Love is everything. Love is the most brilliant thing in the world. Because

of love, our world turns out to be a sunny place.

We couldnt go without love. For instance, love can help us communicate

with each other very well, love can help us overcome all the difficulties, love

can help us get rid of our unhappiness, love can turn our enemies into our

friends, and our destinies can also be changed by love.

Whats more, love is a bowl of rice for a hungry beggar, love is an

overcoat for a tramp in winter days, love is an umbrella for us in raining days,

love is a stick for the old, love is the best medicine for the sick, love is the

sunlight for the blind, and love is the gospel for the deaf. Without love, our

world is meaningless.

However, love isnt a bunch of flowers or a nice present. Love is a thread

in our coat. Love is inside, making our life warm and comfortable.

Marcel Hirscher continued his dominant start to the alpine skiing World Cup season with yet more milestones on Sunday.

The Austrian, seeking an unprecedented fifth consecutive overall title, became the first man to win three successive giant slalom races at the Alta Badia venue, in Italys Dolomite mountains.

He claimed the World Cup lead from Aksel Lund Svindal, moving 20 points ahead of the Norwegian -- who was 28th, following his two speed-event wins in preceding days at nearby Val Gardena.

Hirscher claimed his fourth victory this season, and his third in giant slalom -- a technical discipline where he already leads by 134 points after only four rounds.

He was 0.19 seconds ahead of Norways Henrik Kristoffersen after the two runs, while Frances Victor Muffat-Jeandet was third.

"I skied at my 100% limit in the second run," Hirscher said after the 35th win of his career put him one behind sixth-placed compatriot Benjamin Raich in the all-time standings.

"It was difficult snow, not as icy as were used to here in Alta Badia and I think that Henrik skied a smoother run, but I gave it all my power and in the end I am really happy to come away with the win."

In Sundays womens action, Eva-Maria Brem made it a double giant slalom success for Austria by winning in Courchevel, France.

Switzerlands Lara Gut, who won twice at Val dIsere in Fridays alpine combined and Saturdays downhill, tied for second with Norways Nina Loeseth.

Gut extended her overall World Cup lead to 58 points over American star Lindsey Vonn, who was 13th following her crash on Saturday.

"I didnt really feel very balanced today," Vonn said. "I think I just rung my bell a little bit yesterday."

Brem claimed her second career World Cup victory, having been runner-up in the previous giant slalom races at Aspen and ?re.

"Every season I just need that one moment when everything gets together -- that one run, like the second one in Aspen when I felt, This is how I need to keep this working," the 27-year-old said.

"I knew what I had to do, but waiting at the start was tough. That second victory was beautiful too and that made me cry."

the author creates, I treat myself as part of the novels, it feels like that I

witness all the incidents. I especially like to read short novels, because I

don’t have so much to read the long novels, I am studying in the high school, I

have many subjects to learn. I have little time only on the weekends. Short

novels only costs me about one day to finish reading, while the long novels will

take me more than a week to finish, if I hang on reading part of it, I will

think about it all the time and can’t focus my mind on studying. What’s more, I

like to read novels more than twice, so it is easy to do for me to read short

In my life I have met many people who are really worth mentioning.But perhaps the most unforgettable person I have ever known is my English Teacher.

It is his special quality that is always kept in my memory.

For one thing,I was attracked by his wide range of knowledge.I remember that we students always attended his class with great eaherness because his lectures were humourously delivered,and he never failed to give us valuable advice.Nothing seemed difficult to learn after his explanation.

For another,I was deeply impressed by the respect he showed for us.As he treated us like friends rather than students,we all liked to visit his home for social activities as well as for advice.

Although it is over a year now since I attended his last class,he is the talk of our old classmates,and I know part of him has already stayed in my heart.

篇7:我的英语老师初中

一直都想写我的英语老师,只是因为觉得学习不好,颇感内疚,不好意思来写。用我妈妈的话来说,他就是一个小男孩,我应该叫哥哥的。

他说话的样子十分夸张。他跟我们说在另一所学校里做班主任时,他安排的座位非常合理,因此学生成绩提高很快。我当然理解他的自豪,但我也理解我的班主任为何不采用。因为丁老师谈建议时的神情就像一只狗伸着舌头,流着口水,教一只猫如何分配自己盘中的鱼。明明一张很英俊的脸,有棱有角,鼻梁挺直,眼睛凹下,嘴唇也很性感。你不知道呀!他生气时目光看向远方,深沉而坚定,加上魁梧的身材,就像一位年轻的法老,站在他的城墙上,指点江山。可是除了生气时像个男人外,其他时候就是个小男孩了,大笑起来嘴很夸张地向上翅起,就像卡通画,让所有的人都可以感受到他的快乐。若是说到什么好事,他就像大公鸡似的炫耀他的两根粗粗的眉毛向上飞扬,眼中不时闪着像星星一样的光点,还手舞足蹈的,唾沫横飞,经常唾到前排同学的脸上。被人夸奖的时候,又显得女里女气的,十分腼腆。每次开考前,他在教室门外,他的嘴角像一只红色的狐狸,在雪中伸着一只爪子,望着一只兔子。

英语老师姓丁,家在阳曲,可能地理位置有些偏辟,所以考出来不大容易。本来在另一所中学里教高中,后来考入我校,校长让他教初中。这让他十分失望,有时还在学生中露出了像李白一样怀才不遇的痛苦和颓唐。有时又高兴地告诉我们,我们是他教的第一拔学生!?

可能是刚刚带学生,他有年轻老师的激情,为我们自费复印英语资料,很喜欢在读英语课文时,一边作着奇里古怪的样子,一边发出奇里古怪的声音。有时上课,讲着讲着就讲起了自己的自传,于是常常在自我的唾沫星子中陶醉得难以自拔。上他的课让我感到十分的快乐和高兴,只是因为成绩不好而十分愧对他。不知为什么,我学也学不好,只能在每次考完试以后都躲着他。很亏心很愧疚地面对他对我的微笑,但他从来不说我不好,一次又一次地原谅我。

又一次,语文老师让我们以描写一位老师的神态特征为作业,到了下节课是英语。他进来十分讨好的让我们写他。回家后我写了两篇,有一篇是写他的,到了教室,临交作业时我又拿回了,结果我的另一篇得了第一,上课时他说已看过,可惜不是写他的。到后来越到中考我觉得愧对老师,现在考完了,我却一直想着他,想着欠他的一篇作文。

Transportation has been greatly changed in the past few years. In ancient

days, people used to travel by horse or carriage. The journey was often tiring

and tedious. Then people had buses, trains and ships, which could shorten the

time of the long-distance trip. Now we have not only more private cars, but also

planes and high-speed rails. All of these modern transports could offer us a

if you want to understand adversity, take two identical acorns from the same oak tree and plant them in two different locations. plant the first in the middle of a dense forest, and the other on a hill by itself.

要是你想理解什么是逆境,就去拿两颗从同一棵树上摘下来年龄相同的橡树果,并且把它们种到不同的地方。第一颗种在浓密的树林当中,而另外一颗则单独种在一座山上。

heres what will happen. the oak standing on a hillside is exposed to every storm and gale. as a result its roots plunge deep into the earth and spread in every direction, even wrapping themselves around giant boulders. at times it may seem the tree isnt growing fast enough—but the growth is happening underground. its as if the roots know they must ported the tree from the threatening elements.

事情的结果便是这样。那颗长在山上的橡树经历了大风大雨,结果它的根深深地扎进了泥土中间,并不断向四周扩张,甚至把自己置身于巨大的石块当中。有时它可能看起来长的不是很快,但这时它却在地下悄悄生长着,好像它的根知道自己必须快速生长来保护树木免受自然危害的影响。

篇17:怀念的英语作文初中

全文共 2558 字

When memory began for me, my grandfather was past sixty-a great tall man

with thick hair becoming gray. He had black eyes and a straight nose which ended

in a slightly flattened tip. Once he explained seriously to me that he got that

flattened tip as a small child when he fell down and stepped on his nose.

The little marks of laughter at the corners of his eyes were the prodnct of

a kindly and humorous nature. The years of work which had bent his shoulders had

never dulled his humour nor his love of a joke.

Everywhere he went, "Gramp" made friends easily. At the end of half an hour

you felt you had known him all your life. I soon learned that he hated to give

orders , but that when he had to, he tried to make his orders sound like

suggestions.

One July morning, as he was leaving to go to the cornfield, he said :

"Edwin, you can pick up the potatoes in the field today if you want to do that.

" Then he drove away with his horses.

The day passed, and I did not have any desire to pick up potatoes. Evening

came and the potatoes were still in the field. Gramp, dusty and tired, led the

horses to get their drink.

"How many bags of potatoes were there?" Gramp inquired. "I dont know.

"

"How many potatoes did you pick up?"

"I didnt pick any. " "Not any! Why not?"

"You said I could pick, them up if I wanted to. You didnt say I had to.

"

In the next few minutes I learned a lesson I would not forget: when Gramp

said I could if I wanted to, he meant that I should want to.

Gram hated cruelty and injustice. The injustices of history, even those of

a thousand years before, angered her as much as the injustices of her own

day.

She also had a deep love of beauty. When she was almost seventy-five, and

had gone to live with one of her daughters, she spent a delightful morning

washing dishes because, as she said, the beautiful patterns on the dishes gave

her pleasure. The bird, the flowers, the clouds-all that was beautiful around

her- pleased her. She was like the father of the French painter, Millet, who

used to gather grass and show it to his son , saying , "See how beautif ul this

is ! "

In a pioneer society it is the harder qualities of mind and character that

are of value. The softer virtues are considered unnecessary. Men and women

struggling daily to earn a living are unable, even for a moment, to forget the

business of preserving their lives. Only unusual people, like my grandparents,

manage to keep the softer qualities in a world of daily struggle.

Such were the two people with whom I spent the months from June to

September in the wonderful days of summer and youth.

Today, the world is globalized and more and more foreigners come to China

With the development of Internet, the world gets smaller, because the

communication between countries has increased. America is the superpower all the

Chinese people and American people. It is known to all that China’s market is

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.
