答案 A Difficult Calculation A study shows that a group of second year high school students last spring/had the same scores on the same maths test that first year students had six years ago./In the opinion of the researchers/me main factor influencing this decline is/the pupils’ inability to do mental arithmetic/as a result of the emphasis on calculators./But the government gave its blessing to the use of calculators in schools/in a report published five years ago./The report suggested that "properly used in the classroom,/calculators can help and encour age children to improve their skills"./Inspectors thought that it was essential to make sure that/youngsters knew how to use them correctly and sensibly./The report suggests that not only should calculators be allowed in schools/but they should be introduced as a compulsory piece of equipment/for every secondary school pupil./
