There are plenty of people in the UK for whom even Basic English is a problem. According to the survey, 726,000 people in England and Wales said they could not speak English well, and another 138,000 said they did not speak it at all.

Ling, 40, who arrived five years ago from China,, found it difficult to learn English. “After I came here, I was at home for the next three years. It took me longer to learn as I was very busy with my children.” Eventually she was able to begin taking classes and now speaks good conversational English. But even with classes, it can be a long process to pick up the language.

Age is the most important factor in language study, said Mila Vulchanova, professor of linguistics (语言学) at the Norwegian University of Science and Technology. “There is a key time in language learning, which is biologically determined. So the younger the immigrants(移民)， the better. Since this decline is only gradual, teenagers are at an advantage over adults,”he said.

There are a number of systems for grading English. The government expects immigrants to reach “ESOL Entry 3”or “B1 level” in Scotland, before they can be given citizenship. It means to be able to hold a confident conversation and it might take 360 hours of study to achieve.

George Osborne, the UK chancellor(财政大臣)，said in June that benefit claimants (申请救济金者) who don’t speak English will have their benefits cut if they fail to attend language courses. Huan Japes, deputy chief executive of English UK, a trade body for language colleges, said it needed 360 hours-----120 hours for each of three stages ---- to get to the result the government expected benefit claimants to reach.

“Using 120 hours, for each stage of English fluency(流利)，is a rather traditional way to course book learning,” said Dr Elaine Boyd, head of English language at Trinity College London. “If someone is really highly motivated, they can learn really quickly. It’s common for children under the age of 11 to be fluent in about six months.”
