If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't

breathing, you have four minutes before his brain is completely destroyed. Support his neck, tilt(使翘

起) his head back and press his chin (下巴) upwards.This stops the tongue blocking the airway in the

throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth

breathing. Prees his nostrils (鼻孔) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat

twelve times a minute. Keep doing until help arrives.

To bring a child back to life, keep your lips around his mouth and nose and gently blow into his

mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your

efforts, he starts tuming a blue-grey colour, and you can feel no pulse (脉搏) , then pressing is the last

chance of saving his life.

With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too

hard or you may break a rib(肋骨). Check how effective you are seeing if his colour improves or his

pulse becomes independent to your chest pressing. If this happens, stopthe pressing. Otherwise continue

until rescue amves.

1. This passage is mainly about .

A. how to save people out of the water

B. how to give first aid to people who are drowning

C. how to do mouth-to-mouth breathing

D. how to save a child from a nver

2. Once you get a drowning man out of the water, if he isn't breathing, you must first .

A. get him breathing again

B. take him to the nearest hospital as soon as possible

C. find someone to help you

D. call the First Aid Centre

3. In the last paragraph, the underlined word "rescue" means .

A. breath

B. help

C. doctor

D. pulse

4. If the drowning boy has no pulse, .

A. pressing his chin upwards is enough to get him breathing

B. blowing air into his mouth is sure to save his life

D. pressing is the last chance of saving his life

阅读以下文字，完成以下问题。
据美国《华盛顿邮报》日前报道，在美国明尼苏达州，一些猪的血管中流淌着人类的血液；在美国内华达州，一些绵羊拥有着人类的肝脏；在美国加利福尼亚州，一些拥有人类脑细胞的老鼠从它们的笼子中向外界窥望……
据报道，生物学家们将这些带有人类血液或细胞的动物称做“混血赫迈拉”(hybrid-schimeras)，赫迈拉是希腊传说中拥有狮头、羊身、蛇尾的吐火怪兽，在过去数年中，美国科学家将人类的干细胞加入到了许多动物的发展胚胎中，秘密炮制出了许多实验性的“混血赫迈拉”产品。
据报道，在一个正在进行的实验中，美国明尼苏达州罗切斯特马约医院的杰弗里•普拉特医生通过将人血干细胞注入进猪的胚胎，已经建立了一些“人猪赫迈拉”，这些猪体内的血管中既流着猪的血，也流着人的血。普拉特称，一些人血细胞和猪血细胞已经自然发生结合，这对医学界是一项重要的发现。因为科学家一直在考虑将一些猪器官移植到病人身上，但同时又不知道猪身上的病毒会不会潜入人体内，对人类形成危害。如今科学家发现这一担心是真实的，因为猪体内的病毒可以通过人猪细胞的融合获得感染人类的途径。
在另外一些实验中，以美国内华达大学的伊斯梅尔•赞贾尼为首的科学家已经将人类干细胞添加到了绵羊的胚胎中，炮制出了一些“人羊赫迈拉”，如今这些“混血羊”体内的肝脏——80%的成分都属于人类的肝脏。还有一些实验中，科学家将人类的脑细胞注进老鼠的头盖骨内，这些拥有人类脑细胞的老鼠从它们的笼子中向外窥望时，天知道它们的脑海中在想些什么。
在过去数年中，美国科学家将人类的干细胞加入到了许多动物的发展胚胎中，秘密炮制出了许多实验性的“混血赫迈拉”产品。
然而，当科学家试图将整个人体器官放在动物的体内生长，“混血赫迈拉”实验就成了二个非常敏感的话题。当科学家试图将人类脑细胞也注入动物的头盖骨内时，这一话题将变得尤其敏感——被用于实验的动物是否会变得像人类一样聪明
目前，“混血赫迈拉”实验已经在美国研究界引发了巨大的[ ]争议，在更严格的规则制定出来前，科学研究到底会走到哪一步
如今的美国科学家和威尔士科幻小说《莫鲁博士岛》上炮制半人半兽怪物的医学狂人有什么本质区别

对“如今科学家发现这‘担心是真实的”理解有误的一项是( )。

A．科学家担心将猪器官移植到病人身上时也会把猪身上的病毒带进入体

B．“人猪赫迈拉”实验指出了医治某些人类疾病的奇妙方法

C．在医学上，能否将猪器官移植到病人身上的实验需要慎重考虑

D．猪体内的病毒可以通过人猪细胞的融合获得感染人类的途径
