问题      Anger and other strong emotions can trigger potentially deadly heart rhythms in certain vulnerable people.
     Previous studies have shown that earthquakes, war or【C1】______ the loss of a World Cup Soccer match can increase【C2】______ of death from a sudden cessation(停止) of heartbeat,【C3】______ the heart stops circulating blood. "It’s【C4】______ been shown in all different ways that when you put a whole【C5】______ under a stressor that sudden death will increase," said Dr. Rachel Lampert, whose study【C6】______ in the Journal of the American College of Cardiology. "Our study starts to look【C7】______ how this really affects the electrical system of the heart," Lampert said.
     She and colleagues studied 62 patients with heart【C8】______ and implantable heart defibrillators (电震发生器) or ICDs that can【C9】______ dangerous heart rhythms or arrhythmias(心律失常) and deliver an electrical shock to restore a normal heart【C10】______ . "These were people we know already had some 【C11】______ to arrhythmia," Lampert said in a telephone interview. Patients in the study took part in an exercise in which they【C12】______ a recent angry episode【C13】______  Lampert’s team did a test called T-Wave Alternans that【C14】______ electrical instability in the heart.
     Lampert said the team specifically asked questions to get people to relive the angry【C15】______ . "We found in the lab setting that yes, anger did increase this electrical instability in these patients," she said. "The people who had the【C16】______ anger-induced electrical instability were 10 times more【C17】______ than everyone else to have an arrhythmia in follow-up,"  she  said. Lampert said the study【C18】______ that anger can be deadly, at least for people who are already vulnerable to this type of electrical disturbance in the heart. "It says yes,【C19】______ really does impact the heart’s electrical system in very【C20】______ ways that can lead to sudden death," she said.  [br] 【C17】
选项 A、possible
B、likely
C、probable
D、liable
答案 B
解析 语义衔接题。本题关键是考查“be____to”的结构，表示“某事发生的可能性或几率”，所以只有B likely符合条件，be likely to指“很有可能……”，故本题答案为B。
