“真臭呀!这么多垃圾!”“怎么这么多烟雾，没法走过去啦!”“啊—嚏。”“哎!孩子都快生病了……”行人们议论纷纷，看来，又脏又臭的环境对人们害处可真不小。哈哈!没问题，包在环保机器人身上。
它的头上有红色和蓝色的按扭，背上有红色和蓝色的小背包，按一下红色的按扭，就会把离机器人十米之内的垃圾放入红色的背包，按一下蓝色的按扭，就可以把离机器人十米之内的空中烟雾收尽蓝色的背包里，你一定会想，背包装满了怎么办?不用担心，机器人的头的中央有一根又细又长的针，可别小看这根针，清除废品全靠它呢!它能把所有的废物变成一棵棵茂密的大树，一朵朵飘香的花，或者是清澈的`小河、嫩绿的小草。那双小巧玲珑的眼睛—说出来吓你一跳，能发出一种特殊的光，把离机器人十万公里以内的细菌一下子化为乌有。它的肚子上有许多刺，可以不时地喷出香味，让空气清新。哦!忘记介绍的是：它的两只手心上都有一种名叫吸灰筒的东西，能把汽车尾部排出废气“吞了”，然后把它“吃”了，就可以把这种气体变成电。还有它的脚，踏过的地方都会干干净净，没有一点污渍。
怎么样，给人们的生活带来舒畅的环保机器人还不错吧?

现在我们的社会越来越先进了，许多家长都因为工作太忙，没时间管小孩。上学的小孩没有大人的照顾，上幼儿园的小孩没有大人的陪伴。我想发明一种机器人——保姆机器人。
为什么叫保姆机器人呢?那是因为这种机器人和保姆一样可以干活。
我设计的这种保姆机器人，头部和人差不多，会思考，会说话。身体是一个烤箱，可以煮东西。腿是一把椅子，小孩累了可以坐上去休息。脚是轮子，可以飞快的去一个地方。后脑勺是一台电脑，小孩可以坐在腿上打电脑。它的特点是可以照顾小孩，帮小孩学习，帮大人做家务……我们让它到哪里去，它便会到那里去了。
我是由现在的社会想到的。因为小孩没有大人的照顾可能会变的野蛮。
它可以取代家长要做的许多事情。它可以和孤独小孩一起聊天、玩耍。这样小孩就不会孤单了。
那是一种多好的机器人呀!

我设计的防盗门的外形和机器人一样，机器人的双眼就是我们以前门用来看人的“猫眼”，机器人的手，就是以前门的拉手，他用的是指纹智能板。机器人的嘴，就是用来与外对讲的，里面有一个控制智能板的微型小电脑。工作很劳累的人们，回到家站在自家门前，首先看到的就是机器人可爱的样子，就会很高兴。
我设计的防盗门的内部，都是由高科技的密码控制的。机器的头，就像电脑的主机一样，控制着整个机器人的身体。智能板输入的指纹和微型电脑的记忆，都是由他的头控制的。主人回来了，首先，机器人的眼睛就会变弯，嘴巴就会笑，并说三声“您好！”主人用大拇指一按智能板，微型电脑马上会做出判断。在一秒中之内开门。如果小偷来了，按了指纹，微型电脑发现不对时，那门就会使劲打开，把小偷碰在墙角，然后在一秒中之内恢复原状。
我设计的`防盗门，还有留言系统。主人不在家，有客人来访，客人想留言，便可以在机器人的脚上把主人的电话拨一下，里面就会出现智能板，客人把要说出的话写出来，在恢复原状。主人回来，一按下指纹，机器人的嘴就会告诉主人留言的内容。如果客人和主人想买点东西走了，客人又有急事要出去，客人只要按机器人的鼻子就可以出来了。
嘿！我设计的这种门还可以吧！不久的将来，戴晗博士就会造出来了。

当新学期来临时，许多学生对新生活表现得很兴奋。在大学，新生快乐地享受着自由。在接下来的四年里，他们希望过着高中描绘的'美好生活。但事实是，大学生活中有很多东西要学。
First, the major knowledge occupies the most important role. As a student, learning knowledge is their job, while many students focus on playing cellphone in the class, or just sleep. They lose interest in studying when they come to the free environment. Mastering the professional skill helps them to be competitive. The sad thing is that most of them can't realize it.
首先，专业知识占据着最重要的角色。作为一名学生，学习知识是他们的工作，而很多学生在课堂上玩手机，或者睡觉。当他们来到自由的环境后对学习失去了兴趣。掌握专业技能帮助他们提高竞争力，可悲的是，大多数人没有意识到这一点。
Second, as there is much free time, they can make use of it and gain the valuable experience. Students can join some clubs to develop more interest, or find part-time jobs. It is better than to stay in the dorm and play computer games all the time.
第二，由于空闲时间多，他们可以充分利用好这些时间，并从中获得宝贵的经验。学生可以参加一些活动来发展更多的兴趣爱好，或找份兼职工作。比呆在宿舍玩电脑游戏好多了。
A lot of students feel lost in the campus, because they don't plan campus life well. The things you learn will make you different in the future.
很多学生因为没有计划好校园生活在所以迷失了。所学到的东西会让你在未来有所作为。

Do you ever watch movies from other countries? Whenever I do, I think about how similar people really are all around the world. Even though the cultures and languages in those movies are different from mine, people all around the world are alike in their goals and emotions.
One time, I saw a movie made in china that showed parents helping their children with their homework. . My parents helped me the same way. Another time I saw a movie from Argentina. It showed school children playing hide and seek, which is a game I used to play with my friends during recess. Seeing these films demonstrated to me that education is a common goal in every country. Parents want their children to learn so their lives will improve. It also showed me that children in schools everywhere wants to play with their friends. Sometimes the games are similar to ours and sometimes they’re different. Still, they all have the common purpose of fun and learning to work together.
Earning a living is another common goal. I’ve often seen that in movies about other countries. In some countries, people choose their careers from what they like and are good at. In other countries, careers are chosen for them following the traditions of their families. But in every country it seems that people care a great deal about earning a living, and working hard is respected.
Showing people having fun together is always an important part of any movies, no matter what country it comes from. People everywhere want to be entertained, and want to spend time with their families and friends. Different cultures sometimes enjoy different activities, but all cultures enjoy some form of sports, music and dancing.
The movies I’ve seen make it clear to me that no matter the cultural differences between countries, people everywhere have the same basic needs and goals.

Life has its ups and downs, and only true friends always stay around. Like anyone else, I have got many friends. They often help me when I’m in trouble. Especially, when I fail in an examination, they always care for me and encourage me to study harder. Last year, when I was hurt in a basketball game, my friends took me to the nearby hospital at once and look after me by turns. In my eyes, friends are the most precious wealth that one should treasure all his life.
