“Tomorrow I want you to give us a talk, Jim. Please give us a short talk. Nothing difficult!” “A talk? What subject should I talk about?”(《初中英语教科书》第三册，人教社，p.2) 该书在《课文注释》(p.97)中说：
“should 作为情态动词和疑问词连用时，常常表示意外、惊奇、不能理解等，有‘竟会’的意思。又如：
How should I know? 我怎么知道？
‘Give me that photo.’ ‘Why should I?’ ‘把那张照片给我。’ ‘为什么(要)给你?’”
请问在我所提问的句子里 should 是表示“意外、惊奇、不能理解”吗？
虽然 should 与疑问词 (why, how 等) 连用有时含有“惊奇、意外”等含义, 但是不能认为 should 凡与疑问词连用便具有“惊奇、意外”等含义。例如, 你所提问的句子里的 should 就没有“惊奇、意外”的含义, 而仅仅是表示“应该”“应当”, 相当于 ought to。请看下面的实例:
-
Who should we invite? /Who ought we to invite? 我们应当邀请谁呢？
-
The housekeeper considered how she should answer. 管家在考虑她应该如何回答。
[试译]……讲话？我应当讲什么题目呢？
