when the parents were treated with 5-azaC,and disappeared when the offspring weregrown in soil from shaded parents.The growth difference was also observed when theoffspring were grown under shaded condition and in soil from shaded parents.However,this difference was greater when the parents were treated with 5-azaC,and disappearedwhen the offspring were grown in soil from environmental parents.Our results show that light condition experienced by parents can influence offspringresponses to light through both parental effects and soil legacies.The parental effects weremediated (by changes in DNA and the soil legacies.These impacts may eventuallyinfluence the ecological and evolutionary track of clonal plant populations.32.What is the text mainly'about?A.Environmental conditions are important to offspring performance.B.Offspring performance can be controlled by DNA and the soil legacies.C.Environmental conditions experienced by parent plants can influence offspring.D.Light condition experienced by parents can influence offspring responses to light.33.How did the researchers get the result?A.They carried out a survey.B.They conducted an experiment.C.They analyzed existing data.D.They collected information from others.34.What can we learn from Paragraph 3?A.Growth difference only happens under environmental light condition.B.Offspring of environmental parents grow smaller than offspring of shaded parents.C.No growth.difference appears when offspring are grown in soil from shaded parents.D.Growth difference varies when parents are treated with 5-azaC under different conditions.35.Where is the text most likely from?A.A diary.B.A magazine.C.A novel.D.A notebook.第二节（共5小题；每小题2.5分，满分12.5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。选项中有两项为多余选项。People with satisfying relationships and positive emotions live healthier and longer.36Emotion regulation improves with age.We see improvement for most people,but not foreveryone.Why some people do not experience these improvements?Most of the people in.these studies are people from Western rich societies.37 Andmost of them are middle-class people who are employed.Compared to younger people ofcomparable status,the older people looked a lot better.But if they are in bad situations,you may not see these benefits.Are these the kinds of things that weigh on young people's minds?What's really important for emotional well-being is to know that your future is secure.Younger people are healthy and expect to have a long life ahead of them.38 As peopleget older,there is less time left and they start valuing emotional goals more.Older peoplewill spend time with family and friends.Is there a risk of becoming too emotionally comfortable?You can be so comfortable that you .no longer meet any challenges and you really needto stay engaged in cognitive challenges.In a recent study,we asked over 2,500 peopleabout the relatively minor stressors they had experienced.About 10 percent of the peoplereported never having experienced even one.They also reported being happier than thosewho reported at least one.39 They also reported having received or given less help toothers and that they had spent more time watching TV.高三英语第5页共8页
