--没有，他在家，因为他感冒严重．

解答 答案：C；
根据语境以及上下文，本题考查的是连词的用法．根据设空处前后句的句意"他在家"和"他感冒严重"，可知后面一句表达是前面一句的原因，所以用连词because引导原因状语从句；故选C．

10．People sometimes say，"It's raining cats and dogs!"when there is a heavy rain．Nobody has ever really seen cats and dogs falling from the sky，but there have been many reports of other strange things"raining"down．In 1956，the people of a town in the USA saw a small blackcloud in the sky．It started to rain from the cloud normally，but only in a small area．The cloud then turned white，and fish started to fall to the ground．Most of them were still alive．
      During a storm in July 1901，in Minneapolis，people heard something falling from the sky that did not sound like rain．When they went outside，they found all types of frogs covering four streets．
     There are other reports of strange"rains"failing from the sky including worms，insects and snakes．
      Can these strange"rains"be explained by science？Scientists usually say that a tornado （龙卷风） has picked up the animals from a river or ocean，carried them for miles，and then dropped them somewhere else．But this does not completely explain all of them．On May 15，1890，in Italy，there was a rain of blood--birds'blood．Scientists said that flying birds must have been torn（撕碎） to pieces by strong winds．But if so，why did only their blood fall from the sky，and not other parts of their bodies？And anyway，there were no strong winds that day!
