>> This is me. Bye! >> Bye. >> In the conversation, Linus uses the
present perfect tense to form questions that asked about past experiences. Linus asked have you read
about dinosaurs before? In forming yes/no questions like this,
in the present perfect tense, begin with have or has, then the subject, then
the past participle form of the main verb. Answers for
these types of questions can be short. You can simply say yes I have or
no I haven't. Easy, right? You can also ask different types
of questions using words like who, what, where, when, how, and which. These are all Wh words that can be used to make wh questions. Have you studied dinosaurs? This is a yes no question but where have
you studied dinosaurs is a wh question. To form these types of questions just add WH-words to the beginning
of yes no question forms. The WH-word + have/has, then the subject,
then the past participle. Do you remember Linus's
very last question? That's right. Who have you studied with? This is also a WH-question
that uses the same structure, the WH word, plus have or has, then
the subject, then the past participle. Who have you studied with? Great job.
