A candlelit dinner works wonders for romance. Now scientists say it could also be good for your heart. Breathing in candle smoke causes beneficial【C1】______in your heart rhythm, they claim. It is thought that tiny salt particles released when the candle burns are【C2】______the effect
The researchers monitored the hearts of 13 men and women as they breathed in air【C3】______into a small chamber. In some【C4】______the air included smoke from candles in a second room. The volunteers didn’t know which type of air they were breathing, but when it included candle smoke, their heart rate variability【C5】______.
Everyone’s heart rate varies【C6】______all the time, beating a little bit faster when we breathe in than when we breathe out This is perfectly healthy and a sign that the brain is【C7】______and able to regulate the heart But this variation【C8】______as we get older and if we【C9】______heart problems. In the study, it was increased by【C10】______candle smoke.
Researcher Christina Isaxon said the concentration of smoke【C11】______during the study was similar to that created by a candlelit dinner. As the volunteers could not see the candles and weren’t told what they were breathing, the effect could not be explained【C12】______by the calming effect of candlelight.
Dr Isaxon believed that tiny particles of the candle smoke could be responsible for the beneficial effects. These particles are【C13】______regulating the heart’s rhythm and in sending messages between cells in the body. More salts are produced when a【C14】______is still. The study did not find any【C15】______health effects of the smoke—【C16】______she admitted she did not ’make a huge effort’ to find any.
Soot, black powder in the smoke, from lit candles has been【C17】______health problems in the past. The American Chemical Society has warned that common wax candles release【C18】______harmful chemicals linked to cancer and other illnessea It recommends using beeswax.
Dr Isaxon used candles made of a natural fat in her study. She recommended using candles that are as natural as possible and avoiding【C19】______and dyes as they may give off【C20】______chemicals when burned.
【C11】
选项
A、condensed
B、dispersed
C、generated
D、polluted
答案
C
解析
基于was similar to的语义,可认为研究者比较了“研究中的烟雾浓度”(the concentration of smoke...during the study)和“烛光晚餐所释放的烟雾浓度”(that created by a candlelit dinner)。C项generated“产生,生成”能对应that后的created一词,代入后指“研究中蜡烛燃烧产生的烟雾的浓度”。
