今天,我在电视上看到了鲨鱼捕食的情景,这不得不让我想起了“海洋里的猎犬”——鲨鱼。
鲨鱼是海洋中最出色的“捕食专家”,它之所以被人们称为“海洋里的猎犬”,主要在于它的听觉和嗅觉,鲨鱼可以在 1千米以外察觉其他鱼的存在。据真实情报,鲨鱼在地球上生活已超过四亿多年。
鲨鱼的种类很多,有大白鲨、鲸鲨、蓝鲨、虎鲨……其中,最厉害的是鲸鲨,是目前发现最大的鱼类。
但是,由于人类和同类的捕***,鲨鱼也已经快要灭绝,就连刚出生的小宝宝都要被吃得只剩两三只了。
保护我们的“海洋猎犬”——鲨鱼吧!
A tiger is a kind of catamount animal. It looks like a cat, but much bigger than a cat. A tiger is very ferocious and it eats mainly meat. It has yellow and black streaks all over its body and it looks very beautiful. Its tail is long and strong and it can hit its quarry dying.
Tigers live in the thick forests and small animals in the forests are tigers' food.
During the past years, many forests have been cut down and the living conditions of the tigers are becoming worse and worse. There are fewer tigers left in the world now. Tigers are the animals of the world, and they should have their own living spaces. We must do our best to protect the tigers and their living environment.
今天,到酒店吃饭,一进门就看到玻璃窗里摆着一块白色的东西,我问爸爸那是什么?爸爸说是白鲨鳍,也就是大鲨鱼的翅。一提起鲨鱼,我就想到鱼肝油和宴席上的鱼翅汤,还有电影里的大白鲨,要不就是被吃的形象,要不就是吃人的形象。可爸爸告诉我,鲨鱼在不久将来就会从海洋深处消失,很可能会成为因为人类因素而第一个绝迹的海洋生物。为什么鲨鱼会第一个绝迹呢?因为每年人类***掉的鲨鱼数量高达550万只,而真正数量可能还不止这么多。在我们国家,吃鱼翅代表着财富和尊贵,随着人们收入的增加,人们对鱼翅的需求也越来越多,对捕鱼的人来说也是一笔很大的收入。可是,让人难过的是,渔船捕捉到鲨鱼后,因为鲨鱼很大,占据了船舱,而且吃鲨鱼肉的人很少,所以船员只把鱼翅割下来,就把剩下的鲨鱼放回海里,没有鱼翅的鲨鱼不久就死掉了。
另一个严重的问题是,鲨鱼成熟晚,生小鲨鱼的数量少,而且成长速度慢,大约十年才能长成一条成年的鲨鱼。好不容易长大的鲨鱼,却因为鱼翅而失去了性命,所以鲨鱼越来越少了。那,没有鲨鱼有什么问题呢?爸爸告诉我,大自然的生物链是一个紧密相连的系统,如果我们从生物链的一个环里取出一个物种,其他海洋生物就都跟着灭绝了,所以现在很多国家的动物保护学家都提出要保护鲨鱼。保护鲨鱼是一个很新的概念,它不像保护海豚和保护鲸鱼那么容易被人接受,因为人们都认为鲨鱼很大,很凶恶,很喜欢吃比它小的动物,喜欢吃人。事实上,大多数的鲨鱼,很少超过两米,而且,最大的鲨鱼――鲸鲨主要吃虾蟹。
了解了这些信息,下次再看见桌上的鱼翅,我们是不是该好好重新考虑一下,有没有必要为了一时想吃鱼翅,让一个珍贵的物种从地球上消失呢?
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.

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
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.
我原来是一颗快乐的小树苗,被人们栽在了路旁,但我还很快乐。和许多树一起说说笑笑,开心地成长,瞧,我长得多茂盛呢!
可是好景不长,有一天,我的对面开了一家摩托车店,我的后面就是摩托车修理店。一开始,人类还友善地对待我,可是时间一长,他们忽略了我,修好车把什么东西都往我这扔,油和工具是“常客”,阻碍我成长,油使我喝不到清凉的甘露,而工具压得我喘不过气来。
一年过去了,我变成什么样了?天啊,透过摩托车的后视镜一看,乌黑一片,我的叶子耷拉,动辄飘落,甚至也发出难闻的气味,但人类还没有停止,用更“可恶”的方法捉弄我:把摩托车排出的有毒气体朝我喷来,让我熏得只能“苟且偷生”。
我郑重地告诉你们,树木也有生命,如果不是我们为你们输出氧气,你们能得到那么新鲜的空气吗?你们要保护我们,必须!
