An unforgettable travel experienceThere has been a long time since I came back from Hainan—wowhainan is such a wonderful place that I will never forget it .It‘s really a good place where gave me a rather good impression. I feel so wonderful during the journey as I have experienced a lot of things for the first time.In January 7th ---the first day of my journey the fluttering snowflakes diffused over Changzhou. I first took the train to shanghai then took the plane to Hainan in Pudong airport. Although it’s my second time to take plane I felt even more excited than the first time. When flying I found that I was flying over the cloud of different types and colors. The sky is also brighter and clearer than that I had ever seen. Soon we arrived in Meilan airport in Haikou the climate is totally different from that in Changzhou It was warm there and we could see coconut trees everywhere.After 3 days competition I went to BoAo where is famous for its forum. It was my first time to experience the sea and the beach in the sunshine. When sitting on the cruise I could clearly see the ocean waves pushing the windows of the cruise. It seemed that I was surrounded by the waves and the crystal water.
I felt as if a fish which had been living in the sea happily. Then we land on the beach. The sand on the beach was so soft that it was cosy to lie on the beach. I tried searching for the shells on the beach but failed. The beach was totally different from what I heard before as there was nothing except footsteps on the beach. In the afternoon I played football on beach and scored a goal with my new friends from all around China. It was really interesting and challenging.The next day I went to Haikou. I first visited the tomb of Hairui an officer in Qing dynasty who was famous for rectitude. I think he should be the role model of every person. In the afternoon I went to the geological park of volcano. A lot of stones of different shapes came into views. When arriving the top of the park it seemed that the while city was under my view. Also I had seen plenty of interesting and rare types of the plants. I also got into a small hole in the park it is said that the hold was exactly the original hole where maqma came from. But the volcano had stopped from erupting for thousands of years.I can’t forget this trip not only does it give me a lot of joy knowledge and good memory but also it give me a chance to make friends with people from different fart in China. By enjoying the excellent scenery I think I have fallen in love with this beautiful city. I will cherish this experience.

现在的生活越来越好，自行车变汽车，平方变大厦，可在这繁荣的景象中，去有着一些不和谐：汽车排气管排出的二氧化碳，人们还乱砍滥伐数目，森林变成了沙漠，没了树，空气怎么能新鲜的起来呢？
我看到这种现象不是一次两次了，我决定长达一定要发明两种机器，一种叫作树木回收器，他都是纳米做成的，大约有词典那么大，晚上还可以发光呢。它不但好看，而且实用。只要是木制用品都可以变废为宝，比如说把三张废纸放入入口处，再按下“纸”这个键，不到10秒钟，就可以变成一张白纸了，如果你放一个不要的木质笔筒，按下“笔”这个键，经过处理就变成了两只铅笔，当然还有许多功能，如：木筷变纸，木椅变成笔筒等。
我的第二个发明是二氧化碳吸收器。虽然这台机器只有巴掌大，但不要小看它哦！它采用的也是纳米，里面的器材都是废品，但加工一下，它就可以放在汽车的排气管里，堵住它，再接接下红色按键，你发动汽车，它也开始工作了，它前面有两个小口，专门吸收二氧化碳，后面也有两个小口，是经过吸收二氧化碳中的氧气再排放出去。而且用它车也没有发出噪音，使用完后，把它放到树下，按下绿色按键，他就会排放二氧化碳给树吸收，二、三分钟后便排放完毕，而且还吸收了许多氧气呢。放在家里按下黄键，可以放出氧气，也可以减少衣物的碳排放量。
这两台机器很好吧，让我们用双手多做些低碳机器，让生活变得更美好。

我翻了很多书，请教了无数科学家，终于研制出了能识别真假商品的眼镜。外壳跟其它眼镜没什么两样，里面却有复制、警报、辨别和储存、听音装置，将物品复制到眼镜内部，然后传入辨别装置中，大概需要5至10秒，就能辨别出来，接着传入警报、听筒，最后才知道是真是假，如果是真，将会放出动听的歌，如果是假，那么就会响起“叮铃铃”的'警报声。
我试用了一下，没想到发生了意外：辨别了之后响声一直不停，我想：不行，得改一改。
我又请教了许多专家，最后在听筒响声中设定了1至3分钟，再加上了开关，这样耗电率小了，也不会一直响了。
我再次试用，又出现了意想不到的效果：不管这物品是真是假，总也听不到一点声音，我想是电池用完了吗？我换了一节电池，还是不见效果，是听筒坏了吗？于是我仔细地检查了听筒，还是没有问题，难道是线路故障，我耐心地检查了线路，果然是导向出现了故障，我换了一根导向，工夫不负有心人，试验成功了。我拿到国家专利局申请了专利，国家批准了上市，我拿到市场去销售，受到了广大用户的喜爱，商家也不敢卖假货了，从此再也没有假冒产品了，我高兴极了！
在我使用的过程中，也出现了尴尬的事情，一天我和妈妈一起到阿姨家，我戴着这个眼镜，当看见阿姨时，它开始报警，我告诉妈妈，阿姨是假冒的，妈妈生气地教育我：“小孩不要乱说话”。我委屈极了，难道我的产品失败了吗？在回家的路上，妈妈告诉我说，阿姨原来做过美容手术：眼睛是割了双眼皮、进行了隆鼻、纹眉。原来阿姨的美貌是假的。
“吃饭了”妈妈的亲切的叫声打断了我的美梦。

同学们，你们未来想发明什么？飞碟？太阳能汽车？我想发明可以自己把地上的垃圾“吃”进去的垃圾桶。这样，就算人们把垃圾扔在地上也不会污染环境，很环保。（可你们千万不要故意把垃圾扔在地上哦！）
这个“神奇垃圾桶”虽然是个垃圾桶，可它不管是大人还是小孩，人见人爱，可爱到你都想和它合影了呢！“头”上有一对半圆形的小耳朵；一双眼睛炯炯有神，十分惹人爱；大大的嘴巴喊着新奇的环保口号；身体就像个椭圆形的球球，总之，它是个可爱的家伙。
“神奇垃圾桶”不仅可爱，而且作用也很大。它能把地上的垃圾吃掉，并排放出香味和氧气。不过，有些人可能会把垃圾都到垃圾桶上面，别的垃圾桶没办法，只能无可奈何地“站”在那里，可“神奇垃圾桶”会生气，伸出机械手就把你拉住了，让你改正错误。
我想，如果将来我发明了“神奇垃圾桶“，一定会在全球广泛使用。
