我是纪博士,我正在研究一种高科技的产品──“电脑厨师”。(开篇点题。
“厨师自动化”已不再遥远,只要在“电脑厨师”的“头脑”中放入一张食谱记忆卡片,它就可以准确地自动烹饪出中国、法国或意大利的各式菜肴。下面我向你们介绍一下它吧!
它的体积比一般的烤面包机略大,但却兼具煎、炒、煮、蒸等多种功能,其总重量也不过4.5公斤,在家居狭小的家庭中足以掀起一场“厨房革命”。(简介外形特点。
目前市场上销售的由电脑控制的烤面包机、发面机、电饭锅等都只能算是“低科技”产品,而且它们功能单一,但“电脑厨师”则可以说得上是一件非常精密的厨房高科技产品。它的组合包括一个微电脑处理器、一个小的变速机箱、一个记忆箱、一个记忆卡及一口锅。(简介内部构造。
使用时,只要把所有切好的食物材料装入机器上面的分隔器中,再将食谱记忆卡插入,电脑就可以根据卡中的指示,在适当的时候将食物放入锅中,何时应炒或翻面,什么时候用什么调料,都由电脑控制,只要把材料放好,就可以不管它,过几分钟回来,“电脑厨师”就会给你炒好一道可口的“电脑菜”,你将不必为自己的厨艺太差而担忧。(简介如何使用。
信息加创造等于21世纪。让我们携起手来一起去发明、创造吧!(发感想,发倡议。
老师评价:科技在发展,人类在进步,电脑早已走进了千家万户,但这离作者的愿望还有一段距离,电脑能代替一切人的活动吗?我们还不知道。这篇文章很有创意,能引起读者的探索兴趣,算得上一篇优秀作文哟!
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.
Only by doing like this can you prevent or defeat the A flu in the end.
to prevent H7N9 we should know some common sense. First of all, it is important for us to prevent H7N9 from ourselves. For example, clean our hands frequently.
Sencondly, do more exercises. Such as running. Lastly, change our diet to keep balence. For example, eat more types of vegetables and drink more water
“嗖——”宽阔的柏油马路上一辆豪华的小轿车飞驰而去,停在一座耸入云霄的高楼大厦前,从车里走出一个英俊的男士。这就是我,一个未来的房子设计师——范世杰。我设计的房子既方便实用又环保,很受人们的欢迎,是市场上的抢手货。下面我就给你们介绍介绍我设计的神奇的多功能房子:
这种房子可以变成交通工具。如果一家人外出旅行,它可以变成飞机,环游世界;如果是在海上,它可以变成船或者是潜水艇,欣赏海底美景;如果是在野外郊游,它可以变成一个超级棒的“野营帐篷”。这种房子里还配备有“智能机器人”,你只要按一下微型遥控器上的红色按钮,机器人就会听你的话。你累了,它会给你捶背按摩;你渴了,它会给你拿喝的;你饿了,它会帮你做饭……它还有千万条可以伸缩的手,可以帮你干很多家务。
这种房子能大能小,只要你按一下微型遥控器上的绿色按钮,房子就会变成墨水瓶一样大小,对于搬家简直太方便了。当你要进屋时,按一下微型遥控器上的白色按钮,它又会变成一个能住人的大房子了。
这种房子最大的优点是:吸收二氧化碳,排出氧气,使房子里面的空气非常的清新,冬暖夏凉,四季如春。
听了我的介绍后,你是不是很想拥有一套这样的房子?那么我就从现在开始努力学习,长大后一定要把这种房子发明出来,造福于人类。
老师评价:习作展开大胆想象,设想未来的房子如何具有这种奇特的功能,以适应未来人们的需要。小作者还对未来房子的多种功能展开了丰富的想象,表达了小作者未来事物的美好追求。
想象要大胆,还要合理。要放飞心灵,善于展开奇思妙想。想象要以现实生活为依据,不可凭空想入非非,想象要从客观现实中引出来,想象的内容要与现实社会有联系。“出人意料”,但又在“情理之中”的想象,最值得夸赞。
