请帮我分析一下这句话的语法，谢谢！

我想知道整个句子的结构，这不是一个问句吗？怎么是主、谓、宾顺序？谢谢！

Answer 1

特殊疑问句的结构有两种：
1. 最常见的特殊疑问词+一般疑问词（暂且这样叫吧）+主谓+,,.
What is your name?
Why do you like English?

2. 特殊疑问词就是主语，这时候就是陈述语序了
who wants water?
who likes English?

你的句子就是第二种

Passage Two

It's always fun to write about research that you can actually try out for yourself.

Try this: Take a photo and upload it to Facebook, then after a day or so, note what the URL link to the picture is and then delete it. Come back a month later and see if the link works. Chances are: It will.

Facebook isn't alone here. Researchers at Cambridge University have found that nearly half of the social networking sites don't immediately delete pictures when a user requests they be removed. In general, photo-centric websites like Flickr were found to be better at quickly removing deleted photos upon request.

Why do "deleted" photos stick around so long? The problem relates to the way data is stored on large websites: While your personal computer only keeps one copy of a file, large-scale services like Facebook rely on what are called content delivery networks to manage data and distribution. It's a complex system wherein data is copied to multiple intermediate devices, usually to speed up access to files when millions of people are trying to access the service at the same time. But because changes aren't reflected across the content delivery networks immediately, ghost copies of files tend to linger for days or weeks.

In the case of Facebook, the company says data may hang around until the URL in question is reused, which is usually "after a short period of time", though obviously that time can vary considerably.

30. What does the speaker ask us to try out?

31. What accounts for the failure of some websites to remove photos immediately?

答：主语：What
谓语：accounts for
宾语 the failure
定语1. of some websites
定语2. to remove photos immediately
析：定语1，2都是修饰宾语the failure的
介词of不是with,不能跟复合宾语，所以不能说to do sth.是宾语补足语。
说它是方式状语更是不通。
一开始我以为是in removing photos immediately 之误，
后来发现，这个表达是正确的。我们有谓语fail to do sth. 表示没能做成某事。
所以就有名词词组sb's failure to do sth. 某人的没能做成某事
只不过这里不是sb's 而of some websites,
failure与to do sth.隔得较远了，所以理解起来有一定的困难。

关于楼主的追问，有点意思。不是所有的特殊疑问句都是主谓倒装的。如果特殊疑问词本身在句子中作主语，因为它要放在句首，就不可能倒装了，如：
What is on the desk?
Who is there?
Who likes English best in your class?
