    優(yōu)質(zhì)解答
    1. A your sister must be at home. 這里MUST表推測,相當(dāng)于your sister is at home. 反義疑問句,前肯后否,所以用isn't
    2. B. they had to catch the early bus 這里had to 是必須的意思,過去時態(tài),用do的過去時態(tài),前肯后否,所以用didn't
    3. B He must have been abroad,這里MUST表推測,相當(dāng)于He has been abroad.反義疑問句,前肯后否,所以用hasn't
