5．It is found that American students spend less than 15% of their time in school．While there's no doubt that school is important，a number of recent studies reminds us that parents are even more so．A study published earlier this month by researchers at North Carolina State University，for example，finds that parental involvement-checking homework，attending school meetings and events，discussing school activities at home-has a more powerful influence on students'academic performance than anything about the school the students attend．Another study，published in the Review of Economics and Statistics，reports that the effort put forth by parents （reading stories aloud，meeting with teachers） has a bigger impact on their children's educational achievement than the effort devoted by either teachers or the students themselves．And a third study concludes that schools would have to increase their spending by more than $1，000 per pupil in order to achieve the same results that are gained with parental involvement．
So parents matter．But it is also revealed in researches that parents，of all backgrounds，don't need to buy expensive educational toys or digital devices for their kids in order to give them an advantage．They don't need to drive their offspring to enrichment classes or test-preparation courses．What they need to do with their children is much simpler：talk．
But not just any talk．Recent research has indicated exactly what kinds of talk at home encourage children's success at school．For example，a study conducted by researchers at the UCLA School of Public Health and published in the journal Pediatrics found that two-way adult-child conversations were six times as potent in promoting language development as the ones in which the adult did all the talking．Engaging in this reciprocal（雙向的） back-and-forth gives children a chance to try out language for themselves，and also gives them the sense that their thoughts and opinions matter．
The content of parents'conversations with kids matters，too．Children who hear talk about counting and numbers at home start school with much more extensive mathematical knowledge，report researchers from the University of Chicago．While the conversations parents have with their children change as kids grow older，the effect of these exchanges on academic achievement remains strong．Research finds that parents play an important role in what is called"academic socialization"-setting expectations and making connections between current behavior and future goals．Engaging in these sorts of conversations has a greater impact on educational accomplishment．
72．Parents are even more important than schools in thatD．
A．parental involvement makes up for what schools are not able to do
B．teachers and students themselves do not put in enough effort
C．parental involvement saves money for schools and the local government
D．students may well make greater achievements with parents'attention
73．It can be inferred from the 2nd paragraph thatC．
A．educational toys are unaffordable nowadays
B．digital devices can give children an advantage
C．some parents believe in enrichment classes
D．talking with children is a very simple task
74．The word"potent"is closest in meaning toA．
A．powerful       B．difficult       C．necessary                D．resistant
75．Which of the following will more encourage children's success at school according to the passage？B
A．Parents order their children to stop playing video games．
B．Parents discuss with their children the possible future career．
C．Parents lecture their children on getting too low marks on tests．
D．Parents introduce colleges around the US to their children．

20．Do you know what Fear and Faith have in common？Fear believes in a negative future．Faith believes in a positive future．Both believe in something that has not yet happened．So I ask you，if neither the positive nor negative future has happened yet then why not choose to believe in the positive future？
I believe during these challenging times we have a choice between two roads：the positive road and the negative road．And （our bus can't be on two roads） at the same time．So we have to make a choice and this choice determines our belief about the future and the attitude and actions we bring to the present．
I'm not saying we shouldn't have any fear．There are times when fear is a gift．A healthy dose（劑量） of fear causes us to examine our situation and plan for the future．It moves us to smell the cheese and expect change．When used wisely it allows us to manage risk and make better decisions．Some fear is good．
However，what I have observed lately is a supersized，huge dose of fear that is spreading the hearts and minds of far too many people．This oversized fear is causing leaders and their organizations to either act unreasonably or to not act at all．They are either hurrying in a million different directions because of fear．In both cases，fear is leading them to take the negative road to failure．
The answer is the positive road paved （鋪滿） with faith and a belief that your best days are not behind you but ahead of you．With this belief you make the right choices and actions today that will create your positive future tomorrow．You stay calm，focused and committed to your purpose．You look for ways to save money and cut costs without making unreasonable fear-based decisions that sacrifice your future success．You identify opportunities in the midst of the challenges and you focus on solutions instead of problems．
Your faith and belief in a positive future leads to powerful actions today．The future has not happened yet and you have a say in what it looks like by the way you think and act．Fear or Faith．The choice is yours．

41．According to the passage，we can know thatB．
A．Fear and Faith have nothing in common
B．both Fear and Faith trust something in the future
C．neither negative nor positive future will happen
D．people usually choose to believe in the positive future
42．What does the writer mean by saying"our bus can't be on two roads"？C
A．We usually choose the negative road．
B．We should choose the positive road．
C．We must choose either a positive or negative road．
D．Our belief about the future depends on our choice．
43．Which of the following about"Fear"is true？B
A．We should have fear because it is a gift． 
B．Reasonable fear helps to plan for future． 
C．Fear can bring cheese and risk to people． 
D．Leaders usually have oversized fear．
44．If we have faith in future，we willD．
A．have the best days ahead of us    B．be committed to saving money
C．stay away from any challenges     D．take powerful actions today
45．What does the writer intend to tell us in the passage？C
A．Fear is closely related to faith．
B．Life is full of fear and faith．
C．We should have faith in a positive future．
D．Wrong decisions sacrifice our future success．

17．Some colors people see late at night could cause signs of clinical depression．That was the finding of a study that builds on earlier study findings．They show that individuals who live or work in low levels of light overnight can develop clinical depression．Doctors use the word"clinical depression"to describe severe form of depression．Signs may include loss of interest or pleasure in most activities，low energy levels and thoughts of death or suicide．
In the new study，American investigators designed an experiment that exposed hamsters（倉鼠）to different colors．The researchers chose hamsters because they are nocturnal，which means they sleep during the day and are active at night．
The animals were separated into four groups．One group of hamsters was kept in the dark during their night-time period．Another group was placed in front of a blue light，a third group slept in front of a white light，while a fourth was put in front of a red light．
After four weeks，the researchers noted how much sugary water the hamsters drank．They found that the most depressed animals drank the least amount of water．
Randy Nelson heads the Department of Neuroscience at Ohio State University．He says animals that slept in blue and white light appeared to be the most depressed．"What we saw is that these animals didn't show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim（微弱）red light，they did not．"
Randy Nelson notes that photosensitive（感光）cells in the eyes have little to do with eyesight．He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle．
He says there's a lot of blue in white light．This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness．

25．Researchers use hamsters in the experiment becauseD．
A．they are similar to humans in dealing with colors
B．they are easy to observe and study
C．they are sensitive to colors like human beings
D．they are active at night and sleep during the day
26．What sign shows that the hamsters are being depressed？A
A．They drink less sugary water．
B．They don't sleep well．
C．Their eyesight becomes worse．
D．Their energy level becomes low．
27．Ctends to cause hamsters to be depressed．
A．Dim light 
B．Red light
C．Blue light 
D．Darkness
28．What can help people who work late at night to avoid being depressed？B
A．Not being exposed to dim red light when using computers．
B．Equipping their computer screens to put it more in the reddish light．
C．Living or working in low levels of light overnight．
D．Going to see doctors of clinical depression regularly for help．
