Summer comes , and the weather has become irritating. My big sister suggested going to Hainan for a good relax. I thought about it for a while and agreed. Hainan is really a good place, where palm trees are abundant.
We went to a park where we enjoyed cool palm drinks. We also went to visit the monkey island. The monkeys were really cute to look at.
After we came back from the travel, we found that our bodies have become stronger and healthier than before. My sister told me that she planned to travel again next year.
We really enjoyed this trip. We were very happy!
I’m going to the sun on my holiday.
I will go there by a spaceship. I will take a big blue spaceshipthen I’ll pilot the spaceship to the sun. the sun is very hot. So I put on the super-shirt. In the morning, I will have some sun burger for my breakfast.At eight o’clock, I will play with my friends there. they are super dog and super girl. Super dog is white and black. Super girl is very clever. Super girl and super dog like to play with me. So I play with them for forty minutes. then I do my homework in my little red room on a small blue table. After my home work, I will have my lunch. I will eat sun salad. I will make some red toy bear to the sun babies. I will have red juice, red fish and red rice. All the things are red. then I need a lot of water on the sun because the sun is too hot. So I will walk to the spaceship.
I’ll pilot the spaceship to the earth
同学们、老师们:
早上好!
今天国旗下的讲话题目是《关注生态环境保护我们的家园》。
在上周五,我们举行了隆重的科技节开幕式,本周科技节的各项活动即将拉开帷幕。老师知道,我们有许多同学已经跃跃欲试,在积极的做着准备。有的同学正在大量阅读着科普读物,汲取科学的`营养;有的同学正在留心观察身边的事物,寻找科技小发明的灵感;有的同学已经张开想象的翅膀,准备用科幻画展现自己美好的理想;还有的同学把爸爸妈妈请来当参谋,指导自己完成科技小制作。老师相信,同学们经过自己的努力,一定会在科技节中展现自己的才华,取得优异的成绩。
科技节里,有非常多的活动等着同学们去参与,其中有这么一项主题活动“保护我们的家园--防止有害生物入侵”。为什么我们要开展这一项活动呢?据介绍,近年来随着我国国际贸易和人员往来的日益频繁,经各种途径有意或无意地将外来有害生物带到国内的事时有发生。据统计,我国每年森林生物灾害的发生面积从50年前的几十万公顷上升到目前的800万公顷以上,其中外来有害生物的危害尤为严重。从上个世纪20年代以来,已经入侵的外来有害生物达数十种,虽然这些外来有害生物的成灾面积仅占整个发生面积的20%,担损失却占60%以上,损失额高达到560亿元人民币。
据不完全统计,目前我国已有松材线虫病、美国白蛾、松突圆蚧等30多个外来入侵动物种和水葫芦、大米草、紫茎兰等90多个外来入侵植物种。特别是松材线虫病等外来林业有害生物的入侵,使我国的森林资源和生态环境受到严重破坏。我们国家每年都要花费上亿元的资金进行防治,直接经济损失也非常大。因此,防止外来有害生物入侵工作刻不容缓,任重而道远。
同学们,我们每一个人有责任保护我们的地球,保卫我们的家园。通过这一次科技节的主题活动,我们可以收集一些有关有害生物的资料,认真听取老师的知识讲座,掌握有害生物的知识,积极参与知识竞赛,开展小调查,写写小论文,找找身边的有害生物,把它铲除掉。还可以开展力所能及的宣传活动,让我们周围的人都来关注我们的生态环境,既要保护有益的生物,如爱护绿化,保护益鸟,消灭有害的生物。
同学们,让我们积极行动起来,热爱我们的家园,保护我们美丽的家园,建设最佳人居环境,让我们在美丽的家园中沐浴着阳光,吸取着营养。
谢谢大家!
