  A New Cause of Suffering
  A conference on obesity（肥胖症）was recently held in Vienna. Two thousand experts
  from more than fifty countries attended the conference.According to statistics,1.2 billion
  people worldwide are overweight,and 250 million are too fat.Obesity is rapidly becoming a
  new cause of suffering.
  Professor Friedrich Hopichler of Salzberg said:"We are living in the new age but with
  the metabolism（新陈代谢）of a stone-age man. I have just been to the United States. It is
  really terrible. A pizza（比萨饼）shop is appearing on every corner. We have been
  occuoied by fast food and Coca-Cola-ization."
  Many of the experts stressed that obesity was a potential killer.Hopicnier saia:
  "Eighty per cent of all diabetics（糖尿病人）are too fat,also fifty per cent of all patients with
  high blood pressure and fifty per cent with fatty（脂肪的）tissue complaints. Ten per cent
  more weight means thirteen per cent more risk of heart disease.Reducing one's weight by
  ten oer cent leads to thirteen per cent lower blood pressure."
  Another expert Hermann Toplak said that the state health services should improve their
  financing of preventive programs,"The health insurance pays for surgery(such as
  reducing the size of the stomach ) when the body-mass index（身体质量指数）is more than
  40.That is equivalent to a weight of 116 kilograms for a height of 1.60 meters.One should
  start earlier."
  Toplak said that prevention should begin in school.“Child obesity has a close relation
  with the time which children spend in front of TV sets."
  Hermann Toplak suggested that more money should be spent on
  A:surgery.
  B:fat people.
  C:preventive programs.
  D:state health services.

  Scientists Develop Ways of Detecting Heart Attack
  German researchers have___1___a new generation of defibrillators and earlywarning software aimed at offering heart patients greater protection___2___sudden death from cardiac arrest.
  In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases___3___by disruption to the heart's rhythm. Those most at risk are pa- tients who have___4___suffered a heart attack,and for years the use of defibrillators has proved useful in diagnosing___ 5___ disruptions to heart rhythms and correcting them automat-ically by intervening within seconds. These devices___6___ a range of functions,such as that of pacemaker.
  Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with an implanted defibrillator ___7___of generating a six-channel electrocardiogram(ECG)within the body. This integrated system allows early diagnosis of___8___blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders the evaluation of ECG data___9___.
  The overwhelming___10___of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs.“Many of the current programs only ___11___ into account a linear correlation of the data. We are,however,making use___12___ a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system,”

  Tiny Invaders
  The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
  and to move from place to place.In fact,the human body does its work so well that most people don't think
  about it very much-until they get sick.
  The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
  They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
  are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
  live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
  creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
  good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
  How can you stop these tiny invaders from making you sick?Your skin is the first defense against
  germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
  body through small cuts in the skin or through the mouth,eyes,and nose.
  Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
  destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
  Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
  germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
  germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
  That way you will not get the same illness twice.
  You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune systerm
  strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
  medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
  Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
  antibodies attack it.
  Vaccines can make you sick.
  A:Right
  B:Wrong
  C:Not mentioned
