【題目】根據(jù)短文理解，選擇正確答案。
As we know, DNA testing is very useful for crime fighting. But now crime fighters could have a new tool at hand. Researchers have developed a cutting-edge (前沿的) technique to identify human hair. Their test is quicker than DNA analysis techniques currently used by the police.
DNA testing is commonly used for identification because DNA is unique to each individual. However, environmental and chemical processes can degrade(降解) DNA, limiting its usefulness over time. Protein (蛋白質(zhì)) in hair, on the other hand, is more stable than DNA but can also have variations (變異體) that may be unique to the individual.
“Our analysis process can be used universally, ”says Ms. Huang, “One of our samples even included dyed hair and the test was 100 per cent accurate. The test was able to distinguish East Asians, Caucasians and South Asians.”
Dr. Beauchemin says she has got in touch with law enforcement agencies about using the new technology. She is also planning to collect more hair samples and continue her research with a goal of finding where exactly in the world hair sample is from, to look for more races and determine specific age.
“We are in a very similar place with protein-based identification to where DNA testing was during the early days of development,” said chemist Brad Hart. “This method will be a game-changer, and while we've made a lot of progress toward improving it, there are steps to go before this new technique is able to reach its full potential.”
（1）What's the main purpose of the text?
A.To analyze crime scenes.
B.To distinguish different races.
C.To show the usefulness of DNA testing.
D.To introduce a new identification method.
（2）Which will be the most useful in identifying a person according to Brad Hart?
A.Chemical materials.
B.Protein in hair.
C.DNA variations.
D.Blood sample.
（3）What's the advantage of the protein-based identification over DNA testing?
A.Stability.
B.Popularity.
C.Security.
D.Convenience.
（4）What can be inferred from the last paragraph of the text?
A.DNA testing will soon reach its full potential.
B.Protein-based identification remains to be improved.
C.Protein-based identification has replaced DNA testing.
D.DNA testing develops as rapidly as protein-based identification.

Testing the five-second rule
You may have seen a friend drop food on the floor, pick it up, and eat it, while declaring, “Five-second rule! ” It's said that food dropped on the floor for five seconds or less is still likely to be clean. .
Students at Britain's Aston University, led by microbiology professor Anthony Hilton, tested the rule and found it to have some scientific basis. The study's results show that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer, according to Hilton.
The students also found that the type of flooring where the dropped food lands has an effect. Bacteria are most likely to transfer from tiled (鋪瓷磚的) surfaces to moist food when the food has stood there for more than five seconds.
Therefore, consumers should still be cautious. “However, the findings of this study will bring some light relief to those who have been employing the five-second rule for years, despite a general consensus that it is purely a myth,” professor Hilton said in a statement.
The research team at Aston also surveyed 500 people to find out who employs the five-second rule. Of the people surveyed, 87% said they would eat food dropped on the floor, or have done so in the past. “Our study showed people are also more likely to follow the five-second rule, which our research has shown to be much more than an old wives' tale,” Hilton says.
Still, scientists say you should be careful about eating food dropped on the floor, especially if you have doubts about the cleanliness of the surface.
A. But is that true?
B. Carpeted surfaces posed the lowest risk.
C. Of those people, the majority were women.
D. We've just lost our last excuse to eat food off the floor.
E. Usually people recover from the infection in five to ten days.
F. There is still a risk of infection if certain bacteria are present on the dropped surface.
G. A biologist points out that one in six Americans get sick from food poisoning every year.
