Most of the computer attack could be occurred via the internet activities and CD-Rom. First of all, Virus is one of the well-known dangers which hides in documents and is not too risky. It can only become dangerous when computer might be crashed by the virus. For instance, Trojan horse is one of the typical viruses which get the personal information and abuse it to take advantages like steal money from people’s bank account to buy something. Unfortunately, it is costly to solve this problem since a lot of efforts need to be put on the discovery and deletion of the virus. Another source of the danger is called spyware which is slightly similar to Trojan House, that is to say, it will also hide inside the computer without notification. However it seems to be less threatening since it only collects the information from the computer for commercial purposes. On the other hand, Spam, i.e. an unwanted advertisement or junk email, is the least dangerous of computer danger, and generally 50% of the email can be considered as junk email. Sometimes,through the spam, it is intended to thick you to get some information, this kind of attack is called “Phishing”. If you have already applied the spam by giving all of your information such as bank password, and as a result, you are going to lose your money. To avoid computer to be under attack, we not only have to keep our antivirus program up-to-date, but also need to be alert on the email that asked you to provide your personal details to them.

Sometimes the attacks are harmless and funny but mostly it is very serious.

Next, “Trojan Horse” is a type of virus that collects your credit card and banking details so that they can steal your money. In addition, there is also spyware. It functions like “Trojan Horse” but it does not cause any damages to your computer. They collect information such as your online purchases and then send it to commercial companies. Another popular attack is spam or unwanted advertising. It is less dangerous than virus and is consider as junk mail. Nowadays, more than 50% of all mails are junk mails.

computer is a essential device in our life ------------Abdallah
Firstly, computer save our time indeed .Many things could be accomplished during to a short time with even no potential .Admittedly, it have changed our daily life . For example ,ten years ago people were using post mail as a connection between them. Nowadays, it became more easier to send a message by email .
Secondly, it's a "multifunction" could be one of the reason why computer is a necessary part in the life . Internet, Microsoft office , calculator and Recorder are some of the useful function in computer .For instance ,Internet has converted the world to a small village. Moreover, people contact with others by chatting programs. In addition, companies, can performance a high quality documentaries by overwhelming number of graphics programs .

Using computers saves a lot of time - Sifa
Firstly, with internet we can receive and reply letter within one to two hours compared to mail. People can get feed back quickly through them. We also can make online banking to pay our household bills without go to the bank. This can save plenty of times. Moreover, a lot of information we can get easily from internet. For instance, people can access updated news around the world as well as the latest products selling in the market.
On the other hand, there are several drawbacks using computer. First of all, students will copy their assignments directly from internet. This habit becomes serious among students especially at the university. They can be terminated due to plagiarism. Furthermore, students also tend to make a lot of spelling mistakes in exams. This is because, computer can correct spelling automatically. Some of people also become addict to internet. Application such as facebook, twitter and games would make them immobile.
On the whole, plenty of work can be done using computer. It is also a device that make us very convenient. However, we must know the limit and control ourself when using computer. Otherwise, a problem will be occured if we misused it.
Hello guys, well, seem this course is about writing, so i'm doing more writing to improve it. Any comments from you all especially Emma are most welcome. Bye, have a great weekend...
Cars should be banned from city centres - Sifa
First of all, more cars in town resulted in traffic jam. Everybody is using their own vehicle to office or take their children to school. The problem becomes worse especially during peak hour. Secondly, plenty of cars in major road can cause accident. The risk of accident occurs is higher due to the difficulties driving in congested area. In addition, we also can reduce the level of air pollution if automobiles are prohibit to major cities. This is because, emission from exhaust contains carbon monoxide and it will contribute to the green house gases.
However, some people think that this is not a best solution to solve the problem. Motor vehicles are not allow to town mean that we must use public transport to commute from one place to another. A lot of time will be wasted, while waiting bus and train because the system is not effisyen. Furthermore, using public transport in rush hour is not comfortable for those who do not like crowd. It is also can lead to crime, such as pick-pocket, snatch thief and so on.
Inevitably, automobiles are essential to everyone. Prohibit cars from major city is not a good way to overcome this issue. Therefore, government should take their role to solve this problem.

There are some disadvantages of owning children mobile phones. Firstly, it causes an antisocial kid who can't communicate with others directly .Secondly,the child could be distracted from his studies because it's a multi function device such as games .In addition ,children are irresponsible to be own a cell phone.

Children below the age of 12 should not be allowed to own mobile phones. - Lily
Many parents have different view on the age of their children receiving a mobile phone. There are parents who insist that children under the age of 12 should not be allowed to have mobile phones while there are those who disagree.
Firstly, children under 12 years old should not receive a mobile phone is because they will shy away from meeting new people and become antisocial. Secondly, it will distract them from their studies as mobile phone contains lots of applications namely games that will consume most of their time. Furthermore, there will be wastage of money since children that young will not know the value of money and won’t control their spending. Lastly, there is also the fear of children growing up to be materialistic and demand for newer models of phones.
Nevertheless, there are also few drawbacks if the children did not receive a mobile phone. In case of emergencies, children will be able to contact their parents immediately. In addition, certain applications in the mobile phone like the interactive games and dictionary will aid the children growth. Moreover, children will also be able to learn responsibility in taking care of their phone. Finally, children will also be able to communicate with their friends easily.
To conclude, I think that children under the age of 12 should be allowed to own a mobile phone because with proper guidance from parents, I believe that the negative influence will be overcome.
Smoking in public should be banned - KAY
Smoking in public becomes a controversial topic in the world because it affects non smokers as well. Many countries have implemented a ban on public smoking, smokers get fine if they are not follow the rule. However, is there really the need to prohibit smoking in public?
There are three reasons that smoking in public should not be banned. First of all, smoking helps many people to release stress and even improve concentration. For example, many people like to smoke during the short break to get some new ideas. Furthermore, to become a social smoker will help in the career. People has to spend little of time on socialize with peer or employer to getting recognition. Lastly, it is personal right to be able to smoke in public and no one has the right to forbidden it.
On the other hand, against on smoking are well known. Firstly, smoking not only hurt the person who is smoking and also the people surround them. Second hand smoking is extremely serious because it contains hundreds of toxic chemicals and the second hand smokers have the higher chance of getting lung cancer. Besides that, smoker sometime simply throw the cigarette butt on the road and make the road become dirty and it will damage the country’s image. Even worse, when the cigarette butt still burning, if it is thrown on combustibles and it could cause a fire.
In conclusion, I strongly suggested the smoker should also think about other people feeling and health and only smoking in your own space, not in the public.
