20．Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time，according to the findings of research carried out at Aston University's School of Life and Health Sciences．The findings suggest there may be some scientific basis of the"5-second rule"-the belief about it being fine to eat food that has only had contact with the floor for five seconds or less．Although people have long followed the‘5-second rule'，until now it was unclear whether it actually helped．
The study，undertaken by final year Biology students and led by Anthony Hilton，Professor of Microbiology at Aston University，monitored the transfer of the common bacteria from a variety of indoor floor types as carpet，cement floor to toast，pasta，biscuit and a sticky sweet when contact was made from 3to 30seconds．The results showed that：time is a significant factor in the transfer of bacteria from a floor surface to a piece of food，and the type of flooring the food has been dropped on has an effect，with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5seconds．Professor Hilton said，"Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time．"
The Aston team also carried out a survey of the number of people who employ the‘five-second rule'．The survey showed that：87% of the people surveyed said they would eat food dropped on the floor，or already have done so.55% of those that would，or have eaten food dropped on the floor are women.81% of the women who would eat food from the floor would follow the‘5-second rule'．Professor Hilton added，"Our study showed that a surprisingly large majority of people are happy to consume dropped food，with women the most likely to do so．But they are also more likely to follow the‘5-second rule，which our research has shown to be much than an old wives'tale．"

24．According to the passage，which of the following is true？D

C．The food dropped on the carpet shares the same potential of being polluted with the food dropped on the cement floor．

A．Contrast B．Example C．Time D．Space
26．How did Professor Hilton feel after analyzing how many people chose to eat dropped food？D

19．This month，Germany's transport minister，Alexander Dobrindt，proposed the first set of rules for autonomous vehicles（自主驾驶车辆）．They would define the driver's role in such cars and govern how such cars perform in crashes where lives might be lost．
The proposal attempts to deal with what some call the"death valley"of autonomous vehicles：the grey area between semi-autonomous and fully driverless cars that could delay the driverless future．
Dobrindt wants three things：that a car always chooses property（财产） damage over personal injury； that it never distinguishes between humans based on age or race； and that if a human removes his or her hands from the driving wheel-to check email，say-the car's maker is responsible if there is a crash．
"The change to the road traffic law will permit fully automatic driving，"says Dobrindt．It will put fully driverless cars on an equal legal footing to human drivers，he says．
Who is responsible for the operation of such vehicles is not clear among car makers，consumers and lawyers．"The liability（法律责任） issue is the biggest one of them all，"says Natasha Merat at the University of Leeds，UK．
An assumption behind UK insurance for driverless cars，introduced earlier this year，insists that a human"be watchful and monitoring the road"at every moment．
But that is not what many people have in mind when thinking of driverless cars．"When you say‘driverless cars'，people expect driverless cars．"Merat says．"You know-no driver．"Because of the confusion，Merat thinks some car makers will wait until vehicles can be fully automated without operation．
Driverless cars may end up being a form of public transport rather than vehicles you own，says Ryan Calo at Stanford University，California．That is happening in the UK and Singapore，where government-provided driverless vehicles are being launched．
That would go down poorly in the US，however．"The idea that the government would take over driverless cars and treat them as a public good would get absolutely nowhere here，"says Calo．

A．A place where cars often break down．

C．It should not cause deadly traffic accidents．
D．It should involve no human responsibility．

C．the US                          D．Germany

18．Cold weather has a great effect on how our minds and our bodies work．Maybe that is why there are so many expressions that use the word cold．For centuries，the body's blood has been linked closely with the emotions．People who show no human emotions or feelings，for example，are said to be cold-blooded．Cold-blooded people act in merciless ways．They may do cruel things to others，and not by accident．For example，a newspaper says the police are searching for a cold-blooded killer．The killer murdered someone，not in self-defense．He seemed to kill with no emotion．
Cold can affect other parts of the body，the feet，for example．Heavy socks can warm your feet，if your feet are really cold．But there is an expression-to get cold feet-that has nothing to do with cold or your feet．The expression means being afraid to do something you had decided to do．For example，you agree to be president of an organization．But then you learn that all the other officers have given up the position．All the work of the organization will be your responsibility．You are likely to get cold feet about being president when you understand the situation．
Cold can also affect your shoulder．You give someone the cold shoulder when you refuse to speak to them．You treat them in a distant，cold way．The expression probably comes from the physical act of turning your back toward someone，instead of speaking to him face-to-face．You may give a cold shoulder to a friend who has not kept a promise he made to you．Or，to someone who has lied about you to others．
A cold fish is not a fish．It is a person．But it is a person who is unfriendly，unemotional and shows no love or warmth．A cold fish does not offer much of himself to anyone．
Out in the cold is an expression often heard．It means not getting something that everybody else got．A person might say that everybody but him got a pay raise．He was left out in the cold．And it is not a pleasant place to be．

A．cold weather has a great effect on human bodies．
B．many English expressions contain the word cold．
