does your step-daughter speak English with a perfect accent
Good question! A perfect English accent? Well as perfect as English is around here ... yes she speaks English will a perfect Brummie accent! For example, she takes the "buzz" to school! And no, it is no longer possible to guess that English is not her first language.
Compared to ... my wife .... who also came to the UK in April 2001 ... whilst she speaks good English, it is easily possible to determine that English is not her first language.
Incidentally, anyone else who has brought, or is bringing, a young child to the UK ..... my step-daughter learnt her English using three different sources. Firstly of course at school, secondly using Argos (and the now defunct Index) catalogue, and thirdly by viewing Cartoon Network and the like for hours!
Argos? The readily-available catalogue has pages and pages of .... pictures and descriptions! A totally free resource helping to convert the visual image ... the pic in the catalogue .. into words.
Cartoon Network? Before coming to the UK she watched cartoons on Thai TV, and surprise surprise the characters spoke Thai! So on coming to the UK and viewing often the same cartoons ... but now the characters spoke English! A great incentive to learn what they were saying.
Taking all those factors into account, my step-daughter's English was really up-to-speed ... normal for her age .... in just a couple of years. And she certainly finished primary school well into the top half of the form as far as English is concerned.
