英语语法疑惑

原意为it is (no) good doing sth.
这是个句型。
do you consider it any good trying again?
it 这里是CONSIDER的宾语，而后面充当it 宾语补足语。
此句也可以加上IS，do you consider it is any good trying again? 这个时候CONSIDER后面是宾语从句

consider般不接不定式的

详细的：《用法》
consider作动词时主要有以下四种用法:

一、作"思考"、"考虑"(=think about)解,后面可接动名词、由"how, what等+动词不定式"或者从句作宾语.但要特别注意,consider后面不能直接跟动词不定式作宾语。例如:

①We are considering going to Hainan for the Spring Festival.我们在考虑赴海南过春节。

②He has never considered how to solve the problem. 他从未考虑过如何解决那个问题。

③Do you consider that we can finish the project ahead of time?你认为我们能提前完成这个项目吗?

二、consider v.还可作"顾虑到"、"顾及"、"体谅"(=take into account)解。这时其后用名词或动名词作宾语。例如:

①All of you should consider the feelings of other people. 你们必须顾及到他人的感情。

②Although he has made such a stupid mistake, you should consider his youth.尽管他犯了那样愚蠢的错误,你应该体谅他还年轻。

三、作"认为"、"以为"、"觉得"(=be of the opinion, regard as)解时,后面多接宾语从句,这时一般不接动名词作宾语。例如:

①I consider that he is fit for the position of the manager. 我认为他胜任经理的位置。

②We consider that you are not to blame.我们认为这不是你的错。

③He has never considered the fact that his family is not very rich.他从未考虑过他家并不富裕这一事实。

consider作"认为"解时,后面还可以接一个宾语和一个动词不定式作宾语补足语,构成复合宾语结构,但这种结构的动词不定式主要是"to be+名词/形容词";有时也可以是其它不定式,不过这种不定式多用完成时。例如:

①We always consider him to be a weak leader. 我们一直认为他是个能力不强的领导。

②They consider Jim (to be) the cleverest boy in their class. 他们认为吉姆是他们班最聪明的学生。

③I consider her to have done wonderfully in the final exam. 我认为她在期末考试中表现得非常出色。

注:consider作"认为"解时,后面偶尔也出现接不定式作宾语的情况,不过这时大都用形式宾语it,而将真正的宾语后移。例如:

Do you consider it wise to interfere?你觉得干预是明智的吗?

四、固定结构"consider... as/ to be+名词/形容词"多侧重于表示经过思考"认为……是……"。例如:

①We consider his suggestion as having possibilities. 我们认为他的建议具有可行性。

②They considered the plan as reasonable. 他们认为这个计划是合理的

Do you consider it any good______again?
A, to try B, trying C, for you to try
疑惑：
1,有人说 it any good_trying_____again
是it is no good doing 的变化 那么这个no 怎么一下子转换为 any拉 ?
转换时 怎么把is 省去了 呢？
2 为什么不能用不定式呢？
请解释
答：It is no good doing sth.
-> Is it any good doing sth? 疑问句用any很常见的。
能用动名词作直主的句型不多，就只It is no good/ use doing sth. 这少数几个。已经习惯成自然了。
->I think (that) it is no good doing sth.
-> Do you think (that) it is any good doing sth?
consider=think
Do you consider it any good doing sth.? 这是一个简单句。
Do you consider (that) it is any good doing sth.? 这是一个复合句。
两句意思相同。

1.it no good doing sth 句中good是名词，好处的意思，在疑问句中no成了any 这个不需要解释了吧？然后is 在这里去掉因为在疑问句中可以这样，即使是形容词。
2.同第一条解释

你好。是单词的词性决定用doing或者to do:
Do you consider it any good(good是名词) TRYING again?==Do you consider it good（good是形容词） TO TRY again ？
