B)它们通常发生在半夜。 

C)它们造成的破坏会和炸弹一样严重。 

D)它们的巨响可能与爆炸声相混淆。

新闻开头提到，苏格兰发生了罕见的雷雪事件。惊慌失措的当地人以为听到了炸弹的爆炸声，于是报警了。当雷电与暴风雪交织在一起时，就会发生这种现象，有时会产生巨大的响声，让人误以为是爆炸声。由此可知，D为正确答案。新闻中虽提及雷雪产生的巨响威力足以让建筑物晃动，并触发汽车警报，但这并不等于它造成的破坏跟炸弹一样严重，故排除选项C。其余两项新闻中并未提及，可排除。

What did the police do when they received the local residents'phone calls? 警方接到当地居民的电话后做了什么? 

A)他们发公告让民众冷静下来。

B)他们答应阻止施工。

C)他们告诉民众军事演习结束了。

D)他们出发去检查飞机失事现场。

新闻中提到，许多民众在听到巨响后报警，警方发出公告，让人们保持冷静，并向民众保证，这只是雷电现象，而不是什么军事演习，由此可知，选项A为正确答案，同时可排除选项C。其余两项新闻中并未提及，可排除。

What were people advised to do when traveling outside?人们外出时被建议做什么? 

A)注意保暖。

B)注意安全。

C)不要开车。

D)乘坐火车。

新闻最后提到，雷雪天气，气温极低，相关部门警告人们外出时要当心，故选项B为正确答案。选项C和选项D是利用新闻细节信息设置的干扰项，与新闻描述不符，故排除。选项A在新闻中并未提及，可排除。

A rare thundersnow event has taken place in Scotland.And alarmed locals contacted police, thinking they had heard bombs going off. The phenomenon happens when thunder and lightning mix with a heavy snowstorm— sometimes causing loud claps that can be confused with explosions. 

One person described it as a loud boom,similar to a plane crash.Another person was woken up in the middle of the night by what he thought was early construction work starting. The noise was powerful enough to shake buildings and set off car alarms.The police were flooded with many calls from the public.And they sent out a message asking people to remain calm.The police assured everyone that it was just thunder and lightning rather than some military exercise. The weather was the coldest it had been for the season,so people were warned to be careful when traveling outside.In particular,dangerous conditions such as icy roads or wet ground could cause difficulty for drivers. The rail service also announced potential disruptions to trains due to the deep snow.Some roads were also closed because of the severe weather
