有關 practical english usage 一書

1)我覺得呢本書好得^^
2)好多基本ge知識, grammar....佢都有
3)level就唔係咁高, 佢有3個level, 我小學4年班開始用，一年學一本。不過佢d野真係好實用，如forming nouns, tenses, comparision of adjectives, pronouns, relative pronouns, prepositions, agreement, question tags , antonyms, synonyms, homonyms等等。
4)佢冇教日常會用錯既usage，可昔。但係佢好清楚咁解比你聽，跟住有ex.做。

5)oxford practical grammar，托福語法教程呢兩本都唔錯。尤其係托福，每一題ge答案都解釋得明明白白。
