書包，童年的小伙伴你的童年和我的童年好像都一樣，小小的肩膀背上大大的書包，上呀上學堂。當孩子們走進幼兒園的時候，不僅領到了漂亮的園服還領到了可愛的書包，書包是孩子們走進學堂的象征也是孩子們上學的必需品，書包的好壞關系到孩子的健康成長，那么幼兒園應該如何正確選擇書包呢？接下來就給大家科普一下吧！
Schoolbag, childhood friend, your childhood and my childhood seem to be the same, with a big schoolbag on your small shoulder, go to school. When children enter the kindergarten, they not only receive beautiful uniforms, but also lovely schoolbags. Schoolbags are not only the symbol of children entering the school, but also the necessities for children to go to school. The quality of schoolbags is related to the healthy growth of children, so how should kindergartens choose schoolbags correctly? Next, let's popularize science!
01 書包材質要輕便
01 bag material should be light
幼兒園的小朋友們正處于長身體的時候，為了減輕孩子肩部負擔，保護孩子的脊椎，書包應該盡量選擇輕盈的質料，例如可以選擇用牛津面料或尼龍造的書包。此外，應該避免書包有太多金屬扣或金屬拉鏈，因為過多金屬配件除了會增加書包的重量外，也不利于孩子的健康。
Children in kindergartens are growing up. In order to reduce the burden on their shoulders and protect their spine, schoolbags should be made of light materials as much as possible, for example, schoolbags made of Oxford fabric or nylon. In addition, we should avoid having too many metal buckles or metal zippers in the schoolbag, because too many metal accessories will not only increase the weight of the schoolbag, but also be harmful to the health of children.
02 書包肩帶要寬闊
02 the shoulder strap of the schoolbag should be wide
肩帶應該寬闊，有助減低書包對肩膊所造成的壓力，并可以平均分散書包的重量；而備有軟墊的肩帶則可以減輕書包對斜方肌所做成的勞損，假如肩帶過硬，斜方肌便會較易感到疲勞。所以選擇加寬加厚的簡單，釋放孩子肩部壓力，有利于孩子成長。
The shoulder strap should be wide, which helps to reduce the pressure on the shoulder caused by the schoolbag, and can evenly distribute the weight of the schoolbag; The padded shoulder strap can reduce the strain of the bag on the trapezius muscle. If the shoulder strap is too hard, the trapezius muscle will be more prone to fatigue. Therefore, it is simple to choose widening and thickening to release the pressure on children's shoulders, which is conducive to their growth.

03 書包要有調節帶
03 schoolbag should have adjusting belt
有腰帶的書包可以更貼近背部，將書包的重量平均地分散在腰骨和盤骨上面。而且腰帶可以將書包固定在腰部，防止書包搖擺不定，減低脊骨和肩膊所承受的壓力，孩子可以背著這樣的書包盡情奔跑。
The schoolbag with belt can be closer to the back, and the weight of the schoolbag can be evenly distributed on the lumbar bone and pelvis. Moreover, the belt can fix the schoolbag at the waist, prevent the schoolbag from swinging, reduce the pressure on the spine and shoulders, and children can run with such a schoolbag.
04 書包背部軟墊有坑紋
04 the cushion on the back of the schoolbag has pits
由于書包必須緊貼背部，所以背囊的背部應該備有軟墊，而且軟墊應該有坑紋幫助散熱，令小朋友不會汗流浹背，這樣背起來更加輕松自在。
Since the schoolbag must be close to the back, the back of the backpack should be equipped with a cushion, and the cushion should have pits to help dissipate heat, so that children will not sweat, so it is more comfortable to carry.
05 書包的尺寸應該合適
05 the size of the schoolbag should be appropriate
3-6歲的幼兒年幼體弱，知識學習并不多，書本、學具有限，買一個精致小巧的書包足以夠用。同時，精致小巧的書包背在幼兒肩上與幼兒的身形更加協調相稱，也不會讓幼兒感覺不堪重負，影響身體正常發育。所以幼兒園在給孩子選擇書包的時候，應該根據孩子們的體型來給孩子們選擇合適的書包。一個好的書包才能陪伴孩子們快樂成長。
3-6-year-old children are young and weak. They don't learn much knowledge and have limited books and learning aids. It's enough to buy a small and exquisite schoolbag. At the same time, the exquisite and small schoolbag carried on the baby's shoulder is more coordinated with the baby's body shape, and will not make the baby feel overwhelmed and affect the normal development of the body. Therefore, when choosing schoolbags for children, kindergartens should choose suitable schoolbags for children according to their body shape. A good schoolbag can accompany children to grow up happily.
