        The next (绣球花) you grow could really save your life. A biologist at Colorado State University has taught plant proteins how to spot exp/osfves1 (炸药) . 

        Picture this at an airport: A terrorist rolls through the sliding doors of a station with a bomb packed into his luggage. All of a sudden,the leafy,green hydrangea ringing the gates goes white 往s a sheet. That's  the proteins inside the plants telling the authorities that they* ve picked up the chemical trace of the terrorist's  explosive.

       “Plants can't run and hide,” says June Medford,the biologist who's spent the last seven years figuring out how to get the plant to fight against terrorism. “If an insect comes by,it has to respond to it. And it already has its own particular way to respond.”

        That would be the “receptor (受体)” proteins in its DNA. which respond naturally to threats. If an insect chews on a leaf,for instance,the plant releases a series of chemical signals called terpenoids,Medford says,that thickens the surface of the leaf in defense.

         Medford and her team designed a computer model to direct the receptors: Basically,the computer program instructs the protein to react when it comes in contact with chemicals found in explosives or common air or water pollutants.

Right now,Medford's  labs have genetically designed plants going white when they come into contact with explosives. But that's in a research lab,where the amount of light is constant.

Medford says her goal is to get her plants as sensitive as a dog's nose. But there is one big problem: Medford probably thinks it's   not easy to get the plants to react to ammonium nitrate,a common chemical used for home-made bombs.

9. If the hydrangea discovers explosives,it will .

   A. change color              B. produce flowers

   C. make its leaves thinner   D. give off a special smell

10. The underlined word “it” in Paragraph 3 refers to.

   A. the explosive     B. the plant

   C. the insect        D. the terrorist

11. What do we learn about Medford's  technology?

   A. It will come into use in two years.

   B. It has been studied for seven years.

   G. It is chiefly based on medical science.

   D. It can help spot ammonium nitrate easily.

12. What would be the best title for the text?

   A. Fight against terrorism in your garden

   B. Plants know how to respond to threats

   C. Biologist develops bomb-spotting plants

   D. Plant proteins hav^ been used to attract insects

            After a young woman texted DoSomething.org with a heartbreaking cry for help,the non-profit volunteer group's CEO, Nancy Lublin,knew she needed to do something. She decided to create a way for people struggling with crises (危机) in their lives to release their strong feelings. She quickly founded a separate organization called Crisis Text Line,a free 24-hour nationwide mental health service that gives people access to crisis coimse/ors (辅导顾问) right at their fingertips.

             “Since it was started in 2013,the service has exchanged nearly 10 million texts from people experiencing mental health issues,bullying and more ,” Lublin said. “About 30 percent of messages the program receives refer to suicide and depression.”

              The beautiful thing about Crisis Text Line is that these are strangers counseling other strangers on the most private issues,and getting them from ‘hot moments,to 'cold moments'，” Lublin explained in a TED Talk about the service.

              While all crisis lines are important and save lives,Crisis Text Line stands out because it can also provide important information to help prevent these events from happening in the first place. Since it was started,the program has been studying messages,the timing of messages and their locations to get usefiil data. For example,analyses show that texts about issues with eating disorders seem to increase on Mondays. Analyses also show that Montana is the state with the greatest number of texts that mention suicide.

             Lublin hopes that the information that Crisis Text Line can glean will help inform new policies in schools,governments and homes across the country. “Data evidence makes policy,research, journalism,policing,school boards(教育委员会)，and almost everything better,” she said. “I don't think of myself as a mental health activist. I think of myself as a national health activist.”

1. After reading the text from a young woman,Nancy Lublin decided to .

   A. start a profit volunteer organization

   B. become a professional crisis counselor

   C. learn about mental crises in people's lives

   D. help people easily get counseling about life crises

   C. It offers useful advice to victims.

   D. It analyzes information for better use.

3. According to analyses,people in Montana tend to be concerned with .

         You can tell a lot about people by looking at their hair 一 not just whether they brush,spray,or blow-dry. Scientists have found a way to use hair to figure out where a person is from and where that person has been. The fTnding could help solve crimes among other useful applications.

          Water is central to the new technique. The liquid makes up more than half an adult human's body weight. Our bodies break water down into hydrogen (氢) and oxygen. Atoms of these two elements end up in our tissues,fingernails,and hair.

           But not all Water is the same. Hydrogen and oxygen atoms can vary in how much they weigh. In the case of hydrogen,for example,there are three types according to their weights. Each type is called a hydrogen isotope (同位素) .And depending on where you live,tap water contains different isotopes.

            Can hair record this information? That's what James R. Ehleringer,an environmental chemist at the University of Utah,wondered. To find it out,he and his colleagues collected hair from hair stylists in 65 cities in 18  states across the United States. Even though people drink a lot of bottled water these days,the researchers have found that people's hair has the same isotopes as found in the local tap water. That's  probably because- people usually prepare their food with the local water.

            Authorities can now use the information to analyze hair samples from criminals,or crime victims and to narrow their search for clues. For example,one hair sample used in Ehleringer's study came from a.man who had moved from San Francisco to Salt Lake City. As his hair grew,it reflected his change in location.

5. What do we know about the hydrogen isotopes,according to Paragraph 3 ?

   A. They are classified by^?ize.

   B. Each type of them differs in weight.

   C. They can improve the quality of tap water.

   D. Some of them cannot combine with oxygen.

6. Why is it possible to know where people are from by analyzing their Hkir?

   A. People use the same bottled water.

   B. People wash their hair in different ways.

   C. People's hair is affected by the weather of the places they stay.

   D. People's hair indicates the type of water in the places they stay.

7. The last paragraph is mainly to show .

   A. how to recognize criminals

   B. how to collect hair samples

   C. the usefulness of hair analysis

   D. the process of Ehleringer's study

8. Where does this text probably come from?

   A. A lesson plan.       B. A news report.

   C. A physics textbook.  D. A tourist guidebook.

            Bom in Mississippi in 1897,William Faulkner is considered the master of stream-of-consciousness,a revolutionary literary technique. His novels rank among the most important books of the 20th century.

            It is clear that Faulkner,s Deep South (the most southern states of the US) roots greatly influenced his writing. He grew up surrounded by traditional folk tales,family stories,and accounts from the Civil War. His remarkable understanding of race relations and his clever satire(讽刺) of Southern characters came from his memories of growing up in Lafayette County,Mississippi. It was there that William Faulkner began to write on the great political,social,and economic transformation taking place in the Deep South. He set many of his short stories and novels in Yoknapatawpha County,a fictional place he developed from his hometown.

            In his works,Faulkner examined how traditional values and beliefs affected Southern society after the Civil War. Faulkner particularly hated the racism and abuse that African Americans suffered in the South. Although Faulkner,s novels do riot avoid describing the cruelty and pain that life can bring,his works are filled with sympathy and humor. His work explores,condemns,and analyzes barriers to human freedom and happiness by examining racism,shames fear,and false pride.

            Among his masterpieces is The Sound and the Fury,published in 1929. The novel tells the story of a well-known Southern family,relying most heavily on stream-of-consciousness writing,in which a character's thoughts and feelings are conveyed in a manner similar to the way the human mind actually works. (The technique,in other words,is the expression of thoughts and feelings exactly as they pass through your mind,without the usual structure they have in formal writing.) 

           Faulkner's  mastery of unique literary styles was formally recognized when he was awarded the Nobel Prize for literature in 1949. Always his own fiercest critic,William Faulkner considered many of his books failures because they did not live up to his high expectations. However,it is clear that Faulkner's experimental literary techniques often puzzled and challenged his readers,who were more,often than not inspired by his in-depth analysis of the human spirit. Faulkner passed away in 1962.

          The “e”in e-sports stands for electronic. Instead of playing physical games,people play games on a computer. Most of these games are played on the Internet.

          People love e-sports for the same reasons as people love many other sports. The competition is fun. The play is exciting to watch. The players are highly skilled. However,people like e-sports for another key reason. The sport of video games creates new,exciting worlds. In the games,people can do things that they cannot do in normal life.

          South Korea is the global center for professional e-sports. In South Korea,places called PC Bangs are Very popular. They usually have one big room filled with many computers. There are no windows. People pay to play the games. They can also buy energy drinks and food. Young people spend many hours there.

          Many people are concerned about the problems that can come with e-sports. One main problem is technology addiction (瘾) . Young people can especially play so many games that they cannot stop. Some experts believe that half of South Korean children have problems because of using computers and the Internet too much. Therefore,the South Korean government made a special Shutdown Law in 2011. According to the law,children under 16 are not permitted to use the Internet between midnight and six in the morning. Today,parents are responsible for setting rules for their own children. Also,the government established technology addiction treatment centers,which treat millions of people every year.

         One of the biggest problems in e-sports is drugs. Many players often take drugs to improve their performance. However,using drugs can be very dangerous. Bjoem Franzen worked in the e-sport business for many years. He wrote in his blog, “Using drugs in e-sports is one of the industry’s  secrets. It is a natural thing for some League of Legends players to take different kinds of drugs before a game. They will even do this to extend their training for a few extra hours.”
