(单选题)

What seems to be the effect of introducing the new system? ( )

A.The system has given equal opportunities to students.

B.The system has reduced the number of cram schools.

C.The system has intensified competition among schools.

D.The system has increased students’ study load.

参考答案：D

参考解析：

在第三段：But the new system has had the opposite effect. Before, students didn’t worry too much about their grade-point averages; the big challenge was beating the standardized tests as high-school seniors. A项曲解了原文意思，原文是说新考试制度需要高中生们用工在平常，而非一考定终身，排除A。B没有在问文中提到，可排除，C是说学生间的竞争激烈，而非学校，排除，D和原文说的意思接近，说明学生负担加重，故本题正确选项选D。
