以下有关"调节准确度"的说法，错误的是（）。

A.调节准确度是调节需求与调节反应之差

B.如调节需求大于调节反应，则为调节滞后

C.近视患者屈光矫正后，视近时常表现为1D左右的调节滞后

D.近视患者屈光完全矫正后，视远时往往可以测得1D左右的调节超前

E.远视患者视近时往往表现为调节超前

答案

参考答案：D

解析：调节超前是调节反应大于调节需求的一种状态，所以近视患者屈光矫正后，视远时如果测得1D左右的调节超前，则提示屈光过矫。

单项选择题

Questions from 36 to 40 are based on the following passage: A garment label is more than just a piece of fabric. It is something that draws the attention of customers to the garment. In today’s times, labels actually help in selling a garment. Customers decide whether to buy a piece of apparel or not on the basis of its label. Labels communicate to the customer what types of materials have been used in making the garment. Different manufacturers use their own special type of labels to create their own distinct identity. A label might be custom-made by a manufacturer to make it unique. Beautiful, customized labels add to the beauty and style of the garment. Each brand produced by the manufacturer is usually distinguishable on the basis of a special symbol, color or word. This is reflected through the label. Garment labels can be made using several fabrics, in different types of finishes and can be attached to the garment in different styles. The fabrics that are commonly used in the preparation of labels are satin, damask, semi-damask and taffeta. In some cases, cotton, canvas and felt are also used in making labels. Satin is the most used fabric in preparing labels. Leather labels are generally used in case of jeans and pants. PVC labels are used in pants and bags. Satin is soft on the skin and looks very pretty initially. However, it is not one of the best fabrics to be used in labels because it is very thin and can snag easily. Labels made using taffeta are stiffer than those of satin and do not snag as easily. However, taffeta labels can irritate the skin of the customers. Damask and semi-damask are ideal fabrics for making labels. Damask labels are soft even after finishing and do not cause any irritation to the customer. Semi-damask is similar to damask in feel, but it costs lesser than damask.

The labels communicate to the customer with the information except（）

A．the material types used

B．the unique style and distinct identity

C．the reasons for purchasing

D．being beautiful and unique
