[单项选择]A cramped public-school test kitchen might seem an unlikely outpost for a food revolution. But Collazo, executive chef for the New York City public schools, and scores of others across the country -- celebrity chefs and lunch ladies, district superintendents and politicians -- say they’re determined to improve what kids eat in school. Nearly everyone agrees something must be done. Most school cafeterias are staffed by poorly trained, badly equipped workers who churn out 4.8 billion hot lunches a year. Often the meals, produced for about $1 each, consist of breaded meat patties, French fries and overcooked vegetables. So the kids buy muffins, cookies and ice cream instead -- or they feast on fast food from McDonald’s, Pizza Hut and Taco Bell, which is available in more than half the schools in the nation. Vending machines packed with sodas and candy line the hall ways. "We’re killing our kids" with the food we serve, says Texas Education Commissioner Susan Combs.

[单项选择]It might seem natural to gauge the amount of discrimination in labor markets by looking at the average wages of different groups. For instance, in recent years the wage of the average black worker in the U.S. has been about 20 percent less than the wage of the average white workers. The wage of the average female worker has been about 30 percent less than the wage of the average male worker. These wage differentials are sometimes presented in political debate as evidence that many employers discriminate against blacks and women. Yet there is an obvious problem with this approach. Even in a labor market free of discrimination, different people have different wages. People differ ill the amount of human capital they have and in the kinds of work they are able and walling to do. The wage differences we observe in the economy are, to a large extent, attributable to the determinants of equilibrium wages. Simply observing differences in wages among broad groups say little about the prevalenc
A. Even in a labor market freedom is valued, different people have different wages.
B. Even in a labor market full of discrimination, different people have different wages.
C. Even in a labor market with discrimination, different people have different wages.
D. Even in a labor market without discrimination, different people have different wages.

It might seem odd to think of pre-kindergarten toddlers as students in need of teachers, but the latest research suggests that some form of instruction may help children to better prepare for school.
Nina Chien, a post doctoral researcher in pediatrics at the University of California San Diego found that children who were left to engage in free play in pre-kindergarten centers showed the least improvement in reading and math skills after one year compared with the children who benefited from some form of teacher instruction. The free play groups were provided with educational toys designed to stimulate their creative and cognitive processes, but they still learned up to two fewer alphabet letters and three fewer numbers than those who worked with teachers. Overall, when the children reached kindergarten, their teachers rated them up to 96% lower on language and literacy skills compared to their classmates.
Chien based her study on 701 state-funded pre-kindergarten
A. upgrading
