Marcos,Age 14When his neighbor's home was burning,Marcos climbed into the burning home and saved the life of an 8-year-old girl,who was inside the house.Marcos,like a true hero,said, "I can't say I am a hero.I think anyone would have done what I did."Riley,Age 5Riley was swimming in a pool,when she noticed an 18-month-old toddler（蹒跚学步的孩子）fall in.Riley,a strong swimmer,was going to call for help,but she couldn't see any adults nearby.So,Riley saved the girl from the bottom of the pool herself.When she got out of the water,she yelled,"I've got the baby!I've got the baby!"Jaden,Age 9Jaden was staying at home on a Sunday,when two robbers（劫匪）entered his house.Jaden,beingthe smart kid that he is,hid in a closet.When he heard his parents talking to the robbers in the living room,he made a run for it,out a bedroom window and to a neighbor's house.The neighbor called 911 and when the officers arrived,the two robbers were still in the house.Piper,Age 10Piper,who is blind,was outside playing with her little brother and friend Irie when a raccoon（浣熊）was trying to hurt Irie.Piper asked Irie to describe the animal to her,then used a stick to beat at the raccoon until it let Irie free.There were six bites on Irie's body,but it would have been much worse if Piper hadn't stepped in.31.How old is Marcos______A. 10.B. 9.C. 14.D. 5.32.According to the passage,we know that Riley is ______ .A. a brave boyB. a blind girlC. a fast rummerD. a good swimmer33.Which of the following is TRUE about Jaden？______A. Jaden is a very smart kid.B. Jaden is afraid of strangers.C. Jaden can fight bad people.D. Jaden called 911 to get help.34.According to the passage,we can learn that ______ .A. Irie was Piper's elder sisterB. Piper's little brother hurt herC. Irie knew a lot about animalsD. Piper made the raccoon leaveWMy mother was having a baby,and we were very glad.We did not know when the baby would come,but we knew it was soon.My mother had a suitcase she had packed（收拾）.She kept it next to the door.She had put some things she would need when she went to the hospital in it. Then one night my mother woke us up and said, "It is time!"We were very.excited.She said that my aunt would take care of us while she was at the hospital.I wanted to go,too,but she said I would come later. "Go back to sleep," she said. "I will see you soon with the new baby."The next morning,my aunt said,"Now you have a new brother." I was glad.I wanted to see him,but my aunt said, "You can't come to the hospital.You are too young." Still,I wanted to see the baby,and I missed my mother.My mother called me on the telephone.She stayed in the hospital for a few days,and I hadmissed her even more.When I talked with her on the phone I felt better.She said she was feeling good and would be home soon.She said the nurses had taken good care of her.The next day,I went to the hospital.We were taking my mother home,and my aunt drove us there.When we got there,my mother was in a wheelchair.I thought there was something wrong. "Are you sick？" I asked.The nurse said, "No,she is just being careful.When patients leave the hospital they leave in a wheelchair.That keeps them safe."My mother thanked the nurse.She said she and the baby would be back next week to see the doctor.She would bring us,too.She said this was a very special time for our family.We would all help take care of each other.We would take good care of my brother.We would return to the hospital to check with the doctor to make sure he was healthy.35.The mother might feel ______ before going to hospital.A. sadB. afraidC. excitedD. surprised36.From the passage we know that the writer had a（an）______ .A. little sisterB. little brotherC. elder sisterD. elder brother37.Which of the following statements is TRUE______A. The mother was sick in bed.B. The aunt didn't like the new baby.C. The new baby was in poor condition.D. The writer loved his family very much.XI enjoy baseball and I like cheering for the hometown team.So my son and I decided to attend an evening of postseason baseball this week when the Arizona Diamondbacks hosted the Los Angeles Dodgers.If you follow baseball,you know the Diamondbacks lost the game...and the series...and their season ended that night.In that regard,the night was a bummer（失望）.But in every other way,the evening was close to perfect.The crowd was cheerful.The weather was amazing.The food was delicious.And the conversation was excellent.We make choices every day with our financial resources（财力资源）.But this particular night of baseball was a helpful reminder to me that experiences are almost always better than things.Experiences result in greater happiness.According to research,experiences result inlonger-lasting happiness than material possessions（拥有）.The happiness provided by new material possessions is short-lived.Over time,people's satisfaction with the things they buy decreases,whereas their satisfaction with experiences over time increases..One reason I enjoy baseball so much,is undoubtedly,because of the many memories I have watching it with my father.Growing up in South Dakota,an annual trip with the family to watch the Minnesota Twins play was a highlight of summer.Decades later,I look back on those moments with great joy and fondness.I remember them far better than almost any of the physical gifts.Experiences result in less clutter （杂乱） .Most physical possessions eventually become a burden on our lives.They take up physical space in our homes and mental space in our minds.Experiences,on the other hand,are accompanied with little to no physical baggage.The only thing I brought home with me from the game were a few photos on my phone. Experiences provide greater opportunity to connect with other people.This is the nature of experiencing things with others.Because we enjoy time together around a common purpose and activity for an extended period of time,we are afforded numerous opportunities to talk and connect with one another. Experiences result in greater mindfulness.In 2010，Matthew Killingsworth and Daniel Gilbert published an important study in Science magazine.Their research concluded that "a wandering mind（不专注的心）is an unhappy mind."And the greater a person's ability to "stay present" in a given moment,the greater happiness they experience during and after.Experiences result in less comparison with others.According to research done by RyanT.Howell and Graham Hill,another significant reason experiences result in more happiness than material possessions is because experiences result in less comparison with others.38.What can we learn from the first three paragraphs？______A. Everything else was enjoyable that night.B. Diamondbacks lost the game in Los Angeles.C. The baseball season was a bummer that night.D. The result of the game cheered the writer and his son up.39.Which could be the first sentence in paragraph 5？______A. Experiences result in happy families.B. Experiences provide better memories.C. Experiences create good relationships.D. Experiences end up with physical gifts.40.According to the passage,which of the following statements is TRUE？______A. Experiences help us achieve more possessions.B. Joyful moments take up space in our homes and minds.C. People experience more happiness from gifts over time.D. Shared memories bring people closer in a continuing time.41.The writer suggests that we should ______ through experiences.A. stay focusedB. live a full lifeC. enjoy the imperfectionsD. be satisfied with ourselvesYScientists at MIT （Massachusetts Institute of Technology）have managed to change spinach plants into natural sensors which can detect （探测）chemicals used in ing a cheap and small computer system,the spinach can even help send a warning email.The secret to giving spinach these special powers is nanotechnology（纳米科技）.Nanotechnology,or nanotech,is a scientific area that deals with making or changing things that are super tiny.Nanotech is measured in nanometers - one billionth of a meter.The MIT researchers are interested in using nanotech to give plants new abilities.They say plants are already great at sensing their environment,since they take in water from the ground,and react to chemicals in it.Plants also supply their own energy,which the scientists can use to power their tiny experiments.For this experiment,the scientists placed two different kinds of nanotech materials,tiny sensors and carbon nanotubes,into spinach plants.Nanotubes were used to make the plants give off a special light.To get the tiny materials into the plants,the scientists put a-liquid containing,the.nano-materials （包含纳米材料的液体）on the bottom of the plant's leaves.That's where the plants take in carbon dioxide gas.Then the plants took in the tiny materials.Once the tiny sensors and nanotubes were in the spinach leaves,the plant did the rest of the work.The carbon nanotubes in the leaves,using some of the plant's energy,give off a special kind of light.The scientists are able to detect this light by shining a laser（激光）at the plant's leaves and measuring the light.As part of its natural process,the spinach plant pulls water through its roots and into its leaves.If the water contains certain chemicals that are used in bombs,the sensors in the leaves make the nanotubes give off a different kind of light.By watching the plant closely using a camera connected to a cheap computer,the scientists set up a system that can send a warning email if chemicals from bombs are detected in the water. The researchers say it takes about 10 minutes for the plants to react to the chemicals.It is almost like having the plant talk to us about the environment they are in.The scientists say that in the future,their system could even use a cell phone with its camera changed slightly.Detecting chemicals used in bombs is just one of the many uses the researchers are exploring.They've used plants to detect and report on several other dangerous chemicals as well. The scientists believe that in the future,such systems could give farmers detailed information about the health of the land water on their farms.42.Scientists gave spinach plants new skills through ______ .A. powerB. chemicalsC. nanotechD. computer43.Which of the following statements is TRUE about the process of experiment？______A. Nano-materials are put in the roots of the plants.B. Sensors contain special liquid for plants to take in.C. Nanotubes give off tight with the help of carbon dioxide gas.D. Dangerous chemicals are detected by the sensors in the leaves.44.From the passage,we can learn that ______ .A. the energy of the plants helps make it happenB. plants are good at reacting to the environmentC. it takes the plants seconds to notice chemicals from bombsD. scientists are able to see the change in the leaves of the plant45.What can we infer from the passage？______A. Spinach takes in chemicals to make bombs.B. P lants will serve farming better in the future.C. Scientists can improve cell phones with spinach.D. Scientists will put nanotech to other practical use.46.Which could be the best title of the passage？______A. Plants' New Abilities Help Improve Farming.B. Spinach Plants Has Magic Powers to Make Bombs.C. Nanotechnology Taught Spinach to Send Emails.D. Scientists Create Spinach that Can Test for Bombs.47.Experts in the United States have the following suggestions for living a healthier lifestyle：Get active.Ride a bike or walk to places\instead of driving.Cars and other machinesgreatly reduce the need for physical activity.These machines help us move from place to place easily and quickly and work well,but we don't use much physical energy.Eat a well-balanced meal made of protein（蛋白质），grains,vegetables,and fruit.Some people just eat snacks all day.They eat a lot of junk food,such as potato chips and soda.Nutritionists（营养学家）suggest that families eat together.Unfortunately,many people often eat alone and quickly.If families eat their big meal together slowly,they can discuss the events of their day and enjoy their food and each other's company.Take the soft drink and snack machines out of the schools and educate children early about nutrition and exercise.The typical teenager gets about 10 to 15 percent of his or hercalories from soft drinks,which have no nutrition at all.Replace the food in the machines with water,juice,and healthy snacks.Be careful of food messages you hear from advertisers that say,"Eat this.Buy that."Technology allows advertisers to send us messages all the time.Many of these foods are high in fat and calories.Choose natural foods,such as fruits and nuts,instead ofmanufactured（加工的）foods.In addition to what individuals （个人）can do,communities need to build new housing more carefully.In many communities in the United States,it's hard to walk from place to place easily because there are no sidewalks.If we want people to get exercise in theircommunities,they need sidewalks.They also need bike paths so they can ride safely.Change your diet.Eat meat infrequently.Twice a week is chough.Parents need to set a good example so that their kids grow up in a healthy way.How can we get active______What is a well-balanced meal made of______How often should we eat meat to keep healthy______What is the passage mainly about______48.我父母去过上海两次了。
