⑴ 英语语法结构
主语Marilla
谓语was pleased
状语to hear that 从句
to hear...是非谓语动词语法点中不定式表示前面形容词(情绪词)的原因
that是hear的宾语从句
⑵ 能帮我解释一个英语语法结构吗
单独看你的提问，无法解释，它所在的原句是：
insignificant as those changes may seem, they are the signs of the improved economic condition in China.
这是as引导的“让步”状语从句（尽管），是倒装结构。
关于as 引导的让步关系的从句非常有用，下面具体介绍：
As引导让步状语从句倒装的用法
一、名词 + as / though + 主语 + 动词
King as he was，he was unhappy. 他虽是国王，但他并不幸福。
Child as he is，he knows to help other. 他虽是个孩子，却知道帮助别人。
【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语。另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。比较：
Boy as ［though］ he is， he likes to play with girls.=Though he is a boy，he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩。
Strong man as ［though］ he is，General Botha has been severely put to the test ring the past few weeks.= Though he is a strong man， General Botha has been severely put to the test ring the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验。
二、形容词 + as / though + 主语 + 动词
Successful as he is，he is not proud. 他虽然成功，但不骄傲。
Improbable as it seems，it’s true. 虽然看起来不太可能，但却是真的。
Stupid as it sounds，I was so in love with her that I believed her. 尽管听起来很愚蠢，我是如此爱她竟然相信了她的话。
Patient as he was，he didn’t like waiting that long. 他虽说有耐心，也不愿等这么长。
Beautiful though the necklace was，we thought it was over-priced. 那条项链虽然很漂亮，我们认为价钱太高。
【说明】其中的动词也通常为连系动词，也就是说位于句首的形容词是其后连系动词的表语。
三、副词 + as / though + 主语 + 动词
Much as I like Paris，I couldn’t live there. 尽管我喜欢巴黎，但我不能住在那里。
Hard though they tried，they couldn’t make her change her mind. 尽管他们做了很大努力，却没法让她改变主意。
Fast as you read， you can’t finish the book in two days. 尽管你读得很快，你总不能在两天之内就读完这本书。
He was unable to make much progress，hard as he tried. 尽管他做了努力，却未能取得很大进步。
【说明】有的词典将 much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词。再如：
Much as I admire him as a writer，I do not like him as a man. 他作为一名作家我很佩服他，但我却不喜欢他这个人。
Much as I like you，I couldn’t live with you. 我尽管很喜欢你，却不能和你在一起生活。
四、动词原形 + as / though + 主语 + 动词
Object as you may，I’ll go.纵使你反对，我也要去。
Try as he might，he couldn’t solve the problem. 尽管他想方设法，却未解决这个问题。
Search as they would，they would find nobody in the house. 无论怎样搜查，他们在房子里仍然没有找到一个人。
Dislike him as we may，we must acknowledge his greatness. 尽管我们不喜欢他，但必须承认他的伟大。
Lose money as I did，we got a lot of experience. 钱虽然丢了，我们却得到了许多经验。
Fail in the election as he did，he became famous for his fiery speech against slavery. 尽管落选了，但他却以其反对奴隶制的激烈演说而出了名。
【说明】主语后的动词通常为 may，might，would，did 等情态动词或助动词(若表示情态意义，则选用情态动词；若陈述事实，则用 did，do 等助动词)。
五、分词 + as / though + 主语 + 动词
Raining hard as it is， I’m going out for a walk. 虽然正在下着大雨，我还是要出去散步。
Surrounded as we were by the enemy，we managed to march forward. 虽然我们被敌人包围着，但我们还是设法前进了。
Munching the apple as he was，he had got an eye for all John’s movements. 他尽管在一个劲地嚼着苹果，但仍警惕着约翰的一举一动。
【三条补充说明】
1.这类倒装的让步状语从句可用 as， though 来引导，不能用 although 来引导；但是，未倒装的让步状语从句却可用 though， although 来引导，而不能用 as 来引导。也就是说， although 引导让步状语从句时不能倒装，as 引导让步状语从句时必须倒装，而 though 引导让步状语从句时可以倒装也可以不倒装。如：
虽然很晚了，但我们还是继续工作。
正：Late as ［though］ it was，we still went on working.
正：Though it was late，we still went on working.
误：Late although it was，we still went on working .
误：As it was late，we still went on working.
2. 上面提到的倒装结构有时也可用来表示原因，区别的办法主要看句子的内容：让步从句的内容大多数与主句在意义上相反，而原因从句则与主句之间有因果关系。比较：
Tired as he was，he sat up late studying at night. 昨晚他虽然很疲倦了，但还是学习到很晚才睡。(表让步)
Tired as he was，he went to bed early. 因为很累，所以他睡得很早。(表原因)
Young as he was，he was equal to the task. 他虽年轻，却能胜任这项工作。(表让步)
Young as he was，he was not equal to the task. 他因为年轻，所以不能胜任这项工作。(表原因)
3. 在美国英语中，人们通常用 as...as 引导让步状语从句。如：
Cold as it was， we went out.=As cold as it was， we went out. 尽管天气冷，我们还是出去了。
Successful as he is， he is not proud.=As successful as he is， he is not proud. 他虽成功了，但不骄傲。
⑶ 英语语法结构
这句话的语法结构是一般疑问句中套了一个宾语从句。Do是助动词，you是主语，think 是动词，think 后面省略了that ，aliens are real是宾语从句。
⑷ 英语语法结构说明
首先它不是从句，因为凡是从句必须有主谓语，此处既无主语又无谓语。

5. 主语+及物动词+宾语+宾语补足语（主谓+复合宾语结构）

（1）接名词作宾补的动词：find, think, elect, name, call, appoint, consider, make, leave等。

（4）接副词、介词短语等作宾补的动词有leave, put等。
如：The police put the thief in prison. 警察把这小偷关进了监狱。
（5）有些动词后常用it作形式宾语，而将真正的宾语放到宾语补足语的后面，这是英语中常用的句型,即"主语+谓语+it+宾补+真正的宾语"。常见动词有think, find, consider等。
如：I consider it possible to work out the problem in another way. 我认为有可能用另一种方法解题。

⑼ 关于英语语法结构的分析
distribution: 在商业中称为销售系统。
distribution costs：销售费用
more than justified: 不对等，不合适，不合算
bring about 造成；带来，引起。
Distribution costs are typically high but are more than justified by the increased sales potential that is brought about by this wide and extensive distribution.
销售费用一般会比较高，但是它高过了由这个扩张的销售系统带来的销售额的可能的增长，就不合算了。
把这个句子分成两部分。Distribution costs are typically high but are more than justified 销售费用一般会比较高，但是（现在的情况下,它是）不合算了。
by the increased sales potential that is brought about by this wide and extensive distribution. 销售费用比较销售额的可能的增长：by the increased sales potential . 而the increased sales potential 是由从句 that is brought about by this wide and extensive distribution 来修饰（解释）.
