試題詳情
Look closely at your hands.Are they clean？It doesn't matter how many times you wash your hands，tiny microbes（微生物）still stay on them.But don't worry.Most microbes don't harm you.
Now scientists say the microbes on our hands could be used in a surprising way：fighting crime.According to a recent survey microbes as well as fingerprints（指紋）could be used to identify the criminal.
Everyone has his own set of microbes on the hands.That is to say，if you and your best friend were able to see and compare all the microbes on your hands，your hands probably would look different.Some microbes only show up on your hands while others live only on your friend's hands.
When you work on a computer you leave the microbes from your hands on the keyboard.The scientists can easily tell the owner of the keyboard by looking at the microbes on it.Even if you don't leave your fingerprints behind，your microbes may give you away.
Noah Fierer，a scientist，says，"You can only clean a fingerprint，but you can't sterilize（使無菌）a surface just by wiping（擦）it off."He says that scientists have a lot more work to do before the microbe is used as a useful tool.
（1）According to the passage， DDcould be used to identify the criminal.
A.fingerprints
B.scientists' hands
C.microbes
D.fingerprints and microbes on people's hands
（2）Paragraph 3 tells us that DD.
A.our hands look similar
B.the microbes will make the keyboard dirty
C.we should compare hands often
D.we have our own sets of microbes
（3）When you work on computer，the microbes BB.
A.just stay on our hands
B.also stay on the keyboard
C.will do harm to you
D.will disappear
（4）From Noah Fierer we know that CC.
A.fingerprints are no longer useful in fighting crime
B.microbes can be found on everyone's hands
C.unlike microbe，fingerprints can be cleaned if people wipe them
D.the microbe is used as a useful tool
