阅读理解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 plete 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 understood1.When we use formal English, _______A.we will offend othersB.we will appear educated on important occasionsC.we needn’t pay more attention to grammar rulesD.we can express ourselves more directly and more quickly2.What’s the meaning of the underlined word “precise”?A.clearB.directC.puzzlingD.simple3.Contractions are best used when we are _______A.speaking at a formal meetingB.speaking in publicC.speaking to our friendsD.writing an application (申请) letter4.In speaking, we do not always use plete sentences because ______A.we do not care about grammarB.we do not want to sound stupidC.we can still be understoodD.we don’t want to waste time
