这种自动调节花盆由四大部分组成一一花盆、太阳能供电器、显示屏、吸水器。花盆壁很厚,有很多层。花盆边上有凹槽,可以将营养液、水、***虫剂倒入里面,花盆可以自动调节每次用量。花盆内壁有红外线感触系统,可以得知土壤的干湿度。花盆底部也有红外线感触系统,还有一些吸水孔,连着下面的吸水器。这所有的电量,都来源于太阳能发电器。太阳能发电先将太阳能转化为热能,再将热能转化成电能,再启动整个机器。即使白天没有太阳,在花盆底部也有一个插头,可以充电。你可以用显示屏来调整整个机器的运行、得知植物的生长情况以及土壤的干湿和温度,有几千种植物信息在里面,即使没有,你也可以在网上查好资料,在显示屏上自己编程序和每种东西的用量。
在这种花盆里种植植物,完全不需要担心。首先,将植物种进花盆内,在显示屏上输入这种植物的名称,系统会在事先已经录入好的资料里找到这种植物的生活习性,并且自动分配好花盆各个部分的工作。你只需要往凹槽里倒入大量营养液和水还有***虫剂,并将花盆放到太阳底下或插上电就好了。这时,花盆就会根据资料,分配水、营养液和***虫剂,通过内壁上的小孔,流入土壤内。这时吸水器的吸水孔是完全关闭的。等土壤全部浸湿后,内壁上的'红外线感应器会将多的水分从吸水孔中排到吸水器里,过滤到内壁里,等下次浇水时再次利用。假如土壤中有虫子,红外线感应器会感应出来,自动喷洒***虫剂,并在显示屏上显示出来,让主人时刻了解植物的生长情况。假如植物烂根了,或者死掉了,红外线感应器会第一时间感应出来,报告给主人。
有了这样的新型花盆,每到节假日,我们只需要往凹槽里加入足够数量的水、营养液、***虫剂,就可以放心的出远门了。有了这样的花盆,我们的城市就会多一点绿色,少一点枯黄,让我们的家园更美好!我相信一定会有那一天!
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 see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。
Nowadays, many famous university campuses have become one of the popular tourist attractions. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. In the place far away from the capital city, the local students also visit the universities famous in their own province.
So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions. On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere.
In my opinion, the tourism to the universities is not a good thing. The campus is mainly a place for study. With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.
首先,提纯范文 “谋篇布局”及结构模板。
第一段:提出问题或现象。Nowadays, … … have become one of the popular … …. It has been shown on TV and on the radio that … ….
第二段:正反列举人们的看法。So far as the present situation is concerned, is it a good or bad thing to … …? Different people have different opinions. On one hand, some people argued that it is a good thing for … … in that … …. On the other hand, some people hold a negative view about this phenomenon. In their opinion, … … will have negative effect on … … because it will not only do harm to … … but also to … ….
第三段:摆明自己观点。In my opinion, … … is not a good thing. … … With the increasing … …, it will ruin … ….
其次,提纯范文“段落写作”。
段落写作分为统一性,连贯性和完整性三方面。
统一性(unity:段落开头的主题句应该做到不可太宽泛,也不可太具体,做到有较强的概括性才能使下文做到有的放矢的展开。范文第二段首句以设问的方式提出一个问题is it a good or bad thing就有很强的概况性。下文自然会一方面从好的方面说明,另一方面从坏的方面说明。
连贯性(coherence:关联词是使文章段落之间相互连贯的必要条件。范文中nowadays, on one hand, on the other hand, in one’s opinion即以“启承转合”递进的顺序是文章条理清晰,层层展开。
完整性(completeness:以设问句“So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists?”开头,这是平时较少运用的段落写作方式——设问法。“On one hand … …. On the other hand, … ….”是段落写作分类列举法的典型用法。
再次,提纯范文“句子写作”。
1. It has been shown that … …
类似句型:It is known to us that … …
It is said that … …
It is reported that … …
It is controversial that … …
2. “… … Tsing Hua University and Peking University and other famous universities … …。”——并列句。并列句是简单的复杂句。但其运用方法并不简单,注意练习并接句的使用,会使句子显的更加饱满。
3. enable v. 使…能够
I gave him full directions to enable him to find the house.
4. in that = because
表“因为”的连词还有since, for, as,如:
The boy was absent because he was ill. = The boy was absent since he was ill.
此句以我们常用的人称开头,句式简单,我们可以通过把since提前改变句式,如:
Since the boy was ill, he was absent. 句式多样化。
最后,提纯范文“措辞”。
1. attraction n. 具有吸引力的事情。
2. thousands and thousands 成千上万的
形容“多”的表达方法:millions and millions
a multitude of
a great deal of
a large amount of
plenty of
many a
3. “some people argued that … …”中的“argue”并不是“讨论,辩论”的意思,而是“认为”。
I argue that … …
I maintain that … …
I claim that … …
I insist that … … = I think that … …
I hold that … …
I assert that … …
I assume that … …
4. negative adj. 否定的.,相反的
hold negative view = hold opposite opinions
5. phenomenon n. 现象
social phenomenon 社会现象
natural phenomenon 自然现象
6. intellectual adj. 聪明的= intelligent, bright, clever
(选词策略:使用最近所学的单词,如intellectual > intelligent > bright > clever
在分析并掌握范文之后,我们需要运用范文知识练习仿写。笔者运用2005年12月范文中的模板结构仿写了2006年12月的四级作文,以供参考:
1. 许多人喜欢在除夕夜看春节晚会
2. 但有些人提出取消春节晚会
3. 我的看法
Nowadays, the Spring Festival Evening has become one of the popular topic and attractions during every traditional New Year’s Eve. It has been shown on TV and on the radio that every year thousands and thousands of Chinese people appear to be accustomed to enjoying the sights and sounds of a brilliant feast, while gathering with their beloved family.
However, an increasing number of people have voiced different opinions towards it. So far as the present situation is concerned, is it a good or bad thing to cancel the Spring Festival Evening? Different people have different opinions. On one hand, some people argued that it is a good thing to amuse the audience in that it is composed by a numerous adequate programs, such as the emotional song, the graceful dance, the funny short sketch, the amusing comic dialogue, the delightful magic, and the marvelous acrobatics and so on. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the Spring Festival Evening will have negative effect on the family harmony because it will not only do harm to having the talks between family members on the Spring Festival Eve but also to enjoying the gourmet meal in a fancy restaurant.
In my opinion, the Spring Festival Evening is a good thing. It may not remain a must for all people, but it can bring us a strong sense of festivity and serve as an alternative among the variety of holiday activities. With the increasing audience of the Spring Festival Evening, it will ruin a distinctive culture during the Spring Festival vacation.

你好啊情绪大王,首先请原谅周周老师在课下偷偷给你取的新代号,但是我觉得这个称号真的是太适合你不过了。你有种特别吸引人的气场,在刚开学的时候就给我留下了极深的印象。
“你为什么站军姿的时候要反复碰身边的小朋友呢?”,你没有直面我的问题反而扭过头朝向委屈的豪豪说,“我只是想让你自己学会解决问题,你怎么就只会报告老师呢?”,可是情绪大王啊,你遇到事情的时候又是怎么解决的呢?
当执勤的小小安全员提醒你在走廊不能奔跑,并且要求你立正站好时你撒腿就跑,和四年级的哥哥姐姐们“据理力争”,然而你并没办法理直气壮,所以你就使出了自己的***手锏,变身情绪大王,进化过程——先微微含胸驼背,继而龇牙咧嘴,然后目光恨恨,接着双手紧握在身体两侧,随着一声长长的吼叫,便开始张牙舞爪,使得身边周围近一米的范围大家都不能靠近,至此,“情绪大王”究极进化完毕。
可是情绪大王啊,这样的解决方式你认为合适吗?每次你变身之后,周周老师都需要顶着你气场的压力,来和你一起慢慢从情绪大王回到可爱的样子。首先,我们都知道,哭不能解决任何问题,这只是一种宣泄的方式,包括挥舞拳头,可是这种暴戾的情绪不利于你的健康成长啊。它只会让你痛苦,让你失去控制,让其他人远离你,不敢和你亲近,所以亲爱的`情绪大王啊,我们需要控制自己体内的洪荒之力,尤其是当别人在帮助我们改正身上的坏习惯时,我们就要虚心接受啊,这样才能成为一个更好的自己啊。
一个学期过去了,你进化的频率和次数都在降低,到了这个新的学期,目前为止一次进化都没有诶,恭喜你啊情绪大王,你马上就要战胜自己体内的小恶魔了。除了昨天的英语课上,你因为别人笑话你,所以将橡皮在短时间内瞄准并且掷出,一个完美的抛物线直接将一个小朋友弄哭了。笑话你的小朋友当然也受到了批评,毕竟我们都知道应该学会尊重他人,不能嘲笑 或者落井下石。但是情绪大王啊,我们遇到事情要先反思自己有没有做好啊,而且你的解决方式也不完美,我们都知道遇到问题不能用拳头了,而是嘴巴,君子动口不动手嘛,不然你每次犯错我都暴揍你一顿,你肯定也不乐意吧,所以将心比心,我们换个角度来替别人思考一下,就可以找到更合适的方法啦!我们可以在课下用讲道理的方法或者通过寻求周周老师的帮助来解决嘛,不要觉得找周周老师会显得自己很没有面子,我可是很乐于主持公正的!不过好在你这次只是处于第一阶段“据理力争”——“谁让他笑我了!”,并没有完成究极进化,而且事后很快认识到了自己错误,我真是替你感到开心!
刚刚课间去班里照常“视察”,你拉着我让我给你讲故事,看着因为刚上完体育课而满头大汗的你扬着一张灿烂的笑脸,我也能感到自己的嘴角也在上翘,“我去喊阅览室的小朋友回来一块听吧!”,我摸了摸你微微湿润的头发,“不用,我今天只讲给你一个人听。”,从书架上拿起你最爱的《三国演义》,蹲到你座位旁,“今天给你讲桃园三结义吧!东汉末年......”“哎呀刘备原来卖草席啊,我还以为是关羽,看来原来看的看来都忘了啊......”
