I called on Mrs. Strickland before I left. I had not seen her for some time, and I noticed changes in her; it was not only that she was older, thinner, and more lined; I think her character had altered. She had made a success of her business, and now had an office in Chancery Lane; she did little typing herself, but spent her time correcting the work of the four girls she employed. She had had the idea of giving it a certain daintiness, and she made much use of blue and red inks; she bound the copy in coarse paper, that looked vaguely like watered silk, in various pale colours; and she had acquired a reputation for neatness and accuracy. She was making money. But she could not get over the idea that to earn her living was somewhat undignified, and she was inclined to remind you that she was a lady by birth. She could not help bringing into her conversation the names of people she knew which would satisfy you that she had not sunk in the social scale. She was a little ashamed of her courage and business capacity, but delighted that she was going to dine the next night with a K.C. who lived in South Kensington. She was pleased to be able to tell you that her son was at Cambridge, and it was with a little laugh that she spoke of the rush of dances to which her daughter, just out, was invited. I suppose I said a very stupid thing.

"Is she going into your business?" I asked.

"Oh no; I wouldn't let her do that," Mrs. Strickland answered. "She's so pretty. I'm sure she'll marry well."

"I should have thought it would be a help to you."

"Several people have suggested that she should go on the stage, but of course I couldn't consent to that, I know all the chief dramatists, and I could get her a part to-morrow, but I shouldn't like her to mix with all sorts of people."

I was a little chilled by Mrs. Strickland's exclusiveness.

"Do you ever hear of your husband?"

"No; I haven't heard a word. He may be dead for all I know."

"I may run across him in Paris. Would you like me to let you know about him?"

She hesitated a minute.

麻烦老师详解一下这里"I should have thought it would be a help to you."表达的含义，是对过去的虚拟，还是对过去的推测呢？主要是如何理解？

谢谢老师！
