第二题B项是influence

1.A
翻译：她总是使得别人卷入她自己的错误中（即连累别人）.
如果选B,即“她和自己的错误有牵连”,这就是废话了.
2.B
翻译：老师的影响使得我在大学专供科学/理科.
influence指通过行动、榜样等对他人产生潜移默化的影响或作用,注重“影响”的结果.
3.B
翻译：既然你问了,我就会告诉你.
since有“既然”之意,而as翻译成“由于/因为”,不如前者贴切.
4.A
times were hard意思是“那时生活很艰辛”；
而lives是life的复数形式,但是life翻译为“生活”时一般是不可数名词,不会用复数形式lives.所以lives翻译成“生命/生物/活物”,此时不合句意.
