寻求《英语世界》老师们的帮助。谢谢先！

一朋友在ESL学英语。在昨天下发的家庭作业里有一道词汇练习题。要求将下列单词分成三组：1. 须用冠词a/an，2. 须用冠词the，3. 不须用冠词。由于是医学词汇，平时使用极少。如何答题，不得而知。故来此寻求帮助。望英语大咖们不吝赐教。谢谢先。

欢迎新同学！

+1:)

Seems a/an,or the ,applies to all,at first glance-;))

看了一下，好像没有需要用The的 :)

1. A cold
2. A flu
3. AIDS
4. A cough
5. hiccups
6. cancer
7. A cut
8. measles
9. A diarrhea
10. An eye infection
11. A dry skin
12. A fever
13. insomnia
14. A headache
15. malaria
16. A stomachache
17. A sore throat
18. A toothache
19. A sunburn

I didn't seem to see any particular one that needs to use "The".

But of course, "The" can be used in certain context in front of the words that has either A or An. 

我在Flu前会用the，但很多人不用。 :)

1. A cold

2. The flu  (But there are some who do not use “the” here.)

3. AIDS

4. A cough

5. hiccups

6. cancer

7. A cut

8. measles

9. diarrhea  (Some would have “A” here.)

10. An eye infection

11. dry skin

12. A fever

13. insomnia

14. A headache

15. malaria

16. A stomachache

17. A sore throat

18. A toothache

19. A sunburn

It seems like "A flu", "The flu", and just "Flu" are all OK :) T

Yes, they just want to confuse people. :)

good point

Do we really need "The" in front of "measles" and "hiccups"?

Honestly that sounds strange to me. :)

也许周一可以找老师问问。有结果一定回馈你。

网上就能找到答案，譬如这些：

"Most cases of hiccups go away on their own without medical treatment."  ----- The Mayo Clinic

"Measles isn't just a little rash. Measles can be dangerous, especially for babies and young children." ----- CDC
