阅读理解.

     I am an English teacher, with over 15 years' experience of teaching in London. I started

the DailyStep audio email lesson service because I noticed that when I started their English

course, my students' speaking and listening skills were much weaker than their reading and

writing skills. In my view, this is because education in school does not focus enough on

communication skills. DailyStep is designed to remedy this situation by offering more practice

in speaking, listening and vocabulary.

     I am crazy about the English language and it is a real pleasure for me to see the

development of my students' language skills.

      I majored in (以….为专业)law at university and then worked for three years as a

researcher and journalist for Sky television and BBC magazines. I decided to change to

English teaching because of my love of the English language and my wish to move into more

satisfying work.

      Then I qualified (取得资格)as an English teacher in 1992. My first teaching job was at

a language school in Covent Garden, London, where I taught examination classes and

Business English . After two years, I moved to the Nippon Club where I taught General

English and Business English courses for 9 years. I also developed a unique course called

British Society & Culture, covering all areas of British life, such as politics, law, e

ducation & music. At the same time, taught Business, Financial& Law English in the financial

centre of London. My students included staff (工作人员)from banks and law firms.

      As well as running the DailyStep website, I also provide in-company English speech

training for companies in London. If you have an important speech coming up and would like

some information about how I can help you, please email me at jane@dailystep.com.
