To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。
科技是人类进步的桥梁,在我们现实生活中的每个角落,科技产品随处可见。
现在,一个科技十分发达的世纪,所有人都信赖着科技,当然,从衣、食、住、行,以及人的沟通方式都有很大的变化。未来式的变化会更大。
衣,远古时期人们就穿的都是用树上的树叶或者是地下的小草编制的衣服。新中国成立以后,人们就穿的纯棉,皮衣,羽绒,等极其高档华丽的衣服。
食,不必多说。以前人们吃饭都是吃一些窝窝头,再带一些蔬菜,当然,如果生活条件不好时,就会每天忍饥挨饿,甚至有些伟大的父母为使不让自己的孩子饿死把自己所有的食物让给自己的孩子吃,自己一口不吃。而,我们现在,不用说过年过节了,只要我们有金钱就可以买到世界各地丰富的山珍海味,时令蔬菜,新鲜水果。
住,从以前的茅草屋到现在的水泥、砖瓦楼房。以前的茅草屋又矮又小,最多容下两三个人。可现在却不一样了!现在的楼房一栋栋摩天大楼拔地而起,如雨后的竹笋那样比比皆是。
行,最明显不过了。从以前的乡村小马路变成了如今宽阔平稳的水泥路。以前,战争时期能骑上自行的人还真不多。那时只有当官的才买得起。不管是从中国到美国,还是从美国到英国,都是用行驶较慢的火车来运输。而,如今就连我们这样的小学生也不太喜欢骑自行车,别说大人了。对于我们现代人来说汽车,火车,飞机,可真是天壤之别啊。
所有这些变化都是科技进步发展的功劳。
科技的变化全是融入生活中的点点滴滴了,我相信随着科技的发展,我们的生活一定会变得更加幸福美好,祖国的明天也一定会变得更加繁荣富强!
科技发达的令外国人都刮目相看!科技给我们带来了日新月异的变化,我们不得不相信,只要我们努力学习科学文化知识,提高我们的素质,我们的生活也一定会锦上添花!
转眼间,人类社会已经发展成了一个令人惊叹的“多元”社会。它改变了我们的生活,让生活中处处充满了现代科技的气息,比如:智能手机、电脑、电视机、电子计步器、学习机等;就连小朋友的玩具都功能各异:可以一分为三的陀螺、可以手动加速的陀螺、用手抓住都不会停止旋转的爆旋悠悠球。
科技造福了全人类,也使我们的地球变得更加美丽!
一天晚上,我们一家人在一起吃饭,外公望着我给他盛来的香甜可口的米饭,不禁感叹道:“现代科技多么发达呀!你们一定要好好珍惜这美好生活。我们那时,每天能喝到一碗稀粥就满足了,吃树皮树叶的都有呢!现在的稻谷和各种蔬菜、瓜果都种在大棚里,不分春夏秋冬,随时随地都可以吃到营养价值高的食品。”
妈妈也很赞同外公的看法,连忙点头说:“是呀,我们小时候虽然比你外公那时生活条件要好些,但如果饿了,哪还有什么营养食品吃呀,冷干饭泡开水就是我们最喜欢的了。哪比得上现在喝的牛奶都经过了高温灭菌,包装也用的是无菌的。我们当时想喝都喝不着呢!”听了外公和妈妈的一番话后,我也学着用善于发现的眼睛去观察世界,体味生活。
那次,我去爸爸上班的地方――保税商品展示交易中心参观。
一走进大厅,琳琅满目的商品让我眼花缭乱、应接不暇。突然,非洲进口水果展销区吸引了我,也让很多人驻足留连。其中刺角瓜很有意思,外表长得像只金黄色的刺猬,可是果肉却异常细腻、鲜美。还有黄金果,又名五指茄,茄子形的身子下长着五个大“手指”,令我感到惊奇不已。
最让我难忘的是我精心挑选的袖珍南瓜――非洲太阳果。口感面甜,还可以在中间加入冰糖、蜂蜜炖来食用。真是吃到嘴中,甜在心里。擦一擦我那流口水的馋嘴,仿佛自己来到了非洲,再一次让我感受到了时代的变迁和科技的大发展!
同学们,我们在享受科技给我们带来的幸福生活的同时,也要争做科技小能手,好好学习,善于发现和创造,将来为科技的进步,为社会的发展贡献出自己的力量!
How to prevent the H7N9?
As is well known,the A flu is spreading throught our country. However, if we negnect it, the deadly H7N9 may cause more infectors,or even more deaths. So what is the most important is that we should take some effective measures to prevent it.They can be listed as follows.
Firstly,it is necessary for you to realize the Avian flu can be prevented if you develop good living habits. For example,you shouldn’t forget to wash your hands before meals.Besides,don’t spit everywhere and try to cover your mouth or nose with paper or hankerchiefs when you have to cough or sneeze.What’s more, remember to wear the mouth-cover if you have to go to the public places, such as the crowded cinemas,supermarkets, buses,where the A flu may spread easily.
Secondly,of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.
Last but not the least, if you are unlucky to be infected with the slight flu cold, try to stay at home,and take some medicine. Do pay attention to your daily body temperature. If you have a high fever, go to the hospital without delay for further treatment. Make sure you are not expected to come back to school before the cold or flu is cured.

i think students should share some housework with their parents. the reasons are as follows. first, doing some housework can enable the students to have some sense of responsibility. there is a lot of housework in each family. as a member of the family, each one should do his or her share. since a student is a member of the family, undoubtedly, he is of no eception. in the second place, doing some housework can give the student opportunities to get to know his parents better. by doing housework, a student will know how hard it is for his parents to go to work everyday while raising a
family. he will make even greater efforts in his study later on. finally, doing some housework can give the student a chance to do some physicaleercises. since the student has to sit studying most of the time, this is certainly beneficial to his health.in light of the above, i strongly recommend that those who are not in the habit of doing housework start doing some right now. your parents will be pleased and you will learn something from it.
