41．What happened when the author was about to take a photo?

A．Her camera stopped working.

B．A woman blocked her view.

C．Someone asked her to leave.

D．A friend approached from behind.

答案　B

解析　细节理解题。根据第二段中的“...a woman approached from behind，and planted herself right in front of my view.”可知，就在“我”拿出相机的时候，一位女士从后面走过来，正好停在“我”的视线前面，即“我”的视线被挡住(blocked)了，故选B项。
