科目:高中英語 來源:2013屆江蘇南京三中(六中校區(qū))高二下學(xué)期期末英語試卷(解析版) 題型:閱讀理解

Kuss Middle School serves students in Fall River, Mass. , a former mill town that has struggled economically for decades. Students at Kuss have struggled, too, usually falling short of making the academic progress required under the No Child Left Behind law.

Then, last year, the school experimented with extending the school day. Teachers got paid at a higher hourly rate.

Students weren't thrilled at first with leaving school at 4:15 p.m. instead of at 2:20 p.m. But the added hours gave them more time for physical education and let them select special interest classes. By the end of the year, student scores had risen by enough to enable Kuss to make the progress required under the federal No Child Left Behind law.

The only surprise is that more districts haven't lengthened school schedules set decades ago to accommodate (適應(yīng)) a farm economy rather the information economy of today.

School days

The USA ranks 36th of 40 industrialized nations in average weekly instructional time.

Selected countries:

1) Thailand--30.5 hours  2) Korea--30.3 hours  7) China--26.5 hours

14) France--24.6 hours  15 ) UK--24.6 hours

16) Mexico--24.2 hours  23 ) Japan--23.8 hours

26)Canada--23.6 hours  36)USA--22.2 hours  40)Brazil--19 hours

New research suggests the time is ready for a change:

Matched against 39 other developed countries, the United States is near the bottom in the rankings of average weekly instructional time in school.  Measured over 12 years, students in the top-scoring countries spend the equivalent of a full extra year in school.

US students perform poorly on math and science tests compared to their international peers, according to a US Education Department comparison released earlier this month. In math, American 15-year-old scored near the bottom among the study's 30 developed countries.

Most countries that boost the number of minutes spent on math instruction find pay offs in improved math scores, according to a study released this month by the Brookings Institution. Small in creases in the school day are more effective than a longer school year, the report concluded.

The most encouraging news about the benefits of extending the school day comes from Massachusetts, where an experiment with 10 schools, including Kuss, appears to be working. Those 10 schools lengthened their instructional days by 25% and boosted their state scores in math, English and science at all grades.

Perhaps the concept won't work everywhere. Certainly, it won't instantly be popular. But it's obvious that a problem exists or that adding class time seems to help.

A.Experiments with extended school hours produce academic gains.

3.Which statement is true of Kuss Middle School?

B.Kuss Middle school has joined the federal "No Child Left Behind" progrann
