11．My grandfather Andy Anderson is 99．His life story is one for the big screen--he met my grandmother on a Saturday，and they married on the following Saturday．They stayed together until my grandma died 67years later．
Without going to college，Andy worked his way to the top．He became the manager of the dairy department of Safeway．He earned the nickname Mr．Cheese，which eventually turned into Grandpa Cheese among the family．He has taught me a lot and here's what he has learned in his 99years．
Always maintain a good sense of humor．Find something humorous in every single situation．Never be too good to start at the bottom．Exercise every day，even when you don't feel like it．Don't spend more money than you make．Save your money now and spend it later．
You must be able to forgive，even if it's difficult to do．Love is not always easy； sometimes you have to work at it．Your family is the most precious thing you will ever have in life．
If you are faced with a problem，don't delay trying to figure it out．But if there's no way to figure it out，you have to forget about it．Make sure you're doing what you love； don't be afraid to follow those dreams you have for yourself．
School education is important，but not necessary．Life can be an education in itself．Explore your world and stay curious； Having a bad job is better than having no job at all； Try not to take yourself so seriously．Don't ever be afraid to be your true self．Your life is delicate，and if you fail to take care of yourself properly，you'11spoil．
Life is a gift that you must unwrap．It's up to you to determine if what's inside will lead you to happiness or frustration．You have the power to make that decision for yourself．
All of above come from Grandpa Cheese．If you're wondering what Grandpa Cheese is up to these days，he's riding his motorized scooter （踏板車） around Benicia，CA，and"planning on what I'm going to do when I start to get old，"he says．
29．Which of the following agrees with Grandpa's philosophy？D
A．Exercise if you like it．
B．A good job secures a happy life．
C．Happiness makes longer life．
D．Love needs efforts．
30．If you have a problem with no solution，the best way is toA
A．leave it aside          
B．have a sense of humor
C，take care of yourself     
D．keep trying
31．What can we learn from the passage？B
A．The author's great-grandparents are living a happy life now．
B．Whether life will be happy or miserable is decided by yourself．
C．School education helps develop curiosity about the world．
D．Andy was called Mr．Cheese before being a Safeway manager．
32．The passage is probably fromB．
A．An advertisement．
B．A biography．
C．A political newspaper．
D．A science fiction．

2．Scientists have linked the"fat gene"with the"happy gene"．They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends．The breakthrough could be an explanation for why fat characters，such as The Laughing Policeman and Father Christmas are often portrayed as joyful and kindly．
FTO is the major genetic contributor to obesity．But it is also associated with an eight percent reduction in the risk of depression．Researchers at McMaster University in Canada had been investigating whether there was a link between obesity and depression．They found the opposite was true．
The study analyzed 17，200DNA samples from participants in 21countries．Results showed people with FTO gene-the fat gene-showed significantly less signs of depression．This finding was confirmed by analyzing in three additional international studies．
Professor David Meyre said，"We set out to follow a different path，starting from the assumption that both depression and obesity deal with brain activity．We thought that obesity genes may be linked to depression．The difference of eight percent is not very obvious．But，we have discovered a molecular（分子的）basis for depression．It is the first evidence that an FTO obesity gene is associated with protection against major depression．
In a recent interview，actress Lisa Riley said she was more than comfortable with her size．She said she is a"big，really happy"girl who is lucky enough to be confident in her own skin，and added，"Many people want to be thinner．Not me．""I genuinely love being different and it drives me mad that people don't believe I'm happy with what I am．"
41．What does the underlined word"skinny"in Paragragh 1probably meanB？
A．Sensitive．
B．Very thin．
C．Fair-skinned．
D．Close．
42．According to the passage，what is FTOB？
A．A molecular linked to happiness．
B．A fat gene which leads to obesity．
C．A gene that contributes to depression．
D．A kind of DNA sample from participants．
43．According to what Professor David Meyre said，we can knowD．
A．his former assumptions were right
B．obesity genes are linked to depression
C．there should be more people involved in the study
D．there was no evidence for the role of an FTO obesity gene before
44．By mentioning the actress Lisa Riley，the author aims to show thatA．
A．fat people are really happier
B．it's not easy to be an actress
C．many people want to be thinner
D．Lisa Riley is lucky and satisfied with herself．
45．The passage is likely to appear inC．
A．a(chǎn)n advertisement
B．a(chǎn) lesson plan
C．a(chǎn) health magazine
D．a(chǎn)n amusement program．

19．We like to think our intelligence is self-made； it happens inside our heads，the product of our inner thoughts alone．But the rise of Google，Wikipedia and other online tools has made many people question the impact of these technologies on our brains．Is typing in"Who has played James Bond in the movies？"the same as our knowledge about the names like Roger Moore，Timothy Dalton，Pierce Brosnan and Daniel Craig？Can we say we know the answer as long as we know how to rapidly get the information on Google？
Here the question is about how we define intelligence itself．The answer appears to be interesting，because the evidence from psychological studies suggests that much of our intelligence comes from how we coordinate ourselves with other people and our environment．
An influential theory among psychologists is that we're cognitive misers（認知吝嗇者）．This is the idea that we are unwilling to do mental work unless we have to．We try to avoid thinking things fully when a short cut is available．If you've ever voted for the presidential candidate（總統(tǒng)候選人） with the most honest smile，or chosen a restaurant based on how many people are already sitting in there，then you are a cognitive miser．The theory explains why we'd much rather type a zip code into Google Maps than memorize and recall the location of a place-it's so much easier to do so．
Research shows that people don't tend to rely on their memories for things they can easily access．Buildings can somehow disappear from pictures we're looking at，or the people we're talking to can be changed with someone else，and often we won't notice-a phenomenon called"change blindness"．This isn't an example of human stupidity-far from it，in fact-this is an example of mental efficiency．The mind relies on the world as a better record than memory．
Philosophers have suggested that thinking is really happening in the environment as much as it is happening in our brains．The philosopher Andy Clark called humans"natural born cyborgs（電子人）"，those naturally capable of absorbing and combining new tools，ideas and abilities．In Clark's view，the route to a solution is not the issue-having the right tools really does mean you know the answers，just as much as already knowing the answer．
Rather than being forced to rely on our own resources for everything，we can share our knowledge．Technology keeps track of things for us so we don't have to，while large systems of knowledge serve the needs of society as a whole．I don't know how a computer works，or how to grow vegetables，but that knowledge is out there and I can get to benefit．The internet provides even more potential to share this knowledge．Wikipedia is one of the best examples-an increasingly large database of knowledge from which everyone can benefit．
So as well as having a physical environment-like the rooms or buildings we live or work in-we also have a mental environment，which means that when I ask you where your mind is，you shouldn't point toward the centre of your forehead．As research shows，our minds are made up just as much by the people and tools around us as they are by the brain cells inside our skull．

50．Why did the writer raise the questions in Paragraph 1？B
A．To find out who has played James Bond in the movies．
B．To introduce the topic to be discussed in the passage．
C．To show that he knows the answer to the questions．
D．To attract readers'attention by mentioning James Bond．
51．What is the writer's attitude towards the rise of technologies like Google and Wikipedia？A
A．Supportive    
B．Objective       
C．Indifferent    
D．Neutral
52．Which of the following might the philosopher Andy Clark agree with？D
A．Intelligence is something that is made by one's brain itself．
B．Intelligence is something that only happens inside one's head．
C．Intelligence is the product of one's inner thoughts alone．
D．Intelligence is a mixture of the environment，people and one's brain cells．
53．It is true about the phenomenon called"change blindness"that human beingsB．
A．a(chǎn)re stupid not to notice the changes
B．a(chǎn)re efficient in mental work
C．a(chǎn)re blind to changes around them  
D．rely on memory when dealing with things
54．According to the text，how do technologies like Google，Wikipedia affect us？A
A．They make us much more intelligent．
B．They make us lazier and more stupid．
C．They have little to do with our intelligence．
D．They have a negative effect on our intelligence．
