If you've listened to our previous Critical Verb lessons, our fourth installment won't contain anything terribly surprising. Rather than a surprise appearance by David Bowie and impromptu studio versions of China Girl (working on it...), we just review the verbs "to eat", "to want" and "to give". So there is a lot to review here, but also some new stuff as well. In particular, we'll teach you how to put verbs into the past tense, and negate them once they're there.Learning Cantonese? We've come a long way since our first Cantonese lesson. Back then we started with the tones and learned some basic phrases in Cantonese before moving on to simple sentences using adjectives. After that we moved on to high-frequency nouns and then finally more complex sentences involving verbs. That's a lot of ground to cover, so feel proud about how much you've done. And be sure to come back later this week when our first dialogue-based lesson makes its debut.
