Successful Language Learners
1. Some people seem to have a knack for learning languages.They can pick up new vocabulary, master rules or grammar,and learn to write in the new language more quickly than others.They do not seem to be any more intelligent than others,so what makes language learning so much eas- ier for them?Perhaps if we take a close look at these successful language learners,we may dis- cover a few of the techniques which make language learning easier for them.
2. First of all,successful language learners are independent learners.They do not depend on the book or the teacher;they discover their own way to learn the language.Instead of waiting for the teacher to explain,they try to find the patterns and the rules for themselves.They are good guess-ers who look for clues and form their own conclusions.When they guess wrong,they guess again. They try to learn from mistakes.
3. Successful language learning is active learning. Therefore,successful learners do not wait for a chance to use the language;they look for such a chance.They find people who speak the lan-guage and they ask these people to correct them when they make a mistake.They will try anything to communicate .They are not afraid to repeat what they hear or to say strange things;they are willing to make mistakes and try again .When communication is difficult,they can accept information that is inexact or incomplete.It is more important for them to learn to think in the language than to know the meaning of every word.
4. Finally,successful language learners are learners with a purpose.They want to learn the language because they are interested in the language and the people who speak it.It is necessary for them to learn the language in order to communicate with these people and to learn from them. They find it easy to practice using the language regularly because they want to learn with it.
5. What kind of language learner are you?If you are a successful language learner,you have probably been learning independently,actively,and purposefully. On the other hand,if your language learning has been less than successful,you might as well try some of the techniques outlined above.
Successful language learners derive conclusions______.
A.to discover sentence patterns and grammatical rules
B.to expand vocabulary
C.to use the target language
D.to encourage unsuccessful language learners to learn independently,actively and purposefully
E.from clues
F.to say strange things

[填空题]
Dear Client,
Office Angers Agency is advising businesses to plan as far ahead as possible to ensure guaranteed staff cover during holiday periods. There is now a serious shortage of skilled secretarial and administrative staff and this is expected to get worse over the next twelve months.
Businesses which require staff with experience of specialist computer applications are the most at risk. You are advised to contact our agency well before the staffs are actually needed to be certain of filling gaps with adequately trained personnel. If you don’t, it’s almost certain that you will be left without the skills needed to keep your office running smoothly.
The reason for the shortage of secretarial staff appears to be a combination of two factors. There has been an increase in the demand for secretarial services over the last few years, and at the same time there has been a lack of students deciding to choose secretarial studies.
