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 illnesses. 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.
【C2】
选项
A、behind
B、to
C、among
D、with
答案
A
解析
上文谈到蜡烛燃烧的烟雾有利于心率,空格句试着解释原因。空格后the effect是上句谈到的烟雾对心率的影响,A项behind与之搭配指“这一效果背后的原因”。B项to the effect“大意是”,语义不符合要求。C项among代入后表明主语所指代的内容是烛光晚餐对身体“影响”的一部分,逻辑不符合要求。D项with代入后指“与影响一起”,不通顺。
