英语选择2道 说明原因

第一个选 a
这句话的意思是说：他生活习惯很差,并且他说他习惯了晚睡.
(1)当主句的主语为第一人称时,其后的简短问句应与从句相一致.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,当这些动词后接的宾语从句的否定转移到主句时,其仍属否定句,故其后的简短问句应用肯定式,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?
此类句子的回答同"前否后肯"型反意疑问句一样,如上述后一个句子,若双胞胎已经到了,则回答为"Yes,they have."；若尚未到达,使用"No,they haven't.".
(2)当主句的主语为第二、三人称时,其后的简短问句则应与主句相一致（此时,否定只看主句,与从句无关）.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)但如果主句的时态是过去时等等,疑问句应和主句的人称时态保持一致
第二个选 c
这句话的意思是说：我们完成这项工作还需要额外的5周.这里another five weeks 是作为一个整体时间来看的,并且是一般现在时的一般陈述句,所以选C
