18．Web logs-"blogs"for short-are very popular among young people．Blogs are used to post thoughts，opinions，photos，and other materials on the web for the online community to read．Some bloggers have their own websites； others post their blogs on one of many blog-hosting sites．Blogs，a source of news，however，are not fixed communications．Postings can be added and replied to on a continuing basis．
    While children may enjoy"blogging"，it can be dangerous．Online predators who search blog-hosting sites for potential targets，can learn personal information about the children who post blogs．Furthermore，predators are always able to contact the child who posted the blog by sending a message through the website．
    Parents should be careful that their children don't get into any danger．To protect them，they can do the following things：

◇Make sure your children know never to let out personal information on the Internet，whether through a blog，chat room，or e-mail．Even seeminglyinnocuousinformation-such as the mascot （吉祥物） of their school-can help strangers determine where they live．
◇Consider equipping monitoring software that will enable you to monitor how the computer is being used and what your child is doing on it．
◇Remind your children that they should not contact anyone online whom they don't know in person，even if the person has a blog that looks interesting to them．If your child has posted a blog on the Internet，check the content regularly．

17．Did anyone find that the names of"Great Britain"，"the United Kingdom"，"England"and"the British commonwealth"have the same meaning？Strictly speaking，these names all refer to something different．None of them are exactly the same as any of the others．
The British isles refer to the main islands and several thousand small ones as well，which you can see on the map．Great Britain，or Britain，refers to the larger of the two main islands．But the word"Britain"is often used as a short form for the United Kingdom or you call it the UK．
Now as for England，it refers simply to the largest of the three countries on the island of Great Britain．The United Kingdom is the name of the state and the official name of the country，which many people popularly refer to England．
　　Finally，the Britain commonwealth is the usual name for what is left of the British Empire．This change shows the weakening of the British Empire and the rising of the national liberation movements throughout the world today．

13．There is an English saying that"Laughter is the best medicine．"Until recently，few people took the saying seriously．Now however，doctors have begun to look into laughter and the effects it has on the human body．They have found that laughter can really improve people's health．
Tests were carried out to study the effects of laughter on the body．People watched funny films while doctors checked their hearts，blood pressure，breathing and muscles．It was found that laughter has similar effects to physical exercise．It increases blood pressure，makes the heart beat more quickly and makes people breathe deeper； it also works on several groups of muscles in the face，the stomach，and even the feet．If laughter exercises the body，it must be beneficial．
　　Other tests have shown that laughter appears to be able to reduce the effects of pain on the body．In one experiment doctors produced pain in groups of students who listened to different radio programs．The group that tolerated （忍耐） the pain for the longest time was the group that listened to a funny program．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain．

12．During the 19th century，scientists found that when certain parts of the brain of a person were hurt，he would lose the power of doing certain things．And so，people thought that each part of the brain does a different job．But modern research has discovered that this is not so，for it is not easy to show exactly what each part of the brain does．
In the past fifty years there has been a great increase in the amount of researches done on the brain．Scientists have found out the way the brain works is not so simple as people in general may think．Chemists tell us that about 100，000 chemical changes take place in the brain every second．Some recent researches also suggest that we can remember everything that happens to us．We may not be able to think of the thing that happens to us．We may not be able to think of the things we have heard and seen，but they're all kept there in the storehouse of the human mind．
Earlier scientists thought that the power of one's brain got weaker and weaker as one grows older．But it is now thought that that is not true．As long as the brain is given plenty of exercise，it keeps its power．It has been proved that an old person who has always been active in the mind has a quicker mind than a young person who has only done physical work without using much of his brain．
