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.
【C14】
选项
A、flame
B、room
C、candle
D、volunteer
答案
A
解析
首段最后一句话表明句中的salts指的是蜡烛燃烧时释放的“微小盐颗粒”。既然这些盐颗粒是蜡烛燃烧时释放出的,就应推断释放的盐颗粒的数量受蜡烛燃烧情况的影响。四个选项中只有A项flame“火焰”与蜡烛燃烧相关。B项room“房间”和D项volunteer“志愿者”与蜡烛燃烧没有关联。烛光晚餐中的蜡烛以及其他被点燃的蜡烛都不会被随意挪动。因此不应把蜡烛自身的“静止”作为考察盐颗粒是否增多的条件。C项代入后体现的逻辑不符合常理。
