2016年11月5日北美SAT写作真题回忆 加试内容随机

北美11月SAT首次出现section 5的20分钟的加试,加试只在不考作文的学生身上出现(因此大部分学生并没有发现加试),加试内容随机,可能是阅读也可能是语法,但是题目比较少(语法只有18题),被认为比较简单。

我们推测12月SAT亚太和北美地区包括未来的SAT考试很可能延续这个趋势,就是不考作文的随机有加试,考作文的应该还是没有加试。毕竟又考作文又加试的话,考试时间会拉长到5个半小时,按道理不太现实。此举是CB为了检测试题难度还是有防作弊的意图暂不清楚。

Bad for the birds, bad for all of us

By John W. Fitzpatrick and and George Fenwick August 8, 2013

John W. Fitzpatrick is director of the Cornell Laboratory of Ornithology. George Fenwick is president of the American Bird Conservancy.

Like canaries in the c oal mine, declining bird populations across America’s grasslands are early warning indicators of much bigger ecosystem disruptions that affect us all. The birds are still singing to us, but they are doing so in greatly reduced numbers. They’re telling us t hat we need to do more, not less, to protect their precious habitats on our farms and ranches.

Over the past four decades, many birds once common in U.S. farmlands have become uncommon. The clear whistles of the Eastern Meadowlark ringing across a pasture are being silenced, as their population has plummeted 70 percent since 1970. The same is true for the diminutive and mysterious Henslow’s Sparrow — a prairie bird whose population may be down as much as 95 percent since the mid-1960s.

Yet, bright spots exist for both species, where local sub-populations are rebounding. In Illinois, recent spring counts of Henslow’s Sparrows are more than 25 times greater than they were in 1985. There is no mystery to these bright spots: The difference has been the farm bill’s Conservation Reserve Program (CRP), which pays landowners an annual per-acre fee to allow cropland to go fallow and then helps with the conversion to grassland. Henslow’s Sparrow counts are highest in Illinois counties with the most reserve program acreage.

The farm bill is not only important in helping our nation’s farmers produce food; it is also the biggest source of conservation incentives for private landowners. In addition to encouraging more grasslands, the incentives include paying some landowners to grow crops or graze cattle in a more sustainable manner. And as is shown in the recently published report “The State of the Birds 2013,” which we and several others helped compile, these conservation incentives.

Private farmlands provide critical bird habitat, with 80 percent of the populations of 29 vulnerable grassland-breeding bird species distributed across private lands. In the Prairie Pothole Region of the upper Midwest, farm bill CRP lands have produced a 30 percent increase in waterfowl breeding over the past two decades. Out west, the Sage Grouse Initiative has partnered with more than 700 ranchers to improve bird habitat on more than 2 million acres in 11 states, while promoting more nutritious grasses for grazing cattle.

But now farm bill conservation gains are at risk.

Last year, farm bill conservation spending totaled about $5 billion. Now, the House and Senate might not be able to reconcile their divergent versions of the 2013 measure.

Even if they do, both have substantially reduced incentives for conservation on farm lands. Sequestration is poised to reduce farm bill-sponsored conservation by $2 billion over the next 10 years, on top of the $3?billion in conservation funding reductions made over the past five years. In the past half-decade alone, the total acreage of grasslands enrolled in the CRP has decreased by 10 million acres (almost a one-third decline) .

The 20 farm bill conservation programs benefit far more than just birds. Many encourage and absorb the costs of transitioning to sustainable agriculture that yields both healthy food and vibrant ecological systems. For example, farm bill CRP lands have resulted in cleaner water, with 124 million pounds of phosphorous and 623 million pounds of nitrogen kept out of our nation’s waterways.

Yet even with 27 million acres enrolled in CRP nationally, our ecosystems are stressed. Record plantings in the Corn Belt are estimated to be more than 97 million acres —the most since 1936, during the Dust Bowl. Perhaps not coincidentally, a dead zone of oxygen-depleted water about the size of Connecticut now exists downstream in the Gulf of Mexico. (At about 5,800 square miles, this dead zone overlaps a vulnerable area still recovering from the

massive oil spill several years ago.)

Conservation is not a luxury. The prospect of no 2013 farm bill means that new CRP enrollments would stop, as would those for the similar Grassland Reserve and Wetlands Reserve programs, and longtime federal incentives for farmland conservation would be in serious jeopardy.

Besides birds, some of the biggest fans of farm bill conservation programs are farmers. Periodically, the Agriculture Department earmarks funds for conservation programs to be distributed in various regions around the country. New landowner sign-ups for these typically exceed the allotted funding, often meeting the quotas within days or even hours of their release.

It is essential that Congress pass a responsible farm bill this year, one that retains its historically vital conservation provisions. Without it, the silence of the birds will spread to new pastures and envelop our heartland.

三立在线课程培训优势

班级种类:(预约试听和科学选班请详询老师)

一对一在线授课班,其优势:一对一是指听说读写都由不同的老师教授,而不是由一位老师负责学生的全部课程。再加上督导顾问,总共是5位老师服务1位学员。一对一可以依据学生自身的优势弱势打造独一无二的学习计划,既避免了已熟悉知识点的无意义重复,又不会将学生还没掌握的重点难点一带而过。这不但大大节约了学习时间,提高了学习效率,而且又有人随时督促,提高学习积极性。同时在线授课突破时空限制,再忙的学员都能将有限的空闲时间利用起来;异地学员也能享受到海外名师授课,这在传统教学中是无法做到的。另外托福本身就是机考,平时在网络上上课,更有助于提前考试演练,熟悉考试流程。

课时学费:(具体的课时安排和学费优惠请详询老师)

经过专业的入学测试,根据学员的水平基础、想达到的目标分数、学习方便时间和个性需求等进行班级安排。所以,学习费用还要根据学员的实际情况而定。

致学员朋友:
