The major reason of global warming is due to human activities, the green house gases such as carbon dioxide and nitrogen oxides produced by the industry traps the energy from the sun. If there is no such gas in the atmosphere, the earth will be too cold for any living organism to survive, it is natural to have some green house gases in the air and some people argue that even without human effect there are evidences show that the temperature of the earth increase and decrease in cycles, and now we are reaching another ice age. One of the concerns is that the green house gases increased so fast that it is now a big threat to all the species on the earth. The human activities that cause global warming are deforestation which means that less carbon dioxide can be converted back into oxygen, use of fossil fuels which releases the carbons that accumulated for many years and the consequences are the rising of sea level, melting of ice in the Antarctic and increase in temperature. Rising in sea level means that the space for the land organism decreases. Melting of ice mean the release of any harmful substances that may have been trapped thousand of years ago and also cause a further rise in sea level. The increase in temperature will also provide a better condition for bacteria and virus to grow which means more diseases.
People around the world may feel that the climate has been getting steadily warmer andwarmer in recent years. Places which used to be abundant in snowfall have frequentlyexperienced snowfreewinters.
Drought lasts longer in some dry areas.People findthat without air conditioners they could hardly work or fall asleep on hotter summer daysg.
The side effects of global warming are alarminS. A warmer global climate melts the icecaps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severestorms, hurricanes(想风).People suffer a lot from disasters relevant to global warming.
To stop global warming we should make immediate and continual efforts. We hope thesituation will soon change.Global warming catches and holds our concern, for it affects usand will affect our later generations. We cannot wait any longer. Do it right now.
Directions: For this part, you are allowed 30 minutes to write a short essay on the topic Environmental Protection. You should write at least 120 words following the outline given below.
No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.
There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.
It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .
How time flies! Four moths have passed since we saw each other last time. I cannot help but miss you. You asked me about Chinese Spring Festival. Now I would like to tell you something about it。
The Spring Festival is a Chinese traditional festival. It is the most important and enjoyable one. A few days before the festival, houses are cleaned and red couplets are put up on the doors of every household. They are said to frighten away the ghosts. On that day, people are dressed up. Firecrackers ring out in the air, which adds to the atmosphere of the festival. People after a years hard work begin to relax and visit one another. Presents and dinners are given to celebrate the happy reunion of friends and relatives. Families get together. They have jiaozi and enjoy the New Year TV show. Customs may vary from place to place, but the same happy atmosphere is to be found everywhere in the country。
Now, I hope you have some idea of Chinese Spring Festival。

外卖风靡校园The Popularity of Take-out Food in School
Nowadays, as the more choices for students in the school, some students can’t bear the school’s canteen, they call the take-out food. The producers sense the business opportunity, they advertise their food, attracting more students to order their food, and then they promise to provide the perfect service, which means they can bring the food to the students’ room. The problem is that school bans the take-away food, on the one hand, the school needs students to consume in the canteen, on the other hand, they want to make sure the students’ healthy. Most students choose to order the take-out away food in secret, though it may danger their health. In my opinion, the school should change their menu for some time, they need to cook the food that is suit to the students’ taste, they could learn what kind of food the students like, and then adjust the menu. The take-away food will be reduced naturally.

Should the Golden Week Holidays BeAbolished?
There is no denying the fact that the introductionof the Golden Week holidays in China has considerably promoted the development of thenation’s economy and touring industry and enriched people’s life. People around the countryhave spent more time and money traveling and relaxing themselves.
As every coin has two sides, the Golden Week holidays have also brought about piles ofproblems. For one thing, due to the fact that people across the country are spending theirvacations during the same period of time, it is terribly crowded almost everywhere: trains,buses, hotels, scenic spots, etc., which have ruined people’s mood for vacations. For another,some businessmen take advantage of the weeklong holidays and raise the price ofcommodities and services.
Personally, I believe that it is necessary for people to have long vacations, but there is noneed for them to have the vacations during the same period of time. Instead, they should beallowed the freedom to arrange their own vacations. Only in this way can they really relax andrefresh themselves for a new round of work.
If you think about a younger sister, you don't want a crazy girl like her erratic. This summer vacation, she is a stick up will never let go, take me to the dead.
She is a born master plan, despite her age small, mind racing than sidon animals "little horse" of the novel. Not read how many books she had 36 plan of incisively and vividly. One day, the mother went into the kitchen to eat we eat fruit, she ran like mad to the kitchen and rolled up a plate like aside all kinds of fruit. Have long known that she is super fruit king, I know that should not take with her, then staged "lady" mode, let her take first. Unexpectedly, when I walked past "elegant", after the plate only lone a banana. "Alas," I with a heavy sigh, she is too hard. I was about to poke a banana, she suddenly reached out to rob. Fortunately, this young lady responds quickly, immediately lift the banana. "Hey, you also too bad." I said resentfully. After she heard, coquetry miraculously, said: "good sister, I haven't eat enough, you give me is the banana?" "No! I haven't eat!" I said angrily. Began to see not soft, hard, a madam, stretch hand to grab. I already familiar with her "moves", the electives. Her hand to the right, I will take the banana swing to the left; Her hand towards the left, I will give the banana to jilt to the right. See yourself with force afraid not line, only her eyes at a guru and smile at me. Mother often says her eyes can speak, at this time, her eyes as if to say: "ha ha, you of the end of the day, banana objects belong to the" owner "soon, wow kaka kaka!" At this time, I can't help but think of the horror film face ferocious witch, played a quivering, vigilance arises spontaneously. She held up his hand to rob my banana in the hand, I subconsciously pick bananas reach even higher. Said slowly, when the moment, she suddenly stretched out her clutches to scratch my body the most weak place - the belly. I immediately laughed, inadvertently a soft hand, banana fell. She immediately like a hunter hit prey, hold up my poor a banana is running. Good one by then enter the meter!
At the same time, she is a great master of gossip. I'm doing my summer homework, she like a rabbit ran "beeping", his eyes bright. "What?" I stepped back warily. She smiled and said: "elder sister, I tell you oh, I found the secret of the father." "What is the secret? Let's hear it." I immediately to the interest. She sells imprison son and stopped for a while, slowly and said, "sister, I'm going to not tell you!" She said and ran away. Soon after, I finished my homework, see her in my diary. Don't! I immediately rush toward the past, a taken away. She said a wry smile: "elder sister, I know your secret." My face became livid, said: "you cannot say it out." She smiled and said: "no problem, however, elder sister, you want to help me wash the dishes." To help her wash the dishes! I don't! But I can't think of anything else, just nodded and agreed. I later learned that she was magically know the mother's secret. Know so many secret, useful? It was not until that day, I know there is no use. It was the summer vacation, I and my sister secretly watching TV at home, I didn't think be back early father saw, he said sternly: "I don't tell your mother!" She immediately stood up and rightfully said: "how dare you!" Oh my god! The momentum reminds me of my roars from the mountains of that kind of dignity, the kind of fierce waters against the rock, the sort of bold plunges three thousand feet. I say this is no exaggeration, father is a king, as a child she dare to outspoken to intimidate dad, affirmation is enough! She picked up a book casually, said: "be careful I told my mother you hide private..." She hasn't finished, dad's face immediately changed color, interrupted and said, "okay, I do not say, you can't say, let me catch you again next time in watching TV, you carefully to see how I tidy up you!" Watching me shocked with all this, thought: well, looks like a king and escapes the control of her gossip master!
She ah, counsel is not only a master, master of gossip, or a super annoying trick master. That day in the middle of the night, I got up and go to the toilet, came back, found that she actually gone! It scared me out in a cold sweat, just still in bed like a pig in a deep sleep now, how to push and push don't wake up, how to evaporate from your room now? Jitters in the room, I turned around, there's no one there. I thought, she can't be captured by monsters! I just get ready to go across the room to inform mom and dad, suddenly saw a white thing standing in the doorway, as it was night, the white was particularly clear. I saw the white terror things took up the "hand" of white came to me. My first reaction was: ah! Sister is seized the ghost returned to catch me! The second response is: "ah," screamed and ran back sharply. Ghost after seeing my reaction to burst out laughing. "What!" I watched "ghost" of angry white cloth cover on it, it was just evaporate from the room's sister. I said sternly, "where have you run!" She smiled and said in a sarcastic tone: "you're a fool, I have been hiding behind the door!" I learned the truth provocation.
Well, you said, there is such a younger sister, can not let a person afflictive? Oh, she is back! I am not to be taunted still can't afford to hide? Slipped quickly! What did you say? Hiss, small voice point, don't let her hear.
We believe with the promotion of medical ethics, the relationship between doctors and patients will become more harmonious.
Before every blind jump, we should keep in mind that it has to take a certain period of time before understands himself and then achieves great success.
Women will contribute to the society as much as men do, as we should give the same stage to perform.
In a word, only when the young and the elderly make joint efforts can the elderly parents spend their remaining years in happiness.
What I believe is that we should be aware of the necessity to step out of the doors and build a friendly relationship with others. In return , a warmer and more harmonious society could become possible.
In a word, each individual should pay more attention to others as well as the world outside.
All in all, I hope that government would adjust the schedule and let people enjoy a true week-long vacation.
The Prevalence of Western Holidays-it is noticeable that western holidays are becoming increasingly popular day by day, while Chinese traditional holidays are being somewhat neglected. Young people in China who are ignorant about Chinese traditional holidays are crazy about Christmas or Valentine's Day.
There are several possible reasons for this phenomenon. First, western nations, such as the United States and Britain, are powerful and dominant in every aspect.
Everything in these countries is assumed to be superior and adored by some modern young people. Second, the prevalence of English as a world language and the development of globalization enable western cultu
re to prevail in China. Last but not least, some Chinese people have blind faith in foreign things while treating our own possessions with contempt.
I am critical of this trend. China boasts a brilliant history and splendid traditions. Chinese tradition should be preserved and promoted. If this trend is allowed to continue, the priceless heritage of our ancestors will be replaced by western traditions. Nobody expects such a consequence. So let us join hand in hand to protect Chinese tradition, especially traditional holidays. (180 words)

2.Atmospheric pollution factors Currently,the increasingly serious environmental pollution has posed a major global problem,but also lead to global warming one of the main factors.Now,with regard to the study of global climate change has been clearly pointed out that since the late 1990s from the Earth's surface temperature has started to rise.
3.Marine ecological deterioration factors Currently,sea level change is a constant upward trend,according to experts predicted that the middle of the next century,the sea level could rise 50 cm.And if they do not take measures will lead directly to the destruction of freshwater resources and pollution adverse consequences.In addition,the land-based activities have a large number of establishments toxic chemical wastes and solid wastes discharged into the ocean,and so constantly; occurred in a major Chinese seawater (leakage) as well as oil and other incidents caused by human activities in coastal areas,environmental degradation and so on that led to the destruction of water ecological environment a major factor.
4.Land by erosion,desertification,and other factors destruction
5.Factors sharp decline of forest resources in the world,due to natural or man-made factors causing forest area is substantially sharp decline.
6.Factors acid rain acid rain harm to the ecological environment has been the impact brought about by more and more world attention.Acid rain can damage forests,acid lakes,threaten biological.At present,the world of acid rain and more concentrated in Europe and North America,acid rain occurred in most developed countries,some developing countries,acid rain is also growing rapidly and development.
7.Accelerate the extinction of species on Earth biological factors is a valuable human resources,and biodiversity is mankind's survival and development.But now the biological species on Earth are being lost at unprecedented rates.
8.Water pollution factors According to the Global Environment Monitoring System show that the water quality monitoring project,the world about 10% of the water pollution monitoring,in this century,human beings are the sharp increase in water consumption,water pollution and the scale is constantly expanding,fresh water on the formation and the need for the one pair of contradictions.Clearly,the treatment of water pollution is very urgent and important.
9.Toxic waste pollution factors growing toxic chemicals not only for the survival of mankind pose a serious threat,but also for the ecological environment of the Earth's surface will also bring harm.
