Question

谁能帮我解决几个英语方面的问题?

1.Today being sunny makes us happy.这个句子里主、系、表和逻辑主语分别是什么。
2.His aim is everybody having a good time.这里的have为什么用动名词?
3.I am astonished at Mary suddenly becoming rich,可以用Mary‘s吗？
4.这个句子是对的吗，Helen用不用改成Helen’s，为什么：Helen getting married last week was a great event in the town.
5.It looked like rain this morning,but it has turned out to be a fine day.这个句子里为什么要加to be？
问题有点多，希望高手耐心指点，谢谢！

1，Today being sunny做主语，makes谓语，us宾语，happy宾语补足语。没有逻辑主语（这个我不太肯定）。如果说有那就是today做Today being sunny的逻辑主语。
2.is是谓语，一个句子里不能有两个谓语，everybody having a good time前没有引导词，所以不是从句，所以不能有谓语，所以have不能用原型，用动名词。可改为His aim is that everybody have a good time。
3.可以。只能用Mary‘s。astonished at接名词，Mary suddenly becoming rich不是名词，Mary‘s才算是。可以改成I am astonished at the fact that Mary suddenly became rich。同位语从句。
4.我觉得不对，只能用Helen’s。当动名词有自己的逻辑主语时，常可以在前面加上一个名词或代词的所有格，构成动名词的复合结构(——这时，名词或代词的所有格做动名词的逻辑主语)。动名词的复合结构也可以在句中作主语。例如：Their coming to help was a great encouragement to us.
5.turned out to be词组，结果是，不可以拆开的。
貌似你对动名词做句子成分不太了解。可以看看语法书。

1.Today being sunny makes us happy.这个句子里主语是动名词短语being sunny，谓语是makes，us
是宾语，happy是宾语us的补足语。
2.His aim is everybody having a good time.这里的everybody having a good time是动名词的复合结构，
用作表语。everybody's having a good time
3.I am astonished at Mary suddenly becoming rich,可以用Mary‘s.
4.这个句子是对的吗，Helen用不用改成Helen’s，为什么：Helen getting married last week was a great
event in the town.=Helen's getting married last week was a great event in the town.这是动名词的复合结
构做句子的主语。
5.It looked like rain this morning,but it has turned out to be a fine day.这个句子里为什么要加to be？
因为turn out后面要接动词不定式。turn out to do / be是固定短语，
