英语语法超级纠结中
1 He was excited To such an degree that he couldn’t sleep last night.
改成so/such...that 是
To such an degree was he excited that he couldn’t sleep last night.
2 The boy is interested in such a lovely toy that his parents decide to buy it for him.
若这句要改成such ...that倒装的话 是
Such a lovely toy is the boy interested in that his parents decide to buy it for him.
还是
In such a lovely toy is the boy interested that his parents decide to buy it for him.
之所以有这样的疑问是因为 1中的 介短To such an degree 是做句子的程度状语的,为一整体,一块移至句首.而2中的 be interested in是个固定用法,到底in要不要也移到句首呢?be interested in sth 虽为固定,但就句子成分划分,in sth 是不是也是做谓语 be interested的状语的呢?到底这种 be+ adj+ perp sth 是如何划分的?“be+ adj+ perp是 谓语 sth是 宾语?”还是“ be+ adj 是谓语 perp sth 是状语” 另外还有 ,那定语从句中介词怎么能即可放在that/which前面,也可放在定语从句的后面呢?
这里一直很晕菜,可能是我太笨,理解能力不够.谁能帮我仔细讲解下.

答：你的问题很好,但又很不好 回答.
注意到我上面打的字了吗?我故意将一个意群拆开了.就是这个“不好”,是与“回答”结合紧密还是和“很”结合紧密呢?应该是前者.所以翻译成英语时,这两个“好”是不一样的.
我们知道,介词单独不作句子成分,必须加上名词词组构成介词短语才能作句子的成分（1.状语、2.定语、3、补语（包括表语）） 我们又知道,有些不及物动词加上一个介词后可以组成一个短语动词,相当于一个及物动词,如：look for his wallet .大家都将look for 看成一个整体,一个意群,而不看作：look for his wallet .其实你非要这么去理解,也未尝不可：为了他的钱包,到处在看.（这种思维,对于记忆look for是“寻找”,也是有益处的）
象汉语字谜问题：什么食品吃得开?---罐头食品（吃得开）.这后面一句,通常的思路是：罐头食品 吃得开.特别的的思路：罐头食品,吃 得开.（当然这是文字游戏,猜字谜常用）
再来看你的问题：sb.is interested in sth.通常的思路是：Sb.is interested in sth.
但English speakers中,可能也有跟我们汉语思维一样的理某人 对某事 感兴趣：Sb.is interested in sth.
你上面的两句中,to与后面的结合较紧,in 与be interested结合较紧.还是习惯自然吧.
至于定语从句,这两个,介词提不提前都有可能,问题不是很大.
2 The boy is interested in such a lovely toy that his parents decide to buy it for him.
若这句要改成such ...that倒装的话 是
Such a lovely toy is the boy interested in that his parents decide to buy it for him.
还是
In such a lovely toy is the boy interested that his parents decide to buy it for him.
感觉这题句是生造的,such ...that...中That从句是结果状语从句.感觉前后句没有这样的逻辑.
有没有,译成汉语就知道.
the boy is so interested in ...that his parents .有可能.（逻辑思维上还是有跳跃）父母决定给他买,其实是因为爱他.是爱他的结果,非也感兴趣的结果.

您好，您说的such 。。。 that引导的结果状语从句可以倒装是对的
但是您要明白是： He was excited to such an degree that he couldn’t sleep last night.中，作状语的是 to such an degree that he couldn’t sleep last night这个结果状语从句，而不单单是
to su...

您好，您说的such 。。。 that引导的结果状语从句可以倒装是对的
但是您要明白是： He was excited to such an degree that he couldn’t sleep last night.中，作状语的是 to such an degree that he couldn’t sleep last night这个结果状语从句，而不单单是
to such an degree。那它倒装的时候也是同理的。
像与degree用法相似的名词，还有extension（前加介词to）、（加介词to、in）range、point（前+介词to）等
至于第二个句子
The boy is interested in such a lovely toy that his parents decide to buy it for him.
在倒装的时候能否把介词in提前呢？
我们一般是不提前的，因为 be interested in 是一个整体，把介词提前的话就破坏了整体，如过您非要，提前的话也不是不可取的。（所以您理解的in+the toy是状语虽牵强，但也是可以这样理解的。）
但是为了保持完整，还是建议您不要提前。（所以也就没有您in+the toy是状语那样的理解了）
关于您对于上述句子成分的问题，我们从英语陈述句（包括肯定句和否定句）的五大句式出发就可以了
1 主语+谓谓+主语补足语（主语补足语就是补充主语的成分）。这个大句式中最为常见的是（主语+系动词+表语，这里系动词作句子谓语动词，它既不属于及物动词，也不属于不及物动词，介于两者之间）
如 He is a student。
2 主语+谓语+宾语（这里的谓语是及物动词，且有被动形式）
如：He likes apples
3 主语+谓语（这里是谓语是不及物动词，没有被动形式。如果动词后要加名词代词等或相应词组，我们要在它们之间加一个介词）
如 He cries 。
He cries for his dead pet
(这里cry为不及物动词，所以第二局中我们加了介词for)
4 主语+谓语+间接宾语+直接宾语（这里的谓语动词是及物动词）
如 he gives his mother a gitf（他给了妈妈一件礼物，其中his mother 为直接宾语，a gift为间接宾语）=He gives a gift to his mother（即把直接宾语提前的话，要在两个宾语之间加个介词，这里我们加了介词to）
5 主语+谓语+宾语+宾语补足语（谓语动词为及物动词）
He makes his mother happy （happy补充宾语，所以我们称之为宾语补足语）
ps 其他陈述句的句式都可以看作这五大句式转化而来的。
我们您仔细看这五大基本句型中，有没有状语、定语、同位语等成分呢？没有吧？
同时也是没有状语从句、定语从句、同位语从句的吧？
所以我们说状语、定语、同位语等成分，在句中是起修饰作用的，如果我们不需要修饰，也就可以省略的。而主语、谓语、宾语、表语、主语补足语、宾语补足语（虽然主补、宾补也是起修饰作用，但是我们不能将之省略）都是句中不可缺少的成分，只有在省略句中才能省略的，一般不省略。
那么您说的这句肯定句属于哪种类型呢？
He was excited to such an degree that he couldn’t sleep last night.首它由两句话组成，一个是主句、一个是从句。
主句是 He was excited 主系表结构，句式一
从句是 to such an degree that he couldn’t sleep last night。
结果状语从句由（such 。。。that）表示excited的程度
而您说的
The boy is interested in such a lovely toy that his parents decide to buy it for him
这个句式同样是 主系表结构的变式，主干就算
The boy is interested in a lovely toy 。such。。。 that。。。同样引导状语从句
