Few people realize that there is a big difference between formal English and informal English. Formal English is used for most writing, and often in public speaking and formal meetings. It pays close attention to grammar rules, because if we use proper grammar, our meaning is often more precise. Also, on important occasions, we do not want to appear uneducated or to offend (冒犯) others, so we are very careful about how we speak. Informal English is used in speaking or writing to our friends and family. It often does not pay such close attention to grammar rules, because when we speak or write to them, we want our words to flow quickly. Also, with our friends and family, we are usually not so worried about appearing uneducated or about offending them by how we write or speak.
A big difference between formal and informal English is the use of contractions. A contraction is where we make a word shorter or where we put two words together and take away some of the letters. For example, instead of saying “do not”, many people say “don’t”. Using contractions in our speech is fine because it sounds natural, especially when we speak to our friends. In formal writing, however, contractions are usually avoided because people might think that you have made a mistake, or that you do not know proper grammar.
In the same way we might make words shorter, in informal English we often make sentences shorter as well. For example, if someone asks you your name, you will likely answer with one word: your first name. However, in formal English we usually use complete sentences. For example, we might write “My name is John”. In most speaking, we may not need to use every word in a sentence because the person we are speaking to will probably still understand us. In most writing, however, every word in a sentence must be written out in order to make sure that we can be understood.
【小题1】When we use formal English, _______.

 PART FOUR  WRITING

  SECTION A

  Directions: Read the following passage. Complete the diagram by using the information from the passage.

  Write NO MORE THAN THREE WORDS for each answer.

One of the definitions of a symbol is that it is "something that stands for something else. " We can divide symbols into three kinds: the conventional, the accidental, and the universal symbol.

    The conventional symbol is the best known in everyday language., The letters t-a-b-1-e stand for the thing "table" we see, touch, and use. But there is no inherent (内在的) relationship between the meaning and its letters or sound. The only reason the word symbolizes the thing is the convention of calling this particular thing by a name. After being repeated over and over, the word is accepted in the language.

     Besides words, pictures also act as symbols. A flag, for instance, may stand for a specific country, and yet there is no inherent connection between the specific colors and the country for which they stand. It has been accepted after repeated uses.

     The opposite to the conventional symbol is the accidental symbol. Supposing that someone has had a saddening experience in a city, he will easily connect the name with a mood of sadness when hearing its name, just as he would connect it with a mood of joy had his experience been a happy one. Obviously, there is nothing in the nature of the city that is either sad or joyful. It is the individual experience connected with the city that makes it a symbol of a mood. The connection between the symbol and the experience symbolized is entirely accidental.

     The universal symbol is one in which there is an inherent relationship between the symbol and the symbolized. Take, for instance, the symbol of fire. Fire gives us the impression of power, of energy, and of lightness. When we use fire as a symbol, we describe the inner experience characterized by the same elements the mood of energy, lightness, movement, etc.

     The universal symbol is the only one in which the relationship between the symbol and that which is symbolized is not coincidental (巧合的), but inherent. It can be called universal because it is shared by all men, in contrast not only to the accidental symbol, which is entirely personal, but also to the conventional symbol, which is shared by the people of the same convention.

A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. All computer viruses are manmade. Here are some virus prevention tips.

Do not open any files attached to an e-mail from an unknown, suspicious or untrustworthy source.

Do not open any files attached to an e-mail unless you know what it is, even if it appears to come from a dear friend or someone you know. Some viruses can replicate（复制） themselves and spread through e-mail. Better be safe that sorry and confirm that they really sent it .

If you are uncertain, don’t download the file at all or download the file to a floppy（软盘）and test it with your own anti-virus software.

Update your anti-virus software regularly. Over 500 viruses are discovered each month, so you’ll want to be protected. These updates should be at least the products virus signature files. You may also need to update the product’s scanning engine as well.
