But it narrows it way down for me.”
62. What is the scientists’ new discovery？
