What is the English problem with the man?

W: What do you find hardest in English?
M: I find listening really hard.
W: Well, you just need lots of practice . The more you listen to English. The easier it becomes.
M: That’ s easier said than done !
W: Why don’t you buy a radio? Then you can listen to Radio Beijing or BBC English pro- grammes on the radio.
M: Do you think that would help?
W: Of course. And why not buy some English tapes and some books to go with them? I’ m sure you’ll find them useful.
M: Yes, that’ s a good idea. But I have another difficulty. My written English isn’t very
good, either.
W: Oh, well for that, you’ d better find an English pen friend.
