should have thought

I should have thought 有时具有这样的含义: 我原来以为如何如何, 但我错了。但是有时也表示惊讶或批评:

1. 20 degrees? I should have thought it was colder than that if you hadn't told me. (LDCE)

20度？如果你没有告诉我的话，我还以为气温比这低呢。

2. I should have thought he could have washed his hands, at least. (PEU) 我本来以为他至少能把自己的手洗洗。

你提问的句子似可译为：

她才35岁吗？我原来以为她的年纪比这大多了。

should not + 完成体不定式表示“本不应该做某事，而实际上却做了”的意思：

1. You should not have gone up to college so soon. (But you did) 你本不应该这么早就上大学的。

2. They shouldn't have come. (Wilde) 他们本不应该来。

ought to 也可以用于此种结构,但没有 should 用得普遍(参见 ought to have done)。请做下面的英语试题:

1. “When should I get my tickets?” “You ____ your tickets last month.”

A. should get B. had got C. should have gotten D. ought to get

2. "Did Bob do his homework?" "No, but he ____.

3. "You ought to have gone to see your uncle yesterday." "Yes, I ____.
