托福阅读背景知识之虚拟现实与化学疗法

Grapefruit， orange and apple juices can harm the body's ability to absorb certain medications and make the drugs less effective， said a Canadian study released last week in the United States.

上周在美国发表的一篇加拿大研究报告学习啦在线学习网指出，柚子汁、橙汁、苹果汁会损害身体吸收某些药物的功能，从而降低药物的功效。

The research showed that these juices can decrease the effectiveness of certain drugs used to treat heart disease， cancer， organ-transplant rejection and infection， "potentially wiping out their beneficial effects，" it said.

学习啦在线学习网此研究表明，这些果汁会降低某些治疗心脏病、癌症、以及器官移植排斥和传染的药物的效力，并潜在抵消药物有益的作用。

David Bailey， a professor of clinical pharmacology with the University of Western Ontario and leader of the study， was the first researcher to identify grapefruit juice's potential to increase the absorption of certain drugs two decades ago， possibly turning some doses toxic.

学习啦在线学习网这次研究的负责人，西安大略大学的临床药理学专家大卫·贝利，已于两十年前首次证实了柚子汁可能会增加某种药物的吸收，并可能形成一些有毒的物质。

The new findings came as part of his continuing research on the subject， and were presented at the 236th annual meeting of the American Chemical Society on Philadelphia， Pennsylvania.

学习啦在线学习网这个新的发现作为他在这个专题持续研究的一部分，在宾夕法尼亚州费城的美国化学协会第236届的年会上发表。

"Recently， we discovered that grapefruit and these other fruit juices substantially decrease the oral absorption of certain drugs undergoing intestinal uptake transport，" AFP quoted Bailey as saying.

“最近，我们发现柚子汁和其他果汁大大地减少了某些口服药物在肠道内摄入转移的量。”支持贝利的AFP如是说。

学习啦在线学习网"The concern is loss of benefit of medications essential for the treatment of serious medical conditions."

“真正的担忧是药物失去了其对于治疗某些严重病情的本质疗效。”

学习啦在线学习网Healthy volunteers took fexofenadine， an antihistamine used to fight allergies， along with either a glass of grapefruit juice， a glass of water with naringin (which gives the bitter taste to grapefruit juice)， or plain water.

学习啦在线学习网健康的志愿者服用一种治疗过敏症的抗组织胺药fexofenadine，并分别用一杯柚子汁、泡柚皮甙的水(此种水会使柚子汁的味道更苦)和白开水送服。

Those who drank the grapefruit juice absorbed only half the amount of fexofenadine， compared to those who drank plain water.

学习啦在线学习网那些用柚子汁送服的对fexofenadine的吸收量仅为那些用纯水送服的人的一半。

学习啦在线学习网Researchers said the water with naringin served to block "a key drug uptake transporter， called OATP1A2， involved in shuttling drugs from the small intestine to the bloodstream."

学习啦在线学习网研究者说，喝了泡有柚皮甙的水会阻碍一种叫做OATP1A2的关键的药物输送物质，该物质可以帮助药物从小肠转移至血液中。

学习啦在线学习网Among the drugs affected by consumption of grapefruit， orange and apple juices are： etoposide， an anticancer agent; beta blockers (atenolol， celiprolol， talinolol) used to treat high blood pressure and prevent heart attacks; and certain antibiotics (ciprofloxacin， levofloxacin， itraconazole). More drugs were expected to be added to the list as the research continued.

学习啦在线学习网受柚子，橙子，和苹果汁影响的药物有：抗癌作用剂依托泊苷;用来治疗高血压和防止心脏病发作的β-受体阻滞药(阿替洛尔，塞替洛尔，他林洛尔);某些抗生素(环丙沙星，氧氟沙星，伊曲康唑)。随着研究的进行将会有更多的药物加入到这个列表中。

学习啦在线学习网Bailey said patients should consult with a doctor about taking medications with juice， and stick to plain water when taking most medications.

学习啦在线学习网贝利说病人用果汁送服药物时应咨询医生的意见，并且服用大多数药物时应坚持用白开水送服。

托福阅读中关于猫的谚语和俚语

1. 猫cat一词来自古英语catt，威尔士语叫做cath，西班牙语是gato，法语叫chat，德语则是kat，他们都源于拉丁语catus、 cattus或者catta，表示家猫domestic cat，相应野猫wildcat的拉丁语就是feles。英文里常常把cat叫做pussycat，就跟我们把猫叫做猫咪一样吧?日语的猫读作ねこ neko。

Rub someone's fur the wrong way，“反摸猫毛”，意思是激怒某人;

Make the fur fly，“让毛飞起来”，意思是开始一场争斗;

托福阅读背景之深海生物的生存

学习啦在线学习网Once it seemed that the ocean floor was a desert of darkness. As everyone knew， sunlight was what made life possible by fueling photosynthesis， and sunlight can penetrate only the first few hundred yards of the ocean’s great depths. Lower， a few creatures might still eke out a living by scrounging the organic detritus that drifts down from the surface of the sea. But thousands of feet down， in the utter blackness at the ocean’s bottom， there could be practically nothing.

学习啦在线学习网Then， in 1977， underwater explorers discovered that there was in fact something， and quite a lot of it. At mid-ocean ridges， where new ocean floor rises up as molten rock from Earth’s interior， where cold seawater mixes with the rising magma and， heated to 650 degrees， spews back up through chimney-shaped hydrothermal vents， researchers stumbled across bustling ecosystems. Clinging to the sides of the chimneys were thick white mats of bacteria; around them were eight-foot-long stalk-shaped worms， rocking in the water， while eyeless shrimp seethed around the chimneys like maggots. All were thriving on the energy bound up in the vents’ sulfur compounds. The seafloor might still be dark， but now it was known to be dotted with gardens.

学习啦在线学习网In just the past eight years， however， underwater explorers have discovered that this picture is still incomplete： there is light at the bottom of the sea. Hydrothermal vents glow， and while the light is too faint to be perceived by the human eye， that hardly means it is without significance. Physicists maintain that although some of the light may be created by the intense heat， much of it must be attributed to some as-yet- unknown process. Biologists， meanwhile， say there is sufficient light at these vents for photosynthesis to take place. Researchers can’t say yet whether any creatures are actually living off this light， but if they are， they will represent the first known instance of natural photosynthesis without sunlight. The evolutionary implications may run deeper： it’s possible not only that this deep light is fueling photosynthesis now， but that， 3.8 billion years ago， it got the whole process started.

无处不在的细菌：没有阳光就不能进行光合作用，地面生物就无法生存了。但是在2000—3000米深的海底，没有阳光的地方，各种生物又是以什么为食物来维持生命呢?科学家从海底采取的水样中发现了奥妙。原来在水下2500到3000米的海底常有温泉出现，这些温泉喷涌出高达350摄氏度的水流。海底热泉水从地下带上来许多硫酸盐，硫酸盐在高温高压下变成了有臭鸡蛋味的硫化氢，一些以硫化氢为营养的细菌以极快的速度繁衍。细菌通过摄取温泉里丰富的化合物获得能量，它们帮助温泉水把周围变成一片生机勃勃的海底绿洲。小动物就以细菌为食，大动物又以小动物为食，这样就形成了新的食物链。
