1 even if：即使；虽然
even though1.
即使,纵然,尽管,虽然,甚至2.
即使,纵然
两者意思相近,但even if经常用于将来时这种条件是只基于一种可能,even though 可以用于多种动词形态,=although.
我觉得举例比较简单：
Even if my ex-girlfriend is at the party, I’m going to go.
I won’t work overtime this weekend even if my boss asks me to.
Even if my company offers me a promotion, I won’t take it.
Even though I was invited to the party, I didn’t go.
I will work overtime this weekend even though I don’t want to.
Even though my friend isn’t good at singing, he always sings a lot at karaoke.
下面的是一位著名英语老师的解释：
The grammatical expression “even though” can be used with various verb tenses and has the same meaning as the word “although”.
However, “even if” is usually used to talk about what you will do at a future time despite something which might go against your plan.
Please note that “even if” is usually used with a future situation and that the situation on which the decision is based is only a possiblity.
2根据句子意思
天将要下雨了,因为气压降低了（for）
天将要下雨了,所以气压降低了（so）如果换成现在时或过去时,那么这个才讲得通

（1）even if 与 even though
这两个词组大致意思相当，但强调的侧重有所不同。
even if与even though的区别：
even if一般引导的是把握不大或假设的事情,
even though引出的是事实。
如：Even if we achieve great success in our work, we should not ...

（1）even if 与 even though
这两个词组大致意思相当，但强调的侧重有所不同。
even if与even though的区别：
even if一般引导的是把握不大或假设的事情,
even though引出的是事实。
如：Even if we achieve great success in our work, we should not be proud.
即使我们在工作中取得了巨大成绩，也不应该自满。
Even though he was late, he was not criticized by the teacher．
虽然他晚了, 可他并没有受到老师的批评。
Even though he knows it, he'll not let out the secret.
（他知道这个秘密）.
Even if he knows it, he'll not let out the secret.
（不确定他是否知道这个秘密）.
though 常表示一些已经确定的消息，
而if由它本身所带的“如果”的含义，表示了一种对假设信息的不确定。
（2）是will，未发生的事。所以不能用so

收起

共同点是都表示尽管，纵使，区别是A后面是假设性的，而C后是真实的。而这个句子里他身体还没恢复健康。所以选A
天要下雨了，因为气压计正在下降。
所以选FOR表示原因,选SO是所以的意思。欢迎追问。满意请采纳。

1.even if一般引导假设性从句，可以加虚拟语气，even though引导真实性从句，“尽管，虽然”。2.当as引导句子的时候，as是要充当句子中的某部分的，题中后半句是一个完整的句子，所以不能用as，只能用for，相当于把后面的句子当做一个词！
