问题     People faint (晕) when the normal blood supply to the brain is suddenly cut down. This can happen if they are surprised or shocked by sudden news or by something they see. Some people faint if they see others hurt. Some people faint in crowds. Others faint if they are in a room that is hot and with all the windows closed.
   If a person faints while standing, lay him down. If his face is pale, lift his feet. If he is sitting down when he faints, place his head between his knees. Loosen any tight clothing that might keep him from breathing easily. If possible, place cold, wet cloth on his forehead.
选项 A、worded
B、frightened
C、happy
D、worded and frightened
答案 B
解析 此题题干问“人们什么时候可能晕倒”。在原文第1段第2句话指出人们在受到惊吓时会晕倒。因此选项B．frightened是正确答案。
