7．It may be safer to make a salad on your toilet seat than your kitchen cutting board．
That's because there is 200times more germs （细菌） on your cutting board，says Chuck Gerba，a world-famous germ expert at the University of Arizona，US．
When looking at the amount of germs in an average home，Gerba said，researchers have found that the place with the most germs is the kitchen sponge （海绵）．"The sponge is a happy home for germs．It's wet and it's sucking up food all of the time，"he said．He added that you could squeeze （挤压） as much as 10million germs out of one sponge without any difficulty．
Gerba explained that there is a smaller amount of germs inside a home's toilet bowl after a person flushes （冲洗） than there is in a kitchen sink （水槽）．
"That's why dogs drink out of the toilet．They're a lot smarter than you think，"he joked．
He said people usually clean their bathroom with cleaning products because they are afraid of getting diseases，but they don't clean the kitchens with the same effort．
Better cleaning is also needed in the laundry room．He explained that most people only wash their laundry for a short amount of time with cold water．That makes it possible for germs to survive through the wash．

35．Which can be the best title for this passage？D
A．A report on germs
B．An expert on germs
C．A germ expert's research
D．Kitchen germs
36．The thing with the most germs at home isC．
A．the toilet seat
B．the toilet bowl
C．the kitchen sponge
D．the kitchen cutting board
37．In the germ expert's opinion，the place with most germs at home isA．
A．the kitchen
B．the bathroom
C．the sitting room
D．the laundry room
38．Which of the following is true according to Gerba's research？D
A．Dogs drink out of the toilet because they're smarter．
B．People usually clean the kitchens with cleaning products．
C．The toilet bowl is 200times cleaner than the cutting board．
D．It's not enough to clean the laundry room only with cold water．

38．D 细节理解题．根据文章最后一段的内容He explained that most people only wash their laundry for a short amount of time with cold water．That makes it possible for germs to survive through the wash．人们习惯用冷水冲洗他们的洗衣房，那样的话有利于细菌的滋生，由此可知，冷水冲洗是不足够让它干净的．结合选项，故选D

12．Basically，without the possibility of failure，there is little possibility of success．Education is in danger of becoming a branch of the entertainment industry．Although education should indeed be entertaining where possible，it cannot always be fun．Often，it needs the"hard yards"．
    Some educationalists feel that if something causes worry it should be avoided at all costs．I would disagree．Facing up to challenges helps develop children．Avoiding challenges can severely limit their potential．Tougher children are able to try and fail．The less tough may simply fail to try anything new．
    I'm not advocating putting children under pressure．The real debate is perhaps what pressures are unavoidable．It's not about"throwing children into the deep end"，but rather encouraging them to put their foot in the water and giving them the skills to float．
    This latter approach is basically the work I and my team do at the University of Hull．We measure mental toughness and then provide interventions to improve this．These interventions include psychological skills such as goal setting，relaxation and thought control．So，for example，many children will say："What happens if it goes wrong？"We work hard to change this so that the sentence reads："What happens if it goes right？"One word difference，but a world away when thinking about challenges．
    We try to help children deal more effectively with life using a three-step approach．Firstly，it is important to set realistic and achievable goals．Then it is a matter of finding out what factors （因素） are helping children to achieve these goals and what factors are working against this．The final step is to discover which of these factors can be controlled，or at least influenced，and what factors the child is in reality stuck with．Redirecting children's energies to movable obstacles （障碍） can produce huge life changes．
    However，I think that for most of us we have become stress averse （反对的） and overreact to it．It has always been there，and it has always been the case that some people enjoy it，some need help to deal with it and some people's lives are ruined by it．
    Showing our children that stress can be faced with and beaten offers them a way forward．The more a fear is avoided，the bigger it gets．

67．From the passage，we know the writer believesA．
A．education needs challenges
B．education should always be fun
C．children should avoid facing challenges
D．the more challenges，the better for the children
68．The writer disagreed with some educationalists becauseC．
A．some children are less tough
B．some pressures are avoidable
C．some challenges do good to children
D．some children are unaware of their potential
69．What do the writer and his team do at the University of Hull？D
A．Record what the children do in stressful situations．
B．Make the children tougher mentally and physically．
C．Put the children under pressure by giving them challenges．
D．Give the children challenges and suggest suitable approaches．
70．What is the correct attitude towards stress according to the writer？D
A．We should try our best to avoid stress．
B．We should love stress because stress is unavoidable．
C．We should put ourselves to the test in stressful situations．
D．We should experience stress and learn skills to deal with it．

Besides hosting events for holidays such as the Fourth of July and Halloween，each high school often has their own special events．One day might be"Inside Out/Backwards Day，"where students and teachers should wear their clothes reversed all day，perhaps walk and speak backwards，and even go to classes in opposite order．And some schools hold competitions where，if certain academic goals are met，the principal will kiss a pig，shave his mustache，or dress as a woman for the day．

16．A newly discovered planet looks just right for life as we know it，according to an international group of astronomers．Orbiting a star about 500light-years away，the planet called Kepler-186f is about the same size as Earth．It orbits its star at the right distance for liquid water on the surface．That is a necessary condition for life as we know it．
But it is not exactly like Earth，NASA planetary scientist Elisa Quintana said．"It's more of an Earth's cousin．It's not an Earth's twin．It shares the same characteristics as Earth，but their parent stars are very different，"said Quintana．
Kepler-186f orbits a star that is smaller and cooler than our sun．But，writing in the journal Science，the astronomers say the planet appears to be a closer relative than most of the hundreds of others discovered so far．Some are massive gas-covered giants with thick，crushing atmospheres．Others orbit too close to their stars and are too hot for life．
Two planets discovered last year are in the right orbit and might be good candidates for life，Quintana says，but they are a bit bigger than Earth．"For the first time，we can actually say we now have a planet that is both Earth-sized and orbits in its star's habitable zone，"she said．
It may be the first time，but it probably is not the last，says Massachusetts Institute of Technology astrophysicist Sara Seager．"We've been waiting decades to understand how common habitable planets might be，and it's looking like they're really common．And this gives us excitement and motivation to take the next step，"said Seager．
The next step would be to look for signs of life in the atmospheres of these distant worlds．That would take a more sophisticated （高端的；复杂的） space telescope．But budget cuts threaten that mission，says University of California at Los Angeles astrophysicist Ben Zuckerman．"In principle，we could do this in the next few decades．But in practice，because there's no money，it's not gonna happen．It's not gonna happen in my lifetime，for example．"
Leaving earthbound concerns behind，NASA's Elisa Quintana believes that when the next-generation space telescope is launched，it will find that we are not alone in the universe．

63．What does the underlined word"That"（Paragraph 1）refer to？B
A．The right distance． B．Liquid water．
C．The right size． D．A star．
64．According to Elisa Quintana，Kepler-186fA．
A．is more of an Earth's cousin than an Earth's twin
B．has a lot in common with Earth，including their parent stars
C．is a lot bigger than Earth
D．is smaller and cooler than our sun
65．Ben Zuckerman and Elisa Quintana would probably agree thatC．
A．they can continue their research without worrying about money
B．it is the last time that they have discovered such a planet
C．a sophisticated space telescope plays an important role in their research
D．Earth is the only planet where we can find signs of life
66．Which of the following would be the best title for the passage？D
A．Where there is water，there is life
B．A planet exactly like Earth found
C．Life discovered on Kepler-186f
D．New Earth-size planet found．
