from the graphs, we can see that grades have been rising rapidly. it can well be said that there is a grade "inflatiou."
take, for example, the stone mountain jr. college. in the fall semester of 1968, 16% of the students taking the exams received a's. however, in 1978, within ten years, the percentage went up by 13%. twenty nine percent of the students received a's. as for the b grade studems, in 1968, the percentage was 31%. ten years later, the percentage dropped to 26%. there was a 5% decrease, or rather, the students' grades rose by 5 %.
now let us have a look at the third graph, which shows that in 1968 37% of the examinees received c's while in 1978 the ratio fell to 21%. in other words, there was a 16% rise in grades.and in the forth graph, we can see that 8% of the students received d's. in 1978 only 4% of the examinees are d grade students. that means the grades doubled within ten years as compared to that of 1968. 蘇州易優(yōu)吳老師中考語文閱讀寫作培訓(xùn)（TEL:181-1815-9898）
the grade "inflation" puts me upon thinking whether students are working harder than ever or the teachers are being. lenient or cheating is on the rise. i hope for the beat.
