如何应对全球气候变暖的话题写英语作文
With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike. So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.With the development of economy, more and more greenhouse gases are being discharged into the air.

英语作文一篇，关于粮食短缺问题
Most Americans take food for granted. Even the poorest fifth of households in the United States spend only 16 percent of their budget on food. In many other countries, it is less of a given. Nigerian families spend 73 percent of their budgets to eat, Vietnamese 65 percent, Indonesians half. They are in trouble. Last year, the food import bill of developing countries rose by 25 percent as food prices rose to levels not seen in a generation. Corn doubled in price over the last two years. Wheat reached its highest price in 28 years. The increases are already sparking unrest from Haiti to Egypt. Many countries have imposed price controls on food or taxes on agricultural exports. Last week, the president of the World Bank, Robert Zoellick, warned that 33 nations are at risk of social unrest because of the rising prices of food. “For countries where food comprises from half to three-quarters of consumption, there is no margin for survival,” he said. Prices are unlikely to drop soon. The United Nations Food and Agriculture Organization says world cereal stocks this year will be the lowest since 1982. The United States and other developed countries need to step up to the plate. The rise in food prices is partly because of uncontrollable forces — including rising energy costs and the growth of the middle class in China and India. This has increased demand for animal protein, which requires large amounts of grain. But the rich world is exacerbating these effects by supporting the production of biofuels. The International Monetary Fund estimates that corn ethanol production in the United States accounted for at least half the rise in world corn demand in each of the past three years. This elevated corn prices. Feed prices rose. So did prices of other crops — mainly soybeans — as farmers switched their fields to corn, according to the Agriculture Department. Washington provides a subsidy of 51 cents a gallon to ethanol blenders and slaps a tariff of 54 cents a gallon on imports. In the European Union, most countries exempt biofuels from some gas taxes and slap an average tariff equal to more than 70 cents a gallon of imported ethanol. There are several reasons to put an end to these interventions. At best, corn ethanol delivers only a small reduction in greenhouse gases compared with gasoline. And it could make things far worse if it leads to more farming in forests and grasslands. Rising food prices provide an urgent argument to nix ethanol’s supports. Over the long term, agricultural productivity must increase in the developing world. Mr. Zoellick suggested rich countries could help finance a “green revolution” to increase farm productivity and raise crop yields in Africa. But the rise in food prices calls for developed nations to provide more immediate assistance. Last month, the World Food Program said rising grain costs blew a hole of more than $500 million in its budget for helping millions of victims of hunger around the world. Industrial nations are not generous, unfortunately. Overseas aid by rich countries fell 8.4 percent last year from 2006. Developed nations would have to increase their aid budgets by 35 percent over the next three years just to meet the commitments they made in 2005. They must not let this target slip. Continued growth of the middle class in China and India, the push for renewable fuels and anticipated damage to agricultural production caused by global warming mean that food prices are likely to stay high. Millions of people, mainly in developing countries, could need aid to avoid malnutrition. Rich countries’ energy policies helped create the problem. Now those countries should help solve it.

Causes and symptoms
Causes
No one knows what causes a person to be addicted to the Internet, but there are several factors that have been proposed as contributing to Internet addiction. One theory concerns the mood-altering potential of behaviors related to process addictions. Just as a person addicted to shopping may feel a "rush" or pleasurable change in mood from the series of actions related to a spending spree— checking ones credit cards, driving to the mall, going into ones favorite store, etc.— the person with an Internet addiction may feel a similar "rush" from booting up their computer and going to their favorite web sites. In other words, some researchers think that there are chemical changes that occur in the body when someone is engaging in an addictive behavior. Furthermore, from a biological standpoint, there may be a combination of genes that make a person more susceptible to addictive behaviors, just as researchers have located genes that affect a persons susceptibility to alcohol.
In addition to having features of a process addiction, Internet use might be reinforced by pleasurable thoughts and feelings that occur while the person is using the Internet. Although researchers in the field of addiction studies question the concept of an "addictive personality" as such, it is possible that someone who has one addiction may be prone to become addicted to other substances or activities, including Internet use. People with such other mental disorders or symptoms as depression, feelings of isolation, stress, or anxiety, may "self-medicate" by using the Internet in the same way that some people use alcohol or drugs of abuse to self-medicate the symptoms of their mental disorder.
From a social or interpersonal standpoint, there may be familial factors prompting use of the Internet. For
People who develop problems with their Internet use may start off using the Internet on a casual basis and then progress to using the technology in dysfunctional ways. Use of the Internet may interfere with the persons social life, school work, or job-related tasks at work. Many of the treatments that have been used for Internet addiction have been modeled after other addiction treatment programs and support groups. (Oleg Nikishin/Getty Images. Reproduced by permission.)example, a person might "surf the Web" to escape family conflict. Another possibility is that social or peer dynamics might prompt excessive Internet use. Some affected persons may lack the social skills that would enable them to meet people in person rather than online. Peer behavior might also encourage Internet use if ones friends are using it. Modeling may play a role—users can witness and experience how others engage in Internet use and then replicate that behavior. The interactive aspects of the Internet, such as chat rooms, e-mail, and interactive games like Multi-User Dungeons and Dragons (MUDS), seem to be more likely to lead to Internet addiction than purely solitary web surfing.
One question that has not yet been answered concerning Internet addiction is whether it is a distinctive type of addiction or simply an instance of a new technology being used to support other addictions. For example, there are gambling casinos on the Internet that could reinforce a persons pre-existing gambling addiction. Similarly, someone addicted to shopping could transfer their addiction from the local mall to online stores. Persons addicted to certain forms of sexual behavior can visit pornography sites on the Internet or use chat rooms as a way to meet others who might be willing to participate in those forms of behavior. Researchers may need to determine whether there is such a disorder as "pure" Internet addiction.
Symptoms
One symptom of Internet addiction is excessive time devoted to Internet use. A person might have difficulty cutting down on his or her online time even when they are threatened with poor grades or loss of a job. There have been cases reported of college students failing courses because they would not take time off from Internet use to attend classes. Other symptoms of addiction may include lack of sleep, fatigue, declining grades or poor job performance, apathy, and racing thoughts. There may also be a decreased investment in social relationships and activities. A person may lie about how much time was spent online or deny that they have a problem. They may be irritable when offline, or angry toward anyone who questions their time on the Internet.
Demographics
In the past, people reported to have an Internet addiction disorder were stereotyped as young, introverted, socially awkward, computer-oriented males. While this stereotype may have been true in the past, the availability of computers and the increased ease of access to the Internet are quickly challenging this notion. As a result, problematic Internet use can be found in any age group, social class, racial or ethnic group, level of education and income, and gender.
Diagnosis
As previously noted, Internet addiction disorder has not yet been added as an official diagnosis to the DSM. The following, however, is a set of criteria for Internet addiction that has been proposed by addiction researchers. The criteria are based on the diagnostic standards for pathological gambling.
The patient must meet all of the following criteria:
He or she is preoccupied with the Internet (thinks about previous online activity or is anticipating the next online session).
He or she needs to spend longer and longer periods of time online in order to feel satisfied.
He or she has made unsuccessful efforts to control, cut back, or stop Internet use.
He or she is restless, moody, depressed, or irritable when attempting to cut down or stop Internet use.
He or she repeatedly stays online longer than he or she originally intended.
The person must meet at least one of the following criteria:
He or she has jeopardized or risked the loss of a significant relationship, job, educational or career opportunity because of Internet use.
He or she has lied to family members, a therapist, or others to conceal the extent of involvement with the Internet.
He or she uses the Internet as a way of escaping from problems or of relieving an unpleasant mood (such as feelings of helplessness, guilt, anxiety, or depression).
Treatments
Since Internet addiction disorder is a relatively new phenomenon, there is little research on the effectiveness of treatment procedures. Some professionals advocate abstinence from the Internet. Others argue that it may be unrealistic to have a person completely end all Internet use. As society becomes more and more dependent on computers for business transactions, educational programs, entertainment, and access to information as well as interpersonal communication, it will be difficult for a computer-literate person to avoid using the Internet. Learning how to use the Internet in moderation is often the main objective in therapy, in a way analogous to the way that people with eating disorders need to come to terms with food. Many of the procedures that have been used to treat Internet addiction have been modeled after other addiction treatment programs and support groups.
If a persons Internet addiction disorder has a biological dimension, then such medication as an antidepressant or anti-anxiety drug may help them with these aspects of the addiction. Psychological interventions may include such approaches as changing the environment to alter associations that have been made with Internet use, or decrease the reinforcement received from excessive Internet use. Psychological interventions may also help the person identify thoughts and feelings that trigger their use of the Internet. Interpersonal interventions may include such approaches as social skills training or coaching in communication skills. Family and couple therapy may be indicated if the user is turning to the Internet to escape from problems in these areas of life.
Relapsing into an addictive behavior is common for anyone dealing with addiction disorders. Recognizing and preparing for relapse is often a part of the treatment process. Identifying situations that would trigger excessive Internet use and generating ways to deal with these situations can greatly reduce the possibility of total relapse.
Prognosis
Although extensive studies have not yet been done, treatment appears to be effective in maintaining and changing the behavior of people drawn to excessive use of the Internet. If the disorder is left untreated, the person may experience an increased amount of conflict in his or her relationships. Excessive Internet use may jeopardize a persons employment or academic standing. In addition, such physical problems may develop as fatigue, carpal tunnel syndrome, back pain, and eyestrain.
Prevention
If a person knows that he or she has difficulty with other forms of addictive behavior, they should be cautious in exploring the types of application that are used on the Internet. In addition, it is important for people to engage in social activities outside the Internet. Finally, mental health workers should investigate ways in which to participate in the implementation of new technology rather than waiting for its aftereffects.

关于节约粮食的英语作文
How many times I have seen a company or organisation habitually waste good food?! Too many times! They are well-meaning people, and theyd like to give away the food instead of wasting it by putting it in the dustbin. Theyd maybe like to give the food to the needy or the poor, and theres probably a few beggars just along the road if anyone was kind enough to go along and see if they are hungry. So why dont they do it? Reason: Too many stupid rules! Just as surely as theres no pig bin anymore for food to be recycled as pork (because of various illconceived ideas about the health of pigs if they eat other peoples sunday lunches and leftovers), theres no "well lets give it to the beggars!". Apparently, beggars can in theory take the company to court if they are made ill by the food. Not that they are seriously going to be made ill by perfectly good food, and not that most beggars have the money to start a legal case.

帮我写篇粮食危机的英语作文，100词左右
Hello, everyone, Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation. Then what should we do to deal with the problem? On one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage. As for me, I will call on the people around me to live thriftily. And for the moment, I think, we should study hard to develop science and help solve the food shortage in the future.
