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.
【C20】
选项
A、enormous
B、fantastic
C、fearful
D、dangerous
答案
D
解析
as表原因,说明需要避免在蜡烛中使用染料(dye)的原因:燃烧时释放出……化学物质。通常,只有释放出的化学物质对人体有害,才需要人们去尽力避免,故D项dangerous“危险的”正确。A项enormous“巨大的”可形容化学物质在数量上的特征,但上文并没有与之相关的语义环境。如果染料能产生让人愉悦的化学物质,Dr Isaxon就不会建议避免把它们加入蜡烛中,故排除B项fantastic“奇妙的”。染料或制造蜡烛时所添加的化学物质从常理上来说不会让人感到恐惧,因此C项fearful“吓人的,可怕的”不正确。
