{{B}}The Price Problem of
Universities{{/B}}
When it comes to tuition (学费) breaks at
well-known universities, it may sound like a good idea. However, they might not
be as good as what they were expected.
Stanford is one of the
latest universities that announce a new financial-aid package for those
middle-class families. Harvard University was the first one to come to the aid

In a few weeks, nigh school students face the prospect of taking the much-publicized new SAT Reasoning Test, which for the first time will require them to write a timed essay. Yet colleges continue to send confusing signals about whether students applying in the fall to attend college must take the new exam.
Some schools, including Harvard, say they will accept scores from either the new test or the old SAT, which was administered for the last time in January and did not contain a writing section. The University of Central Florida, for example, will require the new test, which will be given for the first time on March 12. Still others, such as the University of Virginia, strongly recommend that prospective applicants take the new test but under some circumstances also will accept the old SAT. A number of colleges are delaying a decision. The College Board, which administers the SAT, surveyed more than 1,900 four-year schools and has heard back from slightly more than 500.
A. Students who have taken the old test are strongly advised not to take the new test.
B. As compared with the old test, the new one requires the student to write an essay in a shorter period of time.
C. The College Board has decided to invite university teachers to grade the essays.
D. The College Board has appealed to many universities to support the new examination.
