帮忙分析一下句子成分，He.is.about.the.same.age.as.you.还有这是表语从句吗？谢谢啦~~

Answer 1

1.He.主语is.系动词about状语，' 大概" .the.same.age表语.as.you表比较的状语，也可以被认为是补足语；
2.这不是表语从句。可能你对表语从句不清楚，这里稍作扩展：
表语从句
一 定义：
A 表语从句就是用一个句子作为表语。说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。用作表语的从句叫作表语从句，它位于主句中的连系动词之后。可以接表语从句的连系动词由be, look, remain, seem等。
The problem is puzzling. 主语 连系动词 形容词作表语
The problem is when we can get a pay rise. 主语 连系动词 一个句子作表语---表语从句
B 连接表语从句的词有从属连词that、whether、as though(if)；关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词when, where, why, how, however, whenever, wherever等。
He has become a teacher. He has become what he wanted to be ten years ago.
She has remained there for an hour. She has remained where I stood yesterday for an hour.
His suggestion is good. His suggestion is that we should stay calm.
The question is confusing. The question is when he can arrive at the hotel.
who will travel with me to Beijing tomorrow. why he cried yesterday.
how I can persuade her to join us in the party. whether the enemy is marching towards us.
二 注意：
A 表语从句一定要用陈述语序。
False: The question is when can he arrive at the hotel. Right: The question is when he can arrive at the hotel.
B 不可以用if，而用whether 连接表语从句(as if 例外)。
引导宾语从句时可以互换if/whether 位于介词后要用whether
位于句首时要用whether
引导表语从句，主语从句，同位语从句时要用whether
False: The question is if the enemy is marching towards us.
Right: The question is whether the enemy is marching towards us. Right: It looked as if he had understood this question
C 不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。
Right: The question is who will travel with me to Beijing tomorrow. Right: The question is why he cried yesterday.
D that在表语从句中不可以省掉。
表语从句的基本用法
表语从句只能置于主句之后，而主句的动词只能是联系动词。
名词性从句在be等系动词后作表语时被称为表语从句， 例如： The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)// The scissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语)// What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语， that作为表语从句的引导词在该表语从句中不充当句子成分， 不能省略)// That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语)// That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语)
　　注意： “That is why...”是常用句型， 意为“这就是……的原因/因此……”， 其中why引导的名词性从句在句中作表语， 该句型通常用于针对前面已经说明过的原因进行总结， 又如： That is why you see this old woman before you know, Jeanne. 珍妮， 这就是现在这个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异， 说话人对她讲述了其中的原因之后，用这一句来进行概括)。// That is why I came. 这就是我来的原因。
　　下面是两个与“That is why...”形式相似的结构， 它们与“That is why...”结构之间的关系要能够辨析清楚：
　　(1)“That is why...”与“That is the reason why...”同义， 只不过从语法结构上讲， “That is the reason why...”中why引导的是—个定语从句， 将其中的the reason去掉则与“That is why...”结构一样， 例如：
　　That is (the reason) why I cannot agree. 这就是我不能同意的理由。
　　(2)“That is because...”句型中从属连词because引导的名词性从句在此作表语， 这也是个常用句型， 意为“这就是为什么……/因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由， “That is why...”则指由于各种原因所造成的后果， 例如：
　　He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影， 那是因为他得帮助他的妹妹做作业。(第一句话说明结果， 第二句话说明原因)
　　He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影， 因此他昨天晚上没有去看。(第一句话说明原因， 第二句话说明结果)

Answer 2

不是表语从句，用作表语的从句叫作表语从句，它位于主句中的连系动词之后。引导表语从句的词有从属连词that、whether、as though(if)；关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等；关系副词when, where, why, how, however, whenever, wherever等。可以接表语从句的连系动词由be, look, remain, seem等。
这是套用句型 the same +名称 as+某人，about 是大约的意思。

Answer 3

He.主语is.系动词about状语，' 大概" .the.same.age表语.as.you表比较的状语，也可以被认为是补足语

Answer 4

he在这里作主语is是谓语，后面的是表语，这个句子应该是主系表结构，不是表语从句

Answer 5

这显然不是从句啊 有主句才有从句 而且这句子主谓宾齐全的哪里会是从句啊 至于句子成分 挺清楚的啊 哪里有问题 顶多as you可以算个宾补吧
