关于蚕的营养价值英语作文
One day in April this year,my mother brought me some silkworm babies.This really makes me happy.You should know that China is a world-famous silk country,of which Suzhou and Hangzhou are the most famous.But as a native of Suzhou,I'm a big girl in a sedan chair for silkworm breeding--this is my first time!
The next day,our family went to grandma's house for dinner.After dinner,we went to the back of the house to pick mulberry leaves under the leadership of grandma.We picked a big bag before we went back.
After returning home,I found some black things and some yellow things similar to"shells"in the silkworm rearing box.My brother-in-law,a monk,was puzzled,so I went to consult my mother.Mother said that those black things were the excrement of the silkworm baby,and the"shell"I said was the skin shed by the silkworm baby.Mother also told me that the medicinal effect of silkworm is to accelerate the body metabolism,reduce blood lipids and blood pressure.Silkworm is rich in nutritional value.It is rich in amino acids,proteins and vitamins,which can increase the intestinal peristalsis ability,promote the discharge of wastes in the body,and prevent cardiovascular and
cerebrovascular diseases.It is also rich in iron ions,calcium ions and other substances,which can regulate anemia or hypocalcemia.
I suddenly realized.
We take the baby silkworm off the old leaf and put it on the new one.The first time I touched silkworm babies,I felt that their bodies were so soft.Upon careful examination,each silkworm baby's body has nine bars and seven pairs of feet.There are three consecutive pairs of feet under the head,two bars apart,and four consecutive sections behind.Each section of the body has a pair of feet.There is also a pointed convex object on the tail,like a receiver.
At my mother's suggestion,I carefully observed how silkworm babies eat mulberry leaves.Look,most of these little guys start to bite from the edge of mulberry leaves.I guess it's easy to bite at the edge;However,there are also a few different ones.They start to eat from the middle of mulberry leaves to the surrounding.According to my observation,these silkworm babies eat mulberry leaves in a neat and uniform manner,which is similar to my usual eating watermelon,in a circular arc.
I think it's time to let the baby silkworms rest.At this time,I was surprised to find that a baby silkworm was shedding
its skin.I saw that it pushed its body forward first,and the yellow skin immediately shed more than half,but the rest seemed not so smooth.When I wanted to help,my mother stopped me and told me that the silkworm baby would find a way to shed its skin.I was still in a hurry,but the silkworm baby gave me a surprise.It was close to a mulberry leaf and successfully completed its transformation with resistance.After molting,the silkworm baby's body is whiter than before.My mother told me that the silkworm baby must undergo several molts in his life before he can become a white and fat silkworm girl.
Under the careful care of our family,the silkworm babies grow very fast,as if they were blown up with wheat straw.Mother said:"son,the biggest silkworm babies will cocoon in a week!"This news has excited me for a long time.I can't wait to see this day.
Silkworm babies are like children.Watching them grow up gives me a great sense of achievement.Sericulture gives me infinite happiness and makes my life rich and colorful!

今年4月的一天，妈妈为我带来了一些蚕宝宝。

这可把我给乐坏了。

要知道，中国是举世闻名的丝绸大国，其中以苏州和杭州最为著名。

可我身为一个苏州人，对养蚕却是大姑娘上轿――头一回呢！
第二天，我们一家去外婆家吃饭。

吃完饭，我们就在外婆的带领下，到屋子后面去采桑叶。

我们足足采了1大袋子才回去。

回家后，我在养蚕的盒子里发现了一些黑黑的东西和几个黄黄的、类似于“壳”的东西。

我丈二和尚――摸不着头脑，便去请教妈妈。

妈妈说那些黑黑的东西是蚕宝宝拉出来的屎，而我说的“壳”则是蚕宝宝蜕的皮。

妈妈还告诉我：蚕的药用功效是加快身体代谢、降低血脂和血压。

蚕的营养价值比较丰富，里面富含了丰富的氨基酸和蛋白质以及维生素，能够增加肠道的蠕动能力，促进身体内废物的排出，对心脑血管疾病也有预防的作用，而且其中也富含了铁离子和钙离子等物质，对于贫血或者是低血钙等具有调节的功效。

我这才恍然大悟。

我们把蚕宝宝从旧叶子上拿下来，再放在新的叶子上。

我第一次摸蚕宝宝，觉得它们的身体是那么的柔软。

仔细端详，每条蚕宝宝的身体都有九小节，七对足。

头部下方连续三对足，空开两小节，后面连续四节每节身体各有一对足。

尾巴上还有一个尖尖的凸状物，像接收器。

在妈妈的建议下，我仔细地观察蚕宝宝是如何吃桑叶的。

瞧，这些小家伙大部分从桑叶边缘开始咬，我猜想，边缘处容易下口；但也有少数与众不同，从桑叶中间开始向周围进食，据我观察，这些蚕宝宝吃桑叶的动作整齐划一，和我平时啃西瓜可有一拼，呈圆弧状来回循环。

我觉得已经打扰蚕宝宝很久，是时候让它们休息了。

就在这时，我惊奇地发现一条蚕宝宝正在蜕皮，只见它先把身体往前蹬，黄色的表皮顿时蜕了一大半，但剩下的似乎没那么顺利。

当我想伸手帮忙时，妈妈制止了我，并告诉我，蚕宝宝会自己想办法蜕皮。

我还在着急着，但蚕宝宝却给了我惊喜。

只见它靠近一片桑叶，凭借着阻力成功完成蜕变。

蜕皮后的蚕宝宝，身体比之前白净一些。

妈妈对我说，蚕宝宝一生要经历几次蜕皮，才能蜕变成白白胖胖的蚕姑娘。

在我们一家的精心呵护下，蚕宝宝长得很快，好像是用麦秆吹大的。

妈妈说：“儿子，最大的几条蚕宝宝，过一星期就要结茧啦！”这个消息让我兴奋了很久，我已经迫不及待地想看到这一天啦。

蚕宝宝就像孩子一样，看着它们长大让我成就感爆棚。

养蚕给了我无限的快乐，使我的生活变得丰富多彩！。
