求助SAT语法。求各路牛人慷慨相助

Because his experience in the naval medical corps had been rewarding, Bob applied to medical school after he was discharged from the navy.
这道题答案是E，但是我对after he was discharged不能理解，之前已经是过去时了，为什么afterXXX还是过去时？？

At the reception were the chattering guests, the three- tiered cake, and the lively music that have become characteristic of many wedding celebrations.
为什么characteristic这个是对的，前面不是有好几项，那不是应该是characteristics吗？不能理解。。。

Because the meteorite Ahnighito, the centerpiece of the Hall of Meteorites, weigh 34 tons, supports for it go through the floor and foundation down to the bedrock beneath the museum.

答案是weigh 34 tons, its supports.
为什么不是weigh 34 tons, supports for it

As a child growing up on a farm, my sister and I visited many county farms, where my parent would exhibit their prize livestock.
为什么答案是growing up on a farm而不是since growing up on a farm…

求指教！！！不胜感激TT

Answer 1

你好。你的问题太容易回答了。
1 after he was discharged==after he had been discharged (如果不强调先后关系，用was比用had been 更容易被接受)
2 记住，这里的 characteristic 是形容词，不是名词。形容词没有复数形式。
3 主语是the meteorite Ahnighito-----它是单数第三人称，所以谓语动词是weighs.
4 growing up on a farm-------指的是“我们”还是正在成长的儿童。

Answer 2

对palmaking 老师的答案两点补充：
1、its supports =the meteorite Ahnighito‘s supports ，指“它的（建筑的）支撑点” ，weighs 是句子的谓语动词，而 its supports 是名词短语，在主句中作主语，缺少its 则 supports 所指不明确；
2、As a child growing up on a farm ，as是介词，意为“作为”，growing up on a farm = who grew up on the farm （作为一个在农场长大的孩子）
请 palmaking 老师见谅并扶正！
