3．There is an English saying that goes，"he who laughs last，laughs the hardest．"High School Musical star Zac Efron is laughing a lot these days．
As a young boy，Efron waspicked on in school because he was always the smallest in his class and teased because he had a big space between his teeth．In sixth grade，Efron's basketball team made it to the league championships．In double overtime（兩個加時賽），with three seconds left，he rebounded the ball and passed it-to the wrong team!They scored and his team lost the game．
But history，as they say，is a thing of the past． Now at 21，Efron is one of People magazine's 100 Most Beautiful People，appears on the cover of Entertainment Weekly，Hollywood's most influential magazine，and is traveling the world promoting the third High School Musical film．Director Adam Shankman described Efron as"arguably the biggest teen star in America right now．"Simply geogle"Zac Efron"and you get more than 14 million responses．Yes，it seems Efron has a lot to smile about these days．
Efron was born and raised in California．He took school seriously．According to Efron，"he would go mad if he got a B and not an A in school，and that he was a class clown．"It was his father who encouraged him to act．He took part in school performances and with a local theater group．He also took singing lessons．He graduated high school in 2006 and was accepted at the University of Southern California to study film．But he postponed it-why study movies when you can star in them．
Now he has signed on to star in the romantic comedy Seventeen Again and to play in the remake of the hugely popular movie，F(xiàn)ootloose．Efron is also earning more than $3 million for his role in High School Musical 3．Not bad for a 21-year-old．But Efron still remembers those bullies（欺人者）．
"You always have to remember that bullies want to bring you down became you have something that they admire，"Efron said．"Also，when you get made fun of，when people point out your weaknesses，it's an opportunity for you to rise above"．
Efron has risen all the way to the top of the movie business．And he can now laugh all the way to the bank．
61．The English saying is used at the beginning to show EfronC．
A．has achieved worldwide fame      B．still has a long way to go
C．has a not so smooth past          D．is optimistie all the way
62．The underlined phrase"picked on"in Paragraph 2 is closest in meaming toB．
A．sung high praise for          B．treated unfairly
C．run after                   D．talked about
63．We know from the underlined sentence in Paragraph 3 thatD．
A．We'd better let the past be the past
B．Efron is bound to go down in history
C．history plays an important role in Efron's life
D．different from his past，Efron is quite popular now
64．Why did Efron put off his university study？A
A．Beeause he didn't want to lose the chance to star in films．
B．Because he had learned all the things about film．
C．Because he wanted to mke more money．
D．Because he showed no intorest in it．
65．What's the reaction of Efron to those bullies？D
A．Taking no notice of it．
B．Fighting back immediately．
C．Finding opportunities to fight back．．
D．Regarding it as a motivation to move on．

4．"Over the years the unthinkable has become thinkable and today we sense we are close to being able to alter human heredity（遺傳）．"These were the words of David Baltimore of the California Institute of Technology，on December 1st，when he opened a three-day meeting in Washington to discuss the morality and use of human gene editing．Dr Baltimore is an old hand at these sorts of discussions，for he was also a participant in the Asilomar conference，in 1975，which brought scientists together to discuss a safe way of using the then-new tcchnology of recombinant DNA，and whose recommendations influenced a generation of biotechnology researchers．
Four decades on，the need for a similar sort of chin-wag has arisen．The International Summit on Human Gene Editing has been held by the national scientific academies of three countries-America，Britain and China．They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line，something Dr Baltimore described as a deep and troubling question．Like those of Asilomar，the conclusions of this meeting will not be binding．But the hope is that，again like Asilomar，a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves，rather than having politicians and civil servants do it for them．The meeting is being held against a backdrop of rapid scientific advance，Since 2012 research into a new，easy-to-use editing tool called CRISPR-Cas9 has blossomed．This technique involves a piece of RNA （a chemical messenger，which can be used to recognise a target section of DNA） and an enzyme （酶） called a nuclease that can snip unwanted genes out and paste new ones in．
Public interest was aroused in April，when Chinese scientists announced they had edited genes in non-viable （ 無活力的） human embryos，and again in November when British researchers said they had successfully treated a one-year-old girl who had leukaemia （ 白血�。�，using gene-edited T-cells．T-cells are part of the immune system that attack，among other things，tumour cells．The researchers altered T-cells from a healthy donor to encourage them to recognise and kill the patient's cancer，to make them immune to her leukaemia drug，and to ensure they did not attack her healthy cells．
In another recent development，a firm called Edit as Medicine，which is based in Cambridge，Massachusetts，has said it hopes，in 2017，to start human clinical trials of CRISPR-Cas9 as a treatment for a rare genetic form of blindness known as Leber congenital amaurosis （伯氏先天性黑蒙）．Though other companies are already testing gene-editing therapies，these employ older，clunkier forms of the technology that seem likely to have less commercial potential．Moreover，researchers at the Broad Institute，also in Cambridge，said this week that they had made changes to CRISPR-Cas9 which greatly reduce the rate of editing errors-one of the main obstacles to the technique's medical use．
On the subject of germ-line editing，Eric Lander，the Broad's head，told the meeting it would be useful only in rare cases and said it might be a good idea to"exercise caution？before making permanent changes to the gene pool．The need for caution is advice that might also be heeded by those pursuing work in animals other than people，and in plants-subjects not being covered by the summit．
61．Which ofthe following is TRUE about CRISPR-Cas9？B
A．It has fewer side effects．
B．It can modify human gene．
B．It can protect immune system．
D．It has less commercial potential．
62．The underlined word"chin-wag"in Paragraph 2 can be replaced byA
A．discussion    B．negotiation  C．a(chǎn)rgument D．comparison
63．What can be inferred from the passage？D
A．Dr．Baltimore started his research on modiffing gene in 1975．
B．Scientists'opinions about the use of gene editing are consistent．
C．CRISPR-Cas9 has been applied to cure Leber congenital amaurosis．
D．More research should be made before the technology comes into wide use．
64．This passage is most probably aB．
A．science fiction  
B．scientific report
C．conference summary 
D．commercial advertisement．

1．I was in Houston a few weeks ago，and needed to be back home in Austin by midmorning the next day．Though I usually left in the evening，for some reason last time I had to choose to set off after midnight．
I was on my way back to Austin when I realized I left an important file，and knew I had to return to get it．I took the first exit I could，but when I rounded the corner，an 18-wheeler was stopped dead in the exit lane．I swerved（急轉(zhuǎn)彎） to avoid it，and then I realized that there was something wrong with my car．So I pulled into a small parking lot and unsurprisingly found the area deserted at 3：15am．I've lived in urban areas most of my life．I'm fairly street-wise and don't become frightened easily，but I knew I was in a pretty tough neighborhood．
There was no one in Houston to pick me up．I immediately locked the doors and picked up my phone to call a tow truck．Soon a young man knocked on my driver's side window and asked if he could help me．Judging from his appearance，he was far from a mad man，but I knew he was far more likely to rob than help me．So I lied to him．After a while，he asked again，but this time I politely refused and told him the tow truck was due any minute．He finally said，"Madam，you need help．A tow truck in Houston will arrive anywhere between 45minutes and approximately never （which I knew was true），and you aren't going anywhere until you change your flat tire．"
After considering thoroughly，I got out．He looked surprised，but got right to work．He changed the tire，returned the seat to its place and said，"Thank you for letting me help you．You gave me a chance when most people would never open the door to someone like me．Would it be okay if I gave you a hug？"When I recovered，I gave him a giant hug．I left with a new tire and a renewed faith in human nature．

D．Its tire blew out．
5．Why did the author lie to the man and refuse his help in the beginning？B
A．Because she thought the man was playing jokes．
B．Because she thought the man might be a bad man．
C．Because she thought the man wanted to get a lift．
D．Because she thought the man was a mad man．

A．Stubborn but brave．
