Have you ... yet?
你已经……了吗?
A picture-based lesson on the present perfect tense with 'yet'. Four illustrations each introduce a 'Have you ... yet? / When did ...?' question-and-answer pair (read this book, done your homework, he gone, she spoken to him). A table of irregular verbs (cut, put, read, set, shut, do, come, give, swim, take, eat, go, rise, see, speak) reinforces the past and past-participle forms. Written exercises A (write questions and negative answers from past-simple sentences) and B (answer 'What about ...?' questions with 'yet') are transcribed from the textbook. Workbook practice covers completing 'Has he done it yet?' dialogues and writing what you say in three situations. Grammar exercises practise filling in the correct verb forms and correcting mistakes in sentences.
