Question

有一个长句，帮忙分析一下，谢谢。

"We, the United States, could help the international partners that we could bring into the space station - China, India, South Korea, Brazil - have them join there and began to gradually look at the moon as an international project that the U.S. experience can help the other nations land on the moon, and we'll work with them, but not spend our resources and our big rockets and spacecraft to go to the moon. We've done that. "

have them join there and began to gradually look at the moon as an international project

have的主语是We(或the United States）么？
began的主语是We(或the United States）么？
用began是因为过去开始的么？
介词短语as an international project作什么成份？修饰哪个词？
that the U.S. experience can help the other nations land on the moon, and we'll work with them, but not spend our resources and our big rockets and spacecraft to go to the moon. We've done that.
这整个一块都是修饰project的么？

比较糊涂，请各位指点一下，谢谢。

Answer 1

我觉得HAVE 有IF的味道.If they join and then we can begin to ...
所以join,begin应该是过去式:joined,began.
介词短语as an international project应该是修饰补充look at moon。

that the U.S. experience can help the other nations land on the moon, and we'll work with them, but not spend our resources and our big rockets and spacecraft to go to the moon. We've done that.
是修饰project的，没错。

hav的主语是美国，但是began你确定没打错？这段话看起来不是过去式呢…如果没错，它的主语是china那些国家…as后面接的是一个长的方式状语从句，而usa experienced做project（它是状语从句的主语）的定语从句，再后面的，就是大从句的主干部分啦！……分析时别太盲目
