1. 可以的。比如在和朋友说你的电话号码的时候。另外,对于两个或三个的情况,也常常说“double",or "triple"的。2。哈哈, 回答1的时候没有看到。在交谈中,6501999会说成 six five zero one and triple nine. 但是如果你说。。。and three nine 也是可以的。对于999 8888, 有人会说 triple 9 followed by hour nights. 口语里的格式很随便。只要不造成误会就好。3. Does you cellphone still have power?4. My cellphone still have a lot of power no, my cellphone does not have too much power. 有时也说: my cellphone does not have many bars now 等5. 你的句子不常见,但是也不会有误会。 常见的是:my cellphone"s battery is out.
