+ 加入清单

Recently, the haze weather has increasingly been serious and this

phenomenon triggers the widespread concern towards air quality. In my view of

the point, the best way to improve air quality is to tax the owner of private

car.

There are reasons accounting for my view. To begin with, there is no

denying that gas emission of private car is a great evil of air pollution.

To tax the owner of private car will make some contribution to cut down gas

emission and improve air quality. Furthermore, the tax also has a great impact

on decreasing the rate of car’s increase. Those who have a plan to buy a car

will take the tax into account and some of them have to give up their plan. If a

lot of people can use public transportation instead of private cars, the air

quality will not be so rotten. In addition, taxing for private car is also a

warning of environment protection. The notion of environment protection will be

brought to public again and an increasing number of people will be awake to the

importance of air protection and environment protection and make effort to

protect it. Finally, the government can use the tax as funds of improving the

air quality, which will be a great help to raise fund.

Taking above into account, I believe that taxing the owner of private car

is the best way to improve air quality. Certainly, we can carry out other

methods to improve it at the same time, such as planting trees, developing

public transportation and so on. I advocate that all of us should take pains to

protect our environment and we will lead a better life.

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 dont 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.

Different people have different career outlooks. Some people want to become civil servants; some people hope to start their own business; some people dream of being freelancers, and so on.

不同的人有着不同的职业愿景。有些人想要做公务员,有的人想自己创业,有的人梦想成为自由职业者等等。

However, my ideal job is teaching. Firstly, I’m told that teachers have a high income. With the high income, I can open a training school to help the children in poor families with their education. Secondly, teachers always have summer and winter holidays, thus I will have more free time to relax myself. More importantly, teachers are angels to students, who can pass on the knowledge to students as well as help them develop their hobbies and interests. I can’t imagine how happy I will feel when I see my students become elites.

然而,我的理想是教书。首先,我被告知老师的工资很高。若有很高的工资,那我就能开个培训学校来帮助那些贫困家庭的孩子。第二,老师有着寒暑假两个长假期,如此我将有时间放松。更重要的是,对学生来说老师就是天使,传授孩子们知识帮助他们培养自己的兴趣爱好。我无法想象如果我的学生都成为人才,我会多么的开心。

In order to be a qualified teacher, I should read more books to acquire more knowledge, and train my patience and improve my communication and handwriting abilities.

为了成为一名合格的老师,我会读更多的知识从中汲取更多知识,锻炼自己的耐心,提高自己的交际能力并提高自己的书写水平。

Between the darkness of earth and heaven she was burning fiercely upon a

disc of purple sea shot by the blood-red play of gleams; upon a disc of water

glittering and sinister. A high, clear flame, an immense and lonely flame,

ascended from the ocean, and from its summit the black smoke poured continuously

at the sky. She burned furiously, mournful and imposing like a funeral pile

kindled in the night, surround-ed by the sea, watched over by the stars.

A magnificent death had come like a grace, like a gift, like a reward to

that old ship at the end of her laborious days. The surrender of her weary ghost

to the keeping of stars and sea was stirring like the sight of a glorious

triumph. The masts fell just before daybreak, and for a moment there was a burst

and turmoil of sparks that seemed to fill with flying fire the night patient and

watchful, the vast night lying silent upon the sea.

My father is a hard-working man. He works as a doctor. He always tries his best to help every, patient and make patients comfortable. But sonetimes he works so hard that he can’t remember the date.

My mother is a woman with a bad memory. She always does a lot of housework, but sometimes she makes mistakes out of carelessness. For example, one day, she washed clothes in the washer, after the washer finished the work, she found she hadn’t filled the washer with water.

Now let me tell you a funny thing: one day, father wanted to get up early as usual, buthe wasn’t able to do that, because he hadn’t set the alarm clock the night before, so when he got up, he did everything in a hurry. After father left, mother said to me mysteriously, "He will come back soon." "Why?" I was greatly surprised. "Because today is Sunday, his holiday!" Just as mother said, father came back home soon, and went to bed again--he was too tired.

Australia is one of the famous Oceanian country. The country is famous for its wool production and seashore tour. As the climate there is warm and comfortable, many people spend vocations there every year. I’m a super fan of water entertainment, so I choose it as my destination.

In Australia, the sky is bluer than blue, the clouds are whiter than white, all the local people enjoy an optimistic and active life. They also show their kindness and enthusiasm to the tourists.

The first step should be Sydney Opera which is among the most brilliant and splendid architectures in the world. Many world-class plays are put on in it .The surface and shape of it is like a seashell with glory decorations inside.

Then Melbourne is a good choice to be as the next step. In Melbourne, skin screen is a must to take with as the sunshine is upset and may burn your skin. The most attractive thing to me is the Australia Open, which is one of the biggest world-class tennis competition. Many great players such as Roddick Federer and its local player Hewitt etc. gather to compete. It’s really a feast for the eyes.

Australia is also home to one of the most challenging and exciting surfing and diving projects. As we know, it is always called “a country riding on the back of sheep”. From the interesting saying ,we can know something about the rich wool-production country. If you love animals, kangaroos and kaolas are good company to you .

So don’t forget Australia when you plan a trip.

Salaries should reflect people’s dedication and job responsibilities.

However, sports figures, who don’t benefit the community in general, earn

millions of dollars each. In my opinion this is wrong. Things should be done to

change this situation.

If we take the example of a sport star such as Tyson, it is hard for us to

say in what way he benefits the society. In fact, his disobeying game rules sets

a bad example for young people, and his abandoned behavior encourages people to

experiment with sex and violence. Besides, his job does not require special

skills or years of training and education. Although he can entertain and excite

audience, I do not think he is justified to receive so much money and his job

can be considered essential.

On the other hand, most people in ‘ordinary’ professions like nurses,

doctors and teachers earn only a small fraction of the income of these “stars”.

However, if we give a careful look at these professions, we will find that they

not only require special skills and years of education but also help the people

and the whole society. For instance, teachers disseminate knowledge to the

society; doctors and nurses give patients good medical care and prolong their

life. They are much more useful, and actually more essential to society than

sports personalities. Without these ‘ordinary’ professions, our society would

stop progressing. Their salaries should relate to skill, education or the value

of the inpidual to society.

Things should be done to make salaries fairer. Huge amounts of money shall

be given to more deserving people. It seems that the only solution is to impose

heavy taxes upon people who earn excessively high salaries.

Smoke after the fire, smoke, contains the chemical composition of tobacco in all, at the same time than the tobacco itself and added some harmful substances, such as carbon monoxide, tobacco tar and so on. This is because in addition to the tobacco itself, in the process of cigarette made, to add some cocoa in raw materials, liquorice, sugar, glycerin, such as ethylene glycol, moist, taste fragrance and combustion-supporting material.

烟里有一种对人身体不好的东西——尼古丁。

一枝香烟中的尼古丁可以毒死一只小白鼠,25g的香烟里的尼古丁可 毒死几头牛,40至60毫克纯尼古丁可以毒死一个人。

尼古丁的危害也是相当的大,它可以引起胃痛或其它胃病;还会使人引起心律不正诱发心脏病;严重的还可能引起癌症的爆发。

香烟是隐藏在我们身边的隐形杀手,是大家所应警惕的。

据科学家测定,烟草中含有数百种复杂的化学成分,大部分对人体有害,其中焦油、尼古丁、酚类、醇类、酸类、醛类等40种是有毒和有致癌作用的物质。烟在点燃后,所产生的烟雾,包含了烟草中所有的化学成分,同时比烟草本身又增加了一些有害物质,如一氧化碳和烟焦油等。这是因为除烟草本身外,在制成卷烟的过程中,要在原料中加入一些可可、甘草、糖、甘油、乙二醇等调味、湿润、产香、助燃物质。这些添加剂虽然本身无害,但在燃烧过程中却起了变化。例如,在鼠背涂上可可燃烧后产生的烟油,可长出皮肤瘤。甘草中的甘草酸在燃烧后,与其他成分化合,可生成有致癌作用的多环芳烃。糖与烟草一起燃烧后增加了焦油量,而糖燃烧后的产物是烟中的一个重要致癌物。甘油和乙二醇在燃烧后的物质,不但可能使吸烟者患膀胱癌,而且所产生的丙烯醛可抑制气管和纤毛分泌物从肺内排出,从而增加患气管炎和肺气肿的机会,并使患有这两种病的人病情加重。

烟对人的危害是多么大啊!所以我们不能吸烟。杜绝吸烟,造福后人。
