我们应该怎么写这类型的作文呢？下面是小编为大家收集的描写课桌说明文，希望对大家有所帮助。
描写课桌说明文篇1今天上午，吉老师一脸神秘地说：“今天，我向大家布置一个任务：给桌子洗脸!”我们都丈二和尚摸不着头脑：桌子哪有脸啊?怎么给它洗脸?吉老师怎么唬弄人哪!教室里顿时炸开了锅，同学们议论纷纷，有的说：“桌子哪有脸呢?”，有的迷惑不解：“给桌子洗脸?吉老师这葫芦里卖的什么药呀?”我也一脸迷茫。
这时，机灵鬼吴战大声喊道：“哈哈，我知道了!不就是洗桌子嘛!”我一听，哈，对了，就是洗桌子，把桌子擦干净嘛!大家也都恍然大悟地点了点头。
既然是任务那就必须干，而且必须认真干好，于是我们便热火朝天地忙起来了。
我低头一瞧自己的课桌，顿时脸红得像个熟透了的大苹果，恨不得找个地缝钻进去。
瞧，上面有英语单词“windows”，有因为懒不愿意拿草稿本出来，所以在桌上写的数学算式，有汉字“卑”，还有一小摊墨水已经干了粘在上面。
我再扭头一看同桌陈海波的桌子，“哇噻”，他的桌子比我的更赃!他的桌子上黑墨水与黄桌面粘在一块儿，仿佛有许多大伤疤，简直就像一块补着黑补丁的黄衣服。
我的天呀，这个任务布置得真及时，我得赶紧把这些污渍洗掉，太赃了!我朝四周看了看，同学们都卷起袖子，动手了，他们个个都埋头苦干，我也不甘落后，心想：要洗桌子，当然要用抹布了!于是我急匆匆跑到水池旁，可惜来晚了，仅有的几块抹布早被别的同学拿走了!这可怎么办呢?我脑筋一转，突然盯着课桌上放的那块铅笔橡皮。
哈，有了!我可以拿橡皮擦呀!好主意，我拿起橡皮，不管三七二十一，立即使劲儿擦了起来。
“擦擦擦”、“擦擦擦”，我用劲力气，橡皮擦出了许多黑屑子。
擦了老半天，我的手心都渗出了汗，可是由于墨水在桌子上时间太长了，颜色擦淡了，可擦不干净呀!用铅笔橡皮擦太费劲了，我得重想一个好方法!咦，铅笔橡皮擦不了墨水，用钢笔橡皮不就行了吗?我迅速从笔袋里掏出钢笔橡皮，左三下右三下，不停地擦着，手都擦疼了。

The chassis has angle adjustment for tilt in space supporting various postures. All adjustments can be made safely with the child in the seat.Push handles allow the chair to be easily moved around thehome or classroom.The adjustability of the Mygo seating system provides clinicians with the tools to maximise: Pelvic stabilityTrunk and head alignment Leg and foot positioning“Seating systems are aimed at providing an appropriatelevel of postural support for each child, as well asoffering comfort, skin protection and stability to enabledaily functional activities to be carried out at home andat school. As postural control is a pre-requisite for mostfunctional tasks, the inability to control posture has asignificant impact on function” (Wright et al, 2010).Wright C, Casey J, Porter-Armstrong A. Establishing Best Practice in SeatingAssessment for Children with Physical Disabilities using Qualitative Methodologies.Disability and Rehabilitation: Assistive Technology 2010; 5(1):34-47.Posture, Function & Comfort Pelvic stabilityThe most important feature of any seating or mobilitysystem is its ability to provide pelvic stability (for tilt, rotation and obliquity) as this gives the optimum base for trunk and head alignment and upper limb function. The Mygo Seating System has a range of unique features to support the pelvis for each individual’s postural needs.PELVIC STABILITY CHALLENGESPosterior pelvic tilt Pelvic rotation Pelvic obliquity Alignment4-point pelvic harnessThe multi-adjustable 4-point pelvic harness on the Mygo Seating System ensures stability of the pelvis by providing support across the anterior superior iliac spines (ASIS).The 4-point attachments (two at the hip guides and two at 90º) mean that the harnesses stay in the correct anatomical position.Pelvic cradleThe Mygo Seating System can also be fitted with the pelvic cradle. The flexible adjustment in the back section can encourage a posteriorly tilted pelvis into neutral alignment, and the overall design prevents users sliding forward. This gives unsurpassed proximal pelvic positioning and support for more complex body shapes. Where pelvic mobility is reduced, and tilt, rotation or obliquity need to be accommodated, either harness, along with the hip pads,can successfully stabilise the pelvis in these unique positions.HARNESSING FOR PELVIC STABILITYPOSTURESACRAL SUPPORT AND CUSHIONING FOR PELVIC STABILITYIntegral to the Mygo Seating System’s pelvic harness is the flexible sacral support and hip guides. The flexible sacral support adjusts either to encourage a lumbar curve (neutral pelvis) or accommodate a posteriorly tilted pelvis.The hip guides provide lateral pelvic support, and encourage a midline position, but can also accommodate asymmetry by being off-set whenneeded. The generous seat cushion allows immersion of the ischial tuberosities, helping to prevent their forward excursion and providing pressure relief. Additional pads can be used to increase the ramping under the femurs when necessary.The pelvic seat depth (seat back to gluteal crease) can be adjusted from a point on the seat which correlates to the position of the ischial tuberosities. As we rotate about the ITs, this means the lateralsupports stay in the correct anatomical position when the seat back is reclined, ensuring the best possible stability. The pelvic seat depth can be adjusted asymmetrically in order to accommodate a fixed pelvic rotation, along with the sacral support and backrest which can also be angled independently.Comfort is integral to sustaining a functional posture as itreduces unwanted movement which can occur when children are uncomfortable. The new 2010 Mygo Seating System has a 50mm one-piece seat cushion which consists of a single layer of new reflex foam which provides excellent pressure distribution. It allows immersion for the ischial tuberosities to aid pelvic stability as well as providing comfort and maintaining skin integrity. Additional high density foam can be simplyadded under the cushion to accommodate pelvic obliquity or to prevent bottoming out under the ischial tuberosities or femurs.Where it can be achieved, the optimum position of the pelvis for function is in neutral or slight anterior tilt. This pelvic position allows the spine to adopt its natural lumbar, thoracic and cervical curves, aligning the trunk and balancing the head. In turn, when the body is well supported, it maximises the potential for upper limb function for playing, feeding etc; improves opportunities for social interaction; and maximises breathing and digestive capacity.FUNCTION & COMFORTPosture, Function & Comfort Trunk and Head AlignmentSeating systems need to provide appropriate trunk and head support because this contributes to thestability of the pelvis, and facilitates upper limb function, concentration, and social interaction. The Mygo Seating System’s trunk and head supports can be individually tailored to match the needs of each user.TRUNK AND HEAD ALIGNMENT CHALLENGESKyphosis Lordosis ScoliosisThe Mygo Seating System’s flexible sacral support allows the sacral and lumbar regions of the spine to be supported or accommodated whether the spine is kyphotic or lordotic. The sacral supports on the Mygo Seating Systems are also able to rotate, giving proximal support to those with a fixed pelvic or spinal rotation.Flexible scoliosis can be managed by using the lateral supports in conjunction with the pelvic harness to provide 3-point positioning.The seat to back angle on the Mygo Seating System opens to 115º, and when used in conjunction with the lower leg guides, ensures that even when hamstrings are very tight, an appropriate seating posture can be achieved.Where additional chest support is required, the Mygo Seating System has a trunk harness and a cushioned chest support.TRUNK SUPPORTPOSTURE115°Pelvic stability and trunk alignment are the basisof head control. However when additional head support is needed, the Mygo Seating System is fully compatible with the full range of Leckey asnd Whitmyer head supports to meet each individual’sneeds.HEAD SUPPORTSDYNAMIC BACKRESTThe trunk harness has detachable shoulder fastenings to allow increased use of upper limbs.Communication is a vital, but an often overlooked aspect of seating systems. The Mygo Seating System has a seat base to which communication devices can be easily attached. Used in conjunction with the appropriate head support, communication for those using augmentative devices is simpler than ever.As with pelvic stability, the ability of the trunk and headsupports to provide a secure position is central to sustaining optimum posture for function. With cushioning and trunk supports made from soft, comfortable materials, the Mygo Seating System ensures that trunk and head stability and comfort are perfectly combined for maximum function.All Leckey Hi-low bases come with tilt-in-space as standard and can be used to further align the trunk, shoulder and head over the pelvis, or simply allow a change of position for pressure relief and comfort. In addition to the Hi-low chassis, height adjustable arm rests, and cushioned activity tray ensure playing and feeding can be encouraged at home or at school.With the addition of the contoured shoulder section on the Mygo, not only is the height of the backrest extended for greater growth, but shoulder protraction is facilitated for better trunk alignment, upper limb function, and neck and head stability.Leckey now offer a dynamic backrest option for the Mygo Seating System for children with extensor patterns. Leckey is carrying out research withStrathclyde University including long term field trials which will provide evidence of the clinical benefits of dynamic backrests. Available in 100N and 150N it is available on new Mygos or can be retrofitted onto existing Mygos.FUNCTION & COMFORTPosture, Function & Comfort Leg and Foot PositioningSeating systems also need to provide appropriate leg and foot support as this plays a crucial role in maintaining the stability of the pelvis, and therefore the alignment of the trunk and head. Often overlooked, hamstrings are frequently tight in those with limited movement and can disturb pelvic stability. In addition, the feet take up to 19% of body weight, and when unsupported can add to pressure and pelvic stability issues. The Mygo Seating System’s pioneering leg and foot supports enable the child’s legs and feet to be supported in a wide range of positions.LEG AND FOOT POSITIONING CHALLENGESWindsweeping Real leg length discrepancyApparent leg length discrepancy caused by fixed pelvic rotationTight hamstringsThe Mygo Seating System has innovatively designed leg guides which can be independently adjusted to accommodate 10º of windsweeping to the left or right on the smaller seat base and 30º on the larger base. The leg guides can also accommodate adduction and abduction. Offsetting the hipguides to the left or right gives additional space to accommodate a more extreme windsweeping.The Mygo Seating System’s leg guides adjust independently to accommodate leg lengthdiscrepancy caused either by varying femur lengths, or a pelvic rotation presenting as an apparent leg length discrepancy.LEG GUIDES AND FOOT SUPPORTSPOSTUREThe Mygo Seating System’s lower leg supports follow the leg guides when they move into adduction or abduction, ensuring the footplates remain in position below the knees.The footplates can remain in position when the leg guides are extended, allowing the feet to be positioned behind the knees. This alleviates the strain on tight hamstrings which would otherwise pull the pelvis into posterior tilt, and affect trunk and head positioning.Footplates can also be adjusted into plantar ordorsiflexion, and with the addition of sandals,can accommodate foot rotation. If sandals aretoo restrictive, ankle huggers can be attacheddirectly to the foot plates for foot positioning.When legs and feet are appropriately accommodatedto allow the pelvis to remain stable, trunk and head alignment can be more easily sustained because the user’s weight is evenly distributed across the seat surfaces. In turn, when the body is well supported, it maximisesthe potential for upper limb function for playing,feeding etc; improves opportunities for social interaction; and maximises breathing and digestive capacity. Comfort is not just achieved through cushioning,but through matching the individual’s body measurements and angles to the seating system. Accommodating the position of the legs and feetwill add to the comfort, and therefore the functional abilities of the user.FUNCTION & COMFORT12The standard product includes: Seat base BackrestChassis interfaceHi-low chassis Indoor only.4” castorsFoot pedal (gas)Foot pedal (hydraulic)Powered Hi-low chassis - Indoor / Outdoor Foot pedal operated.12” backwheels 5” castorsFoot pedal (gas)Foot pedal (hydraulic)PoweredInterface AInterface Bfor Discovery 400mmInterface Cfor Discovery 360mmSeat ShellEach cover pack will include the Backrest cushion Sacral cushion Orange Blue PinkGreySeat shell Size 1Seat shellSize 2Rigid lateralsIncludes covers (one colour)Rigid laterals extended height Flat headrest & cushionFlat headrest laterals & covers Headrest plate(To fit Otto Bock headsupporthardware mounts SK030 & SK035)Head support bracketfor ½" and 15mm box sectionsArmrests Size 1Armrests Size 2Dynamic backrest with 100NDynamic backrest with 150NSmall trunk harness Medium trunk harnessLarge trunk harnessChest harness1” Spacer pad with lateral supports1” Spacer padFlipaway lateralsIncludes covers (one colour)Shoulder support hardware Shoulder support cushion+07 Orange +08 Blue +09 Pink +06 GreenContoured headrest & cushion (wide)Footplates Size 1Footplates Size 2Sandals (Includes straps) small Sandals (Includes straps) medium Sandals (Includes straps) large1” sandal riserObiliquity ramp kitKnee pads (one colour)TrayGrab railsPadded tray insertPelvic spacer pads Pelvic cradle size 0Pelvic cradle size 00Hip laterals Pelvic harness smallPelvic harness mediumEstablished in 1983, Leckey is a globally recognised pioneer in the research anddevelopment of products that help adults and children with disabilities to go, do, enjoy and participate in everyday activities throughout the day and night.We take a highly clinical approach to product design and development.

关于课桌自述说明文作文7篇
关于课桌自述说明文作文7篇作文是经过人的思想考虑和语言组织，通过文字来表达一个主题意义的记叙方法。
接下来由小编为大家整理出课桌的自述说明文作文，希望能够帮助到大家!课桌的自述说明文作文篇1我是一张课桌，长得方方正正、可高可矮。
起初，我崭新光亮，平平整整，脸上油光水亮，一丝痕迹也没有，站在教室里，稳如泰山，不摇也不晃。
随着时间的推移，我也慢慢地变化，最后不复当初的风采。
早上，我有点兴奋地迎来了我现任的主人。
主人一来，先把我的脸擦干净，又把我的肚子填满了：许多书、本子和文具都一一地躺进了我的肚子里，接着我的脸上也躺上了书和笔，然后，主人坐在我的身旁，双手放在我的脸上，给我带来了一丝温暖，好舒服啊!上课了，我听着老师的声音，陪着主人静静地站着，听主人回答老师的问题，真好听啊!放学了，我看着主人头也不回的背影，有些难过——唉，又要度过一个寂寞的夜晚，幸好，我还有同样寂寞的同伴在身旁陪伴，我无比盼望着天早点亮。
调座位了，我又换了新的主人，我一样地高兴，依然静静地陪着主人上课。
……时间流逝，我的主人不停变换。
有的主人很喜欢我，一来就把我收拾地干干净净、漂漂亮亮，我昂首挺胸、骄傲地站着;有的主人很讨厌我，在我的脸上乱涂乱画，或是拿刻刀在我脸上留下深刻地伤痕——好疼啊，我瑟瑟发抖。
一天一天过去了，一年一年过去了，我迎来又送走了一个又一个的主人，慢慢地，我年纪大了，牙齿松了，颜色掉了，身体不平整了，脸上越来越脏，凹凸不平，站也站不稳了，摇摇晃晃地，一碰就要散架，我的主人越用越不舒服，没有使用的价值了，所以，学校换掉了我。
我最后望了一眼我呆了一辈子的教室，和同我一样被换掉的同伴一起，摇晃了一下：“咯吱”——再见。
我老了，该退休了。
课桌的自述说明文作文篇2我随处可见，无论是教室，还是家中，都有我的身影。
你能猜到我是谁吗?没错，我就是——课桌。
我的妈妈是一棵拥有一百多年历史的槐树，而我，则是一棵刚过五岁的槐树。
那可恶的人类把我砍了下来，后来，把我送进了加工厂，加工成了一张桌子，被送进了教室。
