This summer my sister and I follow my mother to travel to the United States, we went to the three cities and one island, San Francisco, Los Angeles, Las Vegas, and Hawaii.
Hawaii is my favorite, although only two days, but I went to the beach for several times, is the famous waikiki beach, listening to the tour guide said where the sand came from Australia, where the water is clear, the sand is very clean, when I was in the sea waves to see the small fish, I also into base sand castle on the sand beach, made apple mould sand, crabs, bottle gourd, the shape of a fish, I also want to go to the seaside.
滑翔机由起落架、橡皮筋、机翼、尾翼、螺旋桨等物体组成。先将一根木棍和起落架塞进孔里,再将钩子朝下。然后,从小木棍的尾部推到中间,装上机翼,机翼装成v形并贴稳,最后将尾翼装上,尾翼底部要和一条线对齐。现在并没有完成哦!还要将橡皮筋绕成双重,再将橡皮筋的一头钩着小钩子,另一头钩着尾翼部分的小洞,这样才算完成了。
接下来,我们要将螺旋桨顺时针转还是逆时针转呢?老师说:“如果逆时针转,整个滑翔机向后退;如果顺时针转,将会向前。同学们很好奇,就问:“为什么呢?”沈老师说:“这是伯努利原理。在水中或气流里,速度越小,压力越大,速度越大,压力越小。”王茂羽悄悄的说:“不努力原理。”顾胜凡听到了说:“老师,王茂羽说‘不努力原理’。”我们各个哄堂大笑,肚子都笑疼了。老师说:“我们把‘不努力原理’来读一遍!”王茂羽说:“老师您是不是听多了,所以也喊‘不努力原理’啦,哈哈哈哈!”
下面的时间就是比赛时间啦!我飞得不高只得了个第三名,王茂羽飞得最高。但老师给我们都打了10分。
这堂课是我进入小牛顿科学班的第三堂课,这个滑翔机是我自己亲手制作的。我在这样的小牛顿科学班上,学到了“伯努利原理”、串联电路与并联电路、平衡杠杆原理等许多的科学知识,并进一步提高了我自己的动手能力。当然还有好多的科学知识我还不懂不了解,还有待于去探索去学习。
At noon, grandpa excitedly ran up and told us to go to paradise. I shout of surprise. At noon we eat wonton, even wrapped the wonton to my package so fast so good. I quickly solved the wonton, tidy up the things ready to go.

Last year, I went to Guang Zhou in the summer vacation. I felt so excited, it took me about four hours to get there. In the daytime, the air was so stuffy and the sun was so hot, so my friends and I decided to take a rest in the hotel. When the sun almost got down, we started to go on the street, the first thing was to find something to eat. There were so many delicious snacks, we had no idea which to eat, so we planed to eat as much as we could. I found myself couldn’t stop eating, the food was tasted. After we finishing eating, we started to go shopping.Guang Zhou is famous for the foreign trade, its clothes are fashionable and cheap. We went to the shopping street, trying on all kinds of clothes, at last, we bought many clothes. This trip is so unforgettable to me.去年暑假,我去广州旅游。我感到很兴奋,我花了大约四个小时到那里。白天,空气很闷,太阳很大,所以我的朋友和我决定去旅馆休息。当太阳将要下山了,我们开始逛街,第一件事就是找东西吃。街上有很多美味的小吃,我们不知道吃什么好,因此我们计划尽可能多吃。我无法停止下来,食物太美味了。吃完以后,我们开始购物,广州的外贸很出名,衣服时尚,价格便宜。我们去了购物街,试了各种各样的衣服,最后,我们买了很多衣服。这趟旅程对我来说是很难忘的。
When holiday comes, thousands of people pour into the tourist sites, they want to relax themselves and enjoy the beautiful scenery. But Chinese people have a bad habit, they like to leave some notes on the site, proving them have been here before. Such a behavior has been criticized by the public, because the leaving note will damage the preservation of the tourist site. Most of the tourist sites are part of our country's historical relics, these sites are priceless, it is everyone's duty to protect the sites. When we go to travel, we should behave ourselves. First, we need to have the idea that no rubbish being leaved behind when we leave the site. We should take away what we bring, keep the environment clean. Second, no any notes being written in the sites. Though in the old days, Chinese workers like to leave their names on the sites, but now it is a new world, we need to behave ourselves.
I went to Yunnan Province with my sister to enjoy my summer vacation. During the five-day trip, we visited many famous sites of interest in this province. Among them, Stone Forest in Lunan Yi Nationality Autonomous County leaves a deepest inpression upon me for its strange, steep yet magnificent landscape. Indeed, both my sister and I had such a good time in this tour that we could not help but plan our trip to this province for another time the moment we arrived at home!
