user: Problem: Write a multi-choice question for the following article: Article: American researchers have developed a technique that may become an important tool in fighting AIDS virus from attacking its target-cells in the body's defense system.When AIDS virus enters the blood,it searches for blood cells called T4 lymphocytes .The virus connects to the outside of T4 lymphocytes.Then it forces its way inside.There it directs the cells' genetic material to produce copies of the AIDS virus.This is how AIDS spreads. Researchers think they may be able to stop AIDS from connecting to T4 ceils.When AIDS virus finds a T4 cell,it actually connects to a part of the cell called CD4 protein. Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood.This way the AIDS virus will connect to cloned protein instead of the real ones.Scientists use genetic engineering methods to make the clones.Normally a CD4 protein remains on the T4 cell at all times;the AIDS virus must go to it. In a new technique,however,the cloned CD4 protein is not connected to a cell.It floats freely,so a lot more can be put into the blood to keep the AIDS virus away from real CD4 protein on T4 cells.One report says the.AIDS virus connects to cloned protein just as effectively as it connects to real protein.That report was based on tests with blood cells grown in labs.The technique is just now beginning to be tested in animals.If successful,it may be tested in humans within a year.

A: Question: The new technique can  _  .Options:A cure AIDSB kill the AIDS virusC prevent the AIDS virus from spreadingD produce new anti-AIDS cellsAnswer:C


Problem: Write a multi-choice question for the following article: Article: People always think about "the problem of youth". If there is one -which I take leave to doubt- it is older people who create it, not young themselves. Let us get down to fundamental s and then the young are after all human beings -people just like their elders. There is only one difference between and old man and young one: the young man has a beautiful future before him while the old man a splendid future behind him and maybe that id where the rub is. When I was a teenager, I felt that I was just young and unknown -that I was a new boy in a hug w school, and I would have been very pleased to be regarded as something so interesting as a problem. For one thing, being a problem gives you a certain identity, and that is one of the thing s the young are busily engaged in seeking. I find young people exciting .they have and air of freedom, and they have not a dull promise to mean ambitious or love of comfort .they are not anxious social climbers, and they have no devotion to important things .all this seems to me to ling then with life, and the origin of things .it's as if they were some sense of cosmic beings in violent and lovely contract with us suburban creatures. all that is in my mind when I need a young person .he may be too proud, ill-mannered or self-satisfied, but I do not turn for protection to boring cliches about respect for elders as if age were a reason for respect .I accept that we are equals, and I will argue with them, as an equal, if I think he is wrong.

A: Question: One of the thing s the young are engaged in is that they want t o  _Options:A climb up the social ladderB have freedomC be knowD make troublesAnswer:C


Problem: Write a multi-choice question for the following article: Article: Like many men at some point, I dream about opening a bar. I plan to call it Work Out. It will cater to married women in need of a little fun. On Friday nights, they will be able to come here and enjoy themselves. See, I have a gift for business. I am, as my wife Zsa Zsa likes to note, "A man with a million ideas, none of them very good." Speaking of Zsa Zsa, she is fed up with this plain little life I've made for us----too many kids, too many chores, mind - numbing debt. The other day, she said she thought we needed a new family car. _ I said, and saw my dear Zsa Zsa age about 20 years, and become her mother right before my eyes. Yes, money is our madness. Last year, we thought we had found a little _ when I published a book about the life here in suburban America. It sold 12 copies----six of them to my mother. Four other copies went to various aunts and uncles, who used them for martini coasters  , then sold them at yard sales. The two remaining copies went to perfect strangers. (I think I owe you dinner, whoever you are. Call me, OK? We'll arrange something.) When the book didn't take off, I wrote a TV show. Then I penned a short novel based on the earlier TV idea that didn't sell. Currently, I am at work on a set of encyclopedias . In a month, I plan to sell them door - to - door. Such is the life of a writer, sending off the most personal thoughts possible to his hard drive. I am a writer, but also the breadwinner in my family. I'm at the keyboard at 6 almost every morning, hoping to tap out one idea----just one----that will take us up the hill, to the mountain, to the top.

Problem: Write a multi-choice question for the following article: Article: Friday, December 30, 2011has been cut for the tiny South Pacific island nation, Samoa as it moved its time zone 24 hours ahead to catch up with Asia, New Zealand and Australia.On New Year's Eve, Samoa will Slave jumped to the west of the international dateline, which runs through the Pacific Ocean and broadly follows the 180 degree line of longitude  . Its Prime Minister said it would make it easier for Samoa to trade with their key partners."No longer shall we have people ringing us up on Monday from New Zealand and Australia thinking it is Monday when we are closing our eyes and praying at churches.And in the same way, on our Fridays when we ring up and already our contacts are holidaying on their Saturdays," he told Radio New Zealand on Friday. To help win public support, the government declared employers must still pay workers for the missing Friday, although banks will not be allowed to charge interest for the lost day. Countries are free to choose whether the dateline passes to the east or west, and Samoa's decision means all new maps will need to change.But some tourism operators are worried Samoa will lose business by losing its position as the last place on earth to see the sunset each day, although it is now one of the first places to see in each new day. Samoa, a country of about 180,000 people, used to be in the same time zone as New Zealand and Australia, but went back a day in 1892, celebrating July 4 twice and  _ itself with the United States.The date change is not the first major change in Samoa in recent years.In 2009, the country switched to driving on the left hand side of the road from the right hand side, in line with New Zealand and Australia.
