3、re reading levels for younger children,ages 2 8，remain largely the same.But the amount of time spent in reading each session has declined,from closer to an hour or more to closer to a half hour per session.When it comes to technology and reading,the report does little to counsel(建议)parents looking f

4、or data about the effect of e-readers and tablets on reading.It does point out that many parents still limit electronic reading,mainly due to concerns about increased screen time.The most hopeful data shared in the report shows clear evidence of parents serving as examples and important guides for t

5、heir kids when it comes to reading.Data shows that kids and teens who do read frequently,compared to infrequent readers,have more books in the home,more books purchased for them,parents who read more often,and parents who set aside time for them to read.As the end of school approaches,and school vac

8、eading a lot less for fun”？AIn paragraph 2.BIn paragraph 3.CIn paragraph 4.DIn paragraph 5.B解析：推理判断题。文章第一段提出“儿童更少地为了乐趣而阅读”，文章第三段利用了一些数据来支持第 1 页，共 6 页这一论点。由此可推知应该选B 项。3 Why do many parents limit electronic reading?AE-books are of poor quality.BIt could be a waste of time.CIt may harm children s healt

10、 groups for them.DTalk with their reading class teachers.A解析：细节理解题。根据第六段第一句“The most hopeful data shared in the report shows clear evidence of parents serving as examples and important guides for their kids when it comes to reading”可知家长应该起模范带头作用，鼓励孩子多阅读。故选A 项。B(2019 江西赣中南五校联考)Before I studied psycho

12、es him laughand the more reasons there are，the more powerful the joke will be.I was attending a stand-up comedy show in Egypt，and when the man started to make fun of pedestrians crossing streets，everyone laughed their heads off.The main reason why those people strongly laughed was that almost all of

13、 them felt angry towards pedestrians who crossed streets carelessly.The joke wasn t only funny，but it also made the audience feel that they were right about being angry at those pedestrians.That is,people were laughing both because of the funny joke and because of the happiness experienced as a resu

14、lt of the psychological support they got.The better a joke makes a person feel，and the more it includes other psychological factors，the more the person will like it.For example，if you envy one of your friends，and someone tells a joke that is funny and，at the same time，makes your friend seem stupid，t

15、hen you will probably laugh at it louder than if you weren t jealous of him.In short，we dont laugh only when we hear something funny;we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke.I strongly discourage you from making fu

16、n of anyone or belittling someone to make someone else laugh.All I want to explain is that if your joke supports a person s emotions，he will certainly like it a lot.【解题导语】本文主要分析了人们笑的原因。第 2 页，共 6 页文档编码:CE6A2L10R10K9 HO9N2P1J8P2 ZD10G9Q8H4B6文档编码:CE6A2L10R10K9 HO9N2P1J8P2 ZD10G9Q8H4B6文档编码:CE6A2L10R10K9
