Because writing has become so important in our culture, we sometimes think of it as more real than speech. A little thought, however, will show w hy speech is primary and writing secondary to language. Human beings have been writing (as far as we can tell from surviving evidence) for at least 5000 years; but they have been talking for much longer, doubtless ever since there have been human beings.
When writing did develop, it was derived from and represented speech, although imperfectly. Even today there are spoken languages that have no written form. Furthermore, we all learn to talk well before we learn to write; any human child who is not severely handicapped physically or mentally will learn to talk: a normal human being cannot be prevented from doing so. On the other hand, it takes a special effort to learn to write. In the past many intelligent and useful members of society did not acquire the skill, and even today many who speak languages with writing systems never learn to read or write, while some who learn the rudiments of those skills do so only imperfectly.
To affirm the primacy of speech over writing is not, however, to disparage the latter. One advantage writing has over speech is that it is more permanent and makes possible the records that any civilization must have. Thus, if speaking makes us human, writing makes us civilized.

How to protect children Web fans from unsuitable material online while encouraging them to use the Internet has long been discussed in the US.
For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as hazard and with good guides, some education, and a few precautions, the wilds of the Internet can be safely navigated. “Kids have to be online. If we tell our kids they can’t be allowed to surf the Internet, we’re cutting them off from their future,” said an expert. Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener”. But this can’t be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet. A few other tips as follows:
Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
Ask your child what he or she has been doing and about any friends they make online.
Tell your child not to give online strangers personal information, especially like address and phone number.
And tell your children never to talk to anyone they meet on line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals and anaesthetics. Patients do riot often believe they really need surgery- cutting into a part of the body as opposed to treatment with drugs.
In the early year of the 20th century, there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Cloyed blood vessels can be clean out, and broken ones mended and replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation.
The scope of surgery has increase remarkable in the past decades. Its safety has increased, too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example, to certain types of birth defects in new born babies, and at the other end of the scale, to life-saving operation for the octogenarian .The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks.
One of the most revolutionary areas of modern surgery is that of organ transplants. Until a few decades ago, no person, except an identical twins, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful.
“Spare parts” surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if the doctors say to you: “Yes, l think it is possible to operate on you for this condition”.

Today, compared with 1910 _.

May 7, 1840 was the birthday of one of the most famous Russian composers of the nineteenth century Peter Illich Tchaikovsky. The son of a mining inspector, Tchaikovsky studied music as a child and later studied composition at the St.Pertersburg Conservatory. His greatest period of productivity occurred between 1876 and 1890, during which time he enjoyed the patronage of Madame von Meck, a woman he never met, who gave him a living stipend of about $1,000.00 a year. Madame von Meck later terminated her friendship with Tchaikovsky, as well as his living allowance, when she, herself, was facing financial difficulties. It was during the time of Madame von Meck’s patronage, however, that Tchaikovsky created the music for which he is most famous, including the music for the ballets of Swan Lake and The Sleeping Beauty.
Tchaikovsky’s music, well known for its rich melodic and sometimes melancholy passages, was one of the first that brought serious dramatic music to dance. Before this, little attention had been given to the music behind the dance. Tchaikovsky died on November 6,1893, ostensibly of cholera, though there are now some scholars who argue that he committed suicide.

Not very long ago, when people needed to find a job, there were several possible steps. They might begin with a look through the classified ads in the newspaper. They could go to the personnel office at various companies and fill out an application, or they could go to an employment agency. They could even find out about a job opening through word-of-mouth - from another person who had heard about it.
These days, job hunting is more complicated. The first step is to determine what kind of job you want (which sounds easier than it is) and make sure that you have the right education for it. Rapid changes in technology and science are creating many professions that never existed until recently. It is important to learn about them because one might be the perfect profession for you. The fastest- growing areas for new jobs are in computer technology and health services. Jobs in these fields usually require specific skills, but you need to find out exactly which degrees are necessary. For example, it may be surprising to learn that in the sciences, an M.S. is more marketable than a Ph.D! In other words, there are more jobs available for people with a Master of Science degree than for people with a doctorate (however, people who want to do research still need a Ph.D.) How do people learn about "hot" new professions? How do they discover their "dream job"? Many people these days go to a career counselor. In some countries, job hopping has become so common that career counseling is now "big business". People sometimes spend large amounts of money for this advice. In Canada and the United States, high school and college students often have access to free vocational counseling services on campus. There is even a career organization, the Five O'Clock Club, which helps members to set goals. Members focus on this question: what sort of person do you want to be years from now? The members then plan their career around that goal. All career counselors - private or public - agree on one basic point: it is important for people to find a career that they love. Everyone should be able to think, "I'm having such a good time. I can't believe they're paying me to do this.”

It can be inferred from the passage that what determine one’s success in job hunting is     .

Ostriches are the largest and heaviest birds on earth. They can grow to be as tall as 9 feet and can weigh as much as 250 pounds. Even though they have wings, they cannot fly. Instead, ostriches have long, powerful legs that help them to run very fast when they feel threatened. Ostriches use their wings to move themselves forward and to help them change direction. Ostriches are native to Africa, where they still live in desert areas and dry, open grasslands called savannah. Ostriches can also be found in zoos all over the world. Humans have domesticated ostriches, so now ostriches live on farms in over a dozen countries, including the United States, China, India, Japan, Brazil and Costa Rica. They are raised for their meat, skin, and feathers. Ostriches like to live in small groups called herds. The male ostrich is called a rooster; the female, a hen. Baby ostriches are called chicks.
