     As students and teachers returned to school on Monday after the publication of performance ratings

(等级) for 18,000 teachers, many parents said they were giving the reports serious thought. Yet there

was an equal measure of skepticism among parents that test scores have any relationship with teachers'

competence.

     Some said they already knew how good a teacher was by walking into the classroom or by

monitoring their children's progress. "I'm the kind of person who likes to see for themselves," a father in

Queens said.

Others worried about how their fellow parents, perhaps ones with sharper elbows, might respond. Will

they demand a new teacher? Move their children to a new school?

     Elizabeth Sane, the mother of a fourth grader at the Ella Baker School, a kindergarten-through-eighth-

grade school on the Upper East Side, said that her daughter was switched to a different teacher's class

over the summer, and that it was "like adding salt to the wound" when she saw the high ratings for her

daughter's previous teacher. Her daughter's teacher this year did not receive a rating because he

previously taught high school.

     Ms. Sane said that the rating was not the only factor that influenced how she assessed a teacher's

performance, but that the data used for teacher evaluations mattered.

But other parents dropping their children off at the Ella Baker School said they did not trust teacher

ratings based on test scores any more than they wanted their children's learning measured only by the

state exams.

    "Some people take it as the final word, but it doesn't change who they are as teachers. The ratings

aren't accurate, and the whole student testing thing needs to be thrown out," said Lydia Delgado, whose

child is in the second grade.

A. All the teachers received a rating given by the students.

2.What does the underlined part "with sharper elbows" mean?

C. With a stong will to succeed.

D. With strong elbows physically.

3.Paragraph 4 shows that Elizabeth Sane         

A. was on the side of giving ratings to the teachers.

B. regretted having sent her daughter to another class.

C. didn't think her daughter's previous teacher was better.

D. wanted her daughter to return to her previous class.
