ASucculents(多肉植物)are plants with parts that are thick and fleshy,usually to stay wet in hot and dry climates.As a group,succulents include better-known plants,such as the aloe(芦荟)and the agave(龙舌兰),and many almost unknown plants.Succulents are easy to grow well.Step1Get the pots ready.Succulents need pots that will house the plant comfortably.The actual pot size will depend on the size of the plant.Make sure that you are not using either too large or too small a pot.·There should be3or more holes at the bottom of the pot.Clay(陶土)pots are the best.·Fill1/3of the pot with gravel(沙砾).Step2Prepare your soil.If you don’t want to use one of the ready-made succulent mixes available on the market,prepare your own.Mix up a nutritious(有营养的),well-drainable(排水好的)soil to use for planting.Step3Provide good sunlight.Succulents prefer bright light;therefore,place the pots in an area where there is plenty of sunlight,direct or indirect.An ideal sun exposure will be from dawn to12noon during the summer.Step4Fill the pots up to the desired level with the potting mix so that the tip of the roots will touch it.Then,hold the plant carefully at the center of the pot,allow the roots to hang inside and place the potting mix loosely around the roots until it covers them up.You may also knock the pot softly on the ground to settle the potting soil.Step5Water your plant.The first watering will be done on the third day of planting.The plant needs the soil to be dry for the first two days so that any harm to the root system can heal.Watering afterward will have to be done according to the species and growth rate of the individual plant.A good rule is that the soil mix should be allowed to dry up before the next watering.Succulents grow during summer and rest during winter.Watering is recommended twice a week during the summer,once a fortnight during early and late winter and once a month during the peak of cold weather.Step6Fertilize(施肥),during the summer growing season,as you would with other houseplants.Stop fertilizing entirely during the winter.The nitrogen content(含氮量)of the fertilizer should always be very low.21.How should you prepare a pot for a succulent?A.Try to avoid using a clay pot.B.Fill1/2of the pot with gravel.e a pot that is3times the size of the plant.e a pot with at least3holes at the bottom.22.Which is the best time to expose a succulent to the sun in summer?A.10am–12pm.B.12pm–2pm.C.2pm–4pm.D.4pm–6pm.23.How often should you water a succulent during early winter?A.Once a week.B.Twice a week.C.Once every two weeks.D.Once a month.24.What should you pay attention to when you fertilize a succulent?A.Not fertilizing it during the winter.B.Fertilizing the plant on the third day after planting.C.Making the fertilizer yourself.ing a fertilizer with a high nitrogen content.BWhen I was12years old,I already knew that my teen years were going to be the worst years of my life.I was a total outsider,bullied(欺凌)at school.I felt completely alone in my small town.But by starting to do volunteer work when I was14,I turned my problem into a passion for helping others. The opportunity to practice kindness made me feel like my life had a greater purpose.The more positive energy I shared,the more kindness and appreciation I received.I realized that my purpose in life would be to reach out to people,specifically teenagers,and help them feel less alone.Books were my true friends back then.I was so thankful that the authors wrote those books.The kindness they offered me with their books saved my life.One of my biggest dreams was to become an author so I could write books that would help other teenagers the way those books helped me.After surviving terrible experiences at school and at home,I made a choice to take the optimistic,positive road in the next steps of my journey.My dream career,one I thought was only possible for the authors I loved,is what I am doing now.I have been a full-time author of teen novels since2007and am grateful for this amazing opportunity to reach out to readers every single day.Kindness saved me when I needed help the most.Even small acts of kindness can change someone’s life.You never know what someone else is going through.But by practicing daily kindness,you become an architect of positive change.25.What was the author’s life like when he was12?A.Boring.B.Peaceful.C.Painful.D.Meaningful.26.How did the volunteer work benefit the author?A.It made him popular in his town.B.It helped him find the meaning of life.C.It helped him understand others’lives better.D.It helped to shape his dream career.27.Why did the author choose writing as his job?A.He was inspired by his teacher.B.He could pass positive energy to readers.C.He wanted to share his school experiences.D.He found he had a talent for writing.28.What does the author suggest readers do in the last paragraph?A.Say“no”to bullies bravely.B.Make positive changes in their lives.C.Treat others with kindness in daily life.D.Learn to care more about others’feelings.CSomething was cooking in Toby McCartney’s home in Scotland.The engineer and his two pals were melting down pot after pot of plastic in his kitchen.Plastic bottles,carrier bags–it all went into the melting pot.But McCartney wasn’t going mad,he was trying to create the perfect recipe for plastic roads.“We went through about600different plastics that we were mixing in before we found one that actually worked,”he told CNN.The final recipe was mixed in with ordinary asphalt(沥青)to create a stronger,longer-lasting road, explained McCartney.“We are wanting to solve two world problems.On one side we call it the waste plastic[problem],and on the other side,the poor quality of roads that we have to drive on today.”To make plastic roads,plastic waste is turned into tiny pieces and replaces20percent of the material that seals traditional roads.Every ton of plastic road material contains approximately20,000.To date,McCartney’s company has provided plastic that’s been used in roads in the UK,Canada,Australia and New Zealand.McCartney first saw plastic in roads while traveling in India.There,he saw how waste plastics were used to repair holes in roads across many cities.In fact,India has been using plastic in the construction of roads since the turn of the century.In November2015,the Indian government even made it a law to construct roads using waste plastic in most urban areas.However,a number of states have yet to begin using plastic in road construction,explained Indian environmentalist Almitra Patel.“Potentially,plastic roads will make it possible for a city or state or the whole country for that matter to create zero waste if one follows the rules,but it’s a long way from happening,”she told CNN.While plastic waste is a mounting issue,McCartney believes the material’s properties are perfectly suited for the creation and repair of roads.“At the end of the day,plastic is a great product,”he said.“It lasts for a long time, which is a problem if it’s a waste product,but not a problem if we want it to last.”29.Why was McCartney cooking plastic in his kitchen?A.To find a new way to break down plastic.B.To recycle waste plastic in a creative way.C.To create longer-lasting plastic bags.D.To find more types of plastics.30.What can we learn about plastic roads from the article?A.They are made mainly from plastic.B.They contain more plastic bottles than plastic bags.C.They are believed to last longer than traditional roads.D.They need to be tested more before being put into use.31.How does the Indian government promote building plastic roads?A.By placing advertisements.B.By making it a law.C.By inviting experts to explain the process.D.By introducing the technology from abroad.32.What does Almitra Patel think of the future of plastic roads?A.They might create some unexpected problems.B.They will produce many economic benefits.C.It’s unrealistic to build them across a whole country.D.It will take time and effort for them to become common.DThe college entrance examination is just around the corner.Tasks and tests will keep many of you stay up late every night,and you may plan to make up for the lost sleep time on weekends.But is it useful?A study published in the journal Current Biology shows that the habit of sleeping in on weekends doesn’t fix the damage done by lack of sleep during the week.Even worse,it may damage your health.In the study,which was conducted over10days,36healthy young men and women with different sleep requirements were divided into three groups.The first and second groups were asked to sleep nine hours and five hours a night respectively.The members of the third group slept for five hours on weekdays but rested as long as they wanted on the weekend.The researchers found that people who lacked sleep ate more snacks and gained weight quickly.However,this wasn’t the case with the first group.That could be partially due to the shifting(变化)of the biological clock and changes to certain body hormones,especially hunger hormones.In order to catch up on sleeping during weekends, people in the third group would habitually eat later.So,their biological clocks would be shifted,which also changed the release of hunger hormones.“The hormone leptin(瘦蛋白)decreases appetite(胃口),while the hormone ghrelin increases appetite,”explained US researcher Vsevolod Polotsky,“Sleep deprivation causes leptin to drop and ghrelin to rise,so you’re hungry and eat more.”And even if they tried to sleep for as long as they wanted to during weekends,according to researchers,it was still insufficient(不够的)to meet standard sleep time because they found it difficult to fall asleep.Moreover,they were more likely to show increased sensitivity(敏感性)to insulin(胰岛素)in both their muscles and their livers.“That helps us understand why it is that when we don’t get enough sleep,we have an increased risk for things like diabetes(糖尿病),”Polotsky told CNN,because“short,insufficient sleep schedules will lead to an inability to change blood sugar and increase the risk of metabolic(新陈代谢的)disease in the long term.”For this reason,the American Academy of Sleep Medicine recommends at least seven hours of sleep each night for adults and much more for children.33.What did the study published in the journal Current Biology find?A.Many adults can’t get enough sleep on weekdays.B.Catching up on sleep is harmful to the body.C.Men and women have different sleep requirements.D.Sleep quality is closely related to one’s weight.34.Why may people who don’t get enough sleep eat more?A.They need to create more energy.B.They have lower blood sugar than others.C.Their bodies release more leptin hormone.D.Their bodies release more hunger hormones.35.According to the research,lack of sleep may lead to______.A.bad temperB.mental problemsC.poor memoryD.metabolic diseases第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
