第一個(gè)選 a
這句話的意思是說：他生活習(xí)慣很差,并且他說他習(xí)慣了晚睡.
(1)當(dāng)主句的主語為第一人稱時(shí),其后的簡(jiǎn)短問句應(yīng)與從句相一致.例如：
I expect our English teacher will be back this weekend,won't she/he?
We suppose you have finished the project,haven't you?
值得注意的是,當(dāng)這些動(dòng)詞后接的賓語從句的否定轉(zhuǎn)移到主句時(shí),其仍屬否定句,故其后的簡(jiǎn)短問句應(yīng)用肯定式,而非否定式.例如：
I don't believe that he can translate this book,can he?
We don't imagine the twins have arrived,have they?
此類句子的回答同"前否后肯"型反意疑問句一樣,如上述后一個(gè)句子,若雙胞胎已經(jīng)到了,則回答為"Yes,they have."；若尚未到達(dá),使用"No,they haven't.".
(2)當(dāng)主句的主語為第二、三人稱時(shí),其后的簡(jiǎn)短問句則應(yīng)與主句相一致（此時(shí),否定只看主句,與從句無關(guān)）.例如：
Your sister supposes she needs no help,doesn't she?
You thought they could have completed the project,didn't you?
They don't believe she's an engineer,do they?
She doesn't expect that we are coming so soon,does she?
(3)但如果主句的時(shí)態(tài)是過去時(shí)等等,疑問句應(yīng)和主句的人稱時(shí)態(tài)保持一致
第二個(gè)選 c
這句話的意思是說：我們完成這項(xiàng)工作還需要額外的5周.這里another five weeks 是作為一個(gè)整體時(shí)間來看的,并且是一般現(xiàn)在時(shí)的一般陳述句,所以選C
