such as bird flu，AIDS, SARS are infectious diseases. Infectious diseases are difficult to cure.
2. What do you know about cholera?
Cholera is the illness caused by a bacterium called Vibrio cholerae. It infects people’s
intestines(肠), causing diarrhea and leg cramps (抽筋).The most common cause of cholera is by
someone eating food or drinking water that has been contaminated(污染) with the bacteria.
Cholera can be mild(不严重的) or even without immediate symptoms(症状), but a severe case
can lead to death without immediately treatment.
3. Do you know how to prove a new idea in scientific research?
Anybody might come out with a new idea. But how do we prove it in scientific research?
There are seven stages in examining a new idea in scientific research. And they can be put in the
following order. What order would you put the seven in? Just guess.
Find a problem→ Make up a question→ Think of a method→ Collect results→
Analyse the results→ Draw a conclusion→ Repeat if necessary
