Scattered through the seas of the world are billions of tons of small plants and animals called plankton。 Most of these plants and animals are too small for the human eye to see。 They drift about lazily with the currents， providing a basic food for many larger animals。
Plankton has been described as the equivalent of the grasses that grow on the dry land continents， and the comparison is an appropriate one。 In potential food value， however， plankton far outweighs that of the land grasses。 One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates each year， the sea＇s plankton generates more than twice as much。
Despite its enormous food potential， little effect was made until recently to farm plankton as we farm grasses on land。 Now marine scientists have at last begun to study this possibility， especially as the sea＇s resources loom even more important as a means of feeding an expanding world population。
No one yet has seriously suggested that " plankton-burgers" may soon become popular around the world。 As a possible farmed supplementary food source， however， plankton is gaining considerable interest among marine scientists。
One type of plankton that seems to have great harvest possibilities is a tiny shrimp-like creature called krill。 Growing to two or three inches long， krill provides the major food for the great blue whale， the largest animal to ever inhabit the Earth。 Realizing that this whale may grow to 100 feet and weigh 150 tons at maturity， it is not surprising that each one devours more than one ton of krill daily。
分布在世界海洋的数十亿吨的小型动植物浮游生物要求。 大多数动植物太小，对人类的眼睛看到的。 他们飘流懒洋洋的潮流，提供了许多基本的食物大型动物。
浮游生物被称为草原相当于生长在干地上大陆，是比较恰当的。 粮食潜在价值，远远大于浮游生物的土地种植。 科学家估计，在全世界产生草约49亿吨，每年有价值的碳水化合物、海洋的浮游生物带来超过两倍。
一类浮游生物，似乎有很大的可能性是很小的收成虾一样东西称南极。 越来越两三英寸长，主要渔获为粮食大蓝鲸，最大的动物都生活在地球上。 实现这一鲸鱼可能增加到100英尺，重150吨，在成熟，这是不奇怪的，每个人的一吨多食海每日。
Now, the degree of urbanization has been deepening and we enjoy the convenience brought by urbanization. How does everybody know how the cities began? Long time ago, the world had only a few thousand people. These people moved from place to place, hunting animals for food. No one knows how or when these people learned about growing food. But when they did, their lives changed greatly.One thing is certain that they gathered in the rich place or near water. In that age, water and climate are the most important to lives. It is the rich water and comfortable climate that gathered people from different places. They began to live near one another, so that the first village grew. Many people came to work in the villages. Then the villages became bigger and bigger.When machines were invented, life in the villages changed again. Factories were built. There were a growing number of people living near factories. Because of the increasing people, more and more buildings were built. And then cities were built.

2。 词汇的学习最困难。如果有人说不，他保证是“唯心主义”。那既然如此，有无捷径？这儿就有一条捷径，穿越时空隧道，到达梦幻之境。词汇的学习要以变应变，在不同的阶段，要有不同的方法。想一想你是如何记住f ace 和pencil的？死记硬背，“无他法，唯手熟尔”（卖油翁）。所以，从原理上来说，词汇的学习离开死记硬背是不行的，因为，外语的学习要点在于记忆，死记硬背好比打基础，离开了他，毫无大厦可言。如果你的词汇量在5 000以下，买一本词汇书，词汇量在3000（背功不行）5000（背功还行）7500（背功很好）。选择标准有三：1。有音标；2 有词性；3 内容简单，没有例句。 你是如何记住facial, surface, deface; acclaim, declaim, proclaim 的？因为你知道-face- ,-claim-的意义。所以，词根词缀法是你学习词汇第二阶段的方法。词根词缀法的意义我就不多说了，你是如何记住flagrant 和fragrant的？因为你知道-l-(一根大棒),-r-(一朵鲜花)，所以他们的意义就井然分明了。联想记忆法是你学习词汇第三阶段的方法。唯有联想，才能强力扩大词汇范围。联想记忆法有时也叫做邪门记忆法，这方面的书很多。
3 . 如何运用词典扩大词汇量。关于辞典。词汇的学习离不开词典，如何选用她至关重要。我做一个Prediction ，70%的人用的是牛津和朗文。但是你如果看一下英语专业的考试大纲的话，你会发现，COLLINS COBUILD 和 WEBSTER’S COLLEGE DICTIONARY 才是最好的工具书。我用的就是后者。为什么要推荐这俩本呢？1、释义详细，简练；2、提高词汇在上下文的理解能力；3、后者还提供词源，方便理解与记忆。

环境日英语作文：The Importance of Trees(树的重要性)
The Importance of Trees
As we all know, trees are very useful. They are of great benefit to man as follows: First, trees provide us with wood and other products; Second, their roots can allow the rain to sink in and keep the soil, so they help to prevent droughts and floods. Trees can clean air and beautiful life.
Unfortunately, nowadays in many parts of the world lots of people fail to realize the importance of trees. They have cut trees down in large numbers without a plan,which makes the soil washed away. They don't know where there no trees, the rain washed away the surface of the soil and this causes floods.
We ought to plant trees each year and carefully look after new trees in order not to make the forest slowly disappear. Only' in this way can we make the forest serve man forever.
高考英语满分作文 Health is More Important-健康的重要性
There are many people who think that wealth is better than health. I used to think so until one day I read a story about Howard Hughes. He was an American billionaire who got anything he wanted. However, in the last twenty years of his life, his health began to deteriorate and he was miserable. He had the best doctors and nurses. However, he could still find no relief. I realized that health is worth all the money in the world. If you have millions of dollars but your health is poor, you will not be able to do what you want to do. So I would like to say don't hurt yourself trying to make money. Instead take care of your body and be happy with what you do have. Health is more important.
很多人都认为财富宫比健康更重要。在读到Howard Hughes的故事之前，我也是这么认为的。Howard Hughes是美国的一个亿万富翁，能得到他想得到的任何东西。但是在他生命最后的二十年中，他的身体变得很糟糕，他很悲惨。他有最好的医生和护士，但仍得不到解脱。我意识到在这个世界上，好的身体抵得上所有的金钱。因为即使你有百万美元但身体糟糕，也不能做你想做的事情。因此我想说的是关心你的身体，对你所拥有的一切感到高兴，不要为挣钱损害你的身体。健康更重要。
Which is more important, health or wealth? It is a hot topic among people. I can hardly answer this question. I didn't realize that health is more imporant until I saw a businessman's real life.
A successful businessman, one of my father's friends, devoted himseff to his business. He works from morning to night every day. There is no weekends in his mind. He often says, "I must earn much money so that I can get what I want. "Lately, he is ill. Though he has a lot of money, he can do nothing but lie in the hospital's bed.
So I think health is more important than wealth. People can do nothing if they are always in poor health, let alone happiness. No matter we are rich or not, we can not ignore the importance of health.
how important is money ?
no one would argue , i think , that money is unimpor tant . there a re ce rtain things that human beings need — food , shelter , medical care and these things cost money . but if one has enough money to live on , to pay for the basic essentials of life , is it impor tant to have a lot more money than that ?will your life improve in propor tion to the amount of money that you have ?
well , there is no denying that money can buy a lot . maybe you do not need much money to pay for a simple shelter , but how about if you want a nice big apar tment in a nice neighbourhood , or if you want to buy a house ? in fact , people do get on each other’s ne rves if they are crowded together in a small kitchen , if a mar ried couple cannot but sha re a room with their parents , if childr en ar e not allowed to have a little privacy of their own .
mor eove r , it is nice to get a little pleasur e out of life, a little fun from time to time . unfor tunately , many of the fun things that you can do today cost money . in modern cities , for example , on any night , outstanding performers appear in night clu bs and on concer t stages . fur thermore , you can dine on foods f rom eve ry corne r of the wor ld in the restaur ants . so how can it be that many people in mode rn cities do not have fun ? simple, they do not have the money to take advantage of all these att ractions .
so , is money the road to happiness ? not r eally . la rge numbers of people work eve ry day , work over time, work weekends , and make a lot of money . are they happy ? no . they have no time to form or maintain friendship , no time to enjoy themselves .
sur ely everyone has thought at times ,“if only i had a lot of money , i would be the happiest person in the wor ld .”but it is impor tant to r emember that money is only a means to an end , not the end itself .
Today is Sunday, it’s my favourite day.
At eight o’clock, we have milk and eggs for breakfast. At nine o’clock, I play ping-pong and football with my father. In the afternoon, I play computer games. Wow! The computer is so interesting. Then I do my homework. In the evening, I read some books and listen to music. At last I go to my little bed and have a sleep.
Dogs belong to the canine.
When a dog follows its nose, it's actually being led by thee key senses. Sight:a glimpse of the enemy saves them barking up the wrong tree. Sound: a bark can be a fierce threat, but it's also how canines make their long distance calls. Smell: this tells a dog more than all the other senses put together.
Inside its nose are around two hundred million smell sensitive cells, forty times more than in humans. Through them the dog's brain can pick up signals from one molecule of scent in a million. It gives the dog: a completely different picture of the world, based on what it smells, rather than what it sees.
Flowers are irrelevant to a dog. So their scent is meaningless. But food is a serious matter. What to us is an empty plate, is covered with the smell of chicken to a hungry dog.
I have a dog. My dog name is DuDu. DuDu is 9 years. DuDu is fat. It wears a white coat. DuDu has two big eyes and two small ears. It has one short mouth. My dog is smart. I like my dog. Do you like it?
My Dog Is Fun I have a cute dog in my home.It is only 1 year old.It is very activity. It always runs in the house and makes noise.when I walk my dog in the park , it usually plays in the grassland and makes itself dirty. So I always wash it when I come back home. In the evening when I do my homework , it stays on my feet quietly. When I finish my homework , it jumps to me to give me a surprise. It is very fun. Do you think so
I’m a dog lover, because dogs are tame, friendly and easy to communicate with. I have kept one in my house, whose name is Chocolate. She is covered with brown curly hair and looks like a Teddy Bear. Now we have been living together for two years, so I’m very familiar with her characteristics. When she is hungry, she often barks loudly. At that time, I begin to realize that it’s time to feed her. She is keen on beef and fish. Sometimes, she also eats some rice.
Every day when I come home, she always jumps up to me happily, with her tail moving. She seems to be my best friend. As time goes by, the relationship between us becomes closer and closer. Therefore, I think her as an important member in my family. I really have the pleasure of her company.
If earthquake happened,firstly,don't panic and calm down.Secondly,find some safe place to stay and don't run in such a hurry.If in the room,one should hide himself/herself under something hard,such as desk,talbe or even bed and keep away from shelf and cupboard,and never take a lift to go downstairs.If in the open air,find an open place and never get close to cars or waterside.Thirdly,because when earthquake happen,there are also lots of other troubles to take place,for example fire.So we should help each other when we meet trouble.At last,no matter how strong the earthquake is,if only we have the belief to defeat it and never give up,we must be able to overcome any difficulties.
