单选题In education, changing patterns of school attendance required new ways of thinking. As late as 1870, 【C21】______families needed children at home to do farm work, Americans attended school for an average of only four years. By 1900, however, cities contained multitudes of children who had more time for school. Compulsory-attendance laws 【C22】______children to be in school to age fourteen, and swelling populations of immigrant and migrant children jammed schoolrooms. Before the Civil War, the curriculum had consisted chiefly of moral lessons. But in the late nineteenth century, the psychologist G. Stanley Hall and the philosopher John Dewey asserted that modern education ought to prepare children【C23】______. They insisted that personal development, not subject matter, should be the focus of the【C24】______. Education, argued Dewey, must relate directly to experience; children should be encouraged to discover knowledge for themselves. Learning 【C25】______to students' lives should replace rote memorization and outdated subjects. Progressive education, based on Dewey's books The School and Society(1899)and Democracy and Education(1916), was a uniquely American phenomenon. Dewey believed that learning should focus on real-life problems and that children should be taught to use their intelligence and ingenuity as 【C26】______for controlling their environments. From kindergarten through high school, Dewey asserted, children should learn 【C27】______direct experience. Dewey and his wife, Alice, put these ideas into【C28】______in their own Laboratory School, located at the University of Chicago. A more practical curriculum became the driving principle behind reform in higher education as well.

But in the late 1800s, institutions of higher learning multiplied. Curricula【C30】______as educators sought to make learning more appealing and to keep up with technological and social changes.

单选题About myopia—if you have it, be happy. As shown by numerous scientific studies, nearsighted men and women boast a higher average intelligence than their nonmyopic cohorts. The precise mechanism of this association remains unknown, but it is tempting to postulate an effect of myopia on early childhood development. Most nearsighted kids wander around undiagnosed for years, and during this formative period—unable to see the baseballs, Frisbees, and rocks thrown at them by their playmates—they spend a lot of time indoors. The nonathletic myopias who take up reading to while away the hours get high scores on the SATs, while those who take up eating tweak our claustrophobia by overflowing the adjacent seat on airplanes. Myopia also exerts a compelling influence on career choice: the great majority of my fellow ophthalmologists wear either contact lenses or thick myopic spectacles. Pathology breeds preoccupations. However beautiful the human eye, it serves a more important purpose than romantic allure. Forty percent of the brain is devoted to vision, which provides us with more information than our other four senses combined. Our optic nerves transmit millions of impulses to the brain every second, impulses that specify the location, color and intensity of light for all the points in our visual space. Better yet, thanks to a mysterious algorithm that fuses the slightly disparate images from each of our eyes, our visual cortex, via a neurological miracle known as depth perception, shows us the world in three dimensions. An impressive feat since a video camera, arguably the benchmark of modern technology, can muster only two dimensions. Certain ocular tissue stands on the pinnacle of evolution. How does nature, so crude in claw and fang, create a surface that brings light into a pinpoint focus? This surface must be perfectly curved, perfectly transparent, perfectly smooth. It must be—water! Which is to say, the cornea owes its optical perfection to a tear film whose dissolved salts, lipids, and proteins maintain a flawless wetted surface. A man who has no tears stands on the brink of blindness. Worse yet, that man will writhe in agony: a dry cornea, thanks to the most exquisite pain threshold in the human body, responds to each blink with a tormenting jolt. Dry eye victims compare the sensation to that caused by rubbing the eyeball with shards of glass.
