Free Statins With Fast Food Could Neutralize Heart Risk
Fast food outlets could provide statin drugs free of______(51)so that customers can re-duce the heart disease dangers of fatty food,researchers at Imperial College London______(52)in a new study.
Statins reduce the______(53)of unhealthy"LDL"cholesterol in the blood.A wealth of trial data has proven them to be highly effective at______(54)a person's heart attack risk.
In a paper published in the American Journal of Cardiology,Dr. Darrel Francis and col-leagues calculate that the reduction in heart attack risk offered by a statin is______(55)to off-set the increase in heart attack risk from______(56)a cheeseburger and drinking a milk-shake.
Dr. Francis,from the National Heart and Lung Institute at Imperial College London,who is the senior author of the study,said,"Statins don't cut out all of the______(57)effects of che-eseburgers and French fries .It's better to avoid fatty food altogether. But we've worked out that in terms of your______(58)of having a heart attack,taking a statin can reduce your risk to more or less the same______(59)as a fast food meal increases it."
"It's ironic that people are free to take as many unhealthy condiments in fast food outlets as they______(60),but statins,which are beneficial to heart health,have to be prescribed.It______(61)sense to make risk-reducing stains available just as easily as the unhealthy condi-ments that are provided free of charge .It would cost less than 5 pence per______(62）-not much different to a sachet of sugar,"Dr. Francis said.
When people engage in risky behaviours like driving or smoking,they're encouraged to take______(63)that lower their risk,like______(64)a seatbelt or choosing cigarettes with flu-ters .Taking a statin is a rational way of______(65)some of the risks of eating a fatty meal.

  Food Fright
  Experiments under way in several labs aim to create beneficial types of genetically modified(GM)foods,including starchier potatoes and caffeine-free coffee beans.Genetic engineers are even trying to transfer genes from a cold-water fish to make a frost-resistant tomato.A low-sugar GM strawberry now in the works might one day allow people with health problems such as diabetes to enjoy the little delicious red fruits again.GM beans and grains supercharged with protein might help people at risk of developing kwashiorkor. Kwashiorkor,a disease caused by severe lack of protein,is common in parts of the world where there are severe food shortages.
  Commenting on GM foods,Jonathon Jones,a British researcher,said,"The future benefits will be enormous,and the best is yet to come."
  To some people,GM foods are no different from unmodified foods."A tomato is a tomato," said Brian Sansoni,an American food manufacturer.
  Critics of GM foods challenge Sansoni's opinion.They worry about the harm that GM crops might do to people,other animals,and plants.
  In a recent lab study conducted at Cornell University,scientists tested pollen made by Bt corn,which makes up one-fourth of the U .S.corn crop.The scientist sprinkled the pollen onto milkweed,a plant that makes a milky juice and is the only known food source of the monarch but-terfly caterpillar. Within four days of munching on the milkweed leaves,almost half of a test group of caterpillars had died."Monarchs are considered to be a flagship species for conservation,"said Cornell researcher Linda Raynor."This is a warning bell."
  Some insects that are not killed by GM foods might find themselves made stronger. How so? The insecticides used to protect most of today's crops are sprayed on the crops when needed and decay quickly in the environment.But GM plants produce a continuous level of insecticide.Insect species feeding on those crops may develop resistance to the plants and could do so in a hurry, say the critics.Insects may also develop a resistance to the insecticide Bt.
  At the forum on GM food held last year in Canada,GM crops that have been made resistant to the herbicide might crossbreed with wild plants,creating"superweeds"that could take over whole fields.
  So where do you stand?Should GM foods be banned in the United States,as they are in parts of Europe?Or do their benefits outweigh any of the risks they might carry?
  Why is the case of the pollen-sprayed milkweed cited in Paragraph 6?
  A: It is cited to show GM foods can kill insects effectively.
  B: It is cited to show GM foods contain more protein.
  C: It is cited to show GM foods also have a dark side.
  D: It is cited to show GM foods may harm crops.

  More Than 8 Hours Sleep Too Much of a Good Thing
  1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
  2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling re-freshed after a night's sleep than 8-hour sleepers.
  3 These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night.He added that“it might be a good idea” for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cau-tioned that more research is needed to confirm this.
  4 Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
  5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep ques-tionaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
  6 Kripke found that people who slept between 9 and 10 hours each night were more like-ly to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.
  Paragraph 2______
  A: Kripke's Research
  B: Dangers of Habitual Shortages of Sleep
  C: Criticism on Kripke's Report
  D: A way of Overcoming Insomnia
  E: Sleep Problems of Long and Short Sleepers
  F: Classification of Sleep Problems

  Learn About Noble Gases（惰性气体）
  1 Have you ever ridden on a balloon?Many tourist spots offer balloon rides in order for people to see
  the beauty of a place from above.A balloon contains a noble gas called helium（氦）.Formerly,balloons con-
  tamned hydrogen but hydrogen is very flammable and dangerous when uncontrolled.Therefore,people shifted
  to helium,which is safer. Helium is safe because it has the properties of the noble gases.
  2 People once believed that noble gases couldn't chemically react at all.For this reason,they were
  called inert gases（惰性气体）.They were also listed under Group 0 in the old periodic table because scien-
  tists believed that the gases have zero valence（价）electrons in their outer shell.This was later proven to be
  untrue when some noble gas compounds were discovered.
  3 The gases are elements,which share similar properties.These properties include being monoatomic,
  colorless,odorless,being able to conduct electricity,and having low chemical reactivity.Noble gases
  include helium,neon,argon,krypton,xenon and radon.These are all found in Group 18,in the right most
  column of the periodic table.If you look at the periodic table,you will notice that these elements are the only
  ones which do not have a charge. Helium has the lowest molecular（分子的）weight while radon is the
  heaviest.
  4 Remember that chemical reactions occur because atoms have valence electrons,which are electrons
  in their outer shell.When the outer shell is"unfilled"or the required number of electrons is not yet corn-
  plete,the atom is more reactive.Noble gases have a full outer shell,meaning that they have complete elec-
  trons in their outer shell.This complete number varies.For instance,the outer shell of helium has 2 valence
  electrons while the outer shell of xenon has 8 electrons.Nowadays,there remains to be a few noble gases
  because of the low chemical reactivity of these said gases.
  5 because of their properties,noble gases have many important applications.They are widely used in
  medicine and industries. For instance , liquid helium is used for superconducting magnets（磁体）.These
  magnets are very important in physics and medicine.When a doctor suspects that a person's brain has been
  damaged,he might request for Magnetic Resonance Imaging(MRI).MRI allows the doctor to"see"the
  brain,without operating on the patient.
  Paragraph 3____________
  A:How were Noble Gases Discovered?
  B:What is the Periodic Table?
  C:What are the Applications of Noble Gases?
  D:How were Noble Gases Understood in the Past?
  E:What Causes the Low Chemical Reactivity of Noble Gases?
  F:What are Noble Gases?

  Cell Phone Lets Your Secret Out
  Your cell phone holds secrets about you.Besides the names and _____________(51)that you've pro-
  grammed into it,traces of your DNA linger on the device,according to a new study.
  DNA is genetic material that______________(52)in every cell.Like your fingerprint,your DNA is unique
  to you一 _____________（53)you have an identical twin.Scientists today routinely analyze DNA in blood,
  saliva,or hair left _____________(54)at the scene of a crime.The results often help detectives identify
  _____________(55)and their victims.Your cell phone can reveal more about you _____________(56)you might
  think.
  Meghan J.McFadden,a scientist at McMaster University in Hamilton,Ontario,heard about a crime in
  which the suspect bled onto a cell phone and later dropped the______________(57).This made her wonder
  whether traces of DNA lingered on cell phones even when no blood was involved.______________(58)she and
  colleague Margaret Wallace of the City University of New York analyzed the flip-open phones of 10 volun-
  teers.They used swabs to collect______________(59)traces of the users from two parts of the phone:the
  outside,where the user holds it,and the______________(60),which is placed at the user's ear.
  The scientists scrubbed the phones using a solution made mostly______________(61)alcohol.The aim of
  washing was to remove all detectable traces of DNA.The owners got their phones______________(62)for
  another week.Then the researchers collected the phones and repeated the swabbing of each phone once
  more.
  The scientists discovered DNA that _____________(63)to the phone's speaker on each of the phones.
  Better samples were collected from the outside of each phone,but those swabs also picked up DNA that be-
  longed to other people who had apparently also handled the phone.______________(64),DNA showed up even
  in swabs that were taken immediately after the phones were scrubbed.That suggests that washing won't remove
  all traces of evidence from a criminal's device.So cell phones can now be added to the
  ______________(65)of clues
  that can clinch a crime-scene investigation.
