用an,因为在这里issue的音标是['iju:],开头是元音音素[i]。
拓展：
不定冠词a , an 的用法：
1、a用于辅音前；an用于元音前.一般说来,元音字母发元音,辅音字母发辅音。
2、请注意以下3点：
1）.拼写以辅音字母开头读音却以元音开头的单词hour,honest,honor等单词的拼写虽然以辅音字母h开头,但其读音却以元音开头,因此,前面要用an.如：An hour ago,an honest man accepted an honorable task.(一小时前,一位诚实的人接受了一项光荣的任务.)
2）.拼写以元音字母开头读音却以辅音开头的单词useful,university,usual,European,united,one-eyed,one-way等单词的拼写虽然以元音字母开头,但其读音却以辅音开头,因此,前面要用a，如：In a university,a European and a one-eyed man walk along a one-way road with a usual tool.This is a usual thing.在一所大学里,有一个欧洲人和一个独眼龙拿着有用的工具沿着一条单行道行走,这是件平常的事。
3）.英文字母前用a还是用an的问题在26个英文字母中,a,e,i,o,f,h,l,m,n,r,s,x等12个字母的读音是以元音开头的,其余字母则是以辅音开头的.如：
There is an "h", an" o",a "u ",and an "r " in the word "hour ".
在单词“hour”中有一个“h',一个”o",一个“u",和一个”r"。
do是可以浅显的理解为做，你翻译成中文do a bath，就是做一个淋浴。这根本讲不通啊。有的词语类似于bath breakfast这样的，只能用have，have a bath（淋浴） ,have breakfast（吃早餐），类似于是固定搭配。而do homework，做家庭作业就通顺了。当你要用do的时候，你不妨翻译成中文看看，do a _ ，你翻译成做_，看是否通顺。不知道你明白没有
