You've probably heard of the list of factors that put you at risk for heart disease:smoking,poor diet,lack of(27)Jand so on.But did you know that the health of your gums(牙龈)may also affect your chance of(28)Cheart disease?
More than 120studies have investigated the(29)Flink between gum disease and heart disease.Most of them say that gum disease is a risk factor for heart disease and other diseases that affect blood vessels.This means that people with gum disease often develop heart disease but that gum disease doesn't(30)Dcause heart disease.
Doctors and scientists have proposed a number of possible reasons for this connection.One common factor is inflammation(发炎),which occurs when the body senses a(31)Aand sends white blood cells to attack it.This leads to painful swelling(肿胀),which is the main symptom of gum disease.White inflammation hasn't been shown to cause heart disease,it often accompanies it.And as it turns out,the same types of bacteria often lead to inflammation in both diseases.
It's also possible that the(32)Hhas less to do with biology than with an individual's habits.Perhaps people who take good care of their teeth make other healthy choices that prevent heart disease.
So what does this mean for your health?Since the role of gum disease in causing heart disease isn't(33)B,don't take it for granted that taking care of your teeth will protect your heart.Certainly,brushing and cleaning are not replacement for exercise and a(34)Kdiet.But keeping your mouth healthy and avoiding gum disease are still good goals to go after.They'll spare you pain and high dental bills and keep your bright smile complete.
This research does mean that if you have gum disease,you should get your heart(35)Ethis is especially true if you are at risk of heart disease for other reason,such as smoking.
Who would have thought that your mouth and your heart would be connected?The body is a complex and mysterious thing,so do all you can to(36)Iit.
分析 本文主要讲述了牙龈健康可能会导致心脏病,但是据调查,患有牙龈疾病的人常患心脏病,但牙龈疾病并不一定会引起心脏病.当前牙龈疾病在心脏病中的作用还不确定,因此建议如果你患了牙龈疾病,你最好也进行心脏的检查.文章告诉我们身体是一个复杂而神秘的东西,所以尽你所能去保护它.
解答 27-36 J C F D A H B K E I
27.J.考查名词.根据前一句"You've probably heard of the list of factors that put you at risk for heart disease"可知,冒号后面的内容写的是一些导致心脏病风险的因素,"lack of"意为:缺乏.结合选项,根据常识,缺乏锻炼也可能会导致心脏病.故选J.
28.C.考查动词.根据前文可知,第一段列举了一些导致心脏病风险的因素,根据本句句意可推测,牙龈的健康也可能会导致心脏病,结合选项,"developing heart disease"意为:患心脏病.句意:但是你知道牙龈的健康也会影响你患心脏病的几率吗?故选C.
29.F.考查形容词.根据句意,结合选项,"potential"意为潜在的.文章第一段也提到牙龈的健康可能会导致心脏病,存在一种可能关系,故其联系也是潜在的.句意:超过120项研究调查了牙龈疾病和心脏病之间的潜在联系.故选F.
30.D.考查形容词.根据句意,"but"连接两个句子,故有转折之意,故后一句意为牙龈疾病并不一定会引起心脏病.句意:这意味着患有牙龈疾病的人常患心脏病,但牙龈疾病并不一定会引起心脏病."doesn't necessarily"意为:不一定.故选D.
31.A.考查名词.根据"sends white blood cells to attack it"可知,机体收到某种信息后会发送白细胞攻击它,由医学常识可知,机体收到病原体的威胁时会发出信号释放白细胞.句意:一个常见的因素是炎症,当机体感觉到威胁并发送白血球攻击时,就会发生炎症.故选A.
32.H.考查名词.根据后一句"Perhaps people who take good care of their teeth make other healthy choices that prevent heart disease."可知,也许照顾好牙齿的人会做出其他健康的选择来预防心脏病.可见,牙龈疾病可能与人的习惯有关系."connection"意为:联系,关系.故选H.
33.B.考查形容词.根据后一句"don't take it for granted that taking care of your teeth will protect your heart."可知,不要认为保护牙齿就可以保护心脏,由此推测,牙龈与心脏之间的关系还处于不确定的状态.句意:由于牙龈疾病在心脏病中的作用还不确定,所以不要想当然地认为保护牙齿会保护你的心脏."isn't certain"意为:不确定.故选B.
34.K.考查形容词."and"连接两个意义相似的句子或单词短语."exercise"意为:锻炼.是有益于保护心脏的,故and后应该是健康饮食.句意:当然,刷牙和清洁不是锻炼和健康饮食的替代品.故选K.
35.E.考查动词,根据前文可知,牙龈的健康也可能会导致心脏病,但是牙龈疾病在心脏病中的作用还不确定,因此可知,如果你有牙龈疾病,你应该去进行心脏检查."checked"意为:检查.故选E.
36.I.考查动词.根据常识,机体器官很复杂,因此我们要保护它."preserve"意为:保护.句意:身体是一个复杂而神秘的东西,所以尽你所能去保护它.故选I.
