Bid farewell to uncomfortable desk naps! A new national standard has been established to offer students in primary and secondary schools a more comfortable way to rest during lunch breaks. Approved by the State Administration for Market Regulation, the standard (GB/T 46016—2025) will come into effect in February 2026. It aims to make desk-chair sets used for napping safer, more comfortable, and longer-lasting. The regulations cover everything from design and manufacturing to everyday use.

The standard specifies size measurements based on the physical development of students. Desk height should range from 455 mm to 730 mm for primary students and from 565 mm to 790 mm for middle school students. Seats must be no less than 360 mm wide to promote good posture. There should also be sufficient legroom — 110 mm for younger students and 150 mm for older ones — enabling free movement of the legs.

Unlike ordinary chairs with fixed backs, these napping-friendly chairs can recline. When fully flat, each chair must measure at least 1050 mm in length, with a backrest that tilts beyond 135 degrees. A headrest and leg support are also required for improved comfort, allowing students to lie down rather than slump over the desk.

Practical features are also emphasized. Surfaces must be easy to clean — even from common classroom messes like ink or stamp pad stains — with a standard eraser. Moreover, the furniture must meet strict durability standards. Leg supports must withstand 20,000 uses, adjustable mechanisms are rated for over 10,000 cycles, and plastic components must pass 500-hour aging tests.

This updated standard represents a significant step forward in improving students’ rest environment at school. Well-designed napping desks and chairs will help students enjoy better quality breaks, allowing them to return to afternoon classes refreshed and focused.

1.1.What can be inferred about traditional desk naps?

A They were regulated.

B They caused discomfort.

C They improved focus.

D They saved space.

解析：选B。B 推理判断题。首段首句“告别不舒服的课桌小睡！”（Bid farewell to uncomfortable desk naps）暗示传统课桌午休方式令人不适，选项B“引起不适”是基于此的合理推断。故选B。

2.2. What is the primary purpose of the specified desk and seat measurements?

A To enhance classroom aesthetics.

B To reduce production costs.

C To allow personalized decorations.

D To accommodate varying age needs.

解析：选D。D 推理判断题。第二段第一句指出标准基于学生“身体发育”（physical development）制定，后文通过具体尺寸差异（如中小学课桌高度、座位宽度和腿部空间的不同数据）进一步佐证。故选D。

3.3.The underlined word “recline” most likely means the chairs can ________.

A bend backward

B rise up higher

C stand straight

D fall apart easily

解析：选A。A 词义猜测题。根据第三段下文描述“backrest that tilts beyond 135 degrees”（靠背可倾斜135度以上）和对比“lie down rather than slump over the desk”（可以躺下而非趴着），可知recline在此处指“向后倾斜/放平”。故选A。

4.4.What can be inferred about the new furniture?

A It is very cheap.

B It is highly durable.

C It is lightweight.

D It is colorful.

解析：选B。B 推理判断题。第四段指出腿托需承受“20,000 uses”，调节机制需“over 10,000 cycles”，塑料件需通过“500-hour aging tests”，这些严格测试表明新课桌椅非常耐用。故选B。
