Unit 3 Under the sea李仕才一、阅读理解。Grandparents who help out occasionally with childcare in their community tend to live longer than seniors who do not care for other people，according to a study from Berlin，Germany.“Having no contact with grandchildren at all can negatively impact grandparents health.This link could be deeply rooted in our evolutionary past when help with childcare was important for the survival of the human species，”said Sonja Hilbrand，one of the researchers.The findings are drawn from data on more than 500 people over age 70.Overall，after accounting for grandparents age and general state of health，the risk of dying over a 20year period was onethird lower for grandparents who cared for their grandchildren，compared with grandparents who provided no childcare.Caregiving was associated with a longer life even when the care receiver wasnt a relative.Half of all childless seniors who provided support to friends or neighbors lived for seven years after the study began，while nonhelpers lived for four years on average.“Caregiving may give caregivers a purpose of life because they may feel useful for others and society.Caregiving may be thought also as an activity that keeps caregivers physically and mentally active，”said Professor Bruno Arpino.Arpino noted，however, that caregiving is not the only activity that can improve health and that too many caring responsibilities can take away from other beneficial activities like working，being in social clubs，or volunteering.“Children should take_into_account their parents needs，willingness，and desires and agree with them on the timing and amount of childcare，”he suggested.“It is very important that every individual decides for himself/herself, what proper amounts of help means，”Hilbrand said，adding，“As long as you do not feel stressed about the intensity (强度)of help you provide you may be doing something good for others as well as for yourself.”1What is the caregiving study based on?AHuman evolutionary history.BDemand of modern society.CSocial contact between relatives.DData on many elderly people.2In Arpinos opinion，childcare _.Ais sure to keep old people away from illnessesBallows old people to live a more meaningful lifeCcreates more job opportunities for old peopleDmakes social activities inaccessible to old people3What does the underlined part“take into account”in Paragraph 6 probably mean?ALimit.
