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.
【C15】
选项
A、favorable
B、negative
C、definite
D、impressive
答案
B
解析
上文谈到的study一直围绕“蜡烛燃烧的烟雾对心脏有好处”展开,并没有涉及任何负面因素。下一分句也指出Dr Isaxon并没有花费巨大精力来寻找与之相关的证据。B项negative“消极的,否定的”可满足语篇和逻辑要求。
