比如下面的句了:
What do you think his motives were in helping us?你认为他帮助我们是出于什么动机?
Who do you think will be the next Prime Minister? 你认为下届首相会是谁呢?
Who do you think should win the Academy Award for Best Director this year? 你认为今年谁会获得奥斯卡最佳导演奖?
这些句子是复合句呢?还是带有插入语的简单句?即句中的 do you think 是插入语还是主句?谢谢老师!
do you think 有两种基本用法,概括起来就是:一、后跟宾语从句,构成复合句;二、用作插入语。
▲一、Do you think 后跟宾语从句时,它只能跟 that 引导的句子,宾语从句必须是一个陈述的内容,that 经常省略。例如:
Do you think you can climb that steep cliff? 你以为你能爬上那座悬崖峭壁吗?
Do you think this hat and your coat go together? 你认为这顶帽子和你的衣服协调吗?
Do you think a cure will be found for cancer? 你觉得能找到治疗癌症的方法吗?
Do you think this trunk will hold all our clothes? 这个箱子你想能装得下我们所有的衣裳吗?
Do you think you'll get the work finished on time? 你认为你的工作可以如期完成吗?
Do you think football is an exciting sport? 你认为足球是一种激动人心的运动吗?
Do you think I'd believe a story like that? 你以为我会相信这样的谎话?
Do you think the proposal is acceptable? 你认为这个建议可接受吗?
▲Do you think 之后不能跟有任何疑问的从句:包括if/whether(表示一般疑问概念“是否”)引导的宾语从句,以及wh-word(表示特殊疑问概念)引导的宾语从句。以下都是错误的表达:
*1. Do you think whether they will succeed? 你认为他们会成功吗?
*2. Do you think if she will come to our party? 你认为她会来我们的聚会吗?
*3. Do you think what will happen next? 你认为接下来会发生什么?
*4. Do you think who will win the first prize? 你认为谁会获得一等奖?
*5. Do you think how the war broke out? 你认为那场战争是怎样爆发的?
*6. Do you think how much this radio will cost? 你认为这台收音机值多少钱?
*7. Do you think when China will host the World Cup? 你认为中国何时会举办世界杯?
*8. Do you think where we can get this machine? 你看我们在哪儿能搞到这种机器?
*9. Do you think why most of children like cartoon? 你认为为什么孩子们喜欢卡通?
*10. Do you think who is fit for the job? 你认为谁适合这项工作?
为什么上述句子是错误的?从逻辑上讲,因为Do you think 本身就是一个一般疑问句,其宾语从句不能再出现任何疑问的概念,只能是表达陈述的内容。
▲二、Do you think 遇到特殊疑问句时,只能用作插入语。即把do you think 放在wh-word之后,句子语序按照陈述语序。从本质上讲,有没有do you think 作插入语,并不影响句子的意思,省去无妨,只需要调整句子的语序而已。如:句1,2,去掉do you think,语序不变,因为What和Who分别作主语。句3,去掉do you think ,需要在the war之前加did,broke out变为原形,还原成原来的特殊疑问句。以此类推,举一反三。
1. What do you think will happen next? 你认为接下来会发生什么?
2. Who do you think will win the first prize? 你认为谁会获得一等奖?
3. How do you think the war broke out? 你认为那场战争是怎样爆发的?
4. How much do you think this radio will cost? 你认为这台收音机值多少钱?
5. When do you think China will host the World Cup? 你认为中国何时会举办世界杯?
6. Where do you think we can get this machine? 你看我们在哪儿能搞到这种机器?
7. Why do you think most of children like cartoon? 你认为为什么孩子们喜欢卡通?
8. Who do you think is fit for the job? 你认为谁适合这项工作?

同意刘老师的分析,这位网友的所列句子中的 do you think 均为插入语。相关理论依据有《张道真英语语法大全》第374节:
374 有些问句中可插入 do you think, do you guess之类插入语,这时后面部分要用陈述句语序:
What do you think we should (不要说 should we) do?
(=What, in your opinion, should we do? )
Where did they tell you he was going?
Which do you guess is the better?
How do you say we can settle the problem?
