</p>This prevents fraudsters recording the beeps.noting the card details and then playing back the audible ID when they key in the details later.But this earlier technology cannot prevent fraudulent use of stolen cards.The new one can.8 ]' ^- ^. x! g2 {
The new voice card also identifies itself by-its ID squawk、but it will not do this until it has verified the legitimate user’s spoken password.Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner’s voice with a high degree of accuracy.
" V9 n/ l5 r- ?( j4 _% q2 `The challenge for Beepcard has been to develop voice—recognition and audio circuitry that can be powered by a mini battery embedded in a credit card.To maximize battery life,the electronics are only switched on when the card is being used.Pressing a button on the card’s surface prompts it to utter “Say your password” in female voice.If the voice-recognition software proves that the password is authentic, it sends its ID squawk which the server then identifies,allowing the transaction to proceed.% r3 z: T* s6 P. b! {% C

5 K. o# J: A7 ~, B" O3 p1.B 第一段虽然提到了感冒常发生于冬天,但紧接下去说得很清楚:受凉并不导致感冒,所以A不是正确答案。文章第四段第一句说得明白:感冒通常是与感冒的人身体直接接触而传染的,而不是由打喷嚏或咳嗽传染的,所以C项也不是正确答案。至于D更是错误。答案B与第一段第三句的意义相吻合,因此是正确答案。
/ m( K2 z# |+ s. ^ X% g: B2.A 第五段的第一句话“Hygiene is your best defense”意思是“卫生是你的最佳防御”,与A项相吻合,因此A项是正确答案。同一段中提到的用消毒肥皂洗手,虽然也是保持卫生的手段之一,但仅是一个具体措施,不是全部措施,所以B项不是正确答案。C项提到的服阿司匹林是治感冒的手段之一,而非预防手段(况且没有说到“一天服两片”!)D项提到的多喝水在文中也指治疗手段,所以c和D都不是正确答案。' U: ~( `6 }8 z7 d
3.B 第二段中提到儿童平均一年得八次感冒,这是一个统计数据而不是儿童得感冒的原因;文中并没有说“儿童从不洗手”;文中也没有说“儿童不喜欢吃柠檬”;所以A、C、D都不对。B项与第二段最后一句意思一样,是正确答案。
3 X- K' A* g+ e$ y' t0 I4.C 第三段提到有150种感冒病毒,而人们绝不会被同一种病毒侵害两次,因为得了一次感冒后对相应的病毒就获得了免疫力,所以只有C项才符合第三段的内容。

7 s0 }9 r+ @# k0 n8 f& l; O8 t5.D 本题谈的是文中提及的感冒症状。文中并没有提到得了感冒就胃疼,实际上文中根本就没有“stomachache”这个词或相关的字眼,所以D项是正确答案。 |
