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!
“儿子,不要再看啦,看这么长时间,眼睛很快就会近视的`!”爸爸换完衣服,又苦口婆心地劝我。但我还是克制不住动画片的诱惑继续看,他又提醒了我第三遍、第四遍,我依然置之不理。爸爸说到第五遍时,声音渐渐变得严厉起来:“我最后再提醒你一遍!我现在数到三,如果你还看,我就把它砸了!”
我以为爸爸只是在吓唬我,继续装作没听见。不料,爸爸数到“三”,见我还没有停下来的意思,二话不说,劈手夺过我手中的电脑,走到阳台拿出锤子,几锤子下去电脑就没声了。我顿时惊呆了,爸爸怎么能这么做?那可是我最心爱的东西!我含着眼泪狠狠瞪了一眼爸爸,跳下沙发,带着满腔愤怒和不解离开了客厅,回到自己的房间,“砰”地摔上了门,并上了锁。
大哭了一场后,我渐渐平静了下来,慢慢意识到爸爸确实是为我好,自己确实做得不对。正在这时,爸爸敲门进来向我道歉,说他不应该发那么大的火。我们父子俩总算是和好了。
人人都会有坏情绪,控制不好,坏情绪还会转化成暴怒。这个时候,就需要我们用足够的理智去面对它,让自己尽快冷静下来,想方设法赶跑坏情绪。现在,我们一家人约法三章,今后再遇到坏情绪,大家要先想一想自己做得对不对,冷静下来后再该讲理的讲理,该认错的认错。你别说,这办法还挺管用的,你也不妨试一试啊!
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.
