Cold sores are caused by the herpes simplex virus . They are very contagious. Usually, you will have tenderness, tingling, or burning before the actual sore appears. Cold sores usually begin as blisters and then crust over. The herpes virus can live in your body for years. It only appears as a mouth sore when something triggers it, such as:
Another illness, especially if there is a fever
Hormone changes (such as menstruation)
Stress
Sun exposure
Canker sores are not contagious. They may look like a pale or yellow ulcer with a red outer ring. You may have one, or a group of them. Women seem to get them more than men. The cause of canker sores is not clear. It may be due to:
A weakness in your immune system (for example, from the cold or flu)
Hormone changes
Stress
Lack of certain vitamins and minerals in the diet, including vitamin B12 or folate
Less commonly, mouth sores can be a sign of an illness, tumor, or reaction to a medication. This can include:
Autoimmune disorders (including systemic lupus erythematosus)
Bleeding disorders
Cancer of the mouth
Infections such as hand-foot-mouth disease
Weakened immune system -- for example, if you have AIDS or are taking medication after a transplant

The full IELTS Essay:

The last two decades have seen enormous changes in the way people's lives are affected by IT, with many advances in this field. However, while these technological advances have brought many benefits to the world, it can be argued that these developments in IT will result in more negative impacts than postive.

To begin, email has made communication, especially abroad, much simpler and faster, resulting in numerous benefits for commerce and business. Furthermore, the World Wide Web means that information on every conceivable subject is now available to us. For example, people can access news, medical advice, online education courses and much more via the internet. It is evident that these improvements have made life far easier and more convenient for large numbers of people and will continue to do so for decades to come.

Nevertheless, the effects of this new technology have not all been beneficial. For example, many people feel that the widespread use of email is destroying traditional forms of communication such as letter writing, telephone and face-to-face conversation. This could result in a decline in people's basic ability to socialize and interact with each other on a day-to-day basis.

In addition, the large size of the Web has meant that it is nearly impossible to regulate and control. This has led to many concerns regarding children accessing unsuitable websites and viruses. Unfortunately, this kind of problem might even get worse in the future at least until more regulated systems are set up.

In conclusion, developments in IT have brought many benefits, yet I believe developments relating to new technology are likely to produce many negative effects in the future that must be addressed if we are to avoid damaging impacts to individuals and society.

3) Conclusion

The conclusion only needs to be one or two sentences, and you can do the following:

Re-state what the essay is about (re-write the last sentence of your introduction in different words)
Give some thoughts about the future
Here is an example:

2) Body Paragraphs

For an IELTS essay, you should have 2 or 3 body paragraphs - no more, and no less.

For your body paragraph, each paragraph should contain one controlling idea, and have sentences to support this.

Lets look at the first paragraph for the essay about IT. The essay is about the benefits and drawbacks of IT, so these will need to be discussed in separate paragraphs.
Here is the first body paragraph:

To begin, email has made communication, especially abroad, much simpler and faster, resulting in numerous benefits for commerce and business. Furthermore, the World Wide Web means that information on every conceivable subject is now available to us. For example, people can access news, medical advice, online education courses and much more via the internet. It is evident that these improvements have made life far easier and more convenient for large numbers of people and will continue to do so for decades to come.

The controlling idea in this first paragraph is the 'benefits of IT', and there are two supporting ideas, which are underlined. No drawbacks are discussed as the paragraph would then lose coherence.

Most of the essay will focus on the negative aspects of IT, as the writer says there are more negative effects in the introduction. So the next two paragraphs are about these.

The topic sentence in the next paragraph therefore tells us we are changing the focus to the negative points:

Nevertheless, the effects of this new technology have not all been beneficial. For example, many people feel that the widespread use of email is destroying traditional forms of communication such as letter writing, telephone and face-to-face conversation. This could result in a decline in people's basic ability to socialize and interact with each other on a day-to-day basis.

The final body paragraph gives the last negative effect:

In addition, the large size of the Web has meant that it is nearly impossible to regulate and control. This has led to many concerns regarding children accessing unsuitable websites and viruses. Unfortunately, this kind of problem might even get worse in the future at least until more regulated systems are set up.

) Introduction

You should keep your introduction for the IELTS essay short. Remember you only have 40 minutes to write the essay, and some of this time needs to be spent planning. Therefore, you need to be able to write your introduction fairly quickly so you can start writing your body paragraphs.

You should do just two things:

State the topic of the essay, using some basic facts (that you may be able to take from the question)
Say what you are going to write about
Here is an example introduction for the above essay question about IT:

The last two decades have seen enormous changes in the way people's lives are affected by IT, with many advances in this field. However, while these technological advances have brought many benefits to the world, it can be argued that these developments in IT will result in more negative impacts than postive.

As you can see, the first sentence makes sure it refers to the topic (IT) and uses facts about IT taken from the question. Note that these are paraphrased - you must not copy from the rubric!

The second part then clearly sets out the what the essay will be about and confirms the writers opinion (some questions may not ask for your opinion, but this one does).

28/01/2015

An IELTS essay is structured like any other essay; you just need to make it shorter. There are three key elements:

Introduction
Body Paragraphs
Conclusion
We will look at each of these in turn, using the essay question above as an example.
