    2．Since the start of the deadly AIDS epidemic in the 1980s，scientists have been working towards a cure．Now，they may be close to finding one．
    Researchers have developed a method to cut the viral （病毒） DNA from a person's infected cells．It is called CRISPR/Cas9and it means the person could be virus-free．
    DNA is a substance that carries genetic information in the cells of animals and plants．
    This gene-editing took place in a scientific lab，but has not been tested on humans yet．
    "It's a big step，"said Kamel Khalili，Ph．D．He is lead researcher and chair at the Department of Neuroscience at Temple University in Philadelphia，Pennsylvania．He and his team made the discovery．
    But more tests have to be done to know if it will be a cure for the millions of patients infected with the HIV virus，which causes AIDS．
    Antiretroviral drugs have been doing a good job of keeping the AIDS virus from reproducing．Such a good job that levels of HIV are just about undetectable in infected people who take the medicine．
    But even with the drugs，the virus stays in the body's"T-cells，"which are T-lymphocytes．AIDS damages the immune system，hurting the body's ability to fight off disease．
    So the drugs are kind of a"Band-Aid solution，"Khalili explained．They keep the virus from growing．But they do not remove the memory of the virus from the cells．
    And，the moment antiretroviral drugs are stopped，the HIV comes back to life and begins making more HIV，which is the AIDS virus．
    Khalili and his team of scientists appear to have found a way to cut this viral DNA from infected people's cells．
    In their lab，they took cells from people infected with the HIV virus．They removed the part of the cell that was holding the virus．
    He said they had"in some cases，near 90percent of the virus replication （复制） or production dropped in the patient samples after treatment in the laboratory．"
    Khalili and his team have not actually cured any patients yet．However，he believes this gene-editing technology could possibly cure AIDS．
    "Removal of the virus can lead to the cure．"He said，"it's an exciting time，and the reason is the technologies are available and the methods are in place and our knowledge has increased．"
    "And hopefully，there will be funding to take us toward this exciting moment for developing the cure strategy by getting rid of viral DNA using editing techniques．"
    62．The newly found way is intended to cure AIDS byB．
    A．doing damage to the immune system
    B．removing viral DNA from infected cells
    C．doing research into antiretroviral drugs
    D．taking cells from those infected with the HIV virus
    63．What can we know about antiretroviral drugs from the passage？C
    A．They are likely to make more AIDS virus．
    B．They can help body to fight against disease．
    C．They are unable to cure people of their HIV virus．
    D．Virus will disappear from T-cells because of them．
    64．Kamel Khalili's words in the last two paragraphs indicate thatD．
    A．his new method is bound to be a perfect cure for AIDS
    B．antiretroviral drugs will be dropped in the near future
    C．their discovery has made great contributions to human beings
    D．they will succeed curing AIDS if they aren't lacking in money．

    2．Have you ever run into a careless cell phone user on the street？Perhaps they were busy talking，texting or checking updates on WeChat without looking at what was going on around them．As the number of this new"species"of human has kept rising，they have been given a new name-phubbers（低头族）．
    Recently，a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight．In the short film，phubbers with various social identities bury themselves in their phones．A doctor plays with his cell phone while letting his patient die，a pretty woman takes selfie（自拍） in front of a car accident site，and a father loses his child without knowing about it while using his mobile phone．A chain of similar events eventually leads to the destruction of theworld．
    Although the ending sounds overstated，the damage phubbing can bring is real．
    Your health is the first to bear the effect and result of it．"Constantly bending your head to check your cell phone could damage your neck，"Guangming Daily quoted doctors as saying．"the neck is like a rope that breaks after long-term stretching．"Also，staring at cell phones for long periods of time will damage your eyesight gradually，according to the report．
    But that's not all．Being a phubber could also damage your social skills and drive you away from your friends and family．At reunions with family or friends，many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere，Qilu Evening News reported．
    It can also cost you your life．There have been lots of reports on phubbers who fell to their death，suffered accidents，and were robbed of their cell phones in broad daylight．

    28．For what purpose does the author give the example of a cartoon in Para.2？B
    A．To warn doctors against using cell phones while treating patients．
    B．To inform people of the bad effects of phubbing．
    C．To indicate the world will finally be destroyed by phubbers．
    D．To advertise the cartoon made by students．
    29．Which of the following is NOT a risk a phubber may have？A
    A．He will cause the destruction of the world．
    B．His neck and eyesight will be gradually harmed．
    C．He might get separated from his friends and family．
    D．His social skills could be affected．
    30．Which of the following may be the author's attitude towards phubbing？B
    A．Supportive．
    B．Optimistic．
    C．Opposed．
    D．Objective．
    31．What may the passage talk about next？D
    A．Advice on how to use a cell phone．
    B．People addicted to phubbing．
    C．Consequences of phubbing．
    D．Measures to reduce the risks of phubbing．

    3．Blind photography sounds strange．But a striking exhibition of photographs in California argues that it develops as a result of the contemporary art．The show"Sight Unseen"，at the California Museum of Photography until Aug．29，includes everything：underwater scenes，landscapes，abstracts and everything else you might expect from a"sighted"photographer．
        How do the blind take their photographs？Some rely on assistants to set up and then describe the shots （镜头），and others just point and shoot in the right place．"Just like any good artists，"says McCulloh．"They have their unique ways of operating．"One participating photographer is Pete Eckert，an artist with multiple degrees in design and sculpture who only turned to photography after losing his vision in the mid-1990s．He opens the shutter （快门） on his camera and then uses flashlights，lights，and candies to paint his scene on film．A former fashion photographer in Chicago，Weston，lost his vision due to AIDS in 1996 and focuses on images of destruction and disability．His photos are also a star of the show．
        What do gallery-goers say？"I was very impressed by it．The technique and experience was amazingly different，"says John Hesketh，a printmaker in Anaheim．"You never have a sense of feeling sorry for these people because they've worked very hard to prove their value．"
        Beyond the praise，however，the exhibition also makes a great example for disabled people everywhere．That point was explained in early May during a discussion on the TV show．At the very end of the talk，one attendee expressed his opinion．"This exhibition is extraordinary and revolutionary for many reasons．I think that by being an artist with a disability，you are continuing the work of those people who fought for basic civil rights to gain access and to have a voice．In that way，it's so wonderful that your photographs say it all．"
    63．From the passage we know that some blind people take photos byB
    A．describing the things to their assistants
    B．holding the camera and shooting randomly
    C．opening the shutter with the help of others
    D．using special equipment designed for them
    64．We can learn from the passage that blind photographersC
    A．were not born blind
    B．do jobs related to art
    C．focus on different subjects
    D．like photos of destruction
    65．What is people's reaction to the blind photography show？A
    A．They admire the blind photographers'hard work．
    B．They feel really sorry for those blind photographers．
    C．They think some have good techniques while others not．
    D．They can understand （lie real meaning of each photograph．
    66．The significance of the exhibition lies in the fact thatD．
    A．the California Museum of Photography receives praises for holding the show
    B．the public have a chance to know what the blind people are concerned about
    C．the blind photographers have a good place to show their works
    D．the exhibition can be very inspiring to the blind in the world．
