Question

I don't know whether you happen to

I don't know whether you happen to have heard ,but I'm going to study in the USA this september.能详细分析一下句子成分吗？谢谢

Answer 1

按照你给出的句子分析:
主(I )+ 谓动(don't know)+ 宾从( whether you happen to have heard) ,but(并列连词, 连接两个分句) I'm going to study in the USA this september.
但前一个分句有错: to have heard有误, 因为hear是"听见"之意,是及物动词,而"听说"可用 hear of,无论是hear还是hear of,后面都必须接宾语. 因此,可修改为:
I don't know whether you happen to have heard of that I'm going to study in the USA this September.(用that 从句来做 to have heard of 的宾语)
句意:我不知道你是否已碰巧听说今年九月我准备去美国读书这件事.
或:I don't know whether you happen to have heard (of) it, but I'm going to study in the USA this September.(it"这件事", 指后面所说的"准备去美国读书"一事.
句意:我不知道你是否已碰巧听见/听说,但今年九月我准备去美国读书了.
