Article: The Internet has become a part of our everyday life and there is nothing we can do without it.It is a means of communication as well as a good way of relieving and having fun.No matter in what place of the world,the Internet is the same for every one of us. If we hope to improve our knowledge or look for a certain piece of information, the Internet is the perfect tool for our need.If we do not have the time to shop, ordering online is the solution to our problem.The Internet is very useful to most people. There is no doubt that the Internet also has some bad points.I'm speaking about the harmful information,which may come up in the most unexpected paces.You can sometimes come across violence,presented to the public as a very normal way of expressing beliefs.An intelligent person will always be able to tell apart right and wrong, but what can we do to help the teenagers and children? This sort of information is a cause of many of the violent incidents in schools. There are few organization that monitor the Internet and the information on it.They cannot possibly get rid of all the bad things on the Internet. So should the Internet be censored for the protection of children? My belief is that parents are the ones who should be to blame for what their children ale doing on the Internet.

Article: Britons spend as much as nearly five hours a week keeping their homes clean, a survey found. Kitchens are cleaned most often, while doing the oven and windows are the least popular jobs. In total, they spend just over PS1 billion a year on products to keep the dirt at bay -- almost PS40 per household. Market analyst Mintel found a clear division of labour. While the average Briton spends 4 hours, 40 minutes cleaning their home each week, men spend just 3 hours, 53 minutes compared to 5 hours, 25 minutes for women. And while seven in ten women say they do most of the cleaning, this falls to four in ten for men. Confirming many parents' feelings, only one in five adult children and over living at their parents' home helps with cleaning chores, with children under 18 doing even less. Last year, the household cleaning market was worth PS1.06 billion, which equates to annual spending of PS39.89 per household. Those looking for the cleanest homes in the country should head to Scotland, where people spend an average of five fours, 6 minutes, which is closely followed by East and West Midlands at five hours, 1 minute. In comparison, the least number of hours spent in cleaning is spent in the southeast/East Anglia at four hours, 18 minutes. The southwest and Wales stand at four hours, 46 minutes, the northwest four hours, 44 minutes, and Yorkshire and the Humber four hours, 21 minutes. According to Richard Caines, Mintel's senior household care analyst, men still lag women in the household cleaning stakes and spend on average an hour and a half less time cleaning their home, suggesting an opportunity for a campaign to encourage more cleaning by men to helpredressthis imbalance. The number of households that need cleaning is continuing to grow, but pressure on time from increasingly busy lives limits the number of hours people are willing or able to spend cleaning their homes. This means the market will see an increasing focus on easy-to-use, but effective hard surface cleaners and cleaning equipment. Such products can help encourage more cleaning to be done in less time, but as well as focusing on more convenient products, cleaning brands can also inject an element of fun into campaigns through encouraging a more shared approach that involves the whole family. This will also help to address the gender imbalance and get older children to make more of a contribution to cleaning.
Question: In which area do people spend the most time cleaning their home each week?
Options: (A) Scotland. (B) Wales. (C) Yorkshire and the Humber. (D) East and West Midlands.

Article: Every person leaves a footprint. That's what I learnt when I started to work as a private investigator 10 years ago.People pay restaurant bills with their bank card,check into hotels or travel around. In every case,they leave a trace.And because of this,I'm able to track them down even when they don't want to be found. The first thing I do when I want to find out where someone is staying is to go to the neighbourhood where he used to live.It's human nature to tell stories--which is why neighbours will tell me all they know when I ring at their houses.Sometimes,someone even talks about his friend's dishonesty.Then I produce a pattern of my subject's life:if he likes to have a holiday in Spain or in Italy,if he prefers two- or three- star hotels and where he might hide his assets .When I've got this life pattern,I start my rescarch. Nine times out of l0,I find the people I'm looking for.I once investigated a lorry supplier who owed PS500,000 to a subcontractor .The subcontractor wanted to find out if it was worth bringing charges against the supplier.I found out the supplier had moved assets to his son,who founded a new company offering the same product.It was a11 done within the law.There was no money to be got from that operation. However, I asked the son if I could speak to his father and he told me that his parent was on a long holiday in Spain and wouldn't be back for a while.It didn't take me long to find out that the father wasn't in Spain. I went back to the son and this time he told me that his father might be in Bulgaria,and I found him doing winter sports in a beautiful mountain area.He was 1iving in a big house on a 1arge piece of land he had bought for ie 400,000.This was exactly the kind of asset my customer was loooking for.
