1。of 120 (minerals known) to have been uesd (as genstones), only about 25 are in (common use) in (today jewelry).
请各位大侠分析一下哪里错了

2。The Mississippi riverboat,which (evolved） from simpler （steamship） of the early 1800's ,became the （dominant） form of （passenger transport ）on the Mississippi River.
B 为什么错了，D好像也有问题

3。Icebergs are (usually) white ,blue ,or green,(even though) some are black due to (rock material) incoporated in (them).
为什么B错了，这个句子的结构我不太清楚可以帮我分析一下吗？

4。phenotypic traits,such as size or skin color ,result (to) the interaction (between )an organism's (genetic) makeup and the environment in which the (organism develops).
A错在哪里？请帮我分析一下句子结构

1. jewelry today. just the "order" problem.common use
2.steamship->steamships coz the steamship is countable noun.
3.really don't know, maybe rock materials. reason same as second one.
4.result of......  common use ba.

hope it's right

workman

even though 是即使的意思，但上句中并没有强烈让步关系，窃以为改为but也许通一点

个人认为3中even though 改为though更好。4中A改为in更好。

workman

4中的result应该更from
result from 后面跟的是原因
这句话的意思是大小或皮肤颜色是由机体的基因补偿和环境互相作用引起的

3. 'but' is reasonable.

4. 'result from' is used when result is a verb, while 'result of' is often used when result is a noun.
