[00:06.79]Jane works1 at the Center for Disease2 Control and prevention
[00:12.12]as a disease detective.
[00:15.46]Listen to the tape and answer the questions.
[00:19.91]The Diseases3 detective.
[00:23.46]Jane is one of the experts at the Center for Disease Control and Prevention.
[00:30.62]People at the center study how the diseases start and spread,
[00:36.57]and as the names shows,try to control and prevent diseases.
[00:43.42]We ask Jane about her work.
[00:46.97]Part One  Well,I have to be a detective.
[00:52.61]I go to a place where disease has broken out
[00:57.44] and I look for clues about the diseases.
[01:02.17]I try to find as much information as I can about what happened.
[01:08.65]Who were sick,what are the signs,do they have a fever,
[01:14.81]a headacheor a sore throat,when did they get sick?
[01:20.59]When I have collected the information,
[01:24.74]I use it to find out what caused the problem.
[01:29.60]We can use what we learn to prevent others from getting sick.
[01:35.24]Jane,and other disease detective at the center do their jobs in different ways.
[01:42.61]Some detectivesworking in laboratories5 where they examine test and samples.
[01:49.09]Others travel to towns or villages
[01:53.63]where there are diseases and talk to people who are sick.
[01:58.60]All of the experts of the center know that their work is important.
[02:04.55]If they do their jobs well,they will save lives.
[02:09.80]Part Two 
[02:13.07]How often do you actually go to the places where a new disease has broken out?
[02:19.42]B:Oh,It happens every now and then,probably about every three month or so.
[02:26.78]A:How do you find about new diseases?
[02:31.35]B:We will usually hear from doctors and hospitals.
[02:36.11]If they notice anything strange,they will give us a call and ask for a help.
[02:42.35]If we think it is necessary,we'll go to the place when people are getting sick.
[02:49.12]A:Are you afraid of catching6 the diseases you are studying?
[02:54.47]B:Well,yes sometimes,but we are always very careful.
[03:00.43]If you know what you are doing,you can protect yourself.
[03:05.70]Besides,I'm more afraid of what might happen if we don't find out what kind of disease it is.
[03:13.15]A:What can ordinary people do to protect themselves?
[03:18.71]B:The best thing you can do is simply to wash your hands often,
[03:24.17]and try to avoid crowded places.
[03:28.54]Wearing a mask over your face may help,
[03:33.19]but it is probably not necessary unless you are caring for a sick person.
[03:39.85]It is also important to see a doctor if you get sick,
[03:44.91]so that you don't spread disease without knowing it.
[03:53.06]Work Book  Unit 7  Listening
[03:59.31]Ken4 is learning7 about HIV/AIDS in school.
[04:03.85]His teacher has asked him to interview a doctor at a local hospital
[04:10.02] and write a report about basic HIV/AIDS facts.
[04:15.58]Listen to the interview and help Ken prepare the report.
[04:21.22]Part One  A:Hello,Dr Wards8.
[04:25.98]  Thank you for letting me interview you.
[04:29.92]B:You are welcome.Now,what would you like to know?
[04:34.89]A:Well,my first question is about the name of the disease.
[04:41.16]What does AIDS stand for?
[04:45.20]B:When we talk about AIDS,we often use the term HIV/AIDS.
[04:51.45]HIV is the virus that causes AIDS.
[04:56.49]AIDS stands for Acquired Immune9 Deficiency10 Syndrome11.
[05:02.26]A:Acquired Immune Deficiency Syndrome?
[05:07.30]OK,got it.But I'm not sure I understand what it means.
[05:13.78]B:Well,to acquire something is to get something,
[05:19.24]so acquired means that you can get infected with the disease,
[05:24.70]Immune comes from Immune system,
[05:29.56]the system that protects your body from diseases.
[05:34.32]A:So Acquired Immune
[05:38.26]tells us that this is the disease that we can get from other people.
[05:44.22]And that it has something to do with our immune system.
[05:48.97]What exactly does AIDS do to our immune system?
[05:54.25]B:That's what the next word tells us

[05:58.09]If something is deficient,it means that it isn't functioning probably.
[06:04.56]It isn't working in the way it should.
[06:08.51]So Acquired Immune Deficiency
[06:13.19]means that even though we were born with a good immune system
[06:18.64] we have now got the disease that breaks down the immune system.
[06:24.71]A:Wow,that's terrible.
[06:28.36]So what happens when someone's immune system doesn't work?
[06:34.24]B:Well,to put it simply,he or she gets sick lot.
[06:39.57]The last word in AIDS 'Syndrome',
[06:44.01]means all the bad things that happen to your body,
[06:48.76]when the immune system doesn't work.
[06:53.13]Part Two  People who die of AIDS actually don't 'die' of AIDS.
[06:59.79]When a person infected with HIV develops AID.
[07:05.25] She or she easily gets sick.
[07:09.40]A person with AIDS has a very weak immune system.
[07:14.44]Many common diseases can be cured in patients whose immune system functions well.
[07:21.60]But when they enter the body of a person with AIDS,they can kill him or her.
[07:28.08]Many AIDS patients die of infections or serious colds.
[07:34.03]But there are also many diseases that we have never heard of.
[07:39.36]If your immune system is working,they may not be able to any harm.
[07:46.13]But because the immune system has been weakened12 the disease can't be cured.
[07:52.48]They will grow stronger and stronger
[07:56.34]until one day they kill the patient with AIDS.
[08:01.49]Therefore,much of the treatments AIDS patients receives
[08:07.26] is means to help the body defend itself against diseases
