英语--单项选择题
1.You and I could hardly understand each other,_______?
A.could I
B.couldn't you
C.could we
D.couldn't we
课本答案选D..为什么?hardly不是表否定的吗,那么反义疑问句后面应该用肯定啊..答案为什么不是C...
2.The modern automobile is a _________ composed of more than 14,000 parts.
A.complex technical system.
B.complex technical system that
C.system of complex technical
D.system is technically complex
课本答案选A...为什么?为什么不选B呢?

2/composed of相当于是分词词组直接做后置定语,若是完整的定语从句应为“that is composed of”加上is,构成完整的谓语.所以不选B.
1/该题答案错误,请看以下第四点,若是含有否定意味的never,hardly,都该用肯定式,因为句意已经被否定.
你有很好的“怀疑一切”的态度,“不唯书”,很好,赞!
反义疑问句复习一下：
1. In the present tense, if the subject is 'I', the auxiliary changes to 'are' or 'aren't'. 现在时,句中主语为I则用 'are' or 'aren't'
I'm sitting next to you, aren't I?
2. With 'let's', the tag question is 'shall we'. let‘s开头,用shall we
Let's go to the beach, shall we?
3. With an imperative, the tag question is 'will you'.
Close the window, will you?祈使句用will you
4. We use a positive tag question after a sentence containing a negative word such as never, hardly, nobody.句中含有否定以为词,则用肯定式.
Nobody lives in this house, do they?
You've never liked me, have you?
5. When the subject is nothing, we use 'it' in the tag question. 主语缺失,用it
Nothing bad happened, did it?
6. When the subject is nobody, somebody, everybody, no one, someone, or everyone, we use 'they' in the tag question.
主语是nobody, somebody, everybody, no one, someone, or everyone,用they
Nobody asked for me, did they?
7. If the main verb in the sentence is 'have' (not an auxiliary verb), it is more common to use 'do' in the question tag. 如果have不是助词,表达“有”的含义,用“do”
You have a Ferrari, don't you?
8. With used to, we use 'didn't' in the tag question.
You used to work here, didn't you?句中有used to,则用didn't
9. We can use positive question tags after positive sentences to express a reaction such as surprise or interest. 表达惊讶,可以在前句肯定时,仍然用肯定
You're moving to Brazil, are you?
