The first and most obvious thing is that a dictionary will (23) you the spelling of a word. If you're not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in alphabetical order--a, b, e, and so on. For example, on a dictionary page the word "poor"--p, o, o, r--comes before "poverty"--p, o, v, e, r, t, y and the word "poverty" comes (24) the word "power"--p, o, w, e, r. The words are always given in alphabetical order.
The second thing a dictionary will tell you is (25) . Most dictionaries give the pronunciation of a word in a special kind of alphabet. This special alphabet is called a phonetic, or sound alphabet. The phonetic spelling will tell you generally (26) a word is pronounced. There are a few different phonetic alphabets. Many dictionaries use the International Phonetic Alphabet to show pronunciation.

Many words have more than one meaning, and a good dictionary will explain all of the word's meanings. For example, in English the common word "get" has over 20 different meanings.

Everything has two sides. One side of SARS is already clear. It is a deadly disease, which causes fear. There were 2601 cases recorded on the Chinese mainland on April 24, according to government figures. Some 115 people have died and numbers keep rising.
But, there's another side.
SARS is a reminder of how fragile (脆弱的)life can be. Suddenly, it's not just the old people who are thinking about death. Everyone now realizes there might not always be a tomorrow.
Li Ping, a Senior 3 student in Taiyuan, Shanxi Province, came into contact(接触)with a suspected(疑似)SARS patient in mid-April. He was told to stay at home for at least two weeks. "Watching TV about more and more SARS patients dying, ! never knew that death could be so close. Life is Valuable and I am going to treasure every single day." he said.
SARS teaches people to be grateful, not only for their own lives, but also for others. Doctors and nurses, for example, have to spend all their time with infected(被感染的)patients. As a result, more than 20 percent of SARS cases in China are medical workers.
Liu Yu, a Senior 2 student of Beijing No. 5 Middle School, wants to be a doctor when he grows up. "Although they certainly know of the dangers, doctors and nurses remain bravely dedicated(致力于)to saving people's lives. I was deeply moved by what they have done. I think they are real heroes." he said.
SARS also teaches sympathy(同情). The past few weeks have been terrible for Chinese people. But there are far worse things than SARS in this world, such as war, earthquakes and murders. Think of the Iraqis, who have been living terrible lives for 20 years. Think of how the Americans felt on 9. 11.
And finally, SARS offers the chance to grow. All different types of people and government officials are joining together to cope with this difficult time. When this passes, China and its people, will have learned great lessons.
The story of Li Ping is given in this passage mainly to ______.
A．tell us the hardship of life
B．tell us the fragility of life
C．tell the cruelty of SARS
D．tell us the joy of life

Crime is a very serious problem in Britain. One sort of crime which particularly worries people is juvenile delinquency—that is, crimes committed by young people. For some years juvenile delinquency had been increasing. There are two main sorts of juvenile crimes: stealing and violence. Most people do not understand why young people commit these crimes. There are, I think, a large number of different reasons.
These crimes are not usually committed by people who are poor or in need. Young people often dislike and hate the adult world. They will do things to show that they are rebels. Also in Britain today it is easier for young people to commit crimes because they have more freedom to go where they like and more money to do what they like.
There are two other possible causes which are worth mentioning. More and more people in Britain live in large towns. In a large town no one knows who anyone else is or where they live. But in the village I come from crimes are rare because everyone knows everyone else.
Although it is difficult to explain, I think the last cause is very important. Perhaps there is something with our society which encourages violence and crime. It is a fact that all the time children are exposed to films and reports about crime and violence. Many people do not agree that this influences the young people, but I think that young people are very much influenced by the society they grow in. I feel that the fault may be as much with our whole society as with these young people.
