我是师范学校毕业的,
首先这句话的意思是：
因为海伦生气了,我们最好（应该）离她远点,让她静一静.
since引导的句子通常是时间状语从句,主句用一般现在时,从句用现在完成时.
但在这句句子中,since作“由于,因为”理解,不引导什么从句,所以做题时根据句意来做即可.
答案选B
A选项里,leaving改为leave就对了,had better do sth.用动词原形
C选项在本句中涉及到了最佳选项问题,理论上来讲,C也是对的,但因为有B选项的存在,C与B比较,B更加符合句意.
D选项也没这种写法,要么had better do,要么would rather do.

选B 尽然海伦饿了，我们应该让她留下来

选B，这里的since是表示原因，引导原因状语从句，翻译成由于，因为。。。
本句翻译：因为helen很生气，所以我应该让她静一静。
A。leaving应该改成leave
C。might的意思在这里讲不通
D。had rather是宁愿的意思，在这里也讲不通。

B 这题与时态无关 这儿since是连词 既然

C might as well 不如 不妨
这里since是因为的意思 根据句意 因为海伦很生气，我们不如让她自己呆会儿吧
解释为自从的意思时，一般用现在完成时
望采纳,有问题再联系 O(∩_∩)O~

B,连词，与时态无关

Since 用在什么时态中 since用于什么时态 since用于什么时态 句子中有since或for用什么时态,结构是什么? 如果主句是现在完成时态,那么回答它的句子如果有since,那么since后接什么时态,为什么 分析这个英语句子的时态和句意!it is／was 3 years since he came here.since不一定和完成时连用吗?用is或was有什么区别 为什么since不能用做that?
