What's wrong , Dave ? You look down today .   I didn't pass the English exam . How to learn English well ? Can you give me some suggestions ?   Well , English is a " paper tiger " . Its natural enemy is adequate practice .   I have done a lot of reading comprehension exercises , and I also spend much time in memorizing English words .   I suggest you read English texts aloud every day , and try to speak more . That will be beneficial to cultivate your sense of the language .
